Abstract

A wound dressing (10) includes a cover membrane (22) comprising a semi-permeable material with an adhesive-coated (30) skin contact surface (28). An opening (32) is formed in an interior portion of the membrane. An intermediate layer of material may be placed between the wound and the membrane contact surface for either absorbing fluids from the wound, e.g. with a hy-drocolloid or hydrophilic material, or for passing such fluids to the opening with a synthetic material, e.g. rayon. A tube (34) in-cludes a proximate end (36) fluidically communicating with the wound through the membrane opening. A distal end (38) of the tube is adapted for connection to a suction source (47) for draining the wound or a fluid source for introducing liquid medication to the wound. Both evacuation and introduction can be either active or passive. A wound treatment method is also disclosed.

Description

FLUIDIC CONNECTION SYSTEM AND METHOD
Backq:round of the Invention 1. Field of the Invention.
The present invention relates generally to fluidic connection systems, and in particular to systems for draining liquids from and introducing liquids to patients.
2. Description of the Relevant Art.
Various types of fluidic connection systems have heretofore been devised to meet the requirements of particular applications. In the medical field, fluidic connection systems find many applications, including wound dressings and systems for introducing fluids to and removing fluids from patients.
Wound dressings are typically applied over various types of wounds to promote healing and to reduce the risk of infection. Although various types of dressing materials have been successfully employed, membranes comprising semi-permeable materials are often preferred because they can increase patient comfort and lower the risk of infection. Semi-permeable membranes generally pass moisture vapors, but are generally impervious to liquids. Thus, they can promote healing by permitting a wound site to ~~breathe".

2Q4Q;~~~8 WO 90/11795 ~ PGT/U~90/01777 1 However, a problem can arise with semi-permeable 2 membranes when they ,are. placed over draining wounds because 3 they tend to retain fluid. For example, surgical wounds 4 often tend to drain for a post-operative period of about forty-eight hours. The fluid that can accumulate under such 6 a semi-permeable membrane during a draining period can 7 macerate the underlying tissue, cause infection and 8 otherwise inhibit healing. A procedure for alleviating this 9 problem involves periodically piercing the membrane, draining the accumulated fluids and resealing the membrane 11 opening. However, such a procedure is time-consuming for 12 health care professionals and, unless it is conducted at 13 relatively frequent intervals, can be relatively ineffective 14 in dealing with the problems associated with trapped fluid accumulation. Other procedures which involve opening or 16 changing wound dressings tend to have problems associated 17 with exposing a wound to a greater risk of infection and can 18 be uncomfortable for patients.
19 Another disadvantage with many previous wound dressings is that they are not designed to accommodate the 21 introduction of various liquid medications, such as 22 antibiotics and growth factor solutions. The application of 23 growth factor solutions may be particularly important in the 24 regeneration of skin graft donor sites.
Catheters are another type of fluidic connection system 26 with medical applications. They are commonly used for 27 withdrawing fluids from or introducing fluids to patients' 28 bodies. For example, urethral catheters are inserted into 29 the bladder through the urethra for withdrawing urine.
Typical applications for urethral catheters include patients 5 ~ ~ ~ ~ ~ ~ PCTlUS90/01777 1 who are incontinent or have otherwise lost voluntary control 2 of their bladder functions, e.g. a paraplegic with a spasdic 3 bladder condition. However, patients fitted with urethral 4 catheters are often subjected to risks of bladder and urinary tract infections.
6 To avoid some of these infection risks, condom 7 catheters have been devised which typically include a body 8 for placement over the penis and a bellows-type distal end 9 for resisting kinks and for connection to a drain tube.
However, condom catheters are susceptible to slippage and 11 can be difficult to maintain in place unless they are taped 12 to the patient's penis. Furthermore, there can be 13 difficulties in effectively draining sudden surges of urine, 14 which often back up and cause leakage problems.
Heretofore there has not been available a fluidic 16 connection system and method with the advantages and 17 features of the present invention.

19 Summary of the Invention 21 In the practice of the present invention, a fluidic 22 connection system is provided which includes a semi-23 permeable membrane including a pair of panels each having a 24 perimeter and an edge~strip. The membrane is formed by connecting the panel edge strips together to form a seam 26 extending transversely across the membrane. The panels and 27 the membrane include inner and outer surfaces. A tube 28 opening extends through the seam between the panel edge ~0~0~~8~

1 strips and between the..membrane inner and outer surfaces.
2 The membrane innervsurface is coated with an adhesive for 3 attachment to the skin of a patient.
4 A tube or sheath includes a proximate end extending through the tube opening and a distal end positioned in 6 spaced relation from the membrane outer surface. In one 7 embodiment, the tube proximate end includes a side opening 8 which is positioned in proximity to the membrane inner 9 surface. In another embodiment the tube proximate end is bifurcated by a pair of longitudinally-extending slits 11 separating a pair of tabs. A passage extends through the 12 sheath between its ends.
13 An inner conduit can be placed in the sheath passage 14 and can include a connection seal assembly for forming a fluid-tight seal with the sheath. The inner, tubular 16 conduit can be provided With a funneled proximate end for 17 using the system as a condom catheter.
18 When the fluidic connection system is used as a wound 19 dressing, an intermediate layer of material can be applied between the wound and the cover membrane inner surface.
21 Furthermore, the fluidic connection system of the present 22 invention can be used to secure a percutaneous drainage tube 23 within a patient, e.g. by inserting the percutanious tube 24 through the sheath passage.
In the practice of the method of the present invention, 26 an intermediate layer of material can be applied to a wound 27 site and the cover membrane can then be placed thereover.
28 The cover membrane can be releasably, adhesively fastened to 29 the skin around a periphery thereof. A tube fluidically communicates with the wound through an opening in the WO 90/11795 ~ ~ ~~ ~ ~ ~ ~ PCT/US90/01777 1 membrane. Fluids from a draining wound can be evacuated 2 through the tube and liquid medication and irrigation can be 3 introduced through the tube to the wound site. The fluid 4 evacuation and introduction steps of the method can each be 5 accomplished both actively and passively, and can be 6 alternated in a wound treatment procedure. Additional steps 7 that can be~included in the method of the present invention 8 include extending an inner conduit through the sheath and 9 sealing the inner conduit and the sheath together in a fluid-tight engagement.

The dressing 10 is adapted for 4 protecting and treating a variety of wounds, such as that shown at 12. y~7ithout limitation on the generality of the 6 useful applications of the present invention, the dressing 7 10 may be applied over burns, cuts, scrapes and ulcers of 8 various types, e.g. diabetic, decubitus, peripheral 9 vascular disease, venous stasis and trauma ulcers.
Skin ulcers are a common problem among many diabetics, 11 and are often brought on by poor blood circulation and nerve 12 damage associated with diabetes. The treatment of such 13 ulcers often involves grafting skin from a relatively 14 healthy donor site to an ulcerous wound site. Split thickness surgical skin graft techniques may be employed to 16 obtain skin grafts from donor sites that can then heal 17 spontaneously. Full thickness skin grafts, on the other 18 hand, generally require closure of the donor site. It will 19 be appreciated from the following description that the wound 2 0 dressing and treatment method of the present invention is 21 particularly well adapted for the protection and 22 regeneration of skin graft donor sites by providing a single 23 dressing which facilitates both fluid drainage and growth 24 factor introduction.
The wound site 12 is surrounded by healthy skin 16. A
26 fibrin layer 18 forms at the wound site 12 from fibrinogen 27 by the action of thrombin and the clotting of blood (Figs.
28 2 and 6). Surgical wounds, including those associated with skin grafts, normally drain fluid. The fluid drainage from a surgical wound is generally heaviest during a post-operative period of about forty-eight hours.
II. Wound Dressing 10 5 The wound dre~>sing 10 generally comprises a cover membrane 22 with an interior portion 24 surrounded by a perimeter 26. The membrane 22 includes a skin contact surface 28 with an adhesive coating 30. The membrane 22 preferably comprises a breathable ~~emi-permeable material characterized by 10 an ability to pass moisture vapors and an imperviousness to liquids. The adhesive coating 30 should likewise be semi-permeable. Such membrane materials are commercially available, an example being material referred to as "Tagoderm"*~ which is available from the 3M (Minnesota Mining and Manufacturing) Company of St. Paul, Minnesota. Other semi-permeable materials are available and can be successfully employed with the present invention. A protective backing 23 is placed over the adhesive coating 30 on the membrane skin contact surface 28 until the membrane 22 is ready for application.
The membrane 22 comprises a pair of panels 19 with inner, upturned edges 20 which can be adhesively joined together to form a seam 21 which extends transversely across the membrane 22 and projects generally upwardly therefrom. The panels 19 can be secured together at the seam 21 by the adhesive coating 30 to form the seam 21.
A tube or sheath 34 includes a proximate end 36 located under the :membrane 22 and a distal or free end 38. The tube 34 can be inserted through the seam 21 which forms an Trade-mark opening 32 between. the panel edge strips 20 at approximately the centre of the membrane 22. A relatively short length of the tube 34 adjacent to its proximate end 36 is shown under the membrane 22, but greater lengths of the tube 34 could be placed under the membrane 22. As shown in Fig. 4, the tube proximate end 36 is open, and adjacent to the proximate end 36 an opening is formed. Preferably the tube opening 39 projects downwardly, i.e. away from the membrane skin contact surface 28. The short length of the tube 34 which is located under the membrane 22 can be releaseably secured to the skin contact surface 28 by the adhesive coating 30, preferably with the tube opening 39 facing downwardly.
The tube 34 can comprise, for example, a flexible, plastic tube of the type that is commonly used as a protective sheath for protection of sterility for percutaneous intravenous catheter placement. Such sheaths are commercially available from Aero International, Inc. of Reading, Pennsylvania.
At its distal end 38, the tube 34 is adapted for: 1) closure with a variety of suitable closure devices: 2) connection to various active and passive fluid collection devices for draining and evacuating fluid from the wound site;
and 3) connection to various fluid source devices for actively and passively introducing fluid to the wound site.
Fig. 5 shows s bifurcated clip 240 for releaseably Closing and sealing the distal end 238 of tube 134, which is folded upon itself as shown.

WO 90/11795 ~ ~ ~ ~ ~ ~ ~ PCT/US90/01777 1 Fig. 6 shows a vacuum tube 'end 41 inserted in the tube 2 distal end 38 and secured therein by ties or ligatures 43.
3 The vacuum tube 41 fluidically communicates with a suction 4 or vacuum source 42 for actively draining fluid from the wound site. The suction or vacuum source 42 may comprise a 6 relatively simple, hand-actuated bulb or bellows, or it may 7 comprise a more sophisticated motorized pump which can be 8 actuated at predetermined time intervals or in response to 9 wound site conditions such as an accumulation of fluid under the membrane 22.
11 Fig. 7 shows an injection port 44 sealed to the tube 12 distal end 38 by a band 45. The injection port 44 includes 13 a sleeve 47 which can extend into the tube 34 to protect it 14 from needle puncture. The injection port 44 can be of the type which is designed for reuse and which automatically 16 reseals after being punctured by a syringe needle. It will 17 be appreciated that a wide variety of devices can be 18 employed for connecting the tube distal end 38 to various 19 liquid medication sources.
21 III. Treatment Plethoc7 23 According to the treatment method of the present 24 invention, the protective backing 23 is removed from the membrane contact surface 28 to expose the adhesive coating 26 30 and the membrane 22 is placed over a wound site 12 with 27 its contact surface 28 down. The membrane perimeter 26 is 28 pressed against the healthy skin 16 surrounding the wound 29 site 12 to preferably form a relatively liquid-tight adhesive bond therebetween. Various adhesive preparations WO 90/11795 ~ ~ ~ ~ ~ ~ ~ PCT/US90/01777 1 are commercially available for supplementing the bonding 2 action of the adhesive coating 30 in bonding the membrane 3 contact surface 28 to the healthy skin 16. The membranes 22 4 may be provided in various sizes to accomodate wounds of different sizes. A sufficiently large membrane 22 should 6 normally be selected to provide ample overlap of the 7 perimeter 26 over the healthy skin 16 to insure a good bond 8 therebetween.
9 The tube distal end opening 39 may be placed directly over the approximate center of the wound site 12, or it may 11 be placed eccentrically or at a depending location with 12 respect to the wound site 12. A dependent or lower position ' 13 for the opening 39 with respect to the wound site 12 may be 14 preferred to facilitate fluid drainage. The dressing ZO may be applied promptly after a wound is inflicted, e.g.
16 immediately after the graft removal procedure and a skin 17 graft operation. To reduce the risk of infection, it may be 18 advisable to promptly cover the open wound site 12. The 19 wound dressing 10 may be kept in a sterile package until it is needed. Such sterile packages and packaging techniques 21 are well known. For example, ethylene oxide may be used to 22 sterilize the dressing 10 prior to placement in a suitable 23 sterile package. The protective backing 23 is removed from 24 the membrane 22, thereby exposing its adhesive-coated contact surface 28.
26 With the membrane 22 thus secured, a chamber 46 is 27 formed between the wound site 12 and the membrane contact 28 surface 28, and is surround by the membrane perimeter 26.
29 The chamber 46 fluidically communicates with the membrane opening 32. In an evacuation mode of operation, such as 'D~~~48 .
WO 90/11795 F'GT/US90/01777 1 might be desirable for forty-eight hours or so after removal 2 of a split-thickness skin graft at a donor site, fluid 20 3 which accummulates in the chamber 46 is communicated through 4 the opening 32 and thence through the tube 34 for collection and disposal. In a passive evacuation mode of operation, 6 the fluid 20 is evacuated through capillary action, or by 7 gravity with the opening 32 at a dependent, lower location 8 in relation to the wound site 12. Such a capillary, passive 9 drainage action may be sufficient for draining the wound site 12 in many situations. Alternatively, an active 11 evacuation mode of operation involves attaching the tube 34 12 to the suction/vacuum source 42 whereby the fluid 20 is 13 positively drawn from the wound site 12 and the chamber 46.
14 Such an active evacuation mode of operation may be preferred Z5 when the dressing 10 is used in connection with a 16 hydrophilic colloidal material (hydrocolloid), as will be 17 explained in more detail hereinafter.
18 It may be desirable to operate the wound dressing 10 in 19 an introduction mode of operation whereby medications such as antibiotics and growth factor solutions are introduced to 21 the wound site 12. In this mode of operation, the tube 22 distal end 38 is connected to a liquid solution source, 23 which may comprise a syringe or any of various liquid 24 containers for passive, gravity-induced introduction.
Various adaptors, valves and injection needle ports are 26 available for fluidically coupling the tube 34 to a wide 27 variety of liquid solution sources. For example, many such 28 connectors and adaptors are available from Aero WO 90/11795 ~ ~ ~ ~ ~ ~ PCT/US90/01777 1 International, Inc. of Reading, Pennsylvania. Such 2 connecting devices are commonly used in connection with the 3 intravenous introduction of various liquid solutions.
4 In an active introduction mode of operation, solutions 5 may be pumped through the tube 34 into the chamber 46 for 6 application to the wound site 12.
7 The evacuation and introduction treatment steps can be 8 timed and sequenced as necessary to achieve the treatment 9 objectives. For example, treatment of a skin graft donor 10 site may involve fluid withdrawal a.nd drainage for about two 11 days immediately following the skin graft operation, 12 followed by treatment steps comprising the introduction of 13 antibiotics and/or growth factor solutions to the wound 14 site. The evacuation and introduction steps can be 15 alternated, and the intervals between such steps can be 16 progressively increased or decreased as necessary to 17 facilitate healing. As the wound heals, progressively 18 smaller amounts of fluid will ooze therefrom and the 19 frequency and duration of the drainage operations can be correspondingly reduced and finally discontinued altogether.
21 It will be appreciated that the wound dressing and 22 treatment method of the present invention are broadly 23 concerned with introducing fluid to wound sites and 24 evacuating fluid therefrom. The fluid introduction and evacuation procedures described herein can be performed 26 indefinitely without having to change the dressing 10. The 27 tube 34 cooperates with the membrane 22 to permit the same 28 dressing 10 to be used for both procedures, which may be WO 90/11795 2 0 ~ C~ (~ $ PCT/US90/01777 1 alternated as often as necessary. Infection risks and 2 patient discomfort can be reduced by minimizing wound 3 dressing changes.
4 The removal of toxins and bacteria from wounds is an important aspect of the fluid drainage phase of the healing 6 process. The wound dressing of the present invention 7 facilitates removal of serum and other secretions to 8 minimize the risk of infecting the wound site and macerating 9 the tissue thereat. Growth factor solutions can be important in promoting healing, and antibiotics can be 11 important in preventing and treating infection. Hence, a 12 comprehensive wound treatment can be implemented with the 13 wound dressing and treatment method of the present 14 invention.
The wound dressing 10 can be employed to irrigate a 16 wound whereby fluid is introduced and then removed.
17 The operation of the wound dressing 10 is largely a 18 matter of fluid mechanics, and the function of the wound 19 dressing l0 would probably be determined by such factors and variables as: 1) fluid viscosity; 2) permeability of the 21 membrane 22; 3) cross-sectional area of the tube 34 and the 22 area of its opening 39; 4) the integrity of the seal around 23 the membrane perimeter 26; 5) the drawing power of the 24 suction or vacuum source 42; 6) coagulation of the serum or other fluid; 7) the area of the fluid collection chamber 46;
26 8) the length of the tube 34; and 9) gravity and the 27 relative positions of various components. Naturally,.
28 varying one or more of these factors or variables could 29 change the operation of the system. It is anticipated that, applying such well-known principles of fluid mechanics, all ~~~9~~8 1 of the wound dressing components could be properly sized and 2 designed. For example, the tube opening 39 could be 3 enlarged, or multiple openings could be provided to increase 4 the rate of fluid flow into the tube 34. The rate of fluid flow can further be increased by locating the tube distal 6 end 38 at a dependent area within the chamber 46, i.e. below 7 the level of most of the wound site 12. The tube 34 can 8 extend downwardly to a collection site below the level of 9 the wound site 12 to facilitate gravity drainage.
It is further anticipated that some fluids will resist 11 drainage because of their viscosities or because they tend 12 to coagulate. Drainage of such fluids can be effected by 13 irrigating the wound site 12.

IV. first Modified Bmbodi~ment 110 17 Figure 8 shows a wound dressing 110 comprising a 18 first modified embodiment of the-present invention wherein a 19 relatively small membrane 122 is provided and functions as a patch fo.r a larger wound cover 115 with an opening 117 for 21 receiving a distal end 138 of a tube 134. The primary wound 22 cover 115 is selected to cover a wound site 112, and is 23 placed thereover in the normal fashion. The wound dressing 24 110 can be placed on the primary wound cover 115 in a location chosen to enhance fluid introduction and/or 26 evacuation. For example, to enhance the evacuation of fluid 27 by gravity, it may be desirable to form the opening 117 at a 28 relatively low position of the wound site 112. Thus, fluid 29 will tend to flow to the tube 134 by gravity. To facility the introduction and distribution of fluid, it may be desirable to locate the wound dressing 110 at a relatively high position on the wound cover 115. In fact, two or more wound dressings 110 could be placed on a single, primary wound cover 115, with a lower wound dressing 110 being provided for fluid evacuation and an upper wound dressing 110 being provided for fluid introduction.
In the practice of the treatment method of the present invention, the wound dressing 110 provides for considerable flexibility in locating the wound dressing 110 in an appropriate location on the wound site 112. After the primary wound cover 115 is positioned, the opening 117 is formed at the chosen location and the wound dressing 110 may be applied, much like a patch, with the tube distal end 138 extending through the primary wound cover opening 117. It will be appreciated that wound dressings 110 may be changed as needed without changing the primary wound cover 115.
V. Second Modified Embodiment 210 A wound dressing 210 comprising a second modified embodiment of the present invention is shown in Figs. 9 and 10 and includes an intermediate layer of material 250 between a wound site 212 and a cover membrane 222. The intermediate material layer 250 can comprise a variety of materials with varying properties such as: 1) absorbency; 2) wicking or capillary action; and 3) surface contact action. The intermediate material layer is primarily located in a chamber 246 formed between the wound 212 and the membrane 222.

WO 90/11795 ~ ~ ~ ~ ~ ~ ~ ' PGT/US90/01777 1 As a first example of an intermediate material layer 2 250, several hydrophilic colloid materials (i.e.
3 hydrocolloids) are available which would tend to absorb 4 fluids. For example, Envisan wound cleaning pads and paste are available from Marion Laboratories, Inc. of Kansas City, 6 Missouri and comprise: spherical, hydrophilic Beads of 7 Dextranomer, 0.1 to 0.3mm in diameter; polyethylene glycol 8 3000 in the pad; polyethylene glycol 600; and water QS
9 enclosed in a polyamide net bag in the pad or available in a metal foil packet for the paste. The Envisan dextraminer 11 beads function to absorb fluid and facilitate healing by 12 drawing fluid from the wound. Excess fluid can be drained 13 from the intermediate material layer 250 to prolong its 14 effectiveness. Other hydrocolloids are commercially available and may be employed with the wound dressing 210 of 16 the present invention, e.g. dextranimers available under the 17 trademark "Debrisan".
18 Alternatively, the intermediate material layer 250 can 19 comprise a mesh or sheet of synthetic material which is generally nonabsorbent and would tend to wick fluid from the 21 wound site 212 to a tube distal end 238. For example, rayon 22 available under the trademark Owens non-adherent surgical 23 dressing from the Davis & Geck division of American Cyanamid 24 Company of Danbury, Connecticut could be used to form such an intermediate material layer 250, and material available 26 from Marion Merrell Dow, Inc. of Kansas City, Missouri under 27 the trademark "Envinet " could also be employed. Such 28 materials may be referred to as "surface active", i.e.
29 promoting fibrin sealing on the wound surface. Such materials can also satisfy a capillary purpose whereby fluid ~~~~J48 1 is wicked from the wound for collection in the chamber 246 2 and ultimately for drainage. With many such materials, a 3 balance is struck,between surface action and capillary 4 action, i.e, one such function is often maximized at the 5 expense of the other. For example, Owens rayon is generally 6 considered to be relatively surface active, but may provide 7 less capillary action than other materials. Envinet mesh, 8 on the other hand, provides greater capillary action, but 9 may provide less surface action as compared to the rayon 10 material.
11 Other materials that can be used for the intermediate 12 material layer 250 include polyurethane foam and 13 polyurethane mesh.
14 The wound dressing 210 can be used according to methods 15 far use with the other wound dressings 10 and 110, and 16 includes the additional step of placing the intermediate 17 material layer 250 over the wound site 212. It will be 18 appreciated that there may be a number of materials suitable 19 for the intermediate layer 250 to achieve various 20 objectives.
21 A closure patch 251 is provided for placement over the 22 tube distal end 238 and is adapted for securing it in a 23 folded configuration to the membrane 222. The closure patch 24 251 can be used in conjunction with a bifurcated clip 240 as 2S shown in Figs. 9 and 10, and permits convenient access to 26 the tube distal end 238 for coupling it to various devices 27 such as those described herein, allowing future reuse of the 28 tube or intermittent function. Alternatively, the tube can WO 90/11795 ~ o ~~ ~ 9 ~ 8 pcauusgoiom~~
zl 1 be severed at the surface of the membrane, allowing the 2 closure patch 251 or a similar patch of the same material as 3 the wound dressing 10 to permanently seal the tube site.

YI. Third Modified 8mbodiment 3i0 7 A fluidic connection system 310 comprising a third 8 modified embodiment of the present invention is shown in 9 Figs. 11-16. Without limitation on the generality of useful applications of the fluidic connection system 310, it is 11 shown in connection with a urine collection system 312 and 12 functions as a condom catheter. The connection system 310 13 generally includes a membrane assembly 314 and a tube 14 assembly 316.
The membrane assembly 314 includes a membrane 318 with 16 an inner or skin contact surface 320, an outer surface 322, 17 a perimeter 324 and an interior portion 326. As shown in 18 Fig. 11, the membrane 318 comprises first and second panels 19 328, 330.
The panels 328, 330 include inner contact surfaces 329, 21 outer surfaces 331, perimeters 333, and edges 335 with edge 22 strips 332 which are joined together in opposing relation to 23 form a seam 334 extending transversely across the membrane 24 318 between opposite sides of its perimeter 324. A tube opening 336 extends through the seam 334 approximately in 26 the middle thereof and is open at the membrane, inner and 27 outer surfaces 320, 322.
28 An adhesive layer 338 substantially covers the membrane 29 inner surface 320 and releasably secures a two-piece protective backing 340 (e. g. paper, plastic or some other WO 90/11795 ~ ~ ~ ~ ~ ~ ~ PC'T/11C9n/~i777 1 suitable material). The backing 340 can form a transverse 2 seam 342 with a pair of unattached edge strigs 344 adapted 3 to be grasped for pulling off the backing 340. The membrane 4 318 of the fluidic connection system 310 can comprise a semi-permeable material.
6 The tube assembly 316 includes an outer tube or sheath 7 346 with proximate and distal ends 348, 350 and a passage 8 347 extending therebetween. The proximate end 348 extends 9 through the tube opening 336 and has a bifurcated configuration with a pair of longitudinally-extending, 11 opposed slits 352 forming an opposed pair of tabs 354 each 12 placed against a respective panel contact surface 320 (Fig.
13 11). The tabs 354 can be secured to the respective panel 14 inner surfaces 320 by the adhesive 338 thereon. However, for many applications of the connecting system 310 it may be 16 preferrable for the tabs 354 not to have adhesive on them.
17 The tabs 354 form a mouth 356 open at the outer tube 18 proximate end 348 and located adjacent to the membrane inner 19 surface 320. The outer tube or sheath 346 can comprise a flexible, collapsible, impervious material.
21 The tube assembly 316 also includes an inner tube or 22 conduit 358 with a proximate end 360 including a funnel 362, 23 a distal end 364, and a conduit bore 366 extending between 24 and open at the conduit ends 360 and 364.
An annular connector/seal band 372 receives the conduit 26 358 and includes enlarged-diameter end flanges 374 with a 27 reduced-diameter, annular channel or waist 376 therebetween.
28 The connector or seal band'372 can be intergally formed with 29 the conduit and thus permanently fixed in position thereon, or, alternatively, the band 372 can slideably receive the ~Ot~~~.~~
v cW2 1 conduit for adjustable repositioning. Preferrably the band 2 372, in either configuration, forms a relatively fluid-tight 3 seal on the conduit 358. The band 372, like the funnel 362, 4 can be slid through the sheath passage 347 for placement proximal to the sheath distal end 350 (Fig. 15). Belt or 6 tie means 378 can be provided for sealingly fastening the 7 sheath 346 to the band 372, ~s shown in Fig. 15, the 8 belt/tie means 378 can comprise ligatures 380, which can be 9 wrapped around the sheath 346 for tightening it against the band channel 376. Belt/tie means 378 can comprise other 11 suitable fasteners, such as strips with hook-and-loop 12 fasteners (i.e, fasteners available under the trademark 13 "Velcro"), rubber or elastic bands, plastic coated wire 14 twist ties, etc. Multiple bands 372 can be used for connecting and sealing the sheath 346 and the conduit 358.
16 The conduit distal end can project distally from the 17 sheath distal end 350 (Fig. 15) for connection to tubing 382 18 by a suitable tubing connector, such as the multi-diameter, 19 double male-ended ("Christmas Tree") connector 384 shown in Figs. 11 and 15. The tubing 382 can lead to a suitable 21 fluid collection vessel 386, which can be positioned remote 22 from the patient.

24 AII. Applications ane~ Operation 26 The fluidic connector 310 can be utilized for a variety 27 of fluidic connection applications without the inner tube or 28 conduit assembly 358. For example, the fluidic connection 29. system 310 can function as a wound dressing which operates in a manner similar to the wound dressings 10, 110 and 210 ~a~~a~~
WO 90/11795 PCTlUS90/01777 1 described above. In such applications the membrane 318 can 2 comprise a semi-permeable, plastic, film adherrent dressing 3. sheet, such as those commercially available under the trade 4 names "Op-Site", "Tagaderrn", and "Bio-Occlusive". The outer tube or sheath 346 can be utilized as a two-way conduit for 6 draining wound exudate and for introducing liguids to the 7 wound. The liquids introduced could comprise, for example, 8 aqueous solutions for irrigating the wound and growth 9 factors for promoting healing. Epidermal growth factor ("EGF") is available from Vicron. Platelet derived growth 11 factor is available from the Curatech Corporation. Such 12 growth factors can accelerate healing and re-13 epithelialization of wound sites. Without limitation on a 14 wide variety of wounds that can be treated with such dressings, they are particularly suitable for partial 16 thickness wounds, such as skin graft donor sites. Drainage 17 and liquid application can be alternated without having to 18 intermittently change the membrane 318. Frequent dressing 19 changes can be painful to skin wound patients and burdensome to health care personnel.
21 As with the previously described application~of the 22 wound dressing 110 shown in Fig. 8, the connection system 23 310 can be applied at any desired location on a larger patch 24 or membrane, and can be used in various multiple combinations, if desired. For example, one connection 26 system 310 can be used for introducing fluids, and another 27 connection system 310 can be used for draining fluids, with 28 both connection systems 310 operating simultaneously if 29 desired.

WO 90/11795 ~ ~ ~~ ~ ~ ~a ~ PCT/U590/01777 1 To promote efficient drainage, the connection system 2 310 can be located at a dependent part of a larger dressing.
3 Alternatively, mechanical suction equipment can be connected 4 for promoting drainage.
5 Another application of the fluidic connection system 6 310 is placement over percutaneous catheters, drain tubes, 7 etc. Such tubes present infection risks where they 8 penetrate the skin surface, and can require frequent 9 application of antibiotics to reduce the risk of infection.
10 Percutaneous tubes are often sutured in place at the stab 11 wound locations where they penetrate the skin, and the 12 sutures are further susceptible to infection and can cause 13 swelling and patient irritation. The connection system 310 14 can be placed over such a percutaneous drain tube or 15 catheter site, with the tubing extending through the sheath 16 346 in the manner of the conduit 358. The tubing can be 17 secured, for example with one or more bands 372, to protect 18 against traction forces which might otherwise tend to pull 19 the tubing loose. By utilizing a semi-permeable, breathable 20 material for the membrane 318, the skin surrounding a 21 percutanious tubing entry site can be protected against 22 maceation.
23 For use as a condom catheter in a urine collection 24 system 312, the backing 340 can be removed from the first 25 panel 328, which is then adhesively secured to the ventral 26 side 389 and the lateral sides 391 of a flaccid penis 388 27 with the urethra orifice or meatus 390 directed at the 28 sheath mouth 356 and the sheath tabs 354 placed on the top 29 and bottom of the glens or penile head 392 (Fig. 13). The PG.'T/US90/01777 1 second panel 330, with the backing 340 removed', can then be 2 adhered to the penile dorsal side 394 and to the first 3 panel 328.
4 The procedure described above provides a relatively secure attachment of the connection system 310 to the penis 6 388, since the penile shaft 396 and the.penile head 392 7 provide substantial areas of attachment. The attachment can 8 further be enhanced by prestretching the flaccid penis to 9 provide maximum contact area.
The connection system 310 described above can be 11 utilized as a complete condom catheter by fluidically 12 connecting the sheath distal end 350 to a suitable urine 13 vessel, for example with a band such as that shown at 45 in 14 Fig. 7. Alternatively, the inner tube or conduit 358 can then be inserted through the sheath passage 347 in its open, 16 distal end 350. The Funnel 362 can be placed against the 17 plans 392 over the meatus 390, and can be secured in this 18 position by fastening the sheath 346 to the band 372 with 19 the sheath 346 slightly in tension and the conduit 358 slightly in compression. The funnel 362 can comprise a 21 moldable plastic material, and its end can be rolled or 22 flanged as shown in Fig. 14 for patient comfort. However, 23 in operation the funnel 362 is not required to form a fluid-24 tight seal with the plans 392, and it is anticipated that the funnel 362 may slip distally away from the plans 392.
26 The funnel 362 cooperates with the connection system 310 to 27 direct a surge of urine into the conduit 358. Urine which 28 escapes the funnel 362 can collect in an interstitial space 29 397 between the sheath 346, the conduit 358, the plans 392 and the band 372. Urine in the interstitial space 397 ran WO 90/11795 ~ ~ L~ ~ ~ L~ $ PCT/US90/01777 1 drain to the funnel 362 for evacuation through the conduit 2 358.
