COLOSTOMY OR ILEOSTOMY APPLIANCE Filed Feb. 11, 1957 3 Sheets-Sheet 3 United States Patent C) 3,006,343 COLOSTOMY OR ILEOSTOMY APPLIANCE Thomas R. Baxter, 202 N. Edgewood Road, Mount Vernon, Ohio Filed Feb. 11, 1957, Ser. No. 639,277 11 Claims. (Cl. 12S-283) The present invention relates to colostomy or ileostomy devices of the type wherein a ring structure is supported on persons abdomen by suitable supporting harness and is employed for temporary support thereon of a disposable bag for receiving intestinal or ileal discharge from an abdominal opening surrounded by the ring structure, and is an improvement upon the surgical appliance of my prior Patent No. 2,581,319 of January 1, 1952.

A general object of the present invention is to provide in such an appliance a ring structure which is suiliciently pliable or exible as to be readily conformable to the abdominal contours when clamped thereto and which after a period of usage takes a physical set in shape dictated by such contours thereby assuring maximum comfort to the wearer, which is readily manipulated to secure such bag thereto in a leak-proof manner and which is of simple and economical construction.

A more specific object of the present invention is to provide in such an appliance a disposable bag-supporting ring structure which is formed from or includes a semirigid annulus or washer-like ring of ilexible elastic plastic material that conforms to the contours of an area of a persons abdomen when clamped thereto and in use under the influence of body heat and clamping stress takes a physical set to a shape corresponding generally to the shape of the body portion over which it is clamped to assure maximum comfort to the wearer.

Another object of the present invention is to provide an embodiment of the invention in which the annulus is in the form of -a stack of washer-like plies secured together, one or more of which is formed fromtheV settable elastic plastic and another of which is formed from ilexible rubber-like material to assure a certain flexibility of the annulus and to tendency of the latter to buckle and unduly bow laterally under considerable strain applied by fastening or supporting harness strapped to the body at points across on opposite sides thereof, i.e., harness strain in opposite directions generally in the plane of the annulus.

`A further object of the invention is to provide an embodiment of the invention which is particularly adapted for use as an ileostomy appliance with the bagsupport ing annulus or ring being faced on one side; with a permanently tacky material which will securely hold the ring temporarily to the body skin in a fluid-tight manner when the ring is clamped thereto while permitting ready peel-away without stripping the stratum corneum, thereby effectively avoiding irritating digestion of the lskin about the stoma by the active digestive fluids discharged and a stripping of the skin upon removal of the appliance for change of the disposable bag.

Still another object of the invention is the provision of structural embodiments of the appliance which may be readily constructed and whichrwill permit ecient use and operation thereof.

Other objects of the invention will in part be obvious and will in part appear hereinafter.

The invention accordingly comprises the features of construction, combination of elements, and arrangement of parts, which will be'exemplified in the constructions hereinafter set forth, and the scope of the invention will be indicated in the claims.

For a fuller understanding of the nature and objects of the invention reference should be had to the following rice detailed description taken in connection with the accompanying drawings, in which: l

rIhe ring structures of the embodiments of the invention illustrated in the drawings, by way of example, all are characterized by a degree' of flexibility permitting each when worn readily to conform to the contours of that portion of the persons abdomen over which it is strapped by suitable supporting harness. However, each ring structure is semi-rigid or is of such rigidity that when anchored at diametrically opposite points to supporting harness, as may be preferred, pulling or clamping stress applied at such points will not unduly buckle the ring structure intermediate the anchoring points to defeat the t attained by conformance to abdominal contours. Further, each ring structure is formed from or embodies one or more plies of synthetic polymerized or elastic plastic material of a character which in use lfor an appreciable period of time under the influence of 'body heat, which normally is at a temperature of about 37C., and clamping stress will take a physical set to the contour-conforming shape corresponding generally to the shape of the body portion over which it is clamped, in order to assure maximum comfort tothe wearer and leak-proof attachment of the appliance at all times. Such t as is provided by the contour-conforming shape has been found to assure an efficient leak-proof mount of the supported bag to the patients abdomen. This physical setting characteristic is exhibited by a variety kof types -of elastic plastic materials, such as, for example, certain polyethylenes; vinylidene chloride resin polymers or copolymers, frequently referred to by the trade name Saran; and ilexible polystyrenes. The polyethylenes wh-ich are molded o r cast from resins produced in reactors under relatively high pressure (and thus called high pressure polyethylenes) are, as a rule, softer and less rigid than low pressure polyethylenes. Such high pressure polyethylenes may be preferred from the standpoint of comfort although more likely to buckle and unduly distort at intermediate top and bottom points under pulling or clamping stress applied at remote side points. As hereinafter indicated suitable provision may be made to overcome the latter diiicu-lty. Some low pressure polyethylene materials may have sufficient stiness to be suitable for this service, e.g. Marlex 50 produced by the Phillips Petroleum Co. The softness of the polyethylene ring structure may be increased for assuring greater comfort without causing it to be too prone to buckling and undue distortion by incorporating with the resin about to 25% of butyl rubber or about 3% to 10% of polyisobutylene, or in a plural-ply ring structure one or more intervening or associated plies may be formed or rubber-like or synthetic rubber material, such as butyl rub-ber, as will be explained later.

Referring t-o the drawings, like numerals identify similar parts throughout the various embodiments illustrated therein by way of example. It will be seen therefrom and, more particularly, from FIGS. l'to 5 inclusive that an embodiment of the present invention may comprise a ring structure suitably anchored or fastened to supporting harness or a waist-encircling 4belt 21 by harnessengaging means-which may comprise headed studs or buttons 22, 22 carried by the ring structure and over which are clipped fastener loops 23, 23 suitably secured to the opposed ends of the belt. A linking tie or tethering strap 24, which maybe elastic to permit an amount of stretching to facilitate donning of the belt 21, may be fastened, detachably if desired, to the fastener loops 23, 23 to retain the belt in position about the wearers waist -when the bag supporting-ring structure is detached from the belt for bag replacement. The .bag 25 is of the disposable tubular type made of flaccid waterproof material, such as substantially 'duid impervious polyethylene composition, Pliolm, a vinyl or the like, having an open end ora relatively wide open mouth dened by a free marginal portion 26 of the bag walls.

Referring to the embodiment illustrated in FIGS. l to 5 inclusive, it will be seen that the ring structure 20 may be provided as asemi-rigid annulus preferably washer-like in form of relatively wide llexible stock having appreciable thickness while beingl appreciably greaterV in width than/the thickness and initially having a substantially flat bearing face 27. The annulus 20 may be cut out by a suitable die from a sheet of flexible, relatively hard, semi-rigid polyethylene sheet having a thickness of about one-eighth of* an inch, an O.D. of about three and one-fourth inches, and an LD. of about two and threeeighths inches. The parts of the anchoring means or harness-engaging means at 22, 22 may each be provided in the form of a headed aluminum or stainless steel pin or button having an enlarged head 28 and a stepped shank 29 with a portion 129 of the latter of smaller diameter received through a hole in the annulus 20 and with the back end thereof spun over, as is indicated at 30 in FIG. 4. It will be seen therefrom that the shank 29 of each headed button or pin 22 is appreciably longer than the thickness of the annulus 20 so that the clip loop 23 may be snapped thereabout between its head 28 and the outer face 31 of the annulus. Although two headed pins 22, 22 located across the ring to opposite sides thereof are shown .for anchoring support by suitable harness it is to be understood that each such means may consist of a pair thereof with the two of each pair located a relatively short distance apart and with the two pairs located across the ring from each other.

VIn order to support bag 25 from the annulus 20 of the FIGS. l to 5 inclusive embodiment -in a fluid-tight manner, the open end 26 of the bag is drawn through the annulus hole 32 from the outer side thereof and is then wrapped in one or more turns about the annulus, covering the pin heads 2.8, 28 with one or more layers of bag material, as will be seen from FIG. 2. Then with the belt 21 encircling the wearers Waist, theclip loops 23, 23 are snapped over the covered pin heads 28, 28 and the ring structure -with the bag mouth anchored'to and supported thereby adjusted about the stoma depicted at 33, as illustrated in FIG. 2.

A plurality of turns of the free end 26 of the bag 25 may be wrapped around ther-ing structure 20 in a manner similar to that proposed in FIGS. 9 to l2. inclusive. FIG. 9 illustrates drawing of the openend 26 of the bag 25 through the ring structure 20 from the outer side thereof in the direction of the arrow 34, and FIG. l0 illustrates yan initial ylap back of the edge of the bag mouth in the direction of the arrows 35, 35. In FIG. 10 yis also illustrated initial manipulation of a portion of the annulus 20 intermediate the .headed pins 22, 22 in the direction of the arrow 36, to turn the annulus in through itself `and thereby wrap the bag mouth thereabout. In order more readily to understand lshis turn-through and wrap of the annulus 20, reference should be made to FIG. ll wherein is illustrated by arrow 36 turn-through of one half of the annulusV 29 and then a reversal of the annulus and bag so that one is looking down into the open mountV of the bag. The ot-herhalf of the annulus 20 will then be turned through in the direction of the arrow 136 to complete the turn-through of the annulus and the lattainment of the wrap approaching two full turns of the bag mouth thereabout to complete the suppont or anchorage of the bag 25 illustrated in FIG. l2.

It will thus be understood from FIGS. 9 to l2 inclusive that although the ring structure 20 must have appreciable rigidity `it must likewise retain a fair degree of flexibility so as to permit the illustrated turn-through in wrapping the mouth of each bag 25 thereabout in the change of the bags. Also, as illustrated in FIG. 2, elasticity of the `annulus 20 rnust be such as to permit the ring to conformy to the abdominalv contours for close t thereof, and of the turns of the bag mouth 26 wrapped thereabout, to the abdominal wall. Additionally, after a period of use under the influence of body heat and strain applied by clamping stress, the annulus 20 is to take a permanent physical set to a shape, such as that illustrated in FIG. 5, so as comfortably to lit against the abdomen when reapplied.

'I'he demand of some wearers may require greater flexibility of the ring structure for maximum conn?v ort with respect to a particularly selected elastic plastic material. One cannot materially reduce the thickness of the ring structure since, in the preferred form, clamping stress is to be applied at points across on opposite sides of the ring by anchorage means which will tend sharply to buckle outward portions of the annulus at bottom and top opposite points intermediate the locations of the anchorage means when the annulus is excessively thin. Headed pins, such as those shown at 22, 22, are preferred as such anchor-age means lbecause of the simplicity thereof, the accessibility thereof with respect to anchoring clips on the supporting harness and their functions of connecting plies together thereat. When such pins are employed the strain of harness stress is applied to the ring structure as levering strain through the pin Shanks which in turn transmits leverage along the ring structure to remote intermedi-ate points to tend there to develop buckling. Forming the ring structure properly overcomes this tendency, as explained hereinafter. Such increased flexibility may be attained in embodiments of the invention employing such anchorage means by forming the ring structure asfa plurality of or stack of washerlike plies, such `as is proposed in FIG. 6. In the FIG. 6 structure two plies or flat rings 120, 120 are secured together by the headed anchoring pins 22, 22 in face-to face relation at diametrically opposite points across the ring structure from each other. Such plural-ply ring structure is satisfactory when the plies are formed from relatively rigid elastic plastic material, such as relatively hard polyethylene, but if more exible plastic material is employed for such a plural-ply ring structure it may be suitably stitfened by securing the plies together along their outer circumferential edges while being free from each other along their inner circumferential edges and substantially over their juxtaposed faces, as is proposed in FIG. 7, the plies being secured together annularly as indicated at 37'by any suitable means, such as cement or heat-sealing. Tendency to buckle at bottom and top points intermediate the headed pins, such as those shown at 22, 22, where clamping stress is concentrated is reduced by such lannular securement, such as that proposed at 37 in FIG. 7, and more so if -the plies are secured together in face-to-f-ace engagement, such as by interposed cement. 1 It has been found that increased iiexibility may be assured while avoiding such a tendency for intermediate top and bottom outward buckling by increasing the mass of the ring structure with relatively highly flexible material, such as by intervening two of the elastic Vplastic plies with a more highly exible ply. For example, as proposed in FIG. 8 a pair of elastic plastic plies 220, 220 f polyethylene, each of which may be about three sixtyfourths of an inch thick, if desired, may be intervened by a ply 38 of synthetic rubber compound, such as gum rubber composition, having a durometer of about 4 to 20 dependingupon the exibility desired and which, if desired, may be about three thirty-seconds of an inch thick. The juxtaposed faces of the plies 220, 38 and 220 may be suitably cemented together, such as by rubber cement, and the flexibility may be controlled both by the selected thicknesses of the plies and the particular durometer of the interposed rubber compound ply 38. A relatively low durometer intervening rubber ply is employed for a relatively small ring structure while a somewhat larger diameter ring structure may require a harder rubber ply due to the fact that in the larger ring structures a greater degree of manipulation is assured by the greater leverage provided 'by the increased dimensions of the parts. When a plurality or stack of plies are employed to construct the ring structure and it is desired to secure them in face-toface engagement they may be suitably cemented together but if thermoplastic materials are selected for their formation, heat-sealing may be employed for this purpose. Embodiments of 'the ring structure of the present inf vention may be `designed for use particularly as ileostomy appliances. Since the performance of an ileostomy usually involves removal of more of the lower bowel and at times a part of the upper bowl, drainage from the stoma will include active digestive uids which can digest the skin around the stoma. Thus it is imperative in such cases to assure a careful huid-tight tit between'the appliance and the skin. The contour fitting as assured by the physically set ring structure of the present invention should be suicient for this purpose but some patients require for 'peace of mind a more visibly demonstrated 6 type of sealing to the abdomen. It has been previously proposed to seal ring structure to the abdominal Wall by the use of certain cements which, however, have not been entirely successful since they tend to canse stripping of the stratum corneum with peel-away of the ring structure and, of course, the inner lface of the latter must be exposed for adherent engagement to the skin. An embodiment of the present invention well designed for use `as such an lileostomy appliance is shown in FIGS. 13 to 16 inclusive.

The ring structure of the FIGS. 13 to 16 inclusive embodiment may comprise an inner Washer-like ring or annulus 320 to be formed from the elastic plastic material and carrying headed studs 122, 122 lat diametrically opposite points. Means is provided to secure in a fluidtight manner the open mouth of the disposable bag 25 to the outer face 131 of the annulus 320. Such means preferably is in the form of a flexible clamping ring 39 having enlarged holes 40, 40 extending therethrough at diametrically opposite points freely to receive therethrough the heads 128, 128 of the yanchoring pins 122, 122.

As is illustrated in FIG. 15, the disposable bag 25 may have its open end 26 anchored to the washer-like ring 320 by being pulled through the clamping ring 39 from the outer side thereof in the direction of the arrow 41 and then lapped aboutv and reversed in the direction of the arrow 42 to provide a skirt surrounding the bag and depending from the clamping ring, as will be seen in the lower portion of FIG. 15. Thereafter the heads 128, 128 of the pins 122', 122 will be aligned with the holes 40, 40 covered by bag mouth material. Then the ring 320 will be pushed forward in the direction of arrows 43, 43 to- Ward the ring 39 so that the pin heads 128, 12S will push bag mouth material through the holes 40, 40 with the covered heads of the pins eventually extending appreciably beyond the clamping ring 39 to receive the belt clamping loops 23, 23, as indicated in FIG. 14, thereby clamping between the rings in Fluid-tight manner the walls Y of the open mouth of the bag; It will -thus be seen that pins 122, 122, carried by the inner Washer-like ring 320, serve as means temporarily, anchoring the rexible clamping ring 39 to the outer face of the former. The heads 128, 128 of the pins 122, 122 on ring 320 are pushed through holes 40, 40 in ring 39 for this purpose, so as to clamp between the rings in Huid-tight manner the wall 26 of the open mouth of the disposable bag 25 after its open end had been pulled through and lapped about the clamping ring 39, as is illustrated in FIG. l5. The body encircling harness means may be in the form of belt 21, as is previously indicated, carrying at the ends thereof Vfastener or clamping loops 23, 23. The heads 128, 128 of pins 122, 122 whether covered or not by bag mouth Wall material, serve removably to receive the clamping loops 23, 23, and since these pins are mounted to the outer side of ring 320 they constitute anchoring means for the harness means which are mounted to the outer face of this washer-like ring. Thus pins 122, 122 and their heads serve the dual purpose of cooperating with structure of clamping yring 39 temporarily to clamp the latter to the outer face of the washer-like ring 320 to secure the bag mouth therebetween, and also as means to anchor the harness to the outer face of the washer-like ring.

It has been found in the developmentof' the embodiment ofthe invention illustrated in FIGS. 13 -to 16 inclusive that the inner face of the ring 320 may be adhered to the abdominal skin in a duid-tight manner by unique means which may be in the form of a permanently tacky Vfacing or thin ring 44, which will securely adhere to the skin under clamping pressure of the harness while being readily peeled away without danger of stripping the stratum corneum. For this purpose the adhering ring or facing 44 may be formed of tacky polypropylene or tacky polyethylene compound secured to the inner face 127 of the ring 320 by any suitable means, such as a layer of cement 45, and such facing orl adhering ring may, for

example, be of a thickness of about 0.004". The tacky layer 44 may be of a thickness of about 4 to 8 mils, if desired. In order to make polyethylene tacky for this purpose it can be compounded with suitable additives and extruded at relatively high temperatures. Such tacky polyethylene compound may be made by milling together polyethylene resin, about l to 15% rubber and about l0 to 15% mineral oil, and then extruding the mixture at relatively high temperature of the order of about 575 F. Any other permanently tacky plastic material may be employed for this purpose provided it is resistant to attack by the digestive fluids and is chemically inert with respect to body moisture and the discharged iluids. FIGS. 13 and 14 illustrate adherent securement of the ring structure `directly to the abdominal skin by the tacky facing 43 with the ring structure conforming to the abdominal contours. After a period of use, the ring structure of the FIGS. 13, 14 and 15 embodiment become physically set to substantial conformance with the abdominal contours, as explained above. FIG. 16 indicates by a showing to greatly increased scale that the back ends of the reduced Shanks of the headed pins 122 preferably are spun over with suilicient pressure as to cause the spun enlargement 130 of each actually to sink into the elastic plastic of ring 320 so that the back end of the pin is substantially flush with the inner face of the ring. This permits efective covering of the back ends 13G, 130 of pins 122, 122 by the tacky layer 44 when cemented thereover by the layer of cement 45.

'It will thus be seen that the objects set forth above, among those made apparent from the preceding description, are efficiently attained and, since certain changes may be made in the above construction without departing from the scope of the invention, it is intended that all matter contained in therabove description or shown in the accompanying drawings shall be interpreted as illustrative and not in a limiting sense.

It is also to be understood that the following claims are intended to cover all of the generic and specic features of the invention herein described, and all statements of the scope of the invention which, as a matter of language, might be said to fall therebetween.
