ATTaR/v EY ANAESTIIESIOLOGY DRAPING SCREEN STRUCTURE My invention relates to an anaesthesiology screen structure. More particularly, my invention relates to such a screen structure comprising a first draping cloth screen and a second sterile screen, and supporting means therefor.
To minimize complications which may result from airborne germs present during surgery, the surgeon and his aides are scrubbed," wear sterile clothes, and face masks. Also, the instruments and other physical equipment present are sterile. Despite what may be done so far as sterile conditions for the surgical personnel and equipment, there remains the lack of sterility because of contamination through contact with nonsterile material and personnel necessarily in close proximity to the patient. Thus, it has become common to use an anaesthesiology draping cloth screen and to isolate the.
proximity to the surgical'area, is extremely crowded as we will I have generally present the operating surgeon and his assistant as well as other personnel, as nurses. for example. While-the hands of the operating surgeon will be directly'involvedin a surgical area, nevertheless, everyone who is handing him articles and instruments or aiding him is also positioned adjacent the surgical area, and thus a very physically crowded I area is involved. Obviously, elbows and other parts of thebodies of "the surgical team will many times contact the sterile' drapes which are the usual anaesthesiology draping cloth screen during the operation. Such contact between such portions of the bodies of members of the surgical team andthe said drapes may lead to contamination of the .team if the drapes are accidentally touched by nonsterile personnel from the anaesthesiologists side of the screen.
It is an object of my invention to provide an anaesthesiology screen structure comprising first and second screens, the. first of which supports a draping cloth screenextending crosswise of the surgical table and at the level just caudad to the head of the patient so that such transversely extendingsereen provides for two areas isolated from each other, one for the head of thepatient as well as the anaesthesiologist and his personnel and equipment and the second for the surgical area and'for the surgeon and his personnel and equipment. The second anaesthesiology screen is I characterized by extending crosswise of the surgical table, parallel to the-first screen, disposed at a higher elevationthan the first screen, formed of a' rigid transparent material, such'as Plexiglass or methyl methacrylate and protects sterile drapes laid across the first screen from contamination by personnel at the head of the operating table.
Other objects are to provide an anaesthesiologyscreen structure comprising two base supports which are disposed on opposite sides of a surgical table and which base supports each carries a vertical support. The said vertical supports carryformed of a plurality of hinged together panels, as three, and:
tosecure'the side panels-of such second screen'to spaced supports so that all of the panels, when inus'e, will'form a continuous rigid panel but which may i be folded when disassembled for compact storage and to enable the unit to be placed in the surgical sterilizer before use.
Other more specific objects are to provide supports for said second screen which are detachable from the supports for the first screen and which are vertically adjustable relative to the supports for the first screen.
Other objectsof my invention will become apparent or implicit as the description of my invention proceeds in connection with the drawings, throughout which like reference numerals refer to like parts, and wherein:
FIG. 1 is a fragmentary view in side elevation showing a surgical. table, a patient thereon and a first draping cloth screen in place between the head and the torso of the patient;
FIG. 2 is a fragmentary perspective view of the showing of FIG. I and showing in addition a second anaesthesiology sterile-screen of my invention in applied position;
FIG. 3 is a fragmentary perspective view of one of the supporting means for supporting the second anaesthesiology sterile screen;
FIG. 4 is a plan view of parts shown in FIG. 3; and
FIG. 5 is a perspective :view of the second anaesthesiology sterile screen shown detached and with the panels thereofin folded position so as to be easily placed in the surgical sterilizer.
A conventional surgical table 10 (FIGS. l and 2) is provided with a base support 12 on each: side .thereof. Attached to each base support 12 is a first vertical'support-'l4. As indicated in connection with FIGS. 1 and 2, the base support 12 may include a sleeve portion to detachably receive a generally horizontal portion 16 of the support 14. Thus, by the use of a wingnut 18; the horizontal portion-l6 may be loosened relative to the base support 12 for removal or the.
wingnut 18 .may be tightened and the portion 16 rigidly secured to thebase support 12., It isdesirable to havereach. vertical support 14 detachablyconnected with the surgical table 10 for convenience of use and convenience of removal or installation when desired.
The first vertical supports l4- (see'. FIG. 2) are interconnected by a crosswise horizontally extending support 20. Also, each vertical support 14 7 preferably supports .a winglike outwardly-extending arm 22. The supports 14, cross supportss20, and arms 22.support a draping anaesthesiology cloth 24 which is draped crosswise of the surgical table and at a level caudad to the head of the patient, all in accordance with established practices. Also, tape and skin. clips, in accordance with conventional practices may be employed to provide a relatively tight fit between thesurgical cloth 24 and the skin of the patient at the neck and shoulder areas.
The verticalsupports 14 preferably also support the second anaesthesiology sterile screen. Preferably, the said first vertical supports I4 are tubular in section and a split sleeve structure (see FIG. 3) is employed to detachably connect the supporting structure forthe second L anaesthesiology sterile screen with said first vertical supports 14. This split sleeve construction comprises a half sleeve 26'rigidly secured 'to a plate 28 astby welding. A second half sleeve 30 is hinged to the first half sleeve 28.-by hinge means 32.(see FIG. 4). A sleeve 34 is hinged to second half sleeve 30 and sleeve 34 threadedly receives threaded .pin 36. As sleeve 34 is pivotally connected with a sleeve 30,'the said pin 36 may be turned to the position shown-in FIG. 3 of the drawings or saidpin may be-turned. approximately to the position shown in FIG. 4 of the drawings and with the pin 36'extending through the slot 38 in plate 28. The threaded pin 36 terminates in a head portion 40. Upon loosening of the threaded pin 36,- the two half-sleeves 26 and 30 may be separated as indicated in FIG. 3 of the drawings or they may be moved into closed position as indicated in FIG. 4 of the drawings so that the said half-sleeves 26'and 30 and parts carried. thereby may be connected with the vertical supports 14 as indicated in FIG. 2 of the drawings.
Eachplate 28 is .pivotally connected to a bracket 42, as by nut-and-bolt means 44. A means for maintaining-an adjusted;
turned position of abracket 42 relative to aplate 28 may be in movable into selected registration with a hole in a bracket 421- When such holes are in a line, then a pin means 48 may be inserted through registering holes and an adjustment thus obtained may be maintained. For convenience a keeper chain 50 will maintain the pin means 48 in close proximity to the holes 46.
Each bracket 42 comprises an angular portion which terminates in a vertical portion 52. The second anaesthesiology sterile screen comprises a central panel 54 and two side panels 56. Preferably, said panels 54 and 56 are rigid and transparent panels and thus may be formed of any suitable material, such as Plexiglass or methyl methacrylate. Such material readily provides for desired rigidity as well as transparency. Also, such material may be sterilized in a manner customary for sterilizing surgical instruments, and thus safely touched by the surgical team on one side without fear of contamination. The vertical portion 52 of each bracket 42 is connected with a side panel 56 as by nut-and-bolt means 58. By connecting the vertical portion 52 of each bracket 42 to the side panels 56, then the panels 56, 54, 56 are held as a rigid unit during use but upon detachment of the unit from the vertical supports 14, then the entire second anaesthesiology sterile screen and its supporting structure can be readily folded for compact storage as indicated in FIG. 5 of the drawings and also for sterilization in commercially available sterilization equipment. Also, in view of the fact that the vertical portions 52 of the brackets 42 are vertically adjustable through the pin means 48 and holes 46, the end result is that the second anaesthesiology sterile screen is adjustable vertically relative to the surgical table 10. This will allow for a desired elevation of the said second screen as may be required depending upon the size of a patient, convenience of personnel, and the like.
During operations on the chest and in areas relatively close to the anaesthesiology cloth 24, there will be generally two doctors in close proximity to the surgical area and also nurses or other aides in close proximity to the surgical area. Thus, the area close to the anaesthesiology draping cloth 24 will be a highly congested area and there will be quite a number of arms and portions of the bodies of the surgeon and his aides and assistants so that, in the past there was considerable personnel and clothing contact with the anaesthesiology cloth, similar to the cloth 24. At times it was thought desirable to make the cloth 24 of a height so it could not be pushed downwardly and worked over" by the elbows of the surgeon and his attending personnel. However, such structure was not practical as it obstructed the view of the anaesthesiologist who necessarily must be able to see the surgery. On the other hand, the second anesthesiology sterile screen comprising the panels 56, 54, 56, may be of any desired height and any desired rigidity so that the sterile first anaesthesiology draping cloth screen will not be contaminated by the nonsterile personnel at the head of the operating table. By having the said second anaesthesiologist screen transparent, the anaesthesiologist, who is operating on the patients head side of the said second anaesthesiologist screen, can readily coordinate his activities to those of the attending surgeon.
From the foregoing, it will now be apparent that l have provided an anaesthesiology draping structure comprising two spaced-apart base supports 12 which are adapted to be supported by opposite sides of a surgical table. These base supports 12 preferably detachably support first vertical supports 14 disposed on opposite sides of the table. These vertical supports 14 in turn support structure comprising cross support and winglike arms 22 which will support a first anaesthesiology draping cloth screen 24. This first draping cloth screen 24 may be at a lower level in elevation as there will be other supports and a second anaesthesiology sterile screen to protect the head of the patient and to protect the first draping cloth screen 24 from contamination by the nonsterile personnel.
Other details of my invention which will now be apparent are that the second anaesthesiology sterile screen 56, 54, 56 is supported by two spaced-apart second vertical supports 26,
28, 30, 42, 52, and each of said second vertical supports is detachably connected to a first vertical support 14. The said second anaesthesiologist sterile screen 56, 54, 56 is disposed toward the head end of. the surgical table relative to the position of the first draping cloth screen 24 and the said second sterile screen is at a higher elevation than the first draping cloth screen 24 and any desired height is practical in view of the fact that the said second sterile screen is transparent and is rigidly supported by the surgical table 10. For convenience in storage and sterilization and the desired rigidity when in use, the said second sterile screen comprises a central panel 54 and two side panels 56, each of the latter being hinged to a marginal side edge portion of the central panel 54 and the vertical uprights, including the vertical portion 52, are secured to side panels 56, as by nut-and-bolt means 58. Other details of my invention have been described or any inherent in the description and illustrations herein and within the scope of the aPpended claims.
