POST-OPERATIVE BANDAGE Filed March 25, 1950 INVENTOR 561M578 BY a ATT NEY Patented July 15, 1952 UNITED STATES PATENT OFFICE POST-OPERATIVE BANDAGE Edmund F. Buryan, Westchester County, N. Y.

Application March 25, 1950, Serial No. 151,915

The present invention relates to a special bandage designed particularly for post-operative use following surgery in the anus or vagina.

Insofar as I am aware, there is no fully satisfactory bandage suitable or especially adapted for use after hemorrhoidectomies and other operations and which are insertable into, and removable from, body cavities without a great deal of discomfort and other disadvantageous effect.

It is, therefore, an object of this invention to provide for the first time a special construction of bandage which overcomes the drawbacks mentioned above and which has new features and characteristics not heretofore available.

Another object of the invention resides in the provision of a tubular or cylindrical bandage in which one portion is drawn through another so as to provide, in effect, a double bandage which can be withdrawn from a body cavity while decreasing its diameter thereby facilitating removal and avoiding pain and disturbance of healing incisions or the like.

A further object of the invention resides in a bandage of the character referred to which is impregnated and/or coated with special substances for therapeutic and antiseptic purposes.

Other and further objects and advantages will be understood and appreciated by those skilled in this art or will be apparent or pointed out hereinafter.

In the accompanying drawing wherein I have illustrated a preferred embodiment of the invention:

Figure 1 is a perspective view of a bandage responding to my invention;

Figure 2 is a longitudinal medial section through Figure 1 and Figure 3 is an end view looking from right to left in Figure 1.

Referring now to my bandage in detail in conjunction with the drawing, numeral indicates a tubular or cylindrical outer portion which, as will be appreciated from Figure 2, merges with and forms a part of a similarly shaped inner bandage portion ll. As shown in the drawings, the outer bandage portion In is inturned at one end and drawn through itself so as to form a double or composite bandage having the structure and arrangement which is clear from Figure 2. This can readily be accomplished by forming a tubular bandage of the desired external dimensions and then somewhat compressing one end thereof and drawing it through the opening I2 until it projects slightly therefrom to provide a terminal portion which can be read- 5 Claims. (Cl. 128-156) ily grasped by hand or by forceps for the purpose to be hereinafter described. The inner bandage portion ll becomes reduced in diameter and its central openings l3 becomes a channel'or passageway, which has various uses, such as for drainage, for the insertion of a speculum, other instruments, etc.

The material of the bandage is preferably an absorbent cotton or other soft, pliant, cellulosic material such as cellucotton, gauze, absorbent paper and the like. The material of the bandage must be soft enough to avoid injury and yet have enough body to substantially retain its shape during use. It also must be sterilizable without undue deterioration. It is, of course, discarded after a single use.

In addition, the bandage material may be impregnated and/or coated with a variety of substances for special purposes; for example, to retard absorption and consequent coagulation of blood within the fibrous bandage material, the surfaces thereof are impregnated or coated with a plastic base material or shellac, which provides a smooth but flexible semi-impervious or impervious surface. A similar effect is obtained by surfacing the bandage material with cellophane or other similar material. Particular therapeutic and analeptic results can be produced by providing the bandage material with a thin, outer layer of fibrin film or fibrin foam and the bandage may furthermore be rendered bacteriostatic or bactericidal by impregnation with an antibiotic or other chemo-therapeutic agent such as sulfonamide, penicillin, streptomycin or a quaternary ammonium compound, such as an alkyldimethyl-benzyl-ammonium chloride. Various combinations of bacteriostatic and bactericidal agents may also be employed. In a further form of the invention, the bandage material is coated on those surfaces which come into contact with one another with a lubricant such as a mineral or vegetable, natural or synthetic oil, fat or wax, or other innocuous material having lubricating properties.

In use, a bandage constructed in accordance with the present invention and as illustrated in Figure 1 is inserted into the body cavity at the appropriate time and allowed to remain therein until the physician, attendant or technician desires to have it removed, at which time the projecting end of the inner portion l l of the bandage is grasped with the fingers or by means of forceps or other suitable instrument and gradually and steadily pulled out. This action causes the opposite end of the bandage to be somewhat Particularly in connection with the removal of my new bandage from the anal canal subsequent to a hemorrhoidectomy, my bandage finds par ticular utility and application. Under ordinary circumstances the removal of such a bandage after such an operation is extremely painful but with my new bandage and itsoperation .on the;

principle of decreasing diameter as it is with drawn, there is less discomfort.

The foregoing is intended as illustrative and not as limitativesince other and further modifications may be made without departing from; the invention as defined-by'the appended claims;

I claim:

1.;A post-operative bandage adapted for in-- sertion into a body cavity and to be-withdrawn. therefrom while decreasing the diameter of the bandage comprising inner'and outer soft, pliant portions of tubular cellulosic material'of which the'inner-portion'is normally inturned and disposed'within' the outer portionand is unitarily connected thereto at one end.

2.1Abandage as defined by claim 1, which-is composedof an initially tubular-shape one end. ofhwhich-has been-bent in upon itself and "drawn through the opening thereof-until it'forms an inner portion within an outerportion the inner portion-projecting slightly beyond the outer portion ,to; provide a terminal portion for reducing.

3. A bandage in accordance with claim 2, in which the outer portion has a bore which is normally only slightly larger than the inner portion and the inner portion has a small bore which acts as a passageway through the entire bandage.

4. A bandage in accordance with claim 3, in which the passageway through the bandage is small in diameter compared to the diameter of the bandage and the thickness of the inner'bandage portion.

5. A post-operative bandage adapted to be inserted in the anal canal after hemorrhoidectomy and to'be withdrawn therefrom while decreasing the diameter of the bandage which comprises inner-and outer tubular portions of soft, pliant, cellulosic material,..the inner tubular portion being disposed in the bore of the outer tubular portion and having one end thereof projecting therebeyond and being connected at its other end to said outer tubular portion, the bandage as a whole being characterized by having an axialpassage way therethrough. 4
