Definitions

• ABSTRACT A sheath arrangement for a male urinal device in which there is a urinal sheath of flexible material designed to extend over a substantial portion lengthwise of the penis and a liner pad of synthetic, resiliently compressible, deformable, waterproof material in the form of a relatively wide strip to be wound around the penis to form a cushion between the penis and the sheath.
• the liner pad is wide enough to extend from the head of the penis upwardly along the penal shaft a sufficient distance to provide an adequate cushion between the sheath and the penis and long enough to be wrapped at least one and a half turns around the penis.
• the liner pad may be either of a polymer-oil elastomeric combination or of a closed cell foam material and, preferably, has at least one adhesive surface as to cling to the penis.
• Urinal devices of this type must be worn for very long periods of time, particularly in the case of a paraplegic. Because of the tape being relatively tight, it exerts continuous pressure on the penis and particularly on the urethral passage which is located on the. underside of the penis fairly close to the surface. This can cause partial constriction of the urethral passage and considerable discomfort. If the tape is sufficiently loose so as to avoid this irritation, there is always danger that leakage of urine may occur be tween the sheath and the penis.
• the present invention is concerned with a sheath arrangement for such a male urinal device in which the discomfort experienced by the wearer when a urinal sheath of elastic material is worn for a long time is avoided by the use ofa liner pad of synthetic, resiliently compressible, deformable, waterproof material in the form of a relatively wide strip which is wound around the penis for at least one and a half turns to form a long cushion between the penis and the sheath.
• the liner pad is preferably of a width such that it extends from a point close to the head of the penis to an area near the upper end of the sheath so that practically the entire portion ofthe penis upon which any pressure would be exerted by the sheath or tape is protected by the liner pad.
• the liner pad is preferably deformed after being applied so that the overlapping portions closely fit together to produce a liquid-tight barrier.
• the liner pad preferably has an adhesive surface to retain the pad in position on the penis as well as to maintain the sheath in place with respect to the liner.
• liner pad which we employ is a pad of a polymer-oil elastomeric combination. Such a material forms a very soft pad which readily conforms to the shape of the penis and causes no irritation, even when worn for long periods of time. The material, furthermore, tends to adhere to itself so that it forms a good seal between the penis and the sheath.
• An alternative form of liner pad which we may employ is one formed of a closed cell polyurethane foam.
• One form of polyurethane foam particularly suitable for this purpose is one which is cross linked by electron radiation.
• the elastic tape is preferably of a type which is capable of adhering to an underlying layer of the tape when wrapped under tension.
• the tape may be initially corrugated before being tensioned so as to increase its extensibility.
• the elastic tape while wide, is somewhat narrower than the liner pad so that it terminates before the end of the sheath. It thus acts to press the sheath down against the liner pad over the intermediate portion of the liner pad.
• FIG. I is a plan view of a penis with my improved sheath arrangement secured thereto, the bottom portion of the sheath being broken away;
• FIG. 2 is a view similar to FIG. 1 but with the sheath arrangement shown in longitudinal cross-section;
• FIG. 3 is a sectional view through the sheath arrangement and the penis taken along the line 33 of HG.
• FIG. 4 is a cross-sectional view of a portion of a strip of the elastic tape, showing the tape in the corrugated condition it assumes when not under tension;
• FIG. 5 is a plan view similar to FIG. 1 but showing a modified form of the liner pad.
• FIG. 6 is a cross-sectional'view of a modified form of our sheath construction
• FIG. 7 is a cross-sectional view through the sheath arrangement of FIG. 6 and the penis to which the sheath arrangement is applied, the section being taken along the line 77 of FIG. 6;
• FIG. 8 is a view of the liner pad used in the modification of FIGS. 6 and 7 with portions of the protecting backing partially peeled away;.and
• FIG. 9 is a fragmentary cross sectional view of a portion of the sheath with the body portion completely rolled up until it engages the bulbous portion of the sheath.
• the sheath of our invention is indicated by the reference numeral 11.
• This comprises a very thin body portion 12, joined at 19 to a conical portion 13 terminating in a tubular portion 14 extending to some urine receptacle (not shown).
• the sheath is formed of a flexible material, which may be elastic, and the conical portion 13 and tubular portion 14 are formed of relatively heavy material so as not to Urinal Device, Ser. No. 331,684 filed Feb. 12, 1973.
• the sheath has, in certain prior devices, been held rather snugly against the penis by a narrow tape wrapped under tension about the sheath to form a relatively liquid tight seal with the surface of the penis. Unfortunately, this results in constriction of the urethral passage and discomfort to the wearer when the sheath must be worn for long periods of time.
• a liner pad 16 is disposed between the penis and the body portion 12 of the sheath 11.
• This liner pad is formed by wrapping around the penis prior to the application of the sheath 11 thereto, a strip of synthetic, resiliently compressible waterproof material.
• the strip should be of a length sufficient to wrap around the penis and overlap somewhat, preferably at least one and a half turns altogether. In other words, the length of the strip should be substantially greater than the circumference of the penile shaft.
• FIG. 3 is a cross-sectional view, that the strip 16 in the particular example shown in the drawing, cornpletes almost two full turns around the penis.
• the strip should be of a width sufficiently great to extend from a point adjacent to the head 17 of the penis to a point near the rolled portion of the sheath 1 1. In this modification, the strip is wide enough to extend above the end of the rolled portion. We found that a strip of a width between 2 /2 and 2% inches is desirable.
• the liner pad 16 is formed of a polymer-oil elastomeric combination. A suitable material of this type is described in the Lindhof US. Pat. No. 3,676,387, granted July 11, 1972. Such a material is resilient but somewhat deformable. Thus, as shown in FIG.
• the sheath 11 can now be positioned on the penis. As pointed out above, this is done by initially having the sheath completely rolled up. The sheath is then placed over the end of the penis and the body portion 12 is then unrolled until a short distance remains between the end of the sheath and the end of the liner pad 16. Since there is some tendency for the sheath material, particularly where it is a resilient material such as latex, to adhere to the polymer-oil elastomeric material of which the pad 16 is formed, it is desirable before the sheath is unrolled to the position shown in FIGS. 1 and 2, to apply some powder such as talcum powder to the pad 16.
• This talcum powder may be applied only over the upper portion of the pad 16 so that the lower portion of the sheath still adheres to the pad 16. This aids in maintaining the sheath in position with respect to the pad. By placing powder over at least the upper portion of the pad 16, it is possible to more readily remove the sheath 11.
• an elastic tape 18 which is wound over the sheath in a plurality of layers.
• a tape which tends to adhere to an underlying layer when wrapped under tension over an object. This may be accomplished either by use of a pressure sensitive adhesive coating or by use of a material which by reason of its composition and surface texture tends to result in adhesion of overlapping layers under tension.
• a type of tape which is particularly suitable for this purpose is that marketed under the trademark Coban.
• Such a tape is formed of spaced aligned elastic yarns which are sealed between two thin porous gathered nonfibrous webs by means of a soft flexible coherent binder.
• the tape 18 is relatively wide. In actual practice, we employ a tape which is two inches wide. While this is substantially shorter than the liner pad 16, it is nevertheless wide enough so that the pressure it exerts is distributed over a relatively long portion lengthwise of the penis.
• the urethral passage is indicated by the numeral 20. It will be noted that this passage is relatively close to the surface of the penis on the underside. It would be obvious that if the sheath 11 were directly applied over the penis and if a relatively narrow non-elastic band were applied over the sheath to hold the sheath in position, considerable restriction of the urethral passage could result. With our arrangement, however, this is overcome in several ways. In the first place, because of the nature of the liner pad 16, any pressure exerted upon the sheath by the tape 18 is absorbed to a large extent by the cushioning effect provided by pad 16.
• the construction of the present invention enables the sheath to be worn with a high degree of comfort. This is extremely important whenever a urinal of this type must be worn more or less continuously for long periods of time.
• FIG. 5 The modification of FIG. 5 is basically the same as sixteenth of an inch thick and 6 inches long. This results in a number of layers of the material about the penis. Thus, while the thickness of the foam material is only about half that which is employed when the polymer-oil elastomeric combination is employed, the
• the elastic tape 18 is applied in the same way and functions in the same manner. In each case, it acts to hold the sheath ll firmly in engagement with the liner material to prevent any leakage around the liner material between the sheath and the penis.
• the effect of the wide cushioned pad 25 along with the wide elastic tape 18 is to result in a sheath construction in which there is a minimum amount of discomfort in wearing the urinal sheath.
• the waterproof nature of the liner pad and the tendency of the material to conform to adjacent surfaces there is very little opportunity for any leakage between the sheath and the penis.
• an elastic tape was employed outside of the sheath.
• the purpose of this elastic tape was to insure that there was no leakage between the sheath and the penis and to hold the sheath in position on the penis.
• FIGS. 6 through 8 The modified form of our construction is shown in FIGS. 6 through 8.
• the sheath 11 is basically the same as in FIGS. 1 through 5 and the same reference characters have been applied to designate it,
• a liner which has at least one adhesive surface and which is readily deformable so as to form when wrapped around the penis a soft cushion which forms a complete seal against fluid between the sheath and the penis.
• the material is sufficiently soft and yieldable to cause very little irritation.
• the liner pad 35 is formed of a blend of nitrile rubber and polyvinyl chloride which has been expanded to form a closed cell foam structure.
• a typical material of this type is disclosed in the Daly et al. U.S. Pat. No. 2,570,182 granted Oct.,9, Such material is sold under the trade name Ensolite Type M by Uni-Royal, Inc. Secured to the opposite surfaces of this material are adhesive layers 26 and 27 of an adhesive which is adhesive pressure sensitive and nonirritating.
• a typical adhesive of this type is sold under the trade name Mactoc by Morgan Adhesive Company of Stowell, Ohio. This adhesive is a copolymer of 2-ethyl-hexyl-acrylate and vinyl acetate.
• the adhesive has the properties of having substantial tensile strength and adhering to the skin but readily separable therefrom. Secured to the adhesive layers 26 and 27 are liner strips 28 and 29 so as to prevent the adhesive layers 26 and 27 adhering to other objects until the liner pad is to be used.
• a typical liner pad as shown in FIG. 8, is 1% inches wide, 5% inches long and three thirty-seconds inch in thickness.
• the width will, of course, depend upon the length of the penis and the length upon the circumference.
• the length should be positioned that the strip can be wrapped around at least l /z times. Thus, the length should be at least 1 /2 times the circumference of a typical penis when in flaccid condition. Referring to FIGS. 6 and 7, it will be noted that the strip 35 is wrapped around the penis 10 about 2 /2 times.
• the liner strips 28 and 29 are removed and the liner pad 35 is wrapped around the penis relatively firmly.
• the liner pad may now be molded to the penis by grasping the wound liner and forcing it firmly against the penis.
• the sheath is then rolled back on itself as far as it will go, that is until the rolled portion 15 approaches the re-entrant portion 12.
• the position of the sheath when rolled back in this manner is shown'in FIG. 9. It will be noted that the rolled portion 15 of the sheath is in engagement with the bulbous portion of the sheath so that the inner diameter of the roll 15 tends to expand slightly to conform with the inwardly increasing diameter of the curved portion of the sheath adjacent to point 19.
• the roll 15 at this point has only a few remaining turns to it, it exerts practically no constricting force upon the penis 10. Furthermore, because of the fact that it extends over the end of the liner pad which is of much greater outer circumferential extent than the penis 10 at the point where it is surrounded by the roll 15, the roll is prevented from exerting any particular pressure upon the penis 10. The engagement of the roll 15 with the penis is not relied upon to effect a seal. Rather, the seal is effected between the sheath and the liner pad 35 and in turn between the liner pad 35 and the penis.
• the box also contains a roll of the elastic tape.
• the buyer is able to obtain in a simple container all of the components of our novel sheath construction.
• a sheath arrangement for a male urinal device comprising:
• a urinal sheath of flexible material designed for application to a penis for covering a substantial portion lengthwise of the same and having a reduced portion for extending over and beyond the tip of the penis; said reduced portion having connection means secured thereto for connecting the sheath through a suitable conduit to a urine receptacle, and
• a liner pad of synthetic, resiliently compressible deformable waterproof material in the form ofa strip of such material having a width of well over half of the length of the upper portion of the sheath above the reduced portion so as to extend over a substantial portion lengthwise of a normal flaccid penis and of a length substantially greater than the circumference of such a normal flaccid penis to enable the strip to be wrapped at least one and a half turns around the penis before application thereto of said sheath, the thickness of said strip being less than one-fourth of an inch to facilitate wrapping said strip about the penis.
