URINE ABSORBENT PAD

Abstract

A disposable urine trap in the form of a foldable pad that envelops the male genitalia and closes around the organ to form a barrier that prevents urine from escaping the trap. The pad includes an asymmetric pair of wings that are separated by a gap and attached to the main body of the pad. The first wing is preferably rectangular in that the distal angles are substantially right angles with parallel side edges and a perpendicular distal edge, and has a length that exceeds a length of a second wing, which is terminates so that the distal edge of the second wing is angled to form an obtuse and an acute angle with respect to its generally parallel sides.

DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0028] FIG. 1 illustrates a plan view of a first preferred embodiment of the present invention, comprising a pad 12 generally formed by a base 24 and first and second wings 14, 16. The pad 12 is formed by enclosing fluid absorbent material between an fluid impervious outer lining 18 and a soft fluid transmissive inner lining 20. The outer lining 18 may be made of a polyethylene film or other low cost, biocompatible material to seal in the urine and prevent leakage outside of the trap. The inner lining 20 that bear's against the user's skin may be made of polypropylene or suitable non-abrasive, non-toxic material that transmits fluid while largely staying relatively fluid free at the surface. The absorbent center 22 may contain wood pulp and super-absorbent polymers such as sodium polyacrylate. Sodium polyacrylate is effective in wicking away fluid from the skin through the inner lining 20, and can soak up to 30 times its weight in urine. The absorbent center is bordered around its edges by adhering the inner lining 20 and outer lining 18, and the matching of the two mating linings 18,20 can be arranged to give the pad a rounded shape in the undeformed condition. That is, a shallow bowl or saucer is created by the fit of the two mating edges such that the edges of the pad are raised with respect to the base 24. The base 24 is particularly padded at this middle portion, which is where the introduction of urine is expected in most cases.

[0029] As further seen in FIG. 1, a first elongated wing 14 extends distally from a crease 30. The first wing 14 is elongated and includes an outer side edge 32, an inner side edge 34, and a distal edge 36. The side edges 32,34 are substantially parallel, and the distal edge substantially perpendicular thereto, such that right angels , are formed. A generally triangular portion 36 of the inner edge 34 is removed at the juncture 38 of the first and second wings 14, 16, creating half of a void 42 through which the penis 76 is inserted.

[0030] An elongated second wing 16, which in a preferred embodiment has a length that is approximately one half a length of the first wing 14, protrudes distally to a crease 52 and includes an inner side edge 46, outer side edge 48, and distal edge 50. As with the first wing, the inner side edge 46 and outer side edge 48 are substantially parallel, but the distal edge 50 forms an acute angle with the outer side edge 48 and an obtuse angle with the inner side edge 46. A triangular portion 54 of the inner edge 46 is removed at the juncture 38 of the first and second wings 14, 16, creating the other half of the void 42, which is thusly formed in a shape of a diamond based on the two triangular resections 36,54 on the inner edges 34, 46 to define an opening.

[0031] FIG. 2 illustrates a rear view of the pad 12, including a peel away adhesive strip 70 that can be used to secure the pad to the patient or a waistband of the patient. A second adhesive strip 72 is used to hold the pad in a pouch, or folded position to envelope the patient's genitalia 76.

[0032] FIGS. 3-13 illustrate a first method for how the pad 12 encloses the male organ and creates a cocoon-like conically shaped wrap around the organ to collect any urine and prevent leakage. With the patient 80 preferably standing or lying on his back, the pad 12 is placed on the user's thighs with the first wing 14 on the upper right thigh/abdomen and the second wing 16 over the user's left thigh/abdomen. The user's penis 76 is placed in the void 42 between the first and second wings 14,16 so that the base of the penis is at the juncture 38 and the head of the penis is in the central portion, or base 24 of the pad 12 (FIG. 4). The first wing 14 is then folded along crease 30 over the top of the penis such that the inner side edge 34 is approximately along crease 52 (FIGS. 4, 5). The placement of the first wing 14 in this position covers the penis 76, and exposes the adhesive strip 72 adjacent the second wing 16. The protective cover is removed from the adhesive strip 72 (FIG. 6), and the second wing 16 is then folded at crease 52 over the first wing 14 such that the distal edge 50 is approximately parallel to and adjacent to the side outer edge 32 of the first wing 14 (FIG. 7). This configuration encloses the penis 76 in the opening 42 and creates a leak-proof pouch over the penis. The first and second wings 14, 16 overlap and cooperate to form a V over the penis (FIG. 8), and the corners 64 can then be folded over the V in the direction of arrow 300 (FIG. 8) to close the pouch like an envelope, eliminating any opportunity for urine to escape during urination. A double layer of protection created by the wings 14, 16 (FIGS. 12 and 13) reduce the opportunity for leakage and create a drier, more moisture-free environment for the user 80.

[0033] As shown in FIGS. 9-11, the urine trap 12 can be placed inside a diaper or underpants 90 of a patient 80 without the need to fully undress the patient. If the patient should have incontinence while wearing the urine trap, it can be removed easily and replaced by a new pad with minimal jostling or movement of the patient. The larger adhesive strip 70 can be placed on the backside of the pad to secure the pad to the patient's waistband 92 of his pants or underwear 90 to maintain the urine trap in position. Alternatively, a plurality of adhesive strips can be secured to the back side or front side of the urine trap to secure it to a gown or other more loose-fitting clothing.

[0034] The unique shape of the first and second wings have multiple benefits over the existing prior art. First, the wings minimize the amount of material needed to establish a secure and reliable pouch, and eliminate excess flaps that can catch on garments and inadvertently open the pouch. For example, the inner side edge 46 of the second wing 16 aligns with the base of the first wing 14 at the crease 30 when the second wing 16 is folded over the first wing 14. Similarly, the inner side edge 34 of the first wing 14 aligns perfectly with the base of the second wing 16 at the crease 52 when the first wing 14 is folded over the penis. The alignment of the inner edges against the opposite crease maximizes the volume of the pouch and eliminates excess wing material bunching up or contacting the penis. The novel shape aligns the edges of the wings to ends of the pouch itself, creating a perfectly formed and reliable pouch with no excess material. Second, cut-outs 36, 54 form a more comfortable opening through which the wearer's penis is secured, reducing chaffing and skin irritation. By eliminating all excess material, the user can wear the urine trap under regular clothes as well without large, bulky bulges that can be created by traditional diapers. A taped border may extend along the wings from the respective creases to ensure that the edges mate more smoothly and prevent gaps that can cause leakage.

[0035] In an alternative embodiment as shown in FIGS. 14-23, the pouch can be applied and worn in a reverse manner. Advantages may be seen in this configuration depending on whether the user is prone or ambulatory. The adhesive strip may be secured to the user 80 in this embodiment, wear only a gown or other loose fitting clothing are worn and there is nothing else to which one can apply the adhesive strip.

[0036] The foregoing description is intended to be illustrative and not exclusive. That is, there are many variations and modifications that can be made to the foregoing descriptions and preferred embodiments that would be readily apparent to one of ordinary skill in the art, and the present invention is intended to include all such modifications and variations. Such modifications may include choice of materials, overall dimensions of the embodiment, etc. Accordingly, the scope of the present invention should not be limited to any specific embodiment, illustration, or description herein, but rather the scope of the invention should be determined by the appended claims using the plain and ordinary meaning of the words used therein.
