The invention relates generally to external urinary catheters for males. More specifically, the invention relates to an external urinary catheter that includes an absorbent material to absorb urinary discharge. The absorbent material can be located in either a distal end of a tubular sheath, or in a receptacle that attached to the distal end of the tubular sheath. The tubular sheath of the external urinary catheter can include a tubular sheath of silicone rubber, wherein the sheath has an inner surface and an outer surface, and a layer of adhesive material directly and non-releasably bonded to the inner surface.
1. An external urinary catheter, comprising: a tubular sheath of silicone rubber, the tubular sheath having an inner surface and an outer surface;a layer of adhesive material for securing the tubular sheath to a user at a location during use, the layer of adhesive material being non-releasably bonde
1. An external urinary catheter, comprising: a tubular sheath of silicone rubber, the tubular sheath having an inner surface and an outer surface;a layer of adhesive material for securing the tubular sheath to a user at a location during use, the layer of adhesive material being non-releasably bonded to a portion of the inner surface of the tubular sheath;a receptacle detachably interconnected to a distal end of the tubular sheath, the receptacle defining an interior in which urinary discharge is collected; andan absorbent material disposed within the interior of the receptacle to absorb the urinary discharge, the absorbent material being contained within and surrounded by a semipermeable coverstock;wherein prior to use, the inner surface of the silicone rubber sheath is rolled up upon the outer surface of the silicone rubber sheath for storage, and wherein the adhesive material bonded to the inner surface releasably contacts portions of the outer surface of the tubular sheath, and wherein the receptacle is sized such that the receptacle resides within a user's pelvic region when the catheter is worn. 2. The catheter of claim 1, wherein the absorbent material includes cellulose fiber. 3. The catheter of claim 1, further including a joining assembly positioned between the distal end of the tubular sheath and the receptacle, the joining assembly providing fluid communication between the tubular sheath and the receptacle. 4. The catheter of claim 3, wherein the joining assembly is detachably interconnected to the distal end of the tubular sheath. 5. The catheter of claim 3, wherein the joining assembly includes a fitting sized for receipt within an opening formed in the distal end of the tubular sheath, the fitting and receptacle being detachable from the opening of the tubular sheath. 6. The catheter of claim 1, wherein the interior volume of the receptacle is sized to collect no more than 100 mL of urine. 7. The catheter of claim 1, wherein the interior volume of the receptacle is between about 1.0 and 5.0 cubic inches. 8. The catheter of claim 1, wherein the receptacle has a width and a height, the width being between about 2.0 and 3.0 inches, and the height being between about 3.0 and 4.0 inches. 9. The catheter of claim 1, wherein the catheter secures to the user only at the location contacted by the layer of adhesive material. 10. The catheter of claim 1, wherein the semi-permeable coverstock permits the urinary discharge to pass through the semi-permeable coverstock to the absorbent material, and prevents the urinary discharge from migrating back through the semi-permeable coverstock to a main portion of the tubular sheath. 11. The catheter of claim 1, wherein a packet comprises the semi-permeable coverstock and the absorbent material. 12. An external urinary catheter, comprising: a tubular sheath of silicone rubber, the tubular sheath having an inner surface andan outer surface, the tubular sheath further having a main portion and a bulbous distal end, the main portion being sized to receive an user's penis, the bulbous distal end being greater in diameter than the main portion of the tubular sheath;a layer of adhesive material that secures the tubular sheath to the user's penis at a location during use, the layer of adhesive material being non-releasably bonded to a portion of the inner surface of the tubular sheath; andan absorbent material disposed in the bulbous distal end of the tubular sheath to absorb urinary discharge, the absorbent material being contained within and surrounded by a semipermeable coverstock;wherein prior to use, the inner surface of the silicone rubber sheath is rolled up upon the outer surface of the silicone rubber sheath for storage, and wherein the adhesive material bonded to the inner surface releasably contacts portions of the outer surface of the tubular sheath, and wherein the entire external urinary catheter resides within a user's pelvic region when the catheter is worn. 13. catheter of claim 12 wherein the absorbent material includes cellulose fiber. 14. The catheter of claim 12 wherein the tubular sheath includes a necked portion located between the main portion and the bulbous distal end. 15. The catheter of claim 12 wherein the catheter secures to the user only at the location contacted by the layer of adhesive material. 16. The catheter of claim 12, wherein the semi-permeable coverstock permits the urinary discharge to pass through the semi-permeable coverstock to the absorbent material, and prevents the urinary discharge from migrating back through the semi-permeable coverstock to a main portion of the tubular sheath. 17. The catheter of claim 12, wherein a packet comprises the semi-permeable coverstock and the absorbent material. 18. An external urinary catheter, comprising: a tubular sheath of silicone rubber, the tubular sheath having an inner surface and an outer surface;a layer of adhesive material for securing the tubular sheath to a user at a location during use, the layer of adhesive material being non-releasably bonded to a portion of the inner surface of the tubular sheath;an absorbent material disposed in relation to the tubular sheath to absorb urinary discharge, the absorbent material being contained within and surrounded by a semipermeable coverstock; andwherein prior to use, the inner surface of the silicone rubber sheath is rolled up upon the outer surface of the silicone rubber sheath for storage, and wherein the adhesive material bonded to the inner surface releasably contacts portions of the outer surface of the tubular sheath. 19. The catheter of claim 18 wherein the semi-permeable coverstock permits the urinary discharge to pass through the semi-permeable coverstock to the absorbent material, and prevents the urinary discharge from migrating back through the semi-permeable coverstock to a main portion of the tubular sheath. 20. The catheter of claim 18 wherein the tubular sheath has a main portion and a distal end, the absorbent material being disposed in the distal end of the tubular sheath. 21. The catheter of claim 18 further including a receptacle attached to the distal end of the tubular sheath, the absorbent material being disposed within the receptacle. 22. The catheter of claim 18, wherein a packet comprises the semi-permeable coverstock and the absorbent material. 23. An external urinary catheter, comprising: a tubular sheath of silicone rubber, the tubular sheath having an inner surface and an outer surface;a layer of adhesive material for securing the tubular sheath to a user at a location during use;a receptacle detachably interconnected to a distal end of the tubular sheath by a joining assembly, the receptacle defining an interior in which urinary discharge is collected, the receptacle residing within a user's pelvic region when the catheter is worn, the joining assembly including a fitting received within an opening formed in a distal end of the tubular sheath; andan absorbent material disposed within the interior of the receptacle to absorb the urinary discharge, the absorbent material being contained within and surrounded by a semipermeable coverstock. 24. The catheter of claim 23, wherein the fitting has a tapered end that is received within the opening of the tubular sheath. 25. The catheter of claim 23, wherein prior to use, the inner surface of the silicone rubber sheath is rolled up upon the outer surface of the silicone rubber sheath for storage, and wherein the adhesive material bonded to the inner surface releasably contacts portions of the outer surface of the tubular sheath. 26. The catheter of claim 23, wherein the semi-permeable coverstock permits the urinary discharge to pass through the semi-permeable coverstock to the absorbent material, and prevents the urinary discharge from migrating back through the semi-permeable coverstock to a main portion of the tubular sheath. 27. The catheter of claim 23, wherein a packet comprises the semi-permeable coverstock and the absorbent material.
