First Claim
Patent Images
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; and
an 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.

Abstract
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.

12. An external urinary catheter, comprising:
-
a tubular sheath of silicone rubber, the tubular sheath having an inner surface and an 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; and an 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. - View Dependent Claims (13, 14, 15, 16, 17)
