Male External Catheter with Absorbent and Adhesive

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.

We claim: 
     
         1 . An external urinary catheter, comprising:
 a tubular sheath including a closed distal end and an open proximal end;   a layer of adhesive material non-releasably bonded to a portion of an inner surface of the tubular sheath; and   an absorbent material positioned distal to the layer of adhesive material, the absorbent material being provided in a packet configured to be replaced and exchanged without utilizing another tubular sheath.   
     
     
         2 . The external urinary catheter according to  claim 1 , wherein the packet comprises a semi-permeable coverstock containing and surrounding the absorbent material. 
     
     
         3 . The external urinary catheter according to  claim 1 , wherein the inner surface is rolled onto an outer surface of the tubular sheath in a storage configuration, the adhesive material releasably contacting the outer surface. 
     
     
         4 . The external urinary catheter according to  claim 1 , wherein the absorbent material is isolated from an adjacent section of the tubular sheath by a semi-permeable barrier. 
     
     
         5 . The external urinary catheter according to  claim 4 , wherein the semi-permeable barrier comprises a spunbound synthetic fiber coverstock. 
     
     
         6 . The external urinary catheter according to  claim 1 , wherein the absorbent material is positioned in the closed distal end of the tubular sheath. 
     
     
         7 . The external urinary catheter according to  claim 1 , wherein the tubular sheath is formed of silicone rubber. 
     
     
         8 . The external urinary catheter according to  claim 1 , wherein the distal end of the tubular sheath has an end dimension that is different than a diameter of the proximal end. 
     
     
         9 . The external urinary catheter according to  claim 1 , wherein the distal end of the tubular sheath has an end dimension that is greater than a diameter of the proximal end. 
     
     
         10 . The external urinary catheter according to  claim 1 , wherein the absorbent material is isolated from an adjacent section of the tubular sheath by a semi-permeable barrier. 
     
     
         11 . The external urinary catheter according to  claim 10 , wherein the semi-permeable barrier comprises a spunbound synthetic fiber coverstock. 
     
     
         12 . The external urinary catheter according to  claim 1 , wherein the absorbent material is positioned in the closed distal end of the tubular sheath. 
     
     
         13 . The external urinary catheter according to  claim 1 , wherein the absorbent material includes cellulose fiber.
