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.

Claims

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 wherein the absorbent material is contained within and surrounded by a semi-permeable coverstock.

2. The external urinary catheter according to claim 1, wherein the tubular sheath is formed of silicone rubber.

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 distal end of the tubular sheath has an end dimension that is different than a diameter of the proximal end.

5. 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.

6. 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.

7. The external urinary catheter according to claim 6, wherein the semi-permeable barrier comprises a spunbound synthetic fiber coverstock.

8. The external urinary catheter according to claim 1, wherein the coverstock is a spunbound synthetic fiber selected from the group consisting of polyester and polypropylene.

9. The external urinary catheter according to claim 1, wherein the absorbent material is positioned in the closed distal end of the tubular sheath.

10. The external urinary catheter according to claim 1, wherein the absorbent material includes cellulose fiber.

11. 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;

an absorbent material positioned distal to the layer of adhesive material; and

a receptacle detachably interconnected to the distal end of the tubular sheath, the receptacle defining an interior in which urinary discharge is collected, the absorbent material positioned in the receptacle, wherein the absorbent material is contained within and surrounded by a semi-permeable coverstock.

12. The external urinary catheter according to claim 11, wherein the receptacle is configured to reside within a user'"'"'s pelvic region when the catheter is worn.

13. The external urinary catheter according to claim 11, further comprising 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.

14. The external urinary catheter according to claim 11, wherein the interior has a volume sized to collect no more than 50 mL of urine.
