External catheter and applicator

Claim 2

An external catheter and applicator combination, said catheter comprising an elastic sheath having upper and lower portions and inner and outer surfaces, wherein one end is adapted for transporting urine to a suitable reservoir and the other end is adapted to receive the glans of the penis; an applicator comprising a relatively rigid longitudinally extending ring means having inner and outer surfaces and an inside diameter which is slightly greater than the outside diameter of the lower portion of said sheath; said upper sheath portion extends longitudinally and is everted longitudinally over at least a portion of the outer surface of the lower portion of the outer sheath portion forming an everted outer surface, wherein at least a portion of the inner surface of the ring means contacts a portion of said everted outer everted surface of the upper sheath portion, the lower sheath portion being suitably sized to allow insertion of the penis and wherein when the ring means is slideably moved along the penile shaft said everted inner surface of the upper sheath portion is caused to revert along the penile shaft.

Claim 3

The catheter and applicator combination according to claim 1, wherein a portion of the everted sheath extends below the ring and is reverted over the outer surface of said ring.

Claim 4

The catheter and applicator combination according to claim 1, wherein the inner sheath surface everted over the lower sheath portion contains an adhesive coating said adhesive being transferred to the penile shaft when said ring is slidably moved along said shaft.

Claim 5

The catheter and applicator combination according to claim 1, wherein the upper and lower portions of said sheath are integral and wherein the upper portion is constructed from a thin, stretchable elastic material and the lower portion of said sheath is constructed from a thicker gauge of elastic material such that said lower portion is substantially shape-retaining.

Claim 6

The catheter and applicator combination according to claim 1, wherein the distal end of the lower portion of the sheath is gradually tapered to form an outlet and tube for transporting urine to said reservoir.

Claim 7

The catheter and applicator combination according to claim 1, wherein the inner circumferential surface of the lower sheath portion contains a pressure-sensitive adhesive coating.

Claim 8

An external catheter and applicator combination, said catheter comprising an elastic sheath having upper and lower portions and inner and outer surfaces, wherein one end is adapted for transporting urine to a suitable reservoir and the other end is adapted to receive the glans of the penis; an applicator comprising a relatively rigid split, hinged ring having inner and outer surfaces and an inside diameter which is slightly greater than the outside diameter of the lower portion of said sheath; said upper sheath portion being everted over the outer surface of the lower sheath portion and said everted upper sheath portion being surrounded by said ring so that the inner ring surface contacts a portion of the everted inner sheath surface; whereby when the glans of the penis is inserted into the end of the sheath adapted to receive the same and said ring is slidably moved along the shaft of the penis, the everted portion of the said sheath reverts along said shaft.

Claim 9

An external catheter and applicator combination, said catheter comprising an elastic sheath having upper and lower portions and inner and outer surfaces, wherein one end is adapted for transporting urine to a suitable reservoir and the other end is adapted to receive the glans of the penis; an applicator comprising a relatively rigid split, hinged ring having inner and outer surfaces and an inside diameter which is slightly greater than the outside diameter of the lower portion of said sheath; said upper sheath portion being everted over the outer surface of the lower sheath portion and said everted upper sheath portion being surrounded by said ring so that the inner ring surface contacts a portion of the everted inner sheath surface; whereby when the glans of the penis is inserted into the end of the sheath adapted to receive the same and said ring is slidably moved along the shaft of the penis, the everted portion of the said sheath reverts along said shaft.

Claim 10

The catheter and applicator combination according to claim 7, wherein the length of said split and hinged ring is sufficient to at least cover the adhesive strip; and wherein one end of said ring has a flange and the outside surface of said ring has a circumferential groove.

Claim 11

An external catheter and applicator combination, said catheter comprising an elastic sheath having upper and lower portions and inner and outer surfaces, wherein the distal end of the lower portion is adapted for transporting urine to a suitable reservoir and the proximal end of said lower portion is adapted to receive the glans of the penis; an applicator comprising a relatively rigid longitudinally extending ring means having inner and outer surfaces and an inside diameter which is slightly greater than the outside diameter which is slightly greater than the outside diameter of the lower portion of said sheath; said upper sheath portion extends longitudinally and is everted longitudinally over at least a portion of the outer surface of the lower sheath portion forming an outer everted surface, wherein at least a portion of the inner surface of the ring means contacts a portion of said everted outer everted surface of the upper sheath portion, the lower sheath portion being suitably sized to allow insertion of the penis and wherein when the ring means is slideably moved along the penile shaft said everted inner surface of the upper sheath portion is caused to revert along the penile shaft.

Claim 12

An external catheter and applicator combination, said catheter comprising an elastic sheath having upper and lower portions and inner and outer surfaces, wherein the distal end of the lower portion is adapted for transporting urine to a suitable reservoir and the proximal end of said lower portion is adapted to receive the glans of the penis; an applicator comprising a relatively rigid longitudinally extending ring means having inner and outer surfaces and an inside diameter which is slightly greater than the outside diameter which is slightly greater than the outside diameter of the lower portion of said sheath; said upper sheath portion extends longitudinally and is everted longitudinally over at least a portion of the outer surface of the lower sheath portion forming an outer everted surface, wherein at least a portion of the inner surface of the ring means contacts a portion of said everted outer everted surface of the upper sheath portion, the lower sheath portion being suitably sized to allow insertion of the penis and wherein when the ring means is slideably moved along the penile shaft said everted inner surface of the upper sheath portion is caused to revert along the penile shaft.

Claim 13

The catheter and applicator combination according to claim 9, wherein a portion of the everted sheath extends past the ring toward the lower end of the sheath and is reverted over the outer surface of said ring in a direction away from the lower end of the sheath.

Claim 14

The catheter and applicator combination according to claim 9, wherein a portion of the inner surface of the upper sheath portion everted over the lower sheath portion is coated with an adhesive, at least a portion of said adhesive being in releasable contact with the inner surface of said ring such that said adhesive is transferred to the penile shaft when said ring is slidably moved along said shaft.

Claim 15

The catheter and applicator combination according to claim 9, wherein the inner sheath portion is coated with an adhesive, said adhesive being in releasable contact with the inner surface of the ring; and wherein the inner surface of the ring extends along the everted inner surface of the upper sheath portion sufficiently to at least cover said adhesive.
