Inflatable catheter for a male urinal

Claim 2

A male incontinence device having a receiving end adapted to be applied to a user's organ and a drain end adapted to convey the user's urine to an external urine collection means, said incontinence device comprising: an outer tubular sheathing formed from a flexible material, an inner tubular sheathing formed from a flexible material, said inner and outer tubular sheathings joined together at each of the device receiving and drain ends, such that an annular, inflatable fluid chamber is formed between said inner and outer sheathings and an axially extending urine drain passage is formed at the interior of said inner sheathing, said fluid chamber and said drain passage having substantially identical linear dimensions through said device, urine conveying means having a relatively narrow diameter with respect to said urine drain passage to interconnect said inner tubular sheathing to said urine collection means, whereby to cause said inner sheathing to constrict at the drain end of said device, and fluid source means adapted to be connected to said fluid chamber for inflating said chamber, whereby said inner sheathing is collapsed under pressure around the user's organ and said drain passage is evacuated, so that urine is extracted therefrom by means of suction when said device is connected to the urine collection means and urine backflow from the collection means to said drain passage is prohibited.

Claim 3

The incontinence device recited in claim 1, wherein said inner and outer tubular sheathings are aligned in a substantially concentric relationship with respect to one another between said device receiving and drain ends.

Claim 4

The incontinence device recited in claim 1, wherein said outer sheathing is substantially thicker than said inner sheathing.

Claim 5

The incontinence device recited in claim 3, wherein said outer sheathing is approximately at least 10 times thicker than said inner sheathing.

Claim 6

The incontinence device recited in claim 1, wherein each of said fluid chamber and said urine drain passage extends longitudinally in and substantially through the entire length of said device.

Claim 7

The incontinence device recited in claim 1, further including a urine discharge tube and a fluid intake tube, said urine discharge tube forming the urine conveying means of relatively narrow diameter to interconnect said inner tubular sheathing to said urine collection means, and said fluid intake tube connected between said inflatable fluid chamber and said fluid source means.

Claim 8

The incontinence device recited in claim 6, wherein said fluid intake tube, said urine discharge tube, and the drain end of said device are integrally connected to one another so as to be constructed as a single piece.

Claim 9

The incontinence device recited in claim 6, further including one-way fluid valve means, said one-way valve means particularly dimensioned so as to be positioned securely within said fluid intake tube between said fluid source means and said fluid chamber so as to control the supply of fluid therebetween.

Claim 10

The incontinence device recited in claim 6, further including a hollow insert particularly dimensioned so as to be positioned securely within said urine discharge tube between said urine drain passage and the urine collection means so that the user's urine is conveyed therethrough, the drain end of said inner tubular sheathing being retained in said urine discharge tube by means of said insert, whereby to cause said inner sheathing to constrict.

Claim 11

The incontinence device recited in claim 1, wherein said urine conveying means having a relatively narrow diameter is a urine discharge tube, the drain end of said inner tubular sheathing connected at the interior of said urine discharge tube whereby to cause said urine drain passage to constrict.

Claim 12

A male urinal having a tubular body portion and comprising: an elastic inner tubular sheathing adapted to receive a user's organ at a first end thereof and to expel the user's urine at a second end thereof, a flexible outer tubular sheathing connected to the inner sheathing at the first and second ends thereof and aligned in a substantially concentric relationship therewith so that an inflatable, annular fluid chamber is formed between said inner and outer sheathings and an axially extending urine discharge passage is formed at the interior of said inner sheathing, each of said fluid chamber and said discharge passage extending longitudinally and completely through the tubular body portion of said urinal so as to have substantially identical linear dimensions therein, means to substantially narrow the diameter of said longitudinally extending urine discharge passage at the second end of said inner tubular sheathing relative to the diameter of said passage at the first end of said inner sheathing, so that pooling of urine within said passage is substantially eliminated, and fluid duct means connected to said fluid chamber and adapted to supply fluid thereto for the purpose of inflating said fluid chamber and collapsing said inner sheathing under pressure around the user's organ, whereby air is evacuated from said urine discharge passage, so that an efficient liquid-tight seal is formed around the user's organ.

Claim 13

A male urinal having a tubular body portion and comprising: an elastic inner tubular sheathing adapted to receive a user's organ at a first end thereof and to expel the user's urine at a second end thereof, a flexible outer tubular sheathing connected to the inner sheathing at the first and second ends thereof and aligned in a substantially concentric relationship therewith so that an inflatable, annular fluid chamber is formed between said inner and outer sheathings and an axially extending urine discharge passage is formed at the interior of said inner sheathing, each of said fluid chamber and said discharge passage extending longitudinally and completely through the tubular body portion of said urinal so as to have substantially identical linear dimensions therein, means to substantially narrow the diameter of said longitudinally extending urine discharge passage at the second end of said inner tubular sheathing relative to the diameter of said passage at the first end of said inner sheathing, so that pooling of urine within said passage is substantially eliminated, and fluid duct means connected to said fluid chamber and adapted to supply fluid thereto for the purpose of inflating said fluid chamber and collapsing said inner sheathing under pressure around the user's organ, whereby air is evacuated from said urine discharge passage, so that an efficient liquid-tight seal is formed around the user's organ.

Claim 14

The male urinal recited in claim 11, wherein said means to narrow said urine discharge passage comprises hollow disc means having an outside diameter that is less than the diameter of the urine discharge passage formed by the first end of said inner tubular sheathing, the second end of said inner tubular sheathing interconnected with said disc means so as to convey the user's urine thereto via said urine discharge passage.
