ABSTRACT:
A compact and inexpensive air catheter having particular application as an improved male incontinence device. The catheter herein disclosed includes a relatively thick outer tubular sheathing and a collapsible, relatively thin inner tubular sheathing. Inner and outer sheathings are concentrically arranged relative to one another. The region of the catheter between the inner and outer sheathings forms an annular air chamber, which chamber is adapted to be inflated, under pressure, in order to collapse the inner sheathing around a user's organ, whereby an efficient air and liquid-tight seal is formed therewith, regardless of the shape or size of the organ. The region of the catheter that is defined by the interior of the inner sheathing forms an axially extending urine drain passage for the purpose of conveying the user's urine to an external urine collection means. During operation, the drain passage is substantially air evacuated, whereby the possibility of urine backflow thereto, under the influence of gravity, from the collection means is substantially eliminated.
