US 4,747,166 A · Fluid aspiration system for the management of urinary incontinence

Abstract

A urine aspiration system for the management of urinary incontinence comprising an absorptive pad adapted to temporarily receive and retain urine until it is drawn from the pad by an associated vacuum source. The pad comprises an absorptive core encased within a covering of hydrophobic material such as polyethylene sheet material. The upper cover sheet of the casing has a myriad of perforations to render it permeable to liquid, while the lower backing cover sheet is impermeable. Tubing from the vacuum source is coupled to a central opening of the pad so that urine may be readily drawn out of the pad when the vacuum source is activated, leaving the outer covering of the pad feeling dry and comfortable to the patient. A collection vessel is mounted between the vacuum source and the pad to collect the urine drawn from the pad.

Dependent claims

A system for the receiving and disposing of human urine excreted from an incontinent patient comprising:

(a) an absorptive pad adapted to be placed adjacent the urinary opening of an incontinent patient, said pad having an inner core of urine-absorptive material, an upper pad facing layer of liquid-permeable hydrophobic material in contact with said patient in the area of said opening, and a lower pad backing layer of impermeable material, and said pad enclosing a flexible perforated tube extending over the length of said pad and having a fluid outlet connector means at one end thereof adjacent an edge of said pad;
(b) a vacuum source;
(c) a urine collection vessel;
and
(d) vacuum tubing coupling said flexible perforated tube within said pad to said collection vessel and coupling said collection vessel to said vacuum source whereby urine from said patient entering said absorptive pad through said facing layer is drawn through said absorptive pad to said perforated tube and to said collection vessel.

A system for the receiving and disposing of human urine excreted from an incontinent patient comprising:

(a) a flexible absorptive pad adapted to be placed adjacent the urinary opening of an incontinent patient, said pad having an inner core of urine-absorptive material with a central bore extending over a major portion of the length thereof, an upper pad facing layer of liquid-permeable hydrophobic material in contact with said patient in the area of said opening, a lower pad backing layer of impermeable material, and a fluid outlet connector means at one end of said pad adjacent an edge thereof and in fluid flow communication with said bore;
(b) a vacuum source;
(c) a urine collection vessel;
and
(d) vacuum tubing coupling said outlet connector means of said pad to said collection vessel and coupling said collection vessel to said vacuum source whereby urine from said patient entering said absorptive pad through said facing layer is drawn through said absorptive pad to said central bore and from said central bore through said outlet connector means and said tubing to said collection vessel.
