Abstract

A mattress apparatus for incontinent patients includes first and second resilient mattress portions each having a sloping end and a water repellent cover attached thereover. The covers are removably attached together to form a mattress. A liquid drain cover is made of a flexible, water repellent material and has first and second sections and is shaped to fit over the connected first and second resilient mattress portions. Each section of the liquid drain cover has a plurality of elongated ridges extending thereover and forming a plurality of drain grooves therebetween. The drain cover has a liquid collection channel formed between the first and second sections for collecting liquid draining from. The liquid collection channel located between the drain cover sections is connected to a liquid collection container for collecting liquid from the channel. The drain cover has a beaded edge around three sides of each section to block the escape of liquid therefrom. An alternative embodiment has first and second resilient body support members having a plurality of ridges and valleys formed therein. Another embodiment has an air tube located in the drain cover grooves so that air escaping from openings in the tube cools and dries the patient using the mattress. Vacuum tubes are also used to remove collected liquid on the drain cover.

Claims

1. A mattress for incontinent patients comprising:

a first resilient mattress portion having top and bottom sides and having first and second end portions, said first end portion having an angled surface, said first resilient mattress portion having a water repellent cover;

a second resilient mattress portion having top and bottom sides and having first and second end portions said first end portion having an angled surface, said second resilient mattress portion having a water repellant cover;

a plurality of attaching members for removably attaching said first and second resilient mattress portions together to form a body supporting mattress;

a liquid drain cover made of a flexible, water repellent material and shaped to fit over said connected first and second resilient mattress portions, said liquid drain cover having first and second sections, each section having a plurality of elongated ridges extending thereover and forming a plurality of drain grooves therebetween, said drain cover having a liquid collection channel formed between said liquid drain cover first and second sections for collecting liquid draining from said drain cover grooves; and

a liquid collection container connected to said liquid drain cover collection channel to receive liquid from said liquid collection channel, whereby a bedridden patient'"'"'s urine is directed from each said drain cover section into said collection channel and collection container.

2. A mattress for incontinent patients in accordance with claim 1 in which said drain cover plurality of ridges are formed of a foamed polymer.

3. A mattress for incontinent patients in accordance with claim 1 in which said plurality of ridges are formed of a foamed polyurethane.

4. A mattress for incontinent patients in accordance with claim 2 in which said drain cover liquid collection channel has a stainless steel tube connected thereunder and attached thereto.

5. A mattress for incontinent patients in accordance with claim 2 in which said first and second resilient mattress portions are each formed of a foamed polymer.

6. A mattress for incontinent patients in accordance with claim 5 in which each said foamed polymer resilient mattress portion is polyurethane.

7. A mattress for incontinent patients in accordance with claim 1 in which said liquid drain cover is made of a flexible waterproof fire retardant polymer.

8. A mattress for incontinent patients in accordance with claim 1 in which said first and second water repellant cover each have a zipper thereon for sealing each said cover over one resilient mattress portion.

9. A mattress for incontinent patients in accordance with claim 1 in which each said liquid drain cover section plurality of ridges extend over one end of each said first and second resilient mattress portion.

10. A mattress for incontinent patients in accordance with claim 1 in which said plurality of attaching members are hook and loop fasteners.

11. A mattress for incontinent patients in accordance with claim 1 having a flexible tube connecting said liquid collection channel and said liquid collection container.

12. A mattress for incontinent patients in accordance with claim 1 in which each said liquid drain cover liquid collection channel has edge tabs at each end thereof to prevent escape of liquid collected in said liquid collection channel.

13. A mattress for incontinent patients in accordance with claim 4 including a plurality of tube fasteners connected between said stainless steel tube and each said first and second resilient mattress portion water repellant cover to hold said stainless steel tube and liquid collection channel in place between drain cover first and second sections.

14. A mattress for incontinent patients in accordance with claim 1 in which each said first and second resilient mattress portions water repellant covers has a plurality of handles attached thereto.

15. A mattress for incontinent patients in accordance with claim 1 in which each said drain cover first and second sections has a beaded edge around the periphery of three sides thereof.

16. A mattress for incontinent patients in accordance with claim 1 including a air tube having a plurality of opening therein positioned in said drain cover grooves and said air tube being connected to a source of pressurized air for forcing air through said tube and through said plurality of openings in said tube whereby forced air cools a patient and dries moisture collected on said drain cover.

17. A mattress for incontinent patients in accordance with claim 16 in which said air tube has a plurality of star cuts therein.

18. A mattress for incontinent patients in accordance with claim 16 including a vacuum tube positioned on said drain cover and having a negative pressure place thereon for removing liquid collected on said drain cover.
