Abstract

A liquid discharge unit having a toilet tray with drainage at the bottom of the tray. Tubing extends from this drainage to a collection vessel. The tray has an upper open surface covered by a non-corrosive nylon net. The net has above it sealed foam blocks and an outer sealed cell foam sheet to facilitate comfort to the patient and to provide a lying surface that will minimize the formation of decubitus ulcers.

Claims

1. A liquid discharge unit comprising a toilet tray, a supporting surface and disposal means, said toilet tray comprising a top open portion and at least one opening in its lower portion, said toilet tray having positioned above said top open portion said supporting surface, said supporting surface comprising a substantially non-corrosive supporting net, said tray having said drain openings in its said lower portions which are adapted to facilitate the flow of liquid therethrough to a disposal means, positioned above and supported by said net is at least one sealed cell foam block, positioned above said block is a sealed foam sheet having apertures therein to provide conduits for liquids to pass therethrough and eventually to said disposal means.

2. The unit of claim 1 having two blocks, each of said blocks being positioned in such a manner that a space is provided therebetween for the passage of liquids.

3. The unit of claim 1 wherein said drain openings are provided with liquid-tight means from which the liquid drains into a collection vessel.

4. The unit of claim 1 wherein said tray comprises drain openings connected to flexible tubing means, said tubing means extending from said openings to a collection vessel having a removable lid portion.

5. The unit of claim 1 having three blocks of sealed convoluted foam, each block separated by a space sufficient to permit the passage of liquid therethrough, said space extending vertically from said sheet to said net.

6. The unit of claim 1 wherein said sealed cell foam sheet is liquid-sealed to prevent the absorption of liquid in the foam pores and to facilitate the passage of liquid through the apertures therein, said apertures being in flow relationship to said block spaces.

7. A liquid discharge unit comprising a toilet tray, a supporting surface, and liquid disposal means, said toilet tray comprising a top open portion and lower corner portions with openings in said lower corner portions, said toilet tray constructed of a non-metallic material and comprising in each of its said lower corner portions drain means, said tray having its top open portion substantially covered by said supporting surface, said supporting surface comprising a substantially non-corrosive supporting net which is removably attached to the top portion of said tray, positioned above said net are liquid-sealed foam blocks having spaces therebetween to permit the passage of liquid therethrough to a collection vessel positioned above said blocks is a liquid-sealed cell sheet having apertures therein to further permit the passage of liquid therethrough, said liquid disposal means comprising flexible tubes extending from said drain means to said collection vessel.

8. The unit of claim 7 having two blocks, each of said blocks being positioned in such a manner that a space is provided therebetween for the passage of liquids.

9. The unit of claim 7 wherein said drain openings are provided with liquid-tight means from which the liquid drains into a collection vessel.

10. The unit of claim 7 wherein said tray comprises drain openings connected to flexible tubing means, said tubing means extending from said openings to a collection vessel having a removable lid portion.

11. The unit of claim 7 having three blocks of sealed convoluted foam, each block separated by a space sufficient to permit the passage of liquid therethrough, said space extending vertically from said sheet to said net.

12. The unit of claim 7 wherein said sealed cell foam sheet is liquid-sealed to prevent the absorption of liquid in the foam pores and to facilitate the passage of liquid through the apertures therein, said apertures being in flow relationship to said block spaces.

13. A sanitary mattress comprising a substantially centrally located cut out portion adaptable to house a liquid discharge uit, said liquid discharge unit comprising a toilet tray, a supporting surface and disposal means, said toilet tray comprising a top open portion and lower corner portions with openings in said lower corner portions, said toilet tray having positioned above said top open portion said supporting surface, said supporting surface comprising a substantially non-corrosive supporting net, said tray having drain openings in each of its said lower corner portions which are adapted to facilitate the flow of liquid therethrough to a disposal means, positioned above and supported by said net is at least one sealed liquid tight foam block, positioned above said block is sealed cell foam sheet having apertures therein to provide conduits for liquids to pass therethrough and eventually to said disposal means.

14. The mattress of claim 13 wherein said liquid discharge unit has two liquid tight blocks, each of said blocks being positioned in such a manner that a space is provided therebetween for the passage of liquids.

15. The mattress of claim 13 wherein said drain openings are provided with liquid-tight means from which the liquid drains into a collection vessel.

16. The mattress of claim 13 wherein said tray comprises drain openings connected to flexible tubing means, said tubing means extending from said openings to a collection vessel having a removable lid portion.

17. The mattress of claim 13 having three blocks of sealed liquid tight convoluted foam, each block separated by a space sufficient to permit the passage of liquid therethrough, said space extending vertically from said sealed cell foam sheet to said net.

18. The mattress of claim 13 wherein said sealed cell foam sheet is liquid-sealed to prevent the absorption of liquid in the foam pores and to facilitate the passage of liquid through the apertures therein, said apertures being in flow relationship to said block spaces.
