Abstract

The present invention enables a bedridden person to perform excretory functions without help from another person. The present invention includes a bed and a movable toilet in which water is provided. A negative pressure propels water and excrements through a bottom hole in a lower part of the toilet, through a valve and to a sanitary container.

Claims

1. An excretion apparatus and bed for bedridden people, comprising;

a sleeping pad;

a toilet having a mat on a top surface of said toilet, wherein a top surface of said mat is level with a top surface of said sleeping pad when said toilet is in a lowered position;

a sanitary container communicating with said toilet;

an openable cover for overlaying an upper opening of said toilet;

a means for generating a negative pressure between said toilet and said sanitary container, wherein said negative pressure delivers excrements and fluid from said toilet to said sanitary container; and

a means for positioning said toilet at said lowered position and for lifting said toilet to a raised position when said toilet is in use.

2. An excretion apparatus and bed as claimed in claim 1, wherein a safety mechanism prevents said toilet from lowering when said cover is in an open position.

3. An excretion apparatus and bed as claimed in claim 1, further comprising:

a valve between said toilet and said sanitary container;

wherein said safety mechanism prevents said valve from opening when said cover is in said open position.

4. An excretion apparatus and bed as claimed in claim 1, wherein said safety mechanism prevents said negative pressure from delivering said excrements and fluid when said cover is in said open position.
