Abstract

A bed, in combination with a flush toilet, has a bed body (1) provided with an opening (2). The opening has a width which is sufficient to accommodate the hips of a sick or disabled person laying on the bed. The opening (2) can be opened and closed by a cover (4). The cover can be withdrawn from a retracted (open) position where it is accommodated on the back of the bed body (3) to close the opening (2). A flush toilet (8) is disposed below the opening (2). A toilet seat (8) is disposed in the opening and has a somewhat cylindrical excreta guide (9) for reliably guiding excreta into the flush toilet (8). The toilet seat (7) can be tilted about a vertical axis by a lift (10). Also, the toilet seat free end is tilted upward so as to be in close contact with the hips of the sick or disabled person.

Claims

1. A bed for a sick or disabled person, said bed comprising:

a bed body for supporting the sick or disabled person, said bed body having an opening extending through an intermediate portion of said bed body;

a flush toilet disposed below said opening;

a toilet seat disposed in said opening and pivotally connected to said bed body so as to be adjacent to the hips of the sick or disabled person during use;

a collecting structure connected to said toilet seat and extending outwardly therefrom, said collecting structure having an outer periphery defined by upwardly projecting peripheral walls;

a guide depending from an outer periphery of said toilet seat for guiding excreted matter into said flush toilet; and

a cover for selectively opening and closing said bed body opening, wherein said cover is slidably disposed over said bed body opening, and said cover is retractable from a closed position covering said bed body opening to an open position at which said cover is wound in a roll below an upper lever of said bed body.

2. The bed as claimed in claim 1, further comprising:

a flexible water supply tube for supplying water to said flush toilet; and

a flexible drain tube for conducting drainage from said flush toilet.

3. The bed as claimed in claim 2, further comprising a water supply tank connected to an end of said flexible water supply tube, wherein said water supply tank is disposed at a level which is higher than that of said flush toilet.

4. The bed as claimed in claim 1, further comprising a urine extractor which includes:

a tube extending through said collector, said tube having a first end and a second end which extends into said flush toilet; and

a funnel-like member connected to said first end of said tube, said funnel-like member being located in the vicinity of said toilet seat.

5. The bed as claimed in claim 4, wherein said urine extractor includes an electric conduction sensor means or an ammonia sensor means for detecting the presence of urine.

6. The bed as claimed in claim 1, further comprising:

a water tank in communication with said flush toilet;

a sensor provided on one of said flush toilet and said toilet seat for detecting defecation or urination by the sick or disabled person; and

a water supply controller, disposed between said sensor and said water tank, for causing water to be supplied from said water tank to said flush toilet in response to a detection signal emitted from said sensor.

7. The bed as claimed in claim 6, wherein said sensor is provided on said toilet seat.

8. The bed as claimed in claim 1, further comprising a lifting mechanism connected to a free end of said toilet seat for pivoting said toilet seat upwardly into contact with the hips of the sick or disabled person.
