Abstract

A basically conventional hospital bed is provided with one side portion of the intermediate length area of the mattress of the bed mounted from the bed frame for horizontal shifting toward a laterally outwardly projecting position in a manner such that an opening in the mattress is provided between the outwardly shifted side portion of the mattress and the opposite side portion of the mattress. The opening is generally centered relative to the opposite sides of the bed frame and a waste receiver is mounted beneath the mattress in registry with the opening. The receiver is mounted for vertical shifting between a lowered position beneath the mattress and a raised position projecting upwardly into the opening. The receiver includes a lower outlet for draining into a domestic sewer system or a holding tank and the inner periphery of the upper portion of the receiver is provided with a circumferentially extending manifold including outlets for discharging fluids downwardly along the walls of the receiver. Water supply means either in the form of a supply tank mounted from the bed at an elevation above the receiver or a domestic pressurized water supply is used to supply water to the manifold when desired.

Claims

1. A hospital bed including a support frame incorporating head and foot mattress portions and an intermediate mattress portion disposed between said head and foot portions, said mattress portions being supported from said frame, one side of said intermediate portion being mounted from said frame for lateral outward and inward shifting of said one side of said intermediate portion from the corresponding side of said frame to outer and inner positions with an opening formed through said mattress inwardly of said one side and between the latter and the other side of said intermediate portion when said one side is in the outer position and closing said opening when said one side is in said inner position, an upwardly opening waste receiver supported from said frame beneath said intermediate portion in position for vertical registry with said opening when said one side is in said outer position, mounting means mounting said receiver from said frame for from said frame for vertical shifting relative thereto between a lowered position disposed below said mattress and a raised position projecting upwardly into said opening, reversible motor means including forward and reverse directions of operation, first and second drive means operatively connected with said one side and receiver, respectively, for outer and inward shifting of said one side to said outer and inner positions and for raising and lowering said receiver to said raised and lower positions, respectively, and control means including a pair of bed patient manually actuatable operators, said control means, upon actuation of one of said operators, including means operative to actuate said motor means in the forward direction of operation thereof and drivingly connect said motor means to said first drive means to shift said one side from said inner position to said outer position and, in response to said one side reaching said outer position, to momentarily interrupt operation of said motor means, disconnect said motor means from said first drive means and drivingly connect said motor means to said second drive means and thereafter reestablish operation of said motor means in the forward direction of operation thereof to raise said receiver from said lowered position to said raised position and to terminate operation of said motor means upon said receptable being elevated to said raised position, said control means, upon actuation of the other operator, including means operative to actuate said motor means in the reverse direction of operation thereof with said motor means drivingly connected to said second drive means to lower said receptacle to said lower position from said upper position and, in response to said receptacle reaching said lower position, to momentarily interrupt operation of said motor means and disconnect said motor means from said second drive means and drivingly connect said motor means to said first drive means and thereafter reestablish operation of said motor means in the reverse direction to shift said one side inwardly from said outer position to said inner position and terminate operation of said motor means in the reverse direction upon said one side being shifted to said inner position.

2. The bed of claim 1 wherein the upper periphery of said receiver includes an elongated peripherally extending flushing water manifold mounted therein and including longitudinally spaced downwardly opening outlets for discharging water downwardly into said receiver, and water supply means for supplying water under pressure to said manifold.

3. The bed of claim 2 wherein said water supply means includes a water reservoir supported from said bed.

4. The bed of claim 3 wherein said water supply means is mounted on said frame at an elevation higher than said manifold.

5. The bed of claim 2 wherein water supply means includes means for ducting water under pressure from a pressurized domestic water supply.

6. The bed of claim 1 wherein said receiver includes a lower outlet, a holding tank mounted from said frame beneath said mattress, said outlet being communicated with said holding tank.

7. The bed of claim 1 wherein said receiver means includes a lower outlet and drain means operatively associated with said outlet for ducting waste material flowing from said outlet to a domestic sewer system.

8. The bed of claim 1 including a lower outlet depending downwardly from said receptacle with which the inlet end of a waste discharge pipe is communicated by a tubular telescopic connecting sleeve assembly.

9. The bed of claim 1 wherein said head, foot and intermediate mattress portions are separately formed.
