Slick  ABSTRACT A hospital patient care unit is provided which consists of a folding toilet in a compact cabinet wherein the bowl of the toilet is removable so that the unit can be used either as a bedpan or in the normal manner. The unit is designed so that when it is closed, the bowl is automatically flushed and washed out and an interlock prevents opening the cabinet while the flushing operation is taking place.
3 Claims, 5 Drawing Figures HOSPITAL PATIENT CARE UNIT SUMMARY OF THE INVENTION The present invention relates to a hospital care unit which consists of a toilet which folds into a cabinet. The bowl portion of the toilet can be removed and used separately as a bedpan. When the bowl is in position the cabinet can be closed whereupon the unit automatically flushes and washes out the bedpan. An automatic interlock prevents opening the cabinet while the flush ing operation is taking place.
The unit is very compact and in a preferred embodiment of the invention extends outwardly only one foot from the wall on which the unit is mounted while the cabinet is in the closed position.
It is relatively inexpensive and encourages patients to take care of their own needs as early as possible and minimizes personnel work load. I
In coronary care rooms a patient is wired to wall mounted instruments near his bed. As his condition improves he is encouraged to become ambulatory and the proximity of the HPC unit to his bed permits use of the unit as a toilet.
The unit lends itself to being combined with a lavatory so that all of a rooms plumbing needs can be taken care of in one compact unit. Since the bowl or convenience receptacle is removable, it lends itself to ready use for stool examination and provides a simple means for measuring a patients output in coronary care rooms where the intake and output is important to diagnosis and treatment. The convenience receptacle is preferably formed of stainless steel and is easily sterilizable.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a perspective view of a patient care unit embodying the present invention showing it in the open position.
FIG. 2 is a side view of the unit shown in FIG. 1, partly in section.
FIG. 3 is a front view on the line 3-3 of FIG. 2.
FIG. 4 is an enlarged sectional view on the line I4 of FIG. 3 of the interlock which prevents opening the unit while the flushing operation is taking place.
FIG. 5 is a piping diagram of the flushing unit.
DESCRIPTION OF THE PREFERRED EMBODIMENTS Referring now to the drawings by reference characters, the unit of the present invention is housed in a cabinet having a front panel 5, with access panelsfi and 8. The cabinet also includes side panels 7 and 9 and a top work surface 11. The top surface 11 may be provided with the usual lavatory fittings, including a washbowl, all generally designated 13. At the front of the cabinet an opening 15 is provided and near the bottom of this opening a support member 17 is mounted by means of a hinge 19 with spring loaded hinge pin 20 to permit removal for thorough cleaning. Support unit 17 is mounted in such a manner that when it is in a closed position it will lie flush with the front panel 5 and thus forms a door. Uprights 21 support a toilet seat 23 which is provided with the usual hinge mounting 25. A bedpan or convenience receptacle 27, preferably formed from two pieces of stainless steel, is provided which rests on the support frame 17 and is held in position by pins 29 and the support arms 21. Receptacle 27 is not fastened down so that it is readily removed for use in another location, yet is held in the desired place by the means described. At the front of support member 17 a hole 31 is provided which serves to lock the support member in the upright or closed position while the flushing action is taking place as is hereinafter described in detail.
Mounted within the cabinet is a standard flush valve 33 which is connected by suitable piping 35 through stop valve 36 to a water source, not shown. The flush valve includes the usual pushbutton 37 which is actuated by pressure from the toilet seat 23 when it is in the upright position as is best seen in dot dash lines in FIG. 2. A first pipe 39 leads from the flush valve through a vacuum breaker 40 to a central nozzle 41 and bottom nozzles 43 and 45 which squirt against the convenience receptacle thoroughly flushing it and washing the contents down the drain. To further assist in the flushing operation, a nozzle 47 is provided in trap 49 so that any solid matter is positively washed from the trap. The top of the trap 49 is enlarged as at 51 for the reception of the material from the convenience unit. Another line 53 leads from flush valve 33 to interlock 55. Interlock 55 consists of a cylinder 57, having a piston 59 mounted for reciprocation therein, the piston being normally held in the up position by a spring 61. A pin 63 extends downwardly from piston 59 and when water pressure is applied through line 53, pin 63 is driven downwardly into the hole 31, positively locking support member 17 in the closed position. This prevents any splashing from the unit which might result in soiling the clothes of a person who actuated the flushing operation. After the flushing operation is complete, the pressure falls in line 53, allowing pin 63 to move upardly, releasing the support member 17 so the unit is now ready for a repetition of the operation.
It is believed apparent from the foregoing that l have provided a hospital patient care unit which occupies little space, which is simple in construction and which can be used as an ordinary toilet or as a flushing unit for a .bed pan.
