In order to bathe a patient who has entered the bathroom in a wheelchair, the hot water and water mixing supply lever 60, the faucet opening/closing button 61, and the bubble generation button 62 are operated in advance.

Then, the stretcher 38 is moved to the outside of the cleaning tank 5 using the left movement button F and stopped using the stop button E, and then the stretcher is lowered below the wheelchair seat plate using the down button A and stopped using the button B.

The patient can be easily transferred to the stretcher, and it is also easy to transfer to the stretcher without the patient on the floor.

When the patient lies supine on the stretcher, the stretcher is raised by the lift button C, and when the stretcher reaches a position slightly higher than the cleaning tank 5, the stretcher stops raising by the limit switch 55.

Then, when the stretcher moved by the right movement button reaches directly above the cleaning tank 5, the limit switch 34 contacts a cam (not shown) and stops.

In this position, the caregiver washes with soap and water using an appropriate shower.

The cleaning wastewater is discharged from the drain pipe 66 of the cleaning tank 5.

When the patient is washed, the stretcher is moved by pressing the right move button, and when it reaches just above the bathtub, the limit switch 34 is activated to move the dog 33.
Stops when it comes into contact with.

When the stretcher is then lowered using the lowering button A, the dog 56 comes into contact with the limit switch 57, and the stretcher stops lowering at an appropriate immersion position in the bath water.

When the patient has finished taking a bath, the stretcher is raised with the rise button C, stopped with the limit switch 55 and the dog 54, and the stretcher is moved towards the wiping tank with the right move button, and the cam (
(not shown), then take a shower, wash with hot water, and then wipe.

After cleaning the patient, the stretcher is moved to the right outside of the cleaning tank 6 using the right move button, stopped using the stop button E, and then pressed the down button A.
Lower the wheelchair to the seat position and stop it using button B.

Then, with the assistance of a nurse, the patient was transferred to a wheelchair and returned to the hospital bed.

When a series of bathing operations for a patient are completed, the stretcher is moved to the left and the next patient is bathed.

Alternatively, the second patient may be transferred to the stretcher at the position where the first patient is bathed and transferred to the wheelchair, and the second patient may be moved in the opposite direction before being bathed.

Therefore, the cleaning tank 5 and the wiping tank 6 are formed to have exactly the same structure.

Although the above-mentioned movement and elevation of the stretcher were mainly operated manually using buttons A to F, it is easy to automatically operate all operations of the stretcher by incorporating an electrical sequence control circuit.

The present invention, which has the above-mentioned functions, eliminates the frequent labor required by nurses to precisely connect the elevating frame in the bathtub and the transport vehicle, and to push the stretcher and align it on each tank, unlike conventional devices. The stretcher can be moved up and down simply by pressing buttons, and other nurses can concentrate on washing and wiping the patient's body.

Furthermore, in the past, it was not possible to take a hot bath without placing a stretcher on a transport vehicle, but with this device, a hand-driven wheelchair with a seat board lower than the transport vehicle or, if necessary, a hand-driven wheelchair can be used to transfer the patient to the stretcher from the bathroom floor using its own blade. Therefore, almost all non-ambulatory patients admitted to hospitals etc. can take a bath in hot water, and it is possible to omit the number and labor of nurses.

In addition, by installing a washing tank and a wiping tank on both sides of the bathtub, it became impossible for nurses to wash the patient in the bathtub even if they reached out. (None) If you then take a bath in the bathtub after rinsing with hot water, there is no need for a nurse to clean the bathtub, the bathtub water will not be contaminated, and the same bathwater can be used for many patients.
It is possible to reduce the number of times hot water needs to be replaced.
