And two pieces are opened near the leg side belt 36.

Two protrusions 33 are protruded from both longitudinal end surfaces of the rigid stretcher 32 on which the patient is placed, corresponding to the hooking holes 31 of the head belt 14 and foot belt 36, respectively.

The operation and method of use of this device having the above configuration will be described below.

A frame A in which a head side rail 2, a foot side rail 3, and two crosspieces 5 are framed to have a size comparable to the upper surface of the edge of the bathtub 1 is placed on the bathtub 1. Fixed piece 6 provided on the crosspiece 5
The frame body A is fixed to the bathtub 1 by bringing it into close contact with the upper inner wall of the bathtub 1. Ends of a head side rail 2 and a foot side rail 3 extending from the bathtub 1 toward a washing area adjacent to the bathtub 1 are supported by rail legs 4.

It consists of a head side base 8, a foot side base 9, a drive unit 11 placed on the head side base 8 and the foot side base 9, a head side winding roller 15, a foot side winding roller 19, etc. The elevating mechanism B is slid on the head side rail 2 and the foot side rail 3 and is pulled out to the front of a washing area or the like outside the upper surface of the bathtub 1.

When the handle 29 of the drive unit 11 is turned in one direction, the rotational speed is reduced by the worm gear box 27, and the rotational force is transmitted to the head side winding roller 15, the connecting shaft 22, and the foot side winding roller 19, Take-up roller 15 and foot-side take-up roller 19
The head side belt 14 and foot side belt 36 are unwound by the same length. At the same time, the stretcher 32 hooked to the ends of the head side belt 14 and the foot side belts 36 also descends while remaining in a horizontal state.

The patient is placed on the stretcher 32 by turning the handle 29 to lower the stretcher 32 and reaching the floor of the washing area.

Next, turn the handle 29 in the other direction to raise the stretcher 32 by winding the head side belt 14 and foot side belt 36 in the opposite direction to the above, and when the stretcher 32 reaches a position above the crosspiece 5, it is raised and lowered with the patient on it. Slide mechanism B onto the top surface of bathtub 1.

Turn the handle 29 in one direction and tighten the head belt 1.
The stretcher 32 is lowered by unwinding the leg belt 36 and the stretcher 32, and the patient and the stretcher 32 enter the hot water in the bathtub 1 to take a bath.

When taking a bath, turn the handle 29 in the other direction to wrap around the head belt 14 and foot belt 36 to raise the stretcher 32. When the stretcher 32 reaches above the crosspiece 5, the lifting mechanism B is moved up and down with the patient still on the bathtub. 1 Slide it toward the washing area outside the top surface.

Next, turn the handle 29 in one direction to unwind the head side belt 14 and the foot side belt 36, and move the stretcher 32.
The patient is lowered to the floor of the washing area, and the patient is lowered from the stretcher 32 to complete the bathing.

Appropriate brakes (not shown) for adding resistance to the rotation of the wheels 7 are provided at the front end 24 of the head side base and the front end 23 of the foot side base to prevent rotation of the wheels 7 when the stretcher 32 is raised or lowered. Prevents movement in the front-back direction.

When a patient is transferred to or from the stretcher 32, the horizontal support rod 25 pivotally attached to the front end 23 of the foot base is removed from the receiver 26 provided at the front end 24 of the head base, rotated in a fan shape, and raised upward. When a patient is on the stretcher 32, the horizontal support rod 25 is fitted and fixed to the receiver 26.

A frame body assembled into a rectangular shape with a head side rail 2, a foot side rail 3, and two crosspieces 5 has a distance between opposite sides thereof that can be appropriately varied according to the size of the rectangular bathtub 1. That is, the head side rail 2 and the foot side rail 3 are connected to the crosspiece 5 by screws, and the crosspiece 5 is constructed by providing a fixing bolt on a slide pipe material that can be expanded and fixed.

The effects of the present invention having the above configuration and operation will be described below.

A head rail and a foot rail are placed on the upper surface of both sides of the bathtub, and the lifting device installed on the head rail and foot rail is pulled out to the washing area, where the patient is placed on a stretcher lowered to the floor of the washing area. Since the bathing device is constructed so that the patient can be climbed on and off, the caregiver does not have to lift the patient to the bathtub edge height and then get the patient on and off the stretcher on the top of the bathtub, which greatly reduces the caregiver's labor.

In addition, the operation of the drive unit that raises and lowers the stretcher is either a handle type or a switch type when a motor and battery are used, so if the functional impairment of the upper limbs is mild, it is possible to raise and lower the stretcher and slide the lifting mechanism on your own. The patient receives only simple assistance from a caregiver, or
Or you can take a bath completely on your own. Therefore, the patient's concern for the caregiver decreases. In addition, for patients who are able to bathe on their own, this device allows them to do so freely, greatly contributing to home rehabilitation.

Furthermore, unlike conventional devices, this device does not require a heavy device such as a lift at the bottom of the bathtub, so the stretcher can be lowered until it touches the bottom, making it possible to take a sufficient bath without increasing the amount of hot water, making it suitable for general households. Not only was the bathtub enough, but it also gave rise to energy.

Furthermore, since the stretcher has a structure that allows the head and leg belts to be easily removed, the stretcher can be easily removed when cleaning the bathtub, eliminating the need to take heavy equipment in and out of the bathtub as with conventional devices. Cleaning can now be done easily without any equipment present.

Furthermore, since the head side rail and foot side rail are arranged at both ends of the bathtub, there are no obstructive utensils installed in the washing area, and the washing area can be used widely and sufficiently. In addition, when a healthy person from the same family is taking a bath, if the stretcher is removed from the head belt and foot belt, the device will be able to perform the bathing movements of the healthy person in the bathtub and in the washing area even if the device is placed in the bathtub. It is possible to take a bath without difficulty without causing any problems.
