The effects of this device with the above-described configuration and operation will be described below.

In a typical home where healthy family members and patients live together, this device can be extremely easily attached to and removed from an existing home bathtub.

In addition, this device and the stretcher can be easily attached and detached, so when a healthy family member takes a bath after the patient has taken a bath, the lightweight stretcher can be removed and the hanging belt should be fully wound around the rollers before taking a bath. Alternatively, since the stretcher can be lowered to the lower limit position before taking a bath, the bathtub can be shared by family members and the patient very easily.
Furthermore, since the stretcher can be easily removed, the inside of the bathtub can be cleaned easily without having to remove the entire device, which has the effect of reducing the labor of family members.

In addition, the stretcher is made rigid so that it does not deform, making it much easier for patients to transfer. Since the stretcher does not deform when going up and down, the patient can take a bath in any position without being in a cramped position, making it very easy to take a bath.Also, the lower body of the stretcher is always maintained horizontally and does not move in parallel in the vertical direction. Since the stretcher is securely held by a wide hanging belt, the stretcher is stable and does not sway, allowing the patient to take a bath with peace of mind.

Furthermore, the frame on the transfer side of the frame of this device is made of a thin plate and has few steps, making it easy for elderly people and patients with muscular atrophy to transfer, which has the effect of reducing the labor of the caregiver.

In addition, bathing operations can be easily performed by simply turning a handle that rotates smoothly with low torque, and the stretcher can be stopped at an appropriate position according to the patient's body position, making it safe and free from the possibility of erroneous operation.

In addition, the stretcher moved smoothly during the lifting and lowering operations, and the operating noise of the device was quiet.The appropriate cushioning material placed on the top of the stretcher did not cause any discomfort when it came into contact with the patient's skin, allowing the patient to bathe comfortably. It is.

Moreover, if the existing bathtub is a recessed type, it will be even more effective. That is, when transferring the patient to or from the stretcher, the effort of the caregiver to lift the patient is reduced.

In addition, if the existing bathtub has a high edge, in addition to this device installed in the bathtub, place one side of this device against the outer wall of the bathtub in the bathing direction, and also set the four corners of the frame at the same height as the bathtub edge. It is also possible to use it by supporting it with appropriate legs and placing it on the floor outside the bathtub.
That is, it is also possible to use the device simply as a device for lifting and lowering a patient. In this case, the patient is transferred to and from the stretcher by passing under the frame.

This device, which has the above-mentioned effects, is ideal as a bathing facility for rehabilitation in ordinary homes (home rehabilitation) where patients and their family members live together.
