  However, the methods (1) to (4) have the following problems.

(1) Method problem Since the bathtub frame is provided in the bathtub, when a bather capable of straddling the bathtub tries to take a bath, the bathtub frame and its frame obstruct the bathing, and the degree of care In a care facility where there are a plurality of different care recipients, the bathtub frame and its frame must be taken in and out depending on the degree of care.
Because special bathtubs are used, it is difficult to adopt them in ordinary households and small nursing homes.
In addition, when bathing, the water level of the bathtub must be raised and lowered, so that it takes time to adjust the water level and the care work is complicated.

(2) Problem of the method Because the seat is slid in the direction of the caregiver's foot so that the seat faces the bathtub,
In the case of a small bathtub, a lift device cannot be installed.
In other words, in the case of a general household with only a small bathtub or a small nursing facility, only one long side of the rectangular bathtub faces the washing area, all the other faces the bathroom wall, and the other washing area side. A lifting device must be attached to the bathtub wall.
However, in the case of a small household bathtub, a lift device cannot be installed because the length of the lift table cannot be secured.
Therefore, it is costly, such as performing bathroom expansion work.

Problem (3) When a horizontal rail is attached to the wall of an existing bathroom, it is necessary to reinforce the wall, which is expensive.
Moreover, care recipients must be transported to a bathroom with another wheelchair or the like, and the care recipient must be transferred to the chair portion of the lift chair unit in the bathroom, which makes the care work complicated.
Moreover, in nursing facilities where many people take a bath, the floor of the bathroom may get wet when changing trains, and the caregiver slips on the feet when changing caregivers and the caregiver is injured. There is a risk.

Problem (4) Since it is necessary to attach a ceiling lift to the ceiling, the ceiling must be reinforced. Therefore, a large-scale construction is required and costs are high.
Also, since the lift device lifts and lowers the belt suspended from the arm, the height of the ceiling must be increased to lift the care receiver 's toes that hang down from the chair to a height over the buttocks of the bathtub. I must. In other words, even if a lift device can be installed at a ceiling height as in a general household, the toe side of the cared person must be lifted so that the toe side of the cared person will get over the buttocks of the bathtub. I must. Therefore, the caregiver is burdened and the care recipient may be in an unstable posture.

  In view of the above circumstances, the present invention can transfer a cared person while sitting on a chair to the side of a bathtub or a toilet without incurring remodeling costs for a bathroom or toilet for general households, and An object of the present invention is to provide a nursing care transfer device that can be used for bathing and stool without being transferred from the chair portion.
