Description

The present invention relates to an improvement of a transfer device used when a person who has difficulty walking is transferred from a bed to a wheelchair or the like.

In general, in nursing care facilities, when bathing care recipients who are difficult to walk, place the caregiver sleeping in the bed on a wheelchair, transfer them to the undressing in the special bathtub room, and place them on the bed for undressing. The bath is replaced with a stretcher, a wheelchair or a lift for bathing. In this case, the caregiver holding the care recipient who is sleeping on the bed with two people, and the caregiver who is replacing the wheelchair for bathing requires physical strength and has a heavy burden on the waist This is hard work for the caregiver. In addition, care recipients could bruise when they were holding them, causing great pain.

For this reason, various transfer instruments have been developed, but an apparatus for transferring with a small force by applying the lever principle has also been proposed. For example, a main pillar is erected on the left and right sides of a pedestal having casters, a curved rotary shaft is attached to the upper side of the main pillar, and a curved mat body is integrally attached to the rotary shaft via a brake gear. A transfer device (Patent Document 1) has been developed in which an operation handle is provided on the front end side of the mat body, and a receiving plate is provided on the rear end side to support the buttocks.

This transfer device has a shape in which the mat is curved like a person's back, and the transferee (caregiver) is held on his / her face like a child who is lying on his face, When the assistant lowers the operation handle, the transfer person who leans against the mat with a small force can be lifted and moved as it is based on the lever principle.

However, in this transfer device, the transferer is lying on the curved mat and moves, so that there is a risk of the chest being compressed and the ribs fractured in elderly people with weak bones.

For this reason, two rotating struts are rotatably erected on the left and right sides of the base frame to which the casters are attached, and arm support members are respectively attached in parallel to the upper portions of the left and right rotating struts. A stopper that restricts the rotation range of the rotating column on the base frame is provided with an operation handle on the front end side of the supporting member, a gripping rod protruding from the middle portion, a thigh supporting portion suspended from the rear side of the arm supporting member. And the footrest part is provided, and the rear side of the left and right arm support members is inserted from the armpit of the transferor to support the lower side of the transferor's thigh with the thigh support part, and then the foot of the transferor is There has also been developed a transfer device (Patent Document 2) in which an assistant lowers an operation handle and lifts and moves a transferer according to the principle of lever while being placed on a mounting portion and holding a gripping rod by hand.

This transfer device allows the assistant to lower the operation handle and lift the mover according to the principle of leverage, and when sitting on a chair, etc., raise the operation handle to allow the transferer to sit with less force according to the principle of leverage. Can reduce the burden on the caregiver. In addition, since the chest of the transferee is not compressed, it can be transferred in an easy posture. Moreover, there is an advantage that the structure is simple and small, and can be manufactured at low cost.

However, in this transfer device, during the transfer, the assistant has to move with the operation handle lowered, which is a burden on the assistant.

For this reason, a transfer device using a motor has also been developed. For example, a base part installed opposite to a wheelchair, a moving base provided so as to be movable in the vertical and horizontal directions with respect to the base part, and a guide bar provided on the moving base And a guide bar is inserted into a seat seat with a hole between the human body and the wheelchair, the human body is moved up and down to float from the wheelchair, and the human body is moved in the horizontal direction to A transfer device (Patent Document 3) for seating at a destination has been proposed.

This transfer device uses a motor to move the guide bar up and down and rotate horizontally, making it easy to move from the bed to the wheelchair and get on the car. Since it rides, it can be used only by a relatively mild care recipient and there is a problem of poor stability because there is no device for fixing the body.
