Description

  The present invention relates to a transfer device that supports a transfer operation when a person who uses a wheelchair for living because it is difficult to walk independently, and performs a transfer operation from a wheelchair to a bed or a toilet.

  Caregivers who are forced to live in a wheelchair because of difficulty in walking independently cannot easily move from a wheelchair to a chair, bed, or toilet, and need assistance from the caregiver. And However, this transfer assistance is to move the cared person while supporting the weight of the cared person, which is a physical burden on the carer.

  Therefore, for example, the following methods have been proposed as transfer means for supporting transfer of a cared person from a wheelchair to a chair, bed, toilet, car seat, or the like.

  In the method disclosed in Patent Document 1 (Japanese Patent Laid-Open No. 09-140746), the sling sheet is laid between the seat and the buttock, and the cared person is wrapped in the sling sheet and lifted by the lift mechanism and transferred. It is a method to do.

  In the method disclosed in Patent Document 2 (Japanese Patent Laid-Open No. 2011-92324), the upper body of the cared person is held by a body holder provided on a movable carriage, and thereby the posture of the cared person is changed. This is a method of supporting and transferring in a forward bent state.

  In the method disclosed in Patent Document 3 (Japanese Patent Laid-Open No. 2001-17485), a seat is inserted below the thigh of a cared person in a sitting state, and the back of the cared person is supported by the back receiving part. On the other hand, the thigh is lifted and moved by the lifting function of the seat.
