Description

Standing chair for assistance and assistance method

The present invention relates to an assistance standing chair and an assistance method for assisting a person to be assisted who has weak legs and loins to at least stand up and assume a standing posture.

Various rehabilitation attempts have been made for caregivers who are unstable or difficult to stand up on their own, and for caregivers who are unstable in a standing posture. In particular, for training performed in a standing position, a large amount of manual assistance by the caregiver is required to safely support the person being assisted, and there are cases where effective training support cannot be provided by the caregiver who is weak. .

Therefore, conventionally, devices have been considered to reduce the amount of assistance required in training performed in a standing position. A stand-up training bed, in which an actuator interposed between the beds is used to rotate the bed around the one end to raise the person to be assisted, is the mainstream (Patent Document 1). However, this stand-up training bed requires the person to be assisted to hold onto a handrail while leaning against the bed to support the body, and there is room for improvement in terms of the stability of the support.

In addition, when assisting the use of a stool-type toilet, not only assisting with sitting, but also undressing (lowering trousers and pants, rolling up the hem of a dress or yukata) and dressing (trousers and pants) movement, such as raising the skirt and lowering the hem of a dress or yukata). Undressing and dressing is difficult when the buttocks are in contact with the toilet seat, and is possible by supporting the care recipient in a standing posture with the buttocks floating above the toilet seat so as not to collapse.

However, the conventional lifting devices for toilet assistance (Patent Documents 2 and 3) assist the person being assisted in slowly sitting on the seat-type toilet, and support the person being assisted in a standing posture so that they do not collapse. did not have the ability to With only the armrest of Patent Document 2 and the armrest member of Patent Document 3, the legs and lower back of the care recipient in particular tend to collapse, and the upper half of the body may also fall forward. For this reason, while the caregiver supports the care recipient with his or her arm, another caregiver needs to assist the care receiver in undressing and dressing, which is both hard work and difficult work.

Alternatively, separately, a so-called standing lift (Patent Documents 4 and 5) is used to make the person being assisted stand up, and in that state, the person being assisted is assisted in undressing. It is also conceivable to assist the patient in sitting down. However, it increases the number of devices used. In addition, in a standing lift, in which the person being assisted stands up in a forward-leaning posture, there is a problem that the person being assisted places the armpits and elbows on the armpits and elbow rests to support the weight of the person leaning forward, which is difficult. Undressing is assisted from behind the caregiver. Also, in a standing lift in which the person being assisted stands up in a backward leaning posture, there is a problem that the person being assisted tends to shift downward.
