Description

A kind of leg disease patient rises and sits servicing unit

Technical field

Risen the present invention relates to a kind of leg disease patient and sit servicing unit.

Background technology

Some old men or leg disease patient because its leg muscle and joint can not be coordinated well, rise sit when With regard to relatively difficult, it is necessary to just can be with by external force, be supported generally by both hands or dragged fixture with pulling and stood up, led to When crossing both hands support, body-support to erectility can not be dragged when fixture is stood up, it is necessary to which surrounding has properly by pulling Fixture and also have certain requirement to the hand strength of patient.

Now there is auxiliary in the art to stand up seat, but the auxiliary is stood up, seat can only allow patient to rise on the seat Sit, and seat volume itself is larger, it is complicated, it is not portable, it is larger using limitation.Also exist in the prior art and stand up Servicing unit, can be by the device with the thing to sit on of other family expenses, such as sofa, chair etc., but the uprisal-assist exists When auxiliary leg disease patient stands up, a larger thrust backward is easily caused to thing to sit on, the uprisal-assist lacks necessity Protector prevent that thing to sit on is mobile and causes leg disease patient to fall down.
