Description

[0001]
BACKGROUND OF THE INVENTION
The present invention relates to a knee joint supporter used for knee joint disorders.
[0002]
[Prior art]
There are various types of knee joint supporters used for the treatment and prevention of knee joint disorders, one of which is a sleeve type having a main body formed of a sleeve-like stretch material, that is, a tubular elastic material, One is a rectangular body with a stretchable material wrapped around the knee joint, and the front and back of the knee can be opened to the left and right with respect to the axial direction. Another type is a semi-open type in which either the thigh or the lower leg is closed, and the other is openable at the front or back of the knee and joined with a hook-and-loop fastener as an open type deformation. The sleeve-type knee joint supporter must bend the knee and pass the ankle through the body, pulling the body up to the appropriate position of the knee joint, but this operation is difficult for patients with knee joint flexion difficulty or grip strength It is very difficult for children and the elderly. Open type and semi-open type knee joint supporters are easier to wear than sleeve types, but the left and right ends of the open part are overlapped with the other, so the left and right ends are pulled in the circumferential direction. There is a problem that the force tends to be uneven and the supporter rotates with respect to the direction in which the tensile force is strong, thereby impairing the fit.
