  Thirdly, in order to widen the contact surface with the leg as the anti-paddle mat goes from the knee to the leg and then to the foot, it is formed in a trapezoidal shape with the lower side longer than the upper side in side view. Can be prevented more reliably.

  According to the first aspect of the present invention, since the mat that comes into contact with both legs is made of a soft surface material containing a low-resilience cushion that does not feel pain even if the skin is pressed for a long time, the elderly requiring care Can be sandwiched between both legs in a sitting position on a chair, a wheelchair, or a lying position on a bed, to relieve knee compression pain due to hip adduction or prevent pressure ulcers.

  According to the second and third aspects of the present invention, a mat portion including a cushion used by being sandwiched between both legs, and several belts for fixing the mat to an appropriate place on one or both legs so that the mat does not come off. The mat part covers the space from the knee part to the foot part with the knee bent, and the mat part is connected to the leg part as it goes from the knee part to the leg part. In order to widen the contact surface, it is formed in a trapezoidal shape with the lower side longer than the upper side in side view. The cross section of the mat is rectangular and has a large rounded corner so that it can be easily sandwiched between both legs. Furthermore, the mat surface fabric is soft and easy to adhere to the hook-and-loop fastener. Since a male fastener of a hook-and-loop fastener is attached to a part of the outer side of the belt attached to the thigh or crus, it can be attached to and detached from an appropriate position on the mat surface. Therefore, the user can relax without feeling a sense of restraint by the belt, and the assistant can also use the mat to reduce the burden of assistance.
