The seat cushion
In order to avoid pressure sovers, the mat should be highly careful, it is possible to use eggcrate type or Roto pad as far as possible, this pad is composed of a large piece of plastic, there are a large number of papillary plastic hollow columns with a diameter of about 5cm, each column is soft and easy to move, the patient sits after the compression surface into a large number of compression points, and the patient a little move, The pressure point changes with the movement of the nipple, so that the pressure point can be constantly changed to avoid the constant pressure of the same area caused by pressure sores. If not, a layer of foam should be used, the thickness of which should be 10cm, the upper layer of high density polyarethane 0.5cm thick foam, the lower layer of medium density of the same properties of plastic, high density of strong support, medium density of soft comfort. In the sitting position, the ischial nodule pressure is very large, often exceed the normal capillary end pressure 1~16 times, easy to form ischemia pressure sores. In order to avoid excessive pressure here, a piece of the cushion is often dug out at the corresponding place to make the ischial nodule overhead. When digging, the front of the cushion should be 2.5cm in front of the ischial nodule, and the side should be 2.5cm in the lateral of the nodule, with a depth of about 7.5cm. After digging, the cushion is concave and the notch is behind.
