当前国内外所用的止血带过窄,止血方式仍是环绕加压的情况始终没有突破,因此无法摆脱旧止血带的弊端。我们根据生物力学原理在实验研究的基础上,研制了 PT—1型局部充气止血带,获得良好效果。PT—1型止血带用的确良缝制,长75cm、宽13cm,内装一个16×13(cm)的橡胶气囊,气囊上设有一根胶管供充气或放气以及测定囊内压用。每套 PT—1型止血带备有一充气橡 At present, the tourniquet used at home and abroad is too narrow, and the way of stopping bleeding is still no breakthrough around the pressurization, so it can not get rid of the disadvantages of the old tourniquet. According to the principle of biomechanics, we developed PT-1 partial inflation tourniquet on the basis of experimental research and achieved good results. The PT-1 type tourniquet is made of a precision 75 cm long and 13 cm wide with a 16 × 13 (cm) rubber bladder with a hose for inflating or deflating and for measuring intracapsular pressure. Each PT-1 tourniquet is equipped with an inflatable rubber
