胸腔穿刺是治疗渗出性胸膜炎的一项有效措施,原穿刺针由于多次高压灭菌橡胶管变软,管腔变大,抽液时注射器乳头与扩大的橡胶管内腔存在间隙,必须用左手大拇指及示指捏紧接头,以防空气进入胸腔,抽液十分费劲,且不安全。我们将胸腔穿刺针橡胶管远端嵌上一枚16号输血针座(锯掉针体),用 Thoracentesis is an effective measure for the treatment of exudative pleurisy. Since the original puncture needle softens and the lumen becomes larger due to multiple autoclave rubber tubes, there is a gap between the syringe nipple and the enlarged rubber tube lumen during pumping, and the left hand Thumbs and fingers finger tight joints, to prevent the air into the chest, pumping fluid is very strenuous, and not safe. We will embed a distal thoracic needle rubber tube a blood transfusion needle seat 16 (saw off the needle), with
