临床上各种原因所致的急性大出血,可导致病人休克,此时急需快速补充血液,尽早提高病人循环血量以挽救病人生命。加压快速输血是临床上常用的重要方法。目前,国内各医院所用的加压输血三通管,是通过三通管上的手动开关来对血液流向进行控制的。医务人员每抽一(注射器)管血,就需扭动开关一次,每推一管血也需扭动开关一次,抢救一个中度失血病人,就需来回扭动开关上百次,动作复杂,操作麻烦,增加了医务人员的劳动强度。且因长期扭动,开关很快松动,造成血液从开关处外溢,极
Acute clinical bleeding caused by various reasons, can lead to patients with shock, urgent need to quickly add blood, as soon as possible to improve the patient’s circulating blood to save the lives of patients. Pressure fast blood transfusion is an important method commonly used clinically. At present, the hospitals in China use pressurized blood transfusion, which controls the blood flow through the manual switch on the tee. Medical staff pumping a (syringe) tube blood, you need to twist the switch once each push a tube of blood also need to twist the switch once to rescue a moderate blood loss patients, you need to twist the switch back and forth hundreds of times, complex movements, Operation is cumbersome, increasing the labor intensity of medical staff. And because of long-term twist, the switch quickly loose, causing the blood spill from the switch, very
