一、封管液的正确配置
1. Correct disposition of sealing fluid
生理盐水 150 ml 加入肝素钠 12 500 U
Addition of 150 ml normal saline to heparin sodium 12 500 U
二、封管的方法
2. Sealing methods
1、输液完毕后均吸取生理盐水 150 ml 加入肝素钠 12 500 U (2 mg)肝素液 3 ml ,用 5 ml 注 射器将针头全部插入肝素帽内,均匀注入肝素液,剩余 1.5ml 后边退针边注入封管液,肝素帽 内不留空隙，以达到管内充分肝素化。
1. After the infusion, 150 ml of normal saline was absorbed and 3 ml of heparin sodium 12 500 U (2 mg) was added. All needles were inserted into the heparin cap with 5 ml syringe, and the heparin solution was injected evenly. The remaining 1.5 ml was withdrawn from the needle and injected into the sealing fluid. No space was left in the heparin cap to achieve full heparinization in the tube.
2、输入高浓度或刺激性药物后封管时先静脉滴注或推注生理盐水 20ml 后， 用生理盐水 150 ml 加入肝素钠 12 500 U (2 mg)肝素液 3 ml 缓慢正压封管。
2. Intravenous drip or injection of saline 20 ml before sealing the tube with high concentration or irritant drugs, then add 150 ml saline 12 500 U (2 mg) heparin solution 3 ml to slow positive pressure sealing the tube with heparin sodium 12 500 U (2 mg).
