一种安全型固定输液器的设计

摘要

Objective We designed a safe fixed infusion apparatus to avoid the bottle stopper puncture device slipping out during the emergency transportation both at the hospital and in the war, which could also reduce the incidence of needle puncture. Methods The safe fixed infusion apparatus design included two symmetric L components. The L component included a top hook, a joint, a pushing handle, a fixed baffle and a retaining needle. The retaining needle included a cap and an extension rod. Results After several clinical tests, we found that the top hook of the designed safe fixed infusion apparatus could get stuck in the infusion bottle, which could avoid the bottle stopper puncture device slipping out. The retaining needle could seal the needle tip of the bottle stopper puncture device, reducing the incidence of needle puncture. Conclusion The safe fixed infusion apparatus which is well designed with delicate structure and is easy to use. The design can meet the requirements of intravenous infusion in various sorts of circumstances and is worthy of spreading.%目的 设计一种安全型固定输液器,以避免瓶塞穿刺器在医院临床、战现场救治和转运过程中从输液瓶中滑落并降低针刺伤的发生率.方法 该安全型固定输液器的瓶塞穿刺器固定器包括两个个对称设置的相同的L形组件;L形组件包括顶钩、连接部、推压柄、挡杆固定部和挡针部;挡针部包括挡针帽、延伸杆.结果 经过多次临床测试,该安全型固定输液器的瓶塞穿刺器的顶钩可以卡住输液瓶口,避免了瓶塞穿刺器从输液瓶中滑落,挡针部可充分封堵瓶塞穿刺器的针尖,降低了针刺伤的发生率.结论 该安全型固定输液器,结构精巧合理、使用方便,可满足各种环境下静脉输液的需要,值得推广使用.
