Abstract:

目前用于清洗腔内手术伤口的冲洗泵本身不带温度控制功能, 都是使用预先加热好的冲洗液。医用恒温冲洗泵系统直接抽取室温的冲洗液, 并冲出固定流量且温度符合手术要求的冲洗液, 实现了流量控制和水温控制两大功能的结合。医用恒温冲洗泵系统主要包括冲洗部分、温度控制部分、液晶显示部分、按键输入部分和异常监测部分。先介绍系统各部分的设计方法和原理, 再说明系统参数的调试方法, 最后根据实验结果讨论了系统的性能。
The flushing pump which is applied to clean operative wound has no temperature controlling function up to now, and doctors have to prepare the flushing fluid that has previously been warmed. The flushing pump system with medical constant temperature designed in our laboratory can absorb flushing fluid at the room temperature, and then eject flushing fluid with the temperature in accordance with the requirements of operations at a controlled constant flow rate. The system combines flow rate control with temperature control functions. The flushing pump system includes flushing part, temperature controlling part, key inputting part, liquid crystal displaying part and exceptional situation monitoring part. The present paper introduces the design method and principle of each part of the system at first, and then gives the debug method of all the system parameters. Finally the paper discusses the performance of the system according to the result of the experiment.
