摘要 自体血液回收机是近年来广泛应用于外科手术的先进仪器。液体滚压泵是自体血液回收机中的关键部件,而其中的滚压轴与泵槽间隙则是关系到血液回收质量等级的重要参数。本文以Flexiforce薄膜压力传感器为感测元件,设计了以STC12C5A60S2单片机为处理核心的滚压泵微量泵距参数自动监测仪器,并具有液晶显示、超限报警等功能。该仪器体积小、易携带、使用方便,完全适用于自体血液回收机的临床应用。 Autologous blood recoverer is widely used in surgical operation in recent years. Roller pump is a crucial component of the equipment, and the slot width between rolling axle and pump trough is an important parameter relative to receiving blood quality. In this paper, the automatic monitoring device of rolling and microgap whose processing core was STC12C5A60S2 chip microcomputer was designed by using Flexiforce thin film force transducer as sensing element. In addition, LCD display and alarming functions were provided. With the advantages of small, portable, convenient usage and so on, the instrument is completely suitable for autologous blood recoverer in clinical application process.
