摘　　要：本文讲述了一种新型的、用于骨科手术的气压式自动止血带的研制。它通过一个气压传感器感知止血带内的压力 ,利用墙壁内的高压氧气接口 ,由单片机来自动控制压力 ,具有定时时间显示和压力显示 ,自动充气和放气等功能。克服了现有止血带操作复杂 ,灵活性差 ,工作繁重等缺点。In this paper,a new model air pressure strap for homeostasis with automation used for orthopaedics operation is introduced.The pressure of the strap is detected with one air pressure sensor.With the high pressure oxygen pipeline in the wall,the air pressure in the strap is controlled by single-chip microprocessor,so the strap has some functions,such as timing,displaying the time and the air pressure,auto-charging and auto-deflation etc.The air pressure strap for homeostasis overcomes those weaknesses of the old model strap,such as complex operation,inconvenience,hard-working etc.
