摘　　要：本文设计和实现了用于四肢手术和急救的气压式自适应止血带装置。设计以单片机C8051F340和血压测量模块CSN602核心的气压式自适应止血电路,编写了自适应止血装置的相关程序并开展了验证系统功能及其稳定性的实验。结果表明,气压式自动止血带实现了收缩压等参数的准确测量,可根据收缩压、肢体周径等参数对止血袖带进行充、放气调整。本文研制的气压式自适应止血装置经系统集成和优化完善,可用于肢端手术的止血环节,达到术野清晰的效果。A new adaptive pneumatic tourniquet was developed for limb operation and first-aid. The crucial hardware circuits of the adaptive pneumatic tourniquet were designed based on the microprocessor C8051F340 and blood pres- sure module CSN602, software was programmed and an experiment was carried out for verifying the system. Results showed that the prototype could measure accurately systolic blood pressure, heart rate and other relative parameters and the designed device could adjust tourniquet cuff＇s pressure through inflation and deflation according to systolic blood pressure and limb circumference. This designed system integrated the advantages of the adaptive pneumatic tourniquet, and could be used for controlling life-threatening extremity hemorrhage operation and maintaining a bloodless opeation field.
