摘要
通过健康受试者的止血压力实验获取受试者上/下肢止血压力与其收缩压、舒张压、肢体周径、体重指数等参数之间的相关性,并根据相关程度建立回归方程。基于C8051F340单片机研制可跟踪收缩压的智能气压式止血装置,并对其的功能及稳定性进行验证,结果表明,该智能气压式止血装置可根据收缩压实时调整止血袖带压力,阻断血流。
The correlation coefficients between arterial occlusion pressure and systolic blood pressure, diastolic blood pressure, limb circumference, body mass etc were obtained through healthy volunteer experiments, in which tourniquet were applied on upper/lower extremities. The prediction equations were derived from the data of experiments by multiple regression analysis. Based on the microprocessor C8051F340, a new pneumatic tourniquet system that can determine tourniquet pressure in synchrony with systolic blood pressure was developed and verified the function and stability of designed system. Results showed that the pneumatic tourniquet which automatically adjusts occlusion pressure in accordance with systolic blood pressure could stop the flow of blood to get a bloodless field.
