摘　　要：目的:本文介绍一种智能化测量人体体表受压强度测量仪的研制方法。方法:通过压力传感器作为体表受外施(如弹力绷带、包扎材料等)压力的测试探头;传感器的输出电压信号放大后送入微控制处理器进行处理,即A/D变换,其变换过程全部由软件(C语言的程序代码)完成;结果用数码管(LED)定量显示。结果和结论:该测量仪在测量和调节压力时即时显示压力强度,如kgf/cm2、mmHg、kPa等压力强度值,数据准确可靠,操作简便。Objective： To explore the method of measuring the intensity of pressure on dermal scars. Methods： The testing in- ductor to taste intensity of pressure （being forced by such as elastic bandages, enswathements ,etc.） was by way of the pressing transducer. The pressure signal （degree mv） of the transducer was magnified and transferred to tiny controls where A/D switch happened. All of processions were accomplished by soft wares of C language and results were displayed by LED. Results and Conclusions： The apparatus can measure the intensity of pressure basing on different intensities （such as kgf/cm2 or mmHg or kPa, etc）.The results were credible and the operations were simple.
