中医传感针及配套多通道测量仪的研制

研制的中医传感针及其配套多通道测量仪用于实时、在体、同时测量中医经络上多个穴位点的温度、氧分压及pH值。测量的数据可有选择性地显示或送到上位PC机处理、存储。给出了该传感针的设计原理、测量仪的硬件结构及典型的测量方法和结果。测试结果表明:留针后穴位的温度基本上不随时间变化,而氧分压和pH值则在一定时间内会随着时间的增加而改变,最后,趋于稳定。

Development of needle sensor for Chinese medicine and related multi-channel measuring instrument

The needle sensor and related multi-channel measuring instrument are used to survey in vivo the temperature,partial pressure of oxygen and pH of different acu-points in the body simultaneously.The result can be displayed or sent to PC for processing and save.The design principle of the sensor,the hardware structure and measuring method are introduced.The typical measuring results are also given.The application shows that the temperature of acu-points is almost the same after acupuncture while the partial pressure of oxygen and pH change first and go to steady after a definite time.
