The Wrist Fixer System of Three Position and Nine Indicators Pulse Diagnosis Instrument

The research is to develop a Wrist Fixer System which is used by Three Position and Nine Indicators Pulse Diagnosis Instrument (TPNI Pulse Diagnosis Instrument). The system contains a PC-Based Controller, a Wrist Fixer, an USB I/O card, and two Accelerometers. Chinese doctors practiced the methods for inspection. They practiced listening, smelling, inquiry, and palpation to make diagnoses in Traditional Chinese Medicine (TCM). Actually, Palpation is the best method to know the patient's physiology. TPNI Pulse Diagnosis Instrument is a tool which is used to show and analyze the feeling of the doctor's fingers. The signal is showed by 3D map. And it is helpful for the quantification of pulse diagnosis and its research afterward in TCM. The sampling procedure of TPNI Pulse Diagnosis Instrument is that the Chinese doctor set the location of Cun, Guan, Chi, Fu, Zhong, Chen and get the signal of pulse diagnosis by using the location data. In TCM, Chinese doctor used pulse pillow to fix the patient's wrist. And this research is to design a Wrist Fixer System which can record the angle data of the patient's wrist and reply it when the TPNI Pulse Diagnosis Instrument is sampling the signal. In addition, the correctness can be promoted. The system has been tested and it can record the angle data of the patient's wrist and reply it at the time when TPNI Pulse Diagnosis Instrument gets the signal correctly.
