Diagnosing Diseases through pulse using pressure sensor

Diagnosing Diseases through pulse - “finding any disease using nadi” is an automated system to find the diseases and its related informations about the human body. This project provides detailed information and reports on patients by obtaining their nadi as a time series. The nadi pulses are sensed by the fingertip, which actually measure the pressure exerted by the artery. These pulsations are very minute in pressure units and a set of three such pressure transducers is mounted on the wrist to sense three location pulses, namely vata, pitta and kapha. The electrical signal proportional to the pressure experienced, in differential mode, by the pressure sensing element is then digitized using the 16-bit multifunction data acquisition card NI USB-6210 (National Instruments, TX, USA), having an interface with the personal computer. The data is captured at a sampling rate of 500 Hz (which is sufficiently higher than the Nyquist criteria) for a predetermined length of time. Our application shows the probable disease results according to the pulse waveform and pressure applied at the sensing element per unit time. Hence our Indian Medicine Practitioners can use this system as automated computer-aided diagnostic tool.
