Abstract

A Continuous and real time health observing has become an important subject of our life. A simple and feasible Portable devices has done a major role, especially in the biomedical field. We have implemented and developed with an experimental study for two pulsation tubes simultaneously as a fetal and maternal abdominal vessel based on optical continuous detection. A wide range of frequencies from near-infrared to red light wavelength were generated through a phantom. The reflected signals were acquired from one silicon diode and separated by a demodulator through a USB connection to PC by using an NI DAQ 6351 and analysed using LABVIEW software. The settled simulated vascular system contains from a two independent adjustable tube system, demonstrating the fetal and maternal vessel system in different frequencies simultaneously. The two arterial hearts beat pressure with different frequencies is generated utilizing a two different pre-pressure controllable piston pumps with two handmade automatic adjustable relief valve and two flexible tubes to create a complete artificial model of the fetal and maternal vessel system of a dynamic adjustable beat per minute (B.P.M.). The major achieved results are the reflected RED and IR PPG signals from both top and bottom tube simultaneously from one silicon diode. The system that has designed is convenient with any detection systems for a transabdominal optical PPG system tests before produced to the clinics.
