Preliminary Research of an Optical Sensor for Measurements of the Blood Chamber Volume in the POLVAD Prosthesis

Abstract

The article presents preliminary research of an optical system for using in the temporary blood volume measurements in the Polish Ventricular Assist Device (POLVAD). The basis for the proposed solution is the measurement of the light reected from the membrane in dierent congurations of light emitters and light detectors. The paper is describing a proposed measurement technique, measurement circuit and preliminary static measurements results of the developed measurement system. Future development plans are stated.
