Determination of Blood Constituents Using Laser Based Systems

Authors : V. Ashok and K.S. Tamilselvan

Abstract: Diseases can be diagnosed from the blood flow through blood constituents which are oriented in the direction of blood flow. In conventional methods, skin texture is pricked for the collection of blood samples which is known as invasive technique. It may lead to damages in the skin texture and intrusion of foreign particles in our body, wastage of blood, painfulness and discomfort to the patients. It requires the assistance of skilled persons to carry out the process of determination. To overcome these problems, non-invasive technique is employed. One of the non-invasive techniques used here is laser based system. In the present study, the laser beam is guided to the index finger as a source of target. The scattered laser beams are collected by the fibre optics which is circumferentially arranged along with transmission fibre to the photo detector. The scattered light is converted into its corresponding electrical voltages. The collected signals are correlated with the blood constituents collected invasively at the time of signal acquisition. The data collection analysis and further processing are done by using Cortex-M4 processer and MATLAB. Simulation results demonstrate that blood constituents in the blood flow with respect to the acquired signals are significantly closer to the calculated value.
