Portable smart non-invasive hemoglobin measurement system

Abstract

Analysis of blood substances such as hemoglobin, glucose, protein, cholesterol, etc. are important parameters for health condition monitoring. Traditionally, blood sample is taken using a needle. Some chemical process such as enzyme reaction is required before the final value for concentration is read. Reagents involved in such processes are expensive for both the hospital and patient. Non-invasive measurement is much more attractive by its evident advantages such as real time monitoring and infection free operation. The Hemoglobin (Hb) in human blood is measured and analyzed using Advanced RISC (Reduced Instruction Set Computing) machine processor non-invasively. This investigation helps in ruling out the diseases like anemia (a low hemoglobin level) and polycythemia vera (a high hemoglobin level). At present, the procedures used to measure the Hb concentration in blood are invasive. For this purpose blood is taken and analyzed. The hindrance of this method is the delay between the blood collection and its analysis. The portable smart non-invasive measurement system, discussed in this paper, gives a detailed idea about the hemoglobin concentration in the blood.
