“Non-Invasive Hemoglobin measurement device”.

Objectives:

• To develop this device with reasonable accuracy and minimum measurement delay.
• To develop this device at low power supply due to this device could work more efficiently.
• To develop this device with ease to handle, easy to operate and be available for general use

An invasive approach comprises blood sample collection. The samples are centrifuged for separation of serum and prepared samples. The Hb value of the samples are extracted by the Analyzer. In non-invasive approach the sensing part would be fingertip/earlobe or skin between fingers. Hemoglobin in blood consists of various components such as Oxy-hemoglobin, deoxy-hemoglobin, carboxy-hemoglobin and meth-hemoglobin. Using the optical characteristics of these components in blood, total hemoglobin concentration can be determined. The system consists of light detection and signal processing. Based on the data available from light detection and signal processing part Hb can be predicted using regression model.
