The processes involved in measuring the blood components. When the finger is placed over the sensor, the sensor could sense the signal and measurement of blood can be done. Unless results in displaying no detection of blood. When the finger is placed on the sensor, the sensor starts to senses the blood signal. Within seconds the display changes into blood detected and the calculating process begins.
Anemia affects worldwide and is one of the leading public health issues in the developing world. It plays a major role as a confounding factor in the study of maternal and child health as well as in key diseases such as diabetes, HIV, malaria, and malnutrition. For example, 44% of maternal deaths are related to anemia and over 70% of HIV patients are anemic. Anemia has a negative economic effect, estimated by 4-7%of GDP. The key to combating anemia is the diagnosis and monitoring of hemoglobin. However, current hemoglobin (Hb) tests involve invasive blood drawing, with the potential of infection risk to healthcare providers. This hampers the necessary hygienic infrastructure and skilled healthcare providers. Thus, non-invasive hemoglobin screening was declared by the WHO as one of the key medical technologies to improve global health.

Why: Problem statement

Conventional methods are mostly used to calculate blood components. These conventional methods involve pricking of blood with a needle and sending it to the laboratory for further analysis. This results in delay and chances of infection. So we are using a non-invasive method to overcome these problems.

How: Solution description

The proposed work deals with the utilization of the noninvasive technique like pulse Oximetry to design a portable, simple, low cost and easily operatable to determine blood components in real-time. This model is useful for continuous monitoring purpose. Also, for the chemotherapeutic patient with bleeding disorders and anemic patients this system provides the frequent checking of blood components with a quick and safe assessment of results. The availability of a home-use system, as opposed to clinical-use equipment, has greatly improved the quality of life of such individuals. However, such monitors require blood drawn through finger pricks for each test, which causes pain and inconvenience. Each test also requires a new test-strip, contributing to the recurring cost of such a device. A complete model of the various sensors along with the controller is designed and models are used to analyze and detect the blood components. 

How is it different from competition

Normally, in India, we are not using this noninvasive method to calculate the hemoglobin content. In this method, more testing chemicals are used for testing purposes for this area the cost increases for using a chemical solution. So we suggest this method that will be more accurate and it does not harm the skin. 

Who are your customers

This device can be used by all medical practitioners, in hospitals, by anaemic patients etc. 

Project Phases and Schedule

The present invention provides an apparatus and methods which can analyze blood in a Non-invasive manner by imaging with good accuracy blood cells moving in blood vessels in the living body and analyzing the morphology and number of the blood cells. The race for the next generation of reliable and painless glucose monitoring for diabetes patients. As technology advances, both diagnostic techniques and equipment will improve and the main technologies currently being explored for noninvasive monitoring.
