Microcontroller Based Clotting Time Meter

Abstract

This project presents a system that can be used to measure the clotting time of blood, the system depends on the light absorbance technique. The light passes through a sample of blood using photo source then taken the light absorption of the light using photo detector to measure the clotting for this sample of blood. In our project the microcontroller will be used to process the data coming from light detecting circuit and store the data in EPROM memory. The clotting time of the blood is very important for laboratory technicians, doctor, and hospital. Blood coagulation is very important to human life since it stops and limits the Blood cut drain. Respect of the project measuring time clot blood plasma components, has found through experience that the time for plasma coagulation ranging between 9-16 second person and varies depending on age and also the method used to measure time coagulation Without blood coagulation, many of the body s important biological functions will not be able to proceed. For instance, some platelet disorders make people more prone to hemorraghing; such persons may be candidates for bone marrow transplants, or for constant reception of clotting factors. If you have a platelet disorder, you may be banned from playing strenuous sports or engaging in dangerous activities that will put you at greater risk for injury and bleeding
