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 |
