Coagulation is an intricate process due to which blood clot formation takes place.It is an intrinsic part of hemostasis thrombus blocks the blood vessels, and as a result, bleeding will stop.During cardiopulmonary bypass surgery, the hemostasis status of a patient is mandatory to monitor continually to shun uncontrolled bleeding or coagulum disorders.Increasing safety for patients undergoing surgical procedures is the primary objective of coagulation monitoring of hemostasis.Coagulation and bleeding abnormalities are among the crucial causes of death in the developed world, so research in this area is necessary.Now for the monitoring of hemostasis status during cardiopulmonary bypass, there is a solution through this proposed model for coagulation monitoring.In ongoing coagulation monitoring by mechanical principle, the clotting time (i.e.PT and aPTT) is mandatory to diagnose the bleeding disorder.The coagulation monitoring device is an automated laboratory instrument based on mechanical principles, used to measure the coagulation time.The prototype requires samples that have been drawn in the cuvette.The system has a stable temperature (i.e.37˚C) through a temperature sensor, DC fan, and heating coil controlled by a microcontroller through the relay.It is equipped with a DC motor and magnetic ball due to which the blood coagulation is monitored by the rotation of the magnetic ball in the cuvette.The rotation of a magnetic ball is sensed by a sensor (i.e.Hall Effect sensor module), by cause of this, the timer will start, as the viscosity of blood increases the magnetic ball faces the hindrance in rotation and the formation of fibrin take place, as a result, the timer will stop.This device is programmed so that the formation of blood clots is befallen.
