Operations in the medical field require a high degree of accuracy and sensitivity else the result could be fatal. Hemodialysis is the process of filtering blood artificially using a dialyzer. It is a process with a high success rate. However, the dangerous two possibilities of blood leakage are the demerit of this system. When such operations are monitored using technology, the danger can be avoided. The blood leak detection system can warn the concerned persons regarding the leak and hence the patient would get immediate attention. Blood leakage due to Venous Needle Dislodgement (VND) and dialysate membrane rupture are detected using image processing technique and optical sensor module respectively, to warn the person regarding the leak. The main unit of the system is a Raspberry Pi 3 B+ board to which the input peripherals like Pi Camera, Analog to Digital Converter from an IR LED Photodiode circuit is interfaced. Periodically, at every time interval, the conditions are recorded and monitored for any change that detects blood leaks. For every detection, the module warns the concerned persons.
