ABSTRACT:
Haemodialysis is a method for removal of impurities such as creatinine, phosphorous and potassium and urea, as well as free water from the blood when kidney failure. If the patient has kidney malfunctions the impurities are removed by using artificial means of a machine called haemodialysis. The procedure of dialysis is highly tedious and time consuming to the patients. The patients have to visit hospital frequently 1 to 4 times per week depending on the condition of their kidneys. The blood from the patient is removed from radial artery then sent to the dialyser for filtering. The filtered blood is sent back into the body through femoral artery. The dialysing procedure has its own risks and limitations such as fatigue, anaemia, formation of embolus and risk of infections. These drawbacks can be overcome by using a wearable kidney dialyser (WKD) which is a miniature form of dialyser machine. This can be worn as a belt hanging around the patient’s waist. The wearable kidney dialyser contains pump system that draws blood in and out of the body, a dialysing unit, temperature monitor, pH meter, flow sensor, battery and a solar panel for extra power supply. The wearable artificial kidney is driven using batteries and solar panel for power generation. The wearable kidney dialyser can be worn continuously that will perform the function of natural kidney. The rate of filtration is 12ml/min in a synchronous manner. The advantage of the proposed method is slow and continuous process which may avoid fatigue and other complications. The patient no need of wasting their valuable time they can move around even during the dialysing procedure. Mobile application is developed to monitor all clinical parameters of the patient using android app to communicate the physician at remote distance.
