Hemodialysis is a life-preserving treatment for a number of patients with kidney failure. Hemodialysis is usually done three times per week for about four hours at a time. During the hemodialysis procedure, the patient usually suffering from many inconvenient, fatigue, stress and disturbance in the work of the heart and cardiovascular system are the most common signs. This paper provides a solution to reduce the previous problems by designing a wearable artificial kidney (WAK) taking in consideration minimization the size of the dialysis machine. The WAK system consists of two circuits: blood circuit and dialysate circuit. The blood from the patient is filtered in the dialyzer before returning back to the patient. Several parameters using an advanced microcontroller and array of sensors are considered. WAK equipped with visible and audible alarm system to aware the patients if there is any problem.
