Smart Portable Kidney Dialysis Control And Monitoring System

Hemodialysis is a procedure or therapy which is performed for patients who suffer from kidney or renal failure. This treatment helps to filter water and waste from the human body which in general is performed by the kidneys when they are healthy. Due to the kidney or renal failure a process called dialysis is performed on patients at regular intervals in order to maintain the blood pressure and with the help of hemodialysis the minerals like sodium, potassium and calcium can be balanced. Even though this treatment cannot act as a replacement for kidneys, it can make the patient feel comfortable and better.

The currently available products will detect the blood leakage during the dialysis process only after sensing a leakage of a minimum of 100 ml of blood. Due to this, there are extremely high chances of a disease named ‘Uremia’ to possibly occur in patients. Also the sensing method is basically based on the changes of the voltage signal in the sensor. This device includes a detector having two electrodes spaced apart from each other which is connected to a signal generating source via a lead.

This device also includes a signal processing unit that detects the change of state across the electrodes produced by the introduction of the fluid and an alarm actuated by the change of state. The proposed system is designed in such a way that the blood leakage condition can be detected within 1-2 seconds, which requires a sensing sensitivity of less than 1ml of blood. Photo interrupter is used as a sensor for detecting the blood leakage and it is connected to GSM for the function of wireless transmission of information.
