1. A wearable Continuous Renal Replacement Therapy (CRRT) device comprising:
- a dialyzer;
a blood circuit configured to move blood from a patient through said dialyzer and back to said patient;
a dialysate circuit configured to circulate dialysate through said dialyzer and to refresh said dialysate;
a microcontroller configured to control the movement of blood and dialysate through said blood circuit and said dialysate circuit respectfully;
a dual-channel pulsatile pump, controlled by the microcontroller, the dual-channel pulsatile pump comprising a single motor, a first pump channel in the blood circuit and a second pump channel in the dialysate circuit, the dual-channel pulsatile pump adapted to be powered by a battery;
a covering substantially covering said wearable CRRT device;
means for enabling a patient to wear said wearable CRRT device attached to said covering;
a moisture sensor, inside said covering for sensing moisture, said moisture sensor providing a moisture signal that indicates moisture presence on the inside the covering, to said microcontroller.

Abstract
A continuous renal replacement therapy (CRRT) device adapted to be worn on a portion of the body of a patient. The CRRT device is worn by the patient and operates on rechargeable batteries for more than 5 hours. Dialysate is used to remove impurities from the blood. The dialysate is recycled and refreshed by a filter section. Less than one liter of dialysate is required to circulate through the wearable CRRT device.
