BLOOD PLASMA EXCHANGE DEVICE

PURPOSE:To constitute the device so that it is effective as a blood plasma exchange device, and it can used separately as a blood plasma extracting device and a fluid therapy device, respectively. CONSTITUTION:This device is a blood plasma exchange device for controlling a blood plasma exchanging circuit having a blood extracting circuit for extracting blood from a patient, a blood plasma separating means for separating the extracted blood into a blood plasma component and a blood corpuscle component, a blood plasma extracting vessel for extracting the blood plasma component, a blood corpuscle component returning circuit for returning the blood corpuscle component to the patient, and a purified blood plasma therapeutically injecting circuit for injecting therapeutically the purified blood plasma to the patient. This blood plasma exchange device 1 is provided with a blood plasma extracting device part 2 for controlling the blood extracting circuit, and antiwagulant adding circuit, a blood separating operation by the blood plasma separating means and a blood corpuscle component returning circuit, and a blood plasma therapeutically injecting device part 3 for controlling the purified blood plasma theraoeutically injecting circuit. The blood plasma extracting device part 2 and the blood plasma therapeutically injecting device part 3 are connected so as to be detachable by a communication cable 4.
