BLOOD REMOVAL PRESSURE MEASURING SYSTEM AND METHOD

摘要

PROBLEM TO BE SOLVED: To provide a blood removal pressure measuring system and a method capable of quickly and precisely measuring a blood removing pressure of the primary side of a blood pump using a pressure detecting value from an existing pressure detector without changing an existing blood circuit and without adding a pressure detector to a blood dialyzer. SOLUTION: The system is the blood removal pressure measuring system in a blood extracorporeal circulation device having the blood circuit for circulating the blood between the inside of the body of a patient and the same using a blood pump and has a pressure detecting means detecting the pressure in the blood circuit in the downstream of the blood pump, and a blood removal pressure calculating means calculating a blood removal pressure from the amplitude of the fluctuation of the detected pressure by the pressure detecting means and a set flow rate of the blood pump.
