- 摘要：
PROBLEM TO BE SOLVED: To provide a pressure detector capable of precisely detecting the pressure in a blood circuit.
SOLUTION: In the pressure detector 1 equipped with the chamber member 2 connected to the blood circuit for subjecting blood to extracorporeal circulation and capable of being deformed by accompanying the pressure change in the blood circuit and the detection means (a first arm 3 and a second arm 4) brought into contact with the chamber member 2 and capable of detecting the force caused by the deformation of the chamber member 2 and capable of detecting the pressure in the blood circuit on the basis of the force detected by the detection means, the chamber member 2 is formed of a soft resin 2a and has a hard resin part 2b comprising a hard resin harder than the soft resin and the detection means is brought into contact with the hard resin part 2b to detect the deformation force of the chamber member 2 to thereby detect the pressure in the blood circuit.
