出器。In circuits through which body fluids flow, there is a body fluid flow tube that has a built-in filter and is integrated with the filter (a part of which is made of a flexible material), and a non-flexible body fluid flow tube that sealsly accommodates the body fluid flow tube. It has an outer tube made of material, and the pressure of the circulating body fluid is detected by the fluid filled in the sealed chamber between the outer wall of the body fluid flow tube and the outer tube without substantially contacting the body fluid with the air. Features: Pressure detector for body fluid processing circuits.
