PROBLEM TO BE SOLVED: To provide a drip chamber for pressure monitoring which, by a diaphragm, can easily transmit a pressure fluctuation in a blood chamber to a pressure gauge through air in an air chamber.SOLUTION: A drip chamber for pressure monitoring includes an upper connection part 2, a lower connection part 3, an intermediate connection part 5, a first connection pipe 7, and a second connection pipe 8. A diaphragm 15 is disposed inside the drip chamber 1. The diaphragm 15 includes a deformation part 16 and a fixation part 17, and divides the inner space of the drip chamber 1 into an air chamber SPA and a blood chamber SPB through the deformation part 16. The fixation part 17 has a roughly dome-shaped deformation part 16 projected toward an upper part U side, or a roughly sheet-like deformation part 16 formed inside. The deformation part 16 is formed of a material having gas permeability which elastically deforms by a pressure fluctuation in the blood chamber SPB, and can transmit the pressure fluctuation in the blood chamber SPB to a pressure gauge through air in the air chamber SPA.SELECTED DRAWING: Figure 2 |
