PROBLEM TO BE SOLVED: To provide a squeeze type pump capable of detecting closing of a liquid flow passage without newly connecting a separate member to the liquid flow passage.SOLUTION: A squeeze type pump includes: an installation recessed part 8a capable of being installed with a squeezed tube 1a connected to an artery side blood circuit 1; and rollers 10 capable of fluidizing internal liquid in the artery side blood circuit 1 by squeezing the squeezed tube 1a installed to the installation recessed part 8a in the long direction while compressing the squeezed tube 1a in the radial direction. The squeeze type pump includes: a load sensor 18 capable of detecting displacement in the radial direction of the squeezed tube 1a installed to the installation recessed part 8a; and closing detection means 19 capable of detecting closing of the artery side blood circuit 1 on the basis of the displacement detected in the load sensor 18. |
