Description

technical field

[0001] The invention belongs to the field of power components, and in particular relates to a peristaltic pump. Background technique

[0002] Peristaltic pumps pump fluid by alternately squeezing and releasing the pump tubing. It's like squeezing a fluid-filled hose with your fingers, and the fluid in the tube moves forward as the fingers slide forward. The peristaltic pump is also based on the same principle except that the fingers are replaced by rollers. Peristaltic pumps are often used for the transportation of high-viscosity liquids, which have the advantage of accurate measurement. Because the liquid flowing in the conduit does not contact the pump body, does not generate pollution, and the flow rate is adjustable, it is suitable for use in blood collection and transfusion equipment to provide power for blood collection and retransfusion.
