Abstract

The invention discloses a peristaltic pump. The peristaltic pump comprises a pump head and a pump chamber; a cavity for containing the pump head is arranged in the pump chamber; the pump head comprises a pump head support, a roller support, a roller assembly, roller support compression adjustment springs and a roller support compression adjustment screw; the first end of the roller support is rotationally connected with the pump head support, and the second end of the roller support is connected with the pump head support through the roller support compression adjustment screw; the roller assembly is arranged on the roller support; the roller support compression adjustment springs are arranged between the pump head support and the roller support, one end of each roller support compression adjustment spring abuts against the pump head support, and the other end of each roller support compression adjustment spring abuts against the second end of the roller support; and the number of the roller support compression adjustment springs is at least two.

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. [0003] In the prior art, for example, the utility model patent with domestic application number 012057509 discl...
