[0008] In the above technical scheme, the upper part of the mounting frame is provided with a pump core accommodation groove.

[0009] In order to achieve the above purpose, the second technical scheme of the utility model is as follows: a small peristaltic pump, having a shell, a pump core is arranged in the shell, the lower part of the shell is provided with a pipe connecting port, and the cross type pipe joint is clamped at the pipe connecting port.

[0010] In the above technical scheme, the shell is provided with a limiting protrusion, the two sides of the mounting frame are provided with limiting clamping grooves, and the mounting frame is clamped on the limiting protrusion through the limiting clamping grooves.

[0011] In the above technical solution, the limiting protrusion and the limiting clamping groove on one side are arc-shaped, and the limiting protrusion and the limiting clamping groove on the other side are conical.

[0012] In the above technical solution, the bottom of the mounting frame is arc-shaped.

[0013] In summary, the technical solution of the present application has the beneficial effects of the traditional technical means: the present application adopts a cross-type pipe joint on the peristaltic pump, and the catheter can be directly connected to the pipe joint without being straightened after winding the pump core once, which can effectively increase the pressure path of the catheter, the extrusion stroke of the guide roller is larger, the impact force received by the liquid inside is smaller, and the mounting frame can be taken out from the shell, and after being installed, it can be installed into the shell, which is more convenient to install.
