[0015] It is worth noting that the housing is also equipped with a switch and a touch screen. The switch turns the entire unit on and off, and the touch screen allows staff to directly issue work commands to control the motor to drive the rotating wheel.

[0016] It is worth noting that there are a total of 36 rotors, and the 36 rotors are evenly distributed on the side wall of the wheel.

[0017] This utility model has the following advantages:

[0018] 1. This utility model sets a rotating wheel on the housing and sets several rotors around the rotating wheel that rotate with the rotating wheel. By using multiple rotors, the flow rate of liquid in the pipeline can be accurately controlled, thereby improving the flow accuracy, controlling the volume of the injection liquid, and improving the quality of use of the injection pump.

[0025] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present invention.

[0026] This utility model provides a medical infusion pump, which works by setting a rotating wheel on the housing and setting several rotors around the rotating wheel that rotate with the rotating wheel. The multiple rotors are used to achieve precise control of the liquid flow rate in the pipeline, thereby improving the flow accuracy, controlling the volume of the infusion liquid, and improving the quality of use of the infusion pump.

[0027] The present invention will be further described in detail below with reference to embodiments and specific implementation methods.

[0028] like Figure 1 and Figure 2 As shown, a medical infusion pump includes a housing 1 and a pump assembly disposed on the housing;

[0029] The pump assembly includes a circular placement groove 2 on the surface of the housing, a rotating wheel 3 on the circular placement groove, 36 rotors 4 on the rotating wheel, a first placement groove 5 on the housing, a second placement groove 6 on the housing, and a pipeline 7 in the circular placement groove.

[0030] The rotors are mounted on the outer side wall of the rotating wheel and rotate with the rotating wheel; and 36 rotors are evenly distributed on the side wall of the rotating wheel.

[0031] Both the first and second placement slots are tangent to the edge of the circular placement slot, and are arranged perpendicularly to each other. The first placement slot has an inlet 8, and the second placement slot has an outlet 9. The inlet and outlet are respectively connected to the pipeline. A pressure sensor 10 is also installed at the end of the pipeline, and the pressure sensor and the outlet are located at the same end of the pipeline.

[0033] The housing is also equipped with a switch 11 and a touch screen 12. The switch enables the entire system to be turned on and off, and the touch screen allows the operator to directly issue work instructions to control the motor to drive the rotating wheel to work.

[0034] In actual use, staff select instructions via touchscreen 12 and then activate the motor via control terminal 9 (such as a computer or other device). The motor drives the rotating wheel 3 to rotate, which in turn drives the rotor 4 to rotate sequentially. As the rotors rotate, the liquid in the tubing is continuously discharged. Due to the large number of rotors, the transmission precision of the liquid in the tubing can be achieved. For some joint surgeries, spinal surgeries, and other small cavity surgeries, higher precision allows for better control of the volume of infusion fluid, thereby reducing patient pain.

[0035] Through the above methods, the medical infusion pump provided by this utility model, by setting a rotating wheel on the housing and setting several rotors around the rotating wheel and rotating with the rotating wheel, uses multiple rotors to achieve precise control of the liquid flow rate in the pipeline, thereby improving the flow accuracy, controlling the volume of the infusion liquid, and improving the quality of use of the infusion pump.

[0036] The above description is only a preferred embodiment of a medical infusion pump disclosed in this utility model.
