This is different from the actual use environment of the infusion pump. In the clinical application of the infusion pump, the output end of the infusion set pipeline is the human vein, so the pressure value at the output end is the human venous pressure. The pressure value at the output end of the quality control (calibration) process of the infusion pump is inconsistent with the human venous pressure, resulting in inaccurate simulation data.

[0026] The present invention will be further explained below in conjunction with specific implementation methods.

[0027] like Figure 1-5 As shown, the present embodiment provides an output end pressure simulation device for quality control of an infusion pump, comprising a water tank 1 and a partition plate 2 fixed inside the water tank 1, wherein the front and rear sides and the bottom of the partition plate 2 are fixedly connected to the inner wall of the water tank 1, and the height of the partition plate 2 is lower than the height of the water tank 1, and the partition plate 2 divides the water tank 1 into a liquid collection area 1 101 and a liquid collection area 2 102.

[0028] A side wall of the partition plate 2 close to the liquid collecting area 101 is fixedly connected to a limiting strip 3 , and a clamping opening 103 is formed between the limiting strip 3 and the inner wall of the liquid collecting area 101 .

[0029] The front side wall of the water tank 1 is provided with a scale 7, which is arranged close to the limit bar 3. The depth of the lower end of the hose at this time can be seen through the scale 7, and the pressure value at the output end of the hose at this time can be directly calculated through P=ρgh.

[0030] During the experiment, one end of the infusion tube is connected to the infusion bag, and then the other end of the infusion tube is fixedly connected to the infusion pump, and the output end of the infusion pump is connected to the infusion equipment analyzer; then one end of the hose is connected to the output end of the analyzer, and the other end is connected to the clamping port 103 of the device. The hose is clamped in the clamping port 103 to achieve limit and adjust to a suitable position. Fill the liquid collection area 101 with distilled water, that is, adjust the pressure value at the output end of the hose at this time.

[0031] The depth of the lower end of the hose can be seen from the scale 7, and the pressure value at the output end of the hose can be directly calculated using the pressure calculation formula P=ρgh. The infusion pump and analyzer are started. At this time, the liquid level in the liquid collecting area 101 remains unchanged, and the overflowed liquid enters the liquid collecting area 2 102 through the top of the partition plate 2. During the experiment, the water pressure value at the output end of the hose remains constant.

[0032] It simulates the human venous environment well and is more in line with reality.

[0035] In addition, in order to facilitate further fixation of the hose, an I-shaped plate 4 is detachably installed on the inner wall of the water tank 1. The I-shaped plate 4 is located above the partition plate 2, and an elastic band 5 is fixedly connected to the surface of the partition plate 2.

[0036] The hose can be passed through between the surface of the I-shaped plate 4 and the elastic band 5, and the elastic band 5 is loosened. Under the action of elastic force, the elastic band 5 presses the hose tightly to achieve fixation.

[0038] A pull pin 6 is fixedly connected to the top of the I-shaped plate 4 , and the I-shaped plate 4 can be conveniently removed from the I-shaped groove 104 by pulling the pull pin 6 upward.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit it.
