Technical Field
[0001] The utility model relates to the technical field of calibration brackets, in particular to a bracket device used for calibrating medical injection pumps and infusion pumps. Background Art
[0002] Calibration of an infusion pump is a professional and important process to ensure its accuracy and safety in clinical use. During the calibration process, professional testing equipment, such as an infusion pump analyzer, is required to measure and adjust the flow rate of the infusion pump. If the flow rate exceeds the allowable error range, calibration is required according to specific steps to ensure the accuracy of the flow rate. Set the infusion pump to calibration mode (the calibration mode is generally a rate of 50ml / hour, with a preset volume of 10ml). Connect the infusion tube to the graduated cylinder. After the calibration is completed, observe the liquid volume in the graduated cylinder and input the observed liquid volume into the infusion pump system to complete the calibration.
[0003] Existing calibration devices are generally calibrated directly on the infusion stand and can only calibrate one infusion pump, which is inconvenient to operate. At the same time, there is no clamping mechanism for the infusion pump. Fixing the pump can ensure that the position of the pump does not change during the calibration process, thereby improving the accuracy and stability of the measurement.
[0004] In addition, the existing calibration device does not have a structure for placing the measuring cylinder, and the measuring cylinder needs to be placed on the chair separately, which is inconvenient and easy to accidentally touch the measuring cylinder, causing the liquid in the measuring cylinder to leak.
[0005] After searching, the publication number CN220158900U is a frame device for calibrating medical syringe pumps and infusion pumps, which includes a base, a column, a guide rail, a first lifting platform, a first lifting drive mechanism, a second lifting platform, a second lifting drive mechanism, a water tank, and a recovery tank. The utility model simulates the liquid medicine by adding distilled water to the water tank. The first lifting drive mechanism can drive the water tank to move up and down along the column, making it convenient to add water and lift it to the top of the column; the second lifting platform is used to place the standard instrument and the syringe pump or infusion pump to be calibrated. The second lifting drive mechanism can drive the second lifting platform to move up and down along the column, making it convenient to adjust the second lifting platform to the appropriate height according to the interface height of the syringe pump or infusion pump to be calibrated, so as to accommodate the docking of different models of syringe pumps or infusion pumps with the standard instrument and infusion tube.
[0006] The above-mentioned prior art can adjust the height of the water tank, and the lifting platform can adjust the height of the infusion pump, but does not have a fixing structure for the infusion pump. Utility Model Content

At least one infusion pump limiting assembly 6 is provided on the upper side of the table top of the operating table 1. The infusion pump limiting assembly 6 includes a U-shaped rod 61, and clamping plates 62 are respectively provided on both sides of the middle of the U-shaped rod 61. A slider 67 is provided in the clamping plate 62, and the slider 67 matches the clamping plate 62. The slider 67 is fixedly connected to the connecting rod 64, and the connecting rod 64 is fixedly connected to the slide groove 63.
[0031] The middle part of the U-shaped rod 61 is fixedly connected to the straight groove rod 65, and a moving block 69 is provided in the straight groove rod 65. The two ends of the straight groove rod 65 are rotatably connected to the screw rod 68, and the screw rod 68 is threadedly connected to the moving block 69.

[0032] In this embodiment, the rotation of the screw 68 can drive the moving block 69 to move vertically in the straight groove rod 65. The vertical movement of the straight groove rod 65 can drive the connecting rod 66 connected to it to swing. The connecting rod 66 can drive the slider 67 to slide in the slide groove 63. The slider 67 can drive the connecting rod 64 and the clamping plate 62 to move. The clamping plates 62 can move closer to each other or away from each other. When the clamping plates 62 approach each other, a clamping effect is achieved. When the clamping plates 62 move away from each other, a releasing effect is achieved.
[0033] There are four infusion pump limit assemblies 6 arranged in a straight line.
[0034] The surface of the clamping plate 62 is covered with a rubber layer.
[0035] By providing a rubber layer, violent impact during clamping can be avoided.
[0036] A card slot 11 is provided on one side of the table top of the operating table 1 at the middle position on both sides corresponding to the U-shaped rod 61.
