[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] Example:

[0026] See also Figure 1-Figure 2The utility model provides an infusion pump calibration device, including an infusion pump calibration device 1. A chamber 2 is provided on one side of the infusion pump calibration device 1. An inlet opening 3 is provided on the top of the chamber 2. An outlet opening 4 is provided on the bottom of the chamber 2. A pipe clamp device is installed at intervals in the chamber 2. The pipe clamp device is symmetrically installed. The pipe clamp includes a bracket 5, a roller 6 and a flexible rubber sleeve 7. The bracket 5 is fixedly connected to the inner plate surface of the chamber 2. The bracket 5 is movably installed with the roller 6 through a shaft. The outer part of the roller 6 is fixedly sleeved with a flexible rubber sleeve 7. There is a spacing between the pipe clamps in the same group.

[0027] Specifically, Figure 1 As shown, there are three groups of tube clamp devices. The upper group of tube clamp devices is arranged close to the insertion opening 3, the lower group of tube clamp devices is arranged close to the outlet opening 4, and the middle tube clamp device is arranged at a position between the insertion opening 3 and the outlet opening 4, replacing the position of the original plastic clamp, so as to facilitate the guidance and wiring of the infusion tube.

[0028] Specifically, Figure 2 As shown, the bracket 5 is a bent structure, which facilitates the suspended arrangement of the roller 6 and the flexible rubber sleeve 7 so that they can roll.

[0029] Specifically, Figure 2 As shown, the length of the flexible rubber sleeve 7 is smaller than that of the roller 6, which reduces the material consumption and reduces the cost.

[0030] Specifically, Figure 1 As shown, the body of the flexible rubber sleeve 7 is provided with an inner sleeve and an outer sleeve. The inner sleeve is fixedly mounted on the roller 6. A cavity is formed between the inner sleeve and the outer sleeve. The outer surface of the outer sleeve is provided with anti-skid particles. The flexible rubber sleeve 7 is elastic and easy to deform. The clamping force formed by rebound after deformation is greater. In addition, the provision of anti-skid particles allows the infusion tube to be clamped more stably and deformed less.

[0031] Working principle:

[0032] When in use, the infusion tube is passed through the insertion opening 3 and passed through the exit opening 4. The infusion tube section inside the chamber 2 is squeezed toward the spacing between the tube clamp devices. Since the roller 6 is movably installed, when the infusion tube is pressed, the infusion tube will push the flexible rubber sleeve 7 to roll, and the infusion tube can be inserted more smoothly. Due to the existence of the cavity and the deformable material of the flexible rubber sleeve 7, the flexible rubber sleeve 7 automatically deforms and adjusts, and the infusion tube is smoothly pressed into the plate surface of the contact chamber 2. At this time, the flexible rubber sleeve 7 has a reverse squeezing and clamping force on the infusion tube. Because its own material is soft, squeezing will not cause a large deformation of the infusion tube. The infusion tube is fixed with only a slight deformation, and the outer surface of the flexible rubber sleeve 7 is provided with anti-skid particles, which increase the friction force of clamping and fixing the infusion tube.

[0033] Take off the infusion tube and directly pull it outwards. Since the roller 6 can roll under force, there will be no large resistance when pulling it outwards.

[0034] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
