[0029] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0030] The terms "left," "right," "front," "back," "up," and "down" used in the following description refer to the orientation from the perspective of the front view.

[0031] Example 1: In some embodiments, please refer to the accompanying drawings. Figures 1-6 An infusion set for preventing leakage includes an infusion set 1. The puncture end of the infusion set 1 is connected to a leak-proof adjustment assembly 2 for adjusting insertion and removal and sealing the infusion bottle stopper. The leak-proof adjustment assembly 2 includes a leak-proof component 21 and an adjustment component 22, both connected to the infusion set 1. The leak-proof component 21 is connected to a pressurizing component 3 and a locking component 4. The pressurizing component 3 is used for pressure adjustment between the leak-proof component 21 and the infusion bottle stopper, and the locking component 4 is used for locking the leak-proof component 21 and the infusion bottle stopper.

[0032] In use, this invention uses the anti-leakage component 21 in conjunction with the infusion bottle stopper to prevent leakage of residual liquid from the infusion bottle. The adjustment component 22 drives the puncture end of the infusion set 1 to puncture and remove the infusion bottle stopper, thus making the removal process of the puncture end of the infusion set 1 controllable and further reducing the risk of drug leakage. The pressurization component 3 pressurizes the anti-leakage component 21 and the stopper, thereby increasing the air pressure between the anti-leakage component 21 and the infusion bottle stopper to prevent drug leakage. The locking component 4 locks the anti-leakage component 21 and the infusion bottle stopper together, thus preventing them from falling off.

[0033] In this embodiment, the infusion set 1 includes an infusion set body 11 and a puncture assembly 12. The puncture assembly 12 is connected to the top tubing of the infusion set body 11, and is also connected to the leak-proof assembly 21 and the adjustment assembly 22. Specifically, the puncture assembly 12 includes a puncture needle 121, a mounting sleeve 122, and a sliding column 123. The bottom end of the puncture needle 121 is connected to the top tubing of the infusion set body 11. The mounting sleeve 122 is fixedly installed on the outside of the puncture needle 121, and the sliding column 123 is fixedly installed on the outer wall of the mounting sleeve 122. Both the mounting sleeve 122 and the sliding column 123 are connected to the adjustment assembly 22, and the puncture needle 121 is connected to the leak-proof assembly 21.

[0034] In this embodiment, the leak-proof component 21 includes a sealing rubber cover 211, a through hole 212, a sealing ring 213, and an annular groove 214. The inner bottom wall of the sealing rubber cover 211 has a through hole 212. The sealing ring 213 is fixedly installed on the inner bottom wall of the sealing rubber cover 211 and is located around the through hole 212. The annular groove 214 is opened on the top outer wall of the sealing rubber cover 211. The annular groove 214 is used in conjunction with the locking component 4. The through hole 212 is used for the puncture needle 121 to pass through. The inner wall of the sealing ring 213 is in close contact with the outer wall of the puncture needle 121 and is slidably connected. The adjusting component 22 is connected to the bottom of the sealing rubber cover 211.

[0035] The adjustment assembly 22 includes a rotating sleeve 221, an inclined groove 222, a knob sleeve 223, a limiting sleeve 224, and a limiting groove 225. The rotating sleeve 221 is rotatably connected to the bottom of the sealing rubber cover 211, and the rotating sleeve 221 is concentrically arranged with the through hole 212. The inclined groove 222 is opened through the outer wall of the rotating sleeve 221. The rotating sleeve 221 is rotatably sleeved on the outside of the limiting sleeve 224. The inclined groove 222 is fitted and slidably connected with the sliding column 123. The knob sleeve 223 is fixedly installed on the bottom outer wall of the rotating sleeve 221. The limiting sleeve 224 is fixedly installed on the bottom of the sealing rubber cover 211. The outer wall of the mounting sleeve 122 is slidably connected to the inner wall of the limiting sleeve 224. The outer wall of the limiting sleeve 224 is provided with a limiting groove 225 for use in the limiting sliding connection with the sliding column 123.

[0036] When this utility model is in use, by rotating the knob sleeve 223, the knob sleeve 223 drives the rotating sleeve 221 to rotate. The inclined groove 222 on the rotating sleeve 221 rotates and drives the sliding column 123 to move vertically. The sliding column 123 slides up and down along the limiting groove 225. The mounting sleeve 122 drives the puncture needle 121 to move up and down, thereby realizing the controllable insertion and removal of the puncture needle 121, thus avoiding the leakage of medicine in the infusion bottle caused by the puncture needle 121 being pulled out too quickly.

[0037] In this embodiment, the pressurization component 3 includes a second through hole 31, an air tube 32, and a syringe 33. The second through hole 31 is opened through the outer wall of the sealing rubber cover 211. One end of the air tube 32 is fixedly connected to the second through hole 31, and the other end of the air tube 32 is connected to the injection port of the syringe 33.

[0038] When this utility model is used, the gas in the syringe 33 is injected into the sealing rubber cap 211 along the air tube 32 and the through hole 31, thereby increasing the air pressure in the sealing rubber cap 211. The increased air pressure in the sealing rubber cap 211 prevents leakage of the medicine in the infusion bottle.

[0039] In this embodiment, the locking assembly 4 includes a metal clamp 41, a threaded sleeve 42, and a threaded knob 43. The metal clamp 41 is fitted into the annular groove 214. The threaded sleeve 42 is fixed to one side of the notch on the metal clamp 41. One end of the threaded knob 43 is threaded through the threaded sleeve 42 and rotatably connected to the other side of the notch on the metal clamp 41.

[0040] In use, the metal clamp 41 is fitted onto the annular groove 214, and the sealing rubber cap 211 is placed on the outside of the infusion bottle stopper. Then, the threaded knob 43 is rotated, and the threaded knob 43 and the threaded sleeve 42 move together, causing the two ends of the notch on the metal clamp 41 to move closer together, thereby locking the metal clamp 41 onto the annular groove 214. The annular groove 214 locks the sealing rubber cap 211 onto the infusion bottle stopper.

[0041] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of this utility model.
