In addition, the terms "first", "second", "third" and the like are only used for descriptive purposes and cannot be understood as indicating or implying relative importance.

[0021] Example: See Figure 1 — Figure 4 The utility model provides a technical solution: an infusion set that can be prevented from being pulled out by external force, comprising a U-shaped frame 1, a circular groove 2 is provided on the top of the U-shaped frame 1, a bottle body 3 is connected to the inner cavity of the circular groove 2, threaded grooves 4 are provided on both sides of the middle of the U-shaped frame 1, threaded rods 5 are threadedly connected to the inner cavity of the threaded groove 4, a handle 6 is fixedly installed on one side of the two threaded rods 5, sliding grooves 8 are provided on both sides of the inner wall of the U-shaped frame 1, an infusion needle 9 is sleeved on the bottom of the bottle body 3, a connecting block 10 is provided in the middle of the infusion needle 9, sliders 11 are fixedly installed on both sides of the connecting block 10, an infusion tube 15 is sleeved on the bottom of the infusion needle 9, and a connecting needle 16 is provided on the bottom of the infusion tube 15.

[0022] Wherein, protective rings 7 made of rubber are fixedly installed on the other sides of the two threaded rods 5 .

[0023] In this embodiment, the bottle body 3 is connected to the U-shaped frame 1 through the circular groove 2, and then the two handles 6 can be rotated to drive the two threaded rods 5 to rotate clockwise in the two threaded grooves 4. The distance between the two threaded rods 5 is adjusted and fixed according to the diameter of the bottle body 3, so that the device can be used for bottles 3 of different diameters, thereby effectively improving the adaptability of the device.

[0024] The infusion needle 9 is fixedly connected to the connecting block 10 , and the connecting block 10 is slidably connected to the U-shaped frame 1 in the sliding groove 8 via the sliding block 11 .

[0025] The slider 11 and the U-shaped frame 1 are both provided with insertion grooves 12 on both sides of the front side, and the inner cavity of every two insertion grooves 12 is provided with a U-shaped insertion rod 13 , and a ring 14 is fixedly installed on the front side of the U-shaped insertion rod 13 .

[0026] In this embodiment, by fixedly connecting the infusion needle 9 with the connecting block 10, the infusion needle 9 can be inserted into the bottle body 3 when the connecting block 10 moves upward in the slide groove 8 through the slider 11, and then the U-shaped insertion rod 13 is inserted through the insertion groove 12 in the U-shaped frame 1 and the slider 11 by holding the ring 14, and the slider 11 is fixed in the slide groove 8. Therefore, when the infusion device is used, it can prevent the patient from being pulled out of the bottle body 3 when going to and from the toilet and during activities, and further prevent the adverse phenomenon of being contaminated by the environment and inserted back into the bottle body 3 to contaminate the drug solution and cause life-threatening to the patient.

[0027] The bottom of the infusion tube 15 is fixedly connected to the top of the connecting needle 16 .

[0028] In this embodiment, by positioning and fixing the infusion tube 15 and the connecting needle 16, the stability during use can be increased to prevent the infusion tube 15 from breaking due to shaking caused by the patient's shaking during use, resulting in inability to use normally.

[0029] The bottom of the bottle body 3 does not contact the top of the connecting block 10 and there is a certain distance between them.

[0030] In this embodiment, when the bottom of the bottle body 3 is set to not contact with the top of the connecting block 10 and to be separated by a certain distance, it can prevent the bottle body 3 from contacting, shaking and rubbing with the connecting block 10 for a long time during use by the patient, thereby preventing unnecessary wear on the connecting block 10.

[0031] Working principle: first, connect the bottle body 3 with the U-shaped frame 1 through the circular groove 2, and then rotate the two handles 6 to drive the two threaded rods 5 to rotate clockwise in the two threaded grooves 4, and adjust and fix the distance between the two threaded rods 5 according to the diameter of the bottle body 3, so that the device can be conveniently used for bottles 3 with different diameters, so that the adaptability of the device is effectively improved. When the connection is completed, the connecting block 10 can be moved upward in the slide groove 8 through the slider 11 to drive the infusion needle 9 to move synchronously and insert the infusion needle 9 into the bottle body 3, and then hold the ring 14 to insert the U-shaped insertion rod 13 through the insertion groove 12 in the U-shaped frame 1 and the slider 11, and fix the slider 11 in the slide groove 8, so that when the infusion device is used, it can prevent the patient from being pulled out of the bottle body 3 when going to and from the toilet and during activities, and thus prevent the adverse phenomenon of being contaminated by the environment and inserted back into the bottle body 3 to contaminate the drug solution and cause life endangerment to the patient.

[0032] In the description of the present invention, it is also necessary to explain that, unless otherwise clearly specified and limited, the terms "set", "install", "connect", and "connect" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be indirectly connected through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
