[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figures 1 to 10 This utility model provides a technical solution: a detachable infusion regulator, including a first side combined shell 10 and a second side combined shell 11 that can be combined and separated from each other, and further including: a connecting structure, a guiding structure, an adjusting wheel 16, and a fitting cavity 18. The connecting structure is disposed on a contacting edge of the first side combined shell 10 and the second side combined shell 11, and the first side combined shell 10 and the second side combined shell 11 can rotate around the edge to realize the opening and closing action; the guiding structure is fixedly disposed on the inner wall surface of the first side combined shell 10 and / or the second side combined shell 11; the adjusting wheel 16 is movable along the guiding structure; the fitting cavity 18 is formed in the inner wall of the first side combined shell 10 and the second side combined shell 11, and the fitting cavity 18 is used to fit on the outer wall of the infusion tube, and the adjusting wheel 16 can move to different depth positions in the fitting cavity 18.

[0026] It should be noted that when the infusion regulator is needed, the first side combined housing 10 and the second side combined housing 11 can rotate freely through the connecting structure to complete the opening and closing action for subsequent operation. When adjusting the drug flow rate, the adjusting wheel 16 is moved along the guide structure. Due to the guiding function of the guide structure, the adjusting wheel 16 can stably move to the designated position. This allows it to move to different depths within the sleeve cavity 18 as needed, compressing the infusion tubing to adapt to different needs during the infusion process, ultimately achieving convenient and efficient use of the infusion regulator.

[0027] Please see Figures 1-6 The connecting structure includes a handle 12, the first part of which is fixed to the first side combined housing 10, and the second part of which is fixedly connected to the second side combined housing 11. The first part and the second part of the handle 12 can rotate relative to each other.

[0028] It should be noted that when preparing to use this detachable infusion regulator, the user holds the handle 12. Since the first and second parts of the handle 12 can rotate relative to each other, by applying a little force, the first side combined housing 10 and the second side combined housing 11 can rotate freely around their contact edges, smoothly completing the opening and closing action, and can be conveniently clamped on the outer wall of the infusion tube.

[0029] In some examples, the first and second parts of the grip 12 are rotatably connected by a pivot 17, and a torsion spring 13 is also sleeved on the outer wall of the pivot 17. The first and second ends of the torsion spring 13 abut against the inner walls of the first and second parts of the grip 12, respectively.

[0030] It should be noted that when preparing to use the infusion regulator, the first and second parts of the handle 12 are rotatably connected via a pivot 17. A torsion spring 13 is fitted onto the outer wall of the pivot 17. The first end of the torsion spring 13 is tightly abutted against the inner wall of the first part of the handle 12, and the second end is also tightly abutted against the inner wall of the second part of the handle 12. In the initial state, the torsion spring 13 uses its own elasticity to keep the handle 12 in an open angle. When the user reaches out and pinches the handle 12, overcoming the elasticity of the torsion spring 13, the first and second parts rotate relative to each other around the pivot 17, causing the first side combined housing 10 and the second side combined housing 11 to rotate flexibly around their contact edges, smoothly completing the opening and closing action and initiating the subsequent operation process. After the operation is completed, the handle 12 is released, and under the action of the torsion spring 13, the handle 12 will return to its initial relative position, ready for the next use.

[0031] Please see Figures 7-10 The connection structure includes multiple hinge seats 21. The first part of the hinge seat 21 is fixed on the first side combined housing 10, and the second part of the hinge seat 21 is fixed on the second side combined housing 11. The first part and the second part of the hinge seat 21 are rotatably connected by a hinge seat shaft 22.

[0032] It should be noted that when this detachable infusion regulator is ready to be used, the first side combined housing 10 and the second side combined housing 11 can rotate relative to each other with the hinge shaft 22 as the axis to smoothly complete the opening and closing action, wrapping the infusion tube in the sleeve cavity 18, and realizing the regulation of the flow rate of the medicine in the infusion tube.

[0033] Please see Figures 1-3 In some examples, the first side housing 10 is located on the side with the adjusting wheel 16, and the second side housing 11 is the other side that can be fastened into the first side housing 10.

[0034] The first side combined housing 10 is positioned on the side with the adjusting wheel 16. The adjusting wheel 16, which controls the flow rate of the infusion during the infusion process, is located on the guide structure on the inner wall of the first side combined housing 10. It relies on the first side combined housing 10 for stable support, allowing it to move along the guide structure to different depths within the sleeve cavity 18. This effectively adjusts the outer wall of the infusion tube fitted within the sleeve cavity 18 (composed of the first and second side combined housings 11), thereby controlling the infusion flow rate. The second side combined housing 11 can be fastened to the other side of the first side combined housing 10. Through connecting structures such as the hinge 21 and the handle 12, the two housings rotate around their edges, allowing the second side combined housing 11 to open and close flexibly. When open, it facilitates medical personnel in installing the infusion tube and adjusting the adjusting wheel 16. When fastened, it ensures the overall structure is stable, guaranteeing smooth and safe infusion.

[0035] Please see Figures 4-10 In some examples, the first side combined housing 10 is located on one side of the radial cross-section of the adjusting wheel 16, and the second side combined housing 11 is located on the other side of the radial cross-section of the adjusting wheel 16.

[0036] It should be noted that the adjusting wheel 16, as the core control component in the infusion process, is supported by the radial cross-section of the first side combined housing 10, providing a solid physical foundation for the adjusting wheel 16. The adjusting wheel 16 moves based on the guide structure on the inner wall of the first side combined housing 10. Since the two are closely adjacent in the radial cross-section, the shaking and deviation during the movement can be minimized, ensuring that the adjusting wheel 16 slides precisely along the guide structure to the ideal depth position in the sleeve cavity 18. This allows for appropriate pressure control on the outer wall of the infusion tube sleeved in the sleeve cavity 18 (which is formed by the two housings), thereby controlling the infusion flow rate.

[0037] Correspondingly, the second side combined housing 11 is located on the other side of the radial cross-section of the adjusting wheel 16. In the usage scenario, medical staff can rotate the two housings around the edge by using the connecting structure, such as the hinge 21 and the handle 12. The second side combined housing 11 can be flexibly opened from the other side of the radial cross-section of the adjusting wheel 16, providing sufficient operating space for medical staff to accurately place the infusion tube into the sleeve cavity 18 without hindering the subsequent adjustment of the adjusting wheel 16. When it is fastened again, it can quickly restore the stable structure, ensuring the stable and orderly progress of the infusion process.

[0038] Please see Figures 1-3The guide structure includes: two mounting seats 14, which are respectively fixedly mounted on the outer wall of the first side combined housing 10 and the outer wall of the second side combined housing 11, and the positions of the two mounting seats 14 are corresponding; at least one inclined groove 15 is opened on the inner wall of the mounting seat 14, and the adjusting wheel 16 is movably engaged in the inclined groove 15. The distance between the inclined groove 15 and the sleeve cavity 18 is different at different positions.

[0039] It should be noted that the two mounting seats 14 serve as basic supports. One mounting seat 14 is firmly fixed to the outer wall of the first side combined housing 10, while the corresponding mounting seat 14 is firmly fixed to the outer wall of the second side combined housing 11. The two positions correspond precisely, and the distance between the inclined groove 15 and the sleeve cavity 18 varies. The adjusting wheel 16 is engaged in the inclined groove 15. Due to the inclined setting of the inclined groove 15, a moving path is formed for the adjusting wheel 16. When it is necessary to adjust the infusion flow rate, the adjusting wheel 16 is pushed and moves along the inclined angle of the inclined groove 15. According to the different distances between the inclined groove 15 and the sleeve cavity 18, the adjusting wheel 16 can move precisely to the appropriate position, thereby applying accurate control force to the outer wall of the infusion tube sleeved in the sleeve cavity 18 (which is jointly surrounded by the two housings), ensuring that the infusion process is stable and accurate according to the requirements.

[0040] Please see Figures 7-10 Two snap-fit ​​posts 19 are installed on the inner side of the first side combined housing 10, and two snap-fit ​​slots 20 are installed on the inner side of the second side combined housing 11. The two snap-fit ​​posts 19 and the two snap-fit ​​slots 20 are matched with each other.

[0041] It should be noted that there are two locking posts 19 on the inner side of the first side combined housing 10, and two locking slots 20 corresponding to the locking posts 19 are provided on the inner side of the second side combined housing 11. The shape and size of the locking slots 20 match the locking posts 19. When preparing to close the infusion regulator, hold the second side combined housing 11 and slowly bring it close to the first side combined housing 10. As the two housings gradually approach each other, the two locking posts 19 on the inner side of the first side combined housing 10 will slowly align with the two locking slots 20 on the inner side of the second side combined housing 11. Due to their mutual matching, the locking posts 19 can smoothly slide into the locking slots 20, and the two housings are tightly connected together to form a stable overall structure. This not only effectively protects the internal components, such as the adjusting wheel 16 and the guide structure, but also provides a reliable closed environment for the infusion process, ensuring smooth infusion.
