[0018] like Figures 1 to 7As shown, an infusion set anti-dislodgement device includes: a fixing shell 1, which is open at one end, with a groove 101 on the outer side and a limiting groove 102 inside the fixing shell 1, the opening of which faces the open end of the fixing shell 1; and a limiting component, disposed on the outer side of the fixing shell 1, for limiting the position of the infusion needle, the limiting component including a fixing member 2 and a limiting member 3, the fixing member 2 being disposed inside the fixing shell 1 for installing the infusion needle, and the limiting member 3 being disposed on the outer side of the fixing shell 1 for connecting the infusion bottle, and the fixing member 2 cooperating with the limiting member 3 to... The injection needle is secured in the following manner: During the use of the infusion set, the injection needle is first installed inside the fixing shell 1 using the fixing component 2. During installation, it is necessary to ensure that the tip of the injection needle faces the medicine bottle. Then, the fixing shell 1 is connected to the medicine bottle using the limiting component 3 to prevent the injection needle from slipping under force and to ensure the stability of the injection needle during use. The size of the limiting groove 102 is adapted to the outer diameter of the injection needle, and it can limit the injection needle from the circumference during use, further restricting the radial movement of the injection needle inside the fixing shell 1 and ensuring the stability of the injection needle position during use.

[0019] like Figures 1 to 7 As shown, the fixing component 2 includes multiple limiting plates 202, each in a semi-circular shape. A limiting block 203 is provided on the outer side of each limiting plate 202, positioned on its sidewall. A fixing block 103 is rotatably connected to the outer side of the limiting plate 202 and is connected to the fixing shell 1. A connecting groove 104 is provided inside the fixing block 103, and the limiting block 203 slides within the connecting groove 104. A slot is provided on the opposite side of the limiting plate 202. Specifically, when installing a medicine needle, first align the needle tube of the medicine needle with the slot on the opposite side of the limiting plate 202, ensuring that the axis of the medicine needle coincides with the central axis of the slot. Then, place the medicine needle inside the slot. A flexible rubber pad can be provided on the inner wall of the slot to prevent scratching damage to the medicine needle and to enhance the clamping friction. Then, the limiting plate 202 is pushed simultaneously. Plate 202 is used to move the limiting plate 202 towards the medicine needle, tightly clamping the medicine needle inside the slot. Then, the limiting plate 202 is controlled to move into the fixed shell 1, so that the limiting block 203 is fully inserted into the connecting groove 104. The axial limitation of the limiting plate 202 is achieved by the engagement of the limiting block 203 and the connecting groove 104. At the same time, the limiting plate 202, together with the limiting groove 102, limits the medicine needle from both the periphery and the axis, preventing the medicine needle from moving relative to the fixed shell 1 during use. Multiple limiting plates 202 are connected by hinges. The rotation angle of the hinges can meet the clamping requirements of the limiting plates 202 from opening to closing. There are also connecting buckles between the limiting plates 202. After the limiting plate 202 has finished clamping the medicine needle, the connecting buckles are engaged to further fix the position of the limiting plate 202 and ensure the stability of the limiting plate 202 clamping the medicine needle.

[0020] like Figures 1 to 7 As shown, the limiting member 3 includes a fixing sleeve 301, which is sleeved on the outside of the fixing shell 1. The side wall of the fixing sleeve 301 has multiple sliding grooves 305. A sliding frame 302 is slidably connected inside each sliding groove 305. A rack 308 is provided inside the sliding frame 302. A gear 309 meshes with the outside of the rack 308 and rotates inside the fixing sleeve 301. A rotating rod 303 is provided outside the gear 309, with one end of the rotating rod 303 penetrating the fixing sleeve 301. The rotating part is rotated, and a pressure plate 304 is provided at the end of the rotating rod 303. A spring 307 is provided between the sliding frame 302 and the sliding groove 305. Specifically, when the medicine needle is inserted into the medicine bottle, the end of the sliding frame 302 is first pressed with a finger, causing the sliding frame 302 to move towards each other along the sliding groove 305. The moving sliding frame 302 drives the internal rack 308 to move synchronously. The rack 308 drives the gear 309 to rotate inside the fixed sleeve 301 through the meshing relationship with the gear 309. The gear 309 then drives the rotating rod 307 fixedly connected to it. 03 and pressure plate 304 rotate synchronously, causing pressure plate 304 to rotate away from the central axis of fixed sleeve 301. This prevents interference between pressure plate 304 and the bottle opening or body during the insertion of the medicine needle, ensuring that the medicine needle can be smoothly inserted into the rubber stopper of the medicine bottle. After the medicine needle is inserted, ensure that the needle tip is fully inside the medicine bottle and in a stable position. At this time, release the pressure on sliding frame 302. Spring 307 generates a restoring force due to the previous compression, pushing sliding frame 302 to move in the opposite direction along sliding groove 305. The moving frame 302 drives the rack 308 to move in the opposite direction. The rack 308 then drives the gear 309 to rotate in the opposite direction. The gear 309 drives the rotating rod 303 and the pressure plate 304 to rotate in the opposite direction, causing the pressure plate 304 to rotate towards the medicine bottle until the inner side of the pressure plate 304 is in close contact with the body of the medicine bottle. The inner side of the pressure plate 304 can be provided with anti-slip texture to enhance the friction with the medicine bottle, thereby limiting the position of the medicine needle during use and preventing the medicine needle from falling out of the medicine bottle. The fixing sleeve 301 and the fixing shell 1 can be connected by threads or buckles.

[0021] like Figures 1 to 7As shown, a guide rod 306 is also slidably connected inside the sliding frame 302. One end of the guide rod 306 is connected to the fixed sleeve 301, and the sliding direction of the sliding frame 302 is perpendicular to the axis of the rotating rod 303. Specifically, the shape of the guide rod 306 is not limited; it can be cylindrical, square, or hexagonal. However, its cross-sectional dimensions must match the dimensions of the sliding hole inside the sliding frame 302 to ensure that the guide rod 306 can slide smoothly inside the sliding frame 302, while preventing the sliding frame 302 from shaking during the sliding process. The length of the guide rod 306 can cover the maximum sliding stroke of the sliding frame 302. When the sliding frame 302 moves along the sliding groove 305, the guide rod 306 can guide it from inside the sliding frame 302, restricting the sliding frame 302 from moving in the set sliding direction. This prevents the sliding frame 302 from deviating due to force, thus ensuring that the rack 308 and gear 309 mesh stably. This ensures that the rack 308 meshes stably with the gear 309, thereby ensuring that the transmission process of the entire limiting member 3 is stable and reliable, and avoiding the effect of limiting the medicine needle due to transmission failure.

[0022] like Figures 1 to 7 As shown, at least one anti-slip groove is also provided on the outer side of the fixing sleeve 301. Specifically, the anti-slip groove can be in various shapes such as strip, mesh, or dot. The groove is preferably located in the middle of the outer side of the fixing sleeve 301 or in an area that is easily accessible to the operator when holding the device. During use, when the operator needs to install or remove the fixing sleeve 301 or adjust the position of the limiting member 3, the fingers contact the anti-slip groove on the outer side of the fixing sleeve 301. The anti-slip groove can increase the friction between the fingers and the outer side of the fixing sleeve 301, preventing the fingers from slipping during operation. This ensures that the operator can stably control the fixing sleeve 301 and avoids the fixing sleeve 301 from falling off or the limiting member 3 from being misadjusted due to slipping during operation, thereby ensuring the overall stability of the infusion set anti-dislodgement device.

[0023] like Figures 1 to 7 As shown, the end of the limiting plate 202 is also provided with a fixing clip 201. There are multiple fixing clips 201, and each fixing clip 201 corresponds to one of the limiting plates 202. Specifically, the fixing clips 201 and the limiting plates 202 are manufactured using an integral molding process, and the material can be medical-grade plastic, which ensures the firmness of the connection between the fixing clips 201 and the limiting plates 202 and prevents the fixing clips 201 from falling off during use. The fixing clips 201 have an arc-shaped structure, and the inner arc of its inner side matches the outer arc of the needle tube of the medicine needle. With proper fit, when the limiting plate 202 clamps the medicine needle, the fixing clip 201 can fit tightly against the needle tube of the medicine needle, thereby increasing the contact area with the medicine needle and further enhancing the clamping force of the medicine needle to prevent the medicine needle from loosening. In addition, the outer side of the fixing clip 201 is provided with raised anti-slip texture, which makes it easy for the operator to use their fingers to pinch the fixing clip 201 to control the opening, closing and moving of the limiting plate 202, reducing the difficulty of operation and improving the efficiency of operation.

[0024] like Figures 1 to 7 As shown, the working state of this infusion set anti-dislodgement device is as follows: First, the limiting plate 202 in the fixing member 2 cooperates with the fixing clamp 201 to clamp the medicine needle in the slot of the limiting plate 202. Pushing the limiting plate 202 causes the limiting block 203 to slide into the connecting groove 104 of the fixing block 103. Combined with the limiting groove 102 inside the fixing shell 1, the medicine needle is axially and circumferentially limited in the fixing shell 1. Then, the sliding frame 302 in the sliding groove 305 on the side wall of the fixing sleeve 301 in the limiting member 3 is pressed. The sliding frame 302 drives the rack 308 to drive the gear 309 to rotate, so that the pressure plate 304 at the end of the rotating rod 303 moves away from the fixing. At the center of the fixed sleeve 301, after inserting the medicine needle into the medicine bottle through the opening end of the fixed shell 1, the sliding frame 302 is released, and the spring 307 pushes the sliding frame 302 to reset. The rack 308 drives the gear 309 and the rotating rod 303 in the opposite direction, so that the pressure plate 304 fits against the medicine bottle to achieve fixation. During this period, the guide rod 306 ensures that the sliding frame 302 slides smoothly. The anti-slip groove on the outside of the fixed sleeve 301 improves the stability of operation. When changing the medicine bottle, there is no need to disassemble the fixed shell 1 and the fixed sleeve 301. You only need to press the sliding frame 302 repeatedly to adjust the pressure plate 304. The whole system achieves the anti-dislodgement fixation of the medicine needle through the coordinated cooperation of the fixing part 2 and the limiting part 3.

[0025] In summary, this utility model includes: a fixing shell 1, which is open at one end, with a groove 101 on the outer side and a limiting groove 102 inside, the opening of which faces the opening of the fixing shell 1; and a limiting component, which is disposed on the outer side of the fixing shell 1 and used to limit the position of the medicine needle. The limiting component includes a fixing member 2 and a limiting member 3. The fixing member 2 is disposed inside the fixing shell 1 and used to install the medicine needle, while the limiting member 3 is disposed on the outer side of the fixing shell 1 and used to connect the medicine bottle. The fixing member 2 cooperates with the limiting member 3 to fix the medicine needle. Through the setting of the fixing shell 1 and the fixing member 2, this utility model achieves the cooperation of the fixing shell 1, the fixing block 103, the connecting groove 104, the fixing clip 201, the limiting plate 202, and the limiting block 203, thereby installing the fixing shell 1 and the fixing sleeve 301 on the outer side of the medicine needle during use, avoiding the need to disassemble and reassemble the fixing device when the medicine bottle is replaced.
