[0020] To make the objectives, technical solutions, and advantages of this utility model clearer, the following provides a more detailed description of the utility model. It should be understood that the specific embodiments described herein are merely illustrative and not intended to limit the scope of the utility model.

[0021] Please see Figure 1-6 This utility model provides a technical solution:

[0022] An insulin needle removal tool kit includes an insulin pen 1. A needle sleeve assembly 2 is fitted onto the top of the insulin pen 1. The needle sleeve assembly 2 includes a needle sleeve head 21. Several sets of grooves 211 are formed around the outer side of the needle sleeve head 21. Several sets of limiting grooves 212 are formed on the upper surface of the needle sleeve head 21. A removal assembly 3 is inserted into the top of the needle sleeve assembly 2. The removal assembly 3 includes a retainer 31. Several sets of protrusions 311 are fixedly installed around the inner wall of the retainer 31. The protrusions 311 are inserted into the grooves 211. A rotating assembly 4 is threaded onto the outer side of the retainer 31. The rotating assembly 4 includes a rotating sleeve 41. The retainer 31 is threaded into the rotating sleeve 41. A fixing rod 42 is fixedly installed in the middle of the rotating sleeve 41. A support base 44 is fitted onto the bottom of the fixing rod 42. A limiting block 45 is movably installed at the end of the support base 44. The limiting block 45 is inserted into the limiting groove 212.

[0023] In this embodiment, the needle sheath head 21 of the needle sheath assembly 2 is fitted onto the top of the insulin pen 1 to protect and fix the needle tip 22. A groove 211 is formed on the outside of the needle sheath head to cooperate with the protrusion 311 on the inner wall of the retainer 31 of the release assembly 3. The protrusion 311 on the inner wall of the retainer 31 is inserted into the groove 211 to provide friction during rotation. The release assembly 3 and the needle sheath head 21 achieve a quick and stable connection through the cooperation of the protrusion 311 and the groove 211, which facilitates quick installation and removal by medical personnel. A limiting groove 212 is formed on the upper surface of the needle sheath head 21 and cooperates with the limiting block 45 of the rotating assembly 4 to limit the rotation angle. The external thread of the rotating sleeve 41 of the rotating assembly 4 cooperates with the retainer 31 to realize the rotation function. The fixing rod 42 connects the rotating sleeve 41 and the support base 44 to provide structural stability. The support base 44 provides the axis of support and rotation. The limiting block 45 is movably installed at the end of the support base 44 and is inserted into the limiting groove 212 to limit the rotation range. This ensures the locked state of the components. The locking mechanism of the limiting block 45 and the limiting groove 212 together ensures the stability of the entire component during rotation, avoiding operational errors caused by shaking or misalignment. The rotation function of the rotating component 4 allows medical staff to remove the needle 22 with a simple rotation action, which is more time-saving and labor-saving compared to the traditional manual removal or cutting method. Through the solid connection between the removal component 3 and the needle sheath 21, and the locking mechanism of the rotating component 4, the stability of the needle 22 during the removal process is ensured, reducing the possibility of the needle 22 falling off or splashing, and further improving safety. The detachable design between components makes cleaning and maintenance easier. Medical staff can easily disassemble each component for thorough cleaning and disinfection to ensure the hygiene and safety of the equipment. This not only improves the work efficiency of medical staff, but also reduces the safety risks faced by medical staff, providing safer and more efficient insulin injection services for diabetic patients.

[0024] Specifically, the top of the support base 44 is provided with a fixing groove 441, the inside of the fixing groove 441 is provided with a rotating shaft 442, the limiting block 45 is rotatably installed in the middle of the rotating shaft 442, the bottom wall of the limiting block 45 is fixedly provided with a second protrusion 451, the top of the limiting groove 212 is fixedly installed with a first protrusion 213, and the second protrusion 451 is adapted to the size of the first protrusion 213.

[0025] In this embodiment, the design of the fixing groove 441 and the rotating shaft 442 provides a stable rotation axis for the limiting block 45, ensuring the stability of the limiting block 45 during rotation and avoiding operational errors caused by shaking or misalignment. The second protrusion 451 and the first protrusion 213 are rubber protrusions, and the dimensions of the second protrusion 451 and the first protrusion 213 are matched, which can make the second protrusion 451 and the first protrusion 213 fit tightly, increasing the friction between the limiting block 45 and the limiting groove 212, so that the limiting block 45 can fit tightly against the top of the limiting groove 212 when rotated to a specific position, thereby realizing a more reliable locking mechanism. This not only improves the stability of the locking, but also reduces the safety risks caused by loose locking. By rotating the limiting block 45, medical staff can easily lock and unlock the components without using additional tools or force, which not only simplifies the operation process, but also improves work efficiency. This not only improves the functionality and safety of the entire sharps box, but also provides medical staff with a more convenient, comfortable and efficient user experience.

[0026] Specifically, the outer wall of the ferrule 31 is provided with an external thread 312, and the inner wall of the swivel 41 is provided with an internal thread 411. The external thread 312 and the internal thread 411 are compatible.

[0027] In this embodiment, the tight fit between the external thread 312 and the internal thread 411 ensures that the rotational connection between the ferrule 31 and the rotating sleeve 41 is both stable and reliable. This threaded connection method can prevent relative sliding or misalignment between components during rotation, thereby ensuring the stability and safety of the entire sharps box during use. By rotating the rotating sleeve 41, medical staff can easily connect and disconnect the ferrule 31 and the rotating sleeve 41. The entire sharps box can maintain stable performance during use, reducing costs caused by frequent replacement or maintenance.

[0028] Specifically, a fixing block 422 is provided at the top of the fixing rod 42, and crossbars 43 are fixedly installed on both sides of the fixing block 422.

[0029] In this embodiment, the fixing block 422 and the crossbars 43 on both sides provide additional support for the connection between the rotating sleeve 41 and the support base 44, enhancing the structural stability of the entire assembly and preventing deformation or damage that may occur during rotation or use. The design of the crossbars 43 helps to disperse the stress generated during rotation, reducing the risk of wear or breakage caused by stress concentration. The crossbars 43 can also serve as operating handles, making it easier for medical staff to rotate the rotating sleeve 41, improving the convenience of operation and reducing fatigue or errors caused by difficult operation.

[0030] Specifically, a needle 22 is provided at the center of the top of the needle sleeve 21, and a limiting needle hole 421 is provided at the top of the fixing rod 42, the limiting needle hole 421 being adapted to the size of the needle sleeve 21.

[0031] In this embodiment, the needle 22 is located at the top center of the needle sleeve 21, ensuring that when the insulin pen 1 is inserted into the needle sleeve 21, the needle 22 can be accurately aligned with the needle limiting hole 421, improving the accuracy and reliability of the operation and reducing injection errors caused by the positional deviation of the needle 22. The size of the needle limiting hole 421 is adapted to the size of the needle sleeve 21, so that when the needle 22 passes through the needle limiting hole 421, it can be tightly fixed, preventing the needle 22 from shaking or falling off during use, and ensuring the safety and stability of the injection.

[0032] The above embodiments are only used to illustrate the technical solution of this utility model, and are not intended to limit it.
