[0021] The following describes in detail embodiments of the present invention, examples of which are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the embodiments of the present invention, and should not be construed as limiting the present invention.

[0022] In the description of the embodiments of the present invention, it should be understood that the terms "length", "width", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", etc., indicating the orientation or position relationship, are based on the orientation or position relationship shown in the accompanying drawings, and are only for the convenience of describing the embodiments of the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation on the present invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be understood to indicate or imply relative importance or implicitly specify the number of the technical features indicated. Thus, features defined as "first" or "second" may explicitly or implicitly include one or more of the described features. In the description of the embodiments of the present invention, "plurality" means two or more, unless otherwise specifically defined. Example

[0024] Reference Figure 1 、 Figure 2This embodiment discloses an insulin pen needle remover, comprising a storage barrel 3 for storing insulin pen needles, and a barrel cover 1 disposed above the storage barrel 3. The barrel cover 1 is provided with a socket for inserting the insulin pen needle, and a movable rod 2 for clamping the insulin pen needle is movably disposed on the side wall of the barrel cover 1. The barrel cover 1 is divided into an upper cover 11 and a lower cover 12, which are connected by bolts. A restriction cavity is formed between the upper cover 11 and the lower cover 12, and the movable rod 2 extends through the restriction cavity. A first spring movably mounted on the movable rod 2 and a retaining ring fixedly mounted on the movable rod 2 are disposed within the restriction cavity, with the first spring located between the retaining ring and the restriction cavity. After a patient self-injects insulin, they insert the insulin pen needle into the socket. Because the overall device is relatively small, the patient can hold the storage barrel 3 with one hand and push the movable rod 2 inward until the movable rod 2 contacts the insulin pen needle. By turning the knob with one hand, the insulin pen needle falls into the storage barrel 3.

[0025] To prevent odors from accumulating in the storage bin 3, a silicone cross valve (similar in principle to a bicycle valve core) is installed inside the insertion hole on the lid 1. This valve is an inverted elastic membrane with a cross-shaped opening at its top. Normally, when unstressed, it is closed and gathered together. When an insulin pen needle is inserted into the insertion hole, the membrane deforms and opens outward, forming a passage. After the insulin pen needle is removed, the membrane elastically returns to its original position, sealing the opening and preventing odors from escaping the storage bin 3.

[0026] When the storage bucket 3 reaches approximately 30% capacity, the insulin pen needle and some of the liquid medicine inside need to be cleaned. The storage bucket 3 is detachably connected to the lid 1 via a threaded connection. When cleaning is necessary, simply lower the lid 1 and flip the storage bucket 3 over. This process eliminates the need for the patient to physically touch the insulin pen needle, making it safer and easier to use for middle-aged and elderly diabetics, significantly reducing the risk of needlestick injuries. Example

[0027] Reference Figure 3This embodiment discloses an insulin pen needle remover. Considering the need to clean contaminants such as insulin pen needles from the storage bucket 3 when its capacity reaches approximately 30%, a discharge device is provided based on the first embodiment. The discharge device includes a base plate 33 located at the bottom of the storage bucket 3, an adjustment frame 31 located outside the storage bucket 3, and an adjustment rod 32. The base plate 33 has a conical protrusion 331 in the middle. One end of the adjustment rod 32 is slidably connected to the adjustment frame 31, and the other end is connected to the base plate 33. A side opening is provided on the side wall of the adjustment frame 31. The top end of the adjustment rod 32 extends into the adjustment frame 31 and exits through the side opening. A second spring is provided within the adjustment frame 31 and is sleeved on the adjustment rod 32. The second spring is used to elastically reset the adjustment rod 32 after it slides down. When the storage bucket 3 reaches approximately 30% of its capacity, the adjustment rod 32 can be lowered, compressing the spring and driving the bottom plate 33 downward. The 331 on the bottom plate 33 allows the insulin pen needle to slide downward along the surface of the conical protrusion 331. After releasing the adjustment rod 32, the second spring resiliently resets the adjustment rod 32 and the bottom plate 33. Considering that the insulin needle inevitably carries some liquid medicine with it when it is removed, a sealing ring 332 is provided on the bottom plate 33 to prevent liquid medicine from leaking out. To prevent liquid medicine from leaking out, a sealing ring 332 is provided on the bottom plate 33, and an annular groove is provided on the bottom of the storage bucket 3 to accommodate the sealing ring 332. The sealing ring 332 blocks the gap between the storage bucket 3 and the bottom plate 33, largely preventing liquid medicine from leaking out. The structure is simple and easy to operate. Furthermore, since this discharge device only requires sliding the adjustment rod 32, it is located farther from the discharge point of the insulin pen needle. Compared to the method of turning down the lid 1 and flipping the storage bucket, as used in Example 1, this method further reduces the risk of needle stick injuries for middle-aged and elderly diabetic patients.

[0028] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
