[0033] Example 1
[0034] This embodiment provides an insulin pen needle remover 100, such as Figures 1 to 5As shown, it includes a needle cap 10 and an ejector pin device 20; the needle cap 10 has an insertion fixing groove and an ejector pin cavity 14 connected in sequence, and the insertion fixing groove is opened at one end away from the ejector pin cavity 14 for inserting the insulin pen injection needle; a limiting portion is provided in the insertion fixing groove, which can limit the insulin pen injection needle located in the insertion fixing groove from rotating around the axis of the needle cap 10; the tip 200 of the insulin pen injection needle can be located in the ejector pin cavity 14; an internal threaded hole 15 is provided at the end of the ejector pin cavity 14 away from the insertion fixing groove; two symmetrical rotating handles 16 are fixedly provided on the outer side wall of the end of the needle cap 10 having the internal threaded hole 15; the ejector pin The device 20 includes a thimble handle 21, a thimble rod 22 and a thimble push plate 23; the thimble handle 21 is located outside the needle cap 10 at one end having the thimble cavity 14; the thimble push plate 23 is located in the thimble cavity 14; the thimble rod 22 is inserted into the internal threaded hole 15, and one end of the thimble rod 22 is fixedly connected to the thimble handle 21, and the other end of the thimble rod 22 is connected to the thimble push plate 23; an external thread threadedly connected to the internal threaded hole 15 is provided on the outer wall of the thimble rod 22; after the thimble rod 22 and the internal threaded hole 15 are threadedly rotated, the thimble rod 22 can drive the thimble push plate 23 to push the end 200 of the insulin pen injection needle toward the side close to the insertion fixing groove.
[0035] By inserting the insulin pen injection needle into the insertion fixing groove in the needle cap 10, holding the insulin pen barrel with one hand and holding the two symmetrical rotating handles 16 with the other hand, the internal insulin pen injection needle and the needle cap 10 are rotated synchronously based on the limiting part in the insertion fixing groove, so that the insulin pen injection needle is unscrewed from the insulin pen barrel and aligned with the sharps bucket, and the ejector handle 21 is rotated to realize the ejector push plate 23 to push the end 200 of the internally screwed-down insulin pen injection needle, so that the unscrewed insulin pen injection needle is detached from the needle cap 10 and falls into the sharps bucket; during the whole process, the hand will not touch the insulin pen injection needle, which can effectively reduce the risk of clinical nurses being stabbed and protect personal safety; through the two symmetrical rotating handles 16, it can be conveniently operated with one hand, so that the insulin pen barrel can be held in one hand and the device can be held in the other hand to quickly remove the injection needle.
[0036] Among them, the relevant structure description of the needle cap 10 is as follows:
[0037] Among the optional solutions of this embodiment, it is more preferred that Figure 2 and Figure 4As shown, the insertion slot and ejector cavity 14 are connected via a needle hole 13. The insulin pen needle can be slidably inserted into the needle hole 13, and the distal end 200 of the insulin pen needle can pass through the needle hole 13 and be located within the ejector cavity 14. The provision of the needle hole 13 enables the needle portion of the insulin pen needle to be stably located within the needle hole 13, thereby ensuring that the ejector push plate 23 is more stable and reliable when pushing it.
[0038] Among the optional solutions of this embodiment, it is more preferred that Figure 2 As shown, the insertion fixing groove includes a first limiting groove 11 and a second limiting groove 12 that are connected in sequence. One end of the first limiting groove 11 is open for inserting the insulin pen needle.

The circumferential inner wall of the second limiting groove 12 is provided with limiting grooves 121 that match the ridges 201 at corresponding positions on the insulin pen needle. The limiting grooves 121 together form a limiting portion. The insertion fixing groove is formed by the first limiting groove 11 and the second limiting groove 12 that match the shape of the insulin pen needle. This ensures that the insulin pen needle is more stably and securely positioned in the insertion fixing groove. The limiting grooves 121 on the second limiting groove 12 cooperate with the ridges 201 at corresponding positions on the insulin pen needle to limit its circumferential rotation. The structure is simple and stable.
[0039] Among them, the relevant structural description of the ejector device 20 is as follows:
[0040] Specifically, the axes of the ejector rod 22, the ejector push plate 23, the ejector cavity 14, the insertion fixing groove and the needle through-hole 13 are coaxial.
[0041] Among them, regarding other related instructions:
[0042] Among the optional solutions of this embodiment, it is more preferred that Figure 1 、 Figure 3 and Figure 4 As shown, the overall shape formed by the two rotating handles 16 is the same as the shape of the thimble handle 21. The overall shape of the two rotating handles 16 is the same as the shape of the thimble handle 21, thereby ensuring a good grip effect.
[0043] Specifically, the two rotating handles 16 are fixed on the outer side wall of the needle cap 10 to form a diamond shape. Figure 1 and Figure 3 、 Figure 4 shown.
[0044] In an alternative embodiment of this embodiment, an elastic layer is preferably fixedly disposed on the inner circumferential sidewall of the first retaining groove 11.

[0046] Specifically, in order to ensure that the part of the insulin pen injection needle corresponding to the first limiting groove 11 can smoothly enter the first limiting groove 11, the opening of the first limiting groove 11 can be set to a conical hole shape, that is, the opening on one side is larger, and the inner diameter of the other side opening is slightly smaller than the outer diameter of the corresponding position of the insulin pen injection needle.
[0047] Specifically, in order to increase the speed with which the insulin pen needle can be inserted into the needle cap 10, the needle cap 10 can be made of a transparent material so that medical staff can more intuitively see whether the needle is inserted into place or not, thereby ensuring that the insulin pen needle can be screwed down smoothly.
[0048] Among the optional solutions of this embodiment, it is more preferred that Figure 5 As shown, a plurality of first limiting ridges are fixedly disposed on the inner sidewall of the first limiting groove 11, each of which corresponds to a groove 202 at a corresponding position on the insulin pen needle. The first limiting ridges disposed on the inner sidewall of the first limiting groove 11 can mate with the corresponding grooves on the insulin pen needle, thereby enhancing the circumferential rotational locking between the insulin pen needle and the needle cap 10 during screwing, thereby improving the screwing success rate.
[0049] Specifically, in order to improve the ability of the tip 200 of the insulin pen injection needle to be smoothly inserted into the needle perforation 13, a conical guide hole can be set between the second limiting groove 12 and the needle perforation 13, and one end of the conical guide hole is connected and communicated with one end opening of the second limiting groove 12, and the other end of the conical guide hole is connected and communicated with one end opening of the needle perforation 13.
