Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and more specifically to an insulin pen and needle designed to prevent needlestick injuries. Background Technology

[0002] Insulin pens are an important daily tool for diabetic patients, providing them with fast and stable drug injections to meet their daily needs.

[0003] Current insulin pens generally consist of a pen body and a disposable needle. When using them, the needle needs to be attached to the pen body and then removed and discarded after injection to reduce the risk of infection. However, most needles are currently connected to the pen body by a threaded rotation, which makes it easy to get pricked before and after disassembly, posing a certain safety risk. Therefore, this needs to be improved. Utility Model Content

[0004] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an insulin pen and needle that are resistant to needle stick injuries, which can achieve quick assembly and disassembly of the needle through a snap-fit ​​mechanism, thereby greatly reducing the risk of needle stick injuries.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] Needle-stick resistant insulin pens and needles include:

[0007] The needle includes a cap and a needle body, the needle body passing through the cap, and the cap having symmetrically arranged grooves on its outer side;

[0008] An insulin pen has a lever with a locking block formed at the front end of the pen. The locking block engages with a slot to secure the needle to the front end of the pen. The end of the lever away from the locking block forms a driving end, which drives the lever to move and control the locking block to separate from the slot.

[0009] As a further improvement of this utility model, the insulin pen includes a grip section and an operating section connected to each other. The operating section includes two symmetrically arranged arc-shaped pieces. One end of each arc-shaped piece is fixed to the end of the grip section. The sides of the two arc-shaped pieces are separated from each other to form an installation space. The rod is arranged corresponding to the installation space. The middle section of the rod is rotatably connected to the arc-shaped pieces and a torsion spring is provided at the connection. The torsion spring is used to drive the rod to swing inward.

[0010] As a further improvement of this utility model, the front end of the arc-shaped piece forms a contact surface, and the cap includes a limiting surface corresponding to the contact surface. When the limiting surface and the contact surface abut against each other, the locking block corresponds to the locking slot.

[0011] As a further improvement of this utility model, an alcohol swab is provided at the rear end of the cap.

[0012] As a further improvement of this utility model, the number of slots is multiple and arranged around the cap.

[0013] The beneficial effects of this utility model are:

[0014] 1. The needle can be quickly attached and detached by using a slot and a locking block, thereby reducing contact between the human body and the needle and reducing the risk of puncture wounds;

[0015] 2. Remote separation is achieved through the design of the rod and drive end, thereby avoiding contact with the needle during disassembly to prevent puncture. Attached Figure Description

[0019] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments. Identical components are indicated by the same reference numerals.

[0020] like Figure 1-2 As shown, the needle-proof insulin pen and needle 1 include a needle 1, which includes a cap 2 and a needle body 3. The needle body 3 is disposed through the cap 2, and the cap 2 has symmetrically provided slots 4 on its outer side.

[0021] It also includes an insulin pen, which has a lever 5. The lever 5 forms a locking block 6 at the front end of the insulin pen. The locking block 6 is used to engage with the slot 4 to fix the needle 1 to the front end of the insulin pen. Specifically, the locking block 6 is hemispherical, and the shape of the slot 4 corresponds to the locking block 6. The hemispherical locking block 6 can improve the stability of the connection. The end of the lever 5 away from the locking block 6 forms a driving end 7. The driving end 7 is used to drive the lever 5 to move in order to control the locking block 6 to separate from the slot 4.

[0022] Preferably, the insulin pen includes a grip section 8 and an operating section 9 connected to each other. The operating section 9 includes two symmetrically arranged arc-shaped pieces 10. One end of the arc-shaped piece 10 is fixed to the end of the grip section 8. The sides of the two arc-shaped pieces 10 are separated from each other, so that an installation space 11 is formed between the edges of the two arc-shaped pieces 10. The rod 5 is arranged corresponding to the installation space 11. A rotating rod is provided in the middle section of the rod 5. The two ends of the rotating rod are rotatably connected to the side walls of the two arc-shaped pieces 10 on both sides, and a torsion spring is provided at the connection. The torsion spring is used to drive the rod 5 to swing inward.

[0023] Preferably, the front end of the arc-shaped piece 10 forms a contact surface 12, and the cap 2 includes a limiting surface 13 corresponding to the contact surface 12. When the limiting surface 13 and the contact surface 12 abut against each other, the locking block 6 corresponds to the locking groove 4.

[0024] In use, pressing the drive end 7 causes the rod 5 to swing outward at one end corresponding to the locking block 6, further connecting the cap 2 to the operating section 9, causing the limiting surface 13 to abut against the contact surface 12. Further releasing the drive end 7 causes the locking block 6 to engage with the slot 4 under the action of the torsion spring, thus completing the fixed limiting of the cap 2. After use, pressing the drive end 7 causes the locking block 6 to separate from the slot 4, thereby achieving automatic detachment of the needle 1 to avoid the risk of puncture wounds caused by operator contact.

[0025] Preferably, the cap 2 has an alcohol swab 14 at its rear end. The alcohol swab 14 allows operators to disinfect the tip of the insulin pen in advance, thereby further reducing the risk of infection.

[0026] Preferably, there are multiple slots 4 arranged around the cap 2, and the arrangement of multiple slots 4 facilitates the engagement of the card block 6 with the slots 4.

[0027] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
