[0002] In the medical field, the number of diabetic patients continues to grow, and insulin injection has become an important means for many patients to control their blood sugar. Insulin pens are widely used in insulin injection therapy due to their advantages such as ease of operation and precise dosage. Existing insulin injection needles and insulin pens are usually connected by threads. To ensure medical safety, the needles must be disposable. This means that after each insulin injection, the needle must be removed from the insulin pen and properly disposed of. To ensure a tight seal during injection, the needle cap is tightened very tightly when attaching the needle. When it is necessary to remove the needle, medical staff often have to spend a lot of time and effort to tighten it. The needle removal process is slow and laborious, which not only affects work efficiency but also greatly increases the workload of medical staff. Furthermore, improper operation may lead to needlestick injuries, which not only cause physical pain to medical staff but also increase the risk of occupational exposure and infection. Therefore, improvements are needed. Utility Model Content

[0014] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] like Figures 1 to 6 As shown, this utility model provides a needle removal device, including an insulin pen 1. An injection needle 2 is threadedly sleeved on the front end of the insulin pen 1. A driven toothed ring 9 is fixedly sleeved on the outer surface of the injection needle 2. A rotating toothed ring 10 is meshed with the front end of the driven toothed ring 9. A rotating block 11 is fixedly sleeved on the outer surface of the rotating toothed ring 10. A housing 3 is movably sleeved on the outer surface of the rotating block 11. A hinge block 4 is fixedly installed on the outer surface of the housing 3. A rotating rod 5 is hinged inside the hinge block 4. An arc-shaped block 6 is fixedly installed on the outer surface of the rotating rod 5. The arc-shaped block 6 is movably connected to the interior of the outer surface of the housing 3.

[0016] When the insulin pen 1 is inserted into the housing 3, the injection needle 2 and the driven toothed ring 9 will move forward along the inside of the housing 3 driven by the insulin pen 1. Subsequently, the front end of the driven toothed ring 9 will contact the rear end of the rotating toothed ring 10 during this movement. Due to the design of the driven toothed ring 9 and the rotating toothed ring 10, they will mesh with each other when they contact. When the operator holds the four rotating rods 5 and presses them, the four rotating rods 5 will drive the four arc-shaped blocks 6 to rotate around the four hinge blocks 4. When the four arc-shaped blocks 6 contact the insulin pen 1 during rotation, they will apply pressure to the insulin pen 1. When clamped and fixed, if the rotating block 11 rotates, it will drive the driven toothed ring 9 and the injection needle 2 to rotate through the rotating toothed ring 10. Since the injection needle 2 is threadedly connected to the outer surface of the insulin pen 1, the injection needle 2 will move forward along the outer surface of the insulin pen 1 while rotating. During this process, the injection needle 2 will squeeze and push the rotating block 11 through the driven toothed ring 9 and the rotating toothed ring 10, so that the rotating block 11 moves backward along the inside of the outer shell 3. Then the injection needle 2 will separate from the insulin pen 1 during the forward movement, which makes it easier for the operator to disassemble the injection needle 2.

[0017] Among them, a first spring 7 is fixedly installed on the outer surface of the rear end of the arc-shaped block 6, and the bottom end of the first spring 7 is fixedly connected to the outer surface of the outer shell 3.

[0018] When the rotating rod 5 rotates around the hinge block 4, it will compress the first spring 7. Due to the design of the first spring 7, it will have a good restoring effect on the movement of the rotating rod 5.

[0019] The outer casing 3 has a positioning block 8 fixedly installed inside, and the outer surface of the positioning block 8 is in contact with the outer surface of the insulin pen 1.

[0020] Due to the design of the positioning block 8, it will play a good guiding role for the insulin pen 1, so that the insulin pen 1 can always be located in the center inside the outer shell 3.

[0021] Among them, a ring 12 is movably sleeved inside the front of the rotating block 11, and a second spring 13 is fixedly installed on the front of the ring 12. The front end of the second spring 13 is fixedly connected to the inside of the outer shell 3.

[0022] Since the outer surface of the ring 12 is in a movable connection with the inside of the rotating block 11, the ring 12 and the second spring 13 will be unaffected by the rotation of the rotating block 11. When the rotating block 11 moves backward along the inside of the outer shell 3, it will compress the second spring 13 through the ring 12. Due to the design of the second spring 13, it will play a good restoring role for the movement of the rotating block 11.

[0023] Among them, a square rod 14 is fixedly installed on the front of the rotating block 11, a screwing block 15 is movably sleeved on the outer surface of the square rod 14, and a fixing ring 16 is movably sleeved on the back of the screwing block 15. The back of the fixing ring 16 is fixedly connected to the front end of the outer shell 3.

[0024] Since the rotating block 15 is movably sleeved with the outer surface of the fixed ring 16, when the operator rotates the rotating block 15, it will rotate around the sleeve point with the fixed ring 16 as the axis. Since the square rod 14 adopts a square design, the square rod 14 will rotate under the drive of the rotating block 15. At the same time, the square rod 14 will drive the rotating block 11 to rotate. Since the outer surface of the square rod 14 is movably sleeved with the inside of the rotating block 15, when the rotating block 11 moves forward, it will drive the square rod 14 to move forward along the inside of the rotating block 15.

[0025] The outer surface of the twisting block 15 is coated with an anti-slip coating.

[0026] Because the outer surface of the screwing block 15 is coated with an anti-slip coating, the outer surface of the screwing block 15 has a large friction force, which makes it easier for the operator to screw the screwing block 15.

[0027] The rotating rod 5 is made of rubber.

[0028] Because the curved block 6 is made of rubber, it can fit the outer surface of the insulin pen 1 very well, thus ensuring the fixation effect of the curved block 6 on the insulin pen 1 and preventing the curved block 6 from damaging the outer surface of the insulin pen 1.

[0029] Working principle and usage process of this utility model: When the operator needs to disassemble the injection needle 2, the operator first inserts the insulin pen 1 entirely into the housing 3. The insulin pen 1, driven by the injection needle 2, moves forward along the interior of the housing 3, propelling the driven toothed ring 9. Due to the design of the positioning block 8, the insulin pen 1 remains centered within the housing 3. Because of the design of the driven toothed ring 9 and the rotating toothed ring 10, when the housing 3 contacts the hinge block 4 during its forward movement, the housing 3 and hinge block 4 are engaged. At this point, the operator simultaneously wraps their palm around the four rotating rods 5 and presses them inward. The pressure causes the four rotating rods 5 to rotate around the four hinge blocks 4. During this process, the four first springs 7 are compressed. Due to the design of the first springs 7, they will have a good restoring effect on the movement of the rotating rods 5. At the same time, the four arc-shaped blocks 6 will rotate under the drive of the four rotating rods 5. Then, the outer surface of the four arc-shaped blocks 6 will come into contact with the outer surface of the insulin pen 1 during rotation. At this time, the four arc-shaped blocks 6 will squeeze and push the insulin pen 1 to achieve the effect of clamping and fixing the insulin pen 1. After the insulin pen 1 is fixed, the operator can then use their index finger and thumb to... Tightening the screw block 15 causes it to rotate about the engagement point with the fixed ring 16. Since the square rod 14 has a square design, its rotation causes the screw block 15 to rotate, which in turn causes the rotating block 11 to rotate inside the outer casing 3. Simultaneously, the rotating gear ring 10 rotates under the influence of the rotating block 11. Because the outer surface of the rotating gear ring 10 meshes with the outer surface of the driven gear ring 9, the rotating gear ring 10 drives the injection needle 2 to rotate via the driven gear ring 9. The injection needle 2's interior is threaded onto the outer surface of the insulin pen 1. Therefore, when the injection needle 2 rotates along the outer surface of the insulin pen 1, it will move forward simultaneously. During this process, the injection needle 2 will squeeze and push the back of the rotating block 11, causing the rotating block 11 to move forward along the inside of the outer shell 3. During this process, the rotating block 11 will compress the second spring 13 through the ring 12. Due to the design of the second spring 13, it will have a good reset effect on the overall movement of the rotating block 11. Subsequently, the injection needle 2 will separate from the insulin pen 1 during the forward movement, thus realizing the function of making it easy for the operator to disassemble the injection needle 2.
