Specific implementation manners

[0032] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0033] Refer to Figure 2 , Figure 3 and Figure 6, an embodiment provided by the present utility model: a special syringe for treating diabetes in combination with cell technology, comprising a syringe barrel 1 and a fixed shell 3. One end of the syringe barrel 1 is provided with a fixed groove 9. One end of the syringe barrel 1 is fixedly connected with two fixing plates 10. The outside of the fixing plate 10 is fixedly connected with a first spring 11. The other end of the first spring 11 is fixedly connected with a button 5. One end of the syringe barrel 1 is fixedly connected with a second needle 13. The outside of the second needle 13 is provided with a sealing groove 14. One end of the fixed shell 3 is fixedly connected with a first needle 4. A filtering member 16 is arranged inside the first needle 4. A sealing gasket 17 is fixedly connected to the inner wall of the first needle 4. The other end of the fixed shell 3 is fixedly connected with a fixing ring 12. Two installation grooves 15 are arranged on the outside of the fixed shell 3. The inner wall of the syringe barrel 1 is slidably connected with a piston 21. One end of the piston 21 is fixedly connected with a push rod 2. The fixing ring 12 is inserted and matched with the fixed groove 9. The two buttons 5 are inserted and matched with the corresponding installation grooves 15. The inner wall of the first needle 4 is slidably connected to the outside of the second needle 13. The sealing gasket 17 is inserted and matched with the sealing groove 14. One end of the push rod 2 is provided with an anti-slip pattern 20.

[0034] Specifically, the syringe barrel 1 serves as the main liquid storage and delivery container. The fixed groove 9 opened in the syringe barrel 1 is for stable connection with the fixed shell 3. The two fixing plates 10 provide connection points for the two first springs, making the first springs more stable during use. The other end of the first spring 11 is connected to the button 5, enabling the button 5 to move flexibly. The sealing groove 14 ensures the sealing performance when connecting with the first needle 4 and the second needle. The filtering member 16 can filter out the glass debris in the liquid medicine inside the ampoule bottle to ensure the purity of the liquid medicine. When the first needle 4 is connected to the second needle 13, the sealing gasket 17 can tightly fit into the sealing groove 14 to form a reliable seal. The fixing ring 12 fits perfectly with the fixed groove 9 of the syringe barrel 1, ensuring the stable connection between the syringe barrel 1 and the fixed shell 3. The two installation grooves 15 correspond to the buttons 5, ensuring more stable connection between the fixed shell 3 and the syringe barrel 1. The sliding of the piston 21 can precisely control the delivery volume of the liquid medicine. The movement of the piston 21 is driven by operating the push rod 2. The anti-slip pattern 20 ensures that the push rod 2 can be stably held.

[0035] Refer to Figure 2 and Figure 5 , one end of the fixed shell 3 is provided with an auxiliary component for assisting the syringe barrel 1. The auxiliary component includes two mounting shells 6. The outside of the two mounting shells 6 is fixedly connected to one end of the fixed shell 3. A spring plate 18 is slidably connected to the inner wall of the mounting shell 6. One end of the spring plate 18 is fixedly connected with a second spring 19. The other end of the spring plate 18 is fixedly connected with a connecting rod 7. The other end of the second spring 19 is fixedly connected to the inner wall of the mounting shell 6. The other end of the connecting rod 7 is fixedly connected with a rubber block 8.

[0036] Specifically, during injection, the first needle 4 is inserted into the patient's skin. At this time, the rubber block 8 in the auxiliary component will adhere to the patient's skin, forming a soft contact surface. As the rubber block 8 presses tightly against the skin, the connecting rod 7 will be pushed inward under the action of the second spring 19, generating a certain pressing force. This pressing force can disperse the pressure during injection, helping to reduce the pain and discomfort of the patient during injection. Then, hold the part of the push rod 2 with anti-slip lines 20 and push forward. The movement of the push rod 2 will drive the piston 21 to move forward, thereby pushing the liquid medicine out of the first needle 4 and into the patient's body. The entire injection process is precise and stable, ensuring the accurate delivery of the liquid medicine and the comfortable experience of the patient.

[0037] Working principle: When connecting the first needle 4 and the second needle 13, first press the two buttons 5 to squeeze the corresponding springs 11, then insert the fixing ring 12 at one end of the fixing shell 3 into the fixing groove 9 at one end of the syringe barrel 1, and then release the buttons 5. Under the elastic action of the springs 11, the buttons 5 will be snapped into the corresponding mounting grooves 15 to ensure the stable connection between the syringe barrel 1 and the fixing shell 3. During this process, the inner wall of the first needle 4 will slide along the outside of the second needle 13, and the sealing gasket 17 will snap into the inner wall of the sealing groove 14 to form a seal. When sucking the liquid medicine inside the ampoule bottle, the filter element 16 filters the glass debris in the liquid medicine to prevent the medicine residue from entering the inside of the syringe barrel 1.

[0038] When injecting, insert the first needle 4 into the patient's skin. The rubber block 8 will adhere to the patient's skin and drive the second spring 19 to be squeezed inward under the action of the connecting rod 7, generating a certain pressing force. This pressing force helps to reduce the pain and discomfort of the patient during injection. Hold the part of the anti-slip lines 20 on the push rod 2 and push forward. The piston 21 moves forward under the action of the push rod 2, pushing the liquid medicine out of the first needle 4 and into the patient's body.

[0039] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Although the present invention has been described in detail with reference to the foregoing embodiments, for those skilled in the art, they can still modify the technical solutions recorded in the foregoing embodiments, or perform equivalent replacements for some of the technical features. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present invention shall be included in the protection scope of the present invention.
