[0001] This utility model relates to the field of medical device technology, specifically to a Bilan anesthetic syringe. Background Technology

[0002] A syringe is a common medical device, mainly used to draw or inject gas or liquid with a needle. Bilan syringes are mainly used for local anesthesia during treatment to reduce pain for patients and facilitate treatment.

[0003] When using the existing Bilan anesthetic syringe, if the user needs to change the injection needle, turning the injection needle will cause the screw connector to come off. Therefore, the screw connector needs to be removed and reinstalled manually, which may cause injury to medical staff. Summary of the Invention

[0004] Therefore, this utility model provides a Bilan anesthetic injector, in which the user uses a positioning mechanism to position and connect the connector to the injector body. When the user twists the needle, the positioning mechanism will fix the connector to prevent it from loosening, thus solving the problem that when the user needs to replace the injection needle in the existing Bilan anesthetic injector, twisting the injection needle will cause the screw connector to fall off.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a Bilan anesthetic syringe, comprising a syringe body, wherein a piston head is provided inside the syringe body, a piston rod is fixedly connected to one end of the piston head, and one end of the piston rod extends to the outer side of the top of the syringe body;

[0028] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0029] See attached document Figure 1 -Appendix Figure 5 The present invention provides a lan anesthetic syringe, including a syringe body 1, a piston head 2 inside the syringe body 1, a piston rod 3 fixedly connected to one end of the piston head 2, and one end of the piston rod 3 extending to the outer side of the top of the syringe body 1.

[0030] A connecting ring 4 is fitted on the outer side of the syringe body 1, and two auxiliary handles 5 are provided on the outer side of the connecting ring 4;

[0031] The syringe body 1 has a connector 6 at the bottom end, which is connected to the syringe body 1 by a thread, and a positioning mechanism is provided on the outside of the connector 6.

[0032] Needle 7 is sleeved on the outside of connector 6, and needle 7 is connected to connector 6 by threads;

[0033] In this embodiment, the user uses the positioning mechanism to position and connect the connector 6 and the syringe body 1. When the user twists the needle 7, the positioning mechanism will fix the connector 6 to prevent it from loosening.

[0034] To achieve the positioning of the connector 6, the device employs the following technical solution: The positioning mechanism includes a positioning ring 8, which is sleeved on the outside of the connector 6 and slides with the connector 6. Two limiting rods 9 are embedded on the outside of the connector 6, and both limiting rods 9 slide with the connector 6. Both limiting rods 9 are fixedly embedded inside the positioning ring 8. The positioning mechanism also includes two movable grooves 10, which are opened on the outside of the bottom of the syringe body 1. The two movable grooves 10 are respectively matched with the two limiting rods 9. Two positioning grooves 11 are opened inside each of the two movable grooves 10. Positioning rods 12 are embedded inside each of the two limiting rods 9 and are respectively matched with the two positioning grooves 11. A circular plate 13 is fixedly connected to the outer end of each of the two positioning rods 12. A pull rope 14 is fixedly connected to the outer side of each of the two circular plates 13. A lever 15 is fixedly connected to the outer end of each of the two pull ropes 14. A spring 17 is sleeved on the outer side of each of the two positioning rods 12 and is fixedly connected to the bottom of each of the two circular plates 13.

[0035] When the user needs to replace the needle 7, the connector 6 is fixed by the positioning mechanism so that the needle 7 will not rotate and the connector 6 will not rotate. Similarly, when the user needs to remove the connector 6, the user moves the two levers 15 to the middle. The movement of the two levers 15 causes the two pull ropes 14 to tighten. The tightening of the two pull ropes 14 causes the positioning rod 12 to move up and lift, so that the positioning rod 12 is disengaged from the outside of the positioning groove 11. Then, the user pulls the positioning ring 8 down, so that the limiting rod 9 falls out of the limiting groove, making it easy for the user to twist and remove the connector 6.

[0036] In order to achieve the purpose of limiting, the device adopts the following technical solution: multiple auxiliary frames 16 are fixedly connected to the outside of the positioning ring 8, the multiple auxiliary frames 16 are respectively sleeved on the outside of the two pull ropes 14, multiple support plates 18 are fixedly connected to the outside of the positioning ring 8, and positioning wheels 19 are provided between the multiple support plates 18, and the two positioning wheels 19 are respectively located inside the two pull ropes 14.

[0037] The design of the auxiliary frame 16 and the positioning wheel 19 allows the pull rope 14 to extend and retract stably, preventing the pull rope 14 from deviating.

[0038] The usage process of this utility model is as follows: The user positions the connector 6 and the syringe body 1 using the positioning mechanism. When the user twists the needle 7, the positioning mechanism fixes the connector 6 to prevent it from loosening. When the user needs to replace the needle 7, the connector 6 is fixed by the positioning mechanism so that the needle 7 will not rotate and the connector 6 will not rotate. Similarly, when the user needs to remove the connector 6, the user moves the two levers 15 to the middle. The movement of the two levers 15 causes the two pull ropes 14 to tighten. The tightening of the two pull ropes 14 causes the positioning rod 12 to move upward and lift, so that the positioning rod 12 is disengaged from the outside of the positioning groove 11. Then, the positioning ring 8 is pulled downward, so that the limiting rod 9 falls out of the limiting groove, making it easy for the user to twist and remove the connector 6. The design of the auxiliary frame 16 and the positioning wheel 19 allows the pull rope 14 to extend and retract stably, preventing the pull rope 14 from shifting.

[0039] The above description is merely a preferred embodiment of this utility model. Any person skilled in the art may modify this utility model or modify it into an equivalent technical solution using the technical solutions described above. Therefore, any simple modifications or equivalent substitutions made based on the technical solutions of this utility model are within the scope of protection claimed by this utility model.
