Description

Syringe structure

This creation is about an injection syringe structure, especially after the injection is completed, the needle can be hidden in the needle tube to prevent the danger of needle sticks.

According to the general medical injection syringe, it is mainly composed of a syringe, a push rod and a needle. The conventional injection syringe must be set on the syringe before the injection of medicine. Then insert the needle into the medicament bottle, pull the push rod inserted in the syringe, use the needle to attract the medicine into the syringe, then insert the needle into the patient and hold the push rod to hold the needle The medicine in the barrel is squeezed and injected into the patient's body to complete the injection of the medicine. However, the conventional injection syringe is more troublesome in the process of injecting the medicine, and because the needle has a slender needle body, it is easy for medical staff Accidents caused by needle sticks, so most people put a needle cover on the needle to avoid needle stick accidents, but it is often used when the needle is set on the syringe or the needle cover is to be put back on the needle after injection of the medicine. In the process, there is still a risk of being infected by the virus if the needle is accidentally stabbed.

The main purpose of this creation is to provide an injection syringe structure that can effectively solve the lack of an injection syringe after use.

The injection syringe structure of this creation is mainly provided with a needle tube part, the needle tube part is made of bellows shape, the bottom of the needle tube part is provided with a convex body, the top of the convex body is provided with an inlaid edge, and the top of the needle tube part is provided with A fixing flange is provided with a pressing portion extending outward on both sides of the top surface of the needle tube portion, a convex ring and a perforation are provided on the top surface of the needle tube portion, and a fixing seat is set in the fixing flange in the needle tube portion, The fixed seat is provided with a groove, and the inside of the groove is provided with a fixed ring groove for embedding with the embedding edge on the convex body in the needle tube portion, and the bottom edge of the fixed seat is provided with a plurality of grooves connected to the groove Guide groove, a needle is fixed on the fixing seat, the bottom end of the needle is connected to the groove of the fixing seat, the needle extends through the perforation of the top surface of the needle tube, and a cover system is provided On the needle, the cover is embedded in the convex ring of the needle tube.

The advantages of the injection syringe structure of the invention are: after the injection of the medicine is completed, the needle can be hidden in the needle tube, which can prevent the danger of needle sticking and can provide medical personnel with safety in use.

Regarding the technical means used in this creation to achieve the above-mentioned purposes and effects, a preferred and feasible embodiment is presented, as shown in the drawings, and the details are as follows:

In the embodiment of this creation, the injection syringe 1 is mainly provided with a needle tube portion 10, the needle tube portion 10 is set in a bellows shape, the bottom of the needle tube portion 10 is provided with a convex body 11, and the top of the convex body 11 is provided with an insert Edge 110, the top of the needle tube portion 10 is provided with a fixing flange 12, the top surface of the needle tube portion 10 is provided with a pressing portion 13 extending outward on both sides, and the top surface of the needle tube portion 10 is provided with a convex ring 14 and a perforation 15. A fixing seat 2 is set in the fixing flange 12 in the needle tube portion 10. A groove 20 is provided in the fixing seat 2 and the groove 20 is provided with a convex body 11 in the needle tube portion 10 The upper caulking edges 110 are embedded with a fixed ring groove 21, the bottom edge of the fixing seat 2 is provided with a plurality of guide grooves 22 communicating with the groove 20, and a needle 23 is fixed on the fixing seat 2. The bottom end of the needle 23 is connected to the groove 20 of the fixing base 2, the needle 23 penetrates the through hole 15 of the top surface of the needle tube portion 10, and a cover 3 is arranged on the needle 23. The cover The body 3 is embedded in the convex ring 14 of the needle tube portion 10, so that it is an injection syringe structure.

When using this creation, please refer to the third to seventh pictures. After removing the cover 3 from the top surface of the needle tube portion 10, the needle 23 protruding from the needle tube portion 10 is inserted into the patient's body, and the medical staff Only need to support the bottom of the needle tube portion 10 with your thumb, hold the pressing parts 13 on both sides of the top surface of the needle tube part 10 with two fingers (as shown in the third figure), and then press the pressing part 13 and the bottom of the needle tube part 10 , And then squeeze the needle tube part 10, so that the patient can be injected with medicine, and the bellows-shaped needle tube part 10 is compressed, and the medicine A in the needle tube part 10 is squeezed by the guide groove at the bottom of the holder 2 22 and the groove 20 enter the needle 23, and the medicine A can be injected into the patient's body from the tip of the needle 23, and the convex body 11 of the needle tube part 10 is set into the groove 20 of the fixing base 2. The convex body 11 can completely squeeze out the medicine A in the needle tube part 10 (as shown in the fourth and fifth pictures), so that the injection of the medicine A can be completed; and after the medicine A is completely injected (as shown in the fourth picture) , The fixing seat 2 arranged in the top of the needle tube portion 10 moves downward and is sleeved on the convex body 11 in the bottom of the needle tube portion 10, and the inlay 110 on the convex body 11 is embedded in the fixing seat 2 In the ring groove 21, the fixing seat 2 is fixed on the convex body 11 of the needle tube part 10; when the medicine A is injected, only the pressing force on the needle tube part 10 and the pressing part 13 needs to be loosened, and the bellows of the needle tube part 10 The wall surface is elastically restored to its original shape (as shown in Figures 6 and 7), and the needle 23 on the fixed seat 2 is located in the needle tube portion 10, so that the needle 23 is not exposed. In this way, the entire injection of the medicine A can be completed. This creation can hide the needle 23 after the injection is completed in the needle tube portion 10, which can prevent the danger of being punctured by the needle, and can indeed achieve the safety of use.

In summary, this creation has indeed achieved the intended purpose and effect of use, and is more ideal and practical than the conventional ones. However, the above embodiments are only specific descriptions of the preferred embodiments of this creation. This embodiment is not intended to limit the scope of patent application of this creation. All other equal changes and modifications completed without departing from the technical means disclosed in this creation should be included in the scope of patent application covered by this creation.
