Description

Syringe

The present invention relates to an injection syringe, in particular to an integrated needle, needle tube and medicament, which can hide the needle and prevent the risk of being punctured by the needle.

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 assembled on the syringe before the injection of medicine. Then insert the needle into the medicine 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 press the push rod to hold the needle The medicament in the barrel is squeezed and injected into the patient’s body to complete the injection of the medicament. However, the conventional injection syringe is more troublesome in the process of injecting the medicament, and because the needle has a slender needle body, it is in use. Medical staff are prone to accidents caused by needle sticks, so most people put a needle cover on the needle to avoid needle stick accidents. However, it is often because the needle cover is about to be put back on the needle after the injection of the medicine. Accidentally being pierced by the injection needle may lead to the risk of viral infection, and the use of conventional injection syringes and needle covers, etc., has caused a large amount of medical waste to be generated, and the cost of medical waste treatment is extremely large.

The main purpose of the present invention is to provide an injection syringe, which can effectively solve the lack of the injection syringe during use.

The injection syringe of the present invention is mainly provided with a needle tube part, a compression part is arranged above the needle tube part, a positioning plate is arranged between the needle tube part and the compression part, the positioning plate is provided with a perforation, and the positioning plate is outside A positioning block is arranged on the wall surface, a pressing part is arranged above the compression part, the middle part of the pressing part is set as a piercing surface, two sides of the pressing part are extended with a buckle piece, and the bottom surface of the buckle piece is provided with a supply The locating block of the locating plate is provided with a hook for locking each other, the bottom of the needle tube portion is provided with a fixing seat, the bottom of the fixing seat is provided with a plurality of communicating guide grooves, and a needle is fixed on the fixing seat, The needle is penetrated into the compression part through the perforation of the positioning plate, and the needle tip of the needle is located below the piercing surface of the pressing part.

In the injection syringe of the present invention, the needle tube part is made of a bellows shape.

In the injection syringe of the present invention, the compression part is a cone-shaped bellows shape.

In the injection syringe of the present invention, a drug is injected into the needle tube portion.

The injection syringe of the present invention has the advantages that: the needle, the needle tube and the medicine are integrated, which can provide the safety of the medical staff in the use of the injection syringe, and the needle can be retracted and hidden in the injection without the need for a needle cover. The inside of the syringe can prevent the danger of being punctured by needles, make the injection of medicine more convenient, and can reduce the amount of medical waste generated, and can reduce the cost of medical waste treatment.

Regarding the technical means adopted by the present invention in order to achieve the above-mentioned use purposes and effects, a preferred and feasible embodiment is presented and shown in conjunction with the drawings. The details are as follows:

For the embodiment of the present invention, please refer to the first and second figures. The injection syringe 1 is mainly provided with a needle tube portion 10, the needle tube portion 10 is configured as a bellows shape, and the needle tube portion 10 is provided with a compression portion 11 above. The compression part 11 is made of a cone-shaped accordion shape. A positioning plate 12 is provided between the needle tube part 10 and the compression part 11. The positioning plate 12 is provided with a perforation 120, and the positioning plate 12 is provided on the outer side wall surface The positioning block 121 is provided with a pressing part 13 above the compression part 11, the middle part of the pressing part 13 is set as a piercing surface 130, and two sides of the pressing part 13 are extended with a buckle piece 131, the bottom surface of the buckle piece 131 A hook 132 for interlocking with the positioning block 121 of the positioning plate 12 is provided. The bottom of the needle tube portion 10 is provided with a fixing seat 14, and the bottom of the fixing seat 14 is provided with a plurality of communicating guide grooves 140, A needle 15 is fixed on the fixing seat 14. The needle 15 is penetrated into the compression portion 11 through the through hole 120 of the positioning plate 12, and the needle tip 150 of the needle 15 is located on the piercing surface 130 of the pressing portion 13 Below, the needle tube portion 10 is filled with the medicine A, so that it is an injection syringe structure.

When the present invention is used, please refer to the third to seventh figures. The medical staff only needs to support the bottom of the needle tube with their thumbs, and hold the two fingers on the buckle piece 131 of the pressing part 13 (as shown in the third figure) ), press the retaining piece 131 and the bottom of the needle tube portion 10, so that the pressing portion 13 presses the compression portion 11 and moves toward the positioning plate 12, and the needle tip 150 of the needle 15 located in the compression portion 11 presses the puncture surface of the compression portion 13 130 is pierced and extended. At the same time, the cone-shaped bellows-shaped compression part 11 is compressed by the pressing part 13 to be compressed into a folded state, and the positioning block 121 of the positioning plate 12 is clamped on the buckle piece 131 In the hook 132 at the bottom, the pressing part 13 is positioned on the positioning plate 12 without loosening (as shown in the fourth and fifth figures), so that the patient can be injected with medicine, and the pressing part 13 will be protruded After the needle 15 on the puncture surface 130 is inserted into the patient’s body, the needle tube part 10 is pressed against the pressing part 13, the bellows-shaped needle tube part 10 is compressed, and the medicine A in the needle tube part 10 is fixed by The guide groove 140 of the seat 14 is squeezed into the needle 15 (as shown in Figures 6 and 7), and the medicine A can be injected into the patient's body from the needle 150. In this way, the injection of medicine A can be completed; After the injection of the medicine A, only need to loosen the pressing force of the syringe part 10 and the pressing part 13, the bellows-shaped wall surface of the syringe part 10 will elastically return to its original shape (as shown in the fourth figure), and then the pressing part 13 The hook 132 and the positioning block 121 of the positioning plate 12 are unlocked, and the conical bellows-shaped compression part 11 also elastically returns to push the pressing part 13 upward and back to the original position, and the compression part 11 and the pressing part 13 are again The needle 15 is shielded so that the needle 15 is not exposed, so that the entire injection of the medicine can be completed; the present invention sets the needle, the needle tube and the medicine as an integrated type, which can hide the needle 15 inside the injection syringe 1 to prevent being The danger of needle sticks can indeed achieve the safety of the use of injection syringes, and there is no need to set up additional needle covers, which can reduce the generation of medical waste and the cost of treatment, and can simplify the operation procedures of injecting drugs, so that the injection of drugs More convenient.

In summary, the present invention has indeed achieved the intended purpose and effect of use, and is more ideal and practical than the conventional ones.
