Description

Syringe

The invention relates to an injection syringe, in particular to an integrated needle, needle tube and medicine, which can hide the needle and prevent the needle from being stuck.

According to the general medical injection syringe, it is mainly composed of a syringe, a push rod and a needle, and the conventional injection syringe must be set on the syringe before the injection of medicine. Then insert the needle into the medicine bottle, draw the push rod inserted into the syringe, use the needle to attract the medicine into the syringe, insert the needle into the patient and press the push rod to insert 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 operation process of injecting the medicine, and because the needle has an elongated needle body, it is in use , Medical staff are prone to accidents caused by needle stick injuries, so most of the time a needle cover is set on the needle to avoid the accident of needle stick, but often because after the injection of the drug, the needle cover wants to be put back on the needle, there are still Accidentally being injured by an injection needle may cause a risk of virus infection, and the use of conventional injection syringes and needle covers, etc., causes a large amount of medical waste to be generated, and the treatment cost of medical waste is extremely huge.

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 convex body is provided at the bottom of the needle tube part, a compression part is provided above the needle tube part, a positioning plate is arranged between the needle tube part and the compression part, and the positioning plate A perforation is provided on the bottom of the positioning plate. A fixing seat is provided at the bottom of the positioning plate. A groove is provided in the fixing seat. The convex system of the needle tube portion corresponds to the groove of the fixing seat. In the guiding groove of the groove, a positioning block is provided on the outer side wall surface of the positioning plate, a pressing part is provided above the compression part, a middle part of the pressing part is set as a puncture surface, and two sides of the pressing part are extended A buckle piece, the bottom surface of the buckle piece is provided with a hook for interlocking with the positioning block of the positioning plate, a needle is fixed on the perforation of the positioning plate, and the bottom end of the needle is connected to In the groove of the fixing seat, the needle is located in the compression part, and the needle tip of the needle is located below the puncture surface of the pressing part.

In the injection syringe of the present invention, the needle tube is of a bellows type.

In the injection syringe of the present invention, the compression portion is a cone-shaped snake belly.

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

The advantages of the injection syringe of the present invention are: the needle, the syringe and the medicine are integrated, which can provide the safety of the medical staff when using the injection syringe, and the needle can be retracted and hidden from the injection without the need of a needle cover Inside the syringe, the danger of being stuck by the needle can be prevented, the injection of medicine can be more convenient, the amount of medical waste can be reduced, and the treatment cost of medical waste can be reduced.

The technical means adopted by the present invention in order to achieve the above-mentioned use purpose and effect, hereby cite preferred and feasible embodiments, and in conjunction with the drawings, the details are as follows:
