Safety syringe structure and manufacturing method thereof

Abstract

The invention discloses a safety syringe structure comprising a syringe, a push rod arranged inside the syringe and a syringe needle group connected with the push rod, wherein a syringe needle of the syringe needle group extends out of the syringe, and a cover is sleeved on the syringe needle. The safety syringe structure is characterized in that the push rod comprises a rod body, a butt joint seat is arranged at the top of the rod body, a butt joint hole is disposed on the butt joint seat and connected with the bottom of a metal hook body; the syringe needle group comprises a syringe needle seat and a syringe needle connected with the syringe needle seat, and a lock groove is arranged at the bottom of the syringe needle. When in use, the cover of the safety syringe needle is taken down for normal injection, and when the injection is finished, the metal hook body is inserted into the lock groove and positioned, and the push rod is pulled out outwards, and thereby the syringe needle is driven into the syringe, and the push rod is snapped. Accordingly, the syringe needle is arranged in the syringe, a user is not prone to be stabbed and infected. The invention has the advantages of safety, sanitation, high working efficiency and low manufacturing cost.

Description

Technical field: [0001] The invention relates to the field of medical devices, in particular to a safety syringe structure and a manufacturing method thereof. Background technique: [0002] In the field of medical science and technology today, disposable syringes (or disposable syringes) are commonly used. The syringes are mainly composed of a syringe, a push rod and a needle seat. When used for medical injection, the push rod can be used to Directly push the liquid medicine stored inside the syringe, and inject it out from the needle sleeved at the end of the syringe, but because the injected needle will be exposed after touching the disease body (such as the user's body part), so When the injection of the syringe is completed, the medical staff or health workers must manually cover the needle holder with the needle cover and recover it. At this time, if there is a slight carelessness or negligence, it is very likely to be accidentally stabbed by the needle. Increased the ...

Problems solved by technology

[0002] In the field of medical science and technology today, disposable syringes (or disposable syringes) are commonly used. The syringes are mainly composed of a syringe, a push rod and a needle seat. When used for medical injection, the push rod can be used to Directly push the liquid medicine stored inside the syringe, and inject it out from the needle sleeved at the end of the syringe, but because the injected needle will be exposed after touching the disease body (such as the user's body part), so When the injection of the syringe is completed, the medical staff or health workers must manually cover the needle holder with the needle cover and recover it. At this time, if there is a slight carelessness or negligence, it is very likely to be accidentally stabbed by the needle. Increased the possibility of blood-borne diseases, whether from patients, doctors, nurses, caregivers to health workers, all those who come into contact with syringes in the working environment are potential risk groups. Therefore, in order to reduce the use of syringes Many medical equipment manufacturers are committed to developing safe syringes that do not need to be recycled by hand, so that medical staff can relatively reduce the chance of being infected, such as AIDS, syphilis, hepatitis B, hepatitis C, tuberculosis, diphtheria, typhoid fever blood-borne diseases

[0003] In the processing of the plunger of the syringe barrel, most of the processing procedures are performed manually, and the operation is time-consuming and laborious, and the production speed is slow, which will not only increase the trouble in assembly, but also relatively increase the use of materials and The cost of manufacturing and testing quality control makes it relatively high whether it is the cost of manual configuration or the cost of production and manufacturing, which is not in line with the consideration of economic benefits. In addition, manual operations will also cause The defect and defect rate of the product cannot be effectively reduced, and because of the cumbersome assembly process, the possibility of component contamination is greatly increased, and it is difficult to ensure a certain quality

[0004] Therefore, there are still many defects in the use of the above-mentioned syringe, and there is room for further improvement.
