Problems solved by technology

[0015] In addition, traditional syringe manufacturers have not fully developed safety syringes, which is related to the market size. The annual demand for traditional syringes is 30 billion, and each one is calculated at 0.1 US dollars, which is equivalent to a market value of 3 billion US dollars, while the safety syringe market in the United States is about 700 million. The dollar is relatively small, and for major international manufactu

Example Embodiment

[0031] In order to make it easy to understand the technical means, creative features, objectives and effects achieved by the present invention, the implementation of the present invention will be further described below in conjunction with specific drawings.

[0032] See figure 1 , figure 1 A schematic diagram of the assembly of the safety injection needle of the present invention before being used is given. The safety injection needle includes a needle tip 100, a needle seat 200, a needle tip protective sheath 300, a spring 400 and a sheath 500. The needle hub 200 has an interface part connected with the syringe 600, and the interface part is a Luer interface 210. When in use, the luer connector 210 of the needle holder 200 can be inserted into the luer connector 610 of the syringe 600.

[0033] The needle tip 100 of the safety injection needle of the present invention is fixed on the needle seat 200. The needle tip protective sleeve 300 is a cylindrical structure. When not in...

Abstract

A safety syringe needle comprises a needle, a needle holder, a needle protective cover, a spring, and a locking-releasing structure, wherein the needle protective cover, which is sleeved on the needle holder before and during injection, is moved to the needle after injection and protects the needle, the spring disposed between the needle holder and the needle protective cover is used for driving the needle protective cover to move from the needle holder to the needle after injection, and the locking-releasing structure disposed between the needle holder and the needle protective cover is used for locking the needle protective cover at the needle holder before and during injection and releasing the needle protective cover after injection. When located at the needle holder, the needle protective cover compresses the spring on the needle holder; and when the needle protective cover is located at the needle, the spring is released. The safety syringe needle prevents medical staff from being accidentally punched by the needle during use, prevents reusing of a syringe/needle, and has the advantages of disposability, safety, sanitation, convenience in use, and easiness in recycling.

Description

technical field [0001] The invention relates to a novel injection needle, in particular to a safety injection needle with a needle point protection function. This safety needle can be used with standard ordinary syringes. When the safety device is activated after use, the needle tip can be shielded, thereby achieving the effect of preventing needle stick injury. Background technique [0002] Currently, there is a risk for doctors or nurses to be pricked by the injection needle on the syringe after the injection is completed or the blood sample is drawn from the patient. In foreign countries, this phenomenon is called "sticky needles". As a result, medical staff and those who handle these medical wastes are often exposed to the risk of infection with blood-related diseases, such as AIDS (HIV), hepatitis B (HBV), hepatitis C (HCV), etc. [0003] According to the report of the World Health Organization, as many as 8 to 16 million people are infected with hepatitis B, 2 to 4....
