Safety syringe needle

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....

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 manufacturers such as BD, syringes are only one of their products. BD’s revenue in 2001 was 3.754 billion US dollars. The company is divided into three major departments: Medical system, Clinical lab, and Bioscience. There are so many, big factories are not in a hurry to intervene, and small factories have room to survive

[0016] Although safety syringes and self-destructing syringes have advantages in use, the high price also prevents their promotion
