The invention discloses a pressing-type safety protection mechanism of a blood taking needle, which comprises a sleeve part and a valve core part, and the valve core part is provided with three parts,namely a needle seat part, a sleeving part and a stopping part; a plurality of limiting grooves are formed in the stopping part; the sleeve part is provided with two parts, namely a first sleeve partpositioned at a front section and a second sleeve part positioned at a rear section; an elastic button higher than the side wall of the first sleeve part is arranged on the side wall of the valve core part; a limiting opening matched with the elastic button is formed in the side wall of the first sleeve part; a limiting sliding cavity for containing the elastic button and the valve core piece isformed in the inner side from the first sleeve part to the second sleeve part from the limiting opening, and the limiting sliding cavity guides and limits front-back movement of the elastic button andthe valve core piece, a plurality of elastic limiting convex pieces matched with the limiting grooves are arranged on the inner wall of the tail sliding cavity of the second sleeve part. Through thedesign of the elastic button, a medical worker can operate by one hand with the left hand and the right hand during use.
Description
technical field [0001] The invention relates to a press-type safety protection mechanism for a blood collection needle, which belongs to the technical field of medical safety. Background technique [0002] In clinical work, the occurrence of injection-related needlestick injuries is random and uncontrollable, and nursing staff is a high-risk group for needlestick injuries. The harms of unsafe injections to society include needle sticks after use and improper disposal of injection equipment after use, leading to the spread of infection in society. Standard prevention was proposed by the Centers for Disease Control and Prevention in the United States in 1995 and implemented in the United States in 1996. It was introduced in my country in 1999 and incorporated into the "Nosocomial Infection Management Standards (Trial)" issued by the Ministry of Health in 2000. The standard precautionary point of view is that: all patients' blood, body fluids, excreta, and secretions are infec...
