Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of anti-needle puncture vein steel needles, in particular to an anti-needle puncture vein steel needle. Background Art
[0002] In recent years, infusion nursing is an important and commonly used nursing operation in clinical nursing. About 90% of hospitalized patients in my country need infusion treatment, and about 30% of patients in outpatient and emergency departments also need infusion treatment. Intravenous infusion occupies about 80% of nurses' working time. At present, disposable steel needles are widely used in outpatient and emergency intravenous infusion and venous blood collection in my country. However, a large number of domestic studies have shown that nurses are a high-risk occupational group for blood-borne diseases. Wounds caused by cuts and needle punctures are often seen on nurses' hands. At present, nurses in most hospitals in my country use disposable intravenous infusion steel needles for peripheral vein puncture. When nurses remove intravenous infusion steel needles or handle discarded scalp needles, the steel needles may puncture their fingers and cause blood infection. When medical staff remove or clean discarded needles, they are easily stabbed by needles and easily infected with diseases. At the same time, discarded needles exposed in the environment are prone to environmental pollution, which poses serious safety hazards. Infection incidents can cause great psychological trauma and physical harm to infected persons. In order to avoid infection caused by stabbing of medical staff and reduce the probability of stabbing incidents, the existing intravenous infusion needles are retracted after use.
[0003] Studies have shown that nurses are a high-risk occupational group for blood-borne diseases. In order to prevent nurses from the risk of needle stick infection during venipuncture, there are currently anti-needle stick infusion needles that use a telescopic design to pull out the needle and rebound the needle head, and use stainless steel springs, clips, etc. to wrap the needle tail to reduce the risk of needle stick injuries. Utility Model Content

[0006] The anti-needlestick assembly includes a needle blocker located at one end of the infusion tube, a catheter seat slidably arranged inside the needle tube, a spring groove arranged on the catheter seat along the length direction of the needle tube, a rebound spring arranged in the spring groove, a blocking member arranged at one end of the rebound spring, and a button arranged on the side wall of the needle tube and perpendicular to the rebound spring; a limiting portion abutting against one end of the button is arranged on the side of the blocking member, and a card slot adapted to the limiting portion is arranged on the side wall of the needle tube.
[0007] Preferably, a cavity is provided inside the needle tube.
