Disposable anti-needlestick venous blood sampling needle

Abstract

The invention relates to the field of medical instruments, and particularly relates to a disposable anti-needlestick venous blood sampling needle which comprises a blood sampling needle base, a bloodsampling needle tube, a needle sheath, a hose, a hose base and a cork puncture needle, wherein the blood sampling needle tube is mounted on the blood sampling needle base; the needle sheath sleeves the blood sampling needle base; two ends of the hose are respectively connected with the blood sampling needle base and the hose base; the other end of the hose base is connected with the cork punctureneedle; the disposable anti-needlestick venous blood sampling needle further comprises a freely slidable anti-puncture device sleeving the hose and a protection cover connected to the cork puncture needle; the anti-acupuncture device is a hollow tube body; a clamping groove and a track groove are arranged in a tube wall of the anti-needlestick device; and a limiting projection is arranged at a joint of the clamping groove and the track groove. The disposable anti-needlestick venous blood sampling needle provided by the invention can effectively avoid needlestick injuries and eliminate infection of blood-borne diseases, and has advantages of high safety and reliability, simple production process, easy assembly and low production cost.

Description

technical field [0001] The invention relates to the field of medical equipment, in particular to a disposable anti-puncture venous blood collection needle. Background technique [0002] Blood samples are collected to be sent to clinical laboratories for clinical testing. The testing indicators can provide a reliable basis for clinical disease diagnosis, treatment, prevention and prognosis. Clinically, the collection of blood samples is divided into the collection of arterial blood samples and the collection of venous blood samples. The collection of venous blood samples usually adopts the vacuum blood sampling method. [0003] The vacuum blood collection method was first launched by BD in the 1940s with the VACUTAINER vacuum blood collection system. The blood collection technology was further improved in the 1980s. Today, the vacuum blood collection system with a safety head cover is clean, safe, simple, fast, accurate and reliable. , Cost-effective advantages spread all ov...

Problems solved by technology

Although this can effectively protect the needle and prevent the medical staff from being stabbed, it will cause great pain to the patient due to the mechanical action of the needle retraction.

In addition, some blood collection needles use a locked needle tip or other forms of anti-acupuncture structures, but the production process is relatively complicated, assembly is difficult, and production costs are high.
