Safety blood collection needles are single-use medical devices, primarily available in two types: press-type and locking-type (such as the BA type). They consist of an intravenous puncture needle, transfusion tubing, sampling needle, and protective sheath. Utilizing core-locking technology, they ensure single-use safety. After blood collection, a spring-triggered automatic retraction mechanism retracts the needle into the outer tubing, eliminating the risk of needlestick injury.
The product comes in individually sterile packaging. After use, residual blood is prevented from dripping due to negative pressure. With proper operation, medical institutions can effectively reduce the risk of bloodborne infections such as HIV and hepatitis. This device is suitable for blood glucose testing and diabetes diagnosis, offering multiple needle sizes and puncture depth configurations. The core structure includes an outer tubing, an inner tubing, and a spring assembly, with mechanical linkage ensuring safe needle retrieval.
