As some domestic enterprises focus on the research and production of blood collection system, their products and imported products have tended to be homogenized, these enterprises can provide users with good technical services and quality assurance. For example, while producing vacuum blood collection tubes, Chengdu Ruiqi Company is also researching and producing blood collection needles, including needle holders.
A good blood collection needle must have the following advantages:
1. The cutting edge, length and angle of the needle are suitable for venipuncture. The cutting edge is extremely smooth, and the patient had less discomfort and residual pain after sampling.
2. The inner wall of the needle tube is very smooth, which improves the speed of blood collection and avoid fragile blood cells from being adsorbed or destroyed during rapid passage, reducing blood cell damage. The ultra-thin needle tube wall can minimize the tissue trauma caused by puncture, reduce the infiltration of tissue fluid, and improve the quality of specimens.
3. The rubber sleeve of the two-way needle and the soft needle near the side of the sampler vessel can withstand 100 times of penetration without liquid leakage, which can realize the collection of multiple tube specimens for one venipuncture, so as to ensure the safety of venipuncture on the premise of reducing the pain of patients and the workload of medical personnel.
