I、 Advantages of venous blood collection needle products

1. The cutting edge, length and angle of the needle are suitable for venipuncture. The cutting edge is very smooth, and the patient's discomfort and residual pain after sampling are mild.

2. The inner wall of the needle tube is very smooth, so as to improve the blood collection speed and avoid the fragile blood cells from being adsorbed or damaged during rapid passage, so as to reduce the damage of blood cells. Ultra thin needle wall can greatly reduce the tissue trauma caused by puncture, reduce the infiltration of tissue fluid and improve the quality of specimens.

3. The rubber sleeve on the side of the two-way needle and soft needle close to the collecting vessel can withstand 100 penetrations without liquid leakage. It can realize one-time venipuncture to collect multi tube specimens, and ensure the safety of venipuncture on the premise of reducing the pain of patients and the workload of medical personnel.
