Double wing blood collection needle, also known as butterfly wing blood collection needle, is a widely used blood collection tool in medical institutions, especially suitable for collecting peripheral blood from the human body. The following is a detailed introduction to the biplane blood collection needle product:

Product composition
The double wing blood collection needle is mainly composed of plastic sheath, bottle stopper puncture needle, needle seat, hose, needle handle, venipuncture needle and venipuncture needle protective cover and other components. These components work together to ensure the smooth progress of the blood collection process.

Product Features

Bidirectional design: The biplane blood collection needle adopts a bidirectional design, with one end inserted into the human vein and the other end inserted into the vacuum blood collection tube. Through negative pressure suction, blood is directly drawn from the blood vessel into the test tube without the need for secondary transfer, reducing the risk of contamination.

Sharp needle tip: The needle tip of the blood collection needle is sharp and free of burrs, ensuring a smooth and easy puncture process and reducing patient pain.

Soft extension tube: equipped with a soft extension tube, far away from the puncture point, easy to replace the test tube operation, while reducing blood leakage.

Closed elastic protective cover: One end of the test tube is equipped with a closed elastic protective cover, which effectively prevents blood leakage and reduces the risk of blood borne infections.

Easy to control blood collection volume: Through the principle of negative pressure suction, when a certain pressure balance is reached in the test tube, the blood flow automatically stops, and the amount of blood collected is easy to control, generally meeting various clinical examination needs.

Scope of application
The double wing blood collection needle is suitable for patients of different age groups and for blood collection needs in different parts. Its smooth and easy puncture experience and sensitive blood return response ensure a success rate of hitting the nail on the head, reducing patient pain and nurse workload.

Precautions for use

Pre use inspection: Before use, please carefully check whether the needle tip of the venipuncture needle has defects such as hooks, burrs, deformation, etc. If there are any, it should not be used.
Matching use: The biplane blood collection needle should be used in conjunction with the vacuum blood collection tube to ensure a smooth blood collection process.
Aseptic operation: During the blood collection process, strict adherence to aseptic operation standards should be followed to avoid cross infection.
