Product Overview
The venous blood collection needle (also known as the scalp venous blood collection needle) is a common type of venous blood collection needle. Its core feature is that the puncture needle is equipped with "butterfly wing"-shaped handles on both sides, emphasizing operational flexibility and patient adaptability. It is particularly suitable for blood collection scenarios where vascular conditions are complex or patient cooperation is low.
一,Core Components
Venous blood collection needles are typically a combination structure of "needle tube - catheter - blood collection connector", and the key components and their functions are as follows:
• Needle: The front end is a sharp bevel, mostly made of stainless steel to ensure smooth puncture of veins; some models have a silicon coating on the needle tip, which can reduce the pain during puncture.
• Connecting tube: Generally made of medical-grade PVC or PU material, it is used to connect the puncture needle with the blood collection container, preventing blood from being directly exposed during the blood collection process.
Blood collection connector/needle holder: One end is fixed with a puncture needle, and the other end can be connected to a vacuum blood collection tube (blood is automatically drawn through negative pressure) or a syringe. Some connectors are equipped with a hemostatic valve to prevent blood from spilling after the needle is removed.
二, Applicable Scenarios
Compared with straight blood collection needles, the design of double-wing venous blood collection needles makes them more suitable for special populations and complex vascular conditions. They are mainly used for:
For infants and children: Their blood vessels are thin, short and highly mobile. The double-wing handle facilitates precise fixation, and the extended catheter can reduce the interference of children's activities on blood collection.
For elderly patients: Their blood vessels are less elastic and prone to collapse. Using a fine needle body and precise operation can reduce vascular damage and lower the risk of subcutaneous hematoma.
For adults with poor vascular conditions： such as thin veins on the back of the hand or the distal forearm, or those with hardened and scarred veins due to repeated punctures, the double-wing design can increase the success rate of puncture.
For patients with low cooperation：such as those who are agitated, nervous or unable to maintain a fixed position for a long time, the extended catheter can increase the operating distance and reduce the probability of needle displacement during blood collection.
三,. Clinical Application Characteristics
1. Ease of operation: When used with vacuum blood collection tubes, there is no need for manual aspiration. Blood flows into the collection tube automatically under negative pressure, reducing operation steps and improving blood collection efficiency.
2. Sample quality assurance: The dedicated catheters and connectors are made of chemically stable materials that do not react with blood components, thus preventing hemolysis and contamination of the samples and ensuring the accuracy of the test results.
3. Safety: In addition to the anti-stick design of safety lancets, all lancets are single-use sterile products. After use, they should be disposed of in accordance with medical waste regulations to prevent cross-infection.
