Butterfly Type Venous Blood Specimen Collection Needle

The butterfly type venous blood specimen collection needle features a winged design for improved stability and control during blood sampling, making it ideal for accessing small or difficult veins.

 

 

Main Components:

1. Needle: Made of fine, stainless steel, the needle is designed for piercing veins with a sharp tip, minimizing tissue damage.

2. Wings: The plastic wings on both sides provide better grip and stability during the insertion process, allowing for improved control and reduced discomfort.

3. Flexible Tubing: A flexible tube extends from the needle, providing a manageable length that allows for easy maneuvering without causing twisting or pulling during blood collection.

4. Vacuum Collection System: Generally used in conjunction with vacuum collection tubes, which automatically draw blood, ensuring sample quality and preventing contamination.

5.Safety Mechanism: Many modern butterfly needles come equipped with a safety feature that automatically covers the needle after use, reducing the risk of accidental needlestick injuries.

Suitable Scenarios:

◆ Children or Infants: The needle is particularly suitable for small veins, making it ideal for this patient group.

◆ Elderly Patients: As veins can be fragile, using a butterfly needle reduces difficulty and discomfort during blood collection.

◆ Patients with Difficult Veins: In some cases, butterfly needles make it easier to locate suitable veins for blood sampling.

Collection Process

◆ Preparation: The nurse or doctor will clean their hands and the collection site, choose a suitable vein, and prepare the necessary equipment.

◆ Insertion: The needle is inserted at a 15 to 30-degree angle into the vein, watching for a return of blood to confirm placement.

◆ Sample Collection: A vacuum tube is connected to the flexible tubing, allowing blood to automatically fill the tube.

◆ Completion: After sampling, the needle is quickly withdrawn, and a cotton ball is pressed against the site to stop bleeding, ensuring patient safety.

Precautions

◆ Maintain a sterile technique during the procedure to avoid infection.

◆ Choose the appropriate needle size based on the patient's condition, typically using 21G or 23G.

◆ If difficulties arise, adjust or change the vein location promptly to avoid causing discomfort to the patient.
