Multi-Sample Blood Collection Needles (Pen Needles)
View Details
Product Overview
Manufactured in ISO 13485-compliant facilities, XINLE Veterinary Butterfly Blood Collection Needles provide veterinary surgeons and technicians with enhanced control, flexibility, and stability during canine blood sampling.
Standard rigid needles often tear veins or slip out when active animals move during blood draws. Our butterfly needle utilizes soft, flexible tubing that absorbs animal movement while maintaining steady blood flow into micro vacuum collection tubes, ensuring smooth, less stressful blood sampling for both the pet and the veterinary staff.

Key Features & Clinical Advantages
- Flexible Tubing Design: Soft extension tubing acts as a buffer against patient movement, significantly reducing needle displacement and vessel trauma in active dogs.
- Ergonomic Winged Grips: Color-coded, textured wings provide precise angle control, tactile feedback, and non-slip stability during insertion.
- Micro Vacuum Tube Compatibility: Specifically engineered to interface seamlessly with veterinary micro blood collection tubes for rapid, low-volume specimen collection.
- Reduced Sampling Errors: Minimizes mechanical hemolysis and vessel collapse caused by animal flinching or shifting during multi-tube sampling.
- Ideal for Repeated Blood Draws: Gentle insertion profile makes it suitable for serial monitoring, pre-surgical panels, and intensive care sampling.
Clinical Veterinary Applications
These butterfly needles are primarily recommended for canine venipuncture across veterinary clinics, hospitals, and diagnostic research facilities:
- Large-Breed Dog Blood Sampling: Specially optimized for large dogs weighing over 30 kg (e.g., Golden Retrievers, German Shepherds, Labradors, Rottweilers).
- Restless or Anxious Animals: Blood collection from active or frightened pets where rigid needles pose a risk of vein laceration.
- Routine Wellness & Pre-Surgical Screening: Diagnostic health panels, pre-anesthetic blood profiles, and geriatric screenings.
- Serial Diagnostic Monitoring: Repeated venous sampling in intensive care units (ICU) and clinical pathology laboratories.

How to Use Veterinary Butterfly Blood Collection Needles
Follow standard clinical handling protocols during veterinary phlebotomy:
- Preparation: Select the appropriate needle specification (0.55×20 mm, 0.7×25 mm, or 0.8×28 mm) based on the animal’s vein condition.
- Disinfection: Disinfect the target venipuncture site (e.g., cephalic or lateral saphenous vein) and allow it to dry completely.
- Venipuncture: Pinch the flexible wings together and insert the needle bevel-up into the vein at a low angle.
- Tube Connection: Push the micro vacuum blood collection tube into the holder/adapter at the distal end of the flexible tubing to initiate blood flow.
- Withdrawal & Disposal: After collecting the required volume, withdraw the needle gently, apply hemostatic pressure to the puncture site, and discard the used needle into a sharps biohazard container.
Frequently Asked Questions
