As healthcare systems worldwide place increasing emphasis on patient comfort and clinical efficiency, the demand for safer and more versatile blood collection devices continues to grow. Butterfly needles, commonly used for venipuncture, remain a standard choice across a wide range of clinical settings.
SHANGHAI HXRT MD focuses on delivering consistent product quality while maintaining cost efficiency—an important consideration for hospitals, laboratories, and large-scale diagnostic centers.
Core Science: Single-Use vs Dual-Purpose
In clinical venous blood collection, butterfly needles are widely preferred for their ease of use and enhanced patient comfort. They are especially valuable when working with patients who have fragile or hard-to-access veins. However, when it comes to choosing between single-use and double-ended butterfly blood collection sets, many users find the differences unclear.
To help clarify this, this article provides a straightforward overview of both types, highlighting their principles, features, and how to pick the right one!
Single-use Butterfly Needle: The “Specialist” for Routine Sampling
Key Features & Pros
- Structural Design: Only one end has a blood collection needle; the other end is a closed/single-path interface, matched with a vacuum blood collection tube hub
- Core Function: Only supports venous blood collection (via vacuum negative pressure for blood sampling; no other uses).
- Clinical Advantages: Simple structure, low cost; stable negative pressure during sampling, suitable for batch routine blood collection scenarios
Dual-purpose butterfly needle: The “All-Rounder” for Integrated Care
Key Features & Pros
- Structural Design: Both ends have needles: one end is a butterfly blood collection needle (for venous puncture), the other is an injection needle (compatible with syringes or vacuum blood collection tubes).
- Core Function: Combines dual functions: venous blood collection + intravenous injection/infusion (can switch directly to the injection port for drug administration after blood collection).
- Clinical Advantages: Eliminates the need for secondary puncture, reducing patient discomfort; allows direct drug administration after blood collection, improving efficiency in emergency/special treatment.
Choosing the Right Solution for Clinical Needs
Rather than replacing one another, single-use and dual-purpose butterfly needles address different clinical priorities. Single-use designs remain a practical and economical option for routine sampling, while dual-purpose needles provide added flexibility in integrated care settings.
As a professional laboratory and medical consumables manufacturer and supplier, SHANGHAI HXRT MD offers both single-use and dual-purpose butterfly needles. Our butterfly needle is available in multiple gauge sizes, including 20G, 21G, 22G, 23G, and 25G. In addition, it comes in multiple color options: yellow, green, black, blue, and orange. It is easy to identify and use during work.
Our butterfly needles offer numerous features include:
- High polymer materials, EO sterilized, non-toxic, non-homogeneous and non-pyrogenic;
- Easily identified by different color;
- Higher transparency tube allows the user to best observe the venous return;
- Sharp needle and high-quality lubricant design can reduce puncture pain.
The comparison between single-use and dual-purpose butterfly needles illustrates how venous access devices are adapting to varied clinical requirements. Both designs offer practical advantages when applied to appropriate clinical workflows.
