Blood collection needle XLPⅠ-21G

22G21G

Product overview
Flashback needles provide immediate visual confirmation of blood return through a transparent flashback window once the cannula enters the vessel. They are intended for controlled vascular access during injections and blood sampling and are designed for use in a clinical environment by trained healthcare professionals.

Key advantages

• Real-time visualization of blood return: Transparent flashback window shows blood once the needle tip penetrates the vein, confirming intravascular placement and reducing incorrect placements.
• Improved patient comfort and efficiency: Visual confirmation supports first-attempt success, reducing procedure time and patient discomfort.
• Optional safety features: Models may include retractable needles or protective covers to lower needlestick risk for staff and patients.
• Versatile clinical use: Suitable for IV injections, blood collection, subcutaneous and intradermal injections, and specialized procedures (central line assistance, regional anesthesia, contrast administration).

Illustrative note
The blood becomes visible in the transparent window when the cannula properly penetrates the vein, providing immediate confirmation of vascular access.
