Safety Needles

SAN-L®

Automatic Safety Needle for Luer-lock Syringes

SAN-L® is an automatic, single-use safety needle for subcutaneous or intramuscular drug administration, designed for confident and safe self-injection. Featuring a small form factor, it attaches to any Luer-lock syringe, adding automatic needle insertion and a passive safety shielding mechanism, with no changes to the syringe itself.

The SAN-L® equips a Luer-lock syringe with these unique features, enabling the user to control injection speed manually by pressing the plunger rod. The SAN-L® also keeps the needle hidden throughout the whole injection process. By that, the SAN-L helps in reducing needle anxiety and lowering perceived pain.

Before / After

SAN-L® combines automatic needle insertion, a hidden needle before, during, and after use, and passive sharps protection for simple self-injection that promotes compliance.
