DUOSAFE Technology Highlights

Technology

Comfort comes from engineering, safety begins with design

TrueCushion delivers comfort, TrueLock ensures safety. Together, they embody the core technological commitment behind the entire DUOSAFE product lineup.

True buffer system

Through innovative mechanical design, it reduces vibration and contact pressure during lancing, delivering a more consistent and comfortable blood sampling experience.

Multiple guide rails ensure precise control of the lancet’s path, angle, and penetration depth, while a customized spring system releases force in stages to minimize sudden impact, noise, and vibration.

The 3D curved decompression design fits the blood collection site and disperses the contact pressure.

True security system

Securely locked when it needs to be, preventing unintended activation or needle exposure.

A safety switch prevents accidental activation, while one-handed lancet ejection minimizes the risk of contact with the needle.

Dual Safety Lock: Prevents activation until the safety tab is removed. | Automatic Retraction: Ensures the needle tip remains permanently concealed after activation.

DUOSAFE Lancing Device (LD-E1): Safety Switch and One-Handed Lancet Ejection Mechanism, with Patent Coverage in Taiwan, the United States, China, and South Korea.
DUOSAFE Safety Lancet (MSL1): Pain-Reducing Structure and Method for a Single-Use Safety Lancet, Taiwan Invention Patent No. I749984.

Main product

Featured Products

The Medifun DUOSAFE family integrates two core design principles, TrueCushion and TrueLock, to deliver lancing solutions that prioritize both comfort and safety. Rather than being exclusive features of a single product, TrueCushion and TrueLock represent the technological commitment shared across the entire DUOSAFE product line.

DUOSAFE Lancing Device

Gentle Lancing, Safe Retraction.

The TrueCushion System delivers gentle cushioning with six adjustable penetration depths, while the TrueLock Safety System enhances safety through a safety switch and one-handed lancet ejection mechanism.

DUOSAFE Safety Lancet

Safety from Activation to Disposal.

TrueCushion features a 3D contoured surface that distributes contact pressure for enhanced comfort, while TrueLock incorporates a dual safety lock and automatic needle retraction to help prevent accidental needlestick injuries.

Standard blood collection needle

Three beveled needle tips, stable supply. Gamma ray sterilization, compatible with most commercially available blood collection pens.
