DERUK, a brand of Shenzhen Deruk Technology Co., Ltd., offers professional vein visualization devices with medical device registration. The product range includes LCD and projection models.

All models work on the same near‑infrared principle: deoxygenated hemoglobin absorbs NIR light differently from surrounding tissue, producing a clear real‑time vascular image on screen or projected onto the skin.

Beyond locating veins, DERUK devices also help assess blood filling, monitor drug flow, and detect post‑injection hematoma.

Clinical Applications:
Suitable for superficial veins on the face, neck, arms, hands, legs, and feet. Widely used in pediatrics, oncology, geriatrics, emergency, surgery, dialysis, labs, and aesthetic medicine—anywhere venipuncture is performed.

Intended Use: "For observing subcutaneous superficial veins and assisting venipuncture." The device does not replace clinical judgment but provides enhanced visual guidance for safer, faster, and more patient‑friendly procedures.

Conclusion:
DERUK vein finders combine portability, high‑quality imaging, and long battery life, making them reliable partners in daily clinical work. Whether for difficult patients or routine efficiency, they ensure every puncture is guided by clear vision—reducing pain, anxiety, and risk for everyone involved.
