How can vein finder complement the workflow of ophthalmic medicine and imaging equipment?
Nov 27 , 2025
1) Core Value: Provide a unique "surface vascular map" Ophthalmic imaging equipment (such as OCT) focuses on the microscopic vascular structure of the fundus (retina, choroid), while venous detectors are adept at non-invasively visualizing the vascular network on the ocular surface and around the eye, especially: The blood vessels of the sclera and conjunctiva The blood vessels of the skin around ...

How deep can a medical vein finder see?
Jan 27 , 2026
1. Main detection depth General depth: Most devices can detect veins 0.2 to 1.0cm beneath the skin, but the actual effective imaging range is usually concentrated on the shallower veins under the skin (0.2 to 1.0 cm). Best effect: For clearly visible superficial veins (such as the back of the hand and forearm), the imaging effect is the best. 2. Key influencing factors Skin condition Skin color, f...

Feb 10 , 2026
The following differences also need to be considered when making a choice: 1. Display mode Direct vision/projection: Project the vascular image directly onto the patient's skin. The advantage is that the operator does not need to shift their gaze and their hands and eyes are in perfect coordination. The drawback is that the projection may deform due to the curved surface of the skin. Screen displa...
