Vein finder, VF-F31
Description
Uses:
- Hand held, light and portable
- Observe the venous conditions of patients in advance to
ensure the effectiveness of venipuncture.
Working principle
According to the principle that the absorption rate of near-infrared light of deoxyhemoglobin in venous blood is different from that of other tissues, the subcutaneous blood vessels are projected on the skin surface in situ by a series of means, such as infrared back light scattering image collection micro projection technology. In order to achieve a clear display of subcutaneous blood vessels.
