RESEARCH ON VEIN FINDER INSTRUMENT DESIGN USING TWOWAVELENGTH OPTICAL METHOD

Abstract

In intravenous injection manipulation, popular visual method of fast and accurate finding of veins strongly depends on patient body and physician experience. Especially for geriatric, pediatric or obese patients, nurses or paramedics may fail in the first intravenous injection and have to repeat many times, which causes a lot of pains or discomforts for the patients. This paper will introduce some studies on imaging of vein using two-wavelength optical method, on basis of which a vein finder instrument can be optimally designed for supporting intravenous injection manipulation.
