TAILIEUCHUNG - Research on vein finder instrument design using twowavelength optical method
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. | TAÏP CHÍ PHAÙT TRIEÅN KH&CN, TAÄP 15, SOÁ K1- 2012 RESEARCH ON VEIN FINDER INSTRUMENT DESIGN USING TWOWAVELENGTH OPTICAL METHOD Tran Van Tien, Huynh Quang Linh, Nguyen Anh Hang University of Technology – VNUHCM (Manuscript Received on April 5th, 2012, Manuscript Revised November 20rd, 2012) 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.

INTRODUCTION Injection needles are the most common and greatest source of procedural pain for patients, especially in immunizations, intravenous pediatrics glucose injection, [1]. In quick monitoring, laceration repairs, dermatologic procedures and even tattooing, needle pain is a major growing concern. These effects may be amplified with age, children avoid medical treatment, 16% to 75% of surveyed adults refuse to donate blood and geriatric patients refuse flu shots due to fear of needle pain [2,3]. The health implications of needle phobia extend beyond the affected individuals, HIV patients continued to infect others while delaying blood tests and needle phobic parents are less likely to immunize their children [4]. It is important to minimize the discomfort associated with needle injection for patients more than once; especially even skilled nurses or paramedics may be very often unsuccessful in such manipulation .
