A Low-Cost Vein Pattern Detector for Clinical Diagnostics and Non-Intrusive Medical Monitoring

Abstract

The vein pattern detector (VPD) stands as a revolutionary invention in the healthcare industry, evolving into a critical tool especially for healthcare-workers (HCW)s. In general, this device employs near-infrared (NIR) light reflection to create a vein mapping. In today’s date, such technology has not been widely adopted despite its potential benefits because of factors like its high-cost and restricted accessibility. Due to such reasons, phlebotomists consequently experience complications with instantly distinguishing veins, resulting in pre-analytical errors and triggering more discomfort for the patient. To address such challenges, the study aimed on developing a prototype system for detecting vein, with particular emphasis on affordability and portability. The study yielded significant outcomes in assessing subjects across varying categories ranging from underweight to obese subjects. By addressing constraints of the cost, the results highlighted the low-cost system's potential to examine the vein, making it widely accessible especially for facilities with limited financial resources.
