Implementing light emitting diode technology for vein detections

Abstract

In diagnosis or medical treatment, the act of intravenous intervention is the important work before conducting tests. Intravenous skills are essential for medical staff to reduce patient’s pain in an injection. However, it is difficult for inexperienced staff to perform intravenous injections to patients whose veins are hard to find such as obese patients, women, and children. In this paper, we present three non-invasive subcutaneous vein detection devices based on light-emitting diode technology. Three designed devices are Vein 1, Vein 2, and Vein 3 which help therapist improve the accuracy in intravenous intervention. Vein 1 and Vein 2 are handheld devices using Red LED 630, nm and Orange LED 580, nm whereas Vein 3 utilizes near infrared LED 900, nm connecting with USB IR-Cut camera and a laptop for image processing. Each device is designed with a specific objective in diagnosis and treatment. Vein 1 is used for quick vein detection in a small area. Vein 2 is used for vein detection in a thick portion such as fingers, hands or laboratory animals. And Vein 3 is used to detect in a large area for detecting venous diseases. From the achievements of experimental results, all three devices work well as expected.
