Venipuncture is an important health diagnosis process. Although venipuncture is one of the most commonly performed procedures in medical environments, locating the veins of infants, obese, anemic, or colored patients is still an arduous task even for skilled practitioners. To solve this problem, several devices using infrared light have recently become commercially available. However, such devices for venipuncture share a common drawback, especially when visualizing deep veins or veins of a thick part of the body like the . This paper proposes a new vein-visualizing device applying a new penetration method using near-infrared (NIR) light. The light module is attached directly on to the declared area of the skin. Then, NIR beam is rayed from two sides of the light module to the vein with a specific angle. This gives a penetration effect. In addition, through an image processing procedure, the vein structure is enhanced to show it more accurately. Through a phantom study, the most effective penetration angle of the NIR module is decided. Additionally, the feasibility of the device is verified through experiments in vivo. The prototype allows us to visualize the vein patterns of thicker body parts, such as arms.
静脉穿刺是一种重要的健康诊断过程。虽然静脉穿刺是医疗环境中最常见的程序之一，但即使对于熟练的医生来说，定位婴儿、肥胖、贫血或有色人种的静脉仍然是一项艰巨的任务。为了解决这个问题，最近已经有几种使用红外光的设备上市。然而，这些用于静脉穿刺的设备有一个共同的缺点，特别是在可视化深部静脉或像 这样身体较厚部位的静脉时。本文提出了一种新的静脉可视化设备，该设备采用了一种新的近红外（NIR）光穿透方法。光模块直接贴在皮肤的指定区域上。然后，NIR 光束从光模块的两侧以特定角度射向静脉。这产生了穿透效果。此外，通过图像处理过程，增强了静脉结构以更准确地显示它。通过体模研究，确定了 NIR 模块的最有效穿透角度。此外，还通过体内实验验证了该设备的可行性。该原型允许我们可视化较厚身体部位（如手臂）的静脉模式。
