Abstract：
Venipuncture for blood collection is frequently delegated to medical or nursing students, while their individual skills depend on the quality of teaching. The aim of this study was to evaluate the use of a near infrared imaging (NIR) system on the visualization of veins and its potential benefit for the education of medical personnel. Participants answered a questionnaire following standardized venipuncture for blood sampling with the help of an NIR device. Vein visibility with the NIR device and its ability to facilitate venipuncture were examined. Visibility of veins was significantly better with the NIR, and its direction was clearly delineated. Sixty-nine percent of the participants stated that they felt more secure with venipuncture after using the NIR device. Patients\' individual factors limited the visibility of veins. The adjuvant use of an NIR system for venipuncture improves participants\' subjective skills through visualization of veins and their direction.
摘要：
用于采血的静脉穿刺经常委托给医学或护理专业的学生，而他们的个人技能取决于教学质量。这项研究的目的是评估近红外成像（NIR）系统在静脉可视化中的使用及其对医务人员教育的潜在益处。参与者在NIR设备的帮助下进行标准化静脉穿刺采血后回答了问卷。检查了使用NIR设备的静脉可见性及其促进静脉穿刺的能力。通过NIR，静脉的能见度明显更好，它的方向被清楚地描绘了。69%的参与者表示，他们在使用NIR设备后感到静脉穿刺更安全。患者的个体因素限制了静脉的可见性。NIR系统用于静脉穿刺的辅助使用通过可视化静脉及其方向来提高参与者的主观技能。
