外周血流的无损伤测量在临床医学中的潜在用途十分广泛。迄今已进行的测量几乎都是针对外周循环疾病及血管痉挛患者,而对经手术后的肢体和手指的血流信息所知甚少。创伤后肢体及手指血流研究工作中存在的困难,主要在于受试对象与测量仪器的连接,快速重复读数,计算复杂,测量必须在控温环境中进行等几个方面。对于因肢体升高、运动、反应性充血和温度变化所引起的 The potential use of non-invasive measurement of peripheral blood flow in clinical medicine is very broad. Almost all measurements taken so far have been directed at patients with peripheral circulatory diseases and vasospasm, and little is known about the flow of blood through the limbs and fingers after surgery. Traumatic limbs and finger blood flow in the work of the existing difficulties, mainly in the test subjects and measuring instruments, fast repeat readings, computational complexity, the measurement must be carried out in several areas such as temperature control. For the rise of limbs, exercise, reactive hyperemia and temperature changes caused
