本文介绍了微波-光学混合式肌肉体温监测器的最新进展。它能够加热肌肉并测量随后的血液容量变化,使用一种带有集成光学探头的新型微波辐射器。挑战是测量深层组织的体温调节反应,同时将皮肤层的影响降至最低。我们引进了一个皮肤降温装置,一个额外的集成光学激光多普勒血流监测探头和一个温度传感器,分别测量皮肤的血流和温度。结果表明,在微波加热过程中,皮肤降温是减少皮肤流量变化的关键。混合探头被放置在人的大腿上,以测量微波加热时氧/脱氧/总血红蛋白浓度(ΔHbO2/ΔHHb/ΔHbt)、皮肤流量和温度的变化。在没有皮肤降温的情况下,皮肤温度升高了4°C,ΔHbO2/ΔHbt和皮肤流量都增加了,表明皮肤和肌肉都发生了微波加热。随着皮肤降温,皮肤温度保持相对恒定。当ΔHbO2/ΔHbt增加时,皮肤流量相对稳定,显示出优先于肌肉的微波加热,而不是皮肤。
This paper presents the latest development of the hybrid microwave-optical thermoregulation monitor for the muscle. It is capable of warming the muscle and measuring the subsequent blood volume changes, using a novel microwave applicator with integrated optical probes. The challenge is to measure the thermoregulation response in deep tissue while minimizing any effect from the skin layer. We have introduced a skin cooling device, an additional integrated optical Laser Doppler flow monitoring probe and a temperature sensor to measure skin blood flow and temperature, respectively. The result shows that skin cooling is essential to minimize skin flow changes during microwave warming. The hybrid probe was placed on a human thigh to measure oxy/deoxy/total haemoglobin concentration changes (ΔHbO2/ΔHHb/ΔHbT), skin flux and temperature upon microwave warming. Without skin cooling, the skin temperature was elevated by 4 °C and both ΔHbO2/ΔHbT and skin flux increased, showing microwave warming occurring in both the skin and muscle. With skin cooling, the skin temperature was kept relatively constant. While ΔHbO2/ΔHbT increased, the skin flux was relatively stable, showing a preferential microwave warming in the muscle, rather than the skin.
