Body heat removal system for prevention of hyperthermia with thermoelectric devices

为了防止脊髓损伤的人变得体温过高，我们开发了一种带有热电装置的身体排热系统（BHRS）。 我们表征了冷却系统引起的热生理反应。 在炎热环境中对身体健全的受试者进行的冷却实验表明，与非冷却（NC）试验相比，后冷（BC）试验中的出汗和收缩压得到显着抑制。 在 NC 试验中观察到胸部皮肤温度和血流量之间存在相关性； BC 试验中没有观察到这一点。 这些结果表明 BHRS 调节正常的体温调节反应，包括出汗和血管扩张，并有能力部分替代这些功能。

To prevent such individuals with spinal cord injuries from becoming hyperthermic, we developed a body heat removal system (BHRS) with thermoelectric devices. We characterized thermophysiological responses induced by the cooling system. A cooling experiment in a hot environment with able-bodied subjects demonstrated that sweating and systolic blood pressure in the back-cooling (BC) trial were significantly suppressed compared with those in no-cooling (NC) trial. A correlation was observed between chest skin temperature and blood flow in the NC trial; this was not observed in the BC trial. These results suggest that BHRS modulates normal thermoregulatory responses, including sweating and vascular dilation and has the capability to partly replace these functions.
