| abstract | A device for refrigerating a small area of the skin for several cycles is used to measure the condition and effectiveness of the capillary network in bringing the skin temperature back to normal. The system includes a heat exchanger (10) attached to the skin. Measured quantities of a liquid having a low boiling point are injected into a refrigeration chamber (76). One side of the chamber (76) includes a conductive material in contact with the skin. Heat from the skin boils the liquid, which in turn cools the heat conducting material (22) and the skin. A wick (26) helps transport the liquid to the heat conducting surface (22). A container (120) is used to hold the liquid. A movable divider (137) separates the container (120) into two spaces. A liquid with a low boiling point is stored on one side of the divider (137). The second space contains a fluid having a substantially higher vapor pressure than the first fluid, so that the pressure of the second fluid pressurizes the first fluid, maintains it in the liquid state and pushes it into the heat exchanger (10 ). The flow is controlled by a valve (354) mounted in the heat exchanger (10). In another embodiment, an intermediate injector or valve (226) receives the liquid having a low boiling point from the container (120) and transmits it to the heat exchanger (10) in response to signals sent by a computer (280). The computer (280) also receives signals related to skin temperature to maintain the skin temperature within a measurement bandwidth. The heat exchanger (10) is also useful in other systems, such as generalized body refrigeration systems in high temperature environments. |
