摘要： An apparatus for evaluating perfusion adjacent a skin surface includes a housing having first and second interior regions. The housing is configured to engage the skin surface. The apparatus also includes a plunger located in the first region of the housing for applying pressure to a first zone of the skin surface, a vacuum connection coupled to the second region of the housing to permit suction to be applied to the second region of the housing and to a second zone of the skin surface, a first temperature sensor for generating an output signal related to the temperature of the first zone of the skin surface, a second temperature sensor for generating an output signal related to the temperature of the second zone of the skin surface, and a processor circuit coupled to the first and second temperature sensors for determining a differential temperature between the first and second zones of the skin surface to provide an indication of perfusion adjacent the skin surface.
