Claim 0:
1. A skin perfusion pressure determination device comprising a housing including a proximal end and a distal end, and wherein the skin perfusion pressure determination device further comprises:
a plunger assembly at the proximal end of the housing configured to contact and exert force on a target area, the plunger assembly comprising a support structure and a sleeve surrounding the support structure, wherein the plunger assembly is configured to move in a proximal to distal direction relative to the housing from a first expanded configuration in which the plunger assembly extends proximally from the proximal end of the housing to a second retracted configuration in which the plunger assembly is retracted into the housing responsive to a force being exerted on the target area;
a sensor module provided within the housing and/or the plunger assembly, the sensor module configured to detect the force exerted on the target area and an amount of blood perfusion at the target area;
a display to provide feedback of the force exerted on the target area; and
a spring at the distal end of the housing configured to exert a force on the plunger assembly and control the force exerted on the target area.
