1. A negative pressure therapy system for a wound environment comprising:
a) a pump adapted to generate a negative pressure for the wound environment;
b) a film connected to the pump and positioned outward from a negative pressure sponge; the negative pressure sponge conforming to contours of the wound environment and the film forming a seal creating the negative wound environment;
c) a pressure sensor coating attached to at least a portion of an outer surface of the negative pressure sponge; the pressure sensor coating bendable with the outer surface of the negative pressure sponge and adapted to sense positive, negative and zero pressures associated with the wound environment; and
d) a monitor/controller intercommunicating with the pressure sensor coating and the pump; the monitor/controller comprising software adapted to:
i) quantify the positive, negative and zero pressures sensed by the pressure sensor coating;
ii) cause the controller to automatically control the negative pressures supplied by the pump to the wound environment, wherein the controller's automatic control is dependent on the positive, negative and zero pressures sensed by the pressure sensor coating; and
iii) create a visual graphic depiction on the monitor of simultaneous negative, positive and zero pressures associated with the wound environment, wherein the visual graphic depiction assists a user in remotely and manually controlling the negative, positive and zero pressures of the wound environment and negative pressure supplied by the pump to the wound environment.
