Bandage Pressure Sensor

(canceled)

A method of providing an indication of the pressure applied by a bandage to a human or animal body, the method comprising the step of positioning a disposable sensor between a bandage and the body, the sensor comprising a flat, flexible support carrying a flat, flexible pressure sensitive portion whose electrical properties vary with applied pressure perpendicular to the general plane of the support strip, and also carrying flat, flexible conductors which connect the pressure sensitive portion to a supply of electricity and to means for providing an indication of the applied pressure.

A pressure sensor for providing an indication of the pressure applied by a bandage to a human or animal body, the sensor comprising an flexible support substrate adapted to be placed between a bandage and the body, the support substrate carrying a flat pressure sensitive portion in the form of a flexible membrane whose electrical properties vary with applied pressure perpendicular to the plane of the membrane, and also carrying flat, flexible conductors for connecting the pressure sensitive portion to a supply of electricity and to means for providing an indication of the applied pressure.

A pressure sensor for providing an indication of the pressure applied by a bandage to a human or animal body, the sensor comprising an flexible support substrate adapted to be placed between a bandage and the body, the support substrate carrying (a) a flat pressure sensitive portion whose electrical properties vary with applied pressure perpendicular to the plane of the substrate;

• (b) a battery;
• (c) means for providing an indication of the applied pressure;
• and (d) flexible conductors which connect the pressure sensitive portion to the supply of electricity and to the means for providing an indication of the applied pressure.

A method of applying a bandage to a human or animal body, in which there is provided an indication of the pressure applied by the bandage to the human or animal body and the bandage is applied in such a way that the applied pressure is kept within predetermined acceptable limits, the method comprising the step of positioning between the bandage and the body, a sensor comprising an flexible support substrate carrying (a) a flat pressure sensitive portion whose electrical properties vary with applied pressure perpendicular to the plane of the substrate;

• (b) a battery;
• (c) means for providing an indication of the applied pressure;
• and (d) flexible conductors which connect the pressure sensitive portion to the supply of electricity and to the means for providing an indication of the applied pressure.
