SYSTEM AND METHOD FOR PREVENTING DECUBITUS ULCERS

摘要

A system to prevent the creation of pressure-wounds in a subject is provided, comprising at least one pressure detection mat comprising at least one layer of an insulating material sandwiched between first and second layers of conducting and a second layer of conducting strips overlapping at a plurality of intersections forming sensors, a driving unit configured to supply electrical potential selectively to the first layer' conducting strips, a control unit wired to the second layer's conducting strips and configured to control the driving unit and to receive data from the sensors, a processor configured to monitor electrical potential on the second layer's conductive strips to calculate impedance values and determine accumulated pressure applied thereto by calculating a summation of pressure measured by the sensor at predetermined intervals, and at least one display configured to present indications of pressure distribution and accumulated pressure.

1. A system configured to prevent the creation of pressure-wounds in a subject, comprising:
at least one pressure detection mat comprising at least one layer of an insulating material sandwiched between a first layer of conducting strips and a second layer of conducting strips, said conducting strips of the first layer and said conducting strips of the second layer overlapping at a plurality of intersections, wherein each intersection forms a sensor; a driving unit configured to supply electrical potential selectively to the conducting strips of the first layer; a control unit wired to the conducting strips of the second layer and configured to control said driving unit and to receive data from said sensors; a processor configured to monitor electrical potential on the conductive strips of the second layer, to calculate impedance values for each sensor and to determine accumulated pressure applied to said sensor by calculating a summation of pressure measured by the sensor at predetermined intervals; and at least one display configured to present indications of pressure distribution and said accumulated pressure.
