SensorCells Limit Tissue Contact Pressure
The chief design element of this system is an array of inflatable SensorCells that replace the spring elements of a
conventional mattress. In a normal mattress, the support force increases as the mattress is compressed, resulting
in an increase of interface pressure that makes bony and prominent areas vulnerable. TheraTorr's SensorCells are
designed to apply constant upward force as they are compressed. The figure below compares the typical behavior
of spring and foam mattresses to that of a SensorCell. TheraTorr's technology is uniquely able to limit contact
The SensorCell upward force
remains constant for the entire
depth of response - A full 5 inches!
A deeper effective cradle allows a
patient's weight to be distributed
over a greater surface area, thus
reducing the tissue contact
Each of the 500+ cells forming a TheraTorr therapeutic surface acts independently to lift and support the contours
of the patient's body, without allowing tissue pressure to exceed the system setting.The currently available,
powered pressure-reduction beds have less than 25 horizontally-oriented air pillows. Such a small number of
cells is not as efficient at distributing pressure, requires a higher systen pressure for flotation and cannot
effectively control pressure at bony areas.
