Fluid supply control for patient support surface

摘要

A control system of a patient support surface calculates a surface performance index as a function of pressure and shear. The control system also receives information from an electronic medical record (EMR) corresponding to a person's susceptibility of developing at least one of a pressure ulcer and a superficial lesion and adjusts at least one of a component and a characteristic of the person support surface based on the information.

主权项

1. A person support surface comprising
at least one inflatable bladder, a low air loss topper including a portion above the at least one inflatable bladder, and a control system including a plurality of sensors that generate data signals indicative of a characteristic of the at least one inflatable bladder and a person's tissue supported above the low air loss topper, a processor operatively coupled to the plurality of sensors, the processor being configured to execute operating logic to determine a surface performance index as a function of the data signals, and a fluid supply coupled to the at least one inflatable bladder and to the low air loss topper, the processor controlling the operation of the fluid supply to deliver fluid flow through the low air loss topper as a function of the surface performance index to control at least one of convective evaporation and diffusive evaporation.
