Patient support apparatus having articulated mattress support deck with load sensors
First Claim
1. A patient support apparatus comprisinga main frame,an articulated mattress support deck supported on the main frame, the articulated mattress support deck comprising a seat section, a head section that articulates relative to a head end of the seat section, a thigh section that articulates relative to a foot end of the seat section, and a leg section that articulates relative to the thigh section,wherein at least one of the seat section and the thigh section includes a section frame, a mattress support panel, and a plurality of load sensors supporting the panel above the section frame, the plurality of load sensors providing signals indicative of a portion of a patient'"'"'s weight,one or more processors coupled to the plurality of load sensors, anda mattress supported on the articulated mattress support deck, wherein the one or more processors are configured to process signals from the plurality of load sensors differently depending upon whether an input to the one or more processors indicates that the mattress is a foam mattress or an air mattress.

Abstract
A patient support apparatus comprises a substantially rigid support deck for supporting a patient support element, a first sensing element and a second sensing element arranged on the support deck and separated from one another in a direction along the width of the patient support apparatus. Each sensing element is configured to determine, in use, the force or pressure applied to it by the patient support element and a patient on the patient support element. One or more processors, coupled to the sensing elements, are configured to determine the location of the center of gravity of a patient on the patient support element, along the width of the patient support apparatus, based upon outputs of the first and second sensing elements. An alarm may be activated when the location of the center of gravity along the width of the patient support apparatus is outside a predetermined range of values.
