Patient support apparatus
First Claim
1. A patient support apparatus comprising:
- 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, wherein each sensing element is configured to determine, in use, a force or pressure applied to it by the patient support element and a patient on the patient support element; and
one or more processors, coupled to the sensing elements, the one or more processors being configured to;
determine a 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;
determine a load variation, being a variation in total force applied to the sensing elements by the patient support element and a patient on the patient support element;
receive user input selecting one of two or more presets, each preset corresponding to a patient movement sensitivity level and comprising a predetermined range of values for the location of the center of gravity and/or a predetermined load variation value stored on a memory;
access the memory to receive the parameters associated with the selected preset; and
provide an output to activate an alarm when the location of the center of gravity along the width of the patient support apparatus is outside the predetermined range of values and/or the load variation exceeds the predetermined value, wherein the one or more processors are further configured to receive an input indicative of a type of patient support element and to adjust the location for the center of gravity, or the predetermined range of values for the center of gravity, based upon the input.

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.
