First Claim
Patent Images
1. In a pressure adjustable support, including a bladder assembly having a plurality of bladders to support a patient, a plurality of sensors, each of the plurality of sensors subtending at least one of the vertical bladders to sense a force transmitted through the bladders, a method comprising the steps of:
- setting a time period for determining an activity level;
setting a threshold level with respect to the sensed force;
sampling the forces sensed by each of the plurality of sensors transmitted through the bladders; and
generating a signal as a function of the set time period, the set threshold level, and the sampled forces.

Abstract
A lack of patient movement monitor and method. The monitor and method patient support includes a plurality of sensors located beneath a patient support to determine movement of a patient. An alarm is activated when patient movement over time is determined to be lacking.
