Patient-need prediction system
First Claim
1. A patient-need prediction system comprisinga sensor unit configured to detect electromagnetic radiation from a field of view and provide a sensor signal indicative of a characteristic of a patient in the field of view,a bed sensor unit configured to provide a bed-sensor signal indicative of a status of equipment included in a patient support apparatus supporting the patient, anda controller coupled to the sensor unit and configured to process the sensor signal to produce a value related to a stress condition experienced by the patient located in the field of view as detected by the sensor unit, determine whether the value has exceeded a predetermined limit, and perform a predetermined action if the value has exceeded the predetermined limit,wherein the controller is coupled to the bed sensor unit and is further configured to process the bed-sensor signal and the sensor signal to produce the value related to the stress condition experienced by the patient located in the field of view as detected by the sensor unit, andwherein the stress condition is at least one of a need to urinate and defecate by the patient.

Abstract
A patient support apparatus includes a control system operable to gather physiological information about a patient supported on the patient support apparatus. The information may be gathered from sensors, a user interface, or a hospital information system. The control system uses the data gathered to predict whether a patient is likely to be in need of care from a caregiver.

16. A patient-need prediction system comprising
a patient sensor unit configured to detect electromagnetic radiation from a field of view and provide a patient sensor signal indicative of a characteristic of a patient in the field of view, a patient support apparatus adapted to support the patient thereon, a portion of the patient support apparatus is located in the field of view, and a bed sensor unit configured to provide a bed-sensor signal indicative of a status of a component of the patient support apparatus, wherein the patient support apparatus includes a controller coupled to the patient sensor unit to receive the patient sensor signal and to the bed sensor unit to receive the bed-sensor signal and configured to produce a value related to stress experienced by the patient located in the field of view as detected by the patient sensor unit and the bed sensor unit, to determine whether the value has exceeded a predetermined limit, and to perform a predetermined action if the value has exceeded the predetermined limit, wherein the stress is caused by at least one of a need to urinate and defecate by the patient.

21. A patient-need prediction system comprising
a patient sensor unit configured to detect electromagnetic radiation from a field of view and provide a patient sensor signal indicative of a characteristic of a patient in the field of view, a controller coupled to the patient sensor unit and configured to process the sensor signal to produce a value related to a stress condition experienced by the patient located in the field of view as detected by the sensor unit, to determine whether the value has exceeded a predetermined limit, and to perform a predetermined action if the value has exceeded the predetermined limit, wherein the predetermined action includes communicating to the patient that a caregiver has been summoned.
