Abstract: A patient support apparatus, such as a bed, cot, stretcher, etc., includes a scale system adapted to automatically monitor changes in a patient's weight over the course of a patient's stay within a healthcare facility. A controller onboard the patient support apparatus is configured to take an initial weight reading of the patient when he or she is first assigned to the patient support apparatus, and to thereafter repetitively compare the patient's current weight to that initial weight reading. If the difference exceeds a threshold, the controller issues a notification. The threshold may be user-customizable and/or it may be adaptive based on s statistical analysis of the patient's weight fluctuations. A control panel may be included to allow a caregiver to select between using a non-adaptive threshold or an adaptive threshold, and/or to select a value for the non-adaptive threshold. The notification may be transmitted to the caregiver's smart phone.

Abstract: A patient support apparatus, such as a bed, cot, stretcher, etc., includes a plurality of force sensors that may be used for implementing a scale function and/or an exit detection function. A controller onboard the patient support apparatus is adapted to determine if a patient's center of gravity is within a zone as a prerequisite for carrying out the exit detection function. If the patient's center of gravity is outside the zone, the controller provides graphical guidance to the user regarding the patient's current center of gravity and a target location where the patient's center of gravity should be. The controller may also provide graphical guidance for a user to implement a calibration process for the force sensors, and in some case, one or more accelerometers. The controller may also simultaneously display successive calculations of the patient's center of gravity with a directional indicator showing a direction of its movement.

Abstract: A patient support apparatus, such as a bed, cot, stretcher, etc., includes a scale system adapted to automatically detect when an object is added to a support surface of the patient support apparatus. An onboard controller is configured to take one or more actions in response to the detection of the added object. Such actions include, but are not limited to, sending a message wirelessly to the object, capturing an image of the object with a camera, marking a segment of a video that encompasses the addition of the object, and/or determining if a change in a center of gravity caused by the addition of the object can be completely attributed to the object's addition, or if it is due to other factors, such as patient movement. A display may show a bed icon with an object icon positioned at the same location as the object.
