Abstract: A person support apparatus, such as a bed, cot, stretcher, chair, or the like, includes a frame, a support surface supported by the frame, a plurality of load cells that detect weight supported on the support surface, at least one A/D converter, and a controller. The load cells output analog signals that are converted to digital by the A/D converters. The controller switches a sampling rate of the A/D converters between at least first and second rates. The outputs from the load cells are forwarded to a plurality of signal acquisition nodes that include the A/D converters. The nodes are positioned at locations that minimize the length of travel of the analog signals, thereby reducing noise interference. Shivering, occupant absence/presence, vital signs, occupant movement, and/or other parameters are detected by the load cells.

Abstract: A patient support apparatus includes a plurality of primary sensors adapted to measure different parameters used in the control of the patient support apparatus. One or more suites of secondary sensors are added to the patient support apparatus to provide data about the primary sensors. The secondary sensors may be used to detect errors in the primary sensors, to modify outputs from the primary sensors, and/or to provide usage and/or diagnostic data about the use of the patient support apparatus. The suite(s) of secondary sensors may measure parameters that affect the outputs of one or more of the primary sensors. In some embodiments, the suite(s) of secondary sensors include one or more dormant sensors that are not used on the patient support apparatus until a code modification is received from one or more external sources instructing the control system of the patient support apparatus to begin using the dormant sensor(s).

Abstract: A person support apparatus, such as a bed, cot, stretcher, or the like, includes an exit detection system that has, in some embodiments, multiple user-selectable modes. A first mode issues an alert in response to a static condition being met and the second mode issues an alert in response to a dynamic condition being met. The static condition may be defined by an unchanging boundary that triggers an alert if the occupant's center of gravity crosses the boundary. The dynamic condition may be defined by a changing boundary that triggers an alert if the occupant's center of gravity crosses it. The changing boundary may change based upon the occupant's height, weight, BMI, vital sign, or other characteristic. The changing boundary may also change based upon a position of one or more components of the person support apparatus, such as a siderail or Fowler section.

Abstract: A patient support apparatus, such as a bed, cot, stretcher, etc., includes a control panel having a touchscreen display adapted to display a plurality of screens thereon. A controller automatically displays a lock screen on the display after a period of non-use and prevents the user from navigating to a different screen until the user drags a slider icon across the display and thereafter continues to press down on the slider icon for a predetermined time period. The controller may alternatively, or additionally, be adapted to display a litter frame tilt angle on the lock screen. The controller may alternatively, or additionally, display a motion control screen that includes a first lock indicator when a first motion control is in a locked state, and that adds a second lock indicator when a user presses on the first motion control while it is in the locked state.

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.

Abstract: A patient support apparatus, such as a bed, cot, stretcher, etc., for supporting a patient includes an exit detection system with multiple user-selectable modes of operation that each have different sensitivity levels for triggering an exit alert. The exit detection system also includes one or more non-user selectable modes of operation that are automatically implemented in response to a triggering action. For example, a transition mode may be automatically implemented when the user attempts to switch from a first user-selectable mode to a different user selectable mode, or a motion mode may be automatically implemented when movement of one or more components of the patient support apparatus occurs. In the transition mode, the exit detection system may use a least restrictive sensitivity level. In the motion mode, the exit detection system may inhibit exit alerts and/or change the criteria for issuing the exit alert.
