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 includes a support structure including a base, an intermediate frame, and a patient support deck and a lift mechanism for moving the patient support deck relative to the base. A plurality of load cells are interposed between the lift mechanism and the support structure to measure load about the patient support surface. Each of the plurality of load cell assemblies includes a body, a bushing, and a shaft. The bushing is configured to be received by the body and defines opposing tapered regions and a central region. The shaft is configured to be received by the bushing and defines a reduced diameter region arranged to engage the central region of the bushing to urge the shaft into alignment with bushing and to permit limited pivoting and translational movement between the shaft and the bushing in response to load shifting between the plurality of load cell assemblies.

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, operating table, recliner, or the like, includes a patient support structure, a user interface, a display, and a controller. The user interface comprises a display and controls for configuring various components of the patient support apparatus. The patient support apparatus includes an exit detection system and a monitoring system, and each system may be separately armed and disarmed. The controller uses the display to issue one or more reminders to the caregiver to put the patient support apparatus in a desired configuration before the caregiver walks away from the patient support apparatus. Reminders may be ignored or dismissed. If a reminder is dismissed, the reminder is turned off for that patient and the corresponding system is disarmed. A caregiver may re-enable a reminder after it has been turned off.

Abstract: A patient support apparatus includes a support surface adapted to support a person, a display, a plurality of controls, a memory, and a controller. The controller is adapted to collect a batch of data regarding the operation of the patient support apparatus, to store the batch of data in the memory, to update the contents of the batch of data during usage of the patient support apparatus, and to display a coded image on the display in response to activation of a particular control. The coded image, which may be a QR code, encodes the batch of data. The encoded data may include sensor readings, diagnostic data, fault data, a serial number, and/or other data. The controller may also, or alternatively, display (either permanently or semi-permanently) the ward, department, floor, or another identifier (e.g. radiology, maternity, etc.) to which the patient support apparatus is assigned for a particular healthcare facility.

Abstract: A portable tool for communicating with an ultra-wideband (UWB) equipped patient support apparatus and/or a UWB-equipped locator unit. The tool may include a housing, a transceiver for communicating with a computer, a first (UWB) transceiver adapted to communicate with a second UWB transceiver, and a controller. The controller may be adapted to use the first UWB transceiver to obtain an identifier from the second UWB transceiver, and to determine whether the second UWB transceiver is positioned onboard a patient support apparatus or onboard a locator unit based on its identifier. If the second UWB transceiver is positioned onboard the patient support apparatus, the tool may determine a specific location of the second UWB transceiver onboard the patient support apparatus. The tool may alternatively be embodied in a software application adapted to be executed on a smart phone and/or personal computer.

Abstract: A thermal control system for controlling a patient's temperature includes a thermal control unit and an off-board computing device. The thermal control unit includes a fluid inlet, a fluid outlet, a pump, a heat exchanger, a display, one or more sensors, a transceiver, and a controller. The thermal control system employs one or more machine learning techniques to perform one or more of the following: automatically implement one or more user-preferred settings, automatically predict the occurrence of one or more events based on analyses of prior events, and/or automatically improve one or more algorithms based on analyses of additional sensor data. The machine learning techniques may be implemented onboard the thermal control unit and/or may be implemented at a remote computing device (e.g. a server) that collates and analyzes data from multiple thermal control units, and then sends the results of the analyses back to the thermal control units.

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.

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).
