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.

Load cell assembly for a patient support apparatus

A patient support system for providing customized user menus. The system comprises a patient support apparatus, a user interface configured to receive input from a user, and a display configured to display user menus or information. The user menus may comprise indicia representative of the operational functions of the patient support apparatus. A controller determines the customized user menu based on usage characteristics, a position of the user interface in proximity to the patient support apparatus, a location of the user interface within a facility, an identification of the user, and/or a patient condition. A touchscreen and/or a mobile device may comprise the user interface and the display. The mobile device may be removably coupled to the patient support apparatus. Methods for improving patient care by providing the customized user menu are also disclosed.

Patient support systems and methods for assisting caregivers with patient care

A person support apparatus, such as a bed, cot, stretcher, or the like, for a supporting an occupant includes an exit detection system that has, in some embodiments, multiple user-selectable zones. An alert is triggered when the occupant crosses a boundary of the selected zone. A first zone has a boundary that is adjusted based on a condition of the person support apparatus, such as the width of the support deck or other characteristic. A second zone has a boundary that is not adjusted based on the condition of the person support apparatus, but which may have a boundary that is dependent on an initial location of the occupant when the exit detection system is armed. The initial location of the occupant may correspond to a center of gravity of the occupant.

Person support apparatus with adjustable exit detection zones

A patient support apparatus including a support deck with a support surface and a deck section configured to move between a first position and a second position, a barrier to limit egress from the support surface operatively attached to the deck section for concurrent movement, and a user interface coupled to the barrier and configured to receive input from a user. The user interface includes a screen to display visual content to the user, and an input device to generate an input signal in response to receiving user input. An orientation sensor determines an orientation of the screen based on movement of the deck section between the first position and the second position. A controller is configured to perform a function in response to receiving the input signal, and maintain a predetermined orientation of the visual content displayed on the screen as the screen moves with the deck section.

Patient support apparatus control systems

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.

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.

Patient support apparatus with automatic exit detection modes of operation

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.

Person support apparatuses with load cells

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).

Patient support apparatus with multi-sensor fusion

A patient support apparatus, such as a bed, cot, stretcher, or the like, includes a litter frame, a support deck, a plurality of force sensors adapted to output signals corresponding to downward forces exerted on the support deck, and a controller configured carrying out various functions and to display various screens on a touchscreen or display, including a scale home screen and a scale equipment screen. A patient's current weight can be displayed on the scale home screen and the weight of equipment supported on the apparatus can be displayed on the scale home screen and the scale equipment screen. When a patient's current weight is characterized as possibly including non-patient weight, the controller can display a warning screen.

Patient support apparatus with equipment weight log

A patient support apparatus comprising a patient support deck, a touchscreen, and a controller. The patient support deck comprises a patient support surface. The touchscreen comprises a screen, an input surface arranged adjacent to the screen, and a touch sensor configured to generate an electric field within an envelope defined adjacent to the input surface to sense conductive objects interacting with the electric field. The touch sensor is operable at a first sensitivity level to detect conductive objects approaching the input surface, and a second sensitivity level to detect conductive objects engaging the input surface. The controller is in communication with the touchscreen to operate the touch sensor at the first sensitivity level during an absence of conductive objects interacting with the electric field, and to operate the touch sensor at the second sensitivity level in response to conductive objects interacting with the electric field within the envelope.
