Patient support apparatuses, such as beds, cots, stretchers, recliners, or the like, include control systems with one or more image, radar, and/or laser sensors to detect objects and determine if a likelihood of collision exists. If so, the control system controls the speed and steering of the patient support apparatus in order to reduce the likelihood of collision. The control system may be adapted to autonomously drive the patient support apparatus, to transmit a message to a remote device indicating whether it is occupied by a patient or not, and/or to transmit its route to the remote device. The remote device may determine an estimate of a time of arrival of the patient support apparatus at a particular destination and/or determine a distance of the patient support apparatus from the particular destination.

A patient transport apparatus transports a patient over a surface. The patient transport apparatus comprises a base and support wheels coupled to the base. An auxiliary wheel assembly is coupled to the base and comprises one or more auxiliary wheels that influence motion of the patient transport apparatus over the surface to assist caregivers. An actuator system is operatively coupled to the auxiliary wheels to move the auxiliary wheels relative to the base from a stowed position to a first deployed position, and further to a second deployed position.

Powered patient support apparatuses—such as beds, cots, stretchers, or the like—include a plurality of user controls that allow a caregiver to control the steering and/or driving of one or more powered wheels from multiple different locations around the patient support apparatus (e.g. head end, foot end, and/or the sides). The control is carried out by force sensors that detect both an orientation of the applied forces and a magnitude of the applied forces. Translational and/or rotational movement is effectuated, depending upon the magnitude and direction of the forces, as well as the physical location of the applied force relative to a reference point on the support apparatus, such as the center. One or more object sensors may also be included in the support apparatus to assist in steering and/or navigating.

A caregiver assistance system is disclosed for helping caregivers manage the care of existing bed sores and/or reduce the risk of a patient developing bed sores. The system may also help the caregiver to perform rounding tasks and/or to reduce the likelihood of patient falls. The system comprises a server application in communication with the patient's bed and one or more mobile electronic devices (e.g. smart phones). The mobile devices receive individual assessments of a plurality of bed sore risk factors and forward them to the server. The server generates bed sore risk scores from the answers and forward them to an EMR server. The server may also determine one or more risk reduction steps, display them on the mobile electronic device, and/or forward them to the patients' beds for implementation thereon. Additional bed sore information may be captured and sent to the EMR.

A person support apparatus with an extendable mattress, a night light message display system, a screen key pendant, egress handle siderails, and various other features. The extendable mattress includes hinged extensions along the sides of the extendable mattress that are moved from a nested position to the extension position. The screen key pendant includes a plurality of screen keys that can be pressed to cycle through various control modes for the person support apparatus. The night light message display system can be configured to display a message or image on the floor communicating information to the person and/or alerting the person as to when they are able to exit the bed.

A caregiver assistance system is disclosed for assisting a caregiver to ensure the beds of high fall risk patients are in desired states for reducing the likelihood of a patient falling. The system may also help the caregiver to perform rounding tasks. The system comprises a server in communication with the patients' beds and one or more mobile electronic devices (e.g. smart phones). The mobile devices receive answers to a plurality of fall risk questions and forward them to the server. The server generates a patient fall risk assessment from the answers, determines a desired state for fall-risk components of the bed if the patient fall risk assessment indicates the patient has a high risk of falling, compares the states of the fall-risk components to corresponding desired states, and issues an alert at the mobile device if any of the fall-risk components are not in their desired state.

Systems and methods for a load sensing system that determines a mass on a bed. The systems generally are in the form of a castor base, particularly one that can be used as part of an adjustable hospital bed. The load sensing system serves to determine the mass of any object or objects (typically a human or animal patient) which is placed on the bed by having the mass create a force on lever arms of a plurality of load cells in the castor base. The load sensing systems are designed to work without hindering the adjustable functionality of the bed and can accurately determine mass (weight) at any position of the bed, and potentially even while the bed is adjusting between positions.

A patient support apparatus includes a frame, wheels, a patient support surface, a motor, a power assist control, a sensor, and a controller. The power assist control detects a force applied to it. The sensor detects an angular orientation of the patient support apparatus with respect to a generally horizontal plane. The controller drives the motor at different levels for a particular force applied to the power assist control depending upon the angular orientation sensed by the sensor. The controller may control the motors such that the patient support apparatus accelerates at substantially the same rate, regardless of the angle of the patient support apparatus. The controller may also limit the driving of the motor to less than a maximum value based upon the angular orientation of the patient support apparatus.

A power transfer system comprises a patient support apparatus and a separate power transfer device. The patient support apparatus comprises a support structure having a base and a patient support surface for a patient and wheels coupled to the support structure to facilitate movement of the patient support apparatus over a floor surface. One or more of the wheels includes a power receiver integrated therewith. The power transfer device is energizeable to interact with the wheel to facilitate power transfer between the power transfer device and the power receiver through the wheel.

Systems for facilitating movement of a patient transport apparatus are provided and include user input control device that includes a mode switch selectable between a longitudinal transport mode and a multidirectional mode and a driving assist device actuatable between at least one engaged state and a non-engaged state. The mode switch generates signals based on the selected mode and the driving assist device generates engaged or non-engaged signals which are received by a controller. The controller is configured to generate an output signal sent to a lift actuator, swivel actuator, and/or a powered drive system to assist a user in propelling the apparatus in a desired manner.
