A patient support apparatus system and patient support apparatus, such as a bed, cot, stretcher, operating table, recliner, or the like, include a litter frame, a support deck, a sensor configured to detect caregiver activity, a transceiver communicating with a server, and a controller. The controller is configured to send alerts or messages to the server when caregiver assignment errors or caregiver inattention issues are identified. An alert is sent when a caregiver has not attended to a patient within a certain period of time, or when a caregiver has not been assigned to a particular patient or a particular location within a healthcare facility to which a patient has been assigned. The patient support apparatus and system are in communication with other healthcare facility systems and devices that gather and share information and data to alert caregivers in an effort to avoid patient neglect.

A patient monitoring and repositioning system includes a mattress, a sheet residing on an upper surface of the mattress, a housing containing a drive mechanism, and a sensor adapted to sense a position of a patient resting on the mattress. The drive mechanism is operable to pull the sheet and thereby pull the patient resting thereon. The housing receives the sheet through a slot. In the event that the patient is in an undesirable position on the mattress as detected by the sensor, a controller directs the drive mechanism to pull the sheet so as to pull the patient thereon from the undesirable position to a desirable, predetermined position. The controller may direct the drive mechanism automatically or indicate the undesirable position to a caregiver so that the caregiver may direct the drive mechanism accordingly.

Energy harvesting and propulsion assistance techniques for a patient support apparatus are provided. The patient support apparatus comprises a base, a patient support surface supported by the base, and a powered device (e.g., propulsion device). An energy harvest and release system includes a harvesting device for harvesting energy, a storage device for storing and releasing the harvested energy, and a controller coupled to the harvesting device, the storage device, and the powered device. The controller is automated to selectively instruct the harvesting device to harvest energy and to selectively instruct release of the harvested energy from the storage device for consumption by the powered device (e.g., to assist in movement of the patient support apparatus).

A person support apparatus includes sensors for monitoring aspects of a person positioned thereon. The outputs from the sensors are used to distinguish between new and prior occupants of the support apparatus, automatically zero an integrated scale system, distinguish between objects and humans on the support apparatus, determine if a person is sleeping or awake, monitor and characterize movement levels of the person, record a log of likely events regarding a support surface of the apparatus, propose identifications of objects added to or removed from the support surface, record force outputs, and/or other purposes. A person's sleep state may also be obtained and forwarded to a remote location. The sleep state data may be used to mute and/or control alerts or indicators, and/or to predict when a person is going to wake up and likely exit the support apparatus.

A patient support system includes a scale system, an air system, and a lift system. The patient support system also includes a control system configured to graphically communicate information about the scale system, the air system, and the lift system to a user.

A method for controlling an angular orientation of a person support apparatus including a bladder portion containing fluidized particulate material, an upper frame, and a base frame may include adjusting a height of the upper frame with respect to the base frame with at least one of a first and second actuator at respective speeds, determining a dynamic angular orientation of the upper frame with respect to the base frame based on at least one of a respective operating characteristic of the first and second actuator, determining a corrected angular orientation based on the dynamic angular orientation and a floor angle indicative of the orientation of the base frame with respect to horizontal, comparing the corrected angular orientation with an orientation reference range, and adjusting at least one actuator speed when the corrected angular orientation is outside the orientation reference range until it is within the orientation reference range.

A patient support apparatus comprises a base supported by caster assemblies with each caster assembly comprising a stem, a caster wheel, and a caster wheel axle. A patient support surface is coupled to the base and is configured to receive a load. One or more load sensors are integrated with at least one of the stem, the caster wheel, or the caster wheel axle for measuring the load. One or more of the caster assemblies can be coupled to a steering motor, which controls orientation of the caster assembly. A controller can control the steering motors based on analyzing the measurements of the load sensor. The load sensors can produce measurements indicative of both vertical load and non-vertical load applied to the caster assembly. The controller can also analyze the measurements of the load sensor to determine the load received by the patient support surface by negating the non-vertical load.

A bed system including an acquisition unit and a display, in which the acquisition unit acquires user interface device information from a plurality of user interface devices and the display displays a plurality of images corresponding respectively to the plurality of user interface devices on a single screen based on the user interface device information. One set of the plurality of user interface device information includes state information including at least one of bed state information relating to the state of one bed among a plurality of beds and user state information relating to the state of a user of the one bed among the plurality of beds. One image among the plurality of images includes a state display corresponding to the state information. When the state information is abnormal, the first display displays a warning display on the one image among the plurality of images.

A person support apparatus includes sensors for monitoring aspects of a person positioned thereon. The outputs from the sensors are used to distinguish between new and prior occupants of the support apparatus, automatically zero an integrated scale system, distinguish between objects and humans on the support apparatus, determine if a person is sleeping or awake, monitor and characterize movement levels of the person, record a log of likely events regarding a support surface of the apparatus, propose identifications of objects added to or removed from the support surface, record force outputs, and/or other purposes. A person's sleep state may also be obtained and forwarded to a remote location. The sleep state data may be used to mute and/or control alerts or indicators, and/or to predict when a person is going to wake up and likely exit the support apparatus.

A hospital bed height limiting system comprising a processing unit operatively connected to each of a user interface, an elevation mechanism of the hospital bed and a height sensor. The processing unit is operable to receive a minimum height via the user interface and receive from the height sensor a current elevation mechanism height. The processing unit is operable to determine the bed height based on the current elevation mechanism height, and in response to the bed height being equal to the minimum height, the processing unit is operable to cause the elevation mechanism to stop a downward movement of the elevation mechanism. A hospital bed comprising the hospital bed height limiting system is also provided.
