A patient support apparatus includes a load frame, a support frame, and a plurality of load cells supporting the load frame on the support frame such that a load supported by the load frame is supported by the load cells, each load cell configured to produce a signal indicative of a load weight bearing upon that load cell. The load cells are calibrated after installation.

A person support apparatus includes one or more thermal image sensors whose outputs are analyzed to perform one or more functions. Such functions include automatically turning on a brake, automatically turning on one or more lights, detecting when a patient associated with the person support apparatus has fallen, enabling a propulsion system of the patient support apparatus to be used, automatically controlling one or more environmental controls, and/or automatically arming an exit detection system after entry of a patient onto the person support apparatus. Multiple thermal images may be generated from multiple sensors to generate stereoscopic thermal images of portions of the person support apparatus and its surroundings.

A patient turning device for a patient support apparatus. The patient turning device includes a first and second bladder assembly each including a plurality of layers and seals defining a bladder volume. The bladder volumes are selectively inflatable with fluid to expand the respective bladder assembly, and consequently move a patient support surface of the patient support apparatus. A portion of a lower layer of the first bladder assembly and a portion of an upper layer of the second bladder assembly define an overlapping region of the bladder volumes. The patient turning device is coupled to an underside of a carrier sheet and positioned between a crib assembly and a bottom cover. An augmenting feature is configured to resiliently expand as at least one of the first and second bladder assemblies receives the fluid to move at least a portion of the crib assembly away from a patient support deck.

A braking system for a patient support apparatus includes a caster wheel assembly. The caster wheel assembly includes a caster wheel and manually operable brake operable to brake the caster wheel. The caster wheel assembly further includes a manual brake activation handle or pedal for manually operating the manually operable brake to move between three positions, wherein said three positions include a braking position, an un-braked position, and a steer lock position. The braking system further includes an electrically powered actuator mechanically coupled to the manual brake activation handle or pedal and to the manually operable brake. When powered, the electrically powered actuator is operable to move the manually operable brake and to move the manual brake activation handle or pedal between two or more of the three positions to thereby manually operate the caster wheel in a braking mode, an un-braked mode, or a steer lock mode. And, when the actuator is unpowered, the manual brake activation handle or pedal is operable to be manually moved between two or more of the three positions to thereby manually operate the caster wheel in the braking mode, the un-braked mode, or the steer lock mode.

An adjustable bed having a mattress support platform and a fixed frame base with wheels. A lift mechanism interconnects the mattress support platform and the fixed frame base to displace the mattress support platform between a fully collapsed position and a fully elevated position. The lift mechanism includes leg members pivotally connected with the fixed frame base and with the mattress support platform. A force multiplying actuating linkage interconnects an actuator and the fixed frame base. The actuating linkage includes a driving link and an intermediate link. The driving link has a first end pivotally mounted to the fixed frame base and a second end pivotally connected to the actuator. The intermediate link is pivotally connected to the driving link, and is pivotally engaged with one of the leg members and a stabilizing link. The stabilizing link interconnects one of the leg members and the fixed frame base.

A patient support apparatus comprising a patient support deck and a base to support the patient support deck from a ground surface, with a first frame assembly comprising a plurality of wheels to facilitate movement of the base, and a second frame assembly with one or more lift arms coupling the base to the second frame assembly. A load cell assembly to sense weight applied to the first frame assembly by the second frame assembly comprises a load cell support assembly coupled to the first frame assembly, and a load cell element coupled to the second frame assembly and mounted onto the load cell support assembly such that the second frame assembly is movable with respect to the first frame assembly along two axes of translation and is pivotable with respect to the first frame assembly about three axes of rotation.

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 patient support apparatus, such as a bed, cot, stretcher, operating table, recliner, or the like, includes a litter frame, a support deck, a user interface having a touchscreen and a controller configured carrying out various functions and to display various screens on the touchscreen. When user input to control the litter frame or support deck is received, the controller is configured to add a numeric indicator representative of the position of the litter frame or support deck to the screen. When a user input to carry out a function for which the apparatus is not in an acceptable state, the controller is configured to notify the user of this error and provide a control for remedying the error on the touchscreen. The controller is further configured to provide multiple levels of help information on the screen.

A patient support apparatus includes a frame, support surface, cable interface, switches, a location detector, and a controller. The switches are electrically coupled to the interface and the controller selects a configuration for the plurality of switches based on a current location of the patient support apparatus within a healthcare facility. Alternatively or additionally, a user interface may display a plurality of identifiers that each identifies a predefined configuration for the switches wherein the controller configures the switches according to an identifier selected by the user. A transceiver on board the patient support apparatus may communicate with different fixed transmitters and the controller may implement different switch configurations based on messages from the different fixed transmitters.

A bed includes: a bed body having a space for a user to rest; a monitoring device connected to the bed body, the monitoring device including a pressure detecting mechanism, a signal processing unit electrically coupled to the pressure detecting mechanism, and a monitoring unit electrically coupled to the signal processing unit. The pressure detecting mechanism is configured to detect pressure variations of the bed body, generate pressure data, and transmit the pressure data to the signal processing unit. The signal processing unit is configured to process the pressure data and generate processed signal data. The monitoring unit is configured to monitor the processed signal data.
