An automated system and methods are provided for calibrating an accelerometer of a patient support apparatus using a load cell. The patient support apparatus includes a litter frame and a deck supported by the litter frame, movable between various angled positions. A patient support surface is arranged on the deck and configured to support a patient thereon. The patient support surface has at least one region configured to be disposed at an angular position. A load cell is provided, configured to generate load data including first and second load outputs detected at first and second trend angles with respect to a horizontal plane. An accelerometer is provided, configured to generate angle data including first and second angle outputs representative of the trend angles. A controller in communication with the load cell and the accelerometer determines an error in the angle data and calibrates the accelerometer.

A patient support apparatus, such as a bed, cot, stretcher, operating table, recliner, or the like, includes a litter frame, a support deck supported on the litter frame and adapted to support a mattress thereon, a touchscreen and a controller configured for carrying out various functions and to display various screens on the touchscreen, including screens for controlling a mattress therapy function or for controlling a non-mattress function of the patient support apparatus. A notification regarding the status of a mattress therapy function can be displayed on various screens. Status indications can be provided as a banner across a portion of the touchscreen.

A support apparatus for a person includes a main cushion having a bottom surface, a top surface to form a support surface for a person supported on the main cushion, and a length having a perimeter that has longitudinal and lateral sides extending around the perimeter. In addition, the support apparatus has at least one sleeve located along one of the sides of the man cushion. The sleeve is configured between a stowed state, where the sleeve is closely adjacent to the one side, and a deployed state, where the sleeve forms an extension of the top surface of the main cushion to thereby increase the width or the length of the support surface.

A power transfer system comprises a patient transport apparatus and a power transfer device. The power transfer system provides convenience and ease of connection between a power source and the patient transport apparatus to provide power to one or more electrically powered devices on the patient transport apparatus or to provide energy for an energy storage device on the patient transport apparatus.

A patient support apparatus includes a bed including a frame. A mattress is supported by the frame. A respiratory therapy apparatus is supported by the frame. A pneumatic system is operable to inflate at least one bladder of the mattress and operable to deliver air to the respiratory therapy apparatus.

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).

A patient support apparatus comprises a support structure. The support structure comprises a base and a patient support deck coupled to the base. The patient support deck comprises a patient support surface capable of articulating to adjust positioning of a patient supported thereon, a lift system configured to adjust a height of the patient support deck relative to the base, and a user interface system coupled to the support structure and comprising an elongated member and a user interface coupled to the elongated member. The user interface is configured to receive inputs from a user to control a function of the patient support apparatus.

The present disclosure relates to patient support systems, such as hospital beds, and particularly to reconfigurable patient support systems movable among a number of different positions. The present disclosure further relates to control algorithms and interfaces for use in patient support systems.

A system for use with a bed having a frame and a supporting surface includes a sheet having a bottom surface placed above the supporting surface of the bed, a top surface, and a plurality of tether straps connected to and extending from the sheet. Each tether strap is configured for connection to the bed. The bottom surface is at least partially formed of a low friction material, and the top surface is at least partially formed of a high friction material, such that the top surface provides greater slipping resistance than the bottom surface. The tether straps include at least two pairs of tether straps, with one pair connected proximate a top edge of the sheet and another pair connected proximate a bottom edge of the sheet. The sheet may further include a sliding member on the bottom surface to assist in lateral sliding of the sheet.

A patient support system comprises a patient support apparatus for patients. The patient support apparatus comprises a support structure and a patient support surface supported by the support structure. The patient support apparatus also comprises movable members. One or more rotary actuators are coupled to the movable members. The rotary actuator comprises a gear assembly with a cycloidal drive arranged to drive movement of the movable member. The gear assembly also restricts back drive torque from backdriving the movable member.
