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 chair includes a seat, a backrest, and a leg rest. A tilt actuator and lift actuator tilt and lift the seat, respectively. A leg rest actuator extends and retracts the leg rest. A backrest actuator pivots the backrest with respect to the seat. A controller simultaneously controls the actuators such that they move sequentially between multiple predefined states. A control panel enables a user to automatically move the chair to any of the predefined states. Progress indicators are included that provide a visual indication of how far the chair has progressed to a commanded state. A controller controls the actuators such that they simultaneously arrive at each state. One or more functions on a control panel may also be automatically disabled and/or automatically enabled as the chair moves into or out of certain ones of the predefined states.

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 patient support system including a frame having first and second portions, at least one of them movable with respect to the other to transition the frame between a first configuration and a second configuration. A first port is coupled to the first portion of the frame, and a second port disposed with the second portion of the frame, such that a distance between the first port and the second port changes when the frame transitions between the first and second configurations. A fluid conduit is arranged between the first port and the second port and configured to transition between a first length and a second length, longer than the first length, when the frame is transitioned between the first and second configurations. The fluid conduit is configured with a resiliency to naturally return toward the first length. A method of using a patient support system is also included.

A pad assembly, system and method of securing a patient onto an operating table when the patient is in the Trendelenburg position. The pad assembly and system is used to support and hold a patient on a medical procedure table during a medical procedure performed while the table, and thus the patient lying thereon, is in an inclined position, such as the Trendelenburg position. The pad assembly and system has characteristics which promote improved securing to eliminate shifting and/or sliding due to gravitational forces when the patient's body is in the Trendelenburg position, as well as promote a secure holding of the patient in a desired position on the table, in order to minimize injury to the patient. The pad assembly and system further has improved channels to allow for drainage of fluids that may otherwise be trapped between the patient's body and the OR Table during the surgical procedure.

Person support apparatuses are disclosed. In one embodiment, a person support apparatus comprises a base frame and a primary support frame supported on the base frame. A carriage is freely translatable at least between a head end of the primary support frame and a foot end of the primary support frame. A support surface is supported on the carriage such that the support surface translates with the carriage. The support surface includes a support section which is collapsible in a length direction of the support surface. The support section may include an air bladder and a control valve fluidly coupled to the air bladder that regulates air pressure within the air bladder. The control valve has a normally closed position and a vent position, wherein the person support apparatus comprises an exercise configuration wherein the control valve is in the vent position and the air bladder is vented to atmosphere.

The object of the invention is the adjustable pedestal structure of the bed, by means of which the height and tilt positions of the sleeping platform structure can be adjusted. The pedestal structure consists of the three structural parts supported by the foot structure (30) equipped with wheels, the lower structural part (1a), the middle structural part (1b) and the upper structural part (1c), which consist of the rotation cylinders (2, 4, 6) acting as the adjustment mechanisms for the simultaneous or individual adjustment movements of the structural parts of the pedestal structure and the lever arms (3, 7, 5a) connected thereto and the axles (13a, 13b, 13c) connected to the ends of the lever arms to opposite ends of the rotation cylinders, around which the adjusting movements of the structural parts of the adjustable pedestal structure take place. The sleeping platform frame structure of the bed (31) is connected to the lever arms (5a) of the upper structural part (1c) of the pedestal structure.

This nursing bed has a fixed member forming a fixed bed surface of a bed portion on which a care receiver lies, a movable member which can be moved relative to the fixed member and forms a movable bed surface of the bed portion, and a movable member driving unit for driving the movable member. The fixed member has a plurality of slender parts each extending in the lateral direction or the longitudinal direction. The movable member has a mobile body which can be protruded upward relative to the fixed bed surface and also moved in at least one of the longitudinal direction and the lateral direction via an interval between the plurality of slender parts by the movable member driving unit. The posture of the care receiver lying on the bed can be changed into his/her optimal position without difficulty.
