MEDICAL SUPPORT APPARATUS

摘要

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.

1. A chair comprising:
a base; a seat supported on the base; a backrest pivotable to different angular orientations with respect to the base; a leg rest extendible and retractable to different positions with respect to the seat; a controller for moving the chair from a first state to a second state, the first state being defined by a first orientation of the backrest and a first position of the leg rest, and the second state being defined by a second orientation of the backrest and a second position of the leg rest; and a control panel in communication with the controller, the control panel adapted to allow a user to move the chair from the first state to the second state, the control panel comprising a visual indicator that provides a visual indication of how far the chair has progressed when moving from the first state to the second state.
