Abstract
Patient handling equipment, such as a hospital bed, is provided with a propulsion system and a status indicator light system incorporated in the propulsion system and operable to generate at least two light beams beyond a perimeter of the bed. The light indicator, which may have different colors, shapes or intensities, can indicate the state of propulsion of the system and generates light beams which are visible all around the equipment so as to be visible to a carer from any angle. The apparatus may include an ambient light sensor disposed to detect floor level lighting conditions rather than general ambient light.
Claims29
A medical bed comprising:
- a chassis;
- a plurality of castor wheels coupled to the chassis;
- a propulsion system for driving the medical bed, the propulsion system comprising at least one drive wheel configured to be raised to disengage from a floor on which the medical bed is positioned and lowered to engage the floor on which the medical bed is positioned;
- and
- a status light indicator device operatively associated with the propulsion system and generating light to provide an indicator as to a state of at least one of the propulsion system and a component thereof.
A medical bed comprising:
- a chassis;
- a plurality of castor wheels coupled to the chassis;
- a propulsion system for driving the medical bed, the propulsion system comprising at least one drive wheel configured to be raised to disengage from a floor on which the medical bed is positioned and lowered to engage the floor on which the medical bed is positioned;
- a brake pedal configured to apply a braking force to the plurality of castor wheels and in communication with the propulsion system;
- and
- a status light indicator device operatively associated with the propulsion system,
- wherein the status light indicator device is mounted to one of:
- a lower surface of the chassis adjacent to the propulsion system;
- a lower surface of the medical bed adjacent to the propulsion system;
- and directly mounted to the propulsion system, and
- wherein the drive wheel is raised when the brake pedal is positioned such that the braking force is applied to the plurality of castor wheels.
A medical bed comprising:
- a chassis;
- a plurality of castor wheels coupled to the chassis;
- a propulsion system for driving the medical bed, the propulsion system comprising at least one drive wheel configured to be raised to disengage from a floor on which the medical bed is positioned and lowered to engage the floor on which the medical bed is positioned;
- a foot pedal in communication with the propulsion system;
- an ambient light sensor;
- and
- a status light indicator device operatively associated with the propulsion system and the ambient light sensor,
- wherein the status light indicator device adjusts an intensity of light generated by the status light indicator device based on detected ambient light intensity, and
- wherein the drive wheel is raised or lowered based on a position of the foot pedal.
