Abstract

A patient handling device includes a frame for supporting a patient, a controller, and two alert lights which are activated when a controller detects an alert situation, such as, but not limited to, a patient exiting from the patient handling device. The controller is in communication with the alert lights and operable to monitor an integrated bed exit system. The alert lights are positioned adjacent the foot end corners of the frame and are viewable by a user positioned anywhere within a 270 degree section of a circle defined at the center of the patient handling device. The alert lights include one or more Light Emitting Diodes (LEDs).

First claim

What is claimed is:

1. A bed comprising:
a frame adapted to support a mattress and a patient;
a plurality of bed components including a deck section supported by said frame, a siderail, a caster brake and a lift assembly to raise said frame; and
a bed exit system adapted to detect when a patient exits the bed and adapted to issue an alert when the bed exit system is in an armed state and a patient exits the bed, the bed exit system adapted to not issue an alert when the bed exit system is in a disarmed state and the patient exits the bed;
a controller adapted to detect a state of each of the bed components of said plurality of bed components;
a plurality of Light Emitting Diodes (LEDs) at a foot end of the bed, a first set of the LEDs adapted to emit light of a first color and a second set of the plurality of LEDs adapted to emit light of a second color different from the first color, the first set of LEDs not including any LEDs from the second set of LEDs; and
said controller adapted to activate the first set of LEDs to emit light in the first color and not activate the second set of LEDs to emit light in the second color in response to all of the following conditions being true: (a) the bed exit system is armed, (b) a first bed component of the plurality of bed components is in a desired first state, and (c) a second component of the plurality of bed components is in a desired second state to thereby provide a unified indication that the bed is in a desired configuration; the controller further adapted to not activate the first set of LEDs to emit light in the first color and to activate the second set of LEDs to emit light in the second color in response to any of the following conditions being true: (d) the bed exit system is disarmed, (e) the first component is not in the desired first state, or (f) the second component is not in the desired second state, to thereby provide a unified indication that the bed is not in a desired configuration.

2. The bed of claim 1 further comprising a display, wherein the controller is adapted to provide a first graphical indication on the display when the first component is not in the desired first state, to provide a second graphical indication on the display when the second component is not in the desired second state, and to provide a third graphical indication on the display when the bed exit system is disarmed.

3. The bed of claim 1 further comprising an annunciator comprising a first light, a second light, a third light, a first message, a second message, and a third message, and wherein the controller is further adapted to illuminate the first message via the first light when the first component is in the desired first state, to illuminate the second message via the second light when the second component is in the desired second state, and to illuminate the third message via the third light when the bed exit system detects the patient exits the bed.

4. The bed of claim 1 wherein the second set of LEDs includes a first LED positioned adjacent a first corner of the foot end of the frame and a second LED positioned adjacent a second corner of the foot end of the frame opposite the first corner.

5. The bed of claim 1 wherein the first component is the caster brake, further comprising a brake sensor, wherein said controller detects the state of the caster brake with the brake sensor, and the desired first state is the brake being activated.

6. The bed of claim 5 wherein the frame is an adjustable height frame, the second component is the adjustable height frame, and the desired second state is the adjustable height frame being at or below a specific height.

7. The bed of claim 5 wherein the siderail is adapted to be moved between a raised position and a lowered position, wherein the second component is the siderail, further comprising a siderail sensor, and the desired second state is the siderail being in the raised position.

8. The bed of claim 1 wherein the first color is green and the second color is amber.

9. The bed of claim 1 wherein the deck includes a head section pivotable to different orientations and a deck angle sensor adapted to detect an angle of the head section, wherein the first component is the head section of the deck, and the desired first state is a state in which the head section is pivoted above a threshold angle.
