Abstract

A hospital bed including a mattress and a frame. The width of the frame of the hospital bed is adjustable and the width of the mattress is adjustable. The hospital bed may include a frame and mattress adapted to support a heavy or large patient, including a bariatric or obese patient.

Claims

1. A control system for a patient support, including a mattress having an identifying feature, comprising:

an input device, to receive a first input representative of a first identifying feature, to receive a second input representative of a second identifying feature, and to generate a first signal in response to the first input and a second signal in response to the second input, wherein the first identifying feature corresponds to a foam mattress type and the second identifying feature corresponds to an air mattress type; and

a controller, coupled to the input device, to receive the first signal and the second signal, the controller including a plurality of selectable outputs, to select a portion of the selectable outputs in response to the received first signal, and

a display operably coupled to the controller, to display a first screen in response to the received first signal and to display a second screen in response to the received second signal, wherein the first screen comprises a first selectable function and the second screen comprises a second selectable function different than the first selectable function.

2. The control system of claim 1, wherein the controller selects all of the selectable outputs in response to the received second signal.

3. The control system of claim 2, wherein the input device comprises a user accessible input device.

4. The control system of claim 3, wherein the user accessible input device comprises a screen to view indicia of the first identifying feature and the second identifying feature.

5. The control system of claim 4, wherein the mattress includes a first side having a first width adjustment bladder coupled thereto.

6. The control system of claim 5, further comprising a first valve coupled to the controller and to the portion of the selectable outputs to inflate the first width adjustment bladder.

7. The control system of claim 6, wherein the mattress includes a second side, having a second width adjustment bladder coupled thereto.

8. The control system of claim 7, further comprising a second valve coupled to the controller, wherein the second valve is coupled to the portion of the selectable outputs to inflate the second width adjustment bladder.

9. The control system of claim 4, wherein the mattress includes a first side having a first width adjustment bladder coupled thereto and a second side having a second width adjustment bladder coupled thereto.

10. The control system of claim 9, further comprising a first valve coupled to the first width adjustment bladder and the second width adjustment bladder.

11. The control system of claim 1, wherein the patient support comprises a frame supporting the mattress, the controller controls features of the frame and the mattress, and the input device comprises a sensing device.

12. The control system of claim 1, wherein the patient support comprises a frame supporting the mattress and the controller controls features of the frame and the mattress, further comprising a first valve configured to inflate a first width adjustment bladder coupled to the mattress in response to the controller selecting at least one of the plurality of outputs.

13. The control system of claim 12, wherein the controller controls the first valve in response to receiving the second signal.

14. The control system of claim 1, wherein the patient support comprises a frame supporting the mattress and the controller controls features of the frame and the mattress, wherein the input device is configured to be activatable by a user to initiate a control signal.

15. The control system of claim 14, wherein the controller is operable to adjust a width of the patient support by selecting at least one of the plurality of outputs corresponding to adjustment of the width of the patient support.

16. The control system of claim 15, wherein the controller is operable to adjust a length of the patient support by selecting at least another one of the plurality of outputs corresponding to adjustment of the length of the patient support.

17. The control system of claim 16, wherein the mattress has at least a head section, a seat section, and a foot section, and the controller is operable to at least partially deflate at least one bladder of the seat section of the mattress.

18. The control system of claim 14, further comprising a display operably coupled to the controller, the display configured to display a visual aspect of the input device activated by the user and to display information relating to the control signal.
