Abstract

A pendant controller for a patient bed includes a housing sized to be held in a user'"'"'s hand and a liquid crystal display carried by the housing and viewable by the user. The pendant controller has a set of manual buttons carried by the housing adjacent the LCD. The set of manual buttons is arranged in a row and the buttons are n in number, with n being an integer greater than 1. The pendant controller further includes control circuitry situated in the housing and configured to drive the LCD to display a table that is m columns wide, with m being equal to n. The table contains indicia with each indicia corresponding to a function associated with a respective one of the manual buttons.

Claims

1. A pendant controller for a patient bed, the pendant controller comprising

a housing sized to be held in a user'"'"'s hand,

a liquid crystal display carried by the housing and viewable by the user,

a set of manual buttons carried by the housing adjacent the LCD, the set of manual buttons being arranged in a row and being n in number, wherein n is an integer greater than 1, and

control circuitry situated in the housing and configured to drive the LCD to display a table that is m columns wide, wherein m is equal to n, and the table contains indicia with each indicia corresponding to a function associated with a respective one of the manual buttons.

2. The pendant controller of claim 1, further comprising an electrical cable coupled to the housing and extending from the housing to the patient bed.

3. The pendant controller of claim 1, wherein the housing is coupleable to a siderail of the patient bed.

4. The pendant controller of claim 1, wherein an angle at which a head section of the patient bed is inclined is displayed on the LCD when the LCD is in a default condition.

5. The pendant controller of claim 1, wherein n and m are at least equal to four such that the set of manual buttons includes a first button, a second button, a third button and a fourth button.

6. The pendant controller of claim 5, wherein the control circuitry is configured such that pressing the second button results in the table changing from a home table setting to a scale table setting, the control circuitry is configured such that pressing the third button results in the table changing from the home table setting to a patient position monitor table setting, and the control circuitry is configured such that pressing the fourth button results in the table changing from the home table setting to a surface table setting.

7. The pendant controller of claim 6, wherein the scale table setting includes a home indicia adjacent the first button, a weigh indicia adjacent the second button, a calibration indicia adjacent the third button, and a history indicia adjacent the fourth button.

8. The pendant controller of claim 7, wherein the control circuitry is configured such that, when the scale table setting is displayed on the LCD, pressing the first button results in the scale table setting changing back to the home table setting, pressing the second button results in a weight of a patient on the patient bed being displayed on the LCD, pressing the third button results in the table changing from the scale table setting to a scale calibration table setting, and pressing the fourth button results in weight history information being displayed on the LCD.

9. The pendant controller of claim 8, wherein the weight history information includes the date at which the scale system was last calibrated, the time at which the scale system was last calibrated, and the last weight reading that the scale system took.

10. The pendant controller of claim 8, wherein the control circuitry is configured such that, when the scale calibration setting is displayed on the LCD, pressing the first button results in the table changing from the scale calibration setting back to the scale table setting, pressing the second button results in a weight of the patient on the patient bed being displayed on the LCD, pressing the third button results in the table changing to a plus/minus table setting in which one of the manual buttons is used to calibrate a scale system of the patient bed by adding a weight offset and another of the manual buttons is used to calibrate the scale system of the patient bed by subtracting a weight offset, and pressing the fourth button results in the scale system of the bed being zeroed.

11. The pendant controller of claim 6, wherein the patient position monitor table setting includes a home indicia adjacent the first button, a position indicia adjacent the second button, an exiting indicia adjacent the third button, and an out-of-bed indicia adjacent the fourth button.

12. The pendant controller of claim 11, wherein the control circuitry is configured such that, when the patient position monitor table setting is displayed on the LCD, pressing the first button results in the patient position monitor table setting changing back to the home table setting;

sequential presses of the second button results in a patient position monitoring system of the patient bed being sequentially enabled and disabled in a patient position mode;

sequential presses of the third button results in the patient position monitoring system of the patient bed being sequentially enabled and disabled in an exiting mode; and

sequential presses of the fourth button results in the patient position monitoring system of the patient bed being sequentially enabled and disabled in an out-of-bed mode.

13. The pendant controller of claim 6, wherein the surface table setting includes a home indicia adjacent the first button, a select indicia adjacent the second button, an up indicia adjacent the third button, and a down indicia adjacent the fourth button.

14. The pendant controller of claim 13, wherein the control circuitry is configured such that, when the surface table setting is displayed on the LCD, pressing the first button results in the scale table setting changing back to the home table setting;

sequential presses of the second button results in sequential scrolling through a set of mattress zone indicia shown on the LCD to indicate which mattress zone of an air mattress of the patient bed is selected for pressure adjustment;

pressing the third button results in a target pressure increase for the mattress zone selected using the second button; and

pressing the fourth button results in a target pressure decrease for the mattress zone selected using the second button.

15. The pendant controller of claim 14, wherein the mattress zone indicia comprise first, second, and third mattress zone indicia.

16. The pendant controller of claim 15, wherein a first, second, and third zone pressure numeral is shown on the LCD adjacent the respective first, second, and third mattress zone indicia.

17. The pendant controller of claim 16, wherein the first, second, and third zone pressure numerals each represent a percent amount that the respective zone is pressurized toward a maximum pressure.

18. The pendant controller of claim 6, wherein the control circuitry is configured such that if the scale table setting, patient position monitor table setting or surface table setting is shown on the LCD for a threshold amount of time without any of the first, second, third, or fourth buttons being pressed, the home table setting will be displayed on the table.
