Abstract

A patient support apparatus is provided. The patient support apparatus includes a plurality of therapeutic devices including a rotation device and a percussion-vibration device for carrying out rotation, percussion, and vibration therapy for a patient. The patient support apparatus includes a control system for controlling operation of the plurality of therapeutic devices. The control system comprises a touch-screen display segmented into a main menu portion and a data window portion. The therapeutic functions are represented by touch selectable buttons on the main menu portion. When any of these buttons are selected, a plurality of adjustable operating parameters appears in the data window portion. At the same time, the buttons corresponding to the therapeutic functions in the main menu portion remain visible such that an operator can easily select another therapeutic function. A method of tracking the therapeutic functions performed is provided. A rotation monitoring system and temperature control system of the patient support apparatus are provided. A display activation system is also provided.

said touch selectable buttons being continuously displayed on said touch-screen display before and after operator selection thereof such that an operator can easily select between each of said plurality of therapeutic functions.

2. A patient support apparatus as set forth in claim 1 wherein said plurality of therapeutic functions includes a rotation function, percussion function, and vibration function.

3. A patient support apparatus as set forth in claim 2 wherein said mattress includes a rotation device and a percussion-vibration device for carrying out said plurality of therapeutic functions.

4. A patient support apparatus as set forth in claim 2 wherein said main menu portion of said touch-screen display further includes a touch selectable button configured to selectively start each of said plurality of therapeutic functions after setting said at least one adjustable operating parameter.

5. A patient support apparatus as set forth in claim 4 wherein said main menu portion of said touch-screen display further includes a touch selectable button configured to selectively stop each of said plurality of therapeutic functions during operation thereof wherein said stop button is present in said main menu portion at all times during operation of said therapeutic functions.

6. A patient support apparatus as set forth in claim 2 wherein said at least one adjustable operating parameter for said rotation function includes a right side rotation angle, a left side rotation angle, a right side hold time, a left side hold time, a center hold time, and a total rotation time.

7. A patient support apparatus as set forth in claim 2 wherein said at least one adjustable operating parameter for said percussion function includes an intensity level, a frequency, a total percussion time, and an application zone.

8. A patient support apparatus as set forth in claim 2 wherein said at least one adjustable operating parameter for said vibration function includes an intensity level, a total vibration time, and an application zone.

9. patient support apparatus as set forth in claim 1 wherein said mattress further includes a firmness setting device for carrying out a firmness setting function.

10. A patient support apparatus as set forth in claim 9 wherein said at least one adjustable operating parameter for said firmness setting function includes a firmness level.

11. A patient support apparatus as set forth in claim 1 wherein said mattress includes at least one air bladder and said main menu portion of said touch-screen display includes a touch selectable button corresponding to a maximum inflation function and said control system is configured to automatically inflate said at least one air bladder to a maximum pressure upon operator selection thereof.

12. A patient support apparatus as set forth in claim 1 wherein said mattress includes a rotation device and said main menu portion of said touch-screen display includes a touch selectable button corresponding to a patient turning function and said data window portion includes a pair of touch selectable buttons corresponding to a left turn or a right turn of said patient upon operator selection of said touch selectable button corresponding to said patient turning function.

13. A patient support apparatus as set forth in claim 1 wherein said main menu portion includes a touch selectable button corresponding to a silence alarm function and said control system is configured to automatically discontinue all alarms upon operator selection thereof.

14. A patient support apparatus as set forth in claim 1 wherein said main menu portion includes a touch selectable button corresponding to advanced functions including a language function, a reset function, a set alarm type function, and a therapy history.

15. A patient support apparatus as set forth in claim 1 including a pendant rotatably mounted to said mattress wherein said touch-screen display is attached to said pendant for rotation with said pendant relative to said mattress to facilitate viewing by users of said touch-screen display.

16. A method of tracking a therapeutic function conducted by a patient support apparatus, comprising the steps of;

selecting a therapeutic function of the patient support apparatus,

adjusting at least one operating parameter associated with the therapeutic function,

starting operation of the therapeutic function after selecting the therapeutic function and adjusting the at least one operating parameter,

logging the operation of the therapeutic function in a retrievable electronic storage format, and

displaying the logged operation of the therapeutic function in predetermined time increments.

17. A method as set forth in claim 16 further comprising the steps of:

selecting a second therapeutic function of the patient support apparatus,

starting operation of the second therapeutic function,

logging the operation of the second therapeutic function in the retrievable electronic storage format, and

displaying the logged operation of each of the therapeutic functions in rolling 12-hour and 24-hour increments.

18. A patient support apparatus having a rotation monitoring system, comprising;

a mattress having a main body portion and a head end portion extending from said main body portion and adjustable between a plurality of angular positions relative to a horizontal reference,

an angle sensor responsive to adjustment of said head end portion between said plurality of angular positions relative to said horizontal reference,

a rotation device disposed in said mattress for providing rotation therapy to a patient, and

a control system in operative communication with said angle sensor and said rotation device and configured for determining the angular position of said head end portion relative to said horizontal reference and restricting said rotation device to rotating the patient through a predetermined moderate rotation range in response to the angular position falling within a predetermined range.

19. A patient support apparatus as set forth in claim 18 wherein said predetermined moderate rotation range is from 15 to 25 degrees of rotation when the predetermined range of said angular positions relative to said horizontal reference is from 30 to 60 degrees.
