Abstract

A patient support apparatus including a support deck with a support surface and a deck section configured to move between a first position and a second position, a barrier to limit egress from the support surface operatively attached to the deck section for concurrent movement, and a user interface coupled to the barrier and configured to receive input from a user. The user interface includes a screen to display visual content to the user, and an input device to generate an input signal in response to receiving user input. An orientation sensor determines an orientation of the screen based on movement of the deck section between the first position and the second position. A controller is configured to perform a function in response to receiving the input signal, and maintain a predetermined orientation of the visual content displayed on the screen as the screen moves with the deck section.

First claim

What is claimed is:

1. A patient support apparatus comprising:
a patient support deck comprising a patient support surface and a deck section configured to move between a first section position and a second section position;
a barrier to at least partially limit patient egress from the patient support surface, the barrier being operatively attached to the deck section of the patient support deck for concurrent movement between the first section position and the second section position;
a user interface coupled to the barrier and configured to receive input from a user, the user interface including a screen to display visual content to the user, and an input device to generate an input signal in response to receiving user input;
an orientation sensor to determine an orientation of the screen of the user interface based on movement of the deck section between the first section position and the second section position; and
a controller in communication with the user interface and the orientation sensor, the controller being configured to:
perform a function of the patient support apparatus in response to receiving the input signal from the input device; and
maintain a predetermined orientation of the visual content displayed on the screen based on the orientation of the screen determined by the orientation sensor as the screen moves with the deck section between the first section position and the second section position.

2. The patient support apparatus as set forth in claim 1 , wherein the input device of the user interface includes a control element arranged to receive tactile input from the user.

3. The patient support apparatus as set forth in claim 2 , wherein the control element has a round profile.

4. The patient support apparatus as set forth in claim 1 , wherein the input device of the user interface includes an inertial sensor.

5. The patient support apparatus as set forth in claim 4 , wherein the inertial sensor comprises an accelerometer.

6. The patient support apparatus as set forth in claim 4 , wherein the inertial sensor comprises a gyroscope.

7. The patient support apparatus as set forth in claim 1 , wherein the input device of the user interface includes a control element arranged for rotational movement about a control element axis.

8. The patient support apparatus as set forth in claim 1 , wherein the input device of the user interface includes a control element arranged for pivotal movement about a control element axis.

9. The patient support apparatus as set forth in claim 1 , wherein the input device of the user interface includes control element is arranged for translation along a control element axis.

10. The patient support apparatus as set forth in claim 9 , wherein the controller is configured to facilitate navigation of the visual content in response to receiving the input signal from the input device.

11. The patient support apparatus as set forth in claim 1 , wherein the orientation sensor comprises a potentiometer.

12. The patient support apparatus as set forth in claim 1 , wherein the orientation sensor comprises an accelerometer.

13. The patient support apparatus as set forth in claim 1 , wherein the orientation sensor comprises a gyroscope.

14. The patient support apparatus as set forth in claim 1 , wherein the barrier comprises a side rail operatively attached to the deck section for concurrent movement between the first section position and the second section position.
