Display apparatus for an operating room

1. A display apparatus, having:

an image surface to display medical information in a medical treatment facility,

such that the image surface is configured to convert by reshaping from an operating condition into a resting condition and vice versa, and

the image surface has a substantially positive Gaussian curvature in the operating condition, the image surface comprising a plurality of areas that in the operating condition each have a concave shape

wherein the image surface is mounted to a ceiling.

2. The display apparatus according to claim 1 , wherein the image surface is a projection surface.

3. The display apparatus according to claim 2 , in addition having:

a projection system to project a depiction of information onto the projection surface, wherein the projection system includes a light source, a light modulator and an imaging device such that the light source is set apart from at least one of the imaging device or the light modulator.

4. The display apparatus according to claim 1 , wherein the image surface is constituted by a light-emitting image screen.

5. The display apparatus according to claim 1 , wherein in the operating condition the areas form the image surface and in the resting condition the areas are disposed at a distance from one another.

6. The display apparatus according to claim 1 , in addition having a rectification device to reshape an image that is to be depicted by the image surface in such a way that the image is perceived by an observer at a predetermined location as non-distorted.

7. The display apparatus according to claim 1 , in addition having:

a rectification device with an input for receiving a signal that depends on a position of an observer, such that the rectification device is configured in order to control the display apparatus depending on the position of the observer.

8. The display apparatus according to claim 1 , in addition having:

a container that is configured to receive the image surface in a resting position.

9. A display apparatus for displaying medical information in a medical treatment facility, having:

an image surface to display information, such that the image surface is configured to convert by reshaping from an operating condition into a resting condition and vice versa, and the image surface has a substantially positive Gaussian curvature in the operating condition, the image surface comprising a plurality of areas that in the operating condition each have a concave shape, and

a container that is configured to receive the image surface in a resting position,

wherein the container is attached in a movable manner to a track on a ceiling surface of a medical treatment facility.

10. The display apparatus according to claim 9 , in addition having:

a power drive device to move the image surface between the resting position inside the container and an operating position in which information can be depicted visibly for medical staff on the image surface.

11. A display apparatus for displaying medical information in a medical treatment facility, having:

an image surface to display information, such that the image surface is configured to convert by reshaping from an operating condition into a resting condition and vice versa, and the image surface has a substantially positive Gaussian curvature in the operating condition, the image surface comprising a plurality of areas that in the operating condition each have a concave shape,

wherein the image surface is a projection surface that can slide along a path determined by a track device and wherein the display apparatus in addition includes a projector that can slide along the path to project a depiction of information onto the projection surface and a positioning device to establish the positions of the projector and projection surface on the path, such that the positioning device is configured to position the projector and the projection surface at positions essentially opposite one another on the path determined by the track device.

12. A display apparatus for displaying medical information in a medical treatment facility, having:

an image surface to display information, such that the image surface is configured to convert by reshaping from an operating condition into a resting condition and vice versa, and the image surface has a substantially positive Gaussian curvature in the operating condition, the image surface comprising a plurality of areas that in the operating condition each have a concave shape,

the image surface being a projection surface, and

a projection system to project a depiction of information onto the projection surface, wherein the projection system includes a light source, a light modulator and an imaging device such that the light source is set apart from at least one of the imaging device or the light modulator,

wherein the light source is mounted above a ceiling surface of the medical treatment facility, and at least one of the imaging device or the light modulator is mounted below the ceiling surface.

13. A display apparatus for displaying medical information in a medical treatment facility, having:

an image surface to display information, such that the image surface is configured to convert by reshaping from an operating condition into a resting condition and vice versa, and the image surface has a substantially positive Gaussian curvature in the operating condition, the image surface comprising a plurality of areas that in the operating condition each have a concave shape, and

a foldable structural device and an elastic membrane that is held by the foldable structural device and forms the image surface.

14. The display apparatus according to claim 13 , wherein the elastic membrane can be removed from the foldable structure and can be sterilized separately.
