Abstract
A device for detecting the position of movable operating table components that has a multilayer sensor film that is attached to a first operating table component; a slider that is mounted on a second operating table component which is movable relative to the first operating table component, the slider being equipped with a pressure piece that elastically compresses the multilayer sensor film; and -n electrical circuit, which generates a signal in accordance with the position of the pressure piece on the sensor film.
Claims15
A device for detecting the position of movable operating table components, the device comprising:
- a multilayer sensor film attached to a first operating table component;
- a slider attached to a second operating table component, the slider is movable relative to the first operating table component and is equipped with a pressure piece that elastically compresses the multilayer sensor film;
- and
- an electrical circuit comprising a potentiometer circuit, which generates a signal in accordance with the position of the pressure piece on the sensor film,
- wherein the multilayer film sensor comprises an upper layer, a lower layer, and an elastically compressible intermediate layer arranged between the upper and the lower layers,
- wherein the upper and lower layers of the multilayer film sensor each have electrically conductive coatings, and
- wherein electrical contact between the upper and lower layers of the multilayer film sensor is achieved by compression of the intermediate layer at the position at which the pressure piece is in contact with the multilayer sensor film.
An operating table, comprising:
- a bearing surface having a first component and at least one second component that is movable relative to the first component,
- at least one hydraulic adjusting element for moving the second component relative to the first component, and
- at least one multilayer film sensor for detecting a position based on a potentiometer circuit, wherein the multilayer film sensor is attached to the hydraulic adjusting element and is configured to determine the position of the second component relative to the first component,
- wherein the multilayer film sensor comprises an upper layer, a lower layer, and an elastically compressible intermediate layer arranged between the upper and the lower layers,
- wherein the upper and lower layers of the multilayer film sensor each have electrically conductive coatings, and
- wherein electrical contact between the upper and lower layers of the multilayer film sensor is achieved by compression of the intermediate layer.
A method of operating an operating table, the method comprising the steps of:
- receiving within a control unit of the operating table one or more electrical measurements associated with an output of a multilayer film sensor;
- and
- controlling with the control unit a movement of the operating table based on the step of receiving within the control unit of the operating table the one or more electrical measurements,
- wherein the multilayer film sensor comprises a potentiometer circuit and includes an upper layer, a lower layer, and an elastically compressible intermediate layer arranged between the upper and the lower layers,
- wherein the upper and lower layers of the multilayer film sensor each have electrically conductive coatings, and
- wherein electrical contact between the upper and lower layers of the multilayer film sensor is achieved by compression of the intermediate layer.
