Abstract

Claims (34)

1 . A system for disinfection of surfaces, comprising:

a medical component associated with one or more of (i) a medical device, (ii) an item of equipment of a medical examination, or (iii) a treatment room for a medical examination; and

an ultraviolet (UV) light source coupled to and integrated as part of the medical component, the UV light source being configured to perform disinfection irradiation of at least one surface to perform a medical examination and/or treatment;

a controller configured to selectively operate the system in an examination mode and a disinfection mode,

wherein the medical component is configured to be moved mechanically in (i) the examination mode for the purpose of the medical examination and/or the treatment, and (ii) the disinfection mode distinct from the examination mode for the purpose of performing a disinfection cycle,

wherein the controller is configured, in response to a triggering condition being satisfied, to switch the system from operating in the examination mode to operating in the disinfection mode and perform the disinfection cycle, and

wherein the UV light source is configured, during the disinfection mode, to generate UV light and to be moved via movement of the medical component in accordance with a predetermined movement pattern, which differs from movement of the medical component during the examination mode, to thereby perform the disinfection irradiation.

2 . The system as claimed in claim 1 , wherein the medical component comprises a movably-arranged x-ray source, and

wherein the UV light source is arranged on the movably-arranged x-ray source.

3 . The system as claimed in claim 1 , wherein the medical component comprises a movably arranged x-ray detector, and

wherein the UV light source is arranged on the movably arranged x-ray detector.

4 . The system as claimed in claim 1 , wherein the medical component comprises an x-ray device or a C-arm system, and

wherein the UV light source is arranged on a cladding of the x-ray device or the C-arm system.

5 . The system as claimed in claim 1 , wherein the UV light source is arranged on one of a wall mount, a floor mount, a ceiling mount, a swivel arm, or a cable.

6 . The system as claimed in claim 1 , wherein the UV light source is configured to be placed at, on, or above an operating device.

7 . The system as claimed in claim 6 , wherein the operating device comprises a UV-transparent component.

8 . The system as claimed in one claim 1 , wherein the UV light source is arranged on the medical component such that at least a portion of a further medical device is irradiated when the medical component is laid on or passed through the medical device.

9 . The system as claimed in claim 8 , wherein the medical component comprises a sensor configured to detect a presence of the further medical device and/or contaminations.

10 . The system as claimed in claim 1 , further comprising:

a UV light-reflecting element configured to reflect and direct the UV light generated via the UV light source to other areas in addition to areas directly exposed to the generated UV light.

11 . The system as claimed in claim 1 , further comprising:

a sensor configured to detect one of (i) a radiation dose, (ii) a presence of humans and/or devices, (iii) a position of humans and/or devices, and (iv) a macroscopic surface contamination.

12 . The system as claimed in claim 1 , wherein the UV light source is from among a plurality of UV light sources, the UV light source being arranged in and/or on an examination area of a medical imaging device, and further comprising:

a means for creating an air flow configured to move air into an area to be irradiated with the UV light via the plurality of UV light sources; and

an examination area ventilation system comprising an air channel identified with the air flow in which the plurality of UV light sources are arranged to irradiate air flowing through the air channel.

13 . The system as claimed in claim 1 , wherein the triggering condition comprises a determination, via a sensor, that a person is no longer in a region in which the disinfection irradiation is to be performed.

14 . The system as claimed in claim 1 , wherein the UV light source is configured, during movement in accordance with the predetermined movement pattern, to vary a UV radiation intensity of the disinfection irradiation.

15 . The system as claimed in claim 14 , wherein the UV light source is configured to vary the UV radiation intensity of the disinfection irradiation based upon a type of medical examination previously performed via the medical component.

16 . A method for disinfection of surfaces

with an ultraviolet (UV) light source

that is coupled to and integrated as part of a medical component, the method comprising:

selectively controlling, via a controller, the medical component to be moved mechanically in (i) an examination mode for the purpose of a medical examination and/or a treatment, and (ii) a disinfection mode distinct from the examination mode for the purpose of performing a disinfection cycle;

in response to a triggering condition being satisfied, switching, via the controller, from the examination mode to the disinfection mode; and

performing, during the disinfection mode, the disinfection cycle by moving the UV light source via movement of the medical component in accordance with a predetermined movement pattern, which differs from movement of the medical component during the examination mode, to thereby perform the disinfection irradiation.
