The invention relates to a micro-organism reducing device, comprising a radiation device which is provided with a light source, a photosensitive substance which treats the area to be treated and is irradiated by said light source. The aim of said invention is to configure said device in such a way that it is possible to carry out an efficient and controllable treatment by means of operationally low-cost and easily handling apparatus. For this purpose, the inventive device comprises at least one applicator provided with a fiber-optic waveguide. In addition, said applicator and radiation device respectively comprise corresponding liaison bodies contacting one of them in such a way that the light from the light source is emitted towards the treated area by means of the fiber-optic waveguide.

1. An arrangement for reducing microorganisms, comprising: an irradiation device, which comprises a light source and a first connector body;a rotationally symmetric locking body having a first recess within which is positioned the light source, having a second recess within which is positioned a locking disk, and having a wall separating the light source and the locking disk, the wall having an opening through which light from the light source passes; andat least one applicator;wherein the locking disk is eccentrically positioned within the second recess by a wire spring to block light from exiting the opening;wherein the wire spring is mounted within a groove of the locking member in the second recess;wherein the locking disk has a conical surface with an opening at an apex of the conical surface;wherein the applicator comprises a light guide surrounded by a protective jacket and a second connector body, by means of which the applicator is detachably connected to the irradiation device via the first connector body thereof;wherein the first connector body and the second connector body correspond to each other and interlock with one another in such a way that the light of the light source can be irradiated through the light guide to a therapy site, onto which a light-activatable substance has been applied for therapeutic purposes;wherein upon insertion of said applicator the light guide is guided by the conical surface into the opening at the apex biasing the locking disk into an alignment of the wall opening and the locking disk opening;wherein for therapy of a region of the oral cavity, the light guide has a numerical aperture greater than 0.5 and one end free of the protective jacket, wherein the light beam emanating from the light guide diverges, the dimensions of the applicator are specified so that it can be introduced into the oral cavity without difficulty and configured as a pocket probe having a pointed conical tip or as a flat probe;wherein the irradiation device comprises a housing tube and a head part situated at the front end thereof, which is configured as the first connector body;wherein the light source and an electronic circuit board having an externally actuatable button are located in the front part of the housing tube; andwherein batteries or rechargeable batteries for supplying the electronic units for the light source with power are further provided in the housing tube, with a cap being detachably connected to the rear end of the housing tube via a threaded joint. 2. The arrangement according to claim 1, wherein the light source is a laser diode, and wherein light from the laser diode is coupled into the applicator either directly or via a lens package. 3. The arrangement according to claim 1, wherein the head part for receiving the applicator and light outcoupling is formed by a central borehole and/or that a front end of the head part engages with the second connector body. 4. An arrangement according to claim 1, wherein the central borehole is designed to receive and/or center the light guide end of the applicator. 5. An arrangement according to claim 1, wherein a key-operated switch is provided at the rear end of the housing tube or cap, whereby the irradiation device can be switched on or off. 6. An arrangement according to claim 1, wherein the applicators are designed as one-time optics for a single use. 7. An arrangement according to claim 1, wherein the housing tube comprises an operation display. 8. An arrangement according to claim 1, wherein a protective film is provided in the housing tube in the beam path in front of the light source. 9. An arrangement according to claim 1, wherein the second connector body is designed as a plug or screw fastener having a depth stop. 10. An arrangement according to claim 1, wherein the light guide of the applicator is guided through the second connector body, with a distal end of the light guide protruding from the second connector body by a predetermined length when a connection is established with the irradiation device, so that the applicator engages in the head part. 11. An arrangement according to claim 2, wherein the wavelength of the laser diode is 660 nm. 12. An arrangement for reducing microorganisms, comprising: an irradiation device, which comprises a light source and a first connector body;a rotationally symmetric locking body having a first recess within which is positioned the light source, having a second recess within which is positioned a locking disk, and having a wall separating the light source and the locking disk, the wall having an opening through which light from the light source passes; anda one-time optics applicator in sterile condition and packaged for single use;wherein the locking disk is eccentrically positioned within the second recess by a wire spring to block light from exiting the opening;wherein the wire spring is mounted within a groove of the locking member in the second recess;wherein the locking disk has a conical surface with an opening at an apex of the conical surface;wherein the applicator comprises a light guide surrounded by a protective jacket and a second connector body, by means of which the applicator is detachably connected to the irradiation device via the first connector body thereof;wherein the first connector body and the second connector body correspond to each other and interlock with one another in such a way that the light of the light source can be irradiated through the light guide to a therapy site, onto which a light-activatable substance has been applied for therapeutic purposes;wherein upon insertion of said applicator the light guide is guided by the conical surface into the opening at the apex biasing the locking disk into an alignment of the wall opening and the locking disk opening;wherein for therapy of a region of the oral cavity, the light guide has a numerical aperture greater than 0.5 and one end free of the protective jacket, wherein the light beam emanating from the light guide opens up significantly, the dimensions of the applicator are specified so that it can be introduced into the oral cavity without difficulty and configured as a pocket probe having a pointed conical tip or as a flat probe;wherein the irradiation device comprises a housing tube and a head part situated at the front end thereof, which is configured as the first connector body;wherein the light source and an electronic circuit board having an externally actuatable button are located in the front part of the housing tube; andwherein batteries or rechargeable batteries for supplying the electronic units for the light source with power are further provided in the housing tube, with a cap being detachably connected to the rear end of the housing tube via a threaded joint. 13. An arrangement according to claim 12, wherein the light guide is bent. 14. An arrangement according to claim 12, wherein the light guide is straight. 15.
