Abstract

Claim for protection A changing room with UV disinfection regimes for people, in which the cabin has a coat rack, clothes hooks and one or more doors, characterized in that there are UV lamps of the wavelengths between 200-300nm on the inside and the ceiling of the cabin. that the emitters are arranged in such a way that all open surfaces in the interior are irradiated with UV light and there is an indicator on the outside or next to each door about the condition of the interior cabin, inside there are one or more sensors that detect whether there are people and / or clothes are in the cabin and there is an electronic system that collects the data from the sensors, takes over the control and lighting display and locks the doors.

Description

Changing rooms, for example in clinics, medical practices, but also special treatment facilities such as cold rooms, therapy centers, etc., are used for patients in a small closed cabin with one, possibly two doors, a bench, a coat hook, a mirror and the like exist. These changing rooms are a relatively risky transmission point for germs, bacteria, viruses and the like. These have to be cleaned with disinfectant several times a day, if possible after every change of person.

• Es wurden Patentrecherchen mit der online-Datenbank DPMA durchgeführt. Bei diesen Recherchen wurden einige trefferrelevante Patentanmeldung bzw. Gebrauchsmusteranmeldungen gefunden:
  • Es besteht die Patentschrift DE 10 2016 013 087 A1 , welche eine Türklinke beschriebt, die den Griff durch eine bewegte Einheit desinfiziert. Dabei erfolgt die Desinfektion durch UV-Licht und wird über die Griffanordnung bewegt. Diese Anordnung hat den Nachteil, dass der Griff stationär ist und eine aufwendige Umrüstung der Türgriffe erfolgen muss und somit das Design und die Form des Türgriffes vorgegeben ist. Solch eine Vorrichtung könnte insbesondere in medizinischen Einrichtungen Anwendung finden, aber nicht für den breiten Gebrauch.

Weiterhin ist die Patentschrift DE 699 12 849 T2 bekannt, welche ein tragbares Gerät zur Desinfektion von kleinen Gegenständen über eine Blitzlampe beschreibt. Diese Anordnung ist für kleine Gegenstände, die im Innenraum arretiert werden anwendbar. So ist bspw. auch eine Desinfektionsvorrichtung für Innenräume bspw. für Geschirrspüler bekannt ( DE 20 2012 102 250 U1 ). Des Weiteren sind Patentschriften bekannt, welche sich mit der Desinfektion von Oberflächen und Raumluft befassen ( DE 20 2017 100 914 U1 ). Die Patentschrift DE 20 2018 103 840.0 beschreibt die Desinfektion von textilen Gegenständen, bspw. Kleidung. Die Patentschrift DE 20 2019 002 973 beschäftigt sich mit der UV-Desinfektion für Küchen, insbesondere eine besondere geometrische Anordnung zur Desinfektion von Küchenschwämmen mit UV-Strahlung.Another version is the irradiation with UV light. So far there are a number of solutions:

• Patent searches were carried out with the online database DPMA. In the course of this research, a number of patent applications and utility model applications relevant to the hit were found:
  • There is the patent specification DE 10 2016 013 087 A1 , which describes a door handle that disinfects the handle by a moving unit. Disinfection is carried out using UV light and is moved using the handle arrangement. This arrangement has the disadvantage that the handle is stationary and the door handles have to be converted in a complex manner and the design and shape of the door handle is therefore predetermined. Such a device could be used in particular in medical facilities, but not for widespread use.

Furthermore, the patent DE 699 12 849 T2 known, which describes a portable device for disinfecting small objects using a flash lamp. This arrangement is applicable for small items that are locked in the interior. For example, a disinfection device for interiors, for example for dishwashers, is also known ( DE 20 2012 102 250 U1 ). Furthermore, patents are known which deal with the disinfection of surfaces and indoor air ( DE 20 2017 100 914 U1 ). The patent DE 20 2018 103 840.0 describes the disinfection of textile objects, e.g. clothing. The patent DE 20 2019 002 973 deals with UV disinfection for kitchens, in particular a special geometric arrangement for disinfecting kitchen sponges with UV radiation.

It is still the utility model DE 20 2019 003 728 U1 known, which describes a mobile mold removal device, which works on the basis of UV radiation.
These property rights do not relate to the UV LED range between 250 and 300nm or are not suitable for mass use.

However, these solutions are unable to efficiently disinfect the changing rooms mentioned above.

A solution should therefore be found to disinfect small, compact changing rooms within a few 10 seconds without great effort, in particular the surfaces in the changing room, such as shelves, clothes hooks, wall mirrors, handles and switches. The main focus is that disinfection is completely harmless for the person concerned.

According to the invention, an arrangement is therefore constructed in which all the surfaces which can come into contact with a person and which can come into contact with UV light are irradiated in the changing room. These can be plasma UV tubes, for example, which irradiate all surfaces from the walls but also from the ceiling. It is also possible to use LED spotlights in the range of 200 - 300nm.
So that all surfaces are irradiated in a relatively short time and thus the germs, bacteria, fungi and viruses are destroyed, shelves for changing are usually set up as closed areas which, for example, have a closed level at the top. The clothes hooks and door handles are designed similarly so that they are completely hit by the UV radiation. This makes it possible to use the UV lamps on the walls and in the ceiling to irradiate all surfaces that the person normally comes into contact with. Usually materials are used that are resistant in a UV range between 200 and 300nm. This applies in particular to the materials and surfaces for the coat racks, but also the clothes hooks for the door handles, door and wall surfaces.
The UV radiation in the range 200-300 nm takes place over a predetermined time t with the corresponding intensity i. These are set in such a way that the germs, bacteria, fungi and viruses on the surface are optimally destroyed.
Corresponding germs, bacteria, fungi and viruses in the air can also be destroyed with the help of UV radiation in the range from 200 to 300 nm, which are found in the air, for example due to the exhalation of mini droplets by people. The dose or time is set using a switch, controller or electronics. It is possible that this time regime or time intensity regime can be adapted within a certain period of time based on new scientific knowledge or the like.

Of particular importance for the UV changing room is the fact that it must be ensured that when radiation is taking place, the door or doors are securely closed and there is no one in the room. For this reason, a sensor system is usually installed indoors, which reliably signals that a person is in the room. This sensor system can be, for example, a motion detector, an infrared camera or a normal camera. It is common for the presence of a person in the room to be detected by several types of sensors and thus to rule out the possibility of the UV light coming on when there is still a person in the room.

• - Anschalten des UV-Lichtes,
• - UV-Licht aus; keine Person drin; Kabine desinfiziert,
• - Personen in der Kabine,
• - Personen sind nicht in der Kabine, aber Gegenstände der Person sind innerhalb der Kabine, sodass diese zurückkehrt.

In addition, it is common to attach a signal next to the outer door or outer doors, which signals the following states:

• - switching on the UV light,
• - UV light off; no person in it; Disinfected cabin,
• - people in the cabin,
• - People are not in the cabin, but objects of the person are inside the cabin so that it returns.

• - „Kabine ist leer; die Desinfektion wird über das angeschaltete Blaulicht durchgeführt.“ Dies wird an den Displays außen angezeigt.
• - Nach dem Zeitpunkt X wird die UV-Strahlung ausgeschalten. Es erfolgt eine entsprechende Anzeige.
• - Signalisierung, dass die Kabine frei ist.
• - Person geht in die Kabine und hält sich dort auf. Signalisierung am Außenbereich.
• - „Person verlässt Kabine; Sachen befinden sich in der Kabine“ wird außen signalisiert.
• - „Person ist in der Kabine“ Signalisierung außen.
• - „Person verlässt Kabine; keine Sachen befinden sich in der Kabine.“ Anzeige außen.
• - „Automatisches Verschießen der Türen; Anschalten der UV-Strahlung“ Signalisierung - anschließend Freigabe der Kabine für nächste Person

These displays are created on the basis of the sensor system, which means that the sensor system detects whether a person is inside the cabin (motion detector, NIR-IR camera, normal camera) and the corresponding display elements that are located on the outside of the display. The following mechanism can be implemented using this electronics, the sensors and the display elements:

• - "Cabin is empty; disinfection is carried out using the switched on blue light. ”This is shown on the outside of the displays.
• - After time X, the UV radiation is switched off. A corresponding display is shown.
• - Signaling that the cabin is free.
• - Person goes into the cabin and stays there. Outdoor signaling.
• - "Person leaves cabin; Things are in the cabin ”is signaled on the outside.
• - "Person is in the cabin" signaling outside.
• - "Person leaves cabin; there are no things in the cabin. ”Outside display.
• - "Automatic closing of the doors; Switch on the UV radiation "signaling - then release the cabin for the next person
