The device in question consists of a fixed Instead of using a stand or stable surface, it constantly engages itself during work. A moving metal conveyor system that disinfects is used. The subject of the invention is... Thanks to this device, the disinfection process does not require any chemical disinfectants or ozone. dry surface based solely on ultraviolet-C (UV-C) radiation without the use of other methods 10 This is carried out through disinfection. State of the Art Today, hygiene in public spaces that are heavily used by people is crucial. ensuring sustainable access to infectious diseases reduces their spread. 15 It has become an important requirement, especially for a large number of people in a short time. Commonly used surfaces that come into contact with each other at intervals can transmit microorganisms from one user to another. It can facilitate the transfer of goods from one place to another. Shopping malls, hospitals, security checkpoints located in courthouses, public institutions and similar areas Surfaces where personal belongings are temporarily left are also such common contact surfaces. 20 It is among them, and depending on the intensity of use, it is regular and effective. This creates a need for disinfection. Mobile phones pose numerous potential risks due to being frequently touched surfaces. They are considered important reservoirs that can harbor pathogenic microorganisms. 25 Inanimate objects can harbor microorganisms found in the environment, and They can carry pathogens. Inanimate surfaces in public spaces play a mediating role in the spread of pathogens. It is stated that microorganisms can play a role. Microorganisms can be found on doorknobs, elevator buttons, and It has been determined that it can be transmitted through similar common contact surfaces. This Microorganisms can then transfer to another surface, including the human body, within 30 days. can be transmitted. Also, some intestinal and respiratory pathogens can be found on inanimate surfaces. The fact that these surfaces can remain alive for hours to months makes them a public health risk. Its importance is increasing. Scientific studies have shown that the most common type of isolation in mobile phones... Among the bacteria identified, Staphylococcus aureus and Staphylococcus aureus were particularly prominent. 2 Staphylococcus species such as epidermidis are prominent, and these bacteria cause skin infections. It has been noted that it can lead to various infections, including sepsis. In addition... Escherichia coli and Klebsiella pneumoniae showing fecal contamination. Enteric bacteria, such as those mentioned, are frequently detected on mobile phones and can cause gastrointestinal problems. It can cause urinary tract infections. Also, Pseudomonas aeruginosa 5 Opportunistic pathogens such as these can lead to serious infections, especially in immunocompromised individuals. While open, Enterococcus spp. species are hospital-acquired infections and antibiotics It is associated with resistance. In the literature, a large proportion of mobile phones have this. because it is contaminated with bacteria and poses a significant risk of cross-contamination. It is emphasized that in the electromagnetic spectrum, ultraviolet (UV) radiation is visible. 10 It lies between light and X-rays. UV radiation, depending on its wavelength, is divided into UV-C (200– They are classified as UV-B (280 nm), UV-B (280–315 nm) and UV-A (315–400 nm). UV-C radiation with a wavelength of 253.7 nm is the ultraviolet radiation of the natural solar spectrum. It is located in this section and contains a wide range of microorganisms, including bacteria, viruses, yeasts, and molds. It exhibits significant disinfectant properties against the spectrum. The germicidal effect of UV-C is 15 photochemical reactions such as photohydration, photothermal, and photodissociation, It is primarily mediated through photodimerization and photophysical effects; all of which It contributes to cellular damage and inhibition of proliferation processes. Microbial The inactivation mechanism involves the destruction of nucleic acids by UV-C radiation. In current practices, shopping malls, courthouses, police units, governor's offices, At hospitals and similar security checkpoints, visitors are asked to hand over their cell phones, wallets, The surfaces where people temporarily leave their keys and similar personal belongings are usually fixed. They are designed in the form of a side table, desk, or platform. These surfaces are used extensively throughout the day. Despite being used jointly by a large number of users, hygiene continuity is maintained at 25 It does not have an integrated and automated disinfection mechanism to provide this. In known applications of this technique, cleaning these surfaces largely depends on a specific time period. This depends on manual cleaning and disinfection procedures carried out at intervals. Manual applications, on the other hand, include cleaning frequency, staff practices, workload, and usage. Since it depends on variables such as density, surface hygiene should be maintained for each use 30 days. It cannot guarantee that it will be maintained at the same standard afterwards, especially in densely populated areas. At security checkpoints with high traffic, the same contact surface is used within a short period of time. Its use by numerous different users ensures the continuity of surface hygiene. This makes it difficult to achieve. The current state of the art involves UV-C based technology. 3 When the systems are examined, the solutions largely involve bags, suitcases, grocery products, packages, different targets such as air, liquid, escalator handrail or moving walkway It appears that the purpose is disinfection. Common features of these systems include... a system that enables the contact surface to automatically disinfect itself It is not foreseen. 5 In addition, a significant portion of existing systems use chemicals in addition to UV-C radiation. disinfectants, fogging systems, ozone or similar auxiliary disinfectants These methods are utilized. This increases system complexity, and additional This creates a need for maintenance and in some applications chemical residue or ozone 10 This may require additional security measures. In addition... Current solutions involve leaving personal belongings at security checkpoints. a movable carrying surface that can replace the stands in each usage cycle It does not offer a compact and integrated system that automatically disinfects. Fixed Hygiene problems related to surfaces and user density persist, hygiene 15 The process and the usage process are carried out independently of each other.

These systems are mostly used to directly expose objects, products, etc. to UV-C radiation. It aims to disinfect air or fluids, and personal belongings. a system for automatically disinfecting shared contact surfaces where food is left. It does not offer a solution. Existing solutions generally involve directly interacting with objects and... For the disinfection of items such as bags, suitcases, and grocery products, or of liquids. 4 However, it is observed that users at security checkpoints... the shared contact surfaces where they temporarily leave their personal belongings targeting itself and a system that dynamically disinfects this contact surface in isolation from the user. The system is not included in the known state of the art. It is not included in the known state of the art. The field documents cover different applications of UV-C disinfection technology. 5 Personal item placement surfaces are automatically disinfected with UV-C. a system based on a moving metal conveyor and controlled by PLC for this purpose. It does not define it. It is a common place where personal belongings are left during security checks. the contact surface is UV-C in a closed system that does not come into contact with the user. Automatic disinfection of the moving metal conveyor surface 10 Based on this principle, its PLC-controlled parametric structure is designed to target pathogens. Enables dynamic UV-C dose optimization and microbiological validation studies. A system that recognizes it is not included in the known state of the art.
