CONCEPTUAL SOLUTION OF THE SYSTEM FOR DISINFECTION OF DOOR HANDLES, HANDLES ON STAIRS AND PUBLIC TRANSPORT AND FOOD COUNTERS AND PAYMENTS
1. INTRODUCTION
The subject of this application is a product that is mounted on door handles, handrails on stairs and public transport, ie in front of and behind counters for selling food and making payments in order to disinfect and prevent the spread of viruses and bacilli that are retained and thus transmitted from person to person. (transmission). In connection with current events, during the COVID-19 pandemic, it is very important to maintain the normal life of citizens, but it is even more important to prevent the transmission of the virus and the spread of the infection among the population. Research conducted by various health organizations, including the World Health Organization (WHO), clearly shows that places and objects that are burdened with a large fraction of people are the most at risk for transmitting the infection.
2. PRINCIPLE OF WORK
This system consists of several parts: -cover - bottle with disinfectant -fastening mechanism It is a sponge cover that is mounted on handles, handrails and barriers in the form of "roll bars", which are mounted in front of and behind the places where food is sold and paid for. For handles and shorter surfaces to be protected, this product is similar to plastic, silicone covers that are mounted on the ends of the handlebars of bicycles and motorcycles. At the bottom, at the beginning, there is a fastening system, and on the upper side, at the beginning, there is a conical hole with a thread (nut) for fastening a plastic bottle with disinfectant. This is a standard JUS thread for plastic bottles, 3mm increments. For handrails, roll bars and longer surfaces that we protect, the principle of operation is the same, only the fastening system is located every 500 mm and there are several conical threaded holes (nuts) for fastening plastic bottles with disinfectant. The sponge cover is actually a reservoir for disinfectant liquid, on the inside of the pipe there is a waterproof layer, which serves to prevent damage to the material from which the handles or handles are made. only a small layer of liquid and on that occasion disinfects the hands.
3. PRACTICAL APPLICATION
The sponge cover serves as a reservoir in which the disinfectant liquid is located and when the door is opened or closed, while passengers adhere to the handrails in public transport (bus, tram, trolleybus, train, metro ...) their hands are in contact with the disinfectant. means and practically ends the transmission of the virus at that point. In the case of "roll bars", which are located in front of and behind the counters for food sales and payment, the principle is that the user of the service (payment of bills, withdrawal of documents, payment for food, ...) saves money in his hands , so he gives the money to the service provider. The service provider (clerk in public institutions, nurse in the hospital, food seller at the cash register in the bakery, large or small discount stores or shops) grabs the "roll bar" with his hands, takes money or a document from the service user (party) and thus disinfects it. In the case of transfer from the service provider to the service user, the principle is the opposite, the service provider takes a document, food or change intended for the service user, grabs the "roll bar" and thus disinfects the hands, then hands it to the service user.
4. NOTES FOR USE
When choosing a system, you should take into account the number of people who will use this system. That is, what is the projected and actual frequency of users. Based on that, the size of the disinfection bottle is selected, ie its volume. This protection system is such that there is no need for protective gloves and we all need to use it to make the effect as good as possible.
