Isolator: what is it and why is it needed?

An isolation ward is a separate room designed for the temporary isolation of people who are sick with infectious diseases or are suspected of having them. Isolators are created at hospitals, clinics, sanatoriums, kindergartens, boarding schools, dormitories, first-aid posts at train stations, ports and other places where there is a risk of the spread of infections.

Isolators perform an important function - they help prevent the spread of infections among the population. When a person is suspected of having an infectious disease, he is placed in an isolation ward, where he receives medical care and takes the necessary measures to prevent the spread of the disease.

For some infectious diseases, such as influenza, whooping cough, measles and others, the patient can be isolated at home. In this case, a separate room or a corner of the room fenced off with a screen can serve as an insulator. In this case, the patient is allocated separate dishes, linen and personal care items, and the room, dishes and other household items are regularly disinfected. Carers must strictly follow certain rules and doctor's advice.

However, for more serious infectious diseases, such as plague, smallpox and other especially dangerous diseases, the isolation ward is not a temporary, but a permanent place of stay for patients. Such isolators are equipped in accordance with the instructions and the anti-epidemic regime is strictly observed. Services for patients in the isolation ward are carried out in compliance with strict rules of hygiene and disinfection.

In isolation wards, patients are given separate dishes, linen and personal care items, and the premises, dishes, linen, household items, etc. are systematically disinfected. People who are in contact with someone who is sick may also need to be vaccinated to prevent the spread of infection.

Thus, isolation facilities play an important role in the fight against infectious diseases by preventing their spread among the population. They are created in various places where there is a risk of infection, and are supplied with all the necessary equipment and medications to combat infection. It is important to remember that good hygiene and preventive measures are key factors in controlling the spread of infections.

Title of the material: "Insulators: history and application in the modern world"

An insulator (French Isolateur) is a device or material for electrical insulation. Insulators are used in electrical engineering to separate live parts of electrical equipment that are energized.

History of Isolators

The first insulators appeared in the 19th century, when the need arose to modernize arc lamps. They were made of porcelain and functioned like a candle, allowing gas to be maintained within the lamp. Despite this, they did not improve the light production of the lamp or increase its life, which limited their use. Over the next two centuries, inventors searched for ways to create better insulators. Several attempts were made to develop completely sealed lamps (such as Edison's lamp), but these also failed. With the development of modern electrical power, new types of insulators have been developed, including composite materials and materials with different characteristics, such as mechanical strength, electrical strength and thermal expansion. This has improved the quality and efficiency of insulating materials and devices.

Modern insulators are used in various fields, including energy, mechanical engineering and electronics. Their main purpose is to prevent short circuits between current-carrying elements, and they must meet safety and reliability requirements. Depending on the voltage level for which the insulator is manufactured, it may have different characteristics and designs. For example, porcelain insulators are divided into several types, which are used for installation of electrical networks for voltages of 6-20 kV and higher. There are also various types of ceramic, glass epoxy, and basalt fiber insulation used to improve the efficiency of electrical systems. Other types of insulating materials, such as paper insulators, plastic bushings and moldings, can be used to insulate cables and wires. The use of insulators in the modern world

Let us dwell in more detail on the use of insulators in our contemporaries. Technological progress has led to the emergence of a wide range of cable and overhead lines of high voltage that transmit electrical energy to the consumer - the city, the enterprise. When these lines were laid, it was necessary to work with high and ultra-high voltage, which currently no longer needs to be grounded, the wires must be insulated from each other, and they must be attached to a support or pole. To solve these problems, various types of insulators are needed (knitting needles, caps, plugs and other types).

In addition, insulators play an important role in high-voltage power plants. They are installed along power lines to protect the town or village through which the wires pass from the danger of floods or fires. Insulation ensures safety for others and prevents damage to equipment.
