Bactericidal irradiator: characteristics. The bactericidal excipient OBN-150

In most medical institutions, ultraviolet irradiation is used to disinfect air, surfaces, water and medical instruments. It affects the environment and leads to the death of many harmful microorganisms.

What is an irradiator

The principle of operation of devices intended for air disinfection is the same. Each bactericidal irradiator produces ultraviolet, whose wavelength is about 253.7 nanometers. The power of such devices, as a rule, is not great. It is from 8 to 60 watts. In most cases, these are low-pressure mercury lamps .

The antibacterial ultraviolet irradiators consist of a housing that can be attached to a sheet or wall, a ballast, a power cable, a switch. Also included is a lamp itself. It looks like a tube-cylinder and is made of special glass. At its ends are soldered electrodes made of tungsten wire. The decontamination effect is achieved due to the radiation that arises from a glow discharge in mercury vapor under low pressure.

There are also xenon flash lamps. They also disinfect the room, while it is not contaminated with mercury vapor. Moreover, for disinfection with their help you need less time, because they create impulses of powerful radiation. But they have one big drawback, because of which only mercury lamps are used everywhere. For their work, high-voltage, expensive, complex equipment is needed.

Varieties

There are several types of irradiators. In medical, cosmetic centers, offices, stationary devices are often used. They can be attached to the shelves or the wall, on their body there are special grooves for fixing. Any such bactericidal irradiator is quite simple. The correct choice of the installation site allows to make the treatment of the premises as efficient as possible.

Mobile lamps are attached to a special rack. It can be equipped with wheels to facilitate movement. These options are well suited for large rooms. Lamps on racks that can be moved can be directed in one or different directions, be arranged in a circle or be narrow, and they can also be equipped with reflectors.

In addition, on sale it is possible to find irradiators-recirculators (they are also called irradiators of closed type). They are designed for long-term work in the premises where people and animals are. And here the bactericidal UV irradiator of open type can be included only there where there are no living beings. After its operation, the room should be ventilated.

In addition, there are ozone and ozone irradiators. In devices of the first type, a special material is used to fabricate a bulb of a lamp, which does not transmit waves whose length is less than 200 nm. Ozone lamps emit spectral lines shorter than 200 nm. In this case ozone is formed in the air.

Features of recirculators

For premises where there are a large number of people, including children, it is desirable to install irradiators of a closed type. Due to the fact that in their work there is no need to remove people and animals from the premises, they can work almost constantly. Such devices can be included in schools in classrooms, in kindergartens, in offices throughout the day. They work quite quietly, so they can be used even at night.

The principle of operation of recirculators is based on the fact that inside the housing there is a quartz lamp. The bactericidal irradiator is arranged in such a way that its body completely shields the ultraviolet irradiation. Decontamination of air is achieved due to the fact that it enters the device and exits it through specially ventilated apertures. The purification process itself passes directly into the irradiator.

Rules for the use of open lamps

In many medical institutions, not recirculators are installed, but open-type devices. With their help a fairly wide area around is disinfected. At the same time, not only air is cleaned, but all surfaces that are in the room are cleaned. But we must always remember that the bactericidal irradiator has a harmful effect on all living organisms. It can affect the skin, mucous membranes. Before turning on the quartz lamp, all living things must be removed from the room, including aquariums with fish and plants.

Given that in many medical institutions such lamps are installed directly in the wards, it is important to tell each incoming patient about the rules for their use. It is necessary to explain what can result in being in a room with the irradiator switched on. Carry out quartz in the premises should the junior medical staff.

How to choose

There are several basic nuances that you need to know about when you choose a germicide irradiator. The lamp should be of a certain power, which corresponds to the area of the room. The larger the area being treated, the stronger the apparatus should be.

Also important is the type of irradiator. The most optimal are the ceiling structures. But for wall variants, there are restrictions: they can not be placed on surfaces made of natural wood or wallpapered with wallpaper. These coatings under the influence of ultraviolet can blacken.

If you want to disinfect several rooms at the same time, the mobile irradiator will be the best option. Some manufacturers supply such lamps with a special platform, which is designed to facilitate the movement of the apparatus from room to room.

Particular attention should be given to documentation. You can only buy a medical device that has an instruction manual, all permits, including a certificate.

Illuminator OBN-150

Russian manufacturers are able to produce quartz lamps, the effectiveness of bactericidal action of which reaches 99.9%. A vivid example is the bactericidal OBN-150 irradiator.

This quartz lamp can be installed not only in medical institutions, including hospital hospitals, but also in bacteriological laboratories, in industrial plants, blood transfusion stations, in canteens, cinemas, gyms and other places of congestion.

With the help of OBN-150, air, household items, water intended for drinking can be disinfected. All this can prevent infection with bacteria and viruses. For a room with a volume of 150 m ³ , 35 minutes of lamp operation is necessary to completely disinfect it.

The supplied quartz lamps DB-30M are made of oily glass. It quietly transmits radiation at a level of 253.7 nm, but delays shorter wavelengths, the length of which does not reach 200 nm. This is able to prevent the formation of ozone in the air during the operation of the apparatus.

The operating life of the lamps, which are included in the bactericide OBN-150, is 8 thousand hours. The nominal power of the device is 60 W, it is capable of producing a bactericidal flow of about 22.4 W. At the same time, its service life is 5 years.

For those who plan a purchase, it is important to know that the weight of the device is 2.32 kg, its length is 942 mm, height - 162 mm, width - 54 mm. These settings will help you choose the most suitable place for installation.

The irradiator "Azov"

Now, more advanced quartz lamps have been developed, which can work both in the presence of people and carry out rapid disinfection in empty rooms. The irradiator bactericidal "Azov" is distinguished by its originality and simplicity of use. There are several models of this series. They vary in power, number of lamps and dimensions.

They are intended for disinfection of air and various surfaces in premises. There are two-lamp models, the electric circuit of which allows to include them separately. That is, while in a room people can work screened lamp, and in their absence - the usual. Distinctive features of the irradiators of the "Azov" series are the long service life of the lamps, high performance and reliability. With their help you can evenly disinfect the air in large rooms.

For example, the irradiator bactericidal wall "Azov" is equipped with two lamps of 30 W each. It emits waves of 253.7 nm in length. Its electrical circuit allows you to include only the upper shielded lamp. In this case, plants and people can remain in the room. At the same time, the power of the irradiator is 30 W.

It is established that the efficiency of such a quartz lamp is 0.65. At the same time, the efficiency of decontamination at an efficiency of 99.9% is 132 m ³ per hour.

The irradiators of the "Azov" series can use not only in medical and preventive institutions, such as polyclinics, hospital hospitals, maternity hospitals, dentists, cosmetology centers. They are also recommended for use in food shops, vegetable stores, canteens, and food units for the decontamination of containers and products. The use of lamps in children's educational and sports institutions can destroy 99.9% of microorganisms in the premises.

The main thing is to be careful when turning on and not to confuse the lamps, one of which can be switched on in the presence of people, and the other should only be used in empty rooms. After all, the use of an unshielded illuminating disinfection device can cause erythema and photophthalmia of the skin. For quick disinfection of the room, two lamps can be switched on simultaneously.

Methods of using quartz devices

There is a special technology for decontaminating the room. It is not necessary that the quartz irradiator bactericidal work without interruption. In rooms of all types, closed lamps, which can work in the presence of people, should function continuously for 1-2 hours. In the premises of medical institutions, such as procedural, dressing, laboratories, blood transfusion stations, operating rooms, open devices are used. They need to be turned on for 15-30 minutes. The break between irradiation sessions should be at least 1-2 hours.

Lamps for treatment: indications

But not all quartz lamps are equally harmful to living beings. There are, for example, devices designed for therapy with ultraviolet light. Thus, treatment with such irradiators can be shown for patients suffering from bronchial asthma, acute neuralgia, neuropathy of peripheral nerves, reactive and rheumatoid arthritis, deforming arthrosis, traumatic injuries of the musculoskeletal system and skin. They are also effective in the therapy of prolonged bronchitis, promote the healing of purulent wounds, decubitus, boils, inflammatory infiltrates. It is recommended to use them for treatment of shingles, erysipelas, which proceeds in acute or chronic form, various gynecological inflammatory diseases.

In addition, the bactericidal irradiator can be used for intracavitary irradiation. With its help, the conditions are eased in periodontitis, gingvinitis, periodontal disease, acute and chronic pharyngitis, tonsillitis, rhinitis. Irradiation promotes faster treatment of acute respiratory infections, inflammation in the middle and outer parts of the ears.

Contraindications

But there are a number of situations where the irradiator can not be used for treatment. Bactericidal lamp is contraindicated in the presence of any malignant neoplasms, regardless of the course of the disease, after radical operations, with systemic connective tissue diseases, exacerbations of peptic ulcer, chronic hepatitis, photodermatoses and increased sensitivity to UV rays.

Also, it is not recommended to use bactericidal irradiator in patients with active pulmonary tuberculosis, with propensities to bleeding, circulatory insufficiency, hyperthyroidism, arterial hypertension, acute cerebrovascular disorders, severe atherosclerosis, renal and hepatic insufficiency. In addition, the device is not used in febrile states, in the first 3 weeks after a previous myocardial infarction.

Sunshine irradiator

You can use quartz lamps both in medical institutions and at home. If you plan to use the device in a dwelling, you can buy UV irradiator "Sunshine".

He has a plastic case. On the front side, it closes with a special sliding screen. There are holes in it, into which the replaceable tubes are fixed.

In the kit with the irradiator there are protective glasses that are designed for children's size. Also included in the kit is the Gorbachev biodosimeter. With the help of this device it is possible to determine the individual bio-dose, which will be calculated taking into account all the physiological characteristics of the patient. This allows you to optimally choose the power of radiation, even for young children.

Before the procedure, it is necessary to install the necessary nozzle-tube, turn on the device and wait about 5 minutes. After stabilizing the lamp, you can start the treatment. If local therapy is necessary, then it is necessary to remove the damper. With the help of a lamp, it is possible to irradiate limited areas of skin whose area does not exceed 600 cm ² .

By the way, the bactericidal irradiator "Solnyshko" can be used for disinfection of premises. To do this, simply remove the protective screen and turn on the device for about 30 minutes. Before such a procedure, do not forget to remove from the premises of the plant, to withdraw people and animals.

Usage feedback

The effectiveness of quartz lamps for indoor spaces has been proven by many studies. It is confirmed that irradiators are the cause of destructive photochemical modifying lesions in the DNA structure of microorganisms. The most sensitive are cocci and rods - bacteria of the vegetative form. Protozoa and fungi are not as sensitive to radiation as the bactericidal irradiator produces. Feedback from experts and researchers suggests that spore forms of bacteria are the least susceptible.

If we talk about medical devices, it becomes interesting to the opinion of patients who used them. So, many say that with their help you can completely get rid of rhinitis, manifestations of skin diseases, ease the condition in ARI. All these problems help to solve the bactericidal irradiator "Solnyshko". True, he also has shortcomings. These include, in particular, the curtain, which has no attachment, and not too comfortable glasses. Also, some patients say that it is not entirely clear how to change the lamp if it burns out.
