The air surrounding us contains microorganisms, the diversity of which is quite large. Along with bacteria useful for the body, there is also a pathogenic microflora that can cause pathological conditions.
In order to prevent the spread of infection in medical institutions, special devices are widely used - lamps for disinfecting rooms that can disinfect the air. You can apply them at home.
Types of lamps
- Standard UV is a gas filled bulb with electrodes. The electric arc that occurs when voltage is applied promotes the evaporation of mercury, which in the form of gas is a source of energy. High permeability of the device is ensured by quartz, which is used for the production of lamps. The service life and reliability of the product directly depends on the materials from which the electrodes are made. The molybdenum foil with platinum elements located at its ends helps to operate the device at high temperatures.
- Bactericidal is a gas-discharge mercury electric lamp, the bulb of which is made of a special material that can provide the necessary transmission spectrum of UV radiation for the purpose of disinfection. The difference between this device and a quartz lamp is that it retains hard ultraviolet light. After quartzizing using a bactericidal device, ventilation is not required. Bactericidal lamps for disinfection of the room are mainly used to neutralize pathogens: viruses, fungi of various nature, bacteria. When working with this type of medical device, one should not forget about the negative influence of ultraviolet rays on the organs of vision and skin.
- Quartz is a mercury electric gas discharge device that has a quartz glass flask . Its purpose is to obtain ultraviolet radiation.
- Mercury-quartz is a gas-discharge lamp in which mercury is added. The flask is made of special uviole glass. Main use: disinfection of food, premises, various items. It is used in medical organizations.
UV lamps: classification
The advantages of these medical disinfection lamps are affordable price and high efficiency. Their types are as follows:
- Open . Devices of this type destroy pathogenic bacteria both on surfaces and in the air. Disadvantages: negatively affect living organisms. During their work, people and animals should not be in the room. Lying patients are covered with a blanket during the procedure.
- Closed . This indoor disinfection lamp can be used in the presence of people. Principle of action: dirty air enters the chamber for disinfection and then disinfected.
- Special They are used for manipulations in the treatment of pathological conditions in otolaryngology, pulmonology, dentistry.
The first two types of quartz lamps for disinfection of a room are used in medical organizations, school and preschool institutions. Specials are widely used in medical institutions for the provision of outpatient and inpatient care, as well as at home.
Ultra-violet rays
Ultraviolet light reaching the Earth’s surface is classified as:
- A - these are safe for the body rays with a wavelength of 320 to 400 nm, which make up about 98% of the total.
- B - favorably affect the human dermis in small quantities, contribute to the production of vitamin D. The wavelength varies in the range of 280-320 nm.
- C - destroy the DNA of microorganisms and are dangerous to humans. The wavelength is from 100 to 280 nm. The ultraviolet rays of this group reach the Earth a small amount.
Since the last century, medical organizations have been using lamps to disinfect rooms with an optimal wavelength of 253 nm, which destructively affects pathogenic microorganisms, resulting in the death of the latter.
Contraindications to the use of UV lamps
They are as follows:
- Benign and malignant neoplasms.
- Hematologic diseases.
- Chronic kidney and liver disease.
- Cardiovascular pathology.
- Thyroid disease.
- Tuberculosis.
- Atherosclerosis of the brain.
- Inflammatory processes in the acute stage.
- Dry dermis.
- Body temperature is above 38 degrees.
UV quartz lamps for room disinfection
This type of medical device is a medical device. Ultraviolet rays have the following effect:
- destroy pathogenic microorganisms;
- activate the production of vitamin D;
- normalize metabolic processes in the human body;
- support and strengthen immunity.
The use of quartz lamps is indicated for preventive purposes in the autumn-winter period.
Indoor disinfection lamp: home use
Indications for use of the device:
- a newborn or preschooler in the house;
- the presence of frequently ill children or adults suffering from infectious, colds, dermatological, allergic diseases.
The effectiveness of ultraviolet lamps has been proven in the following pathological conditions:
- rhinitis;
- tonsillitis;
- pharyngitis;
- bronchitis;
- tuberculosis of the dermis;
- fractures;
- wounds;
- diseases of the female genital area.
The benefits and harms of ultraviolet lamps
Medical UV lamp for disinfection of rooms in hospitals and clinics is a good tool for the prevention and destruction of pathogens of various diseases. Its useful properties are used in children's practice, as well as in the treatment of diseases:
- dermatological;
- dental;
- musculoskeletal system;
- ear-throat-nose.
If the operating rules are not followed, the benefit of using an ultraviolet lamp is reduced to zero.
Quartzing
This term refers to the processing of ultraviolet radiation of a bactericidal or quartz lamp of surfaces and air in rooms, objects, medical instruments, the human body or its individual sections. The air is enriched with poisonous ozone as a result of quartzing, so during the procedure you should leave the room, and after completion - ventilate. Operation of the devices in strict accordance with the instructions does not harm. Failure to comply can cause unwanted side effects, such as an eye burn. Quartzing is used both in medical institutions and at home. However, science does not stand still, and in the modern world they use blue lamps to disinfect rooms, which are safe for living organisms and can be turned on in the presence of people.
Quartzing a person: instruction
When using the lamp, protect the cornea with special glasses, which are sold with the device. The area of the dermis to be irradiated is treated with a tanning agent, which is applied in a thin layer. Other parts of the body are covered with any tissue. A lamp preheated for five minutes is brought to the skin at a distance of at least 50 cm. The course of treatment is no more than five days. The duration of the first procedure should not exceed 30 seconds. Subsequently, the time gradually increases and reaches 180 seconds to the last session. The rays should fall on the treated area at a slight angle. The patient during the manipulation feels heat. After the procedure, rest is necessary. The best time for it is before bedtime.
Use of a blue lamp in the treatment of children
For colds and rhinitis in children under 3 years of age, the use of this product is possible. The procedure should be carried out during the sleep of the child, after protecting his eyes, putting a diaper on them. The treated area of the body should be warm, not hot.
Precautions:
- after quartzizing, ventilate the room;
- use glasses to protect the cornea from burns;
- Do not touch the open surface of a heated appliance;
- Do not look at the lamp on;
- the duration and time of quartzing is prescribed only by the attending doctor;
- use of the device for tanning is contraindicated;
- the presence of cracks, dry skin and dilated vessels are contraindications to the use of quartz lamps;
- when unpleasant sensations appear, the procedure is stopped.
UV lights
Today, buying a UV lamp is as easy as any other lighting fixture. Ultraviolet lamps are successfully used for disinfection:
- premises;
- furniture (cabinets, tables, racks, etc.);
- window sills;
- water;
- clothes;
- household items.
Varieties of bactericidal irradiators
Quartz lamps are:
- Ozone Free . Modern devices that form the minimum amount of ozone, which is absolutely harmless to living organisms.
- Ozone . After using them, it is necessary to ventilate the room.
Types of medical devices:
- Open irradiators . Principle of action: it is precisely the space where the light flux from the device gets disinfected. An open type ultraviolet lamp is used to disinfect rooms and ozonize objects and furniture without the presence of people.
- Recirculators . In such devices, the bactericidal quartz lamp is securely hidden under a protective casing, which prevents the penetration of ultraviolet rays outside. These products are safe for humans and can be used at home.
- Combined model. This type of irradiator works both in open and in closed mode.
- Special They are used in medicine for medical procedures, for example, for hardening fillings or warming up the sinuses.
Disinfection of air and objects indoors using a quartz lamp can prevent the spread of various infectious diseases. Having studied the features and technical characteristics, you can choose the best lamp for disinfection of the room in the presence of people for home use.
