Aerosol Inhaler

An aerosol inhaler is a device that is used to inhale medications in the form of an aerosol or fine powder. This inhalation method is the most effective and safe for the treatment of various respiratory diseases, such as bronchial asthma, chronic bronchitis, pneumonia and others.

An aerosol inhaler consists of several main components:

– An air compressor that creates a stream of air under pressure.
– An aerosol generating device that converts the drug into small particles.
– A filter to clean the air from large particles that can damage the respiratory tract.
– A nebulizer that delivers an aerosol into the patient’s respiratory tract.

The principle of operation of an aerosol inhaler is that the drug is converted into a fine powder or aerosol, which is then inhaled by the patient through a nebulizer. Aerosols generated when using an inhaler have a particle size of less than 5 microns, which allows them to penetrate deep into the respiratory tract and reach the lungs.

The advantages of the aerosol inhaler include high treatment efficiency, rapid achievement of therapeutic effect, minimal environmental impact and no side effects. In addition, aerosol inhalation can be carried out anywhere where there is access to electricity and air, making it convenient for use at home.

However, like any medical device, an aerosol inhaler has its limitations and contraindications. For example, it may not be effective in treating conditions that produce large amounts of sputum or if you have allergies to medications. It is also important to use the inhaler correctly and follow the instructions for use to avoid possible complications.

Overall, the aerosol inhaler is an important tool in the treatment of respiratory diseases and has many advantages over other inhalation methods. However, its use must be strictly controlled and carried out under the supervision of a physician.

**Inhalation** - the introduction of medicinal substances into the respiratory tract for therapeutic or prophylactic purposes through the mouth, nose or through special devices - inhalers. Inhalations became widespread in the second half of the 19th century, when S.P. Botkin and J. Simpson discovered the beneficial effects of inhaling water vapor with essential and ammonia oils, chlorine, and lime chloride on the course of tuberculosis. In 1867, A. Cheshey argued that inhaling carbon dioxide salts, which restore the composition of their blood, was enough to treat children. E. Kussmaul (1871) sprayed medicinal substances mixed with air for more effective and rapid action. However, truly effective inhalation as a treatment method began to develop in the 70s of the 19th century. thanks to the appearance of a special device - an inhaler, created by K. Greenbeck (1902). Investigating the mechanism of inhalation, G. F. Lang (1892) showed that only solutions or suspensions can be absorbed at the same time. Therefore, special devices were developed - sprayers (early designs were created by E. Klebs - 1917). One of the first inhalation devices was L. Savartak’s device with a variable-volume reservoir. Somewhat later, I. Pak’s model with a constant tank volume appeared. From the second quarter of the 20th century. Inhalers created by J. Losle (1933) and D. Lask (1946) are widely used.

**Inhalation devices** are a medical device for carrying out inhalation therapy, which is carried out by inhaling or exhaling the contents of a special container into the oral cavity, nasal passages or trachea. The devices are used for the prevention and treatment of respiratory diseases, including diseases of the respiratory system, lungs and bronchi. Modern devices differ from each other in power, performance, and comfort of use.
