FIELD: medicine.
SUBSTANCE: group of inventions refers to medicine. An inhaler comprises a body which represents a drug container, a compressed gas jet nozzle and a fluid passage connected with the container and used to supply the drug directly to the jet to produce an aerosol drug. Additionally, the inhaler can comprise an inlet hole connected with the body and used to supply the aerosol to the patient, an entrapping passage used to entrap an respiratory flow from atmosphere and a control passage connected via a fluid medium with the fluid passage and used to supply a control gas into the fluid passage for prevent the drug from supplying directly to the jet. The control passage can contain a gas tube neighbouring the entrapping passage. The entrapped respiratory flow in the entrapping passage prevents substantially the control gas flow through the entrapping passage to finish control gas supply to the fluid passage.
EFFECT: group of inventions allows minimising a number of movable parts that simplifies manufacturing of the inhaler.
