DEVICE FOR RESPIRATORY DISEASES TREATMENT AND LUNG FUNCTION GAIN Russian patent published in 2017 - IPC A61M16/16 

FIELD: medicine.

SUBSTANCE: device for lung function improvement comprises the first gas flow path for inhalation, a housing and a space for fluid formed in the housing. The second gas path communicates with the housing and is designed to transfer the exhaled gas to the space for fluid. Vapour space is configured to receive vapour formed in the space for fluid, and the first gas path communicates with the vapour space. The mouthpiece for airflow direction from the first gas path to the user during inhalation, and for reception of gas exhaled by the user. Means to transfer the exhaled gas flow from the mouthpiece to the housing along the second gas path provides resistance to the exhaled gas flow passing through the second gas path, and increases the pressure in the space for fluid and vapour. The relief valve prevents an excessive rise in pressure inside the device during exhalation. The air replacement valve supplies air during inhalation of to replace air in the vapour space. Means for gas flow transfer during inhalation from the vapour space to the mouthpiece along the first gas path comprises the first valve to prevent gas from entering through the first gas path into the vapour space during inhalation, and to provide air supply from the vapour space to the mouthpiece through the first gas path. Means for exhaled gas flow transfer comprises the second valve capable of blocking the air flow in the second gas path during inhalation and allowing the exhaled gas to flow through the second gas flow path into the space for fluid. A method for lung function improval by the device and device and method application for hampered exhalation and inhalation.

EFFECT: combined hampered exhalation and vapour inhalation.
