FIELD: medicine.
SUBSTANCE: apparatus accommodates a respiratory head with a respiratory pipe connected to the patient. Said respiratory pipe is connected through valve package to an intake duct connected with a balloon assembly for air feeding to the patient through the respiratory pipe and to one or more offtakes for exhaled air tapping to the environment. The balloon assembly comprises an elastic bag with an inlet and outlet. In addition, the bag outlet contains a unidirectional valve. The bag outlet is coupled with the intake duct of said respiratory head. The balloon assembly is supplied with an excess pressure protection frame discharging the air from the bag at excess pressure. There are disclosed balloon assembly and valve box to be applied in the apparatus.
EFFECT: inventions eliminate risk of pulmonary overextension.
