FIELD: medicine.
SUBSTANCE: invention refers to medical equipment, particularly to a pressure balance device for flask access and a method for aerosol entrapment in flask access with a pierced packing; closed and hermetic recovery of the flask moisture content is provided. A rigid container of the fixed internal volume is coupled with a vent pipe extending into the flask. When the flask pressure increases, it is balanced due to the volume variation of a compartment built in the rigid container. Said compartment comprises a pressure balance device which automatically varies the volume of the flask pressure balance compartment built in the rigid container by increasing or decreasing the compartment volume.
EFFECT: volume adjustment device represents either a movable disk, or an inflammable cylinder compressed with increasing the volume in the container and extended with decreasing the volume.
