YY/T 1685-2020 Pneumatic impulse oscillation equipment for sputum excretion
Basic Information
Scope
This standard specifies the terms and definitions, classification and composition, requirements, and test methods for pneumatic pulse oscillation expectoration equipment (hereinafter referred to as the equipment).
This standard applies to equipment that uses pulse airflow generated by an air pulse airflow generator, which is delivered through an air supply hose into an inflatable airbag to act on the chest cavity and assist in the removal of respiratory tract secretions. For a multi-functional device (such as those with nebulizer functions), the content specified in this standard only applies to the expectoration function based on the pneumatic pulse oscillation principle of the device. Other functions, if there are corresponding national standards and/or industry standards, should also comply with the requirements of other relevant standards.
This standard does not apply to vibration percussion expectoration machines.
