YY/T 1665-2019 Vibratory and pat sputum excretion machine

Scope

This standard specifies the classification, components, requirements, and test methods for vibration percussion expectorant machines (hereinafter referred to as the equipment). This standard applies to devices driven by electric motors, which use a flexible shaft to generate vibrations through an eccentric device in the power head to percuss the patient's local chest area and assist in the expulsion of respiratory tract secretions. For a multi-functional device (e.g., with a nebulizer function), the content specified in this standard only applies to the expectorant function based on the vibration percussion principle of the equipment. For other functions, if there are corresponding national standards and/or industry standards, they should also comply with the requirements of other relevant standards. This standard does not apply to pneumatic pulse oscillation expectorant machines.
