Respiratory tract humidifiers for medical use - Particular requirements for respiratory humidification systems
|Publication Date:||1 February 2010|
|ICS Code (Anaesthetic, respiratory and reanimation equipment):||11.040.10|
IEC 60601-1:1988, Clause 1, applies, except as follows:
Amendment (add at the end of 1.1):
This International Standard includes requirements for the basic safety and essential performance of humidification systems, as defined in 3.6. This International Standard also includes requirements for individual devices specified for use in humidification systems such as heated breathing tubes (heated-wire breathing tubes) and devices intended to control these heated breathing tubes (heated breathing tube controllers). ISO 5367 specifies other safety and performance requirements for breathing tubes.
NOTE Heated breathing tubes are medical electrical equipment and are subject to the requirements of IEC 60601-1.
* This International Standard also includes requirements for active HME (heat and moisture exchanger) devices, which actively add heat and moisture to increase the humidity level of the gas delivered from the HME to the patient. This International Standard is not applicable to passive HMEs, which return a portion of the patient's expired moisture and heat to the respiratory tract during inspiration without adding heat and moisture. ISO 9360-1 and ISO 9360-2 specify safety and performance requirements for passive HMEs and describe methods for testing performance.
Respiratory tract humidifiers can be
This International Standard is not applicable to devices commonly referred to as "room humidifiers" or humidifiers used in heating, ventilation and air conditioning systems, or humidifiers incorporated into infant incubators.
This International Standard is not applicable to nebulizers used for the delivery of drugs to patients.
In the planning and design of products within the scope of this International Standard, it is advisable to give due consideration to the environmental impact from the product during its life cycle. Environmental aspects are addressed in Annex GG.
NOTE Additional aspects of environmental impact are addressed in ISO 14971.
