CSA Preface This is the second edition of CAN/CSA-ISO 10079-3, Medical suction equipment - Part 3: Suction equipment powered from a vacuum or positive pressure gas source, which is an adoption without modification of the identically titled ISO (International Organization for Standardization) Standard 10079-3 (third edition, 2014-05-01). It supersedes the previous edition published in 2003 as CAN/CSA-Z10079-3, Medical suction equipment - Part 3: Suction equipment powered from a vacuum or pressure source (adopted ISO 10079-3:1999, with Canadian deviations). This Standard has been developed in compliance with Standards Council of Canada requirements for National Standards of Canada. It has been published as a National Standard of Canada by CSA Group. Scope This part of ISO 10079 specifies safety and performance requirements for medical suction equipment powered from a vacuum or positive pressure gas source generating venture suction. It applies to equipment connected to medical gas pipeline systems or cylinders and venturi attachments. Annex D illustrates the three parts of ISO 10079 by providing a schematic for typical systems. The equipment can be stand-alone or part of an integrated system. Additional requirements for suction equipment intended for field and/or transport use are included in this part of ISO 10079. This part of ISO 10079 does not apply to the following: a) central power supply (by vacuum/compressed air generation), piping systems of vehicles and buildings, and wall connectors; b) end-piece such as suction catheters, Yankauer sucker and suction tips; c) syringes; d) dental suction equipment; e) anaesthetic gas scavenging systems; f) laboratory suction; g) autotransfusion systems; h) closed systems for wound drainage; i) mucus extractors, including neonatal mucus extractors; j) ventouse (obstetric) equipment; k) breast pumps; l) liposuction; m) uterine aspiration; n) plume evacuation systems.
