This European Standard specifies requirements for construction, dimensions and marking for the connectors in gas sampling tubes which transfer gas from the breathing system of anaesthetic and respiratory equipment to diverting gas monitors and back to the breathing system and/or to the anaesthetic gas scavenging system
(AGSS).
This European Standard gives requirements for the following gas sampling tube ports and connectors:
Gas sampling port on breathing system.
Gas return port on breathing system and AGSS.
Gas sampling and return ports on monitors.
Gas sampling tube inlet and outlet connectors.
Gas return tube inlet and outlet connectors.
This European Standard does not apply to connection ports intended for connection of sensors in the breathing system.
NOTE 1: It is expected that requirements for the application of this standard will be included in particular standards for specific medical devices and accessories.
NOTE 2: One important consideration is that gas sampling tube connectors are secure but nevertheless can be disconnected by the operator. EN 1707 includes requirements and test methods for separation force, unscrewing torque and air leakage.
According to EN 1707, Luer lock fittings are intended to be used for syringes, needles and certain other medical equipment. In order to minimize the risk of mis-connections, this standard specifies the arrangements of male and female fittings and the marking requirements to identify the different connectors, ports
and tubes. Tables 1 to 4 specify the type of Luer lock fitting that is used in actual applications.
NOTE 3: Another important consideration is that the ports in the breathing system can be sealed when gas sampling tubes are not connected.
Diese ÖNORM legt Anforderungen und Maße für Verbindungsstücke in Gasprobenentnahmeschläuchen fest, die das Gas vom Atemsystem eines Anästhesie- und Beatmungsgerätes zu einem ableitenden Gasüberwachungsgerät und zurück zum Atemsystem und/oder zum Anästhesiegas-Fortleitungssystem leiten.
