21、-3:2001+A1:2009 (E) 4 1 Scope This part of this European Standard specifies minimum performance and safety requirements for air entrainment devices used for delivery of a designated oxygen concentration to patients. It gives a test method to check the oxygen concentration in the air/oxygen mixture g

22、enerated by the air entrainment device. It also specifies marking requirements and gives an optional system of colour coding to assist the user to identify the designated oxygen concentration. This standard does not cover air entrainment devices which are integral with medical devices specified in o

23、ther standards e.g. emergency lung ventilators, humidifiers, nebulizers, etc. 2 Normative references This European Standard incorporates by dated or undated reference, provisions from other publications. These normative references are cited at the appropriate places in the text and the publications

27、ce Device consisting of a jet orifice (to which the oxygen supply is connected) adjacent to a series of air entrainment ports, the distal end of the device being designed for connection to an oxygen delivery system supplying a patient. NOTE These devices are sometimes described as Venturi devices. T

28、his term has been avoided as very few actually use the venturi principle. 4 Oxygen supply The device shall be designed to operate with an oxygen supply controlled by a flowmeter control valve capable of delivering at least 15 l/min of oxygen and complying with EN 738-1 and prEN 13159. 5 Connections

29、5.1 Oxygen supply inlet The inlet for oxygen to the air entrainment device should be a nipple conforming to prEN 13544-2. BS EN 13544-3:2001+A1:2009EN 13544-3:2001+A1:2009 (E) 5 5.2 Air inlet attachments Any air inlet attachment provided with or recommended for use with the air entrainment device sh

30、all neither affect the safety nor the performance of the device nor cover any marking of the device.

38、tration on air entrainment devices, the colour code given in Table 2 shall be used. The colour codes shall be applied directly to the air entrainment device and shall have an area of at least 1 cm 2 . The colour coding shall either be visible through the immediate external packaging or shall be repe

39、ated on the outside of the immediate external packaging.
