Q BSI 12-2000 STDBBSI BS EN 1615-ENGL 2000 1624bb9 0885b84 489 Page 4 EN 1615:2000 Introduction This European Standard specifies requirements for single-use enteral feeding
18、 catheters and enteral giving sets and their connector systems. The requirements for enteral feeding catheters, giving sets and their connections are specified so that, when used in current clinical practice, these devices do not compromise the clinical condition or the safety of patients. Some gene
19、ral requirements are covered by reference to other European Standards listed in the normative references clause. This European Standard contains informative references to other European Standards listed in the Bibliography. Enteral feeding catheters are intended for human enteral nutrition. They are
20、 designed to pass the nutrition solutions through the nose or mouth, or by gastrostomy, jejunostomy or oesophagostomy. Both enteral giving sets and enteral feeding catheters are often used with enteral nutrition pumps. The performance and connecting system requirements are specified so that both dev
21、ices and their connections perform safely. It is important that enteral giving sets should not be able to be connected to parenteral intravascular catheters or any other catheter with a female Luer connector. The requirements for the connecting systems prevent this form of misconnection. There are m
22、any enteral giving sets and enteral feeding catheters on the market which perform satisfactorily. This standard specifies three connectors suitable for enteral giving sets. It has not been found possible or desirable to limit the standard to only one connector. This places the onus on the designers
23、and manufacturers of the enteral feeding catheters to provide connectors on their devices which mate with the connector on the enteral giving set and conform to the appropriate clauses of this standard. The report from the Task Force Group, Luer Fittings, under the auspices of the CEN Health Care Fo
24、rum has been noted. A revision of the present standard will be undertaken when an appropriate solution has been decided for alternative connector systems for enteral use. It was not considered necessary to provide a colour code on the enteral giving set, because the connectors specified for the ente
25、ral giving set will not fit into a female Luer fitting. Also, many enteral feeding catheters use a colour code on the connector to indicate the diameter of the catheter, and this could cause confusion with any colour suggested for coding the enteral giving set.

26、2000 Page 5 EN 1615:2000 I Scope This European Standard specifies requirements for the design and testing of single-use enteral feeding catheters, single-use enteral giving sets and their connection systems. Requirements for radiodetectable enteral feeding catheters are not given in this standard. N
27、OTE Enteral feeding catheters intended for insertion through the mouth or nose can be radiodetectable in their entirety or at the tip or by means of intermittent marks. At present there is no generally accepted standard test method for radiodetectability, but research to develop a standard method of
28、 test is being considered. 2 Normative references The following normative documents contain provisions which, through reference in this text, constitute provisions of this European Standard.

33、 6 EN 1615:2000 3 Terms and definitions For the purposes of this European Standard the following terms and definitions apply. 3.1 enteral giving set medical device by which nutrient or diet is transferred from a nutrient or diet container to an enteral feeding catheter (see Figure I) 3.2 enteral fee
34、ding catheter medical device consisting of a flexible tube having one or more eyes and a connector, designed to introduce nutrient or diet into the gastro-intestinal tract 4 Requirements 4.1 Enteral giving set The enteral giving set shall consist of at least the following: a) b) flexible tubing; eit
35、her an integral nutrient container or a means of effecting connection to a nutrient container; c) a connector to make a connection with an enteral feeding catheter. NOTE 1 The enteral giving set can also be provided with other features, e.g. a drip chamber, a pump insert, a means for regulating and/
36、or stopping the flow through the enteral giving set. NOTE 2 The means of connection between the enteral giving set and the nutrient container (if it is not integral) is preferably a screw fitting or a means different from the piercing pin system used for parenteral administration. 4. I. I Tensile pr
37、operties The flexible tubing part of the enteral giving set shall withstand a linear tensile force of 15 N without rupture or cracking when tested in accordance with EN 1618:1997, annex B. Any joints or connections within the enteral giving set shall also withstand a linear tensile force of 15 N. 4.
38、1.2 Connector on the enteral giving set The connector on the enteral giving set shall conform to one of the following requirements: a) it shall have the dimensions given in either Figure 2 (“Type A”) or Figure 3 (“Type BY; Q BSI 12-2000 Page 7 EN 1615:2000 b) c) it shall be a female 6 % (Luer) conne
39、ctor, slip or lock (7ype CD) conforming to EN 20594-1 or EN 1707; it shall be an alternative connection system (including both an enteral giving set and an enteral feeding catheter) (“Type D“) which passes the tests specified in 4.3 and 4.4, but does not connect with a female 6 % (Luer) connector, s
40、lip or lock as specified in EN 20594-1 or EN 1707, as appropriate. NOTE There are a variety of connectors on the market. This standard provides for connectors which provide safe connection to an enteral feeding catheter which has a connector designed to mate with it. The dimensions of the connector
41、shall not be altered by deformation when connection to an enteral feeding catheter is attempted. 4.1.3 Liquid leakage test 4.1 3.1 Sets designed for use with a pump Prior to testing for liquid leakage all the openings shall be sealed.
