12、initionsFor the purposes of this standard, the following definitions apply:3.1 adapter: Separate device, components, integrated fixtures, or other means or mechanisms, which permit afunctional connection between two incompatible devices.NOTEPresently, adapters that allow a functional connection betw
13、een enteral feeding sets and rigid female luer 2000 Association for the Advancement of Medical Instrumentationconnectors are sold, given away, or provided to users by original manufacturers or other (third) parties.3.2 compatible: Allowing a functional connection.3.3 connector: An integral component
14、 of the enteral feeding set that joins the set to the enteral access device.3.4 enteral feeding: Nutrition support for patients using liquids as a substitute for solid food that involvesdelivery of nutrient liquids into the alimentary tract (stomach, duodenum, or jejunum) using specializedtubesinclu
15、ding but not limited to nasoenteral, gastrostomy, jejunostomy, or oesophagostomy tubes. Feeding isadministered by an enteral pump or gravity.NOTEThe word “enteral“ specifically excludes delivery of liquids into an artery or vein.3.5 parenteral administration: Delivery of a specialized fluid or medic
16、ine specifically and only into a vein orartery; sometimes referred to as “IV” or “intravenous” delivery.3.6 set: A system that consists of tubing and other components through which fluids are delivered to either anenteral or parenteral access device.4 Requirements4.1 Elimination of adaptersAdapters
17、that are provided with, or for use with, enteral feeding sets shall not allow the direct or functionalconnection of an enteral feeding set to a rigid female luer connector. Examples of connections that shall not bepossible by use of an adapter include but are not limited to the following:a) enteral
18、feeding set to a parenteral administration set;b) enteral feeding set to an indwelling intravenous catheter or port;c) enteral feeding set to an epidural catheter;d) enteral feeding set to balloon inflation ports.4.2 Enteral feeding set connectorsEnteral feeding set connectors shall not be compatibl
19、e with rigid female luer connectors that meet ANSI/HIMAMD 70.11983, ISO 594/1, and/or ISO 594/2.5 TestsCompliance with 4.1 and 4.2 can be verified by inspection.Annex A(Informative)Rationale for the development and provisions of this standardThe purpose of enteral adapters is to provide a means to c
20、onnect enteral feeding sets to enteral access devices(e.g., jejunostomy tubes), which are constructed with rigid luer taper connectors that meet the AmericanNational Standard (now withdrawn), Luer taper fittings and performance (ANSI/HIMA MD 70.1-1983);International Standard Conical fittings with a
21、6 percent (luer) taper for syringes, needles and certain othermedical equipmentPart One: General requirements (ISO 594/1) and/or International Standard Conical fittingswith a 6 percent (luer) taper for syringes, needles and certain other medical equipmentPart Two: Lockfittings (ISO 594/2).Some enter
22、al access devices are constructed with rigid luer taper connectors, and one unintended consequenceof these adapters is that they provide a link between two unrelated systems, i.e., enteral to intravenous (IV). 2000 Association for the Advancement of Medical InstrumentationThese systems are intended
23、to have unique methods of delivery, with distinctly different purposes, which theseadapters can circumventpossibly resulting in harm or serious injury to the patient.In 1993, the AAMI Enteral Feeding Set Working Group began developing this standard in an effort to minimizethe possibility of potentia
24、lly harmful connections occurring between enteral feeding sets and indwelling IVports, catheters, peritoneal catheters, and tracheostomy tubes.It is intended that this standard will result in changes to the design of enteral feeding sets so that, within 6months, all new enteral feeding sets will be
25、incompatible with rigid IV female luers.In addition to encouraging manufacturers to eliminate the use of rigid female luer connectors on enteral feedingaccess devices, the working group hopes that this standard will help educate users about the potential risk topatients of using enteral adapters alr
26、eady in their facility.The ultimate goal is the prevention of any reasonable likelihood of connections between enteral feeding sets anddevices other than enteral access devices.In light of the serious risk involved, it was decided not to delay this functional standard for want of exactphysical and d
27、imensional specifications. However, the committee may eventually add dimensional requirementsand requests that manufacturers provide the working group, via the AAMI Standards Department, withinformation about physical dimensional requirements that they have developed and permission to use same in afuture edition of this standard. 2000 Association for the Advancement of Medical Instrumentation
