Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing international standards is normally carried out
through ISO technical committees. Each member body interested in a subject for which a technical
committee has been established has the right to be represented on that committee. International
organizations, governmental and non-governmental, in liaison with ISO, also take part in the work.
ISO collaborates closely with the International Electrotechnical Commission (IEC) on all matters of
electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular the different approval criteria needed for the
different types of ISO documents should be noted. This document was drafted in accordance with the
editorial rules of the ISO/IEC Directives, Part 2. www .iso .org/directives

Introduction
During the development of the standard for enteral small-bore connectors (ISO 80369-3), it became
clear that the risk of misconnections was not limited to the patient access connectors and that the
whole enteral system needed to be considered. The possible misconnection between enteral feed
reservoir access connectors and the spikes typically used on intravenous administration sets was
also reviewed. However, as feed reservoir connectors are not exactly within the definition of small-
bore connectors, it was decided to develop a separate standard (ISO 18250-3) for these connectors,
taking into account the risks of misconnections with other devices such as intravenous (IV) bags.
During the development of ISO 18250-3, it became apparent that the ubiquitous intravenous spike was
specified in various ISO medical device standards but that the geometry and materials requirements
for the female port on the intravenous reservoir were not defined. However, the performance of this
female port was defined in various ISO standards.
This document, therefore, specifies the design, dimensions and materials for the female port. It makes
reference to existing performance standards. It also includes tests to validate that the spike and the
female port do not interconnect with the other reservoir connectors of the ISO 18250 series.
This document also includes analysis sufficient to include traditional Luer connectors of ISO 80369-7
as permissible reservoir connectors for intravascular applications.
This document is not a device standard as it specifies only the requirements of the interfaces for
connectors used in intravascular reservoirs and intravascular infusion sets.

INTERNATIONAL STANDARD ISO 18250-7:2018(E)
Medical devices — Connectors for reservoir delivery
systems for healthcare applications —
Part 7:
Connectors for intravascular infusion
1 *Scope
This document specifies the interface dimensions and requirements for the design and functional
performance of connectors intended to be used to connect intravascular infusion sets to
intravascular infusion reservoirs.
This document does not specify the dimensions and requirements for the medical devices or
accessories that use these connectors. Such requirements are given in particular international
standards for specific medical devices or accessories.
EXAMPLES Medical devices which may use intravascular reservoir connectors are the following:
— Administration ports on IV fluid reservoirs and the mating spikes of IV administration/intravascular
infusion sets/lines, e.g., IV bags/containers and the spike inlet ends of IV sets;
— Devices intended to be connected in series between the administration port of IV fluid reservoirs and the
mating spikes of IV administration/giving lines;
— Syringes and syringe IV sets utilizing Luer connectors.
The following connectors are excluded from the scope of this document:
— Stoppers for bottles as specified in ISO 8536-2;
— Compounding/admixture ports on IV reservoirs and intended mating devices.
EXAMPLES Rubber stoppers used for injection into the reservoir and the mating pharmacy admixture
devices (syringes, needles, reconstitution devices, and other ancillary equipment used to access the
compounding or admixture ports).
— The fill ports of non-powered (i.e. elastomeric) pumps.
NOTE 1 Details of alternative spikes that are in common use are located in Annex G for informational purposes.
NOTE 2 Manufacturers are encouraged to incorporate the connectors specified in this document into
intravascular infusion medical devices or accessories, even if not currently required by the particular
medical device standards. It is expected that when the particular medical device standards are revised,
requirements for reservoir connectors, as specified in ISO 18250, will be included.
