Medical devices — Non-electrically driven portable infusion devices
This document specifies essential requirements and related test methods for non-electrically driven portable infusion devices, thereafter called "device". It is applicable to devices designed for continuous (fixed or adjustable) flow and/or for bolus neuraxial and intravascular or hypodermic applications. NOTE Sites for the neuraxial application include the spine, intrathecal or subarachnoid space, ventricles of the brain and the epi-, extra- or peri-dural space. Neuraxial application anaesthetics can be administered regionally, affecting a large part of the body, such as a limb, and include plexus blocks, such as the branchial plexus blocks or single nerve blocks. Neuraxial application procedures include continuous infusion of wounds with local anaesthetic agents. These devices can be used in health care and non-health care settings. They can be applied or administered by health care professionals or by the intended patient. These devices can be pre-filled by the manufacturer or filled before use by a health care professional or the intended patient. This document does not apply to — electrically driven or electrically controlled infusion pumps that are covered by IEC 60601-2-24, — devices for single patient use intended to deliver discrete volumes (bolus) of medicinal product that are covered by the ISO 11608 series, — implantable devices, — enteral devices, — transdermal delivery devices, and — devices where the energy for infusion is not provided by the device or through active intervention by the patient (e.g. devices only powered by gravity).

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 (see www .iso .org/ directives).
Attention is drawn to the possibility that some of the elements of this document may be the subject of
patent rights. ISO shall not be held responsible for identifying any or all such patent rights. Details of
any patent rights identified during the development of the document will be in the Introduction and/or
on the ISO list of patent declarations received (see www .iso .org/ patents).
Any trade name used in this document is information given for the convenience of users and does not
constitute an endorsement.
For an explanation of the voluntary nature of standards, the meaning of ISO specific terms and
expressions related to conformity assessment, as well as information about ISO’s adherence to the
World Trade Organization (WTO) principles in the Technical Barriers to Trade (TBT) see www .iso .org/
iso/ foreword .html.
This document was prepared by Technical Committee ISO/TC 76, Transfusion, infusion and injection, and
blood processing equipment for medical and pharmaceutical use.
This second edition cancels and replaces the first edition (ISO 28620:2010), which has been technically
revised. The main changes compared with the previous edition are as follows:
— the Scope has been amended to explicitly cover neuraxial and intravascular or hypodermic
applications;
— the requirements on components and their fittings have been aligned with the appropriate parts of
the ISO 80369 series, i.e. ISO 80369-1, ISO 80369-6 and ISO 80369-7;
— the requirements on filter and tubing have been updated;
— a test method for the efficiency of the fluid filter has been added;
— Table 1, which gives information to be provided by the manufacturer, has been updated.
Any feedback or questions on this document should be directed to the user’s national standards body. A
complete listing of these bodies can be found at www .iso .org/ members .html.

These devices can be pre-filled by the manufacturer or filled before use by a health care professional or
the intended patient.
This document does not apply to
— electrically driven or electrically controlled infusion pumps that are covered by IEC 60601-2-24,
— devices for single patient use intended to deliver discrete volumes (bolus) of medicinal product that
are covered by the ISO 11608 series,

4 General requirements
4.1 Components
The device shall contain the following components:
— means to convert non-electric energy into fluid flow;
— a flow restrictor;
— a reservoir designed to contain the solution to be administered;
— a particulate matter filter in the fluid path.
NOTE 1 These components can be integrated or delivered separately.
The device may also contain one or more of the following components (non-exhaustive list):
— a system to adjust the flow rate;
— a filling port preferably with check valve;
NOTE 2 The filling port is intended for use in the pharmacy during filling only and can be a Luer type
female geometry in accordance with ISO 80369-7.
— a lock connector at the distal end of the tubing conforming to ISO 80369-6 or ISO 80369-7, as
appropriate for the intended application;
— a clamp to stop the flow if necessary;
— a sterility protector, e.g. Luer cap, at the distal end of the tubing and of the filling site;
— a system to administer a bolus with a means for controlling the maximum amount of solution
infused over time;
— a protective element of the reservoir, preventing the drug solution from flowing out should the
reservoir break or leak (which can be necessary to fulfil the leakage test in 6.4 and 6.5);
— a means of indicating the end of infusion;
NOTE 3 This can be achieved by a visual, audible or other indication.
— administration tubing;
