Abstract

This document specifies particular requirements for portable units which are part of a transportable liquid oxygen system and used to provide a controlled flow of oxygen for inhalation by the patient in the home-care environment.

Portable units are intended to be used without professional supervision, carried by patients while moving around and during their off-site activities and refilled from a base unit via a transfilling device through the portable unit’s filling port connector.

NOTE            Requirements that are common to both portable units and base units are specified in ISO 18777-1.
