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.
BSI recommends this version of standard for organisations operating in or with the UK. The ISO edition is available here if required.
