ISO 18777:2005规定了用作氧气治疗供应源的可运输液氧系统的安全性和基本性能要求。这些装置通常由在使用中由患者携带或携带的便携式装置组成，并且用于重新填充便携式装置的容器。这些设备主要用于家庭护理应用和保健设施/机构。这些设备经常在没有专业监督的情况下使用。 用作氧气管道系统供应源的液氧容器不在本国际标准之列

ISO 18777:2005 specifies requirements for the safety and essential performance of transportable liquid oxygen systems which are used as a supply source for oxygen therapy. These devices usually consist of a portable unit to be carried by or with the patient whilst in use and the vessel used to refill the portable unit. These devices are mostly used in home care applications and in health care facilities/institutions. These devices are often used without professional supervision. Liquid oxygen vessels used as a supply source for oxygen pipeline systems are excluded from this International Standard.
