GB/T 45897.1-2025 Pressure regulators for use with medical gases—Part 1:Pressure regulators and pressure regulators with flow-metering devices
Abstract
This document specifies the design, structure, type testing, and marking requirements for pressure regulators intended for use in patient treatment, management, diagnostic assessment, and care, as well as for medical gases and their mixtures or gases used to drive surgical instruments (see 3.17).
Examples: Gases include oxygen, medical air, and oxygen/nitrous oxide (laughing gas) mixtures.
Pressure regulators applicable to this document:
a) Intended to be connected to gas cylinders by operators;
b) Intended to be connected to gas cylinders by operators and equipped with integrated flowmeter devices;
c) Components of medical equipment (such as anesthesia workstations, ventilators, resuscitators).
Pressure regulators can provide pressure outlets or flow outlets and can be adjusted or preset.
Pressure regulators are intended for installation on rechargeable gas cylinders with a working pressure of up to 30,000 kPa (300 bar) and can provide devices for controlling and measuring the flow of medical gases delivered.
