Medical Oxygen Cylinder Pressure Regulator Appraisal

Medical Oxygen Cylinder Pressure Regulator

This is a portable medical oxygen regulator, specifically a 'click-style' flowmeter designed for use with ambulatory oxygen tanks. The device is constructed primarily from brushed aluminum and features a black high-impact plastic control knob at the top for selecting flow rates (measured in liters per minute). It is equipped with a CGA 870 yoke connection, which includes a T-handle or toggle screw on the reverse (partially obscured) used to secure the regulator to the tank valve post. A prominent circular analog pressure gauge is mounted on the front, featuring a white face with color-coded zones: green for 500-3000 PSI indicating a full tank, and a red segment for low pressure. The gauge explicitly displays the word 'OXYGEN' and the warning 'USE NO OIL.' There is a standard metal barbed outlet port extending from the top section for connecting oxygen tubing. In terms of condition, the aluminum body shows minor surface scuffs and handling marks, but the gauge crystal appears clear and intact. This style of regulator is characteristic of modern medical equipment produced within the last 10-15 years, emphasizing lightweight portability for home healthcare and emergency use.
