Invacare® ML6, M9 and D Cylinder with Post Valve
8 Technical Data
8.1 Technical Description
The Invacare Oxygen Post Valve Cylinder Assembly is an oxygen
storage product that can deliver up to 2 L/min of continuous flow
oxygen to the patient via a nasal cannula. The cylinder assembly is
designed to store compressed oxygen up to 2,100 psig (14479 kPa).
The continuous flow conserver/regulator reduces the pressure at the
cannula connection to 50 psig (345 kPa) and contains a rotary flow
dial that is used to adjust the oxygen flow rate to the prescribed
setting. The cylinder assembly is filled with USP 93±3% oxygen using
its proprietary fill port that allows filling only through the use of an
Invacare HomeFill System. The duration of oxygen flow between fills
is dependent on the size of the cylinder and the flow setting.
