F-50 Gas Vent/Filter Assembly
The DI-55, D/DI-65HL, D/DI-75, D/DI-150, and D/DI-350 Disposable
Administration Sets contain the F-50 Gas Vent/Filter Assembly.
The F-50 GasVent/Filter Assembly utilizes a float assembly contained in
a fluid chamber to prevent air from entering the patient line. As the
Disposable Set primes, fluid fills the fluid chamber raising the float
assembly to allow fluid to flow to the patient. Any air in the line during
priming is vented through a hydrophobic filter membrane. During
normal operation, fluid passes through a particle filter, into the fluid
chamber and to the patient line. When air enters the F-50 Gas
Vent/Filter Assembly, the volume of fluid in the fluid chamber decreases
causing the float assembly to drop down and close the fluid path, which
stops flow to the patient. Air in the fluid chamber is vented through the
hydrophobic membrane (gas vent) located under the vent cap. After air
has vented out and fluid re-enters the fluid chamber, the float assembly
rises to open the fluid path and resume flow to the patient.
