Endotracheal tube/ mask connector plug
Used for placing the endotracheal tube/ mask connector. Meanwhile the plug blocks the
breathing circuit, it’s useful for system leak detection, adjusting system pressure and
flushing circuit.

absorbent canister
The absorbent canister is filled with a granular carbon dioxide absorbent material eg. soda
lime. It uses a coaxial gas flow path to provide for more efficient use of absorbent, while
reducing flow resistance. The chemical reaction that takes place in the canister creates heat
and humidity, which is added to the delivery of anesthesia to the animal.

Vaporizer
The vaporizer is the most complicated and expensive part of the anesthesia system. More
attention should be paid to its maintenance and operation. It converts a liquid anesthetic
agent into a vapor which is added to oxygen. The anesthetic vapor is measured in volume
percent (vol %). A dial on top of the vaporizer allows the operator to select the amount of
vapor administered to the animal. The coiled pipe design inside the vaporizer ensures the
output is not affected by the fluctuation of pressure, temperature and gas flow. The inner
design of the vaporizer is different according to the anesthetic agent. Please use the correct
anesthetic agent following the tag on the vaporizer. The misuse may cause the damage to
the equipment and animal.

flush button
Press to deliver the oxygen directly to breathing circuit. It is generally used to flush the
anesthetic gas in system or in emergency.

Rebreathing circuit /Non-rebreathing circuit tube socket
Used for connecting to a non-rebreathing circuit, which is generally applicable to animals
below 7 kg.

Relief valve
Operator can determine the inspiratory pressure for ventilating the animal by adjusting the
valve while observing the system’s pressure gauge. When the pressure of gas mixture
exceeds the setting, the gas will be expired through valve to keep the pressure stable.
