Carbon dioxide absorber canister attachment

An arrangement for connecting a carbon dioxide adsorption canister to a patient breathing circuit of a ventilator, the arrangement comprising:

• a ventilator having a patient breathing circuit;
• a carbon dioxide adsorption canister;
• and
• an interface mechanism removably coupled to the ventilator and configured to removably connect the carbon dioxide absorption canister to the patient breathing circuit, the interface mechanism having
• a retainer that is connected to the ventilator and that has a passageway connected to the patient breathing circuit;
• a cradle that is coupled to the retainer and that is configured to receive and removably retain the carbon dioxide adsorption canister, the cradle being positionable between first and second positions relative to the retainer while remaining coupled to the retainer;
• wherein in the first position, the cradle is horizontally aligned with the retainer and in the second position the cradle is not horizontally aligned with the retainer;
• wherein the canister and the retainer have mating faces that mate together when the cradle is positioned in the first position;
• wherein in the first position the canister is coupled to the cradle and the mating faces are mated, and the canister is placed in fluid communication with the patient breathing circuit via the passageway of the retainer;
• and
• wherein in the second position the mating faces are not mated, the canister is not connected to the patient breathing circuit, and the cradle extends at an angle from the retainer and thereby provides visual indication when the canister is removed from the interface mechanism.
