  • Absorber switch locking device
    Patent number: 5682876
    Abstract: A locking device is disclosed for attachment to an absorber used in an anesthesia system and which provides assurance that the bag to ventilator switch cannot be put in the ventilator position for those applications where a ventilator is not intended to be used, i.e. MRI applications. As a further feature, the locking device also physically prevents the ventilator input to the bag to ventilator switch from being occluded, either by a protective plastic shipping cap or by having tubing or other conduits connected thereto.
