ABSTRACT:
An anesthesia system for use in MRI suites is provided. The anesthesia system is connected between an anesthesia machine positioned outside the MRI suite and a patient positioned within the MRI suite. The anesthesia machine provides anesthesia gas mixture for anesthetizing the patient. The apparatus has a delivery mechanism for transporting the anesthesia gas mixture from the anesthesia machine to the MRI suite and a mechanism for introducing fresh room air into the anesthesia gas mixture thereby creating a combined gas mixture. A reservoir mechanism receives and stores at least a portion of the anesthesia gas mixture delivered through the delivery mechanism. A mechanism introduces fresh room air into the anesthesia gas mixture thereby creating a combined gas mixture. A ventilation mechanism receives and stores the combined gas mixture. A connector mechanism is mounted to the ventilation mechanism for receiving the combined gas mixture from the ventilation mechanism and a non-rebreathing mechanism inhibits rebreathing of patient exhalation by the patient. A first tube delivers the combined gas mixture from the connector mechanism to the patient and a second tube delivers exhalation from the patient to the non-rebreathing mechanism upon the patient exhaling with the non-breathing mechanism maintaining the patient exhalation from returning to the patient. Finally, a scavenger mechanism associated with the non-rebreathing mechanism releases patient exhalation from the non-rebreathing mechanism to a scavenger system.
