Abstract:
1. An anesthesia machine comprising: a controller; a scavenger hose configured to direct exhaled anesthetic agent from a patient and configured to pneumatically connect to a compressor that creates at least a partial vacuum to draw the exhaled anesthetic agent through the scavenger hose; a valve operatively connected to the scavenger hose, said valve configured to allow the transmission of the exhaled anesthetic agent through the scavenger hose in a first position and occlude the scavenger hose in a second position; a switch operatively connected to the valve and to said controller, said switch being configured to automatically turn on the anesthesia machine and cause the valve to operate such that the valve is in the first position when the switch is in a first state and automatically turn off the anesthesia machine and cause the valve to operate such that the valve is in the second position when the switch is in a second state; and a scavenger assembly operatively connected between the patient and the scavenger hose, wherein movement of the valve to the first position activates the scavenger assembly; wherein the position of the valve between the first position and second position corresponds to the state of the switch between the first state and the second state.
