An anesthetic system and a transportation ventilation system include a breathing circuit which is isolatable from ventilator machines and anesthesia machines. The breathing circuit is connectable to the patient and includes a respiration bag within an actuator bag which is translucent and inelastic.

An anesthetic system and a transportation ventilation system include a breathing circuit which is isolatable from ventilator machines and anesthesia machines. The breathing circuit is connectable to the patient and includes a respiration bag within an actuator bag which is translucent and inelastic. The ventilation machine supplies signals so that the respiration bag collapses and expands within the actuator bag through a multi-port valve structure.

An anesthesia system comprising: anesthesia machine means connected to an external gas source to receive gas therefrom, and connected to continuously supply a preselected mixture of gas, said anesthesia machine means have means to mix the gas received into said preselected mixture of gas; a disposable breathing circuit interconnectable between said anesthesia machine means and a patient, said disposable breathing circuit having: first connector means for connection to said anesthesia machine means to receive said preselected mixture of gas therefrom, second connector means for connection to said patient to supply and receive respiratory gas, reservoir means connected for receiving, storing and supplying said preselected mixture of gas and for receiving, storing and supplying said respiratory gas and for adding said preselected mixture of gas thereto, tube means interconnected between said first connector means, second connector means and said reservoir means to communicate said respiratory gas from said patient to said reservoir means upon expiration of gas from said patient and from said reservoir means to said patient upon inspiration of gas to said patient, and to communicate said preselected mixture of gas from said anesthesia machine means to said reservoir means, actuator means positioned operatively proximate to said reservoir means to urge said reservoir means between a collapsed first position in which said preselected mixture of gas and respiratory gas therewithin are supplied from said reservoir means to the patient via said tube means and an expanded second position in which the respiratory gas is expelled from the patient via said tube means and to receive said preselected mixture of gas via said tube means from said anesthesia machine means; excessive gas pressure relief means in communication with said respiratory gas and said preselected mixture of gas during all but the time said gases are being supplied from said reservoir means to the patient; and means operated by the flow of gases from the reservoir means to the patient for blocking communication of the excessive gas pressure relief means with the respiratory gas and the preselected mixture of gas during supply of said gases to the patient; and ventilation machine means for generating inspiration signals and expiration signals in accordance with a preselected pattern and removably connected to said actuator means to supply said inspiration signals and expiration signals thereto for urging said reservoir means between said first and second positions respectively.
