PATIENT BREATHING SYSTEM
First Claim
1. A patient breathing system, comprising:
- a ventilator configured to provide a driving gas flow to generate patient inspiration, the ventilator further including a gas inlet configured to drive gas,wherein the patient breathing system is connectable to a circle comprising that includes an inspiratory hose and an expiratory hose connected that are each configured to connect to a patient, through which circle expired gases can be circulated back to the patient, thereby wherein the circle further comprises a fresh gas inlet, an arrangement for enabling the gas flow in a desired direction, a unit for removal of the exhaled carbon dioxide, and a ventilator port for the ventilator connection; and
an arrangement by which driving gas of the ventilator has been separated from the patient gases flowing in the circle,wherein the arrangement separating the driving gas of the ventilator and the patient gases flowing in the circle is formed by an extended gas pathway between the circle and the ventilator.
