Abstract
An anesthesia machine includes a gas mixer providing gas for delivery to a ventilated patient and a breathing system. The breathing system includes a reusable ventilation portion and a disposable circle portion. The reusable ventilation portion includes a mechanical ventilation section, a manual ventilation section, a ventilation port, and switch configured to switch between connection of the mechanical ventilation section and the manual ventilation section to drive patient ventilation. The disposable circle portion includes a vent connector that connects to the ventilation port, an inspiratory channel, and a gas intake port providing anesthetic gas from the gas mixer to the inspiratory channel. The disposable circle portion further includes an expiratory channel, a COabsorber, and a filter positioned in a flow path between the expiratory port and the vent connector and between the COabsorber and the vent connector. The filter is configured to prevent moisture and bacteria from entering the reusable ventilation portion of the breathing system.
