ANESTHETIC BREATHING APPARATUS AND INTERNAL CONTROL METHOD FOR SAID APPARATUS
First Claim
1. An anesthetic breathing apparatus comprising:
- a breathing circuit having an inspiratory gas output port and an expiratory gas input port and an exhaust;
a control unit configured to set said breathing circuit selectively in a first mode of operation to provide inspiratory gas, fresh gas and/or breathing gas recirculated in said breathing circuit, via said inspiratory gas output port, and to enable recirculation into said breathing circuit and/or evacuation via said expiratory input port for manual or mechanical ventilation by said anesthetic breathing apparatus;
said control unit being configured to set said anesthetic breathing apparatus selectively in a second mode of operation to provide a flow of fresh gas via a fresh gas output port to an external breathing system connected thereto, and to disable recirculation and/or evacuation via said expiratory input port; and
a gas scavenger fluidly connected to the exhaust of said breathing circuit via a separate gas input port of the anesthetic breathing apparatus for gas scavenging via said anesthetic breathing apparatus.

Abstract
An anesthetic breathing apparatus has a breathing circuit having an inspiratory gas output port and an expiratory gas input port, and a control unit that sets the anesthetic breathing apparatus selectively in a first mode of operation to provide inspiratory gas, fresh gas and/or breathing gas recirculated in said breathing circuit, via said inspiratory gas output port, enable recirculation into said breathing circuit and/or evacuation via the expiratory input port for manual or mechanical ventilation by said anesthetic breathing apparatus. The control unit is also able to set the anesthetic breathing apparatus selectively in a second mode of operation to provide a flow of fresh gas via a fresh gas output port to an external breathing system connected thereto, disable recirculation and/or evacuation via the expiratory input port. An exhaust of the breathing circuit is connected to a gas input port of the anesthetic breathing apparatus for gas scavenging via said anesthetic breathing apparatus.

12. A method of internally controlling an anesthetic breathing apparatus, said method comprising:
-
selectively setting said anesthetic breathing apparatus in a mode of operation, comprising providing a flow of fresh gas via a fresh gas output port to an external breathing system connected thereto, disabling recirculation and/or evacuation via an expiratory input port of said anesthetic breathing apparatus; and connecting an exhaust of an external breathing system to a gas input port of said anesthetic breathing apparatus for gas scavenging via said anesthetic breathing apparatus.

13. A computer-readable medium loadable into a control unit for internally controlling an anesthetic breathing apparatus, comprising programming code causing said control unit to selectively set said anesthetic breathing apparatus in a mode of operation, for:
-
providing a flow of fresh gas via a fresh gas output port to an external breathing system connected thereto; disabling recirculation and/or evacuation via an expiratory input port of said anesthetic breathing apparatus; and wherein an exhaust of an external breathing system is connected to a gas input port of said anesthetic breathing apparatus for gas scavenging via said anesthetic breathing apparatus.
