Resuscitation bag system with a gas control unit

1. A resuscitation bag system ( 1 ) useable for resuscitating a person in cardiac arrest, comprising:

a hollow flexible bag ( 54 ) comprising an inlet ( 54 a ) and an outlet ( 54 b ),

a first conduit element ( 56 ) fluidly connected to the inlet ( 54 a ) of the hollow flexible bag ( 54 ) for providing gas to said flexible bag ( 54 ), and

a main conduit ( 5 ) fluidly connected to the outlet ( 54 b ) of the hollow flexible bag ( 54 ) for conveying gas provided by said flexible bag ( 54 ), and

a gas control unit ( 90 ) comprising a first valve ( 92 ) fluidly connected to a first ( 922 ) and to a second conduit ( 923 ), said first ( 922 ) and second conduits ( 923 ) being arranged in parallel and further fluidly connected to the first conduit element ( 56 ), the first conduit ( 922 ) comprising a first flow restrictor ( 924 ) configured for limiting the gas flow to a first flowrate, and the second conduit ( 923 ) comprising a second flow restrictor ( 925 ) configured for limiting the gas flow to a second flowrate, said second flowrate being less than the first flowrate.

2. The resuscitation bag system ( 1 ) of claim 1 , wherein the first valve ( 92 ) of the gas control unit ( 90 ) is controlled by a monitoring module ( 70 ) adapted to direct the gas into the first conduit ( 922 ) or the second conduit ( 923 ).

3. The resuscitation bag system ( 1 ) of claim 1 , wherein the first and second conduits ( 922 , 923 ) are fluidly connected to the first conduit element ( 56 ) by a common line ( 928 ).

4. The resuscitation bag system ( 1 ) of claim 1 , wherein the first flow restrictor ( 924 ) comprises a first calibrated orifice for limiting the gas flow to the first flowrate.

5. The resuscitation bag system ( 1 ) of claim 1 , wherein the second flow restrictor ( 925 ) comprises a second calibrated orifice for limiting the gas flow to the second flowrate.

6. The resuscitation bag system ( 1 ) of claim 2 , wherein the monitoring module ( 70 ) comprises an electronic board ( 701 ) comprising a control unit ( 702 ) for processing data ( 701 , 702 ).

7. The resuscitation bag system ( 1 ) of claim 2 , wherein the monitoring module ( 70 ) further comprises a light emitter/receiver ( 705 , 706 ).

8. The resuscitation bag system ( 1 ) of claim 2 , further comprising:

a valve element ( 50 ) arranged in the main conduit ( 5 ) and comprising a venting port ( 62 a ), and

a main one-way valve ( 53 ) arranged in the main conduit ( 5 ), between the hollow flexible bag ( 54 ) and the valve element ( 50 ).

9. The resuscitation bag system ( 1 ) of claim 8 , further comprising a derivation line ( 49 ) fluidly connected to the main conduit ( 5 ), between the hollow flexible bag ( 54 ) and the main one-way valve ( 53 ), and further to the valve element ( 50 ), the derivation line ( 49 ) adapted for controlling the opening or closing of said valve element ( 50 ).

10. The resuscitation bag system ( 1 ) of claim 4 , wherein the first calibrated orifice is configured for limiting the gas flow to the first flowrate of greater than 10 L/min.

11. The resuscitation bag system ( 1 ) of claim 5 , wherein the second calibrated orifice is configured for limiting the gas flow to the second flowrate of less than 2 L/min.

12. The resuscitation bag system ( 1 ) of claim 8 , wherein the monitoring module ( 70 ) is fixed to the valve element ( 50 ).

13. The resuscitation bag system ( 1 ) of claim 6 , wherein the control unit ( 702 ) comprises a microcontroller.

14. A gas delivery assembly ( 1 , 2 ) comprising:

the resuscitation bag system ( 1 ) according to claim 8 , and

a source of oxygen ( 2 ) fluidly connected to the first valve ( 92 ) of the resuscitation bag system ( 1 ) via an oxygen line ( 21 ).
