Protective cover for a medical ventilator that can be used in a contaminated environment of the NRBC type
The invention relates to a protective cover ( 1 ) for a medical ventilator ( 20 ) adapted for use in a contaminated environment, in particular an NRBC environment, having a peripheral casing ( 2 ) defining an internal compartment ( 3 ) designed to accommodate a medical ventilator ( 20 ). The peripheral casing ( 2 ) has a plurality of connection interfaces ( 4, 5, 6, 7 ) sealably attached to said peripheral casing ( 2 ). Each connection interface ( 4, 5, 6, 7 ) has at least one internal gas passage with at least one gas inlet and at least one gas outlet. A sealing device is arranged in the internal gas passage of at least one connection interface ( 4, 5, 6, 7 ) for sealing said internal gas passage.
1. A protective cover ( 1 ) for a medical ventilator ( 20 ) adapted for use in a contaminated environment, comprising a peripheral casing ( 2 ) defining an internal compartment ( 3 ) designed to accommodate a medical ventilator ( 20 ), wherein:
the peripheral casing ( 2 ) comprises a plurality of connection interfaces ( 4 , 5 , 6 , 7 ) sealably attached to said peripheral casing ( 2 ), comprising:
a first connection interface ( 4 ) allowing fluid connection of a patient circuit ( 21 ); and
a second connection interface ( 5 ) allowing fluid connection of an air purification device ( 11 );
and each connection interface ( 4 , 5 , 6 , 7 ) comprises at least one internal gas passage ( 14 ) with at least one gas inlet ( 15 ) and at least one gas outlet ( 16 );
characterized in that at least one sealing device ( 18 ) is arranged in the at least one internal gas passage ( 14 ) of at least one connection interface ( 4 , 5 , 6 , 7 ) for sealing said at least one internal gas passage ( 14 ).
2. The protective cover according to claim 1 , characterized in that at least one sealing device ( 18 ) is arranged in the at least one internal gas passage ( 14 ) of each connection interface ( 4 , 5 , 6 , 7 ).
3. The protective cover according to claim 2 , characterized in that at least one sealing device ( 18 ) is a non-return valve.
4. The protective cover according to claim 1 , characterized in that at least one portion of the peripheral casing ( 2 ) is formed by at least one transparent polymer material.
5. The protective cover according to claim 1 , further comprising:
a third connection interface ( 6 ) allowing fluid connection of a Positive Expiratory Pressure (PEP) pressure control line ( 12 ); and/or
a fourth connection interface ( 7 ) allowing fluid connection of an oxygen supply line.
6. A ventilation assembly ( 1 , 20 ) that can be used in a contaminated environment, comprising a medical ventilator ( 20 ), around which a protective cover ( 1 ) according to claim 5 is sealably arranged.
7. The ventilation assembly according to claim 6 , characterized in that the protective cover ( 1 ) comprises the peripheral casing ( 2 ) comprising the first ( 4 ), the second ( 5 ) and the fourth ( 7 ) connection interface, wherein:
the first connection interface ( 4 ) comprises a gas inlet ( 15 ) fluidly connected to a gas outlet ( 24 ) of the medical ventilator ( 20 );
the second connection interface ( 5 ) comprises a free gas outlet ( 16 ) leading into the internal compartment ( 3 ) of the casing ( 2 ); and/or
the fourth connection interface ( 7 ) comprises an oxygen outlet ( 16 ) fluidly connected to an oxygen inlet ( 25 ) of the medical ventilator ( 20 ).
8. The ventilation assembly according to one of claim 7 , characterized in that:
the first connection interface ( 4 ) is fluidly connected to a patient circuit ( 21 );
the second connection interface ( 5 ) is fluidly connected to an air purification device ( 11 ); and/or
the fourth connection interface ( 7 ) is fluidly connected to an oxygen supply line.
9. A ventilation system ( 1 , 20 , 21 ) comprising:
the ventilation assembly according to claim 6 , comprising a medical ventilator ( 20 ), around which a protective cover ( 1 ) is arranged;
a patient circuit ( 21 ) comprising a flexible gas hose ( 22 ) provided with a breathing interface ( 23 ), said flexible gas hose ( 22 ) being fluidly connected to the first connection interface ( 4 ) of the protective cover ( 1 ); and
an oxygen supply line supplied with oxygen by an oxygen container fluidly connected to the fourth connection interface ( 7 ) of the protective cover ( 1 ).
10. The protective cover as claimed in claim 1 , characterized in that the plurality of connection interfaces ( 4 , 5 , 6 , 7 ) are formed by at least one semi-rigid material.
