Abstract:
1. An adaptor for delivering an aerosolized medicament to a patient with concurrent ventilation comprising: a chamber defining an interior space and having a patient interface output port and a ventilator gas input port, said ventilator gas input port defining a first cross-sectional area, wherein said patient interface output port communicates with said interior space at a first location and said ventilator gas input port communicates with said interior space at a second location positioned upstream from said first location, wherein a downstream flow direction is defined from said ventilator gas input port to said patient interface output port and wherein said ventilator gas input port and said patient interface output port define non-parallel axes, wherein said interior space defines a second cross-sectional area transverse to said downstream flow, wherein said second cross-sectional area is greater than said first cross-sectional area; and an aerosol flow channel having an inlet port separate from said ventilator gas input port and an outlet port disposed in said interior space of said chamber at a third location positioned upstream from said first location and downstream from said second location, and wherein said outlet port opens and discharges into said interior space in said downstream flow direction away from said ventilator gas input port and toward said patient interface output port, wherein said downstream flow direction does not cross said outlet port in a perpendicular relationship, wherein a ventilator gas flow path between said ventilator gas input port and said patient interface output port at least partially encircles said aerosol flow channel and wherein said aerosol flow channel is defined at least in part by a curved wall extending into said interior space of said chamber.
