The present disclosure provides a universal breathing tube adaptor that can accept or otherwise accommodate a metered dose canister (MDC) having a variety of shapes, structures, sizes, and/or configurations. The present breathing tube adaptor includes a sidewall which defines a chamber. A conduit extends from the chamber through a floor of the device for discharging aerosolized medicament from the MDC. The sidewall includes opposing exposed edges which define a channel. The sidewall supports the MDC when it is invertingly inserted into the chamber. The channel permits structure of an MDC to extend radially outward through the channel and outside the chamber thereby enabling the valve stem of the MDC to engage the conduit.

1. A device for delivering a medicament into a breathing tube comprising: a counter metered-dose canister (CoMDC) comprising a container having medicament disposed therein, a valve stem and a housing attached to the top of the container surrounding at least a portion of the valve stem, the housing having a counter window, the CoMDC having a maximum cross-sectional diameter between the counter window and an opposing side of the housing; and,a substantially cylindrical body comprising a top rim, a floor, and an arcuate sidewall extending therebetween, the floor extending radially inward from the sidewall, the body defining a chamber having a diameter less than the CoMDC maximum diameter, the chamber receiving the inverted CoMDC;a vertical conduit extending from the chamber interior through and below the floor, the conduit comprising an upper portion extending above the floor and into the chamber interior, the upper portion having a well located above the floor and within the chamber interior and adapted to engage the valve stem, and the conduit comprising a lower portion having a discharge port disposed below the floor for dispensing medicament;the arcuate sidewall comprising opposing exposed edges defining a U-shaped profile free of the sidewall, the U-shaped profile extending from the top rim substantially to the floor, the U-shaped profile forming a channel adapted to guide longitudinal movement of the counter window through the channel as the valve stem moves into engagement with the conduit well, when the inverted CoMDC is inserted into the chamber, the counter window extends between the opposed exposed edges and extends radially outward beyond the diameter of the chamber; anda breathing tube connector connected to the breathing tube that is adapted to be connected to an intubated patient, the breathing tube connector comprising an inlet in fluid communication with the discharge port for receiving medicament dispensed from the CoMDC;wherein the device excludes a boot-type inhaler. 2. The device of claim 1 wherein the channel provides a single load configuration for the inverted CoMDC. 3. The device of claim 1 comprising a counter actuator extending upwardly from the floor for actuating a counter of the CoMDC when medicament is dispensed. 4. The device of claim 1 wherein the valve stem is reciprocally engaged with the conduit well. 5. The device of claim 1 wherein the inlet comprises a Luer port. 6. The device of claim 1 wherein at least a portion of the counter window extends radially outward through the channel and outside the chamber. 7. The device of claim 1 wherein the conduit lower portion tapers as it extends distally from the bottom of the floor. 8. The device of claim 1 wherein the conduit lower portion comprises a lower passageway that narrows to a distal spray section at the discharge port. 9. The device of claim 1 wherein the opening in the sidewall has a distance from 10 mm to 18 mm between the exposed edges. 10. The device of claim 1 wherein the conduit lower portion directs aerosol spray into the interior of the breathing tube connector and avoids collection of the spray on the breathing tube connector interior surfaces. 11. A method for administering aerosolized medicament to an intubated patient, the method comprising: providing a counter metered-dose canister (CoMDC) comprising a container having medicament disposed therein, a valve stem and a housing attached to the top of the container surrounding at least a portion of the valve stem, the housing having a counter window, the CoMDC having a maximum cross-sectional diameter between the counter window and an opposing side of the housing;invertingly inserting the CoMDC into a device that excludes a boot-type inhaler comprising, a substantially cylindrical body comprising a top rim, a floor, and an arcuate sidewall extending therebetween, the floor extending radially inward from the sidewall, the body defining a chamber having a diameter, the chamber adapted to receive the inverted CoMDC, a vertical conduit extending from the chamber through and below the floor, the conduit comprising an upper portion extending above the floor, the upper portion having a well located within the chamber interior for engaging a valve stem of the CoMDC, and a discharge port disposed below the floor for dispensing medicament, and the arcuate sidewall comprises opposing exposed edges defining a U-shaped profile free of the sidewall, the U-shaped profile extending from the top rim substantially to the floor, the U-shaped profile between the opposing exposed edges forming a channel;placing the discharge port in fluid communication with an inlet of a breathing tube;reciprocally engaging the valve stem with the conduit well;guiding, with the opposing exposed edges, the counter window along the channel as the valve stem moves into engagement with the conduit well and placing the counter window between the opposed exposed edges to extend the counter window radially outward beyond the diameter of the chamber; anddownwardly dispensing aerosolized medicament from the CoMDC through the conduit into the breathing tube. 12. The method of claim 11 comprising longitudinally moving the CoMDC into the chamber. 13. The method of claim 11 comprising dispensing, vertically downward, the aerosolized medicament from the CoMDC through the conduit into the breathing tube.
