ABSTRACT:
A mask adaptor ring for connecting a medication inhaler having an extended cylindrical breathing tube to masks with attachment connections of child and adult size, the mask adaptor comprising a compound annular ring with a central opening, the central opening having an inlet end and an outlet end, the inlet end having an inside diameter slightly larger than the outer diameter of a child mask attachment, the outside diameter of the outlet end having a diameter slightly smaller than inner diameter of the adult mask attachment, and the inlet end having an outside diameter slightly smaller than the outlet end opening of the extended breathing tube. A skirting is provided for size adaptability to outlet end openings of various cylindrical breathing tubes. The invention also has a center flange disposed between its inlet end and its outlet end, the flange having a diameter larger than the outer diameter of the adult mask attachment and of the outlet end opening of the extended breathing tube. The inlet end and the outlet end of the mask adaptor ring are tapered so that they are at their smallest at the top and bottom of the mask adaptor ring. The taper is at an angle of 1.degree.-4.degree. and tapers outward from the top and bottom toward the center flange. The central opening at the outlet end is tapered inward at an angle of 1.degree.-4.degree. toward the center flange. The tapers allow for slight variations in mask attachment and extended cylindrical tube sizes.
