1. A medication dosage inhaler system for allowing a patient to safely and efficiently deliver a predetermined medication dosage comprising, in combination:

  • a cylindrical main body fabricated of rigid plastic material having an inward portion and an outward portion with an inner surface and an outer surface with a radial edge there between, the outward portion having a round hollow cylindrical configuration with a first inside diameter and a first outside diameter and a wall thickness there between with the outward wall of the outward portion having an inward end and an outward end with a length there between, the outward end of the outward portion having a plurality of apertures there through with each of the apertures having one of a plurality of internal diameters, the inward portion having a round hollow cylindrical configuration with a second inside diameter, sized to receive and securely hold the first outside diameter of the outward portion and a second outside diameter and a wall thickness there between with the inward portion having an inward end and an outward end, with the inward portion having a radially extending cylindrical hollow medication passageway located at the approximate midpoint between the inward end and the outward end with the passageway extending in an upward direction and perpendicular to the primary axis of the main body, the passageway having a round inner surface and a round outer surface and a wall thickness there between, with the inward portion of the main body being coupled to the outward portion of the main body at the outward end of the inward portion and the inward end of the outward portion;

    a T-shaped adaptor fabricated of rigid plastic material and having round cylindrical hollow configuration with a second inside diameter and a second outside diameter and a wall thickness there between with the adaptor having a radially extending stepped gas connector located at the approximate midpoint of the adaptor, the connector forming an open pathway through the wall of the adaptor for the deliverance of a medical gas, the adaptor can be rotatable so that the passage of gas can be opened or sealed with respect to alignment with an aperture in the main body;

    an end cap fabricated of rigid material and having a round hollow cylindrical configuration with a second inner diameter and a second outer diameter with a wall thickness there between with the end cap having an inward end and an outward end and a length disposed there between with the outward end including a one way valve with a plurality of cross members, a central point of attachment and a flexible flapper one way valve membrane located within the inner diameter to provide for a one way flow of gas through the end cap and the inward end having a plurality of apertures with each of the apertures having one of a plurality of diameters with the end cap apertures being located to be overlying the outward portion apertures of the main body when the end cap is coupled with the main body and when in position the end cap being rotatable for adjustment of air flow through the apertures, and thus controlling inhalation resistance;

    a medication dosage delivery container having a generally round delivery mouth and a round slightly tapered container portion with the delivery mouth having a projecting medication delivering tube which, when positioned in the working configuration within the passageway of the inward portion lies in a radial axis to the primary axis at the approximate center of the primary axis of the inward portion;

    a mouthpiece fabricated of rigid material having an outward portion and an inward portion, the outward portion having a round cylindrical tubular configuration with a first inner diameter and a first outer diameter and sized to be coupled with the inner portion of the main body, with the inner portion of the mouthpiece having a generally arcuate configuration to conform to the user'"'"'s grip within the user'"'"'s mouth; and

    an oxygen source having a female adaptor configured to be received by and mate with the stepped gas connector of the T-shaped adaptor.
