An add-on holding chamber for an inhaler mixer system has a holding chamber, mouthpiece, and attachment interface is coupled to the mouth inlet of the prior art inhaler, to provide a better mixing efficiency. The chemical from the medicament canister is sprayed into the air inlet side of the prior art inhaler, which enters the holding chamber, and as the user sucks onto the mouthpiece of the add-on holding chamber, air flows into the holding chamber (via inlets in the holding chamber which operate to move more air and/or vortex additional air) towards the air inlet side of the prior art inhaler. The added inhaled air provides more air and force to aerosolize with more efficiency the chemical/air mixture in the holding chamber. |

1. An oral inhaler holding chamber mixing device, comprising:
a sealed holding chamber with three openings: an external air inlet opening, an interface opening, and a mouthpiece opening; and a holding chamber-to-inhaler interface coupled to the interface opening of the holding chamber, the interface comprising:
a channel disposed through the interface, adapted to provide a pathway between a top and bottom of the interface;a sealing portion, adapted to match the holding chamber's interface opening, sealing the holding chamber's interface opening but for the channel; andan attachment feature disposed on an upper portion of the interface, adapted to enable removable attachment of an inhaler mouthpiece to the interface and align a mouthpiece of an inhaler with the channel,
wherein the mixing device aerosols a chemical from an attached inhaler with external air drawn through the inlet opening in the holding chamber, which is inhaled through the holding chamber's mouthpiece opening. |
