Metered dose atomizer

摘要

An atomizer has a venturi nozzle positioned at an outlet end of an air line and has a discharge end and is oriented horizontally when in use and forms a mixing chamber at its discharge end. A valve is positioned at a canister port and actuable to allow a metered flow of gas at a predetermined pressure and time through the air line and venturi nozzle. A suction line extends from the venturi nozzle and mixing chamber to a medication receiver and draws medication upward and mixes it with gas passing through the venturi nozzle into the mixing chamber and atomizes the medication into a mist.

主权项

1. An atomizer, comprising:
a atomizer body comprising an air channel section and atomizer outlet; an air line extending through the air channel section and having an inlet and an outlet, including a flared extension at the outlet; a venturi nozzle at the outlet end of the air line and having a discharge end and oriented horizontally when in use; a canister port at the inlet end of the air line that receives a gas canister, and a valve positioned at the canister port and actuable to allow a metered flow of gas at a predetermined pressure and time to flow from the gas canister and through the air line and venturi nozzle; a medication receiver carried by the atomizer body proximal to the venturi nozzle and configured to receive and lock in position a medication container, the medication container including knob extensions to lock it into position; and a suction line having a proximal and distal end, and the proximal end connected to the discharge end of the venturi nozzle and having a tapered bore and extending from the venturi nozzle to the medication receiver and configured to connect at its distal end into the medication container locked in position at the medication receiver, wherein the proximal end of the suction line includes a diffuser configured with the suction line and venturi nozzle as a mixing chamber, wherein gas that is mixed with medication in the mixing chamber impacts the diffuser to aid in forming a mist, wherein the venturi nozzle, suction line and diffuser are connected as an integral one-piece replaceable unit, wherein the venturi nozzle outputs air in a direction that is normal to the suction line.
