ABSTRACT:
A spacer for delivering a medication spray from an inhaler includes a first conical body joined to a second conical body, forming a continuous spray conduit through first and second internal chambers of the respective first and second conical bodies. A mouthpiece is formed in the proximal end of the first conical body. A spray inlet for attachment to the inhaler is formed at the distal end of the second conical body. A plurality of air inlets are placed downstream of the medication inlet proximate to, or in, the large diameter distal end surface of the first conical body. Recirculation zones are created in the first and second chambers, to force the medication spray into a central airflow path through the spray conduit, minimizing particle deposition by contract with the walls of the spacer.
