Device for administering insulin in controlled dosages by controlling total inhaled volume

摘要

Dosages of inhaled insulin are controlled within a narrow range by controlling the total volume of air inhaled by a patient. By repeatedly delivering aerosolized insulin with the same total inhaled volume of air, the amount of insulin delivered to the patient each time is consistent. A device (40) comprises a means (11, 29) for measuring inhaled volume and for halting inhalation at a predetermined point. The device also comprises an adjustable means (9) for applying various amounts of force to a container (1) of formulation (5) to expel different amounts of drugs from the container based on the force applied.
