Publication number: 20250108180Abstract: A dry powder inhaler includes a powder storage element configured to hold a powdered medicament and an inlet channel receives powdered medicament from the powder storage element that is entrained in an airflow. The inlet channel has a first diameter and defines an opening. The inhaler includes a dispersion chamber that receives the airflow and the powdered medicament from the opening. The dispersion chamber has a second diameter. The inhaler includes an actuator housed within the dispersion chamber. The actuator oscillates within the dispersion chamber when exposed to the airflow to deaggregate the powdered medicament entrained by the airflow passing through the dispersion chamber. A ratio between the first diameter and the second diameter is between about 0.40 and 0.60 such that an audible sound is produced as the actuator oscillates. The inhaler includes an outlet channel through which the airflow and powdered medicament exit the inhaler.Type: ApplicationFiled: December 12, 2024Publication date: April 3, 2025Applicant: Respira Therapeutics, Inc.Inventors: Robert M.
