US Patent:

6357442, Mar 19, 2002

Filed:

Oct 27, 1998

Appl. No.:

09/181150

Inventors:

Robert A. Casper - Raleigh NC
Frank A. Leith - Chapel Hill NC
David L. Gardner - Chapel Hill NC
John Medlin Snow - Raleigh NC
Zachary Wood Lyon - Raleigh NC

Assignee:

Innovative Devices, LLC - Raleigh NC

International Classification:

A61M 1100

US Classification:

12870023, 12820014, 12820312, 12820315, 12820323

Abstract:

A device for use with metered dose inhalers includes a housing configured with a void to receive a metered dose inhaler, an actuator assembly which is configured to selectively apply force to the metered dose inhaler to cause the metered dose inhaler to release medicament, and a cocking mechanism for placing the actuator assembly in an armed configuration. The device is configured to actuate the metered dose inhaler as the user inhales, thereby ensuring improved medicament delivery. Additionally, the device is configured to prevent the metered dose inhaler from remaining in a vented position.

International Classification:

A61M 1600

US Classification:

12820321, 12820315, 604 58

Abstract:

An inhalation-activated inhalator having a primary inhalation passage and a secondary inhalation passage disposed in communication with the primary inhalation passage and a source of medicament. The primary inhalation passage has airflow inhibiting mechanism connected to a blocking plate positioned to selectively block fluid flow in the secondary inhalation passage. As the users inhalation reaches a defined rate, the flow inhibiting mechanism restricts flow through the primary inhalation passage and moves the blocking plate to enable airflow through the secondary passage. Thus, as the user achieves a desired inhalation rate, the medicament is provided through the secondary inhalation passage, thereby optimizing the delivery of medicament to the lungs.

Abstract:

A medicament respiratory delivery device including a housing having a chamber including coaxially aligned inlet and outlet, a medicament cartridge located within the chamber having a passage therethrough and membranes sealing the passage having a burst pressure of less than 10 atmospheres, a manually actuatable fluid delivery device having an outlet in fluid communication with the chamber and a manually actuated valve located between the outlet of the fluid delivery device and the chamber inlet for delivery of fluid under pressure to the valve. The medicament respiratory delivery device of this invention may be utilized to deliver a controlled unit dose of an aerosolizable medicament on demand by first pressurizing a pressure chamber in the pressure delivery device upstream of the valve, then opening the valve to open the membranes and express the medicament through the chamber outlet.
