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.

Inhalation actuated device for use with metered dose inhalers (MDIs)

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 user's 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.

Inhalation actuated device for use with metered dose inhalers (MDIS)

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 a flow inhibiting mechanism connected to a blocking plate positioned to selectively block fluid flow between the secondary and primary inhalation passage. As the user's 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.

Dry powder medicament inhalator having an inhalation-activated flow

An inhalation device is provided for use with pressurized metered dose inhalers (MDIs). The device includes a mechanical mechanism for applying the force required to discharge the MDI, a breath-activated trigger for activating this mechanical mechanism, an auto-return mechanism for insuring recovery of the aerosol canister from the fired position and a dose counter for counting the doses dispensed or available. Arming of the device is achieved by removing the protective mouthpiece cover/dust cap. Activation of the MDI is set to occur at a point subsequent to the beginning of inhalation.

Device for use with metered dose inhalers (MDIS)

An inhalation-activated inhalator having a flow diverting means wherein the primary air flow channel is blocked for a brief period during inspiration with air flow during that period passing through a dosing chamber arrangement and connecting passage to inject medicament into the inspired air stream is provided. By diverting the inspired air stream in this fashion, powdered medicament may be provided for inhalation at a particular point in the patient's inspiration cycle, thereby optimizing the delivery of medicament to the lungs.

A breath-actuated dry powder medicament inhalator device having a housing and a conduit mounted within the housing defining an air passageway therethrough having an aperture in the sidewall thereof. A blister-type strip of sealed containers arranged in a matrix of rows and columns wherein the columns extend generally diagonally to the longitudinal axis of the strip is secured in a two-piece cage adapted for being rotatably mounted around the conduit of the inhalator device. Advancement means are provided for rotatably moving the two-piece cage and blister strip contained thereby in a generally helical pathway relative to the conduit so as to successively advance each of the sealed containers of the blister strip into registration with the conduit aperture. Piercing means are associated with the housing for successively piercing each of the sealed containers of the blister strip when advanced into registration with the conduit aperture by the advancement means in order to introduce the dry powder compound contained therein into the air passageway of the conduit.
