Embodiment Construction

[0100] Such as figure 1 and figure 2 As shown, the inhaler 1 00 has a reusable assembly 109 and the reiled assembly 110.

[0101] The inhaler 100 (or a portion thereof, such as a reusable assembly 109 and / or re-filled assembly 110) has a longitudinal axis A which defines an axial direction extends along the axis or substantially parallel to the axis. By moving the reproducible assembly 110 and the reusable assembly 109 in the axial direction (e.g., along the axis A) toward each other toward each other, the reusable assembly 109 is coupled together.

[0102]The inhaler 100 has an air inlet (or suction hole) 101, the display screen 151, and the display screen cover 102, the control button 103, the patient port cover (eg, a portable member cover) 104, the actuator assembly 105, the air sealing cap 106, The rear outer casing 107 and the front outer housing 108. In the way, the air inlet 101, the display cover 102, the control button 103, the rear outer casing 107, and the front oute...

Abstract

The present invention provides a refill assembly for use in a medicinal inhaler, the refill assembly being configured as a reusable assembly removably coupled to the medicinal inhaler, the refill assembly comprising: a patient port; a canister , the canister is actuatable by the reusable assembly to deliver a dose of drug to the patient port; the cannula, the cannula is selectively actuatable by the user independently of the reusable assembly to act on the canister To deliver a dose of drug, the sleeve has a first position in which the sleeve cannot be actuated to release the dose of drug from the canister and a second position in which the sleeve can actuate to move a dose of drug to the patient port; the refill assembly also includes an override element engaging the sleeve, the override element being movable from a first position to a second position in which the first position , the cannula is held by the override element in its first position, in which second position the cannula is allowed to move to its second position when depressed by the user.

Description

[0001] Cross-reference related application [0002] The Rights of the British Patent Application GB1706504.6 submitted on April 25, 2017, the entire disclosure of which is incorporated herein by reference. Technical field [0003] The entire disclosure relates to a medical inhaler including a lock over-control mechanism, and specifically, but non-exclusive, it involves a medicinal inhaler including such a reusable assembly and a reusable component. Background technique [0004] Conventional use of a pressurized metering inhaler (PMDI), a dry powder inhaler (DPI) or an atomizer type of inhaler to deliver atomized drugs to the respiratory tract for treatment of breathing and other diseases. In particular, the PMDI inhaler has become industry standards and is familiar for many patients with asthma or chronic obstructive pulmonary disease (COPD). Conventional PMDI devices include aluminum cans, which are sealed with a metering valve and accommodate the pharmaceutical preparation. Typ...
