Problems solved by technology

[0005] However, one disadvantage of this method is that some liquid may drain from the nozzle and accumulate at the nozzle outlet
Such inappropriate functionality of the drug inhaler may result in inaccurate drug delivery, high risk of device failure, etc.

Embodiment Construction

[0050] The following detailed description illustrates embodiments of the disclosure and how they can be practiced. Although certain modes of carrying out the disclosure have been disclosed, those skilled in the art will recognize that other embodiments for carrying out or practicing the disclosure are also possible.

[0051] In one aspect, embodiments of the present disclosure provide a portable inhaler having a rotary actuation mechanism movable sequentially and alternately between a primed position and an actuated position and comprising:

[0052] - a driven assembly releasable to dispense the medicament when the rotary actuator moves from the priming position to the next priming position and capable of priming when the rotary actuator moves from the actuating position to the next priming position;

[0053] - a rotary loading device comprising a cam assembly and a cage assembly, wherein the cam assembly is surrounded by the cage assembly and engages therewith by interfering ...

Abstract

Disclosed is a portable inhaler, having a rotary actuation mechanism, and comprising a follower component (104), a rotary loading device (106) and a button (112). The rotary loading device comprises a cam component (108) engaged with a cage component (110), to allow a predetermined limited rotational relative movement therebetween. The button is translatable between a central position and an extended position, and can be engaged by the cam component upon rotary movement of the rotary actuation mechanism to its primed position to translate the button to its extended position, and the button can engage the cam component to effect rotary movement of the rotary actuation mechanism to its actuated position as the button translates to its central position thereby releasing the follower component.

Description

technical field [0001] The present disclosure relates generally to medical devices, and in particular to medicament inhalers; and more particularly to loading and drive mechanisms for medicament inhalers. Background technique [0002] Drug inhalers have long been used to deliver drugs for the treatment of lung, respiratory and other related diseases. Drug inhalers are capable of dispensing small volumes of fluid (such as pharmaceutical compounds, drugs, etc.) at a flow rate of microliters / milliliters per minute. The fabrication of such drug inhalers is of particular interest as a robust method of fluid delivery in many important applications such as controlled and accurate drug delivery. Typically, the way in which practical drug inhalers work is to load and trigger a metered dose of drug through a narrow outlet such as a nozzle. [0003] Most inhaler devices are designed to be loaded prior to use and then actuated using a simple low force button. This low-force operation...
