Embodiment Construction

[0060] The present invention relates to a two-component (with optional third component) dose indicator for pMDIs. When the patient actuates the pMDI valve, the resulting displacement can index the indicator.

[0061] exist Figure 1 to Figure 7 In the embodiment shown, the dose counter 1 comprises a dose-by-dose counter for pMDI (which can be configured to count down from 200 to 0) comprising a base 2, a ones display unit 33 and an optional tens display Unit 42. The dose counter 1 can be plugged into a standard pMDI actuator.

[0062] Such as figure 1 with Figure 7 As shown, the dose counter 1 comprises a base 2 having a base frame 4 of generally annular shape. The annular shape of the base frame 4 is designed to fit snugly in the inhaler actuator to provide support and prevent deformation in use. Optionally, this support may be reinforced by one or more flanges on the actuator to seat the horizontal surface of the base, or ribs / grooves to prevent deformation and relat...

Abstract

A dose indicator or dose counter is disclosed which includes an indexable first display unit indexable about a first display axis, an indexable second display unit indexable about a second display axis, the second display axis being transverse to the first display axis, and a chassis comprising a chassis frame, a displacement portion comprising a drive means to engage the first display unit, and at least one hinge means directly or indirectly connecting the displacement portion and chassis frame. The drive means is preferably configured to index the dose indicator. The dose indicator / counter has a small number of components yet is effective, reliable and compact.

Description

[0001] Cross References to Related Applications [0002] This patent application claims priority from UK Patent Application 1312448.2, filed 11 July 2013, which is hereby incorporated by reference in its entirety. Background technique [0003] The present description relates to dose indicators or counters, and more particularly to dose indicators or counters for pressurized metered dose inhaler (pMDI) devices. The invention also relates to an actuator comprising such a dose indicator / counter and an inhaler comprising such an actuator. [0004] Patients using inhalers such as pMDI devices need to monitor the use of their inhalers, and drug regulators have begun requiring some means of dose indication to be included in inhalers. Dose counters (providing an accurate count of the number of doses remaining) and dose indicators (providing an indication of the number of doses remaining) for inhalers are well known. [0005] In most dose counters and dose indicators, the display wi...
