20080202515 | Inhalation Device - An inhalation device ( | 08-28-2008 |
20090173346 | DOSE COUNTER - This application discloses a dose counter for use in connection with a device adapted for metered dispensing of a medication. The dose counter has a first count indicator that has a first indicia bearing surface, with the first count indicator being rotatable about a first axis. The dose counter also has a second count indicator that has a second indicia bearing surface, with the second count indicator being rotatable about a second axis. The second axis is disposed at an obtuse angle with respect to the first axis, and the first and second indicia bearing surfaces align at a common viewing area to collectively present at least a portion of a medication dosage count. | 07-09-2009 |
20100229855 | DOSE COUNTER - A dose counting device for use with a medicinal metered dose dispensing device, the device comprising an actuator having at least one finger that is designed for reciprocal movement comprising an outward stroke and a return stroke, an annular member having a helical thread segment formed about a circumferential arc on a part of its surface, and a drive nut positioned around a radial cross-section of the annular member and having an internal helical rib engaged with said helical thread segment on the annular member whereby rotation of the drive nut about the circumferential arc of the annular member results in rotational movement of the annular member, the outer surface of the drive nut comprising one or more driving surfaces for engagement by said at least one finger on the actuator during said reciprocal movement to cause rotation of the drive nut. | 09-16-2010 |
20110042419 | METERED DOSE VALVE - An aerosol metering valve comprising: (a) a valve stem movable between a rest position and a firing position comprising: a body portion comprising a circumferential sealing surface (b) a valve body comprising: a body wall, and an internal chamber defined at least in part by the body wall; and (c) a metering gasket having an inner periphery defining an aperture, being disposed near the most interior end of the internal chamber and being configured to be able to form a transient, substantially fluid-tight face seal against the circumferential sealing surface of the valve stem, where at the rest position of the valve stem, the body portion of the valve stem is located within the internal chamber and as the valve stem is moved from its rest position towards its firing position the circumferential sealing surface of the valve stem contacts the metering gasket to form a face seal thereby closing a metering chamber and thereafter further movement of the valve stem towards its firing position causes the metering gasket to deflect while maintaining the seal with the circumferential sealing surface of the valve stem; and wherein the metering gasket in an unbiased configuration is an annular disc having a substantially planar form and where the valve is constructed and arranged such that the inner periphery of the metering gasket is urged out of said substantially planar form at the rest position of the valve stem, or wherein the metering gasket is pre-biased into a dished-shape. | 02-24-2011 |
20150136122 | Metered Dose Dispensing Valve - The present disclosure relates to a metered dose dispensing valve for dispensing metered volumes of an aerosol formulation from an aerosol container. The valves described herein are particularly suitable for use with metered dose inhalers for the oral delivery of medicaments. By combining the compliant biasing member and the second valve body into an integral single component it is possible to provide a desirable metered dose dispensing valve for use in inhalation devices or for use in the provision of canisters targeted for use in inhalation devices. | 05-21-2015 |
20160136365 | Dose Indicator or Dose Counter - 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. | 05-19-2016 |
