Patent number: 10092714Abstract: The present disclosure relates to a dose indicator for a pressure-actuated metered dose inhaler (pMDI) device. In an embodiment, the dose indicator comprises a chassis element having a viewing portion, a display element located within the chassis element, a resilient deformable element, and an indexing element having an axis, translation of the indexing element along its axis from a first position to a second position causing deformation of the resilient deformable element in the same direction as translation of the indexing element resulting in generally greater displacement of portions of the resilient deformable element nearer to the axis relative to portions thereof further from the axis, the displacement of the portions of the resilient deformable element in the same direction as translation of the indexing element inducing indexing of the display element from a current position to a subsequent position relative to the viewing portion of the chassis element.Type: GrantFiled: August 29, 2013Date of Patent: October 9, 2018Assignee: 3M Innovative Properties CompanyInventors: Adam J Stuart, Peter D Hodson

Publication number: 20160136365Abstract: 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.Type: ApplicationFiled: July 8, 2014Publication date: May 19, 2016Inventors: ADAM J STUART, STEPHEN J HOWGILL

Publication number: 20160121060Abstract: An actuator for an inhaler, in particular a nasal actuator, is disclosed, the actuator comprising a body, a stem post and fixing means for fixing the stem post in the body. The body comprises a delivery passage for delivery of a medicament and a canister opening for insertion of a canister having a metering valve with a valve stem. The stem post comprises a stem socket for receiving the valve stem of a canister and comprises an orifice for discharging a medicament to the delivery passage. The stem post and body are adapted so they cooperate to define a transition chamber when the stem post is fixed in the body. Also disclosed is a method of forming an component for an actuator for an inhaler, and a method of assembling an actuator for an inhaler by inserting the stem post through the canister opening and into the body thereby.Type: ApplicationFiled: May 12, 2014Publication date: May 5, 2016Applicant: 3M Innovative Properties CompanyInventors: Richard D. Brewer, Adam J. Stuart, Neale F. Griffiths

Patent number: 9089661Abstract: A dose counter for use in connection with a device adapted for metered dispensing of a medication is described. 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.Type: GrantFiled: July 2, 2013Date of Patent: July 28, 2015Assignee: 3M INNOVATIVE PROPERTIES COMPANYInventors: Adam J. Stuart, Graham R. Purkins, Rachel V. Striebig, Stephen J. Howgill, Peter D. Hodson, Richard D. Brewer, Benjamin J. Holden

Publication number: 20150136122Abstract: 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.Type: ApplicationFiled: June 13, 2013Publication date: May 21, 2015Inventors: Adam J. Stuart, Peter D. Hodson, Stephen J. Howgill, Matthew A. Oakley, David J. Greenleaf
