The invention relates to a counter for coupling to a measuring mechanism of a fluid meter, wherein an output of measuring mechanism gear is in operative engagement with a gear on the side of the counter, the gear on the counter being designed to adapt to the rotational direction of the measuring mechanism by means of a change wheel. The invention also relates to a counter, which can be connected to a modular base plate system via a mechanical interface, wherein the base plates of this system can be designed having differently arranged detent or engagement elements.

An activation mechanism for an aerosol dispenser is presented having a first housing structure, an actuation member movably arranged in the first housing structure, wherein the first housing structure is provided with an actuation member opening in level with the axial position of the actuation member, and an activation member slidably attached to the first housing structure, the activation member slides between a non-triggering position and a triggering position relative to the first housing structure, wherein the activation member has a radially flexible tab portion that is offset from the actuation member opening when the activation member is in the non-triggering position, restricting radial flexing of the tab portion, and wherein the tab portion aligns with the actuation member opening when the activation member is in the triggering position, thereby enabling the tab portion to flex radially inwards to cause movement of the actuation member.

A dose counting mechanism for an aerosol dispenser is presented where the dose counting mechanism has a first body structure, a second body structure rotatably attached to the first body structure, an annular dose counter provided with a plurality of teeth along its perimeter, the dose counter being arranged coaxially with the first body structure and the second body structure, each of the first body structure and the second body structure being rotatable relative to the dose counter, a rotatable actuator that meshes with the teeth of the dose counter, the actuator being configured to follow the perimeter of the dose counter when the second body structure is rotated relative to the first body structure, and a rotator that rotates concurrently with one of the first body structure and the second body structure and that engages with the actuator when rotation of the first body structure relative to the second body structure is initiated.

There is provided a dose counter assembly for use with a medicament dispenser, the dose counter assembly comprising: a) a units dose display means comprising a first count indicia and one or more driver teeth; b) a tens dose display means comprising a second count indicia; and c) a driver, wherein the first count indicia and second count indicia align at a common viewing area to collectively display a count sequence.

The finger-mounted mechanical counter is a numerical counter that may be worn on the finger of a user. First, second and third wheels each have a set of indicia formed thereon, each set of indicia being a circumferentially arrayed set of integers, such as a continuous range from 0 to 9. The first, second and third wheels are rotatably mounted within a housing having corresponding first, second and third slots formed therein for display of the corresponding indicia. The housing defines a central passage which is adapted for receiving the finger of the user. After a full rotation of the first wheel, the second wheel is rotated by a single increment, and after full rotation of the second wheel, the third wheel is rotated by a single increment, allowing for consecutive counting from single digits to double digits to triple digits.

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.

A nebulizer for nebulizing a liquid from a container includes a fluid pump for withdrawing the liquid in doses from the container and pressurizing the respective doses for nebulization. The nebulizer includes in addition an air pump with a piston/cylinder arrangement for pumping air into the container to pressurize the liquid in the container to help withdrawing the liquid from the container.

The present disclosure relates to a dose indicator comprising, a chassis comprising a chassis frame and a displacement portion, an indexable first display unit, mountable on the chassis, the first display unit being indexable about a first display axis, the indexable first display unit comprising a plurality of indexing teeth, a first display non-return arm, and a drive pawl connected at its proximal part to the displacement portion, the drive pawl comprising a socket at its distal part, the socket being adapted to engage an indexing tooth of the first display unit during indexing. The disclosure further relates to an actuator for an inhaler, wherein the actuator comprises a dose indicator as described above. The present disclosure is also directed to an inhaler comprising such actuator.

A counter for a handheld device for dispensing a pharmaceutical substance includes at least one counter wheel having legible characters. The counter wheel is rotatable about a rotational axis, and a drive part having a shaped engagement section rotates the counter wheel. An acting part, displaceable relative to the counter wheel in the direction of extension of the rotational axis against a spring force, is connected to and rotates together with the drive part. A base part which can form a part of the housing and can be inserted into the housing at least partly overlaps the substance container in the direction of the longitudinal axis of the substance container, and has a stationary rotational axis for the counter wheel, the drive part preferably being guided in the rotational axis. The drive part is located on the side of the substance container with respect to the counter wheel.

An activation mechanism for an aerosol dispenser is presented having a first housing structure, an actuation member movably arranged in the first housing structure, wherein the first housing structure is provided with an actuation member opening in level with the axial position of the actuation member, and an activation member slidably attached to the first housing structure, the activation member slides between a non-triggering position and a triggering position relative to the first housing structure, wherein the activation member has a radially flexible tab portion that is offset from the actuation member opening when the activation member is in the non-triggering position, restricting radial flexing of the tab portion, and wherein the tab portion aligns with the actuation member opening when the activation member is in the triggering position, thereby enabling the tab portion to flex radially inwards to cause movement of the actuation member.
