Dispensers, in particular dispensers for dispensing a dose of a gaseous, gas borne or droplet substance from a substance source and dispensers containing dosage counters are described herein.

A counting device for distance measuring wheel includes a housing, a transmission assembly, a counter wheel assembly, and a reset control assembly. An elastic support unit of the reset control assembly is arranged at the side of each of the transmission assembly and the counter wheel assembly so that the relative positions among the transmission assembly, the counter wheel assembly, and the reset control assembly arranged inside the housing are changed and the size of the counter wheel assembly may become larger while the size of the housing is not changed.

Provided herein are new devices for indicating the status of events, such as the number of relevant events that are remaining and/or that have already occurred up to the present moment and to related devices, systems, and methods. In some aspects, the event-related indicator devices of the invention are used within larger dispensing devices or systems, e.g., to provide the status of administration of a substance contained therein (e.g., a drug). In an exemplary embodiment, the indicator devices find particular utility within medicament dispensers, such as metered dose inhalers, to provide a visual indication of the status of doses having been or remaining to be administered.

A device has a latching mechanism including a catch element having at least two catches, and a pawl configured to engage in a catch interstice between two catches. The catch element is movable in relation to the pawl in a freewheeling direction, and a movement of the catch element in relation to the pawl in a blocking direction may be blocked by means of the pawl. The device further includes a deflectable actuator configured to move the catch element and the pawl relative to each other on a catch-by-catch basis in the freewheeling direction by means of deflection. According to the invention, the device also includes an electric component configured to change its electric property as a function of the catch-wise movement of the catch element in relation to the pawl.

A handheld device for dispensing a pharmaceutical substance has a housing in which a storage container with the pharmaceutical substance and a counter are arranged. The storage container dispenses the pharmaceutical substance by pressure actuation by a user after a specified displacement path has been traversed, and the counter carries out an action in order to rotate a counter wheel of the counter on the basis of the displacement path being traversed. The counter additionally has a drive part rotates the counter wheel, and the counter wheel is rotatably attached to a mounting part. The mounting part is formed independently of the housing, and the drive part is directly attached to the mounting part. The handheld device advantageously dispenses a pharmaceutical substance in that the action is first carried out on the counter wheel of the counter upon the pressure actuation, and the pharmaceutical substance is then dispensed.

Some embodiments of a tally stamp device described herein provide a stamp and a counter system. The tally stamp may include an elongate body housing the stamp and counter system.

A fluid dispenser comprising a body (1), a fluid reservoir (2), a dispenser member, such as a pump or a valve, mounted on said reservoir (2), and a dose indicator device for indicating the number of doses of fluid that have been dispensed or that remain to be dispensed from said reservoir, the dispenser being characterized in that said dose indicator device includes a first safety system for actuating the dose indicator device once the dispenser has performed a predetermined incomplete actuation stroke, even if the dispenser does not perform the complete actuation stroke.

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
