Abstract:
The present invention relates to a dose counter for counting the number of doses of fluid that have been dispensed or that remain to be dispensed from a fluid dispenser device, said counter comprising a cylindrical housing (2), a trigger member (1), a ratchet member (3) and a counter member (4) constructed and arranged to undergo a predetermined counting movement each time a dose is dispensed.
Abstract:
An assembly for a counter mechanism (5) for a drug delivery device (1 ) is described comprising a drive member (12), wherein the drive member (12) is adapted and arranged to be rotated in a first rotational direction and to be prevented from rotation in a second rotational direction which direction is opposite to the first rotational direction, an advancing member (1 1 ) adapted and arranged to be axially moved and rotated with respect to the drive member (12), wherein the advancing member (1 1 ) is adapted and arranged to mechanically cooperate with the drive member (12) such that the drive member (12) is rotated in the first rotational direction, and a display member (13) which is configured to count a number of doses and to display the counted number of doses, wherein the assembly is adapted and arranged such that rotation of the drive member (12) in the first rotational direction is converted into a counting movement of the display member (13). Furthermore, a drug delivery device (1 ) comprising the assembly is described.
Abstract:
A counter (7) for a rising plate meter (1), the counter (7) comprising a counter body integrally formed with a tubular upstand (3) adapted to, in use, slideably receive a ground engageable probe rod (2) of a rising platemeter (1), the counter (7) including actuation means (9a, 9b) to, in use, generates measurement of the position of the ground engaging end (5) of the said probe rod (2) relative to the underside of a plate (4) of the said platemeter (1), and a display means (8), the counter (7) being characterised in that the display means (8) is oriented at an angle of between 90° and 30° from the longitudinal axis of the tubular upstand (3).
Abstract:
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.
Abstract:
Improved counter device (1) having a hollow casing (2) on the inside of which a mechanical type of numerator assembly (3) is housed with an activation device for the numerator assembly (3), and wherein said activation device has a rod (4) that is axially moveable in a straight line having a protrusion that is perpendicular to the rod (4) coupled in a elongated hole (7) located in a moving element (6) jointed in a fixed point that can move at an angle; said moveable element (6) being coupled at one end to a toothed wheel (8) connected to the hub of the numerator assembly (3) itself, in a such way that when the rod (4) moves, when receives a impulsion, to record a numeric count brought about by the slide of the protrusion along the mentioned elongated hole (7) in turn bringing about the angular sliding of the moveable element (6) that activates the toothed wheel of the assembly (3).
Abstract:
This invention is a usage indicator member (260) disposed in a housing (200), the usage indicator member (260) comprising usage indicia visible to the user which indicates the number of usage cycles completed by or remaining for the indicating device. The indicating member (260) is rotatable mounted in the housing (200) for rotational movement transverse to, in response to axial movement between a cap (220), and a base member (50) of the housing (200).
Abstract:
The invention relates to an inhalator for discharging an aerosol comprising a dosage counting device (11). The dosage counting device comprises a first (12) and a second (13) counting ring and has a coupling device (24, 25, 26, 27) located between the counting rings.
Abstract:
Various embodiments of the present invention provide dosage counters, such as those useful in dispensers or containers. Suitable dispensers or containers include spray pump containers, metered dose inhalers and the like. Counters may include at least one indicia, including, but not limited to, numbers, colors, markings or words such as days that indicate the number or amount of dosages that have been used or remain in the device.
Abstract:
The present invention relates to a metered dose inhaler dose counter, the counter comprising: an actuator; a rotary gear wheel having a plurality of ratchet teeth; a driver for driving the rotary gear in a step-wise fashion in response to displacement of the actuator; a pawl that prevents reverse rotation of the rotary gear; and a display coupled to the rotary gear.
Abstract:
The invention relates to a dose indicator (A) which is intended for a fluid product dispensing device (B). The inventive indicator consists of at least one rotary counting means (10) which can move in rotation and which comprises indicator means (15), said indicator means indicating the number of doses that have been distributed or that remain to be distributed. Moreover, said at least one counting means is actuated by an actuation member (35) which is in turn actuated by a transmission element (34) that is designed to co-operate with the dispensing device each time the latter is actuated. The dose indicator comprises amplification means which are designed to amplify the movement of the transmission element (34) with each actuation, such that the movement of the actuation member (35) is greater than the movement of the transmission element (34).
