摘要：
A dose counter for counting the doses of medication supplied by or remaining is a metered dose inhaler, the dose counter comprising: a rotating wheel gear wheel (130) having a circular arrangement of ratchet teeth (132) that define a root circle； an indicator coupled to the gear wheel (130), the indicator having a visible series of dose counting indicators that can be indexed in response to the rotational movement of the gear wheel (130)； and an actuator mechanism (118) having an impeller (124) for rotationally pushing the gear wheel (130) in response to the supply of a dose of medication, the impeller (124) being arranged to engage the ratchet teeth ( 132) of the gear wheel (130), in which the actuator mechanism (118) comprises an actuator shaft mounted for linear movement in response to the supply of a dose of medication and an interaction arm (122) carrying the impeller (124), the actuator axis (120) and the interaction arm (122) being configured such that, during use of the dose counter to count a delivered dose, the impeller displacement (124) along the root circle (134) of the gear wheel (130) exceeds the corresponding linear displacement of the actuator shaft, characterized in that the interaction arm (122) is pivotally mounted on the actuator shaft (120).Un contador de dosis para contar las dosis de medicamento suministradas por o restantes es un inhalador de dosis medida, comprendiendo el contador de dosis: una rueda de engranaje (130) montada de manera giratoria que tiene una disposición circular de dientes de trinquete (132) que definen un círculo raíz； un indicador acoplado a la rueda de engranajes (130), teniendo el indicador una serie visible de indicadores de contaje de dosis que se pueden indexar en respuesta al movimiento giratorio de la rueda de engranajes (130)； y un mecanismo actuador (118) que tiene un impulsor (124) para empujar de manera giratoria la rueda de engranaje (130) en respuesta al suministro de una dosis de medicamento, estando el im
