Embodiment Construction

[0016] image 3 The hand-held device 1 shown in the schematic sectional view in , is used for dispensing sprayable substances, in particular inhaled medicaments.

[0017] For this purpose, the handheld device 1 firstly has a handheld device housing 2 into which a magazine 3 containing the sprayable substance can be inserted. The storage box 3 can move axially in the casing 2 . The magazine head 4 has, in a conventional manner, a central ventilation duct 5 extending coaxially with the magazine 3 . The medicine is output through the ventilation conduit through the axial relative movement between the storage box 3 and the housing 2 . The suction device housing 2 is divided into two halves and consists of two ring parts 6 and 7 placed one above the other, wherein the upper ring part 6 is shaped like a shaft and the lower ring part 7 has a shape approximately transverse to the direction of extension of the shaft. Oriented mouthpiece 8. The mouthpiece element can be closed by a ...

Abstract

The invention relates to a step-by-step mechanism, particularly for hand-held devices (1) for the portioned delivery of medicaments to be inhaled, comprising a graduated collar (26), which can be moved during an actuation stroke and which encircles the center axis of the housing (34). In order to provide a step-by-step mechanism of the aforementioned type with a more reliable operation while, in aspatially advantageous manner, having a simplified design, the invention provides that the switching finger(s) (S, 28) are permitted to slope upward from a hub (29) located in the center.

Description

technical field [0001] The invention relates to a step switch device, in particular to a step switch device used in a hand-held device for outputting inhaled medicine in proportion. Background technique [0002] Such step switching devices, for example designed according to GB-PS1317315, are used in particular for medical aerosol therapy for the treatment of respiratory diseases. A cartridge held under pressure within the housing contains the medicament to be inhaled. In order for the drug to flow out, the magazine needs to be moved axially within the device. The device, which usually consists almost entirely of the cartridge, generally also has a mouthpiece and / or an adapter for inhalation through the nose. It is necessary to provide the user with a counting device by means of which the amount of drug used or still present in the magazine is displayed. Since a specific amount of medicament is released each time the magazine is actuated, it is known to link the counting d...
