Abstract: A method for evaluating the pump actuation for a pump dispenser that includes two sub-units which can be moved manually towards one another and a pump which has a pump chamber that can be made smaller by moving the sub-units from a first end position into an actuated second end position. The force with which the sub-units are moved towards one another is detected by a force sensor during movement of the sub-units. The curve over time of the detected force is evaluated such that an increase in force is identified which is characteristic for reaching the actuated second end position. Depending on whether the increase in force was detected, a signal which is characteristic for the result is haptically, acoustically and/or visually output and/or transmitted via a wireless interface to an external display apparatus, by means of an output device.

Abstract: An inhalation device including a housing, which encloses a liquid reservoir in which the liquid is stored before discharge, and an applicator head with a nebulization chamber and an applicator piece connected thereto, wherein the applicator piece is designed either as a mouthpiece, to be received in the mouth of a patient, or as an inhalation mask, to sealingly cover the mouth, the nose, or the mouth and the nose. The inhalation device furthermore has a discharge channel which connects the liquid reservoir to the applicator head. The inhalation device includes at the end of the discharge channel a nozzle plate with a large number of nozzle openings which serve to generate an inhalation mist and through which the liquid from the liquid reservoir is conveyed into the nebulization chamber.

Abstract: A discharge head for a liquid dispenser having a coupling device fastening to an outlet connector of a liquid store, a liquid inlet, and a discharge opening. The discharge head has a pump device conveying liquid from the liquid inlet to the discharge opening, and a ventilation channel. The discharge head has an end surface by which the liquid store is substantially closed off at the distal end of the outlet connector and which is extended through by the liquid inlet. The end surface and the coupling device are formed as part of a common main component. The end surface has a ventilation aperture which is part of the ventilation channel and through which air flows into the liquid store in an inflow direction. The ventilation aperture has a minimum clear cross section of at most 3·10?2 mm2.

Abstract: A dispenser includes a housing and a discharge opening provided at the distal end of the housing. The dispenser includes a liquid reservoir and a control device having a pump or a switching valve, which control device is connected by a first line to the liquid reservoir and by a second line to the discharge opening, and via which control device liquid is conducted from the liquid reservoir to the discharge opening. The dispenser includes a push button provided laterally in a cutout of a circumferential face of the housing and connected to the control device such that pressing the push button actuates the control device so that liquid is conducted to the discharge opening. Measures for securing the dispenser include a rotatable sleeve over the push button, a secured cap, a securing arrangement on the push button, an interaction of the push button with an opposite side of the dispenser, and a receiving sleeve for the dispenser.
