A pharmaceutical dispenser with a housing, a medium reservoir, a discharge opening, connection channel connecting the medium reservoir to the discharge opening, and a detection device arranged in the area of the connection channel and designed to detect medium flowing therein. The connection channel is connected to and communicates with a pressure chamber, the detection device includes a membrane which delimits the pressure chamber, and includes an electrically conductive connection portion and is subjected to pressure. The detection device has an electrical mating contact surface in relation to which a membrane-side connection portion is movable when subjected to pressure, such that an electrical contact between the conductive connection portion and the mating contact surface is established or cancelled.

Pharmaceutical dispenser with a detection device

A dispenser for dispensing a pharmaceutical medium, including a sensor for sensing a dispensing operation and an electronic processing circuit for sensing and further processing a signal caused by the sensor. In order to simplify the design, the sensor is part of a sensor unit, which has a radio transmitter for producing a radio signal, and the processing circuit has a radio receiver designed to receive the radio signal produced by the radio transmitter.

Dispenser having electronic actuation detection

A discharging apparatus having two housing portions displaceable in relation to one another, a discharging opening for discharging a medium, and a reservoir for storing the medium. A manual displacement movement of the housing portions causes medium to be delivered from the reservoir to the discharging opening. The discharging apparatus has an electric load, an electromagnetic generator by which the mechanical energy introduced upon actuation is converted into electrical energy for supplying the electric load, and the electromagnetic generator has a magnet and a conductor connected to the electric load. A spring energy store with a stressing member movable in relation to the second housing portion, and a spring acting between the second housing portion and the stressing member are provided.

Discharging apparatus for media

A microdosing device with a dosing chamber for the at least temporary reception of a liquid quantity, and with which is associated at least one discharge opening is provided. A vibrating unit in operative connection with at least one boundary surface of the dosing chamber is provided in order to vibrate the same for a discharge process, and with a delivery function unit connected to the vibrating unit for activating the latter during a delivery time period. A drying function unit is additionally provided and can be activated in time-separated manner with respect to the delivery function unit in order to free the dosing chamber from liquid residues.

Microdosing device

A discharge device for media has a housing (), an operating member () manually movable relative to the housing () and which, for performing a discharge can be transferred from an unoperated starting position in the direction of an operating direction () into an operated end position and with a locking member (), which is displaceable relative to the housing () between a locked position where it prevents the displacement of the operating member () into the end position and a release position in which it permits the displacement of the operating member () into the end position.

Discharge device

A metering device for dispensing a medium to an environment is provided. The metering device includes a housing, a shallow metering chamber within the housing which is of planar design and is essentially closed off from the environment by wall sections, a first media inlet which is connected to the metering chamber and can be connected to a media reservoir, and a vibration mechanism which is arranged in such a manner that vibrations generated by the vibration mechanism cause pulsing changes in volume of an internal volume of the metering chamber. A wall section which is designed as an outlet wall section has metering openings so that the metering chamber is connected to the environment. The vibration mechanism forms a vibration wall section so that the metering chamber is delimited.

Metering device

A dosing device with an electromechanical interface is provided. The dosing device includes delivery means, a medium reservoir and an applicator, on the one hand, and a control unit and electrical energy store, on the other hand, in separate structural units. Guide means are provided for fitting one of the structural units into the other structural unit. The guide means has an electromechanical interface for coupling and/or uncoupling relative to the control unit and/or energy store without using tools.

Dosing device

A metering device with an applicator housing having an application orifice for medium discharge. A metering pump conveys medium from a medium store to the applicator. An electronic counting module having a stroke detection means operatively engageable with a relatively movable pump portion of the metering pump. A data processing processor evaluates signals from the stroke detection means, and an indicator unit indicates data produced by the data processing processor. A current source supplies the data processing processor with current. A module housing houses an electronic counting module. The external dimensions of the module housing are conformed to the internal dimensions of a reception space. The reception space is open on one side of the applicator housing, so that the module housing can be inserted completely into the reception space through the opening and be fastened therein.

Metering device for a medium

A microdosing device includes a dosing chamber which at least temporarily receives a quantity of liquid, and to which at least one dispensing opening is assigned. A vibration unit is operatively connected to at least one boundary surface of the dosing chamber in order to cause this boundary surface to oscillate for the purpose of a dispensing operation. At least two admission channels spaced apart from one another are provided on the dosing chamber.
