摘要:
A discharge device for discharging pharmaceutical liquids, with a housing, a liquid reservoir with a receiving space for storing the pharmaceutical liquid, and a discharge opening which is provided on the housing and which connects the receiving space to an environment and serves to dispense the pharmaceutical liquid. A pretensioned spring mechanism is provided, by means of which liquid in the receiving space of the liquid reservoir is subjected to pressure and which, in the assembled state of the discharge device, is not accessible for input of energy.

A dosing device with a manually actuated pumping component, which includes a pumping chamber, an inlet valve and an outlet valve in the region of a dosing opening, is provided. An inlet region in the region of the inlet valve and/or an outlet region in the region of the outlet valve is/are provided with flow profiles. The dosing device is to be used for dispensing pharmaceutical liquids.
摘要:
A discharging device for pharmaceutical liquids having an actuator for carrying out a discharging operation of a pharmaceutical liquid. A first subordinate unit of the actuator has a discharge orifice, and a second subordinate unit is displaceable relative to the first subordinate unit for carrying out the discharging operation. The two subordinate units together delimit a buffer chamber from which a liquid passageway leads to the discharge orifice. A liquid-containing bag is accommodated in the buffer chamber and has film-like walls. The actuator and the bag are coordinated such that displacement of the subordinate units of the actuator relative to each other causes opening of the bag and reduction in the volume of the buffer chamber with consequent volume reduction of the liquid-containing bag and discharge of liquid through the discharge orifice.

According to the invention a dispenser for discharging media, particularly liquids, foams and pastes is proposed and whose dispenser casing is secured against dismantling. This is implemented by means of a securing section (16b, 144), which is engaged on the pump casing separately from a functional section (20, 116) axially displaceable in operation on the dispenser casing and which is connected by positive or frictional engagement with the functional section (20, 116) and in the joined state limits a first locking profiling (22, 122) provided on the functional section (20, 116) with regards to its elastic resilience, so that a second locking profiling (26, 126) provided on the pump casing and corresponding with the locking profiling (22, 122) of the functional section (20, 116) can no longer be overcome for dismantling purposes. The invention also relates to a method for the assembly of disassembly-secured dispensers, in which an auxiliary section and an applicator are successively engaged on a pump casing, are joined together in the engaged state and in the engaged state are secured against dismantling.
摘要:
In a dispenser, particularly an atomizer, which is used for flowable substances, particularly pharmaceuticals, use is made of a pump, which must be actuated one or more times for priming purposes. Its discharge nozzle (14) is covered by a protective cap (38), which is suitable to collect and store the medium, which is discharged during the priming strokes and before the start of the useful strokes. During the priming strokes the protective cap (38) is secured on the dispenser (11). This is brought about in that a locking (40) for the protective cap is only released when the priming strokes have been performed. This can take place by electrical actuation or by material change under the influence of the medium to be discharged. According to a variant the protective cap is not itself locked, but an actuation locking takes place if the protective cap has not been fitted for the priming strokes.

The invention relates to an apparatus for the atomized discharge of a liquid medium. The apparatus can be operated with one hand for the discharge of a liquid medium in partial strokes that are successively performed and not unintentionally interrupted. The apparatus has an operating trigger to engage the ram, which operates the piston that is displaceable in the spray cylinder, the operating path of the operating trigger being so limited between an operating starting position and end position that the resulting discharge stroke of the piston may vary for successive partial discharges of the stored medium.
摘要:
Discharging unit for discharging pharmaceutical media from a medium storage receptacle, including a first discharge orifice, a pump, an inlet duct connecting the medium storage receptacle to the pump, and an outlet duct for connecting the pump to the first discharge orifice. The first discharge orifice is part of a first subordinate device of the discharging unit and the pump, a portion of the outlet duct, and an outlet valve provided in the outlet duct are part of a second subordinate device of the discharging unit. The first subordinate device is capable, without the use of tools, of being coupled to, and decoupled from, the second subordinate device, and an internal volume of a portion of the outlet duct extending from the outlet valve to the first discharge orifice is less than 15 μl.
摘要:
An actuating device for a manually operable medium dispenser includes an energy store for storing an actuating energy necessary to actuate the medium dispenser and a control device for liberating the actuating energy. The control device is being configured for a liberation of the actuating energy when a minimum energy stored in the energy store is exceeded.
摘要:
A discharge device for media includes an outer housing with a discharge opening, a discharge handle for manual actuation. A support is arranged in the outer housing. Movable along a main axis relative to the outer housing and connected to the discharge handle, it has a seat for a pump dispenser. A pump is actuated by compression of the pump dispenser. A first abutment on the housing interacts with the pump dispenser, actuating the pump.The support has a functional portion which acts on the pump dispenser with a force oriented in the direction of the first abutment on the housing. An adjuster is provided between the handle and the functional portion of the support, by which the position of the functional portion relative to the first abutment on the housing can be adjusted for a defined setting of the discharge handle.
