Abstract:
An inhalation device includes: a chamber for intermediate storage of an aerosol, a first connection for a nebuliser that produces the aerosol, a second connection on a patient side for delivering the aerosol, and a third connection for breathable air, where the chamber is fluidically connected in a valve-free manner on an inlet side to the first connection when the nebuliser is attached, and the chamber is connected to the third connection in parallel on the inlet side via an inlet valve so that the breathable air from the third connection flows into the chamber.
Abstract:
A nebulizer includes an insertable container and a securing mechanism for holding the container in the nebulizer such that the container can move back and forth but cannot be separated. The securing mechanism is formed by a metal unitary part. The securing mechanism forms a transportation lock for holding the container unmovable in the housing in a delivery state of the nebulizer. The securing mechanism forms a cage which encompasses the container.
Abstract:
The invention relates to a dispenser (1) for pasty substances (11), consisting of a tubular substance housing (2) having a follower plunger (7) and a hand-actuatable headpiece (3) which is equipped with a mouthpiece and is linearly guided for dispensing the substance and can be depressed in the direction of the follower plunger (7) while tensioning a return spring element (25) that structures itself by buckling. In order to provide a dispenser for pasty substances that, in particular, has improved function of the return spring element compared with the prior art and can be produced in a cost-effective manner, it is proposed that the middle portion (29) of the resilient return spring element (25) folds up into the portioning chamber (18) of the headpiece (3), the return spring element (25) transitioning from a curved S-shape into the shape of two oppositely oriented U-portions (33, 33′), and the two end portions (28, 30) being clamped at the headpiece (3) and at an upper tube part (9) of the substance housing (2).
Abstract:
An inhaler including a pre-inserted cartridge (100) is proposed. The cartridge contains liquid (103) which is preferably pressurized to a low pressure. The cartridge is connected via an aerosol valve (106) with the inhaler. The liquid is further pressurized by a pump (117) of the inhaler to a high pressure and atomized.
Abstract:
The sprayer of the present invention has a conventional first lever and a second lever with continuous teeth along an edge. When the first lever is engaged, the second lever drives a rotatable piece inside a gravity wheel. Two blocks at the ends of the rotatable piece, as the rotatable piece turns, press some ratchets inside the gravity wheel to turn the gravity wheel. The gravity wheel in turn drives a gear set connected to an energy storage element such as a winding spring. The gear set further engages an eccentric gear with a shaft attached to it so. As the energy storage element is wound and unwound, the shaft is put into continuous back-and-forth movement to work on a pump of the sprayer. As such, a number of sprays are produced continuously.
Abstract:
A fluid dispenser for dispensing a metered volume of a fluid product having a storage chamber for storing the fluid product in; a dispensing outlet through which the fluid product is dispensable from the dispenser; a metering chamber which is adapted to provide the metered volume of the fluid product for dispensing through the dispensing outlet by movement of the metering chamber between a contracted state and an expanded state, movement of the metering chamber from the contracted state to the expanded state placing the metering and storage chambers in fluid communication to enable the metering chamber to receive from the storage chamber an excess volume of the fluid product comprising the metered volume and a surplus volume; and a bleed arrangement adapted to bleed the surplus volume of the fluid product from the metering chamber is described.
Abstract:
An apparatus to make a certain volume of liquid available for atomization comprises a container adapted to hold a liquid, and a piston pump. The piston pump comprises a piston member and a valve body, with the piston member being slidable within the valve body. Further, the valve body functions with the piston member to define a metering chamber. In this way, the metering chamber is adapted to be filled with liquid from the container when the piston member is moved to a filling position, and the piston pump is adapted to dispense a known volume of the liquid from the metering chamber when the piston member is moved to a dispensing position.

Abstract:
A miniaturized device for pressurizing fluid. The device includes a hollow piston that provides a fluid path and a valve member. The valve member is configured for axial movement so that the valve axis remains parallel to the piston axis. The valve member is arranged at one end of the hollow piston. The valve member may be partially or completely disposed within the hollow piston. The device is particularly adapted for use in a mechanically operated atomizer to produce an inhalable aerosol of a liquid medicament without the use of propellant gas.
