摘要:
The invention relates to pharmaceutical active substances, active substance mixtures and formulations for use as an aerosol in propellant-containing [1.1.1.2-tetrafluoroethane (HFC-134a) or 1.1.1.2.3.3.3-heptafluoropropane(HFC-227)] metered-dose aerosols and the metered-dose aerosols for administering these active substances, active substance mixtures and formulations.
摘要:
A dispensing device, a storage device and a method for dispensing a medical formulation are proposed. Multiple doses of the formulation are stored in a carrier having multiple inserts, each insert containing a single dose. Preferably, each insert has at least one duct or nozzle for dispensing the respective dose. Each insert is located in a separate and sealed cavity in the carrier. The cavities can be individually opened for dispensing the respective dose from the respective insert.
摘要:
A dispensing device, and a method for dispensing powder in which powder is dispensed through a duct with a flat cross section to de-agglomerate the powder and to generate a spray with fine particle size. A storage chamber for the powder may be closed by a bursting element which is burst by pressurized gas for discharging the powder, the gas pressure reaching or exceeding a peak value before the bursting element bursts so that the powder is dispensed at a lower gas pressure. The powder may be forced through the duct by a gas pressure of less than 300 kPa to de-agglomerate the powder and/or to generate the spray. The storage device can have multiple storage chambers and associated ducts or nozzles, so that each dose of powder can be dispensed through a separate duct or nozzle, the storage chamber and duct or nozzle being formed of a one-piece construction.
摘要:
A discharge device and a method for evaporating a liquid to the atmosphere are proposed. The liquid pressurized by gas is supplied to an evaporator via a flow restriction device which restricts the flow rate of the liquid such that continuous release and evaporation of the liquid is possible. Further, an evaporator is proposed. The evaporator comprises an evaporation surface which is designed preferably by microstructuring such that the surface area is increased and/or the liquid forms an essentially uniform film on the evaporation surface.
摘要:
A dispensing device dispenses a liquid, in particular containing or formed of a drug, as a fine spray, that has a high fraction of small particles achieved by using a duct or slit having a flat cross section. Additionally or alternatively, the nozzle or duct has at least one sharp change in cross section and/or alternate sections with large and small cross-sectional areas.

A finger operated spray pump has a liquid reservoir (1), a cylinder (3) for containing a portion of the liquid from the reservoir (1) which is connected at one end to an atomizer (5), a piston (6) sealingly mounted within the cylinder (3) and movable within the cylinder (3) in a spray stroke, a passageway (7) connecting the cylinder (3) with the liquid reservoir (1), a one way valve (8) at the passageway (7) for allowing a flow of liquid only from the supply of liquid (2) into the cylinder (3), and a finger operated actuator (9) which is displaceable relative to the liquid reservoir (1). The outer diameter of the piston (6) and the corresponding inner diameter of the cylinder (3) is between about 0.5 mm and about 4.0 mm, the nozzle diameter of the atomizer (5) is between 15 μm and 150 μm, the operating pressure within the cylinder (3) during the spray stroke with average finger force is between 10 bar and 400 bar and the atomizer (5), the cylinder (3), the piston (6) and the one way valve means (8) are designed to withstand the operating pressure.

A nebulizer is proposed which comprises a replaceable container containing fluid, a housing part detachable from the nebulizer for replacing the container, and an operation counter inseparable from the housing part as depicted in exemplary FIG. 10. The operation counter comprises a lead screw and an associated rider both supported by the housing part.
摘要:
A spray head for an aerosol tank, and an aerosol tank having a spray head is provided, which includes a fluid exit valve for spraying a low-solvent fluid. The fluid exit valve of the aerosol tank defines an axial fluid exit direction. The spray head includes a capillary tube for routing the fluid and for nozzle-less spraying of the fluid. An entry end of the capillary tube is axially joined to the fluid exit valve when the spray head has been seated on the aerosol tank. An exit end of the capillary tube is open to the ambient atmosphere. In the spray head, the capillary tube runs from the entry end to the exit end in an arc of approximately 90°.
摘要:
A dispensing device has a storage device and an air pump for dispensing a medical formulation. The storage device has multiple inserts, each insert containing a single dose of the formulation. Each insert is located in a separate and sealed cavity. The cavities can be individually opened for dispensing the respective dose from the respective insert by a connecting element that is moveable relative to the inserts for individually supplying air from a air pump to a respective one of the receptacles. A manually operated actuator is radially moveable to operate the air pump and to rotate the storage device to the next receptacle, and/or radially move the connecting element to individually open the respective receptacle, and to connect the pump to the respective receptacle and/or to push an insert out of the respective receptacle.
