摘要:
A powder inhaler for administering powder by inhalation, comprising: a flow path defined by a plurality of surfaces through which a stream of air is in use drawn on inhalation by a user; and dosing means (18) for providing a dose of powder to the flow path for entertainment in the stream of air; characterized in that the inhaler further comprises dislodging means for dislodging powder accumulated on a surface of the flow path downstream of the dosing means (18).
摘要:
The present invention relates to a gas-liquid mixture especially for use as a fire extinguishing agent. The mixture contains a) at least one halogenated carbon or C1-C10 hydrocarbon, b) a chemical compound having a high steam pressure and a low boiling point, high solubility in the halogenated compound and a capacity of dispersing the halogenated compound, and/or an inert gas. The invention also relates to a fire extinguishing unit and a method for using the mixture.
摘要:
A system for dispensing a clinically effective dose of an inhalable, pharmaceutically active compound, which system includes a dry powder inhaler device containing a powder containing the pharmaceutically active compound, wherein(a) of the powder particles dispensed by the inhaler device (the "metered DPI dose"), at least 40% are less than about 10 microns in diameter at the point the particles exit the inhaler,(b) the metered DPI dose is sufficient to produce a clinically effective result in a patient; and(c) the amount of the compound in the metered DPI dose is not more than 70% of the minimal amount of the compound which, when dispensed in a pressurized metered dose inhaler, produces an equivalent clinically effective result in the same patient.

The mixture containsa) at least one halogenated carbon or C.sub.1 -C.sub.10 hydrocarbon,b) a chemical compound having a high stream pressure and a low boiling point, high solubility in the halogenated compound and a capacity of dispersing the halogenated compound, and/or an inert gas.The invention also relates to a fire extinguishing unit and a method for using the mixture.
摘要:
A method is provided for dispensing a clinically effective dose of an inhalable, pharmaceutically active compound. The method includes providing a dry powder inhaler containing a powder including the pharmaceutically active compound, and administering to a patient a dose of the compound that is less than 70% of the dose that would be necessary to obtain a physiologically equivalent result were the compound administered by a pressurized metered dose inhaler. The pharmaceutically active compound is in the form of primary particles at least 80% of which have a particle size of less than 10 microns, and the primary particles are provided as agglomerates which are deagglomerated during inhalation so that at least 40% of the dose administered is in the form of primary particles.
摘要:
An apparatus for treating a package container blank with a fluid is disclosed and includes a rotary portion provided with a plurality of chambers for receiving the blanks and a fixed portion having a stator surface that faces the rotary portion. The fixed portion is provided with an arrangement that opens to the stator surface for supplying fluid so that upon successive rotations of the rotary member, the chambers will successively align with the arrangement for supplying fluid so that fluid is thereby supplied to the chambers.
摘要:
A thermoforming apparatus for forming a blank into a composite article. The thermoforming apparatus includes a forming tool. A forming member forms the blank over the forming tool. A first chamber is arranged for containing the blank. A second chamber is separated from the first chamber by the forming member. A first air circulator is configured to circulate air in the first chamber for achieving a heat distribution to the blank. The first air circulator includes a controllable valve member. The apparatus also includes a second air circulator. A method for forming a blank during circulation of air in a first chamber.
