摘要:
A dispensing device (1) for dispensing powder (2) as a spray (3) is disclosed. The dispensing device comprises a duct (5) through which the powder is dispensible by gas pressure for de-agglomerating the powder. The duct is angled by at least about 90 degrees at a diversion portion (12) and/or diverted into two opposite directions at a fork portion (15) so that the powder is impacted on to a solid surface (14) for powder de-agglomeration.
摘要:
A dispensing device (1) having a storage device (4) and an air pump (18) for dispensing a medical formulation is proposed. The storage device (4) comprises multiple inserts (6), each insert (6) containing a single dose of the formulation (2). Each insert (6) is located in a separate and sealed cavity (7). The cavities (7) can be individually opened for dispensing the respective dose from the respective insert (6).

摘要:
An aqueous or powder composition includes anti-gram-negative antibiotic or salt thereof being present at an amount ranging from about 100 mg/ml to about 200 mg/ml. Another aqueous or powder composition includes anti-gram-positive antibiotic or salt thereof being present at a concentration ranging from about 0.6 to about 0.9 of the water solubility limit, at 25° C. and 1.0 atmosphere, of the anti-gram-positive antibiotic or salt thereof. Other embodiments include unit doses, kits, and methods.
摘要:
A focused droplet nebulizer (104) of the invention produces substantially uniform droplets (210) of a predetermined size. Droplets (210) are pushed out through a small outlet orifice (306) by the contraction of a chamber. The droplets (210) can b'e carried on a substantially non-divergent path in a drift tube (108). A piezo-controlled membrane micro pump (202) acts in response to an electrical control signal to force a droplet out of the outlet orifice (306). The nebulizer can operate at frequencies permitting a stream of individual droplets (210) of the predetermined size to be sent along the substantially non-divergent path in the drift tube (108) in a preferred embodiment ELSD device.
摘要:
An aerosol generating device generates an aerosol having a desired particle size by passing a liquid through a flow passage heated to convert the liquid into a vapor. The flow passage includes an outlet section that controls the exit velocity of the vapor and produces an aerosol with a desired particle size. The aerosol generator can be incorporated in a hand held inhaler, and the liquid can include a medicament, which is delivered to a targeted portion of the lung using the inhaler.
摘要:
A storage device (4) and a dispensing device (1) are proposed. The powder (2) is dispensed through a duct (5) with a flat cross section to de-agglomerate the powder and to generate a spray (3) with fine particle size. A storage chamber (10) for the powder may be closed by a bursting element (12), wherein pressurized gas can burst the bursting element for discharging the powder. Preferably, the cross section of a gas supply to the storage chamber controls the gas flow during dispensing of the powder. The storage device comprises multiple storage chambers and associated ducts or nozzles, so that each dose of powder can be dispensed through a separate duct or nozzle. 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. Preferably, the gas pressure reaches or exceeds a peak value before the bursting element bursts and, then, the powder is dispensed by a lower gas pressure.
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 comprises 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:
The invention relates to a method for enclosing a metered, dry powder medication dose comprising at least one active pharmaceutical ingredient (API) and a metered dose of at least one dry powder excipient in a common space of a dose container. The deposited doses in the common dose container constitute a medical product. The method and the medical product are effective in raising the emitted medication dose output and improving the therapeutic efficacy when the doses are delivered together from a dry powder inhaler.
