Abstract:
A humidification system has a humidification source and a main gases flow path. The main gases flow path has a low pressure region and a high pressure region. In some embodiments, each of the low pressure region and the high pressure region has an aperture. The pressure difference between the apertures promotes a gases flow between the main gases flow path and the humidification source, and results in humidifying the gases in the main gases flow path.
Abstract:
Die Erfindung betrifft einen handbetätigbaren Inhalator (1) zur Ausbringung einer pulverförmigen Substanz, insbesondere einer pharmazeutischen Substanz, mit einer Vorratskammer, einem Austragskanal (13) und einer Dosierkammer (19), wobei der Austragskanal in die Vorratskammer (12) hineinragt und die Dosierkammer (19) und der Austragskanal (13) relativ zueinander bewegbar sind. Um einen Inhalator zur Ausbringung einer pulverförmigen Substanz anzugeben, bei welchem eine vorteilhafte Füllbarkeit der Dosierkammer erreicht ist, wird vorgeschlagen, dass der Austragskanal (13) um eine Drehachse (A) drehbar ist und dass die Dosier kammer (19) im Zug einer Drehung des Austragskanals (13) füllbar ist. Zudem betrifft die Erfindung einen handbetätigten Inhalator (1) zur Ausbringung einer pulverförmigen Substanz, insbesondere einer pharmazeutischen Substanz, mit einer Vorratskammer (12), einem Mundstück (4), einem Austragskanal (13) und einer Dosierkammer (19), wobei die Dosier kammer (19) von einem geschlossenen in einen geöffneten Zustand und umgekehrt versetzbar ist. Auch betrifft die Erfindung einen handbetätigten Inhalator (1) zur Ausbringung einer pulverförmigen Substanz, insbesondere einer pharmazeutischen Substanz, mit einem Austragskanal (13), wobei in dem Austragskanal (13) ein Verwirbelungsmittel (14) angeordnet ist, das eine wendeiförmig verlaufende Wandung aufweist und bei einem Austragen von mit der Substanz versehener Luft zu durchströmen ist.
Abstract:
An inhaler comprising a reservoir of an inhalable composition, a heater to selectably volatilise at least some components of the composition, and a power source arranged to selectively supply electrical power to the heater when the user inhales from the inhaler, the inhalable composition comprising: nicotine or a pharmaceutically acceptable derivative or salt thereof, a glycol and/or glycol ether, and a propellant, wherein the propellant is present in an amount of from greater than 0 %w/w to less than 95 %w/w based on the total weight of the composition.
Abstract:
The present invention provides a device for delivering a predetermined volume of a substance, within at least one body cavity of a subject, comprising: a. a predefined volume for containing said predetermined volume of said at least one substance; b. a delivery end for placement in proximity to said body cavity; said delivery end comprises at least one orifice of diameter D [mm]; c. a valve mechanically connectable to said container, characterized by at least two configurations: ( i ) an ACTIVE CONFIGURATION in which said valve enables delivery of predetermined volume V sub [ml] of said substance; and, ( ii ) an INACTIVE CONFIGURATION, in which said valve prevents delivery of said predetermined volume V sub [ml] of said substance from said container to said body cavity; d. a fluid tight chamber configured to contain predetermined volume V gas [ml] of pressurized gas at a predetermined pressure, P gas [barg].
Abstract:
A flow of gases in a respiratory therapy system can be conditioned to achieve more consistent output from sensors configured to sense a characteristic of the flow. The flow can be mixed by imparting a tangential, rotary, helical, or swirling motion to the flow of gases. The mixing can occur upstream of the sensors. The flow can be segregated into smaller compartments to reduce turbulence in a region of the sensors.
Abstract:
Dose delivery device with partially or fully surrounding cover may be removed to open fluid communication with a dose chamber. The cover may allow an inhaler to be stored in sterile or otherwise in a controlled environment prior to use, and removal of the cover may automatically prepare the inhaler for use.
Abstract:
A device for washing a suspension of cells. The device includes a bowl-shaped basin having a top end and a bottom end and an axis extending from the top end to the bottom end, and an inlet port formed in the basin. The inlet port is positioned at an angle to allow for a wash solution to be injected or delivered into the basin and circulate around the basin about the central axis. A suspension of cells can be washed in the circulating wash solution. The circulating wash solution forces the cells to settle at the bottom of the basin, where they can be extracted.
Abstract:
A method of flowing a medicament comprising dry powder using gas, including preparing a medicament capsule with designated inflow and outflow apertures, introducing a volume of a gas to within a medicament capsule according to one or more release conditions, and releasing a therapeutically effective amount of said powder using said gas. In some embodiments, the medicament capsule apertures are prepared and/or gas delivered to it so that deagglomeration potentially occurs largely within the energetic flow conditions of the capsule, without significant trapping of residual powder by structures such as aperture edge irregularities.
Abstract:
The present invention provides a dry powder inhaler comprising: a reservoir containing a dry powder formulation and an arrangement for delivering a metered dose of the medicament from the reservoir; a cyclone deagglomerator for breaking up agglomerates of the dry powder medicament; and a delivery passageway for directing an inhalation-induced air flow through a mouthpiece, the delivery passageway extending to the metered dose of medicament, wherein the formulation comprises an inhalable β 2 -agonist having a particle size distribution of d10
