Abstract:
A dispenser for discharging an in particular granular or powdery substance by blow-out, has a blow-out duct, and a suction line opening into the blow-out duct for sucking the substance into the blow-out duct. A positive air pressure can be built up in a duct section arranged upstream of the blow-out duct and closed in the direction of the blow-out duct by a valve opening in a pressure-dependent manner, for pressure-controlled formation of a blow-out stream in the blow-out duct. A method for emptying a substance reservoir having a freeze-dried substance sucks the substance out of the substance reservoir, using a suction air stream opening into a blowing stream, and discharges the substance. A sucking/blowing dispenser is used for emptying a substance reservoir having a freeze-dried substance.
Abstract:
A system for coating a target surface employs a bottle for containing the texture material and a spray pump assembly. A resilient member is supported by a pump housing to define an outlet opening. A collar member is supported by the pump housing. The resilient member is normally in an undeformed configuration in which the outlet opening defines a first cross-sectional area. Moving the collar member relative to the pump housing causes the collar member to act on the resilient member to deform the resilient member from the undeformed configuration to a deformed configuration in which the outlet opening defines a second cross-sectional area, where the second cross-sectional area is greater than the first cross-sectional area.
Abstract:
A method and device for intradermal delivery of a reconstituted medicament. The device includes a chamber, which is in fluid communication with a microdevice, e.g. microabrader or one or more microneedles. A cartridge containing the medicament may be located within said chamber. At least one burstable membrane retains a medicament within the housing. The method involves the steps of positioning the device at a delivery site on the skin of a patient and intradermally administering the medicament by dispensing a diluent from a diluent source an through inlet port to rupture the membranes, reconstitute the medicament and deliver the reconstituted medicament through the microdevice to the dermal region of the skin.
Abstract:
A medicament delivery device for administering a medicament to a user includes a medicament reservoir and an entrance port and an exit port each disposed adjacent the reservoir. A gas chamber disposed adjacent the entrance port. The device includes a pressurizing mechanism operable to pressurize said gas chamber to at least a prescribed pressure. A first frangible membrane extends across the entrance port and separates the reservoir from the gas chamber. A second frangible membrane extends across the exit port. When the pressurizing mechanism is attached, at least one of the first and second membranes is responsive to the prescribed pressure in the gas chamber to burst to allow gas to flow through the entrance port and the reservoir and to carry the medicament through the exit port.
Abstract:
A medicament delivery device for administering a medicament to a user includes a medicament reservoir and an entrance port and an exit port and a gas chamber disposed adjacent the entrance port. The device includes a pressurizing mechanism to pressurize the gas chamber. The device also contains frangible membranes and may include a piercing member. In use, the frangible membranes in the device are responsive to pressure in the gas chamber and are either pierced or burst to allow gas to flow through the entrance port and the reservoir and to carry the medicament through the exit port.

Abstract:
A medicament respiratory delivery device including a housing having a chamber, an inlet and an outlet generally coaxially aligned with the chamber, wherein the chamber includes a medicament cartridge having a body including a generally cylindrical passage extending through the opposed ends of the cartridge generally coaxially aligned with the inlet and outlet of the housing having thin burstable polyolefin membranes having a burst pressure of between 1.2 and 10 atmospheres stretched taut over the ends of the cartridge, such that fluid delivered to the inlet ruptures the membranes, entraining medicament contained within the cartridge passage which is delivered to the patient's respiratory system through the outlet. The method of forming the cartridge includes stretching out and bending a membrane to one end of the cartridge, preferably by heat bonding, filling the cartridge with a medicament and sealing the opposed end preferably with a second burstable membrane by stretching out a membrane over a convex surface and heat bonding.
Abstract:
Dosing device with application rounded cone or top. A dosing device with an application top containing at least one application opening, as well as a supply device which, when operating, leads a first medium through at least one medium channel from a medium reservoir to the application opening is known. According to the invention, at least one discharge opening for at least one further medium is provided in the application top adjacent to the application opening and within the application top at least one flow channel for the at least one further medium leads to the discharge opening.
Abstract:
A dry powder inhalator for delivering a precise dose of a medicament contains a mesh disc impregnated with a series of spaced, medicament doses about the disc periphery. The inhalator is armed by manually retracting a finger pull extending downwardly from the bottom of the inhalator housing or rotating the bottom of the housing. The user inserts a mouthpiece on the housing into the mouth and inhales. This causes a chamber in the housing under a diaphragm to evacuate, thereby pulling the diaphragm down onto a knock out lever. The pivoting of the lever enables release of a piston into a cylinder which first compresses, and then dispenses a reduced volume of air at high pressure in a burst up through the medicament disc. When the burst of air hits the impregnated disc, the dose is forced out of the mesh's interstices, producing a cloud of the drug in its powdered form, which is inhaled by the user.
Abstract:
An arrangement has a hand-operated piston pump mountable on a neck of a bottle, and having a first portion outwardly embracing the neck and a second portion inwardly extending into the neck of the bottle. The first portion of the piston pump overlaps the neck over at least a part of its height and is supported by the same. The second portion is formed as a ring-shaped collar. For sealingly connecting the second portion to the neck of the bottle, there is provided as a rubber stopper located between the outer surface of the second portion of the piston pump and the inner surface of the neck of the bottle. The second portion may be provided with an inner thread which can mesh with an outer thread of the neck serving for screwing on a threaded cap. A member is further provided for detachably connecting a drink container to the arrangement so that the liquid withdrawing from the bottle travels directly into the container. The piston pump is a compressed air-operated pump and has an interruptable system of channels provided with an air inlet valve and an air outlet valve. The air inlet valve is formed on a piston of the piston pump, and the air outlet valve is formed on the second piston of the latter.
