A woven or non-woven screen mesh disc impregnated at spaced locations along its circumference with a dose of powdered medicament. The disc is selectively indexed so as to present the impregnated doses of medicament seriatim between a pair of holes in an upper and lower pressure plate in an inhalator. Air is forced through the holes in the pressure plates and the encapsulated screen mesh to entrain a dose of the powdered medicament, which is then inhaled through a mouthpiece, by the patient-user. Because the powdered medicament is impregnated into the screen mesh, the air impinging upon the mesh and the powdered medicament will cause the medicament to break up as it is pressed up against and passed through the mesh infrastructure to aerosol or atomize the same so that the medicament is presented in appropriate particle sizes for maximum benefit when inhaled.

Dry powder inhaler medicament carrier

A carrier impregnated at spaced locations along its circumference with a dose of powdered medicament. The carrier is selectively indexed so as to present the impregnated doses of medicament seriatim between a pair of holes in an upper and lower pressure plate in an inhalator. Air is forced through the holes in the pressure plates and the encapsulated dose on the carrier to entrain a dose of the powdered medicament, which is then inhaled through a mouthpiece, by the patient-user. The powdered medicament is embedded in and across interstices in the carrier formed by intersecting and sometimes offset depressions on each surface of the carrier, providing corners and surfaces to cause the medicament entrained in the air stream to break up as it is pressed up against and passed through the carrier infrastructure to aerosol or atomize the same so that the medicament is presented in appropriate particle sizes for maximum benefit when inhaled.

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.

A fluid delivery device and method of delivering fluid is provided. The device comprises a delivery member including a member for creating a vacuum pressure, to suck fluid into a reservoir, and for expelling fluid from the reservoir. A body is provided including a first opening, a second opening, and a third opening, the interior of the body defining a first fluid pathway from the first opening to the second opening and a second fluid pathway from the second opening and a second fluid pathway from the second opening to the third opening. The delivery member is coupled to the second opening. A fluid source is coupled to the first opening. A fluid conduit is coupled to the third opening for allowing the device to deliver product to a patient. The first and second fluid pathways are defined in part by walls that define a central cavity and a diaphragm located therein. The diaphragm closing both the first and second fluid pathways when it is in a first, static position and opening the first pathway when the delivery member creates a vacuum pressure, while maintaining the second pathway in a closed position. When the delivery member creates a positive pressure, the second pathway is opened while the first fluid pathway is maintained in a closed position.
