Abstract: A disposable package, tape, and cassette are provided which makes it possible to hold and disperse therefrom liquid, flowable formulations including aqueous formulations (solutions or dispersions with particles less than 0.25 microns in diameter) of a pharmaceutically active drug. In one embodiment formulation is packaged in individual dosage unit containers which containers are preferably interconnected. The package is designed to be integrated into a cassette which can be loaded into a dispersing device capable of individually opening dosage unit containers and aerosolizing the contents through a porous membrane, into a mouth piece on the cassette, for delivery to a patient. In addition to and alongside of each porous membrane, the package may include one or more openings through which air is forced in order to aid in avoiding the accumulation of aerosolized particles.

Abstract: Liquid, flowable formulations including aqueous formulations of a pharmaceutically active drug are packaged in individual dosage unit containers which containers are interconnected to form a cellular array designed to be integrated into a dispensing device capable of individually opening dosage unit containers and aerosolizing the contents through a nozzle for delivery to a patient. The cellular array is comprised of a plurality of containers with each container having an opening(s) thereon from which a drug-containing formulation may be aerosolized. The dispensing device is a hand-held, self-contained, portable device comprised of a means for removing covers from the containers and automatically dispensing the formulation from individual containers, preferably in response to a signal obtained as a result of measuring the inspiratory flow of a patient.

Abstract: A device is provided which creates aerosolized particles by forcing a formulation of drug in a carrier through a nozzle (which nozzle may be in the form of a porous membrane) into a channel to a patient for inhalation. While in the channel energy is added to the particles in an amount sufficient to evaporate carrier and thereby reduce particle size. The amount of energy added can be adjusted depending on factors such as the particle size, the amount of the carrier to be evaporated, the water vapor content of the surrounding air and the composition of the carrier. Energy may be added in an amount sufficient to evaporate all carrier and thereby provide particles of dry powdered drug to patient which particles are uniform in size regardless of the surrounding humidity and smaller due to the evaporation of the carrier.

Abstract: A composite pre-laminated tape is provided having at least one tape backing (13) of a porous paper coated on one face with a release coating (15) of a solventless, radiation-cured silicone applied directly to the paper.

Abstract: A method of calibrating the output of a transducer in a flow path through which a medication is delivered from a hand-held metered dose inhaler is disclosed. The transducer senses flow rates of human breath during inhalation and exhalation through a portion of a flow path in the inhaler. The flow rates have two non-linear flow characteristics in opposite directions. The flow path portion provides flow rate measurements representative of flow paths of the entire system. The method makes it possible to precisely calibrate so that precise doses of medication can be repeatedly delivered to a patient by inhalation.

Abstract: The childbirth-assisting device uses an automatically synchronized expandable pneumatic girdle-to externally augment the secondary force of labor. The pneumatic girdle is fitted around the abdomen of the woman and the girdle is inflated to create a downward pressure on the abdomen when a contraction occurs. The synchronization of the girdle's inflation and the contractions is provided by an electronic controller which receives a signal from an intra-uterine monitor indicating a contraction and causes the girdle to inflate at a certain rate until a preset intra-uterine pressure is attained. Once the intra-uterine pressure reaches the pre-set pressure, the girdle pressure is maintained until the offset of the contraction is detected, at which time the girdle is deflated.
