Abstract: A device for filtering a gas stream, having a vessel partitioned into a first stage and a second stage, with an opening between stages. A filter element is positioned in the opening, with ends of the filter element extending into the first and second stages. The first member is removable from the second member while the filter element is positioned in the opening, to allow for replacement with a new clean member.

Abstract: An improved device for containing and administering orally active therapeutic agents is described. A unit dose of a therapeutic agent in free-flowing form is retained and positioned for oral administration in a tube adapted to deliver the dose with a flow of liquid drawn through the tube by normal sipping action of a patient. The combination of small particle size and high flow rates into the alimentary canal allow dosage administration with minimal sensed contact with the oral cavity. The invention is particularly advantageous for the administration of orally active therapeutic agents to pediatric and geriatric patients.

Abstract: A syringe holder for administering the contents of prefilled cartridge-cannula units comprises generally a cartridge holding barrel rotatably connected to a push rod guiding sleeve, and a push rod slidably mounted in the sleeve.

Abstract: A system for the packaging, shipment, storage, and reconstitution of dry pharmaceuticals includes a flexible bag manufactured from two layers of plastic laminated film and a rigid port-forming member. In the system, the package is used for shipment and storage of dry pharmaceuticals and for their reconstitution in a liquid solution and their intravenous administration. A plurality of such packages may be handled as an assembly by flexible plastic strips both during processing and packaging and during the reconstitution of the dry medicine as a liquid solution. The flexible plastic strips are formed with a plurality of cavities. Each cavity of the strip has a plurality of sites located in its central portion and adapted to engage and retain the port-forming member and to protect its opening from contamination. A plurality of such package assemblies can be enclosed within an outer protective bag to provide protection against moisture and the effects of the environment during shipment and storage.

Abstract: A refillable tablet package is provided through the use of a paperboard folder to which are attached removable plastic sheets containing tablets in blister receptacles.

Abstract: A dual compartment mixing vial having a center seal isolating one compartment from the other is provided with a stopper at its open end which embodies a rod that is slidably positioned therethrough. The rod, upon being pushed downwardly, abuts the center seal of the vial and causes it to be displaced, thereby permitting the contents of the two compartments to intermix within the closed vial. An activating cap is provided for preventing accidental movement of the rod and to facilitate intentional movement of it.

Abstract: A collapsible carton and plastic bag container is provided from a single sheet of plastic material and a single layer of paper board which is affixed to the plastic sheet material.
