Abstract: A nasal spray apparatus for simultaneously administrating metered amounts of multiple medicaments includes chambers for separately storing incompatible medicaments, such as an antihistamine and a steroid. Reciprocal piston pumps allow the medications to be sprayed into the user's nasal cavity. Two pumps can be used to separately transfer the medicaments to a receptacle where they can be initially mixed just prior to administration. A small volume receptacle is used to reduce the amount of mixture remaining after each stroke of the nasal spray apparatus. A check valve can be associated with each pump to further reduce medicament mixtures from cross contamination within storage chamber preparations. Collapsible components, including collapsible storage chambers or balloon capacitors can be employed to compensate for vacuums and back pressures as the medicaments are pumped to a spray nozzle.

Abstract: An IV manifold includes a plurality of injection/aspiration ports and has an elongate configuration with a width greater than the diameter of the ports. A flow channel is formed between mating members of a housing and provided with a U-shaped configuration. Projections along the flow channel direct fluid flow into valve cavities associated with the ports to clear dead spots around the valve elements. A check valve included in the manifold tends to direct high pressures against the valve elements which respond by forming surface seals thereby avoiding deformation. An aspiration port can be formed with a second seal disposed on the side of the valve element opposite the first seal. Opening this second seal by negative pressure in the lumen of the port provides for the aspiration of fluids in the flow channel. Two-way aspiration can be provided by a valve having a cage with or without compressible characteristics to accommodate low tolerance fittings.
