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.
