Abstract

A pump-type dispenser (100) for dispensing predetermined doses of medicament in droplets or in spray form to the nasal passage has a rigid vial for medicament, a one-way actuation mechanism (1103), a one-way valve mechanism (3105) in the nozzle area (310), and a spring element (22), both the valve mechanism and the spring element being formed as integral portions of the pump body (3111).A nasal screen (102) aligned with the dispenser nozzle hides the nasal area from public view. The one-way actuation mechanism enables the user to load and dispense a uniform quantity of medicament with a uniform actuation force and speed via a single continuous motion of the actuation mechanism upon application of a very small force on the actuation mechanism by the user. The one-way valve mechanism ensures a one-way movement of medicament from the dispenser, thereby preserving substantially perfect steriliy of the medicament in the dispenser.

Claims

CLAIMS:
1. A pump mechanism for use in a medicament-dispensing system having a vial for holding a volume of medicament, a deformable body portion for providing spring action to said pump mechanism, and a nozzle portion through which said medicament is emitted, which comprises:

a pump sleeve positioned within said deformable body portion, said sleeve having a dosage cavity of a predetermined volume for collecting medicament from said vial, said dosage cavity being connected to said nozzle portion, said sleeve also having a fluid-inlet orifice for channeling said medicament into said dosage cavity; and a piston at least partially and slidably positioned within said pump sleeve for emitting said medicament from said dosage cavity via said nozzle portion, said piston being operationally coupled to said deformable body portion; and at least one O-shaped ring on annular portion of said piston and slidably engaging said pump sleeve, wherein said O-shaped ring provides a fluid-tight seal.
