Abstract
The present invention relates to a dispenser for dispensing medications into the nostril. The device has a number of advantageous features. First, the device includes air grooves in the spray head to allow the drawing in of air into the nostril during dispensing, to assist in the intake of the dispensed medication. Second, the device contains a mechanism for varying the amount of the dose dispensed. This feature is advantageous in that it allows an accurate metered dose to be dispensed, while still allowing flexibility in the size of the dose dispensed. The device can also have indicia for indicating when the last dose was dispensed, and can include a disinfecting feature for the spray head. The device can also have a gripping feature which spaces the fingers from the nostril into which medication is dispensed.
Claims10
A device for dispensing metered quantities of material as either liquid or spray comprising:
- a container holding a quantity of material to be dispensed:
- a pump for dispensing material from an interior of said container, said pump including a pump stem for delivering liquid from said pump to an exterior of said container;
- a housing, said container being mounted for reciprocal movement in said housing, said housing including a spray passage, said pump stem engaging said spray passage;
- a pump stroke limiting device, said pump stroke limiting device being mounted between said container and said housing, said pump stroke limiting device limiting an amount of reciprocal movement of said container in said housing to thereby control a length of stroke of said pump, said pump stroke limiting device comprising a plurality of elements, each said element being of a different configuration than any other said element, said elements being adapted for mounting on said pump stem, one of said elements interacting with a portion of said container adjacent said pump stem and a portion of said housing adjacent said pump stem when mounted on said pump stem, to thereby limit an amount of reciprocal movement of said container in said housing;
- and
- a driving piston connected to said container and mounted for reciprocal movement in said housing, whereby force applied to said driving piston reciprocates said container in said housing, said driving piston comprising indicia for indicating the time, date, and quantity of the last dispensed dose, said driving piston further comprising a hub and said indicia comprises a plurality of rotatable rings mounted on said hub.
