International ClassB67D 005/00AbstractThe present invention relates to a dispenser for dispensing medications into the nostril or intravenously. The device has a number of advantageous features. First, the device includes a pump in the outer package, so that it may be used with conventional medication packaging. Second, it includes a stop mechanism for allowing adjustment of the dose to be dispensed. Finally, the device is adapted to be used for both nasal and intravenous dispensing, via a replaceable spray passage or injection needle. 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. The package is preferably clear so that the user can determine the quality of the medication being dispensed. The device is particularly useful for dispensing medications such as insulin.Field of SearchWITH RECORDER, REGISTER, INDICATOR, SIGNAL OR EXHIBITORComprising an adjustable stop or stops INSPECTION DEVICES Moving relatively to trap, impeller or valve to cause discharge Graduated transparent container or trap Adjustable stroke pump piston, pulsator or follower Enclosing cover for actuating parts of discharging means Jacketed WITH MATERIAL TREATMENT OR CONDITIONING MEANS Plural Plural scale With discharge volume varying means Plural Interchangeable, removable or selectively usable discharge assistant or element thereof Container with follower Cap With discharge assistant Mounted for relative motion With container handle or handgrip PLURAL INTERCHANGEABLE DISCHARGE MODIFIERS, OUTLET ARRANGEMENTS OR COUPLING MEANS Selectively arrangeable outlet means Assembly or disassembly feature | |
