A fluid dispensing device is disclosed which has interfitting pump and reservoir modules, with unique releasable tight-fitting coupling mechanism incorporated into the opposed surfaces of the modules. Use of the two interfitting modules permits repeated re-use of the pump module containing the permanent electrical component, with a plurality of seriatim reservoir modules. Only the reservoir module needs to be sterilized. The battery power for the pump can come from a battery positioned within the pump module, which may be used with two or more reservoir modules, or within each reservoir module, which is used only with that single reservoir module. Pumping rate may be fixed or controllable. The coupling mechanism can be central of the device or off-center and is manually operable. The device may be used to provide medications, prophylactics, hormones, drugs, other treating agents for disease or dysfunction, vitamins, minerals, dietary supplements, biological compositions, fragrances, insecticides or vaporizable compounds which mask or eliminate undesirable odors in the ambient environment.

[ We claim:] [1.] A fluid dispensing device comprisinga reservoir module in a first housing, comprising an enclosed fluid containment chamber having an interior surface, a reservoir inlet port providing fluid communication from an exterior of said first housing to an interior of said chamber and a reservoir outlet port providing fluid communication from the interior of said chamber to the exterior of said device;a pump module in a second housing, comprising a fluid pump, operating means for control and operation of said pump, and a pump fluid outlet port providing fluid communication from said pump to the exterior of said second housing;coupling means for detachably joining said first housing containing said reservoir module and said second housing containing said pump module together and simultaneously separably aligning said reservoir inlet port and said pump fluid outlet port; andsaid alignment of said reservoir inlet port and said pump fluid outlet port creating fluid conduit means for providing fluid communication for a first fluid emerging from said pump to pass into said reservoir module and therein cause regulated expulsion of a second fluid within said reservoir through said outlet port, said reservoir inlet port and pump fluid outlet port cooperating with said coupling means to maintain said fluid conduit free from leakage of said first fluid during passage between said first housing containing said reservoir module and said second housing containing said pump module of said device.
