ABSTRACT:
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.
