ABSTRACT:
An inexpensive adapter enabling the facile manual switching of the fluid uptake port of a standard manually-operated fluid dispensing pump fluid between a plurality of fluid reservoirs. The adapter, which has a low internal dead volume, has an adapter outlet port that is in fluid communication with the fluid uptake port of the fluid-dispensing pump and at least two adapter inlet ports. The adapter inlet ports are in fluid communication with respective fluid reservoirs. The adapter has concentric outer and inner housings. In a preferred embodiment, the outer housing is non-releasably affixed to a fluid dispenser head while the inner housing is releasably affixed to a plurality of fluid reservoirs. The position of the outer housing, which is manually rotated with respect to the inner housing, is determined by means of a spring-loaded detent. Rotation of the outer housing with respect to the inner housing through successive detent stops sequentially fluidly connects the adapter outlet port and, therefor, the fluid uptake port of the fluid dispenser, with one of the plurality of adapter inlet ports which, in turn, are in fluid communication with respective fluid reservoirs.
