ABSTRACT:
An improved liquid dispensing device having particular utility as a surgical scrub and/or swab unit is characterized by a cartridge which is slidable in a rigid handle and rupturably by a spike when slid within the handle to a predetermined degree. Fluid from the ruptured cartridge flows from within the handle to within a sponge through apertures which permit free flow of the dispensed fluid. The handle may be provided with longitudinally-extending slots to facilitate compression of the handle and the cartridge disposed therein. A check valve may be included in the hollow spike passage to prevent back flow of liquid from the sponge and dispensing chamber into the cartridge.
