Abstract

A portable debridement and irrigation device includes a body structure and a disposable spray nozzle structure and spray reduction cup removably mounted thereon. A battery-powered electric pump device is in liquid transmission connection with the disposable spray nozzle device. A removable and replaceable liquid storage container which holds a sterile liquid is held within a storage container receiving chamber formed within the body structure in liquid transmission connection with the electric pump, and a pump engagement switch is operatively interposed between the battery and the electric pump for engaging and disengaging the electric pump. Finally, a pump speed control device with a limiting device for preventing it from proceeding beyond a predetermined operating setting unless the operator intentionally disengages the limiting device is operatively connected to the electric pump for adjusting the operating speed of the pump and thus the outflow speed of liquid from the spray nozzle.
