ABSTRACT:
A disposable liquid dispensing module in the form of a hollow plastic container for holding liquid, such as a cleaning solution or soap, has at least one liquid level sensing probe permanently mounted in it. The module is made to be inserted into a lavage machine or similar apparatus and includes a connector to which a connection plug having a liquid withdrawal pipe and connectors to the liquid level sensing probe is attached. The pipe is connected to an elongated flexible tube and the connectors for the liquid level sensing probe are connected to flexible wires, so that the plug including these components may be attached to the container outside the lavage machine in which it is used. When the level of liquid falls below a predetermined threshold, a signal is provided to the apparatus indicating that replacement of the container is to be made. The entire module then is withdrawn and the plug to the apparatus is disconnected. The original module is discarded and a new module filled with cleaning solution is attached to the plug and placed in the machine.
