Irrigator for body cavities
 An irrigator for applying an irrigating solution to internal body cavities. A housing defines a first chamber for holding a supply of irrigating solution liquid for irrigating a body cavity and a second chamber for receiving waste liquid from the body cavity. A first single action pump in the housing receives a measured quantity of liquid from the first chamber and pumps the same into the body cavity. A second single action pump in the housing withdraws waste liquid from the body cavity and discharges the liquid into the second chamber. The first and second pumps are of the piston and diaphragm type, and each is provided with a port in communication with a single common conduit connectable with the body cavity.
