PCT No. PCT/SE89/00146 Sec. 371 Date Nov. 5, 1990 Sec. 102(e) Date Nov. 5, 1990 PCT Filed Mar. 17, 1989 PCT Pub. No. WO89/08470 PCT Pub. Date Sep. 21, 1989.Apparatus (2) for liquid flushing of body cavities and/or supplying an active substance to the body cavities includes a piston/cylinder device (3), a device (9,10) for manual actuation of the piston (8) and a nozzle (4) projecting from the piston/cylinder device (3) adapted for insertion of the free end (12) of the nozzle in the body cavity. The nozzle (4) is formed with two separated channels (5,6) each terminating at an outer end in a free end of the nozzle, one of the channels (6) extending in the wall of the cylinder (7) and an inner end terminating at the end of the cylinder immersed in the liquid (b) in a receptacle (1) containing the liquid and connected to the piston/cylinder device, the other channel (5) having an inner end communicating with a space (A) above the liquid in the container (1) and a piston rod (9) having a return spring (11). Upon reciprocating movement of the piston (8) in the cylinder (7), with the open end of the cylinder (7) immersed in the liquid (B), air in the channels (5,6) and at least an essential amount of the air in the body cavity is initially flushed by liquid flowing into channel (6) from the inner end thereof into space (a).
