  • Patent number: 8876767
    Abstract: The ear irrigation device for the removal of earwax integrates a fluid injector assembly with a fluid container (2) which is loaded and discharged by means of a guided rod (3) and plunger (4) assembly with bidirectional linear sliding through its inside, arranged in the container (2), which it divides into a front chamber (2a) and a rear chamber (2b), an actuating element (5) to move the rod-plunger assembly (3, 4) to said retracted position, a retaining element (13) to retain it, and a nozzle portion (6) for discharging by ejection the fluid of the front chamber (2a) of the container (2) having been provided. A handgrip (7) with a trigger (8) controls the retaining element (13) to release the rod-plunger assembly (3, 4) and allow it to move towards said extended position. The rod (3) of the plunger (4) is hollow and houses a fixed axial guide element (10) and a spring (12) coaxial to the axial element (10).
