ABSTRACT:
This invention relates to an ear syringe having a built-in pressure regulator valve to control the discharge velocity of fluid issuing from the nozzle of the syringe, regardless of the amount of pressure applied on the bulb of the syringe, to prevent pain in the ear of a user, or possible damage to the ear as a result of squeezing the bulb too hard, or applying a sudden excessive pressure to the bulb.
