Abstract

PURPOSE:To remove the pain of a patient by facilitating washing operation, by a method wherein first and second check valves for the inflow of a washing solution are provided while two third and fourth check valves for discharging the used washing solution are provided and a branch passage is further provided and a change-over apparatus connecting a cylinder apparatus is provided. CONSTITUTION:In the washing operation of an organ, the first storage tank 30 and a cylinder apparatus 40 are connected by a change-over apparatus 39. When negative pressure is applied to the interior of the first storage tank 30 by the cylinder apparatus 40, the first check valve 31 is opened and the washing solution from a washing solution tank 29 flows in the first storage tank 30 through a supply passage 28. Subsequently, when the first storage tank 30 is pressurized by the cylinder apparatus 40, the second check valve 32 is opened and the washing solution flows out to the supply passage 28 on the organ side to be injected in the organ from the supply passage 28 inserted in the organ. In order to discharge the used washing solution, the second storage tank 35 and the cylinder apparatus 40 are connected by the change-over apparatus 39 and the third check valve 36 is opened when negative pressure is applied to the second storage tank 35 by the cylinder apparatus 40 to allow the used washing solution to flow in the second storage tank 35 through the discharge passage 33 on the organ side.
