  • Patent number: 4579597
    Abstract: In a method of cleaning an endoscope, the open ends of an air/liquid supply valve cylinder, a suction valve cylinder, and a gas supply valve cylinder which are arranged in a control section of the endoscope are closed by stops. An air supply channel, a liquid supply channel, a suction channel, and a gas supply channel of the endoscope open at one end to a connector mounted on the distal end of the light guide cable of the endoscope. The connector is submerged in the liquid held in a tank. A cap is mounted on the distal end of the insertion section so that a nozzle communicating with the channels and a suction opening communicating with the suction channel open to the interior of the cap. The cap is connected to a suction pump by a suction tube. The pump is operated, thus sucking the liquid from the nozzle and suction opening through the four channels and the three cylinders, thereby cleaning the interiors of these channels and cylinders.

  • Patent number: 4526623
    Abstract: In a method of cleaning an endoscope, a stop having a communication path is mounted on the open ends of an air/liquid supply valve cylinder and a suction valve cylinder of the endoscope so that liquid may flow between the valve cylinders through the communication path. One end of a suction channel, which opens to the distal end of an insertion section of the endoscope, is connected to a liquid tank through a liquid supply tube. An air supply pump is connected to the tank. The pump is operated in this state and supplies the liquid held in the tank to the one end of the suction channel. The liquid supplied to the one end of the suction channel is discharged from a nozzle at the distal end of the insertion section and the other ends of the suction channel, an air supply channel and a liquid supply channel, which open to a connector mounted on a light guide of the endoscope, through the three channels and the valve cylinders, thereby cleaning the interior of these channels and valve cylinders.

  • Patent number: 4525220
    Abstract: In a method of cleaning an endoscope, the open end of a suction valve cylinder, arranged within a control section of the endoscope, is closed by a stop. A cap is mounted on the distal end of an insertion section so that liquid may flow between a nozzle and a suction opening which are arranged at the distal end of the insertion section. The nozzle communicates with an air supply channel and a liquid supply channel, and the suction opening communicates with a suction channel. A stop is mounted on the open end of an air/liquid supply valve cylinder arranged in the control section, and a syringe is connected to the stop. The piston of the syringe is pushed, thus supplying liquid in the cylinder of the syringe into the cylinder and discharging the liquid from the other ends of the three channels through the channels and the valve cylinders, thereby cleaning the interiors of these channels and valve cylinders with the liquid.

  • Patent number: 4323304
    Abstract: A device for fitting an attachment to an endoscope ocular section comprises a cylindrical receptacle which is set in the endoscope ocular section and has an end face, an adapter which is set on the ocular section attachment and fitted around the cylindrical receptacle by rotation, a coupling ring which is rotatably set in the adapter and has an end face capable of being pressed against the end face of the cylindrical receptacle, and connection mechanism for connecting the coupling ring and cylindrical receptacle together in a state prevented from being moved relative to each other. Provision of the connection mechanism prevents the end faces of the cylindrical receptacle and the coupling ring from sliding over each other, thereby eliminating the possibility that a coeliac observation is obstructed by the appearance of a gloss on the end face of the cylindrical receptacle due to its rubbing.
