内視鏡の通気装置。 The outer shell is used to protect built-in light guides and other internal components of the endoscope, and to maintain airtightness and liquid tightness. , and a ventilation connector portion having a ventilation valve body whose outer end surface is slidably fitted into the cylindrical valve body so that the ventilation valve body cannot be inserted into the cylindrical valve body when the valve is closed; The ventilation valve element operating rod, which is always urged toward the outer end surface of the cylindrical body and whose head always protrudes from the outer end surface of the cylindrical body, is maintained in an airtight and liquid-tight state. The venting valve operating device section which is slidably fitted is brought into close proximity to each other, and the cylindrical valve body and the venting valve operating device section are inserted and fixed at the base sides of the cylindrical body, respectively. The inner end of the ventilation valve element in the ventilation connector part inserted into the outer shell by the inner end of the ventilation valve element operating rod of the ventilation valve element operating device part is inserted into the outer shell. The venting valve body is connected in a freely interlocking manner so that the venting valve body can be slid within the cylindrical valve body by pushing the venting valve body operating rod, thereby communicating the inside of the endoscope with the outside world. Endoscope ventilation device.
