Fig. 7 is the sectional view of the endoscope's adapter 62 for not installing ventilation adapter 170, and Fig. 8 is mounted in company of endoscope Connect the sectional view of the ventilation adapter 170 on device 62, Fig. 9 is that the ventilate one end of adapter 170 (connects with endoscope adapter 62 The end of knot) stereoscopic figure.In addition, in Fig. 7 and Fig. 8, in order that diagram is simple and clear, and will be in (endoscope of endoscope 10 Adapter 62 etc.) or the element of Packs sterilized 150 on mark symbol a part omission.

As shown in figure 8, ventilation adapter 170 has adapter main body 172 one of the external flange 174 relative to tubular structure The structure that body ground is formed, and be internally provided with by primary adapter path 176, adapter blow vent 178 and endoscope junction surface 186 vent passages for constituting.

Adapter main body 172 has the external diameter roughly the same with the opening diameter of the aperture portion bushing 154 of Packs sterilized 150, When adapter main body 172 is inserted into into aperture portion bushing 154, adapter main body 172 is close to aperture portion bushing 154 and is constituted Define the close to portion of air tight construction.Especially by enable as ventilation adapter 170 slide mobile scope (by Fig. 8 Dotted line A shown in scope) and than the forward side of external flange 174 (side of endoscope's adapter 62) configuration adapter main body 172 total length has the external diameter roughly the same with the opening diameter of aperture portion bushing 154, even if so as to the edge of adapter 170 of ventilating Aperture portion bushing 154 slide movement, it is also possible to by aperture portion bushing 154 with ventilation adapter 170 (adapter main body 172) it Between remain it is airtight.

On the other hand, external flange 174 has the big diameter of the opening diameter of the aperture portion bushing 154 than Packs sterilized 150, When ventilation adapter 170 is installed on into endoscope's adapter 62, configuration is in the outside of Packs sterilized 150 (aperture portion bushing 154). The external flange 174 plays work(as ventilation adapter 170 relative to the mobile stopper of the slip of aperture portion bushing 154 Can, the external flange 174 in the outside by being configured in Packs sterilized 150 can be reliably prevented the overall collecting of ventilation adapter 170 To the situation in Packs sterilized 150.

Chimeric collecting endoscope is formed with the one end (end being configured in Packs sterilized 150) of ventilation adapter 170 The endoscope junction surface (receiving space) 186 of adapter 62.Opening in the end of ventilation adapter 170 is provided with direction Radially inner side multiple (being in this example two) adapters arranged opposite are fitted together to pawl 182.By above-mentioned adapter is embedding Conjunction pawl 182 is inserted in the state of endoscope's adapter 62 (otch 112 (with reference to Fig. 5) of annulus 94) and makes ventilation adapter 170 rotate, so that the chimeric pawl 182 of adapter engages as shown in Figure 8 with adapter slot 92, by adapter of ventilating 170 link connection relative to endoscope's adapter 62.

Endoscope junction surface 186 is the peristome for housing endoscope's adapter 62, in endoscope junction surface 186 Perisporium is provided with the 5th O-ring seals 184 in embedded groove.5th O-ring seals 184 connect with endoscope adapter 62 and endoscope Conjunction portion 186 is close to and seals both.

It is provided with the inside of ventilation adapter 170：(it is configured in outside Packs sterilized 150 from the other end of ventilation adapter 170 End) to the primary adapter path 176 for axially extending to endoscope junction surface 186；Be arranged on primary adapter path 176 with it is interior Between sight glass junction surface 186 and make the multiple adapter blow vents 178 ventilated between the two；Diametrically with adapter blow vent Towards the pushpin 180 of the protrusion of endoscope junction surface 186 at 178 adjacent kernel of section positions.

Pushpin 180 have guiding tube perforate 99 diameter below external diameter, and with will ventilation adapter 170 installing Valve body 86 is set to be slidably moved to be pressed against axial length as the position of base portion 82 when endoscope's adapter 62.Therefore, logical When the chimeric pawl 182 of the adapter of airway adaptor 170 engages with the adapter slot 92 of endoscope adapter 62, pushpin 180 It is inserted in guiding tube perforate 99 and presses valve body 86, makes valve body 86 be slidably moved to the guiding tube peristome of guiding tube 84 96 positions connected with the stream 98 of supplying gas of valve body 86 (with reference to Fig. 8).In addition, when adapter 170 of ventilating connects from endoscope When connecing device 62 and removing, in the presence of the active force of spring 88, valve body 86 returns to original position, the inside of valve body 86 Path is inaccessible and the inner space 56 of endoscope 10 is sealed.Till when the state, will be from by the 5th O-ring seals 184 Ventilation adapter 170 and endoscope's adapter 62 separate to the path that outside spills.

So, in this example, by the way that ventilation adapter 170 is installed on into the action of endoscope's adapter 62, can make to lead to Vent passage (outside of Packs sterilized 150) in airway adaptor 170 is connected with the inner space 56 of endoscope 10, also, by inciting somebody to action The action that ventilation adapter 170 is removed from endoscope's adapter 62, can make endoscope in the state of holding maintains air pressure 10 inner space 56 seals.

Therefore, from valve body 86 start it is mobile before can suppress from ventilation adapter 170 and endoscope's adapter 62 it Between spilling (ventilation leakage) to outside, afterwards as shown in figure 8, the pin 110 in ventilation adapter 170 connects relative to endoscope At the link position of the engaging of adapter slot 92 of device 62, the stream 98 of supplying gas of valve body 86 is opened with the guiding tube of guiding tube 84 Oral area 96 is connected.That is, the internal path of valve body 86 is opened after being separated to outside path, therefore in ventilation adapter 170 will not produce to outside ventilation leakage halfway relative to connecting for endoscope's adapter 62.In addition, work as making ventilation adapter 170 from link position to removing direction when moving, and valve body 86 is in the presence of the active force of spring 88 immediately to closing direction Slide and move, and the mutual air-tight state of adapter is able to maintain that to the mobile end of valve body 86.So, according to this Example, by the simple connector construction being made up of guiding tube 84, valve body 86, spring 88, can obtain preventing from inside Effect as the exceedingly leakage air in space 56.

So, when on endoscope's adapter 62 that ventilation adapter 170 is installed in Packs sterilized 150, endoscope 10 Inner space 56 and Packs sterilized 150 outside as shown by the arrows in Figure 8, via ventilation adapter 170 and company of endoscope Meet device 62 (primary adapter path 176, adapter blow vent 178, endoscope junction surface 186 (ventilation adapter 170 and endoscope Between adapter 62), guiding tube peristome 96, stream 98 of supplying gas, primary flow path 100, the internal flow path of base portion 82 and base portion 82 Connecting piece perforate 91) and ventilate.Now, it is close by the 5th O shapes between endoscope's adapter 62 and ventilation adapter 170 The cut-off of seal 184 causes the path to outside ventilation leakage, so as to shown in the state to Fig. 8 before will connecting from both Airtight conditions can be kept till link position.

In addition, axially contracting spring 88 based on the slip movement of the valve body 86 of pushpin 180, therefore cause spring The increase of 88 active force.With the increase of such active force, (the adapter slot of annulus 94 of endoscope's adapter 62 92) also become strong with the clamping force between ventilation adapter 170 (adapter chimeric pawl 182), adapter 170 is peeped with interior so as to ventilate Link between mirror adapter 62 becomes more firm.
