Groove at three places that the periphery of valve body 86 forms embeds the second O-ring seals 102, the 3rd O-ring seals 104 and the 4th O-ring seals 106 that has as sealing mechanism.That is, as shown in Figure 4, the position of the stream that radially extends in clipping the stream 98 of supplying gas is equipped with the second O-ring seals 102 and the 3rd O-ring seals 104, is equipped with the 4th O-ring seals 106 in the base portion 82 side end positions of valve body 86.Perimembranous is close under the state of butt in the pipe of the peripheral part of the second above-mentioned O-ring seals 102, the 3rd O-ring seals 104 and the 4th O-ring seals 106 and valve body 86 and guiding tube 84, and valve body 86 moves in guiding tube 84 interior slips.
Valve body 86 by spring 88 application of forces, and is pressed against a end face (outside side pipe inner face) in the pipe of guiding tube 84 when effect does not have external force usual.On the other hand, when the external force of the active force of antagonistic spring 88 put on valve body 86, valve body 86 slided mobile along guiding tube 84, and spring 88 is along axial shrinkage.In addition, when removing external force, under the effect of the active force of spring 88, valve body 86 is pressed against the end face (outside side pipe inner face) in the pipe of guiding tube 84 again.
Endoscope's adapter 62 according to such structure, when under the effect of the active force of spring 88, making the end (outer side end) 116 of valve body 86 be pressed against guiding tube 84, by the second O-ring seals 102, the 3rd O-ring seals 104 and the 4th O-ring seals 106 cut off guiding tube peristome 96, the inner space 56 of the stream 98 of supplying gas, guiding tube perforate 99 and endoscope 10 separately between ventilation, thereby suitably guarantee airtight watertight (airtight) state of inner space 56.On the other hand, if it is mobile via guiding tube perforate 99 valve body 86 to be slided, and guiding tube peristome 96 is connected with the stream 98 of supplying gas (along the stream that radially extends of valve body 86) of valve body 86, then the inner space 56 of endoscope 10 is communicated with via endoscope's adapter 62 (guiding tube peristome 96, the stream 98 of supplying gas, primary flow path 100 etc.) with outside.
In addition, the allocation position of connected entrance 58 and endoscope's adapter 62 does not limit especially, and is for example shown in Figure 6, can set connected entrance 58 and endoscope's adapter 62 at LG adapter 18.Namely, handle operation section 12 or the LG adapter 18 higher by the rigidity in the member of formation of endoscope 10 arrange connected entrance 58, can be in the situation that do not bring impact that the airtight inner space of endoscope 10 suitably is communicated with the outside on insertion section 14 or Universal automatic cable 16 desired flexibilities or hardness (rigidity).But, if can guarantee insertion section 14 or Universal automatic cable 16 desired flexibilities or hardness (rigidity), then also can be in the insertion section 14 or Universal automatic cable 16 set connected entrance 58 and endoscope's adapter 62.The arbitrarily position that can be communicated with in the inner space with endoscope 10 like this, arranges connected entrance 58 and endoscope's adapter 62.
<sterilization bag 〉
Then, the band ventilation adapter of the accommodating endoscope 10 sterilization bag 150 with opening is described.
As shown in Figure 1, wrap the 150 adapter aperture portion 152 that are formed with inside and outside connection in sterilization, embed to have with ventilation adapter 170 in this adapter aperture portion 152 and be close to aperture portion lining (Block Star シ ユ) (the closed area section) 154 that engages.
This aperture portion lining 154 seamlessly is close to joint with respect to adapter aperture portion 152, and is airtight with remaining between aperture portion lining 154 and the adapter aperture portion 152.In addition, aperture portion lining 154 with insert the ventilation adapter 170 described later that links and be close to and keep airtight (liquid-tight).For example, the internal diameter of the peristome by making aperture portion lining 154 is identical with the insertion section external diameter of ventilation adapter 170, can keep aperture portion lining 154 and ventilate airtight between the adapter 170.
As the material of aperture portion lining 154, can be fit to use the good elastic components of close property such as rubber.In the situation that consist of aperture portion lining 154 by elastic component, make the internal diameter of peristome of aperture portion lining 154 slightly less than the insertion section external diameter of ventilation adapter 170, thereby can utilize the elasticity of aperture portion lining 154 adapter 170 of will ventilating to be inserted in the aperture portion lining 154.In this case, can make the air-tightness between aperture portion lining 154 and the ventilation adapter 170 more reliable.
In addition, the characteristics such as the position of the other parts of sterilization bag 150 (be used for accommodating endoscope 10 accommodate opening etc.), shape, size, material do not limit especially, but are preferably the sterilization bag 150 that uses under can the high temperature and high pressure environment when autoclave sterilization described later.Therefore, can appropriate combination have the common flexible plastic of high temperature high voltage resistant characteristic or non-woven fabrics etc. and consist of sterilization bag 150.The sterilization bag 150 that has anti-autoclave sterilization property (high temperature high voltage resistant) by use makes and utilizes the convenience of the present invention of ventilation adapter 170 to significantly improve, and can suitably take care of endoscope 10 when utilizing under the environment of cleaning during from sterilization.
<ventilation adapter 〉
Then, the ventilation adapter 170 with endoscope's adapter 62 links that are housed in the endoscope 10 in the sterilization bag 150 is described.
Fig. 7 is the cutaway view that endoscope's adapter 62 of ventilation adapter 170 is not installed, Fig. 8 is mounted in the cutaway view of the ventilation adapter 170 on endoscope's adapter 62, and Fig. 9 is the stereoscopic figure of an end (with the end of endoscope's adapter 62 links) of ventilation adapter 170.In addition, simple and clear in order to make diagram in Fig. 7 and Fig. 8, and the part of the symbol that will mark in the element of endoscope 10 (endoscope's adapter 62 etc.) or sterilization bag 150 is omitted.
As shown in Figure 8, ventilation adapter 170 has the structure that external flange 174 forms with respect to the adapter main body 172 of tubular structure, and is provided with the vent passage that is made of primary adapter path 176, adapter blow vent 178 and endoscope junction surface 186 in inside.
Adapter main body 172 has the external diameter roughly the same with the opening diameter of the aperture portion lining 154 of sterilization bag 150, when adapter main body 172 was inserted into aperture portion lining 154, adapter main body 172 was close to aperture portion lining 154 and is consisted of the section of being close to that has formed air tight construction.Especially by making as can slide mobile scope (by the scope shown in the dotted line A of Fig. 8) and have the external diameter roughly the same with the opening diameter of aperture portion lining 154 than the total length of the adapter main body 172 of external flange 174 forward distolateral (endoscope's adapter 62 sides) configuration of ventilation adapter 170, mobile thereby even ventilation adapter 170 slides along aperture portion lining 154, also can be airtight with remaining between aperture portion lining 154 and the ventilation adapter 170 (adapter main body 172).
On the other hand, external flange 174 has the large diameter of opening diameter than the aperture portion lining 154 of sterilization bag 150, is configured in the outside of sterilization bag 150 (aperture portion linings 154) when the adapter 170 of will ventilating is installed on endoscope's adapter 62.The stopper that this external flange 174 moves with respect to the slip of aperture portion lining 154 as ventilation adapter 170 and bring into play function, the external flange 174 in the outside by being configured in sterilization bag 150, adapter 170 integral body that can prevent from reliably ventilating are accommodated the situations in the sterilization bag 150.
Be formed with chimeric endoscope junction surface (receiving space) 186 of accommodating endoscope's adapter 62 in an end of ventilation adapter 170 (being configured in the end in the sterilization bag 150).Be provided with the chimeric pawl 182 of a plurality of (being in this example two) adapters towards the radially inner side arranged opposite at the opening of this end of ventilation adapter 170.By chimeric pawl 182 is inserted into ventilation adapter 170 is rotated with above-mentioned adapter, thereby so that the chimeric pawl 182 of adapter engages with adapter slot 92 as shown in Figure 8, the adapter 170 of will ventilating links with respect to endoscope's adapter 62 and connects.
Endoscope junction surface 186 is be used to the peristome of accommodating endoscope's adapter 62, and the internal perisporium at endoscope junction surface 186 is provided with the 5th O-ring seals 184 in the embedded groove.The 5th O-ring seals 184 is close to endoscope's adapter 62 and endoscope junction surface 186 and both is sealed.
Inside at ventilation adapter 170 is provided with: from the other end (being configured in the end outside the sterilization bag 150) of ventilation adapter 170 to the primary adapter path 176 that extends axially endoscope junction surface 186; Be arranged between primary adapter path 176 and the endoscope junction surface 186 and make between the two a plurality of adapter blow vents 178 of ventilation; Diametrically the kernel of section position adjacent with adapter blow vent 178 towards the endoscope junction surface 186 protrude press pad 180.
Have the external diameter below the diameter of guiding tube perforate 99 by pad 180, and have and valve body 86 is slided move to the such axial length in position that is pressed against base portion 82.Therefore, when the chimeric pawl 182 of adapter of ventilation adapter 170 engages with the adapter slot 92 of endoscope adapter 62, be inserted in the guiding tube perforate 99 and push valve main body 86 position (with reference to Fig. 8) that the guiding tube peristome 96 that valve body 86 is slided move to guiding tube 84 is communicated with the stream 98 of supplying gas of valve body 86 by pad 180.In addition, when the adapter 170 of will ventilating took off from endoscope's adapter 62, under the effect of the active force of spring 88, valve body 86 returned to original position, the internal path obturation of the valve body 86 and inner space 56 of endoscope 10 is sealed.Until during this state, will be cut off from the path that ventilation adapter 170 and endoscope's adapter 62 spill to the outside by the 5th O-ring seals 184.
Like this, in this example, be installed on the action of endoscope's adapter 62 by the adapter 170 of will ventilating, vent passage (outside of sterilization bag 150) in the ventilation adapter 170 is communicated with the inner space 56 of endoscope 10, and, the action of taking off from endoscope's adapter 62 by the adapter 170 of will ventilating can keep having kept inner space 56 sealings that make endoscope 10 under the state of air pressure.
Therefore, from valve body 86 begin mobile before can suppress between ventilation adapter 170 and the endoscope's adapter 62 to spill (the ventilation leakage) of outside, afterwards as shown in Figure 8, at the pin 110 of the ventilation adapter 170 link position place with respect to adapter slot 92 engaging of endoscope's adapter 62, the stream 98 of supplying gas of valve body 86 is communicated with the guiding tube peristome 96 of guiding tube 84.That is, the internal path of valve body 86 is opened after the path to the outside is cut off, and therefore can not produce to the ventilation of outside in the connection of adapter 170 with respect to endoscope's adapter 62 of ventilating midway and leak.In addition, when ventilation adapter 170 is moved from link position to removing direction, valve body 86 slides mobile under the effect of the active force of spring 88 immediately to the sealing direction, and can keep adapter air-tight state each other till the mobile end of valve body 86.Like this, according to this example, by the simple connector construction that is consisted of by guiding tube 84, valve body 86, spring 88, can access and to prevent the internally such effect of exceedingly leakage air in space 56.
Like this, in the time of on endoscope's adapter 62 in the adapter 170 of will ventilating is installed on sterilization bag 150, the inner space 56 of endoscope 10 is such as shown by the arrows in Figure 8 with the outside of sterilization bag 150, ventilates via ventilate adapter 170 and endoscope's adapter 62 (primary adapter path 176, adapter blow vent 178, endoscope junction surface 186 (between ventilation adapter 170 and the endoscope's adapter 62), guiding tube peristome 96, the stream 98 of supplying gas, primary flow path 100, the internal flow path of base portion 82 and the connecting piece perforate 91 of base portion 82).At this moment, between endoscope's adapter 62 and ventilation adapter 170, cut off the path that causes to the ventilation leakage of outside by the 5th O-ring seals 184, thereby the state before both soon connections can keep airtight conditions till link position shown in Figure 8.
In addition, based on the slip movement by the valve body 86 of pad 180 spring 88 is shunk vertically, therefore cause the increase of the active force of spring 88.Follow the increase of such active force, engage also grow of power between endoscope's adapter 62 (the adapter slot 92 of annulus 94) and ventilation adapter 170 (the chimeric pawl 182 of adapter), thereby the link between ventilation adapter 170 and the endoscope's adapter 62 becomes more firm.
Figure 10 is the cutaway view of state that the adapter 74 of aeration equipment has been installed at ventilation adapter 170.
This routine adapter 74 possesses: the connector body 196 that forms the tubular of the opening receiving space 195 that the terminal part (outboard end) of ventilation adapter 170 is accommodated; The adapter ventilating part 198 that is communicated with opening receiving space 195.Be provided with the chimeric pawl 192 of a plurality of (being in this example two) adapters towards the radially inner side arranged opposite at the opening of connector body 196.In addition, be provided with the 6th O-ring seals 194 as sealing mechanism of embedded groove at the inner peripheral surface of connector body 196, in the situation that adapter 74 is linked with respect to ventilation adapter 170, the 6th O-ring seals 194 is close to ventilation adapter 170.By the 6th O-ring seals 194, will between ventilation adapter 170 and adapter 74, cause cutting off to the path that the ventilation of outside is leaked, thereby the state that is about to connect from both can keep airtight conditions to link position shown in Figure 10.
Ventilation adapter 170 similarly carries out with the link of the chimeric pawl 182 of adapter of ventilation adapter 170 with the link of adapter 74 and the adapter slot 92 of endoscope's adapter 62.Namely, by chimeric pawl 192 is inserted into adapter 74 is rotated with the adapter of adapter 74, thereby so that the chimeric pawl 192 of adapter engages groove 190 engagings with the adapter of ventilation adapter 170 as shown in Figure 10, adapter 74 is linked connection with respect to ventilation adapter 170.Like this, when ventilation adapter 170 linked with adapter 74, the primary adapter path 176 of ventilation adapter 170 can be ventilated with opening receiving space 195 and the adapter ventilating part 198 of adapter 74.
<autoclave sterilization 〉
One example of then, the autoclave that has used endoscope 10, sterilization bag 150 and ventilation adapter 170 with structure as described above being sterilized describes.Figure 11 is that the flow chart of an example of processing is taken care of in the cleaning of expression endoscope.
(S10 of Figure 11) processed in the cleaning that endoscope 10 after the use implements to make the dirt that adheres to drop.Here said " the clean processing " do not limit especially, it is the concept that can comprise whole processing that the foreign body that is attached in the endoscope is removed, such as not only comprising the so-called cleaning treatment of utilizing brush or detergent to remove the dirts such as body fluid, can also comprise be used to make can't visuognosis antibacterial or so-called the disinfecting of virus extinction.
The endoscope 10 that implements after cleaning is processed is contained in sterilization bag 150 as shown in Figure 12, and is mounted as shown in Figure 13 ventilation adapter 170 (S12).
Namely, between the adapter aperture portion 152 of endoscope's adapter 62 of the endoscope 10 that is contained in sterilization bag 150, sterilization bag 150 and ventilation adapter 170, carry out para-position, the adapter 170 of will ventilating is inserted into the adapter aperture portion 152 from the outside, and an end (at the leading section of the inboard of sterilization bag 150 configuration) of ventilation adapter 170 is linked with endoscope's adapter 62.The airtight inner space 56 of the endoscope 10 that is communicated with endoscope adapter 62 thus, is communicated with (with reference to Fig. 8) with the vent passage of ventilation adapter 170 and the outside of sterilization bag 150.
And, the sterilization bag 150 of accommodating endoscope 10 is put in the autoclave bactericidal unit (not shown) under the state that ventilation adapter 170 has been installed, carry out autoclave sterilization treatment (S14).That is, be installed in the endoscope 10 of in sterilization bag 150, accommodating in an end of ventilation adapter 170, and under the state that configures communicatively via the outside of vent passage and sterilization bag 150 of the other end of ventilation adapter 170, endoscope 10 is implemented the autoclaves sterilization.
Usually, when the autoclave sterilization treatment, endoscope 10 (sterilization bag 150) is placed under the high temperature and high pressure environment, therefore produces large pressure differential between the airtight inner space of endoscope and outside, thereby may cause damaged etc.Yet, in this example, can prevent reliably situation in the inside and outside generation pressure differential of endoscope 10 by ventilation adapter 170.That is, as mentioned above, the inner space of endoscope 10 that ventilation adapter 170 is installed be in can with the open state of outside ventilation, therefore when the autoclave sterilization treatment, between the inner space of endoscope 10 and outside, basically can not produce pressure differential.Therefore, the breakages that the pressure differential in the time of can avoiding the autoclave sterilization treatment by the ventilation adapter 170 of this example causes etc. are unfavorable.
And, after the autoclave sterilization treatment finishes, ventilation adapter 170 is installed the adapter 74 (with reference to Figure 14 and Figure 15) of aeration equipment, carried out the ventilation treatment (airtight check, ventilation etc.) of the inner space 56 of endoscope 10 (S16).That is the endoscope 10 when, the autoclave sterilization treatment finishes is mounted ventilation adapter 170 at the state that is contained in sterilization bag 150.Therefore, need not take out endoscope 10 from sterilization bag 150, can be installed on endoscope 10 via the adapter 74 of adapter 170 with aeration equipment of ventilating.Like this, the state that keeps being contained in sterilization bag 150 after the autoclave sterilization treatment carries out based on the situation of the ventilation treatment of the endoscope 10 of aeration equipment good on operability, and can keep more reliably the sterilizing state of endoscope 10.
In addition, the aeration equipment that connects via adapter 74 does not limit especially, can will utilize the device class of the ventilation of airtightness tester or air interchanger etc. to use as aeration equipment.
Figure 16 is the stereoscopic figure of an example of expression airtightness tester (utensil of supplying gas) 72.Airtightness tester 72 shown in Figure 16 possesses: have the exerciser main body 76 that air pressure is measured meter; Manual pressurization pump 78 in 76 settings of exerciser main body; Base end part is connected and is provided with at leading section the flexible pipe 80 of adapter 74 with exerciser main body 76.By Manual pressurization pump 78 being carried out the dilation operation, the forced air from Manual pressurization pump 78 is sprayed from adapter 74 via flexible pipe 80.Therefore, be installed on ventilation adapter 170 by the adapter 74 with this airtightness tester 72, can be from airtightness tester 72 to endoscope 10 inner space supply gas (with reference to Figure 10), thereby can suitably carry out the bubble-tight check of endoscope 10.Equally, the adapter 74 of air interchanger (not shown) by will regulation is installed on ventilation adapter 170, and the air (dry air) that repeatedly carries out from this air interchanger to endoscope 10 inner space sends and the air of inner space attracts, the dry-off moisture (moisture) effectively thereby take a breath in inner space that can endoscope 10.
When finishing based on the ventilation treatment of aeration equipment, the adapter 74 of aeration equipment is taken off from ventilation adapter 170, endoscope 10 is taken care of (S18) with the state that is contained in the sterilization bag 150 and ventilation adapter 170 is installed.Like this, by endoscope 10 is taken care of with the state that is contained in the sterilization bag 150 and ventilation adapter 170 is installed, even thereby need again based on the ventilation treatment of aeration equipment etc., also can be via ventilation adapter 170 rapidly and suitably reply, very useful.
Afterwards, take off ventilation adapter 170, endoscope 10 is used (S20) from 150 taking-ups of sterilization bag.
<useful effect 〉
As described above, according to the sterilization bag 150 of this example and ventilation adapter 170 (endoscope's keeping apparatus), the ventilation between 150 the outside is wrapped in the airtight inner space that can easily guarantee to be housed in the endoscope 10 in the sterilization bag 150 by ventilation adapter 170 and sterilization.
Therefore, even autoclave when sterilization etc. like that in the situation of ambient pressure change, the ventilation by based on ventilation adapter 170 also can prevent the inner space of endoscope 10 and the generation of the pressure differential between the outside, can prevent the breakage of endoscope 10 etc.
In addition, by connecting airtightness tester at ventilation adapter 170 or supplying gas/air interchanger, can be housed in sterilization and wrap the airtight check of the inner space of the endoscope 10 in 150, supply gas/take a breath.Thus, can be after endoscope 10 being contained in sterilization bag 150 before be about to use, in the situation that do not carry out easily the ventilation treatment (airtight check, ventilation etc.) of the inner space 56 of endoscope 10 from sterilization bag 150 taking-up endoscopies 10.Therefore, can get at before be about to using endoscope 10 keeping in the sterilizing state zone (with reference to Figure 15) in sterilization bag 150 taken care of, thereby can make the Reliability Enhancement of the sterilizing state of endoscope 10.
In addition, ratio external flange 174 forward distolateral (endoscope's adapter 62 sides) in the adapter main body 172 of ventilation adapter 170 has the diameter identical with the opening diameter of the aperture portion lining 154 of sterilization bag 150, therefore even ventilation adapter 170 moves in the 154 interior slips of aperture portion lining, close property/air-tightness between adapter 170 (adapter main body 172) and the aperture portion lining 154 also can suitably keep ventilating.
In addition, be configured in the outside of sterilization bag 150 by the external flange 174 of the adapter 170 of will ventilating, ventilation adapter 170 can be inserted into external flange 174, the installation of adapter 170 with respect to the endoscope 10 in the sterilization bag 150 of can ventilating easily simply from the outside of sterilization bag 150.
In addition, by sterilization bag 150 more small-sized and simple to operate and ventilation adapter 170, the autoclave sterilization that can suitably carry out endoscope 10 reaches the keeping of arriving before being about to use.Therefore, the endoscope's accommodating container (with reference to patent documentation 4) that does not need the relatively large complexity of the ratio preparing to use in the past/propose, about cost aspect, operability, keeping space etc., the combination of the sterilization bag that the present application relates to and ventilation adapter is highly beneficial.
<variation 〉
Above, the preferred embodiment of the present invention is illustrated, but the present invention is not defined as above-mentioned embodiment, also can suitably use for other mode.
For example, in the above-described embodiment, the flange that works as stopper uses the ventilation adapter 170 (with reference to the external flange 174 of Fig. 8) that forms in the outside of sterilization bag 150, but such flange also can be configured in the inside of sterilization bag 150.
Figure 17 is the cutaway view of a variation of expression ventilation adapter 170.In variation shown in Figure 17, replace external flange 174 (with reference to Fig. 8), and the inner flange 175 with diameter larger than the opening diameter of the aperture portion lining 154 of sterilization bag 150 when being installed on endoscope's adapter 62, the adapter 170 of will ventilate is configured in the inboard (inside) that 150 (aperture portion linings 154) are wrapped in sterilization.On the other hand, the anticreep pawl (protuberance) 177 that radially protrudes in the outside of sterilization bag 150 (aperture portion linings 154) is arranged on the adapter main body 172 of ventilation adapter 170, and the diameter that is formed with the position of anticreep pawl 177 in the adapter main body 172 has the large diameter of opening diameter than the aperture portion lining 154 of sterilization bag 150.Anticreep pawl 177 has the elasticity that can extrude from the inside of sterilization bag 150 mobile degree to the outside, and the ventilation adapter 170 of this variation is inserted into the aperture portion lining 154 to the outside by the inside from sterilization bag 150 and installs.According to this variation, the stopper that inner flange 175 and anticreep pawl 177 move with respect to the slip of aperture portion lining 154 as ventilation adapter 170 and bring into play function.That is, in the scope (by the scope shown in the dotted line B of Figure 17) by inner flange 175 and anticreep pawl 177 regulations, ventilation adapter 170 can keep being close to aperture portion lining 154 movement of sliding under the state of airtight conditions.In addition, as long as inner flange 175 is above with the thickness (axial width) that anticreep pawl 177 leaves aperture portion lining 154.
In addition, although the peripheral part of the endoscope of exposing when the use of endoscope directly contacts the examinee, the confined space of above-mentioned endoscope inside can not contact the examinee, is cut off between the confined space of endoscope inside and the examinee.Therefore, as long as guarantee when in fact using in endoscope that the sterilizing state of peripheral part of endoscope is just enough, the confined space of endoscope inside can be said the sterilizing state of the height that the peripheral part of failed call endoscope is such.But the confined space of preferred endoscope inside also is in the sterilizing state with the equal height of the peripheral part of endoscope.Therefore, can be by airtight ventilation adapters 170 of closure mechanism (primary adapter path 176) such as lids.For example, from after the autoclave sterilization to install aeration equipment (adapter 74) during or after the ventilation treatment based on aeration equipment (take off from ventilation adapter 170 adapter 74 after) to until till during the re-using of endoscope 10 during, by closure mechanism ventilation adapter 170 is carried out airtight, thereby the sterilizing state of the inner space 56 of the vent passage of the adapter 170 that can keep well ventilating and endoscope 10.
The closure mechanism of such ventilation adapter 170 limits especially, for example can use and utilize the connector construction that moves with the slip of the same valve body of above-mentioned endoscope's adapter 62 (with reference to Fig. 4).Namely, the valve body that can slide after will be by spring (force application mechanism) application of force is configured in the guiding tube, and when adapter 74 is installed to ventilation adapter 170, the active force of valve body antagonistic spring and the movement of sliding, thus can be communicated with vent passage (primary adapter path 176) in the valve body being communicated with the inside and outside guiding tube peristome of guiding tube.On the other hand, when with adapter 74 from ventilation adapter 170 when taking off, the active force of valve body antagonistic spring and the movement of sliding, thus the vent passage in the valve body (primary adapter path 176) can be cut off from the outside.Like this, the closure mechanism according to the dismounting interlock of the adapter 74 of aeration equipment the airtight of ventilation adapter 170 (primary adapter path 176) and ventilation being controlled can keep the sterilizing state of the airtight inner space of endoscope 10 easily.
In addition, in the above-described embodiment, carried out the autoclave sterilization of endoscope, processed but the present invention can also be applicable to autoclave sterilization sterilization (sterilization) in addition.The endoscope 10 that will be contained in sterilization bag 150 in the sterilization (sterilization) of such other is processed is placed in the situation of environment of pressure oscillation, can effectively prevent from producing in the inside and outside ventilation of endoscope the situation of pressure differential by ventilation adapter 170.In addition, even when only taking care of, by connecting aeration equipment at the ventilation adapter as required, also endoscope can be implemented desired ventilation treatment with the state that is contained in the sterilization bag.
