Then, the operator chemical ind or biology indicator etc. indicator 23 be housed in the inner shell shown in Figure 23.At this moment, the operator rotates the either party's gomphosis part 20 shown in Fig. 2 on one side, Yi Bian it is disassembled, again connector portions 19 is disassembled, the indicator 23 of corresponding kind is contained in the housing body 18, and then above-mentioned connector portions 19 is installed on the housing body 18 with gomphosis part 20.Like this, housing body 18 is inner just to be sealed by separately O-ring seals 21, is contained in its inner indicator 23, with roughly the same the imposing a condition of the pipeline of the endoscope that carries out sterilization processing, perhaps under the needed time conditions of sterilization processing, dispose.
Then, the operator inserts above-mentioned inner shell 3 in the shell 2 shown in Fig. 1 as the crow flies, not allow it be blocked by inner matter.
And operator's pivot stop parts 7 and it is carried out fastening, thereby fix shell 2.
Then, the operator the sterilizing pretest pack for endoscope 1 of Fig. 1 in the pallet or box of expression accommodated in the drawings by the endoscope that carries out sterilization processing, after pallet or box being wrapped with retort pouch and infantees, accommodate in the sterilizer of not representing in the drawings, it is carried out known autoclave sterilization, perhaps EOG sterilization processing.In addition, in the present embodiment,, it is desirable to suitably implement ripple under the germ-resistant situation of vacuum type high steam carrying out according to dick test as sterilization processing.In this case, can replace being applicable to the indicator of ripple with above-mentioned indicator 23, and it is housed in the above-mentioned inner shell 3 according to dick test.
After sterilization processing finishes, the operator with the opposite order of situation that above-mentioned inner shell 3 is housed in the shell 2, the indicator 23 of being accommodated is taken out the effect of affirmation sterilization processing from inner shell 3.
In this case, because above-mentioned sterilizing pretest pack for endoscope 1 constitutes, the condition (temperature and gas concentration) of this inner shell 3 inside is roughly the same with the condition of the pipeline inside of the endoscope that carries out sterilization processing, so can confirm and the roughly the same bactericidal effect of bactericidal effect that in fact carries out the endoscope of sterilization processing by this indicator 23.
In addition, in the present embodiment, also can have such structure, that is,, determine whether to possess the check valve 17A of above-mentioned back-end component 17 according to the endoscope that carries out sterilization processing.Promptly, if carry out the endoscope of sterilization processing is to allow steam enter the type of carrying out sterilization processing between flexible pipe and the pipeline (passage), as long as just steam is set enters the hole, and above-mentioned check valve 17A need be set, enter the hole by means of above-mentioned steam, make the zone and the external communications of the inside of pipeline (pipeline that also comprises first, second pipeline 22A, 22B) in the above-mentioned inner shell 3, shell 2 and first, second flexible pipe 4A, 4B inside, carry out sterilization processing then.
In addition, on the contrary, if carry out the endoscope of sterilization processing is not allow steam enter the type of carrying out sterilization processing between flexible pipe and the pipeline (passage), above-mentioned check valve 17A then is set as shown in Figure 1, make the zone of the inside of pipeline (pipeline that also comprises first, second pipeline 22A, 22B), shell 2 of above-mentioned inner shell 3 inside and first, second flexible pipe 4A, 4B inside, only when negative pressure and external communications, carry out sterilization processing then.
Therefore, according to present embodiment,, just can obtain and the bactericidal effect roughly the same, and can simply and carry out the affirmation of bactericidal effect effectively the bactericidal effect of above-mentioned endoscope by means of being provided with and the suitable test assembly of endoscope structure that carries out sterilization processing.
In addition, the present invention is not limited in above-described embodiment, under the prerequisite that does not break away from the invention aim, can carry out various distortion.
The embodiment 2 of sterilizing pretest pack for endoscope of the present invention then, is described.The sterilizing pretest pack for endoscope of embodiment 2 has such structure,, has the single pipeline resettlement section of accommodating two pipelines that is.Below, to Figure 10, present embodiment 2 is described with reference to Fig. 3.
Fig. 3 is the sketch map of the sterilizing pretest pack for endoscope outward appearance of expression embodiment 2.As shown in Figure 3, the sterilizing pretest pack for endoscope of present embodiment 2 has following part: shell 26 is used for accommodating the inner shell 33 (not representing at Fig. 3) that inside contains indicator; Accommodated the pipeline resettlement section 27 of first pipeline 38 and second pipeline 39 (in Fig. 3, not representing); Check valve 28 before importing sterilization gas, makes the inner space of shell 26 and the inner space of pipeline resettlement section 27, that is, make inner shell 33 around and first, second pipeline (aftermentioned) roughly become vacuum on every side; And connecting portion 29, pipeline resettlement section 27 and shell 26 are roughly coupled together airtightly.
Fig. 4 is the sketch map of the sterilizing pretest pack for endoscope internal structure of expression embodiment 2.As shown in Figure 4, the sterilizing pretest pack for endoscope of present embodiment 2 has in shell 26 inside: inner shell 33; The maintaining part 34 that keeps inner shell 33; And the gas detection section 35 that detects the sterilization gas leakage.In addition, pipeline resettlement section 27 has following part: flexible pipe 37, and by connecting portion 29, its inner space is communicated with the inner space of shell 26, and runs through first pipeline 38 and second pipeline 39; Gas introduction part 40,41 has sterilization gas is imported gas introduction port 40a, 41a in first pipeline 38 and second pipeline 39; And leading section 42, be connected with the end of flexible pipe 37, and have from the gap (aftermentioned) of external lid flexible pipe 37 inside and the function that keeps gas introduction part 40,41.
Flexible pipe 37 has such structure: have flexiblely, constitute with parts that can free bend, have first pipeline 38 and second pipeline, 39 these two pipelines that pipeline can pass.In present embodiment 2, the internal diameter of the pipeline that forms in flexible pipe 37 forms more much greatly than the external diameter of first pipeline, 38 grades, so that at the outer surface of first pipeline 38 and the outer surface of second pipeline 39, and produces the space between the inner surface of flexible pipe 37.On the one hand, function by means of leading section 42 grades, this space and space outerpace are isolated, on the other hand, by connecting portion 29, above-mentioned space is communicated with the inner space of shell 26, and by means of the effect of check valve 28, when the inner space of shell 26 became the substantial vacuum atmosphere, the space part of flexible pipe 37 inside also became the atmosphere of substantial vacuum.
In addition, the same with embodiment 1, though flexible pipe 37 also can be made of shape (diameter), structure and the material identical with the insertion section of endoscope, but, if the rising of first pipeline 38 and the inner wall temperature of second pipeline 39 is identical with the situation of using endoscope insertion part, perhaps compare temperature and be difficult for rising, then also can use other tubular part with this situation.
The same with the second pipeline 22B with the first pipeline 22A among the embodiment 1, first pipeline 38 and second pipeline 39 are the parts that are used in the indicator of sterilization gas importing inner shell 33.Sterilizing pretest pack for endoscope in the present embodiment 2 is the parts that are used to confirm whether to have carried out reliably sterilization processing when endoscope is carried out sterilization processing.Therefore, in present embodiment 2, first pipeline 38, second pipeline 39 have respectively with as the corresponding structure of pipeline that is possessed by the endoscope inside of germicide, and sterilization gas arrive dispose indicator the zone (promptly, the interior zone of inner shell 33) condition, with arrive identical, perhaps also strict than it as the condition of the pipeline mid point that forms on by the endoscope of germicide.In addition, about the contact performance between the interior week of the periphery of first pipeline 38 and second pipeline 39 and flexible pipe 37, only however influence the rising of pipe temperature and sterilization gas by pipe interior pass through bactericidal effect such as performance, no matter be to contact, or contactless state can.
Shell 26 also is used to make the atmosphere that keeps regulation on every side when importing sterilization gas of inner shell 33 when accommodating the inner shell 33 that is built-in with indicator, be the atmosphere that keeps substantial vacuum in present embodiment 2.Specifically, shell 26 has: the case 30 of accommodating inner shell 33; And by means of screw thread in conjunction with etc. be formed at loam cake 31 on the case 30 with freely loading and unloading.In addition, in installation process, in case 30 and the part that loam cake 31 contacts, disposed O-ring seals 36, loam cake 31 is by means of the effect of O-ring seals 36, is fixed in gastight mode roughly and accommodates on the shell 30.
Being configured in the gas detection section 35 in the shell 26, is the parts that are used for judging following situation: whether the sterilization gas that imports in the inner shell 33 by first pipeline 38 and second pipeline 39 leaks into inner shell 33 outsides; Perhaps because the air-tightness of certain parts is impaired, whether sterilization gas invades test assembly inside from the outside by beyond thought part.Specifically, gas detection section 35, be by indicators such as sign that has applied the chemical drugs that the sterilization gas as detected object is responded or CI, and the mechanism of accommodating indicator constitutes, it has following function: when sterilization gas leaks into inner shell 33 outside, by the reaction of indicator for displaying regulation, detect the leakage and unexpected intrusion of sterilization gas.
In addition,, judge whether the leakage and unexpected intrusion of sterilization gas,, can both reclaim at an easy rate on the position of indicator so gas detection section 35 preferably is configured in when sterilization processing finishes owing to be preferably in when carrying out each time sterilization processing.Therefore, in present embodiment 2, adopted it is configured in structure on the inner surface of the loam cake 31 that constitutes shell 26.Be configured under this locational situation, for example, comparing with the situation on the bottom that is configured in case 30, loam cake 31 when case 30 disassembles, just can reclaim indicator easily.
Then, the check valve 28 that is configured on the shell 26 is described.The same with embodiment 1, check valve 28 is to make the inner space of shell 26 roughly be varied to vacuum, and keeps the parts of the atmosphere of this substantial vacuum.Generally, indoor the sterilization gas introduction chamber after the sterilizer volume inside zone (that is, chamber in) of having put into endoscope (and sterilizing pretest pack for endoscope) is evacuated, carry out the sterilization processing of endoscope thus.Because check valve 28 has the function that gas is only passed through to the spatial direction in outside from the inside of shell 26, so have following function, the evacuation operation of in the process of sterilization processing, being carried out, gas in the shell 26 is discharged to space outerpace, thereby form the atmosphere of substantial vacuum, and after being evacuated, in the time of in sterilization gas is imported into chamber, by valve-off, make the inner space of the inner space of shell 26 and pipeline resettlement section 27 keep the atmosphere of substantial vacuum.
Fig. 5 is the sketch map of the structure of expression check valve 28.As shown in Figure 5, check valve 28 has following part: body shell 44 is formed with the through hole of the inner space that is communicated with space outerpace and shell 26 (case 30); Piston 45 is configured in the through hole that is formed on the body shell 44 with being free to slide, and has piston main body 45a; Spring members 46 applies elastic force to the direction (below among Fig. 5) near shell 26 (case 30) to piston 45; As the part of piston 45, be used to dispose the spring backstopping assembly 45b of spring members; And when valve closing, be used to make roughly keep gastight O-ring seals 47 between piston 45 and the body shell 44.
Piston main body 45a has: large diameter part is formed with the groove that disposes O-ring seals 47; And small diameter part, its external diameter is littler than large diameter part, on the end can with spring backstopping assembly 45b screw threads for fastening, and small diameter part around dispose spring members 46.Spring backstopping assembly 45b has formed screw in the central, and by this screw, spring backstopping assembly 45b screw threads for fastening is on the end of piston main body 45a.The active force that is configured in the small diameter part spring members 46 on every side of piston main body 45a is set at, the strength that check valve 28 can both be worked under any pressure.The through hole that forms on body shell 44 comprises with corresponding first space, position of the large diameter part of piston main body 45a with as second space of the part of configuration spring members 46.Internal diameter between first, second space forms, and the small diameter part of piston main body 45a can pass, and large diameter part can not pass.That is, spring members 46 is configured in second space, the state of being clamped by spring backstopping assembly 45b and body shell 44.Under externally spatial force value and the identical or higher situation of the pressure of the inner space of shell 26, piston 45 is by being subjected to the active force towards shell 26 1 sides by spring members 46, thereby as shown in Figure 5, the first spatial inclined plane that forms on body shell 44 closely contact with O-ring seals 37, blocks being communicated with between the inner space of space outerpace and shell 26.Usually, just be in the state (valve closing state) of this blocking-up.
On the other hand, before importing sterilization gas, carry out the evacuation operation in, to the space outerpace side shifting, remove the tight contact condition (valve open state) of the first spatial rake and O-ring seals 47 by means of piston.Fig. 6 is the sketch map of this state of expression.In the evacuation operation, externally in the space, by means of the effect of specified vacuum pump etc. gas is discharged to the outside, so the pressure in the space outerpace is lower than the pressure in the inner space of shell 26.Therefore, as the external force that acts on the piston 45, the pressure that is present in the gas in the inner space of shell 26 is dominant, piston 45 moves to outside direction in space (top among Fig. 6), the first spatial rake that forms on body shell 44 and the tight contact condition of O-ring seals 47 are disengaged, and the inner space of space outerpace and shell 26 is communicated with gap between the piston 45 by through hole.Owing to carry out evacuation with respect to space outerpace, so shell 26 gas inside are discharged to space outerpace by after the gap, the inner space of shell 26 roughly becomes the atmosphere of vacuum.
In addition, as mentioned above, when carrying out sterilization processing, after finishing the evacuation operation, just import sterilization gas with sterilizer.; because in this operation; the force value of space outerpace is bigger than the pressure (atmosphere of substantial vacuum) of the inner space of shell 26; so piston 45 just maintains the first spatial rake that is formed in the body shell 44 and O-ring seals 47 tight state of contact (promptly; state shown in Figure 5); space outerpace is not communicated with the inner space of shell 26, during the importing operation of sterilization gas, is still keeping in the interim substantial vacuum atmosphere that forms in the inner space of shell 26.
Then, the inner shell 33 that is housed in shell 26 inside is described.The same with the inner shell 3 among the embodiment 1, inner shell 33 is keeping indicator in inside, this indicator is used for judging as whether having been carried out reliable sterilization processing by the endoscope of germicide, and inner shell 33 is the parts that are used for importing to this indicator sterilization gas by first pipeline 38 and second pipeline 39.
Fig. 7 is the sketch map of the structure of expression inner shell 33.As shown in Figure 7, inner shell 33 has following each several part: the housing body 50 of accommodating indicator 49; Lid 51 forms on housing body 50 and can freely load and unload; The O-ring seals of seal casinghousing main body 50 and lid 51 airtightly roughly; And the connecting portion 52,53 that is used to be communicated with the inside of housing body 50 and first pipeline 38, second pipeline 39.Connecting portion 52,53 is fixed on the housing body 50 in gastight mode roughly.
Then, housing body 50 is described.Fig. 8 is the sketch map of the outward appearance of expression housing body 50.As shown in Figure 8, housing body 50 forms except being used to lid 51 is installed the part of ridge, also has to be used for O-ring seals that seals in gastight mode roughly and the retaining part that forms flat indicator 49.In addition, form ridge near, be formed with narrow slit 50a, indicator 49 can be inserted in the space in the housing body 50 by narrow slit 50a, or therefrom pulls out.
Then, maintaining part 34 is described.Maintaining part 34 is to be used for inner shell 33 is stably remained on parts in the shell 26, and as shown in Figure 4, it is fixed on the inner surface of the case 30 that constitutes shell 26, and has the function that keeps inner shell 33.
Fig. 9 is the sketch map of the structure of expression maintaining part 34.As shown in Figure 9, maintaining part 34 has such structure, that is, at the upper and lower that forms columnar maintaining part main body 34a, integrally formed fin 34b, 34c.On fin 34b,, on maintaining part main body 34a, fin 34b, 34c, be formed with suitable blow vent 34e respectively except being formed for inserting the housing insertion section 34d of inner shell 33.In addition, shown in the profile of the maintaining part 34 of Fig. 4, on the inner surface of housing insertion section 34d, be formed with and be used for localized protuberance.
The internal diameter that fin 34b, 34c form the size of external diameter and case 30 about equally.By means of this structure, maintaining part 34 seamlessly is configured in the case 30.In addition, maintaining part 34 is adhesively fixed in the case 30.
In addition, blow vent 34e is used for preventing when being configured in maintaining part 34 in the case 30, forms the opening of confined space in case 30.For example, form cylindrical shape owing to constitute the maintaining part main body 34a of maintaining part 34, so inside just exists the gap.Formed in this gap under the situation of confined space, promptly use check valve 28 to carry out exhaust work, air in the confined space can not be discharged, the result, can not allow pressure state homogenization in the test assembly, therefore in order to keep good connected state, on each position, form blow vent 34e with other area of space.
In addition, the height of maintaining part 34, and inner shell 33 is inserted insertion amount in the housing insertion section 34d etc. can determine arbitrarily.But, in present embodiment 2, as ideal example, pre-determine the height of maintaining part 34 and inner shell 33 is inserted insertion amount among the housing insertion section 34d etc., make the upper end of lid 51, be positioned on the position than the more close top of opening portion of case 30 as the structural element that remains on the inner shell 33 on the maintaining part 34.In addition, if at the inner face of housing insertion section 34d the location protuberance is set, assembling just is easy to.
Figure 10 represents a sketch map of the state that the loam cake 31 that constitutes shell 26 disassembles from case 30.As shown in figure 10, in present embodiment 2, the structure of maintaining part 34 and inner shell 33 is to determine like this, promptly, when loam cake 31 is disassembled, be housed in the case 30, as the upper end of the lid 51 of the structural element of inner shell 33 in the state that protrudes than the more close top of the opening portion of case 30.Adopt this structure, after sterilization processing finished, being housed in indicator 49 in the inner shell 33 when taking out, user can be held lid 51 at an easy rate, thereby can disassemble lid 51 at an easy rate.More than, the structure of embodiment 2 has been described, each several part fits together mutually roughly to keep gastight state, has only the loam cake 31 of shell 26 and the lid 51 of inner shell 33 to load and unload with respect to case 30 and housing body 50.
Then, the using method of the sterilizing pretest pack for endoscope of simple declaration present embodiment 2.The sterilizing pretest pack for endoscope of present embodiment 2, need in advance portion within it be provided for confirming as the chemistry of the bactericidal effect of the sterilizing unit of object or biology indicator 49.At first, threads turn loam cake 31 is unloaded it down from case 30, and then, the lid 52 of threads turn inner shell 33 is unloaded it down again.So the narrow slit 50a of inner shell reveals, indicator 49 is inserted among the narrow slit 50a.After inserting indicator 49 in the inner shell 33, lid 51 is installed on the housing body 50, loam cake 31 is installed on the case 30.At this moment, each housing and lid all remain on roughly under the airtight conditions, and each lid is become flexible because of the pressure of sterilizing unit changes by screw threads for fastening Cheng Buhui.Then, sterilizing pretest pack for endoscope and as being placed into together by the endoscope of germicide in the sterilizer of regulation, with endoscope same condition under, accept sterilization processing.Then, in the evacuation operation of carrying out as the preceding operation that imports sterilization gas, effect by means of above-mentioned check valve 28, make the inner space of shell 26 and the inner space of pipeline resettlement section 27, in particular, make inner shell 33 around and the atmosphere that becomes on every side vacuum of first pipeline 38 and second pipeline 39.Check valve 28 has according to pressure condition makes the inner space of shell 26 and the structure of external communications.Because the inner space of pipeline resettlement section 27 has the structure that the inner space by connecting portion 29 is communicated with the inner space of shell 26, so as mentioned above, the inside of sterilizing pretest pack for endoscope just becomes uniform substantial vacuum state.
Then, import sterilization gas.Sterilization gas flows in first pipeline 38, second pipeline 39 by gas introduction port 40a, 41a, through after these two pipelines, arrives inner shell 33.Owing to keeping indicator 49 in inner shell 33, the sterilization gas after arriving will act on indicator 49.In addition, in this operation, because check valve 28 has separated the inner space of space outerpace and shell 26,, make the atmosphere of above-mentioned inner space maintenance substantial vacuum so sterilization gas can not flow in the inner space of the inner space of shell 26 and pipeline resettlement section 27.
After this, the sterilizing pretest pack for endoscope of present embodiment 2 with as by the endoscope of germicide, is taken out from sterilizer, carry out the affirmation of bactericidal effect.That is, respectively the lid 51 of loam cake 31 that constitutes shell 26 and formation inner shell 33 is disassembled, take out the indicator 49 that is housed in the inner shell 33.Then, by confirming the sterilization situation of indicator 49, just can judge whether as having been carried out sufficient sterilization by the endoscope of germicide.In addition, the same with the affirmation of indicator 49, also will check the leakage whether sterilization gas is arranged in the gas detection section 35, and sterilization gas invades unexpectedly, and also will confirm when importing sterilization gas, wait the atmosphere that whether keeps substantial vacuum around the inner shell 33.
The advantage of present embodiment 2 then, is described.At first, the same with the situation of embodiment 1, because the sterilizing pretest pack for endoscope of present embodiment 2 is put into sterilizer with endoscope and is carried out sterilization processing, so needn't directly verify, just can judge whether endoscope sterilizes fully to endoscope inside.Promptly, the sterilizing pretest pack for endoscope of present embodiment 2, owing to have through first pipeline 38 and second pipeline 39 sterilization gas imported structure in the inner shell 33, and pipeline 38,39 have with as the same structure of formed pipeline on by the endoscope of germicide, so, sterilization gas arrives the condition of inner shell 33, and is basic identical with the condition that arrives the pipeline mid point that endoscope had.Therefore, with the roughly the same condition of the condition of the pipeline mid point that arrives endoscope under, sterilization gas arrives the indicator 49 that is configured in the inner shell 33, by confirming the reaction condition of indicator 49, just can judge correctly that endoscope (in particular, be the most difficult part that sterilizes, the i.e. mid point of ducts of endoscope) sterilization situation.
In addition, the same with the situation of embodiment 1, the structure of present embodiment 2 is when importing sterilization gas, by means of the effect of check valve 28, to make the atmosphere that keeps substantial vacuum on every side of inner shell 33.Like this, be housed in the temperature of the indicator 49 in the inner shell 33, just only change according to the sterilization gas that is imported through first pipeline 38 and second pipeline 39, thus can more correctly realize with the sterilization environment facies of the pipeline that in endoscope, forms with, perhaps stricter sterilization environment.
General sterilization processing is to be undertaken by being exposed in the sterilization gas atmosphere under the hot conditions of regulation, in order fully to carry out sterilization processing, and must be the temperature that is heated to regulation by germicide.Therefore, in the coefficient of overall heat transmission that is delivered to inner shell 33 from space outerpace, than being delivered to from space outerpace as by under the taller situation of the coefficient of overall heat transmission of the ducts of endoscope mid point of germicide, the indicator 49 that is configured in inner shell 33 inside just is in than in the also weak sterilization environment of pipeline mid point, might reduce the judgement precision to the sterilization conditions of endoscope.Particularly, because inner shell 33 will be accommodated indicator 49, so have to adopt the structure with surface area bigger than the pipeline of endoscope, under residual the situation of heat transfer substances such as gas, the probability that the coefficient of overall heat transmission is higher than the pipeline of endoscope is very big around inner shell 33.
For this reason, the same with embodiment 1, present embodiment 2 has adopted when importing sterilization gas, allows inner shell 33 keep the structure of substantial vacuum atmosphere on every side.As everyone knows, because the atmosphere of substantial vacuum has shown very superior heat-insulating property, so, from space outerpace directly (promptly, be not by means of the sterilization gas that has passed through first pipeline 38 and second pipeline 39) transmit the heat of coming in, almost can ignore.Therefore, the sterilizing pretest pack for endoscope of present embodiment 2 from the viewpoint of the coefficient of overall heat transmission, has the advantage that can realize the sterilization environment roughly the same or strict more with pipeline that endoscope has.
Also have, the sterilizing pretest pack for endoscope of present embodiment 2 has a plurality of pipelines is housed in structure in the independent pipeline resettlement section 27.Therefore, the sterilizing pretest pack for endoscope of present embodiment 2 also can be realized such as shown in Figure 3 simple surface structure, for the user, has easy to operate advantage.
In addition, in present embodiment 2, the structure of employing is, is housed in the independent pipeline resettlement section 27 corresponding to first pipeline 38 and second pipeline 39, when importing sterilization gas, keeps the substantial vacuum atmosphere around making first pipeline 38 and second pipeline 39.At this moment, when each pipeline is near each other,, might influence each other at heating surface.
For this reason, in present embodiment 2, adopted such structure: when importing sterilization gas, make first pipeline 38 and second pipeline, 39 both sides' the atmosphere that keeps substantial vacuum on every side, thereby prevent that generation is heat passage between first pipeline 38 and second pipeline 39 etc., make and can not transmit heat mutually between the pipeline.By adopting such structure, can make the sterilization environment in the sterilizing pretest pack for endoscope also stricter, thereby have the higher advantage of the degree of reliability that the sterilization situation is judged than the sterilization environment of endoscope.
Also have, the sterilizing pretest pack for endoscope in the present embodiment 2 has such structure: have the gas detection section 35 that is used to detect sterilization gas inflow shell 26 inner spaces.Can understand from above explanation, dispose the inside of the shell 26 of inner shell 33, when importing sterilization gas, need to keep the atmosphere of substantial vacuum.; for example under situation such as the air-tightness of shell 26 is not enough; in the operation of evacuation; effect by means of check valve 28; make the inside of shell 26 become the atmosphere of substantial vacuum; when importing sterilization gas, make the inner space of sterilization gas inflow shell 26 then, might destroy the atmosphere of substantial vacuum.Under the ruined situation of the atmosphere of substantial vacuum, owing to can not expect above-mentioned insulation effect again, thereby judge that by means of sterilizing pretest pack for endoscope the degree of reliability of the sterilization situation of endoscope has just reduced.Therefore, in present embodiment 2, in order to confirm whether have this sterilization gas to flow into and disposed gas detection section 35, under the situation of the inner space of having confirmed sterilization gas inflow shell 26 by gas detection section 35, utilize another test assembly to carry out countermeasures such as endoscope's sterilization processing once more.As a result, owing to the long-time situations such as producing deterioration of using, just in case under the situation about having problems on the structure of shell 26 etc., present embodiment 2 also has the advantage that can detect this unfavorable condition rapidly.
(variation 1)
Below, the variation 1 of embodiment 2 is described.The sterilizing pretest pack for endoscope of this variation 1, also has following mechanism, when importing sterilization gas, this mechanism can detect the inner space of shell 26 and pipeline resettlement section 27 (in other words, i.e. inner shell 33, first pipe, 38 and second pipeline 39 around) and whether keep the substantial vacuum atmosphere.
Figure 11 is the sketch map of this mechanism of expression and peripheral structure thereof.As shown in figure 11, on case 55 as the shell mechanism key element, except with the coupling part of loam cake 31, also formed the through hole that is communicated with space outerpace.Sterilizing pretest pack for endoscope in this variation 1 has following structure,, by the flexible thin 56 that is adhesively fixed in gastight mode roughly, covers this through hole that is.
Flexible thin 56 is as vacuum detecting portion, and its effect is to detect the atmosphere that whether has kept substantial vacuum in the case 55.Specifically, flexible thin 56 is to make by having bubble-tight softish lamellar parts, it blocks gas flow between the inner space of space outerpace and case 55 on the one hand, on the other hand, also have according to the magnitude relationship between the pressure of the inner space of the pressure of space outerpace and case 55 and the character of easy deformation.Flexible thin 56 utilizes this character, and whether the inner space that just can detect case 55 has kept the atmosphere of substantial vacuum.
Figure 12 is illustrated in after sterilization processing finishes, the sketch map of the state that the sterilizing pretest pack for endoscope of this variation 1 is taken out from sterilizer.Under the situation that each element of sterilizing pretest pack for endoscope works orderly, effect by means of above-mentioned check valve 28, make the inner space of case 55 keep the atmosphere of substantial vacuum, only otherwise disassemble, just can keep the atmosphere of this substantial vacuum with the case 55 common loam cakes 31 that constitute shells.Therefore, when sterilizing pretest pack for endoscope is taken out, be placed on condition of normal pressure following time from sterilizer, the pressure of space outerpace is just than the pressure height of case 55 inner spaces, so, seem that from space outerpace flexible thin 56 just is deformed into recessed shape along with this pressure differential.Therefore, user can judge whether to have kept the substantial vacuum atmosphere at an easy rate according to the affirmation to flexible thin 56 shapes, has the advantage that can judge whether sterilizing pretest pack for endoscope has been carried out suitable sterilization processing operation at an easy rate.
(variation 2)
The variation 2 of embodiment 2 then, is described.The sterilizing pretest pack for endoscope of this variation 2 also has the structure that pipeline resettlement section 27 is held in spiral helicine keeper.Figure 13 is the sketch map of outward appearance of the sterilizing pretest pack for endoscope of expression this variation 2.As shown in figure 13, in this variation 2, also have the face shaping of pipeline resettlement section 27 is held in spiral helicine keeper 58.
