Description

Decontaminating apparatus

Technical field

The present invention relates to be suitable for the decontaminating apparatus of the armarium sterilizations such as endoscope, in more detail, relate to the decontaminating apparatus of the function with the bottle of opening the concentrated solution of accommodating disinfectant solution.

Background technology

In the endoceliac inspection of organism or operation, use widely endoscope.Endoscope has: inserting paragraph, its insertosome intracavity; Lever piece, it regulates the direction of the front end of this inserting paragraph.Inserting paragraph is and has flexual bar-shapedly, and has the electronics shoot part to taking in body cavity and allows treatment tool insert the logical various passages such as pliers passage.Body fluid or foul have adhered in the outer surface of inserting paragraph and each passage in the endoscope use finishing.The pathogen containing in body fluid or foul or virus are to cause the inner reason infecting, and the endoscope after therefore using need to clean with cleaning and sterilizing device for endoscope, sterilize.

Described cleaning and sterilizing device for endoscope has the rinse bath of cleaning endoscope and accommodates the disinfectant solution tank of disinfectant solution, and automatically carries out the various operations such as matting, disinfecting steps.In matting, by water, in water, add the cleanout fluid such as detergent and to the endoscope in rinse bath, blow body fluid or the foul adhering in attached flushing outer surface and each passage.In disinfecting steps, from disinfectant solution tank, the disinfectant solution of ormal weight is supplied with in rinse bath.Endoscope is immersed in this disinfectant solution, removes bacterium or the virus in matting, do not removed, and eliminate pathogenicity.When matting finishes, in order to re-use disinfectant solution, make disinfectant solution return in disinfectant solution tank.

In disinfectant solution, for example use the high level disinfectant of glutaraldehyde, o-phthalaldehyde(OPA), peracetic acid etc.Use glutaraldehyde in the past, but use widely the peracetic acid that Disinfection Effect is high and little to the harmful effect of human body now.

The concentrated solutions such as peracetic acid (stock solution) add diluent for example water, be modulated into the disinfectant solution of normal concentration.For example, in the concentrated solution of peracetic acid, because peracetic acid concentration is 6%, and contain more than 10% hydrogen peroxide, be therefore taken as noxious substance and process.This concentrated solution has very strong foul smell, therefore, in taking in the plastic bottle of concentrated solution, conventionally with seal members such as tinfoil, plastic sheetings, seals this mouth cylindrical part, and covers bottle cap.

If the stink from leakage of concentrated solution in the making of disinfectant solution, working environment worsens.In order to prevent this stink from leakage, the bottle installation portion of the oral area of bottle and cleaning and sterilizing device for endoscope carries out airtight and liquid-tight ground combination.Under this state, cut seal member.The concentrated solution flowing out from bottle injects road direction disinfectant solution tank via concentrated solution and supplies with.Although the foul smell of concentrated solution not to cleaning and sterilizing device for endoscope external leakage, can produce the seal member of cutting and wander unfavorable condition in disinfectant solution tank or seal member and stop up the unfavorable condition that concentrated solution injects road etc.

In order to prevent described unfavorable condition, in the cleaning and sterilizing device for endoscope described in TOHKEMY 2006-230493 communique for example, there is a bottle cap cylindraceous the oral area of bottle is chimeric.The tabular occlusive part that can cut is formed on this bottle cap, and seals bottle cap midway.And, at the bottle installation portion that is arranged at disinfectant solution tank, be formed with blade, expansion face, dodge portion, press section.If bottle is inserted to bottle installation portion, first blade forms otch in a part for occlusive part.Next, expansion face is pressed at leisure the both sides of otch and it is broken.This part of breaking little by little expands according to the amount of being pressed into of bottle.Because the portion that dodges that extends to expansion face is not according to pressing off piston part, the part of therefore breaking does not extend to the complete cycle of occlusive part.Finally, press occlusive part press section to bottle inner side, and by the portion of dodging, occlusive part is tilted roughly about 45 degree from residual linking portion (part being connected with bottle cap).Therefore according to this structure, owing to can not cutting occlusive part from bottle, do not produce occlusive part and flow in disinfectant solution tank, or stop up the unfavorable condition that concentrated solution injects road etc.

When changing disinfectant solution, from bottle installation portion, take off empty bottle, the foul smell that still now remains in the concentrated solution in bottle and in bottle installation portion leaks to outside.For anti-, plant here situation, in the device of for example Japanese kokai publication hei 11-137506 communique, record the method with nozzle cleaning bottle.Overhead guard at rinse bath is provided with a bottle adapter, and at this bottle of adapter, plug projection is installed out.At bottle adapter, install bottle oral area during, seal member is opened plug by bottle and is opened hole by projection, and the concentrated solution in bottle is wandered to rinse bath.After injecting disinfectant solution, the concentrated solution in rinse bath is shifted to disinfectant solution tank.Next, to rinse bath, supply feedwater (cleanout fluid), to cleaning in rinse bath.Meanwhile, utilize and be configured in the substantial middle position of rinse bath, and carry out washer bottle for cleaning the nozzle of the inner surface of overhead guard.After washer bottle, from bottle adapter, take off bottle, then discharge the water in rinse bath.In this Unexamined Patent 11-137506 communique, also record to open to fill at bottle and add nozzle function by projection.

In the cleaning and sterilizing device for endoscope that TOHKEMY 2006-230493 communique is recorded, the stink from leakage in order to prevent from taking off bottle, the bottle cleaning technique that preferably adopts Japanese kokai publication hei 11-137506 communique to record.But, in the device of recording at TOHKEMY 2006-230493 communique, due to the cleanout fluid of the nozzle ejection in rinse bath and in the tilted occlusive part collision of bottle, therefore can not arrive the depths of washer bottle.And, from the cleanout fluid of nozzle ejection and washer bottle inside, to the mobile rework solution of oral area, collide, therefore can not carry out fully the cleaning in bottle.

When bottle adapter arranges nozzle dual-purpose projection, concentrated solution or cleanout fluid in bottle are discharged by the path in nozzle projection.Therefore,, in the cleaning of bottle, owing to must being passed in rework solution concentrated in oral area from the cleanout fluid of nozzle projection ejection, therefore washer bottle is inner fully.And, the disinfectant solution in bottle, to after discharging in rinse bath, need to be connected the pipe of supplying with cleanout fluid with nozzle dual-purpose projection.For this reason, need to arrange the charging crane of pipe in rinse bath, it is complicated that structure becomes.

In addition, in TOHKEMY 2006-230493 communique, if insert bottle at bottle installation portion,, when occlusive part breaks, a large amount of concentrated solutions inject with sudden force, the danger that therefore has concentrated solution to overflow from bottle installation portion.And, even if concentrated solution does not reach the degree of overflowing, concentrated solution also with blade or blade near expansion face collision and rebound in a large number and cause liquid stream disorderly, therefore can not make concentrated solution flow into smoothly disinfectant solution tank.

Press section 110c is present in the facial 110b of expansion and the border of dodging the 110d of portion.Press section 110c and occlusive part 39 butts described in when the insertion amount of bottle unit 38 arrives certain value.If further insert a bottle unit 38, as shown in figure 14, in the time of bending linking portion 39, occlusive part 39c is upwards pressed into the inner side of first bottle 39.Thus, be formed for discharging the liquid outlet of the concentrated solution in first bottle 39.In addition, in oral area 39b, its internal diameter is for example 34mm, and linking portion 39e has the length (34 °～36 ° of arc chord angles) of about 10mm.

At bottle, open in piston part 110, on side face, be provided with integratedly bottle washer jet 112 within it.Bottle washer jet 112 radially be for example centered close to the position of 3 that bottle is opened piston part 110.The front end of bottle washer jet 112 for prevent in bottle unit 38 while inserting with occlusive part 39c butt, and be positioned at than expanding the facial 110b position of (disinfectant solution tank 87 sides) in the inner part.At bottle washer jet 112, be connected with from the cleanout fluid stream 113 (with reference to Fig. 4) for water route 76 branches.

With reference to Fig. 6, illustrate that occlusive part 39c, linking portion 39e, bottle washer jet 112 open the position relationship in the radial section of piston part 110 at bottle.Linking portion 39e center (positions of 10: 30) be positioned at respect to the plumb line L1 that opens the radial section center of piston part 110 by bottle become-45 ° (clockwise for+, be counterclockwise-) on the straight line L2 at angle.Bottle washer jet 112 center (positions of 3) is positioned at respect to plumb line L1 to become on the straight line at+90 ° of angles.Linking portion 39e is with bottle washer jet 112 when this position relationship, and the extended line of bottle washer jet 112, as shown in shade, does not intersect with crooked occlusive part 39c.Thus, from the bottle cleanout fluid of bottle washer jet 112 ejections, do not collide with the occlusive part 39c of bending.

In bottle resettlement section 37, be provided with the second bottle of installation portion (without diagram) for accepting second bottle 40.Second bottle of installation portion has and first bottle of structure that installation portion 108 is identical.At second bottle of installation portion, be connected with concentrated solution and inject buffer agent injection road side by side, road 109.By buffer agent, inject the interior supply of road direction disinfectant solution tank 87 with first bottle of 39 buffer agent of opening in the same manner in second bottle 40, the second bottles 40.And, at second bottle of installation portion, being also provided with washer jet (without diagram), spray bottle cleanout fluid also cleans second bottle of 40 inside.Now, bottle cleanout fluid does not collide with the occlusive part (without diagram) of bending.

In Fig. 4, in bottle resettlement section 37, be provided with the bottle sensor 116 that detects bottle unit 38.When being pressed into first bottle of installation portion 108 and second bottle of installation portion by first bottle 39 and second bottles 40, bottle sensor 116 detects bottle unit 38.

Cleanout fluid stream 113 is from diluent stream 117 branches.At diluent stream 117, from confession water route 76 sides, be disposed with electronic three-way valve 114 and the effusion meter 115 of electromagnetic valve 111, switching stream.Inflow entrance at electronic three-way valve 114 is connected with diluent stream 117, at a flow export, is connected with diluent stream 117, at another flow export, is connected with cleanout fluid stream 113.Diluent stream 117 is directly connected with disinfectant solution tank 87.By switching electronic three-way valve 114, select to supply water or supply water to cleanout fluid stream 113 to diluent stream 117.

Effusion meter 115 is measured the flow of the bottle cleanout fluid (water) of supplying with to cleanout fluid stream 113.The data of the flow based on from effusion meter 115 are controlled WP80, and adjust the supply pressure to the water for water route 76.Bottle cleanout fluid from from bottle washer jet 112 to first bottle of 39 interior injection cleans first bottle of 39 inside.CPU122 (with reference to Fig. 7) measures bottle scavenging period.When the integrated flow of the bottle cleanout fluid of being supplied with to cleanout fluid stream 113 by this scavenging period judgement has reached setting, make electronic three-way valve 114 work.This electronic three-way valve 114 switches the stream of diluent (water) from cleanout fluid stream 113 side direction diluent stream 117 sides, and by diluent stream 117, diluent is injected in disinfectant solution tank 87.Switch after electronic three-way valve 114 WP80 high speed rotating, the hydraulic pressure of raising diluent.Thus, the quantity delivered of diluent increases, can be at short notice to the diluent of the interior supply ormal weight of disinfectant solution tank 87.

In disinfectant solution tank 87, be provided with the concentrated solution sensor 118 and the disinfectant solution sensor 119 that detect liquid level and connect.Concentrated solution sensor 118 and disinfectant solution sensor 119 are for example arranged on from the outside of disinfectant solution tank 87 hole that is formed at disinfectant solution tank 87.The sealing member that prevents that disinfectant solution 86 from leaking is installed between the hole of disinfectant solution tank 87 and concentrated solution sensor 118 and disinfectant solution sensor 119.In the seal, use has the silicone rubber (VMQ) of resistance etc. to peracetic acid.

Concentrated solution sensor 118 detects whether correctly carry out bottle Kaifeng, whether to disinfectant solution tank 87, supplies with concentrated solution and buffer agent.Disinfectant solution sensor 119 detects the disinfectant solution of mixed diluting liquid in concentrated solution and buffer agent and whether arrives ormal weight.At this, because concentrated solution and buffer agent are supplied with from bottle, so capacity is for certain is specifically worth.Therefore, disinfectant solution sensor 119 detects the diluent of whether only supplying with aequum for the disinfectant solution 86 of modulation specifications concentration.In addition, in disinfectant solution tank 87, not only from the diluent of diluent stream 117, and the bottle cleanout fluid cleaning first bottle 39 is also supplied with as diluent.Therefore, disinfectant solution sensor 119 detects the liquid level of the disinfectant solution that concentrated solutions, buffer agent, diluent and bottle cleanout fluid mixed.

As shown in Figure 7, install 28 and have: CPU122, its centralized Control each several part ROM123, its storage control program or various data; RAM124, it is for temporarily storing input data and control sequence.At CPU122, be connected with the sensors such as liquid level sensor 66, temperature sensor 72, effusion meter 115, bottle sensor 116, concentrated solution sensor 118, disinfectant solution sensor 119.And, CPU122 be also connected with drive display floater lcd driver 125, drive the valve actuator 126 of each electromagnetic valve, drive respectively the motor driver 127 of electronic three-way valve 75,114 etc.Drive the WP driver 128 of each WP, the heater driver 129 of driving rubber heater 71 etc. are also connected with CPU122.

Device 28 is carried out a plurality of action patterns such as cleaning and sterilizing pattern, disinfectant solution modulating mode, disinfectant solution discharge pattern.Each pattern is selected by the operation of guidance panel 33.Next, with reference to Fig. 8 and Fig. 9, the disinfectant solution modulating mode at the new disinfectant solution 86 of disinfectant solution tank 87 internal modulations is described.

If the operation by guidance panel 33 is set to disinfectant solution modulating mode (S1), whether the signal of CPU122 based on from concentrated solution sensor 118 and disinfectant solution sensor 119, have disinfectant solution 86 (S2) in confirmation disinfectant solution tank 87.The disinfectant solution 86 that reaches replacing period is stored in disinfectant solution tank 87 when interior (S2 is yes), and CPU122 opens electromagnetic valve 92 and discharges the interior used disinfectant solution 86 of disinfectant solution tank 87 (S3).In addition, preferably, after discharging disinfectant solution 86 by the diluent of ormal weight to the interior supply of disinfectant solution tank 87, cleaning and sterilizing flow container 87 inside.Open electromagnetic valve 92 and discharge the diluent that this cleaning is used.

While there is no disinfectant solution 86 in disinfectant solution tank 87 (S2 is no), or after discharging old disinfectant solution 86 (S3), CPU122 represents load the information of new bottle unit 38 at display floater 34.

Next, open door 36, bottle unit 38 is seated in to bottle incorporating section 37 (S4).Now, as shown in Fig. 9 (A), store the bottle unit 38 of concentrated solution 132 and buffer agent under the state with oral area 39b mode ramp down downward, from oral area 39b side, enter in bottle resettlement section 37.This bottle of unit 38 is loaded on bearing-surface 107.

As shown in Fig. 9 (B), bottle unit 38 is slided on bearing-surface 107, and oral area 39b is pressed in first bottle of installation portion 108.If be pressed into bottle unit 38, first blade 110a forms otch at occlusive part 39c.Next, expanding facial 110b breaks occlusive part 39c to extend the mode of otch.The part expansion at leisure of breaking of inaccessible wall 39c, but by dodging the effect of the 110d of portion and press section 110c, occlusive part 39c does not fully depart from from oral area 39b, and remains with linking portion 39e.Press section 110 is the inner side bending to first bottle 39 by occlusive part 39c from this linking portion 39e, and and oral area 39b between form flow export.Now, in the periphery of oral area 39b, so that airtight and liquid-tight mode is chimeric, have first bottle of installation portion 108, therefore, the foul smell of concentrated solution 132 does not leak from first bottle 39.In addition, second bottle 40 also airtightly and liquid-tight is in the same manner embedded in second bottle of installation portion with first bottle 39, and is opened.

Concentrated solution 132 in bottle unit 38 and buffer agent inject road 109 by concentrated solution and buffer agent injects the 87 interior inflows of road direction disinfectant solution tank.Concentrated solution sensor 118 detects liquid level the connection (S5 is yes) that concentrated solutions 132 have mixed with buffer agent.

Bottle sensor 116 detects and is housed in the bottle unit 38 of bottle resettlement section 37 and connects.And CPU122 counted the elapsed time of connecting from bottle sensor 116.Therefore, correctly open first bottle 39 and second bottles 40, and when correctly concentrated solution 132 and buffer agent are supplied with to disinfectant solution tank 87, from bottle sensor 116, connect and start concentrated solution sensor 118 in official hour and connect.On the other hand, (S5 is no) during concentrated solution sensor 118 access failure at the appointed time, the bottle unit 38 that the amount of accommodating of empty bottle unit 38 or concentrated solution 132 etc. of can arranging is few etc.And during from bottle installation portion generation leak of liquid, contracting liquid sensor 118 is also disconnected.Now, for example, carry out demonstrating at display floater 34 fault processing (S6) of error message etc.

As shown in Fig. 9 (C), CPU122 opens electromagnetic valve 78,111 according to the connection signal of concentrated solution sensor 118.And, electronic three-way valve 114 is switched to cleanout fluid stream 113 sides.Water mobile in for water route 76 and cleanout fluid stream 113 is as bottle cleanout fluid, from bottle washer jet 112 to first bottle of 39 interior injection (S7).Thus, by bottle cleanout fluid, rinse the concentrated solution 132 remaining in first bottle 39.Moreover in disinfectant solution modulating mode, electronic three-way valve 75 switches to connect the mode on feed flow road 74 and the first circulation road 103, so water does not flow in rinse bath 31.

Effusion meter 115 is measured at the flow of the interior mobile bottle cleanout fluid (water) of cleanout fluid stream 113 and is transmitted data to CPU122.Whether CPU122 monitors (S8) to this flow in prescribed limit.For example, this scope is 5～6 liters/min.If flow departs from prescribed limit (S8 is no), CPU122 controls the supply pressure of the water being produced by WP80 by WP driver 128, and flow is closed in prescribed limit (S9).In addition, the scope of suitable flow is according to the size of first bottle 39, the position of nozzle 112, the angle of inclination of bearing-surface 107 etc. and difference.

As shown in Figure 6, the bottle cleanout fluid spraying from bottle washer jet 112, cleaning first bottle of 39 inside, injects road 109 as rework solution 136 at concentrated solution and flows to disinfectant solution tank 87.Bottle washer jet 112 is positioned at than the high position of the liquid level of this rework solution 136 (water level).Like this, by suitably controlling the flow of rework solution 136, from bottle cleanout fluid and the rework solution 136 of bottle washer jet 112, do not collide.Therefore, can make bottle cleanout fluid arrive reliably the inside of first bottle 39, and can effectively clean first bottle 39.Moreover, in Fig. 6, describe linking portion 39e occlusive part 39c in addition and also contact with oral area 39b, but in fact, beyond linking portion 39e, do not contact with oral area 39b.Therefore,, when not considering the position of bottle washer jet 112, the water potential of rework solution 136 gets at the height at the edge that reaches linking portion 39e.In addition, the dash area of Fig. 6 represents the position of the occlusive part 39c of bending.

Inaccessible wall 39c, to be positioned at centered by the linking portion 39e of direction of 10: 30, stops up bottle and opens a part radially for piston part 110, but this part is non-intersect with the extended line of bottle washer jet 112 centered by the direction of 3.Like this, preferably, with occlusive part 39c, bottle washer jet 112, rework solution 136 separately hands-off mode locate linking portion 39e and bottle washer jet 112.

If cleaned, proceed to the stipulated time (S10 is yes), CPU122 drive motor device 127, and electronic three-way valve 114 is switched to diluent stream 117 sides (S11) from cleanout fluid stream 113 sides.This stipulated time is for example 20 seconds.Thus, from bottle washer jet 112 bottle cleanout fluid (water) ejection stop, but diluent (water) is from diluent stream 117 to the interior injection of disinfectant solution tank 87.With in bottle cleans, compare, in the dilution of concentrated solution, CPU122 improves the supply pressure (S12) of the water being produced by WP80 by WP driver 128.For example,, so that the mode that the flow of the diluent by diluent stream 117 is 10～12 liters/min is controlled the supply pressure of the diluent being produced by WP80.Thus, and omit diluent stream 117, the situation of only using bottle cleanout fluid from bottle washer jet 112 to dilute concentrated solution 132 is compared, and can dilute at short notice concentrated solution 132.In addition as the opportunity of switching electronic three-way valve 114, except the moment of CPU122 timing stipulated time, it can be also the moment that effusion meter 115 is measured the integrated flow of regulation.

By concentrated solution, inject road 109 to bottle cleanout fluid and the diluted concentrated solution 132 from diluent stream 117 to disinfectant solution tank 87 interior injections of disinfectant solution tank 87 interior inflows and modulate disinfectant solution 86.If the liquid level of disinfectant solution 86 reaches disinfectant solution sensor 119, disinfectant solution sensor 119 is connected (S13 is yes).CPU122, according to the connection signal of disinfectant solution sensor 119, by valve actuator 126 shut electromagnetic valves 78,111, and stops supplying with diluent (S14).Thus, the concentration that is regulation in interior disinfectant solution 86 dilutions of disinfectant solution tank 87.For example, concentrated solution 132 dilutions of peracetic acid 6% are for about 20 times.Like this, the disinfectant solution 86 of modulation is used in disinfecting steps.

In the cleaning of endoscope 10, sterilization, carry out matting, washing procedure, disinfecting steps, washing procedure, drying process etc.In matting, after supplying with, rinse bath 31 add the detergent in detergent tank 46 to make cleanout fluid in water.Make this cleanout fluid in rinse bath 31 internal recycle, cleanout fluid is attached to the appearance top blast of endoscope 10, and at the interior mobile cleanout fluid of each passage 15～17.If cleaned, proceed to the stipulated time, from rinse bath 31, discharge cleanout fluid, and carry out waste treatment.

After matting, to rinse bath 31, supply feedwater, and wash out the cleanout fluid that is attached to endoscope 10.If this washing procedure finishes, the washings in rinse bath 31 are carried out to waste treatment.

After washing procedure, start disinfecting steps.In this disinfecting steps, CPU122 drives WP88 and attracts the disinfectant solution 86 in disinfectant solution tank 87, and to rinse bath 31, supplies with the disinfectant solution 86 of ormal weight.Disinfectant solution 86 is heated by rubber heater 71.Disinfectant solution 86 is at each passage 15～17 internal recycle of rinse bath 31Ji endoscope 10, and removes pathogen or the virus not rinsing out in matting, and eliminates pathogenicity.After disinfecting steps finishes, disinfectant solution 86 returns in disinfectant solution tank 87 by waste liquid road 94,96, during maintaining Disinfection Effect, is reused.

After disinfecting steps, rush the washing procedure of the disinfectant solution 86 that falls to being attached to endoscope 10.After this washing procedure, carry out drying process.In this drying process, first in each passage 15～17 of endoscope 10, supply gas, ethanol next flows in each passage.After drying process, open overhead guard 49, from rinse bath 31, take out endoscope 10.

Because bottle washer jet 112 is arranged on bottle, open in piston part 110, and configure in the mode that the occlusive part 39c of bottle cleanout fluid and bending does not collide, so can clean reliably the inside of first bottle 39.And, because bottle washer jet 112 is positioned at the position higher than the water level of the rework solution of bottle cleanout fluid 136, therefore can when cleaning first bottle of 39 inside, smoothly rework solution 136 be turned back in disinfectant solution tank 87.And because bottle washer jet 112 enters in oral area 39b, therefore the pressure of bottle cleanout fluid raises, cleaning performance is good.

Due to so that the mode of spray volume in prescribed limit controlled the driving of WP80, therefore can suitably keep the water level of rework solution 136.Like this, can prevent reliably bottle cleanout fluid and rework solution 136 collisions.

Moreover, cleanout fluid stream 113 is from diluent stream 117 branches, when the spray volume of bottle cleanout fluid reaches ormal weight, electronic three-way valve 114 switches to diluent stream 117 by stream from cleanout fluid stream 113, therefore can be when bottle clean and change the quantity delivered etc. of water during dilution, thus carry out simply trickle control.And, in diluent stream 117, owing to WP80 being configured in in front of the branch point of cleanout fluid stream 113, therefore can supply with bottle cleanout fluid and diluent both sides by enough WP.

In said embodiment, the 110d of the portion that dodges that concentrated solution is injected to road 109 is configured in the position of 10: 30, and bottle washer jet 112 is arranged on to the position of 3 that concentrated solution injects road 109.Therefore, linking portion 39e center (positions of 10: 30) is positioned on the straight line that plumb line with respect to the radial section center by oral area 39b becomes-45 °, and bottle washer jet 112 center (positions of 3) is positioned on the straight line that plumb line with respect to the radial section center by oral area 39b becomes+90 °.But, in dodging the configuration of the 110d of portion and bottle washer jet 112, as long as the extended line of bottle washer jet 112 does not intersect with the bottle rework solution 136 of cleanout fluid and the occlusive part 39c of bending state, just can configure arbitrarily.

When preventing described intersection, guarantee the flow of rework solution 136 to a certain degree, preferably, linking portion 39e center for roughly becoming with respect to the plumb line at the radial section center by oral area 39b ± scope that two lines of 90 ° surround in, and, outside the scope that two lines that the angle that bottle washer jet 112 center becomes for the straight line with respect to the radial section center by oral area 39b and linking portion 39e is roughly ± 45 ° surround.

For example, linking portion 39e be centered close on the roughly become+line of 90 ° or-90 ° of plumb line with respect to the radial section center by oral area 39b time, bottle washer jet 112 center is outside the scope of two lines encirclements of angle that becomes roughly-45 ° and roughly-135 ° with respect to plumb line.This means can be by the center configuration of bottle washer jet 112 on plumb line.In addition, even linking portion 39e center is taken at respect to the plumb line at the radial section center by oral area 39b roughly on the in 90 ° or line of-90 °, the water level of the rework solution 136 of bottle cleanout fluid also can rise to the height at the edge of linking portion 39e, therefore can spray the bottle cleanout fluid of sufficient flow.

Moreover preferably, linking portion 39e is centered close to respect on the roughly become+line of 45 ° of plumb line time, bottle washer jet 112 center be to become in the scope of two lines encirclements of roughly-45 ° and roughly-90 ° with respect to plumb line.And linking portion 39e is centered close to while roughly becoming on the line of-45 ° with respect to plumb line, bottle washer jet 112 center be to become in the scope of two lines encirclements of roughly+45 ° and roughly+90 ° with respect to plumb line.

In said embodiment, a bottle washer jet 112 is arranged on to the position of 3 that bottle is opened piston part 110, but also plural bottle washer jet can be arranged on to bottle, opens piston part 110.For example, as shown in figure 10, linking portion 39e center is the position of 0, and is separately positioned on than two little bottle washer jet 152a of bottle washer jet 112 diameters and 152b and the position of 9 that bottle is opened piston part 110 at 3.; become 0 position linking portion 39e be centered close to the top (L1=L2) of plumb line L1 of opening the radial section center of piston part 110 by bottle, the center of bottle washer jet 152a and 152b the position of 9 (3 and) are positioned at respect to plumb line L1 to become on the straight line of+90 ° and-90 °.

According to which, by using two nozzles, even if dwindle each nozzle diameter, also can spray the nozzle cleaning liquid of ormal weight.Therefore, the overhang of radially center side from nozzle to bottle that open piston part 110 due to is little, even if therefore linking portion 39e is configured in to the position of 0, the occlusive part 39c of bending does not intersect with the extended line of bottle washer jet 152a and 152b yet.According to this example, open in piston part take the existing bottle that linking portion 39e breaks as the mode of the position of 0, bottle washer jet 152a and 152b are only set just passable, so favourable at design aspect.And, owing to using two bottle washer jets, therefore washer bottle efficiently.

Moreover, make linking portion 39e be centered close to the position of 0 time, needn't leave no choice but use two bottle washer jets, and the position of bottle washer jet can not be also and position at 3 at 9.But, preferably, in the scope of two lines that the angle that the center configuration of nozzle becomes at the plumb line at the radial section center with by oral area 39b is roughly+45 ° and+90 °, or be configured in the scope of two lines of roughly-45 ° and-90 °.

In addition, in said embodiment, the bottle washer jet of cross section toroidal is arranged on to concentrated solution integratedly and injects road 109, but also can arrange on split ground.And the cross sectional shape of bottle washer jet can not be also circular.For example, as shown in figure 11, also can bottle washer jet 162 be set the mode centered by bottle is opened the position of 1: 30 of piston part 110, wherein said bottle washer jet 162 has the ejiction opening of slit-shaped of opening the radial section curve of piston part 110 along bottle.In this embodiment, the center of linking portion 39e (positions of 10: 30) is positioned at respect to the plumb line L1 that opens the radial section center of piston part 110 by bottle to become on the straight line of-45 °, and the center (positions of 1: 30) of bottle washer jet 112 is positioned at respect to L1 to become on the straight line of+45 °.

Concentrated solution inject road 109 radially, because the width of bottle washer jet 162 is little, therefore compare for the situation of circular bottle washer jet 112 with using cross section, even bottle washer jet 162 is configured in to high position (more approaching the position of 0), the ejiction opening of described slit-shaped is not met with the occlusive part 39c of bending yet.Therefore, compare for the situation of circular bottle washer jet 112 with using cross section, the liquid level (water level) of rework solution that injects the radial section on road 109 can be brought up to the height at the edge of linking portion 39e at concentrated solution.Like this, can make the flow of the bottle cleanout fluid that the flow-rate ratio of the bottle cleanout fluid supplied with to bottle washer jet 162 supplies with to bottle washer jet 112 many, therefore, be improved the cleaning pressure of first bottle 39, and can modulate at short notice the advantage of disinfectant solution 86.

(the second embodiment)

Next, with reference to Figure 12 and Figure 13, illustrate at bottle and open the embodiment that piston part forms discharge opeing path.From bottle unit, 38 sides are observed bottle and are opened piston part 110, by bottle, open piston part 110 radial section center plumb line L1 above while being at 0, the center of discharge opeing path 110e is set to become the mode of the position of 6.In addition, bottle is opened piston part 110 except discharge opeing path 110e is set, is identical structure with the example shown in Fig. 5 and Fig. 6, therefore identical structure division is only added to label, and the description thereof will be omitted.And Figure 12, Figure 13 are identical with Fig. 5 and Fig. 6, represent bottle cleaning state.

Discharge opeing path 110e injects to concentrated solution the path that discharge on road 109 by concentrated solution for open the outer circumferential side of piston part 110 from bottle, and with the cross section toroidal in interior week of opening piston part 110 than bottle more to the outstanding mode of radially inner side, make bottle open the side face depression of piston part 110, thereby open between the outer peripheral face of piston part 110 and the inner peripheral surface on concentrated solution injection road 109 and form path at bottle.Discharge opeing path 110e produces otch mode not hinder blade 110a is positioned at the horizontal of blade 110a, and the entrance of discharge opeing path 110e is positioned at the position retreating a little than the facial 110b of expansion.The center of blade 110a (positions of 4: 30) is positioned at respect to the plumb line L1 that opens the radial section center of piston part 110 by bottle to become on the straight line L2 of+135 °.

If blade 110a forms otch at occlusive part 39c, the concentrated solution 132 spilling from otch towards at bottle, open piston part 110 radially foot (positions of 6).As shown in figure 14, due to discharge opeing path, 110e is positioned at the position of 6, therefore can avoid concentrated solution 132 and bottle to open the collision of piston part 110, and concentrated solution 132 enters in concentrated solution injection road 109 by discharge opeing path 110e.Because concentrated solution 132 flows into bottle quickly, do not open in piston part 110, therefore do not have concentrated solution 132 to open from bottle the danger that overflow piston part 110.And owing to can preventing opening rebounding of concentrated solution 132 that the collision of piston part 110 causes by concentrated solution 132 and bottle, so liquid stream is not disorderly, and can make smoothly concentrated solution 132 to the interior inflow of disinfectant solution tank 87.And, can make the residual liquid amount minimizing in bottle measure accordingly with the wall thickness amount that bottle is opened piston part 110.In addition, the buffer agent in second bottle 40 is also identical.

In said embodiment, the bottle that is centered close to of blade 110a is opened the position of 4: 30 of piston part 110, and discharge opeing path 110e be centered close to the position of 6 that bottle is opened piston part 110.Therefore, discharge opeing path 110e is positioned on the plumb line by the radial section center of oral area 39b, and blade 110a is positioned at respect to plumb line to become on the straight line at+135 ° of angles.But the position of blade 110a and discharge opeing path 110e is not limited to this.

For example, as shown in figure 15, also can be, the position of 5 of the Wei Pingkai piston part, center 110 of blade 110a (becoming with respect to plumb line L1 on the straight line at+150 ° of angles), and the position of 6 thirty of the Wei Pingkai piston part, center 110 of discharge opeing path 110e (with respect to plumb line L1, becoming on the straight line at-165 ° of angles).Like this, can make blade 110a approach the position of 6.In the situation that blade 110a is positioned at the position that approaches plumb line L1, when occlusive part 39c is broken, the highest position of the impetus of concentrated solution 132 is positions of 6.In described example, a part of discharge opeing path 110e is positioned at the position of 6 that bottle is opened piston part 110.Like this, if blade 110a be positioned at discharge opeing path 110e near, just can open the position that discharge opeing path 110e is changed in the design of piston part 110 according to bottle.

But, the viewpoint of the impetus of the concentrated solution from weaken the breaking of occlusive part 39c by discharge opeing path after, preferably, the position that is set to first break in the scope that two lines that angle that blade 110a becomes the plumb line at the radial section center with by oral area 39b is roughly ± 135 ° surround, and at least a portion of discharge opeing path is arranged on the part beyond the blade 110a within the scope of this.Further preferred, to be set to first break on the line of roughly+135 °, angle that blade 110a becomes the plumb line at the radial section center with by oral area 39b or-135 ° position, and at least a portion of discharge opeing path is arranged on the below on plumb line.

In addition, in said embodiment, discharge opeing path 110e makes bottle open the outer peripheral face depression of piston part 110 and form, but as shown in figure 16, discharge opeing path 110f is formed on bottle and opens the outer peripheral face of piston part 110, and consists of the groove thinner than thickness of pipe wall.According to this example, owing to not making bottle open the inner peripheral surface distortion of piston part 110, therefore have and make the advantage becoming simple.And, discontinuous owing to making to expand facial 110b, so breaking of occlusive part 39c also easily carried out.In addition in Figure 16, by a plurality of discharge opeing path 110f, along pipe circumferential array, can be also still in pipe week, upwards to there is a groove of large width.Similarly, the number of discharge opeing path 110e as shown in figure 13 also can be for arbitrarily.And, also can combine the discharge opeing path of depression and the discharge opeing path of otch is used.

Moreover, in said embodiment, use electronic three-way valve 114 from diluent stream 117 branch's cleanout fluid streams 113, the water of usining only sprays certain hour from bottle washer jet 112 as bottle cleanout fluid in first bottle 39, by switching electronic three-way valve 114, using water as diluent from diluent stream 117 to the interior injection of disinfectant solution tank 87, dilution concentrated solution 132.As an alternative, also can only with the cleanout fluid of washer bottle, dilute concentrated solution 132.Now, the time time of disinfectant solution 86 (modulation) of dilution concentrated solution 132 increases, but can omit electronic three-way valve 114 and diluent stream 117, thus have can simplification device advantage.And, in this embodiment, if measure the integrated flow of supplying with to bottle washer jet 112 by effusion meter 115, also can omit disinfectant solution sensor 119.

In said embodiment, after concentrated solution 132 is supplied with to disinfectant solution tank 87, use the bottle cleanout fluid spraying from bottle washer jet 112 and the diluent injecting from diluent stream 117 to dilute concentrated solution 132.As an alternative, can be also, first diluent be supplied with to disinfectant solution tank 87, then concentrated solution 132 be supplied with to disinfectant solution tank 87, finally bottle cleanout fluid be supplied with to disinfectant solution tank 87.Specifically, first a certain amount of diluent is supplied with to disinfectant solution tank 87 from diluent stream 117, then new bottle unit 38 is installed, and concentrated solution 132 and buffer agent are supplied with to disinfectant solution tank 87.Finally, a certain amount of bottle of cleanout fluid sprayed and clean first bottle 39 from bottle washer jet 112, and its rework solution is supplied with to disinfectant solution tank 87.In the rework solution of diluent, concentrated solution 132, bottle cleanout fluid, the level detection sensor or the effusion meter 115 that by use, are arranged in disinfectant solution tank 87 can measuring capacities.

Therefore like this, because concentrated solution 132 does not directly contact with the sealing member of disinfectant solution tank 87 and each sensor, can prevent the deterioration of disinfectant solution tank 87 and sealing member or in the situation of disinfectant solution tank 87 interior crystallizations.And, owing to also accessing according to the mixing effect of the sequentially feeding of diluent, concentrated solution 132, rework solution, therefore can make the CONCENTRATION DISTRIBUTION of disinfectant solution 86 more even.

In said embodiment, if open bottle, concentrated solution or buffer agent are directly supplied with to disinfectant solution tank 87.But, also can inject road 109 and buffer agent at concentrated solution and inject road electromagnetic valve is set, and temporarily stop concentrated solution or buffer agent to supply with to disinfectant solution tank 87.And when disinfectant solution modulating mode, CPU122 makes electromagnetic valve work, and concentrated solution or buffer agent are flowed to disinfectant solution tank 87.Like this, can carry out in advance the filling of bottle unit.

In addition, also can omit electronic three-way valve 114, and side by side to bottle washer jet 112 and disinfectant solution tank 87 both sides, supply with diluent, and side by side stop supplying with.

In order easily to open occlusive part, the blade that also bottle can be opened to piston part extends to expansion face, thereby omits expansion face.

The present invention also can be applicable to only have sterilizing function, and does not have the endoscope sterilizing device of cleaning function.And, also can be used in the decontaminating apparatus of medical apparatus such as treatment apparatus that endoscope uses or catheter etc.

The present invention is not limited to described embodiment, can in the scope that does not depart from main contents of the present invention, implement various distortion.
