Description

  The present invention relates to a disinfecting apparatus that supplies a concentrated liquid of a disinfecting liquid from a bottle to a disinfecting liquid tank and mixes the concentrated liquid and a diluting liquid in the disinfecting liquid tank to prepare a disinfecting liquid having a predetermined concentration.

  An endoscope is known as a medical device used for inspection and treatment in a body cavity of a living body. The endoscope includes an insertion portion that is inserted into a body cavity. The insertion portion is a flexible rod-like body, and includes an imaging portion that images the inside of the body cavity and various channels such as a forceps channel through which the treatment tool is inserted. In the endoscope after use, body fluid and dirt are attached to the outer surface of the insertion portion and each channel. Since pathogenic bacteria and viruses contained in body fluids and filth cause nosocomial infections, endoscopes after use are always cleaned and disinfected.

  In order to efficiently clean and disinfect an endoscope, an endoscope cleaning / disinfecting apparatus is used. The endoscope cleaning / disinfecting apparatus stores a used endoscope in a cleaning tank and automatically performs various processes such as a cleaning process and a disinfection process. In the washing step, water, detergent, or the like is sprayed onto the endoscope to wash away body fluids and dirt attached to the outer surface and each channel. In the disinfecting process, a predetermined amount of disinfecting liquid is supplied from a disinfecting liquid tank provided in the apparatus into the cleaning tank, and the endoscope is immersed in the disinfecting liquid stored in the cleaning tank. Pathogenic bacteria and viruses that have not been removed in the washing process are removed or disinfected with a disinfectant.

  For the disinfectant, for example, high-level disinfectants such as glutaraldehyde, ophthalphthalaldehyde and peracetic acid are used. Conventionally, glutaraldehyde has been frequently used, but at present, switching to peracetic acid has been progressing with a high disinfecting effect and less adverse effects on the human body.

  The disinfectant is prepared, for example, by supplying a concentrated solution of peracetic acid (hereinafter referred to as a concentrated solution) and a diluting solution (for example, water) into a disinfectant tank and mixing them to obtain a predetermined concentration. To do. For example, the concentrated liquid is treated as a deleterious substance because it has a peracetic acid concentration of 6% and contains 10% or more of hydrogen peroxide. The concentrate is put in a special bottle made of plastic.

  The bottle in which the concentrated liquid is sealed is attached to a bottle attaching portion provided in the endoscope cleaning / disinfecting apparatus. The concentrated liquid flows through the concentrated liquid injection path that connects the bottle mounting portion and the disinfecting liquid tank, and is supplied to the disinfecting liquid tank. A predetermined amount of water is supplied as a diluting liquid to the disinfecting liquid tank to which the concentrated liquid is supplied, thereby generating a predetermined concentration of the disinfecting liquid.

  Peracetic acid and its concentrate have a very strong odor. Therefore, if the odor of the concentrated liquid leaks to the outside of the sterilizer, the working environment is deteriorated. As a countermeasure against this odor leakage, a closed portion of a thin film made of silver paper or plastic is provided at the mouth of the bottle, and a protruding portion is provided at the bottle mounting portion, so that the blocking portion is attached when the bottle is attached to the bottle mounting portion. In this case, the liquid in the bottle is discharged by being separated and cut by the protrusions. According to this configuration, since the bottle and the bottle mounting portion are coupled in an airtight and liquid tight manner, the odor of the concentrated liquid remaining in the bottle is disinfected while the bottle is mounted on the bottle mounting portion. Never leak out. However, if the clogged portion is separated and cut, the cut clogged portion falls into the disinfectant tank, or the clogged clogged portion is clogged in the pipe connecting the bottle mounting part and the disinfectant tank. The problem occurs.

In order to prevent this problem, for example, in Patent Document 1, a cap attached to the mouth portion of the bottle is provided with a closing portion that closes the mouth portion, and the blade attaching portion, the extended surface portion, the relief portion, and the pressing portion are provided on the bottle attaching portion. Forming. When the bottle is inserted into the bottle mounting portion, the blade portion first forms a fracture portion in the closed portion, and the expansion surface portion expands the fracture portion according to the depth of penetration of the bottle. However, since the escape portion is provided, the broken portion is prevented from extending over the entire circumference of the closed portion. By the action of the pressing part, the closed part is bent inside the bottle with the joint part (the part of the closed part not separated from the cap) left by the escape part as a fulcrum, and a flow path for the concentrated liquid is formed in the bottle. The According to this configuration, since the closed portion does not come out of the bottle, the closed portion does not fall into the disinfecting liquid tank, or a trouble such as clogging in the pipeline connecting the bottle mounting portion and the disinfecting liquid tank does not occur. .

  A concentrated liquid injection path 109 provided at the upper part of the disinfectant tank 87 is attached to the first bottle mounting part 108. The concentrated liquid injection path 109 is composed of a pipe communicating with the disinfecting liquid tank 87. A tip portion of the concentrate injection path 109 (portion protruding into the first bottle attachment portion 108) serves as a bottle opening portion 110 for opening the mouth portion 39b of the first bottle 39.

  As shown in FIG. 5, the concentrate injection path 109 is a tubular member made of metal such as stainless steel, for example, and the bottle opening portion 110 that is a tip portion thereof is formed in order from the tip side with a blade portion 110 a and an expansion surface portion. 110b, a pressing part 110c, and an escape part 110d. Further, when the bottle opening part 110 is viewed from the bottle unit 38 side, a vertical line passing through the radial cross-sectional center of the bottle opening part 110 (same as the vertical line passing through the radial cross-sectional center of the mouth part 39b) L1 (FIG. 6). When the vertical upward direction is 0 o'clock, a liquid draining recess 110e is provided around the 6 o'clock position.

  The blade portion 110a has its center at, for example, 4:30 on the bottle opening portion 110. The blade part 110 a is inserted into the first bottle 39 by breaking the lid part 39 c when the mouth part 39 b of the bottle unit 38 is pushed into the first bottle attachment part 108.

  The expansion surface portion 110b abuts on the lid portion 39c and expands the broken portion of the lid portion 39c according to the insertion depth of the bottle unit 38. The relief part 110d has its center at a position facing the blade part 110a, for example at 10:30. The relief portion 110d is a surface that is angled on the back side of the concentrate injection path 109 with respect to the expansion surface portion 110b, and is configured not to contact the lid portion 39c. Thereby, the broken part of the lid part 39c expanded by the extended surface part 110b is prevented from extending over the entire circumference (the lid part 39c is broken from the mouth part 39b leaving the remaining part 39e (see FIG. 6). )

  The pressing portion 110c is a boundary between the expansion surface portion 110b and the relief portion 110d, and comes into contact with the lid portion 39c when the insertion depth of the bottle unit 38 reaches a certain value, and further increases the insertion depth of the bottle unit 38 therefrom. Then, the lid 39c is pushed up to the back side of the first bottle 39 while bending the remaining portion 39e. Thereby, a liquid flow path for discharging the concentrated liquid in the first bottle 39 is formed in the mouth portion 39b. The inner diameter of the mouth portion 39b is, for example, 34 mm, and the remaining portion 39e has a length of about 10 mm (arc angle 34 ° to 36 °).

  The liquid draining recess 110e serves as an opening for discharging the concentrated liquid from the outer peripheral side of the bottle opening part 110 to the concentrated liquid injection path 109. From the circular sectional shape of the inner periphery of the bottle opening part 110, Has a shape (groove shape) in which the peripheral surface of the bottle opening portion 110 is recessed so as to protrude radially inward. Thereby, a space is formed between the outer peripheral surface of the bottle opening part 110 and the inner peripheral surface of the concentrate injection path 109. In order to prevent the tip of the protruding portion of the liquid draining recess 110e inward in the radial direction of the bottle opening portion 110 from coming into contact with the lid portion 39c when the bottle unit 38 is inserted, it is located on the rear side (disinfection). It is located on the liquid tank 87 side).

  The positional relationship in the radial direction cross section of the bottle opening part 110 of the blade part 110a and the recessed part 110e for liquid draining is demonstrated using FIG. The center of the blade portion 110a (position at 4:30) is 135 ° (+ for clockwise and − for counterclockwise) with respect to the vertical line L1 passing through the center of the bottle opening portion 110 in the radial direction. Is on a straight line L2. When the blade portion 110a pushes through the lid portion 39c and is inserted into the first bottle 39, the concentrated liquid vigorously moves toward the broken portion (opening portion) of the lid portion 39c, but in the vicinity of the blade portion 110a. Therefore, the concentrated liquid does not collide with the bottle opening part 110 and passes through the liquid drained part 110e and is smoothly poured into the concentrated liquid injection path 109.

  The bottle opening portion 110 is integrally provided with a bottle cleaning nozzle 112 on the inner peripheral surface thereof. The center of the bottle cleaning nozzle 112 in the radial direction is, for example, at the 3 o'clock position of the bottle opening part 110. The tip of the bottle cleaning nozzle 112 is located on the back side (disinfecting liquid tank 87 side) from the extended surface portion 110b in order to prevent the bottle cleaning nozzle 112 from coming into contact with the lid portion 39c when the bottle unit 38 is inserted. A cleaning liquid flow path 113 (see FIG. 4) branched from the water supply path 76 is connected to the bottle cleaning nozzle 112.

  Although not shown in detail, the bottle housing portion 37 is also provided with a second bottle mounting portion for the second bottle 40. The second bottle mounting portion has the same shape as the first bottle mounting portion 108. A buffer injection path provided in the disinfectant tank 87 is connected to the second bottle mounting portion along with the concentrated liquid injection path 109. The buffer is supplied into the disinfectant tank 87 through the buffer injection path simultaneously with the concentrated liquid.

  In FIG. 4, a bottle sensor 116 that detects the bottle unit 38 is provided in the bottle housing portion 37. The bottle sensor 116 detects the bottle unit 38 when the first bottle 39 and the second bottle 40 are pushed into the first bottle mounting portion 108 and the second bottle mounting portion.

  The cleaning liquid channel 113 is branched from the diluent channel 117. In the dilution liquid channel 117, an electromagnetic valve 111, an electric three-way valve 114, and a flow meter 115 are provided in this order from the water supply channel 76 side. A diluent flow path 117 is connected to the inlet of the electric three-way valve 114, a diluent flow path 117 is connected to one outlet, and a cleaning liquid path 113 is connected to the other outlet. The diluent flow path 117 is directly connected to the disinfectant tank 87. By switching the electric three-way valve 114, it is selected whether water is supplied to the diluent flow path 117 or water is supplied to the cleaning liquid flow path 113.

  The flow meter 115 measures the instantaneous flow rate of water supplied to the cleaning liquid channel 113. The WP 80 is controlled based on the instantaneous flow rate data from the flow meter 115, and the supply pressure of tap water to the water supply channel 76 is adjusted. Water sprayed from the bottle cleaning nozzle 112 into the first bottle 39 cleans the first bottle 39 as a bottle cleaning liquid. Thereafter, when the CPU 122 (see FIG. 7) measures a certain time (when the integrated flow rate of the water supplied to the cleaning liquid channel 113 reaches a certain value), the electric three-way valve 114 moves from the cleaning liquid channel 113 side to the dilute liquid flow. It is switched to the path 117 side, and water (diluent) is poured into the disinfectant tank 87 from the dilute path 117. When water passes through the diluent flow path 117, the water supply pressure by the WP 80 is higher than when water passes through the cleaning liquid flow path 113. As a result, a prescribed amount of diluent can be supplied into the disinfectant tank 87 in a short time.

  In the disinfecting liquid tank 87, a concentrated liquid sensor 118 that detects the liquid level of the liquid and turns on, and a disinfecting liquid sensor 119 are provided. The concentrated liquid sensor 118 and the disinfecting liquid sensor 119 are attached to the disinfecting liquid tank 87 from the outside of the disinfecting liquid tank 87 by using, for example, holes formed in the disinfecting liquid tank 87. Between the hole of the disinfecting liquid tank 87 and the concentrated liquid sensor 118 and the disinfecting liquid sensor 119, a packing for preventing the disinfecting liquid 86 from leaking is attached. For this packing, PP having resistance against peracetic acid, polyethylene (PE) or the like is used.

  The concentrated liquid sensor 118 detects a prescribed amount of the concentrated liquid and buffer to be supplied from the bottle unit 38. The disinfecting liquid sensor 119 detects the supply amount of the diluting liquid to be supplied in order to prepare a disinfecting liquid 86 having a predetermined concentration by diluting a predetermined amount of the concentrated liquid and buffer stored in the disinfecting liquid tank 87. To do. In the present invention, not only the water supplied from the diluent flow path 117 but also the bottle cleaning liquid returned from the first bottle 39 is used as the diluent. Therefore, when the total amount of water supplied from the bottle cleaning liquid flowing from the first bottle 39 into the disinfecting liquid tank 87 and the water supplied from the diluent flow path 117 reaches a predetermined amount, the disinfecting liquid sensor 119 The liquid level of the liquid in which the buffer and the diluent are mixed is detected.

  As shown in FIG. 7, the apparatus 28 includes a CPU 122 that controls the entire apparatus, a ROM 123 that stores a control program and various data, and a RAM 124 that is an execution area of the control program read from the ROM 123. I have. Sensors such as a liquid level sensor 66, a temperature sensor 72, a flow meter 115, a bottle sensor 116, a concentrated liquid sensor 118, and a disinfectant liquid sensor 119 are connected to the CPU 122. Also connected to the CPU 122 are an LCD driver 125 that drives the display panel 34, a valve driver 126 that drives each electromagnetic valve, a motor driver 127 that drives the electric three-way valves 75 and 114, and the like. A WP driver 128 that drives each WP, a heater driver 129 that drives the rubber heater 71, and the like are also connected to the CPU 122.

  The apparatus 28 has a plurality of operation modes such as a cleaning / disinfecting mode, a disinfecting liquid preparation mode, and a disinfecting liquid discharge mode. Each mode is selected by operating the operation panel 33. Hereinafter, the disinfecting liquid preparation mode for preparing a new disinfecting liquid 86 in the disinfecting liquid tank 87 will be described with reference to the flowchart of FIG. 8 and FIG. 9.

  When the device 28 is set to the disinfecting liquid preparation mode by operating the operation panel 33 (S1), the CPU 122 sets the disinfecting liquid 86 in the disinfecting liquid tank 87 based on the signals of the concentrated liquid sensor 118 and the disinfecting liquid sensor 119. The presence or absence is confirmed (S2). When the disinfecting liquid 86 is stored in the disinfecting liquid tank 87 (Y in S2), the CPU 122 opens the electromagnetic valve 92 to discharge the disinfecting liquid 86 in the disinfecting liquid tank 87 (S3). When there is no disinfecting liquid 86 in the disinfecting liquid tank 87 (N in S2), the CPU 122 accepts the installation of a new bottle unit 38 (S4). It is preferable that a predetermined amount of diluent is supplied into the disinfectant tank 87 after the disinfectant 86 is discharged, and the disinfectant tank 87 is cleaned.

  As shown in FIG. 9 (A), the bottle unit 38 storing the concentrated liquid 132 and the buffering agent is laid diagonally so that the mouth portion 39b faces downward, and the bottle housing portion is opened from the mouth portion 39b side. 37. The bottle unit 38 is placed on the bottom surface portion 107.

  As shown in FIG. 9B, the bottle unit 38 is slid on the bottom surface portion 107, and the mouth portion 39 b is pushed into the first bottle attachment portion 108. According to the insertion depth of the bottle unit 38, the blade part 110a pushes and breaks the lid part 39c, and the extended surface part 110b expands the fractured part of the lid part 39c. However, the relief part 110d and the pressing part 110c act to open the lid part. 39c is not completely separated from the mouth portion 39b, and a liquid flow path is formed in the mouth portion 39b by bending the remaining portion 39e. At this time, since the first bottle mounting portion 108 is fitted to the outer periphery of the mouth portion 39 b so as to be airtight and liquid tight, the odor of the concentrated liquid 132 does not leak from the first bottle 39. Although not described in detail, the second bottle 40 is fitted to the second bottle mounting portion in the same manner as the first bottle 39.

  When the lid 39c is broken, the concentrate 132 and the buffer in the bottle unit 38 flow into the disinfectant tank 87 through the concentrate injection path 109 and the buffer injection path. At this time, as shown in FIG. 10, the concentrated solution is along the side surface 39 d of the first bottle 39, the opening portion in the vicinity of the blade portion 110 a, particularly the lowest portion in the radial direction of the bottle opening portion 110 (at 6 o'clock). However, since there is a liquid draining recess 110e at this position, collision between the concentrated liquid 132 and the bottle opening part 110 is avoided, and the concentrated liquid passes through the liquid draining concave part 110e to inject the concentrated liquid. It is poured into the path 109. Since the concentrated liquid 132 does not flow into the bottle opening part 110 at a stretch, there is no possibility that the liquid overflows from the bottle opening part 110, and the concentrated liquid rebounds due to the collision between the concentrated liquid 132 and the bottle opening part 110. Therefore, the concentrated liquid can be smoothly poured into the disinfecting liquid tank 87 without disturbing the liquid flow.

  The concentrated liquid sensor 118 detects the liquid level where the concentrated liquid 132 and the buffering agent are mixed, and turns on (Y in S5). The bottle sensor 116 detects the bottle unit 38 accommodated in the bottle accommodating portion 37 and is turned on. In addition, the CPU 122 performs measurement for a predetermined time after the bottle sensor 116 is turned on. When the concentrate sensor 118 is not turned on within a predetermined time (N in S5), there is a possibility that an empty bottle unit 38 or a bottle unit 38 with a small amount of the concentrate 132 or the like is set. For example, error processing such as displaying an error message on the display panel 34 is performed (S6). As a cause of the error in which the concentrated liquid 132 or the like is not detected, a liquid supply mistake such as leakage of the concentrated liquid 132 or the like outside the disinfecting liquid tank 87 may be considered.

  As shown in FIG. 9C, the CPU 122 opens the electromagnetic valves 78 and 111 in response to the ON signal of the concentrate sensor 118. Further, the electric three-way valve 114 is switched to the cleaning liquid channel 113 side. The water that has flowed through the water supply channel 76 and the cleaning liquid channel 113 is sprayed into the first bottle 39 from the bottle cleaning nozzle 112 as a bottle cleaning liquid 136 (S7). As a result, the concentrated liquid 132 remaining in the first bottle 39 is washed away by the bottle cleaning liquid 136. In the disinfectant preparation mode, the electric three-way valve 75 is switched so as to connect the liquid supply path 74 and the first circulation path 103, so that water does not flow into the cleaning tank 31.

  The flow meter 115 measures the instantaneous flow rate of the water flowing in the cleaning liquid flow path 113 and sends data to the CPU 122. The CPU 122 monitors whether the instantaneous flow rate is within a predetermined range (S8). For example, this range is 5-6 liters / minute. When the instantaneous flow rate is out of the predetermined range (N in S8), the CPU 122 controls the water supply pressure by the WP 80 via the WP driver 128 so that the instantaneous flow rate is within the predetermined range (S9). The appropriate instantaneous flow rate range varies depending on the size of the first bottle 39, the position of the nozzle 112, the inclination angle of the bottom surface portion 107, and the like.

  At this time, as shown in FIG. 6, the bottle cleaning liquid 136 (returned liquid) that is sprayed from the bottle cleaning nozzle 112 and cleans the inside of the first bottle 39 and then passes through the bottle opening part 110 toward the disinfecting liquid tank 87. The bottle cleaning nozzle 112 is at a higher position than the liquid level (water level) in the radial cross section of the bottle opening portion 110. Thus, by appropriately controlling the flow rate of the return liquid, the return liquid and the bottle cleaning nozzle 112 can be prevented from interfering with each other, and the return liquid may collide with the bottle cleaning liquid 136 ejected from the nozzle 112. Is prevented. Therefore, the bottle cleaning liquid 136 ejected from the nozzle 112 can surely reach the back of the first bottle 39, and the first bottle 39 can be effectively cleaned. In FIG. 6, the lid portion 39c other than the remaining portion 39e is drawn so as to be in contact with the mouth portion 39b, but actually, the lid portion 39c other than the remaining portion 39e is not in contact with the mouth portion 39b. . Therefore, the water level of the return liquid of the bottle cleaning liquid 112 can be up to the height of the edge of the remaining portion 39e when the position of the bottle cleaning nozzle 112 is not considered.

  In addition, the hatching part of FIG. 6 represents the position of the cover part 39c bent. The lid 39c closes a part of the bottle opening part 110 in the radial direction with the remaining part 39e in the direction of 10:30 as the center, and this part is connected to the bottle washing nozzle 112 centering on the 3 o'clock direction. Does not interfere. Thus, it is preferable to position the remaining portion 39e and the bottle cleaning nozzle 112 so that the lid portion 39c, the bottle cleaning nozzle 112, and the return liquid do not interfere with each other.

  When the CPU 122 measures the predetermined time (Y in S10), the CPU 122 drives the motor driver 127 to switch the electric three-way valve 114 from the cleaning liquid flow path 113 side to the dilution liquid flow path 117 side (S11). The predetermined time is, for example, 20 seconds. Thereby, the ejection of the bottle cleaning liquid 136 from the bottle cleaning nozzle 112 stops, and water (diluted liquid) is poured into the disinfecting liquid tank 87 from the diluent flow path 117. When the water passes through the diluent flow path 117, the CPU 122 increases the water supply pressure by the WP 80 via the WP driver 128 more than when it passes through the cleaning liquid flow path 113 (S12). For example, the water supply pressure by the WP 80 is controlled so that the flow rate of water passing through the diluent channel 117 is 10 to 12 liters / minute. Thereby, compared with the case where the concentrate 132 is diluted only with the bottle cleaning liquid 136 from the bottle cleaning nozzle 112, the concentrate 132 can be diluted in a short time (dilution of a prescribed amount of water in the disinfectant tank 87). The advantage of being able to supply liquid) is born. The timing for switching the electric three-way valve 114 may be after the flow meter 115 measures a predetermined integrated flow rate, instead of after the CPU 122 measures a predetermined time.

  The bottle cleaning liquid 136 that has flowed into the disinfecting liquid tank 87 through the bottle opening part 110 and the concentrated liquid injection path 109 and the water poured into the disinfecting liquid tank 87 from the diluting liquid channel 117 are used as the concentrated liquid 132. A disinfectant solution 86 is prepared by dilution. When the liquid level of the disinfecting liquid 86 reaches the disinfecting liquid sensor 119, the disinfecting liquid sensor 119 is turned on (Y in S13). The CPU 122 closes the electromagnetic valves 78 and 111 via the valve driver 126 in response to the ON signal of the disinfecting liquid sensor 119, and stops supplying the diluting liquid (S14). Thereby, the preparation of the disinfecting liquid 86 having a predetermined concentration in the disinfecting liquid tank 87 is completed. For example, the disinfecting solution 86 is obtained by diluting a concentrated solution 132 of 6% peracetic acid 20 times.

  The disinfecting liquid 86 prepared as described above is used in the disinfecting process after the cleaning process and the rinsing process of the endoscope 10. In the sterilization process, the CPU 122 drives the WP 88 to suck the sterilization liquid 86 in the sterilization liquid tank 87 and supplies a predetermined amount of the sterilization liquid 86 into the cleaning tank 31. The disinfectant liquid 86 is heated by the rubber heater 71. The disinfectant 86 is circulated in the cleaning tank 31 and the channels 15 to 17 of the endoscope 10 to remove pathogens and viruses that have not been washed away in the cleaning process or to eliminate pathogenicity. After the disinfection process is completed, the disinfecting liquid 86 is returned to the disinfecting liquid tank 87 through the waste liquid paths 94 and 96. Finally, the cleaning and disinfection of the endoscope 10 is completed through a rinsing process for removing the disinfecting solution 86 and a drying process for drying the channels 15 to 17 of the endoscope 10 with air supply and alcohol.

  As described above, the liquid drainage portion 110e is provided in the vicinity of the blade portion 110a of the bottle opening portion 110, and immediately after the lid portion is broken by the blade portion 110a, the concentrate is concentrated in the concentrate injection path 109 through the liquid drainage portion 110e. Since the liquid 132 is guided, there is a problem that the liquid is overflowed from the bottle mounting portion 108 when a large amount of the concentrated liquid 132 is poured at the same time as the lid portion 39c is broken, or the concentrated liquid 132 is removed from the blade portion 110a or It is possible to prevent a problem that the liquid flow is disturbed by colliding with the extended surface portion 110b in the vicinity of the blade portion and greatly rebounding.

  In the above embodiment, the blade portion 110a is centered on the 4:30 position of the bottle opening portion 110, and the drainage recess 110e is centered on the 6 o'clock position of the bottle opening portion 110. It is provided as follows. Accordingly, the liquid draining recess 110e is on a vertical line passing through the center of the radial section of the mouth part 39b, and the blade part 110a is on a straight line forming an angle of 135 ° with respect to the vertical line. However, the position of the blade part 110a and the recessed part 110e is not limited to this.

  For example, as shown in FIG. 11, the bottle opening part 110a is provided so that the bottle opening part 110 is centered on the 5 o'clock position (on a straight line forming an angle of 150 ° with respect to the vertical line L1). The drainage recess 110e may be provided so that the position at 6:30 (on a straight line forming an angle of −165 ° with respect to the vertical line L1) of the portion 110 is the center. According to this example, the blade part 110a can be brought closer to the 6 o'clock position. In this example, a part of the liquid draining recess 110e is at the 6 o'clock position of the bottle opening part 110 (when the lid part 39c is broken when the blade part 110a is in the vicinity on the vertical line L1, the concentrated liquid 132 is the most. Where the momentum increases). Thus, as long as the blade part 110a is in the vicinity of the liquid draining part, the position of the liquid draining concave part can be changed according to the design of the bottle opening part 110.

  However, from the viewpoint of releasing the momentum of the concentrated liquid immediately after the lid breaks, which is the object of the present invention, by the drainage part, the blade part 110a is formed with a vertical line passing through the radial center of the mouth part 39b. It is preferably provided at a position where the angle is first broken within a range of a line of approximately ± 135 °, and at least a part of the liquid drainage part is provided at a part other than the blade part 110a within the range. . More preferably, the blade portion 110a is provided at a position where the angle formed with the vertical line passing through the radial cross-sectional center of the mouth portion 39b first breaks on a line of approximately ± 135 °, and at least one of the liquid drainage portions. The part is provided on a vertically downward line of the vertical line.

  Moreover, in the said embodiment, although the recessed part 110e for draining is formed so that it may have a protrusion part to the radial inside of the bottle opening part 110, as shown in FIG. A minute recess 110f (slit-like groove) cut out from the outer peripheral surface at a depth smaller than the pipe thickness may be provided instead of the recess 110e. According to this example, since the inner peripheral surface of the bottle opening part 110 is not deformed, there is an advantage that processing is easy. Moreover, since the extended surface portion 110b is not greatly cut out, the lid portion 39c is easily broken. In FIG. 12, a plurality of minute recesses 110f are arranged in the pipe circumferential direction. However, the number of the minute recesses 110f is not limited. For example, one minute recess 110f having a wide width in the pipe circumferential direction may be provided. Good. Similarly, even when the liquid draining recess 110e having the protruding portion is used, the number of the recesses is not limited. For example, a plurality of recesses 110e having a narrow width in the pipe circumferential direction may be provided. Also, the liquid drain recess 110e and the minute recess 110f may be used in combination.

  In the above embodiment, the relief part 110d of the bottle opening part 110 is arranged at 10:30, and the bottle cleaning nozzle 112 is integrally provided at the 3 o'clock position of the bottle opening part 110. The arrangement of the relief part 110d and the bottle cleaning nozzle 112 is not limited to the above, and the interference between the return liquid of the bottle cleaning liquid 136 and the bottle cleaning nozzle 112, and the lid part 39c bent in the first bottle 39 and the bottle cleaning nozzle 112. Any arrangement may be used as long as it can prevent interference.

  In the above-described embodiment, one bottle cleaning nozzle 112 is provided integrally with the bottle opening part 110, but two or more bottle cleaning nozzles may be provided integrally with the bottle opening part 110. Furthermore, in the above-described embodiment, the bottle cleaning nozzle having a circular cross section is provided integrally with the bottle opening part 110, but it may be a separate body, and the cross sectional shape of the nozzle is not limited to a circle. You may use the bottle washing nozzle which has a slit-shaped jet nozzle along the radial direction cross-section curve of the stopper part 110. FIG.

  In the above-described embodiment, the instantaneous flow rate of the bottle cleaning liquid 136 supplied to the bottle cleaning nozzle 112 is measured by the flow meter 115 as a measuring unit that measures the ejection amount of the bottle cleaning liquid 136 from the bottle cleaning nozzle 112. The measuring means and method are not limited to this, and a measuring means and method for measuring at least one of the instantaneous flow rate, the integrated flow rate, and the ejection time of the bottle cleaning liquid 136 may be used. For example, the instantaneous flow rate, the integrated flow rate, and the ejection time may be estimated based on the WP driving time or the like without using a flow meter.

  In the above embodiment, the cleaning liquid flow path 113 is branched from the dilution liquid flow path 117 using the electric three-way valve 114, and water (bottle cleaning liquid 136) is supplied from the bottle cleaning nozzle 112 through the cleaning liquid flow path 113 for a predetermined time. After injecting into the inside, the electric three-way valve 114 is switched so that water (diluent) is poured into the disinfectant tank 87 from the dilute channel 117 to dilute the concentrate 132. All the water for diluting the water may be passed through the bottle washing nozzle 112. According to this example, it takes a lot of time to dilute the concentrated liquid 132 (time to prepare the disinfecting liquid 86), but it becomes possible to omit the electric three-way valve 114 and the diluting liquid flow path 117, thereby simplifying the apparatus. There is a merit that you can. In this example, if the integrated flow rate supplied to the bottle cleaning nozzle 112 is measured by the flow meter 115, the disinfecting liquid sensor 119 can be omitted.

  In the above embodiment, after the concentrated liquid 132 is supplied to the disinfecting liquid tank 87, the bottle cleaning liquid 136 ejected from the bottle cleaning nozzle 112 and the water poured from the diluent flow path 117 are supplied to the disinfecting liquid tank 87. Although the disinfecting liquid 86 is prepared by diluting the concentrated liquid 132, the disinfecting liquid 86 may be prepared by supplying the diluted liquid to the disinfecting liquid tank 87 before the concentrated liquid 132.

  Specifically, first, a fixed amount of water (diluent) is supplied from the diluting liquid flow path 117 to the disinfecting liquid tank 87, and then the attachment of a new bottle unit 38 is accepted, and the concentrated liquid 132 and the buffer are removed from the disinfecting liquid tank 87. Finally, a certain amount of bottle cleaning liquid 136 is sprayed from the bottle cleaning nozzle 112 to clean the first bottle 39, and its return water is supplied to the disinfecting liquid tank 87 to prepare the disinfecting liquid 86. The amount of each of the diluted liquid, the concentrated liquid 132, and the bottle cleaning liquid 136 can be measured by using a liquid level detection sensor provided in the disinfecting liquid tank 87 or the flow meter 115.

  According to this example, the concentrated liquid 132 does not directly touch the disinfecting liquid tank 87 and the packing of each sensor, so that it is possible to prevent the disinfecting liquid tank 87 and the packing from being deteriorated and crystals are deposited in the disinfecting liquid tank 87. Can do. In addition, since the stirring effect is obtained by supplying the diluted solution, the concentrated solution 132, and the bottle cleaning solution 136 in this order, the concentration distribution of the disinfecting solution 86 can be made more uniform.

  In each of the above-described embodiments, the concentrated liquid 132 is substantially supplied by the user, but may be automatically performed by the device 28. For example, electromagnetic valves are provided in the concentrate injection path 109 and the buffer injection path, and the timing at which the concentrate 132 or the like is supplied from the bottle unit 38 to the disinfectant tank 87 is determined by the apparatus 28 itself. Moreover, although each said embodiment demonstrated the structure and process for wash | cleaning the 1st bottle 39 which enclosed the concentrate 132, the same structure and process are applied to the 2nd bottle 40 which enclosed the buffer. Applicable.

  The present invention can also be applied to an endoscope disinfection device that does not have an endoscope cleaning function. It can also be used for disinfection devices such as endoscope treatment tools and other medical instruments. The present invention is not limited to the above-described embodiment, and various modifications can be made without departing from the spirit of the invention.
