Therefore, it is possible to provide a thin endoscope cleaning / disinfecting apparatus having excellent workability during maintenance and inspection.

  The bottom surface of the casing can be arranged only on both the left and right sides when viewed from the direction in which the internal structure is pulled out. Further, it is preferable that the internal structure can be pulled out to the operation surface side because it is easy to pull out, there is no need to change the orientation of the apparatus, and maintenance inspection after the internal structure is pulled out is easy. On the other hand, the internal structure includes a pulley and is placed on the bottom surface of the casing with the pulley sandwiched between when the internal structure is manually pulled out from the casing and when the internal structure is manually stored in the casing. This is preferable in that the operability can be improved. A mode in which only one pair of the pulleys is arranged on the left and right in front of the inner structure as viewed from the direction in which the inner structure is housed in the housing is preferable. In this aspect, when the internal structure is moved, smooth movement is possible, and during the maintenance inspection after the internal structure is pulled out, the internal structure does not move, so that the workability of the maintenance inspection can be improved.

  A mode in which a transparent upper tank is formed on the processing tank, a transparent lower tank is formed below the processing tank, and a sensor for managing water supply and drainage is disposed outside the upper tank and the lower tank. Such an embodiment prevents the dirt component floating in the processing tank from adhering to the sensor, and can avoid malfunction of the sensor. On the other hand, when the sterilization time is set in advance before the sterilization and the sterilization time elapses, the alarm is generated in order to ensure the sterilization effect of the disinfectant and to use the disinfectant as long as possible. It is preferable. In addition, when the number of times of sterilization and sterilization is set in advance, and the number of times of sterilization and sterilization has passed, the mode of generating an alarm can ensure a high level of sterilization and sterilization effect even after using different disinfectants. The objectivity can be given to the judgment of the collection and discharge of the disinfectant.

  The small-diameter endoscope includes a treatment endoscope in which an insertion portion that is inserted into an affected area in diagnosis / treatment of a patient and an operation portion that operates the insertion portion, and a suction port and a forceps port are arranged in the operation portion. is there.

It is a figure which illustrates schematically the other aspect of the piping system of the small diameter endoscope washing | cleaning disinfection apparatus of this invention.

  FIG. 1 is a conceptual diagram illustrating the structure of a thin endoscope cleaning / disinfecting apparatus of the present invention. As shown in FIG. 1, the small-diameter endoscope cleaning / disinfecting apparatus of the present invention has a housing 1 and an internal structure 2 placed on the bottom surface of the housing 1. To place means to place. FIG. 1A shows a state in which the internal structure 2 is housed in the housing 1, and FIG. 1B shows a state in which the internal structure 2 is pulled out from the housing 1. As shown in FIG. 1, a processing tank 3 is connected to the internal structure 2. When the endoscope is cleaned and disinfected, the insertion portion of the small-diameter endoscope is accommodated in the processing tank 3 and the operation portion of the small-diameter endoscope is placed on the holding portion 4.

  The internal structure 2 includes a cleaning water supply system, a detergent liquid supply system, a disinfectant liquid supply system, a bubble supply system, and a discharge system in the region 5. The cleaning water supply system supplies cleaning water for rinsing cleaning to the treatment tank, and the detergent liquid supply system supplies detergent liquid for cleaning detergent to the processing tank. The disinfecting liquid supply system supplies a disinfecting liquid for sterilizing and disinfecting to the processing tank, and the bubble supplying system is provided at the bottom of the processing tank at least one of rinsing cleaning, detergent cleaning, and sterilizing disinfection. More bubbles are supplied, and the drainage system discharges the processing liquid in the processing tank.

  Many small-sized endoscopes have a small outer diameter of 2 mm to 3 mm, with the outer diameter of the insertion portion inserted into the affected area being as thin as 6 mm or less. The length of the insertion portion is generally 40 cm or less, and a small size of about 30 cm is often used. As described above, since the small-diameter endoscope has a small insertion portion, the patient suffers less pain at the time of diagnostic treatment. In addition, since it can be inserted into the pores, it is used for diagnosis and treatment of the nasal cavity, pharynx, larynx and ears in otolaryngology, in the urology department for diagnosis of the bladder through the urethra, and in the gynecology department, Used for diagnosis.

  For this reason, unlike the colonoscopy cleaning / disinfecting apparatus and the like, the internal structure of the small-diameter endoscope cleaning / disinfecting apparatus is light weight of about 12.5 kg. Therefore, in the small-diameter endoscope cleaning / disinfecting apparatus, the internal structure 2 can be manually pulled out from the housing 1, and the pulled-out internal structure 2 can be manually stored in the housing 1. The small-diameter endoscope cleaning / disinfecting apparatus is used in the housed state of FIG. 1A when cleaning and disinfecting the small-diameter endoscope. Further, in the maintenance and inspection of the small-diameter endoscope cleaning / disinfecting apparatus, the internal structure 2 is manually moved from the housing 1 in the direction of the arrow as shown in FIG. 1 (b) from the housed state of FIG. 1 (a). It can be pulled out. For this reason, the internal structure can be freely observed from the back direction depending on the upward direction, the right lateral direction, the left lateral direction, and the device structure, and a finger can be freely inserted. In addition, after the maintenance inspection, the pulled-out internal structure can be easily stored manually in the housing.

  Therefore, according to the present invention, it is possible to provide a small-diameter endoscope cleaning / disinfecting apparatus having excellent workability during maintenance and inspection. In addition, the maintenance and inspection of the cleaning / disinfecting apparatus becomes easy and the working time can be shortened, so that the operating time of the cleaning / disinfecting apparatus can be extended, and as a result, it contributes to smooth diagnosis and treatment by the endoscope. Furthermore, since the cleaning and disinfecting apparatus can be repaired immediately and can be easily repaired at the medical site, it is not necessary to lend an alternative device to the medical site.

  In the aspect illustrated in FIG. 1, the internal structure 2 can be pulled out from the housing 1 toward the operation surface (direction of the arrow shown in FIG. 1B). In a medical field, a small-diameter endoscope cleaning / disinfecting apparatus is often arranged with a back surface facing a wall of a room. For this reason, since the embodiment illustrated in FIG. 1 has few obstacles when pulling out the internal structure, it is easy to pull out, and there is no need to change the orientation of the apparatus. Furthermore, it is preferable in that the maintenance inspection after the internal structure is pulled out is easy. In such an embodiment, the housing 1 does not necessarily need to be provided with a plate-like body on the back side (the direction opposite to the arrow shown in FIG. 1B). On the other hand, the small-diameter endoscope cleaning / disinfecting device does not have to be placed with the back side facing the wall of the room. For example, the internal structure can be pulled out in other directions.

  FIG. 2 is a diagram schematically illustrating a piping system of the thin endoscope cleaning / disinfecting apparatus of the present invention. As shown in FIG. 2, when performing the cleaning / disinfecting process, the insertion portion 6 of the small-diameter endoscope is housed in the processing tank 3, and the operation portion 7 of the small-diameter endoscope is placed on the holding portion 4. The control unit shown in FIG. 2 includes a CPU, a memory, a database, a display, and the like (not shown). When performing the cleaning / disinfecting process, the CPU transmits a control signal to the components of the small-diameter endoscope cleaning / disinfecting apparatus based on the data recorded in the database according to the program recorded in the memory, Control and perform a series of cleaning and disinfection processes. In the present embodiment, an example in which the cleaning and disinfecting process is performed using the control unit is shown, but a mode in which the state is visually confirmed and operated manually is also possible. In addition, a part of the process can be manually operated by the control unit and the remaining part can be manually operated.

  When rinsing and washing is performed by the washing water supply system, as shown in FIG. 2, the control unit transmits a control signal to the electromagnetic valve V1, and the electromagnetic valve V1 is opened, for example, for rinsing washing of tap water or the like. The cleaning water is sent to the lower tank 9 disposed below the processing tank 3, and the cleaning water is supplied to the processing tank 3. A transparent upper tank 8 is formed on the processing tank 3, a sensor 10 is disposed in the upper tank 8, and when the processing tank 3 is full of water, the sensor 10 transmits detection information to the control unit. The received control unit transmits a control signal to the electromagnetic valve V1 and stops the supply of the cleaning water. Such an aspect is preferable in that water supply can be managed. Moreover, the aspect which arrange | positions the sensor 10 which manages water supply outside the transparent upper tank 8 can prevent that the dirt component which floats in the processing tank adheres to the sensor 10, and can avoid the malfunctioning of the sensor 10. This is preferable. As the liquid detection sensor 10, a capacitance type sensor can be preferably used.

  Treatment liquid such as cleaning water is supplied to the lower tank 9 rather than supplied to the upper tank 8, and the supply of the sensor 10 functions more accurately in terms of suppressing foaming in the treatment tank 3. It is preferable in that the liquid to be mixed is easy to mix and the working time can be shortened. The same applies to the supply of detergent liquid and disinfectant liquid.

  At the time of rinsing, when supplying bubbles from the lower part of the processing tank 3, the control unit transmits a control signal to the air pump P 2, and the received air pump P 2 is a bubble generating unit disposed at the lower part of the processing tank 3. 12 is supplied with air. Since the bubble generation unit 12 is formed of a porous material, supplying air to the bubble generation unit 12 discharges small diameter bubbles into the treatment tank 3 and disperses a large amount of small diameter bubbles in the liquid. Can do. The same applies when bubbles are supplied at the time of detergent cleaning or sterilization.

  Since the small-diameter bubbles are negatively charged, the small-diameter bubbles are difficult to coalesce and are stable in the liquid. In addition, since the small diameter bubble has a small buoyancy, it has a strong tendency to float in the liquid. On the other hand, dirt components such as proteins adhering to the surface of the insertion portion of the endoscope are positively charged, so that they are easily electrically coupled to small-sized bubbles charged negatively, Easy to incorporate on the surface. In addition, when a small-sized bubble that is negatively charged is combined, the positive charge of the dirt component is neutralized, and thus the separation of the dirt component from the insertion portion is promoted. Furthermore, since the bubbles adsorbed with the dirt component increase in buoyancy and rise, there is a function of preventing the dirt component such as protein from reattaching to the insertion portion.

  Therefore, by using the small-diameter bubble, it is possible to avoid damage caused by hand washing of the endoscope insertion portion and to exert a high cleaning effect. For this reason, the frequency | count of rinsing washing | cleaning reduces, reduction of the amount of water used, a power saving, and shortening of processing time are realizable. Similar to the rinsing and cleaning, the small-sized bubble exerts the same function in detergent cleaning and sterilization and disinfection, and enhances the cleaning effect and the sterilization and disinfection effect.

  When the treatment liquid after rinsing and cleaning in the treatment tank is discharged by the discharge system, as shown in FIG. 2, the control unit transmits a control signal to the electromagnetic valve V3, the electromagnetic valve V3 is closed, and the electromagnetic valve A control signal is transmitted to V4, and the solenoid valve V4 opens. In addition, the control unit transmits a control signal to the pump P <b> 1 and discharges the processing liquid in the processing tank 3 from the lower tank 9. When rinsing is performed a plurality of times, the supply and discharge of these cleaning waters are repeated. When the sensor 11 is disposed in the lower tank 9 below the processing tank 3 and the discharge of the processing liquid is completed, the sensor 11 transmits detection information to the control unit, and the control unit transmits a control signal to the pump P1, A mode in which the discharge of the treatment liquid is stopped is preferable in that the drainage can be managed. Moreover, the aspect which arrange | positions the sensor 11 which manages waste_water | drain outside the transparent lower tank 9 can prevent that the dirt component which floats in the processing tank adheres to the sensor 11, and can avoid the malfunctioning of the sensor 11. Is preferable. As the sensor 11 for detecting liquid, a capacitance type sensor can be preferably used. The same applies to the discharge of the treatment liquid after washing with the detergent and the discharge of the treatment liquid after sterilization.

  When supplying detergent liquid for detergent cleaning to the processing tank by the detergent liquid supply system, as shown in FIG. 2, the control unit transmits a control signal to the electromagnetic valve V1, and the electromagnetic valve V1 opens. . Further, the control unit transmits a control signal to the pump P4 to start the pump P4, mixes the detergent solution (stock solution) with the washing water at a predetermined ratio, sends it to the lower tank 9, and supplies the detergent solution to the treatment tank 3. Supply. When the processing tank 3 is filled with the detergent solution, the sensor 10 in the upper tank 8 detects it and transmits the detected information to the control unit. The control unit transmits a control signal to the electromagnetic valve V1, and the electromagnetic valve V1 is closed. Simultaneously with the operation, a control signal is transmitted to the pump P4, and the pump P4 is stopped. Thereafter, bubbles can be supplied by the bubble supply system, and after washing with the detergent, the treatment liquid in the treatment tank 3 is discharged by the discharge system. When the detergent cleaning process is completed by cleaning the detergent and discharging the processing liquid, the mode of supplying water from the upper part of the processing tank 3 eliminates bubbles remaining in the processing tank and reduces malfunction of the machine. It is preferable at the point which can do. When a plurality of detergent cleanings are performed, the supply and discharge of these detergent liquids are repeated, and after the detergent cleaning, rinsing cleaning can be performed using a cleaning water supply system.

  When supplying the disinfecting liquid for sterilization and disinfection to the processing tank by the disinfecting liquid supply system, as shown in FIG. 2, the control unit transmits a control signal to the electromagnetic valve V3, and the electromagnetic valve V3 is closed. Then, a control signal is transmitted to the pump P3, and the pump P3 sends the disinfecting liquid in the disinfecting liquid tank to the lower tank 9 and supplies the disinfecting liquid to the processing tank 3. The disinfectant tank is refilled with disinfectant as necessary. When the treatment tank 3 is filled with the disinfecting liquid, the sensor 10 in the upper tank 8 detects it and transmits the detected information to the control unit. The control unit transmits a control signal to the pump P3, and the pump P3 stops. Thereafter, bubbles can be supplied by the bubble supply system. The required disinfection and sterilization time varies depending on the type of disinfectant, so in accordance with the type of disinfectant used, the disinfection and disinfection time is set in advance before the disinfection and disinfection time. The mode in which the control signal is transmitted and the alarm is generated is preferable for ensuring the sterilizing effect of the disinfecting liquid and using the disinfecting liquid for as long as possible.

  Since the disinfectant can be used a predetermined number of times depending on the type, the disinfectant until the predetermined number of times is collected and reused. When collecting the disinfectant, as shown in FIG. 2, the control unit transmits a control signal to the electromagnetic valve V4, the electromagnetic valve V4 is closed, transmits a control signal to the electromagnetic valve V3, and the electromagnetic valve V3. Opens. Moreover, a control part transmits a control signal to the pump P1, and collects disinfecting liquid in the processing tank 3 to a disinfecting liquid tank by the pump P1. When the collection of the disinfectant is completed, the sensor 11 disposed in the lower tank 9 detects and transmits detection information to the control unit, and the received control unit transmits a control signal to the pump P1, and the pump P1 stops. When the disinfecting liquid is not collected, the processing liquid (disinfecting liquid) in the processing tank 3 can be discharged by the discharge system. When the sterilization treatment is completed by collecting or discharging the disinfectant, the aspect of supplying water from the upper part of the treatment tank 3 can erase bubbles remaining in the treatment tank and reduce the malfunction of the machine. preferable.

  The number of times that the disinfectant can be used is limited depending on the type. For this reason, the number of times of sterilization / disinfection is set in advance according to the type of the disinfectant, and the control unit counts and records the number of times of sterilization / disinfection, and when the number of times of sterilization / disinfection has passed, the control unit transmits a control signal. However, a mode in which an alarm is generated is preferable. Such an embodiment can ensure a high level of sterilizing and disinfecting effects even when different disinfecting liquids are used, and can provide objectivity in the determination of recovery and discharge of the disinfecting liquids after processing. When performing sterilization a plurality of times, the supply and recovery or discharge of these disinfectants can be repeated, and after the sterilization and sterilization, rinsing and cleaning can be performed using a cleaning water supply system.

  FIG. 3 is a flowchart for carrying out the cleaning / disinfecting method by the small-diameter endoscope cleaning / disinfecting apparatus of the present invention. As illustrated in FIG. 3, first, the cleaning / disinfecting process is started, and the endoscope is placed in the cleaning / disinfecting apparatus (step S <b> 1). As for the arrangement of the endoscope, the insertion portion of the small-diameter endoscope is housed in the treatment tank of the cleaning / disinfecting apparatus, and the operation portion of the small-diameter endoscope is placed on the holding section of the cleaning / disinfecting apparatus. Next, rinsing is performed by the cleaning water supply system (step S2), and large dirt and dirt that can be removed by washing water are first removed. The rinsing is preferably performed while supplying bubbles, and can be performed a predetermined number of times, and the processing liquid is discharged after completion.

  Next, detergent cleaning is performed by the detergent liquid supply system (step S3), and the dirt component on the insertion portion surface of the endoscope is strongly removed. The detergent cleaning is preferably performed while supplying bubbles, and the processing liquid is discharged after the detergent cleaning. Subsequently, rinsing is performed (step S4), and the soil components and the detergent liquid are removed. The rinsing cleaning is also preferably performed while supplying bubbles. After the rinsing cleaning, the treatment liquid is discharged. In addition, the rinse cleaning (step S4) is performed a plurality of times as necessary.

  Thereafter, sterilization is performed by the disinfectant supply system (step S5), and the insertion part of the endoscope cleaned with the detergent is sterilized to eliminate the risk of secondary infection and the like. Sterilization / disinfection is preferably performed while supplying bubbles, and when the disinfection / sterilization is completed, the disinfectant solution is collected or discharged. Next, rinsing and cleaning are performed (step S6), and the disinfectant remaining in the insertion portion of the endoscope is removed. The rinsing cleaning is also preferably performed while supplying bubbles. After the rinsing cleaning, the treatment liquid is discharged. Further, the rinse cleaning (step S6) is performed a plurality of times as necessary. Thereby, the cleaning / disinfecting by the small-diameter endoscope cleaning / disinfecting apparatus is completed.

  FIG. 4 is a conceptual diagram showing the structure of the small-diameter endoscope cleaning / disinfecting apparatus of the present invention. FIG. 4 (a) shows the internal structure 2 to which the treatment tank 3 is connected, and FIG. The housing 1 is shown. In the example shown in FIG. 4, convex members 2 a are arranged on the left and right sides of the bottom surface of the internal structure 2, and the convex members 2 a have a long and narrow shape in the pulling direction (front direction) of the internal structure. On the other hand, L-shaped members 1a are disposed on the left and right sides of the bottom surface of the housing 1, and the L-shaped members 1a have an elongated shape in the pull-out direction (: front side). Further, during storage, adjustment is made so that the convex member 2a on the internal structure side is disposed on the L-shaped member 1a on the housing side.

  Therefore, when the internal structure 2 is stored in the housing 1, the internal structure 2 is placed on the bottom surface of the housing 1. Further, when the internal structure 2 is pulled out from the housing 1, the convex member 2a slides on the L-shaped member 1a, so that it can be pulled out manually. Providing the internal structure 2 with the convex member 2a is preferable in that the drawer and storage from the housing 1 are smooth. Further, when the L-shaped member 1a is provided in the housing 1, the convex member 2a of the internal structure 2 is guided, and therefore the internal structure 2 can be pulled out and stored from the housing 1 linearly. Adjusting the arrangement of the convex member 2a and the L-shaped member 1a is preferable in that the position of the internal structure 2 during storage can be accurately determined.

  FIG. 5 is a conceptual diagram showing the structure of the small-diameter endoscope cleaning / disinfecting apparatus of the present invention. FIG. 5 (a) shows the internal structure 2 to which the treatment tank 3 is connected, and FIG. The housing 1 is shown. In the example shown in FIG. 5, as in the example of FIG. 4, elongated convex members 2 a are disposed on the left and right on the bottom surface of the internal structure 2. On the other hand, on the left and right sides of the bottom surface of the housing 1, similarly to the example of FIG. 4, elongated L-shaped members 1a are arranged, and the convex members 2a on the internal structure side are placed on the L-shaped members 1a on the housing side when stored. Adjust to position. On the other hand, in the example shown in FIG. 5, unlike FIG. 4, the bottom surface of the housing 1 is arranged only on both the left and right sides when viewed from the direction in which the internal structure 2 is pulled out (the front direction). Also in the aspect shown in FIG. 5, when the internal structure 2 is stored in the housing 1, the internal structure 2 is placed on the bottom surface of the housing 1. Further, when the internal structure 2 is pulled out from the housing 1, the convex member 2a slides on the L-shaped member 1a, so that it can be pulled out manually, and the internal structure can be manually stored in the housing.

  FIG. 6 is a conceptual diagram showing the internal structure of the thin endoscope cleaning / disinfecting apparatus of the present invention. Since the internal structure 2 illustrated in FIG. 6 includes a pulley 13 instead of the convex member 2a in FIGS. 4 and 5, when the internal structure 2 is housed in the housing, the internal structure is placed on the bottom surface of the housing. Place it with a pulley in between. The embodiment shown in FIG. 6 is preferable in that the operability can be improved when the internal structure is manually pulled out from the casing or when the internal structure is manually stored in the casing. Also in this aspect, as shown in FIG. 4 or FIG. 5, the elongated L-shaped members 1a are arranged on the left and right sides of the bottom surface of the housing 1, and the pulley 13 on the internal structure 2 side is placed on the housing 1 side when stored. The form adjusted so that it may arrange | position on the L-shaped member 1a is preferable. When the pulley 13 is adjusted so as to be disposed on the L-shaped member 1a, the pulley 13 is guided by the L-shaped member 1a, and the internal structure can be pulled out and stored linearly.

  In the example shown in FIG. 6, since the front wheel 13a and the rear wheel 13b are arranged as the pulley 13, when the internal structure is pulled out from the housing or when the internal structure is stored in the housing, the mobility of the internal structure is high. High and good workability. However, since the mobility of the internal structure is high, there is a risk that the internal structure may inadvertently float when the internal structure is serviced after being pulled out of the housing. Therefore, in FIG. 6, the pair of rear wheels 13b is removed and only the pair of front wheels 13a is used, that is, as viewed from the direction in which the internal structure 2 is housed in the housing (the direction of the arrow in FIG. 6) A mode in which only a pair of pulleys are arranged on the right and left sides in front is preferable. In such an aspect, when the internal structure is moved, the front wheel 13a can be moved smoothly. During maintenance inspection after the internal structure is pulled out, the internal structure 2 is fixed by the bottom portion 2b, and the internal structure does not move. Maintenance workability can be improved.

  FIG. 7 is a diagram schematically illustrating another aspect of the piping system of the small-diameter endoscope cleaning / disinfecting apparatus of the present invention. The thin endoscope illustrated in FIG. 7 includes an insertion portion 6 that is inserted into an affected area and an operation portion 7 that operates the insertion portion 6 in diagnosis and treatment of a patient. The operation portion 7 includes a suction port 15 and forceps. It is a treatment endoscope arranged by the mouth 16. The suction port 15 disposed in the operation unit 7 is used when sucking mucus or the like from the distal end of the insertion unit 6 during treatment. The forceps port 16 is used when a treatment tool used for collecting a tissue or removing a foreign substance is taken in and out. The treatment tool is disposed from the forceps port 16 through the inside of the insertion portion 6, and the tip of the insertion portion is used for the tissue. Collect and so on. For this reason, it is essential to clean and disinfect the inside of the insertion portion 6 including the suction port 15 and the forceps port 16 after the treatment.

  As illustrated in FIG. 7, when rinsing and cleaning the inside of the suction port 15, the forceps port 16, and the insertion portion 6, the control unit transmits a control signal to the pump P 5 simultaneously with rinsing and cleaning outside the insertion portion 6. Then, the pump P5 sends cleaning water and bubbles from the outlet 14 of the processing tank 3 to the suction port 15 and the forceps port 16. Therefore, by supplying cleaning water and bubbles in the processing tank through the suction port and forceps port in the operation unit, the inside of the endoscope is rinsed and cleaned simultaneously with the rinsing and cleaning of the outside of the insertion portion of the endoscope. be able to.
