Next, the non-contact power transmission / reception unit 55 of the endoscope cleaning / disinfecting apparatus 2 and the battery unit 150 of the endoscope body 101 will be described in detail with reference to FIG.
As shown in FIG. 9, the non-contact power transmission / reception unit 55 includes an AC input 56, an EMI (Electro Magnetic Interference) filter that is a noise filter, a rectification / smoothing circuit 58, a charge control circuit 59, and a device-side magnet 55b. And built-in. The charge control circuit 59 is connected to the device-side magnet switch 59a and the transmission / reception coil 55a.

  As shown in FIG. 9, the battery unit 150 includes a power supply circuit 151A that is a battery power supply control means including a switching control circuit 151a and a charging circuit 151b, and a battery-side magnet 150b. The power circuit 151A is connected to the battery-side magnet switch 150a. In the state where the scope connector part 105a of the endoscope body 101 is set in the pipe line / leakage connector 37 of the washing tub 4, the position where the apparatus side magnet switch 59a and the battery side magnet 150b correspond, the battery side magnet The switch 150a and the device-side magnet 55b are respectively arranged at corresponding positions.

  The charging control circuit 59 of the non-contact power transmission / reception unit 55 receives the magnetic force when the battery side magnet 150b of the battery unit 150 approaches, and the device side magnet switch 59a is operated. The charge control circuit 59 that has received the ON signal from the device-side magnet switch 59a supplies the power from the AC input 56 to the transmission / reception coil 55a. The power supplied to the transmission / reception coil 55a is electromagnetically coupled to the transmission / reception coil 151 of the battery unit 150 and the transmission / reception coil 55a of the non-contact power transmission / reception unit 55, and is supplied to the transmission / reception coil 151 in a non-contact manner. Thus, the power of the transmission / reception coil 151 is supplied to the power supply circuit 151A by electromagnetic induction.

  Further, the switching control circuit 151a of the power supply circuit 151A receives the magnetic force when the battery-side magnet switch 150a comes close to the device-side magnet 55b of the non-contact power transmission / reception unit 55, and the battery-side magnet switch 150a operates. The switching control circuit 151 a that has received the ON signal from the battery-side magnet switch 150 a performs switching control of whether to perform a charging operation or to supply power to the endoscope body 101 based on the stored voltage of the battery unit 150.

  The monitor 26 displays information related to the cleaning and disinfection of the endoscope body 101 such as the cleaning / disinfection remaining time as well as the endoscope image and scope individual information. The operation panel 25 is provided with various setting switches such as a mode selection switch in addition to the start switch.

Next, an operation of cleaning and disinfecting the endoscope body 101 by the endoscope cleaning / disinfecting system of the present embodiment configured as described above will be described.
After the end of the endoscopic examination, the user removes the universal cord 103 from the endoscope main body 101 of the endoscope 100. This universal code 103 is disposed of in a predetermined manner. Next, the user performs simple preliminary cleaning on the endoscope main body 101 at the bedside where the patient has been laid down. Then, the user performs the main cleaning of the endoscope at the sink. In this way, the endoscope main body 101 thus cleaned is set in the cleaning tank 4 of the endoscope cleaning / disinfecting apparatus 2.

  First, the user opens the cleaning cover 5 of the endoscope cleaning / disinfecting apparatus 2 and sets the endoscope main body 101 in the cleaning tank 4 provided on the upper surface of the apparatus main body. A holding net (not shown) is laid on the bottom surface of the housing recess 4 a of the cleaning / disinfecting tank 4.

  At this time, the user causes the scope connector portion 105 a of the endoscope main body 101 to face the conduit / leakage connector 37 provided on the wall surface of the washing tub 4. The pipe line / leakage detection connector 37 basically has the same configuration as the cord side connector portion 103a of the universal cord 103, and has a structure that can be joined to each other.

  Then, the user sets the endoscope main body 101 in the cleaning tub 4 in a predetermined manner, sets various programs for cleaning and disinfecting the endoscope main body 101 using the operation panel, and turns on the power switch. Then, power is turned on to the control circuit 46 built in the apparatus main body 3, and the endoscope cleaning / disinfecting apparatus 2 starts cleaning / disinfecting the endoscope main body 101.

Next, various steps of the endoscope cleaning / disinfecting apparatus 2 will be described with reference to the flowcharts of FIGS.
In step S1 shown in FIG. 10, the input of the start switch is awaited, and when the start switch is turned on, the process proceeds to step S2.

  In step S2, the electromagnet unit 51 provided in the pipe line / leakage detection connector 37 is energized, and the electromagnet unit 51 is excited. That is, the scope connector portion 105 a of the endoscope body 101 is attracted to and connected to the pipe line / leakage detection connector 37 by the magnetic force generated in the electromagnet unit 51. Then, the pipe caps 106a to 109a provided in the scope connector portion 105a and the caps 56a to 59a provided in the pipe / leakage connector 37 are automatically joined.

  Therefore, in this embodiment, when the user sets the endoscope main body 101 in the cleaning tub 4, each of the pipes 106 to 109 of the endoscope main body and the cleaning / disinfecting tube on the endoscope cleaning / disinfecting apparatus 2 side are provided. There is no need to connect the road with a tube or the like. Therefore, the time required for connecting a tube or the like can be greatly shortened, and tube connection mistakes and connection failures do not occur, and each of the ducts 106 to 109 of the endoscope main body 101 and the endoscope cleaning and disinfecting apparatus 2 are surely made. It can be connected to each side cleaning and disinfecting pipeline.

  In step S2, charging of the battery unit 150 provided in the endoscope main body 101 is started. Electric power is supplied from the non-contact power transmission / reception unit 55 of the washing tub 4 to the battery unit 150 of the endoscope body 101 in a non-contact manner. That is, power is supplied from the transmission / reception coil 55 a of the non-contact power transmission / reception unit 55 to the transmission / reception coil 151 of the battery unit 150 by electromagnetic induction. Specifically, the charging control circuit 59 of the non-contact power transmission / reception unit 55 receives the magnetic force when the battery side magnet 150b of the battery unit 150 approaches, and the device side magnet switch 59a operates. The power supplied to the transmission / reception coil 55a is electromagnetically coupled to the transmission / reception coil 151 of the battery unit 150 and the transmission / reception coil 55a of the non-contact power transmission / reception unit 55, and is supplied to the transmission / reception coil 151 in a non-contact manner. Thus, the power of the transmission / reception coil 151 is supplied to the power supply circuit 151A by electromagnetic induction. At this time, the switching control circuit 151a of the power supply circuit 151A receives the magnetic force when the battery side magnet switch 150a comes close to the device side magnet 55b of the non-contact power transmission / reception unit 55, and the battery side magnet switch 150a operates. The switching control circuit 151 a performs switching control of whether to perform a charging operation or to supply power to the interior of the endoscope body 101 based on the storage voltage of the battery unit 150. This charging operation is continued until the switching control circuit 151a determines that the predetermined storage voltage value is maintained.

  Therefore, since the built-in battery unit 150 is charged while the endoscope main body 101 is cleaned and disinfected, the user does not have to perform various operations for the charging operation. Therefore, the time required for charging the battery unit 150 can be reduced.

  Next, the process proceeds to step S4, and the switching control circuit 151a of the battery unit 150 enables the power of the endoscope body 101 with a predetermined frequency. Then, the endoscope side control circuit 112 and the control circuit 46 built in the apparatus main body 3 can communicate with each other wirelessly by the transmission / reception antenna 115 of the endoscope main body 101 and the apparatus side transmission / reception antenna 52 provided in the washing tub 4. It becomes.

  Next, the process proceeds to step S5, and the scope individual information such as the model number of the endoscope main body 101 stored in the memory element of the endoscope side control circuit 112, various history information such as the repair history, the number of times of washing, etc. 115 and the device-side transmitting / receiving antenna 52 are read by wireless communication and stored in the scope memory R / W circuit 63 via the control circuit 46 provided in the device body 3.

  Then, it progresses to step S6 and opens the water supply valve 14A and starts water supply from a water tap. When starting the water supply, first, the three-way switching valve 29 is operated to connect the water supply / circulation nozzle 24 to the water filter 14 side. Then, the tap water filtered by the water filter 14 is supplied from the water supply / circulation nozzle 24 to the cleaning / disinfecting tank 4. In step S7, the water level in the washing / disinfecting tank 4 is detected by a water level sensor (not shown), and the end time of water supply is monitored. When the water level stored in the washing / disinfecting tank 4 reaches the set water level, the three-way switching valve 29 is operated again, the connection between the water supply / circulation nozzle 24 and the water filter 14 is cut off, and the water supply is terminated. The process proceeds to step S8.

  In step S8, various functions of the endoscope main body 101 are checked. Function check items include basic items and model-specific items. The basic items are items that are uniformly executed regardless of the model of the endoscope main body 101 to be cleaned and disinfected. On the other hand, the model-specific items are set for each endoscope 100 based on the read model number. The check item corresponding to is automatically set. As basic items, there are, for example, a water leakage check and a pipe clogging check.

  In the water leakage check, first, the shutoff valve 40 built in the apparatus body 3 is opened, and the air from the water leakage detection pump 39 is joined to the apparatus side water leakage detection base 53 shown in FIG. The inside of the endoscope main body 101 is pressurized by being supplied into the endoscope main body 101 from the water leak detection base 118 provided in the scope connector portion 105a of the main body 101. When the predetermined pressure is reached, the shutoff valve 40 is closed and the pressure change in the endoscope body 101 is measured. If the pressure change at this time is large, it is determined that a hole is formed in the outer surface of the endoscope body 101 and air is leaking. If the pressure change is small, it is determined to be normal.

  In order to check the clogging of the pipe line, first, the CH block 31 is operated to connect the circulation port 21 opened in the cleaning / disinfecting tank 4 to the pipe line / leakage detection connector 37, and by driving the CH pump 32, The tap water stored in the cleaning / disinfecting tank 4 is supplied to the conduit / leakage connector 37. And tap water is supplied to each pipe line 106-109 of the endoscope main body 101 via the pipe line / leakage connector 37, and the tap water is circulated. And the flow volume of the tap water which distribute | circulates the inside of each pipe line 106-109 at this time is measured by the pipe line sensor 121, The value and a reference value are compared, When a flow volume is below a reference value, a pipe line Judge as clogged. On the other hand, when the flow rate is equal to or higher than the reference value, it is determined as normal.

  On the other hand, the model-specific items differ for each model. For example, in the case where the illumination element 111 is provided at the distal end of the endoscope main body 101 as illumination means as in this embodiment, the illumination element 111 is changed from the endoscope side control circuit 112. The driving signal for illumination is output to the monitor 26, and the endoscopic image at that time is displayed on the monitor 26. The user checks whether or not the illumination element 111 is lit based on the brightness of the endoscopic image of the monitor 26. In this case, although it is an artificial determination, whether or not the light emitting element is turned on may be automatically detected by comparing the amount of light received by the image sensor 110 with a reference value, for example. Further, in the endoscope main body 101 in which the distal end portion of the endoscope insertion portion 105 is bent by the EPAM angle member 105B, an angle operation signal is output from the endoscope side control circuit 112 to the angle member 105B. The endoscopic image at that time is displayed on the monitor 26. The user checks whether the endoscope image is operating normally depending on whether the endoscope image is moving. In this case as well, although it is an artificial determination, for example, continuous movement of an image in a specific pixel region of an endoscopic image captured by the image sensor 110 is detected, and this movement and a drive signal output to the angle member 105B are detected. And whether or not the angle member 105B is normal may be automatically checked based on whether or not it substantially corresponds.

  Further, the control circuit 46 determines charging pressure information from the power supply circuit 151A of the battery unit 150 built in the endoscope main body 101, and checks whether or not the battery charging is completed.

  Then, the process proceeds to step S9, and if it is determined that any one of the functions is abnormal as a result of the function check, the process branches to step S10, and the monitor 26 displays on the monitor 26 that the endoscope body 101 is abnormal. Then, the process proceeds to step S11, and the cleaning / disinfecting process of the endoscope cleaning / disinfecting apparatus 2 is stopped. In this case, the user can easily determine that an abnormality has occurred in the endoscope main body 101, and can make a repair request by reporting the state of the abnormal part to the manufacturing company.

  On the other hand, when it is determined that all of the function check items are normal, the process proceeds to step S12 shown in FIG. 11 and the washing process is started. In the present embodiment, since the automatic operation is performed, the cleaning cover 5 is closed.

  When the washing process is started, first, an appropriate amount of liquid detergent stored in the detergent tank 11 is discharged from the detergent nozzle 22 by driving the detergent pump 27 and mixed with tap water stored in the washing / disinfecting tank 4. Wash water is generated. In the cleaning process, the cleaning water stored in the cleaning / disinfecting tank 4 is ejected from the high-pressure nozzle 19 provided on the outer peripheral wall surface of the housing recess 4a and the inner peripheral wall surface of the endoscope body 101, and the inside of the cleaning / disinfecting tank 4 A water stream is generated. Further, this water flow is vibrated by driving the ultrasonic vibrator 6. As a result, the outer surface of the endoscope body 101 is washed by the washing water flow and vibration.

  Further, the three-way switching valve 29 and the CH block 31 are operated so that the circulation port 21, the water supply / circulation nozzle 24, and the pipe line / leakage detection connector 37 communicate with each other. As a result, the wash water is discharged from the water supply / circulation nozzle 24 by the driving of the fluid pump 30 and circulated. At the same time, the cleaning water is supplied to each of the pipes 106 to 109 of the endoscope main body 101 by the discharge pressure of the CH pump 32 via the pipe / leakage detection connector 37, and the inside of each of the pipes 106 to 109 is washed. .

  Since the pipes 106 to 109 of the endoscope main body 101 employed in the present embodiment do not include a valve or a mechanism for operating the valves, the pipes 106 to 109 are piped in a substantially straight shape. The washing water can flow smoothly, and the inside of each of the pipes 106 to 109 is washed evenly.

  Then, the process proceeds to step S13, where it is determined whether or not the cleaning process has been completed based on whether or not the set time has been reached, and the cleaning process is continued until the set time is reached. Then, when the set time is reached, it is determined that the washing has been completed, and the process proceeds to step S14 where the washing water is drained. For the drainage of the washing water, the switching valve 43 provided at the drain opening 42 opened at the bottom of the washing / disinfecting tank 4 is operated to connect the drain opening 42 and the external drain opening 82 to drive the drain pump 44. Forcibly drain.

  When the drainage is completed in a predetermined manner, the switching valve 43 is operated to close the drainage port 42, and the three-way switching valve 29 is further operated to shut off the circulation port 21 and the water supply / circulation nozzle 24, and then step S15. And the disinfection process is started.

  When the disinfecting process is started, first, the disinfecting liquid stored in the disinfecting liquid tank 12 is supplied to the disinfecting liquid nozzle 23 by driving the chemical liquid pump 28, and the disinfecting liquid is supplied from the disinfecting liquid nozzle 23 to the washing tank 4. Is supplied. In this state, the circulation port 21 and the pipe line / leakage connector 37 are in communication with each other, so that the disinfecting liquid stored in the washing tub 4 is driven by the CH pump 32 so that It injects into the pipe lines 106-109. Then, after the water level of the disinfecting liquid supplied to the cleaning / disinfecting tank 4 reaches the set water level, the disinfecting liquid is circulated for a set time.

  Thereafter, when the set time is reached, the driving of the CH pump 32 is stopped, and the endoscope main body 101 is immersed in the disinfectant for the set time. Also in this case, since each of the pipes 106 to 109 of the endoscope main body 101 according to the present embodiment is piped in a substantially straight shape, the disinfecting liquid spreads uniformly throughout the pipe.

  Next, in step S16, the immersion time of the endoscope main body 101 is measured. When the immersion time reaches the set time, it is determined that the disinfection is completed, and the process proceeds to step S17. In step S17, the disinfectant is collected. Since the disinfecting liquid is repeatedly used a certain number of times, the switching valve 43 is operated, the drain port 42 is communicated with the disinfecting liquid tank 12, and the disinfecting liquid stored in the cleaning / disinfecting tank 4 is stored in the disinfecting liquid tank 12. To be recovered.

  After the disinfecting liquid is collected in the disinfecting liquid tank 12 in a predetermined manner, the process proceeds to step S18, and the rinsing process is started. When the rinsing process is started, first, the three-way switching valve 29 is driven, the water / circulation nozzle 24 is communicated with the water filter 14 side, and the tap water filtered by the water filter 14 from the water / circulation nozzle 24 is washed in the washing tank. 4 is supplied. Then, after the tap water reaches a predetermined water level, the three-way switching valve 29 is closed, and the tap water stored in the cleaning / disinfecting tank 4 is circulated as in the cleaning process. Then, after the set time has elapsed, the water is drained.

  In step S19, the number of times of rinsing N is counted, and when the number of times of rinsing N reaches the set number of times, it is determined that the rinsing process is finished. And after the tap water used in the last rinse process is drained predetermined, it progresses to step S20 and an air supply process is started. When the air supply process is started, the CH block 31 is driven, the compressor 34 and the pipe line / leakage connector 37 are communicated, and compressed air is sent to the pipe lines 106 to 109 of the endoscope body 101. Ventilate, and drain and dry the inside of each of the pipes 106-109.

  In step S21, the air supply time by the compressor 34 is counted, and when the set time is reached, it is determined that the air supply process is finished, and after the compressor 34 is stopped, the process proceeds to step S22.

  In step S22, an alcohol flush process is started. In the alcohol flushing process, first, the CH block 31 is driven to connect the alcohol tank 13 and the conduit / leakage connector 37, and the alcohol pump 13A is driven to drive a small amount of alcohol stored in the alcohol tank 13. Only the liquid is sent to the pipes 106 to 109 of the endoscope main body 101. Next, the CH block 31 is driven again, the pipe line / leakage detection connector 37 is communicated with the compressor 34, and the compressed air is supplied to the pipe lines 106 to 109 of the endoscope main body 101 by driving the compressor 34. The

  Alcohol is supplied to the pipelines 106 to 109 of the endoscope main body 101 together with the compressed air, and the alcohol promotes the evaporation of a slight amount of water remaining in the pipelines 106 to 109, and the pipelines 106 to 109. The inside is dried early.

  In step S23, the compressed air feeding time is counted, and when the set time is reached, it is determined that the alcohol flush process is finished, and all the processes are finished.

  As described above, in this embodiment, when cleaning and disinfecting the used endoscope body 101, the scope connector portion 105a formed on the endoscope body 101 is connected to the conduit / leakage connector 37 of the apparatus body 3. Since the connection can be completed by mounting with one touch, a complicated connection work becomes unnecessary, and the work efficiency can be improved. In addition, since the work efficiency is improved, the time required for cleaning and disinfection is shortened, and the operation efficiency of the endoscope 100 can be improved correspondingly. Furthermore, since the endoscope main body 101 and the apparatus main body 3 are all non-contact types except for the portions where the pipes 106 to 109 and the water leak detection base 118 are joined, washing water during washing and disinfection, A liquid such as a disinfectant does not enter the endoscope main body 101, and a good waterproof property can be obtained.

  By the way, in the various function checks executed in step S8 before the cleaning / disinfecting process of the endoscope main body 101 by the endoscope cleaning / disinfecting apparatus 2 shown in FIG. 10, the model-specific items are also checked in addition to the basic items. However, the model-specific item may be performed in the background during a series of processing steps from the washing step to the disinfection step.

  FIG. 12 shows an example of various function check steps of the endoscope main body 101 executed in the background.

  In this step, first, in step S31, an angle operation check of the tip portion operated by the angle member 105B is performed. In checking the angle operation, an angle operation signal is output from the endoscope side control circuit 112 to the angle member 105B, and the endoscope image at that time is displayed on the monitor 26, and whether or not the endoscope image is moving. Check if it works properly.

  In step S <b> 32, a lighting signal is output from the endoscope side control circuit 112 to the illumination element 111, and the endoscope image at that time is displayed on the monitor 26. The user checks whether a predetermined brightness is obtained by the monitor 26. In step S33, the user checks the endoscopic image displayed on the monitor 26 and checks whether the image sensor 110 is operating normally.

  Furthermore, in step S34, the information signal of the charging pressure value of the battery unit 150 built in the endoscope body 101 is output from the power supply circuit 151A, and the predetermined charging pressure value is determined by the control circuit 46. Check if battery charging is complete. When a predetermined battery charging pressure value is detected, the process proceeds to step S35 as it is.

  Here, when the predetermined charging pressure value of the battery unit 150 of the endoscope main body 101 is not detected, the charging operation to the battery unit 150 is performed until the predetermined charging pressure value is detected. When a predetermined battery charging pressure value is detected by the control circuit 46, the process proceeds to step S35.

  In step S35, when it is determined that all operations are normal, the various function checks are terminated as they are. On the other hand, if at least one abnormality is detected, the process branches to step S36, notifies the abnormality, then proceeds to step S37, and waits for an input as to whether or not to stop the current processing step. When the processing process is not stopped, the various function checks are finished as they are. On the other hand, when stopping a process, it progresses to step S37, the present process is stopped, and various function checks are complete | finished.

  Thus, the model-specific item of the endoscope main body 101 can be performed as a background during each processing step of the endoscope cleaning / disinfecting apparatus 2, and the battery unit 150 of the endoscope main body 101 is charged. Checking and battery charging operation can be performed during each processing step. Therefore, it is not necessary to perform the battery charging operation with the endoscope main body 101 alone. As a result, the time required for cleaning and disinfecting the endoscope main body 101 can be further shortened, and the operating efficiency of the endoscope 100 can be relatively improved.
