FIG. 7 is a partial cross-sectional view showing the contact state of the endoscope with the top cover when the top cover showing the operation of the present embodiment is closed to the apparatus main body, and FIG. It is a fragmentary sectional view which shows the contact state of the endoscope with respect to a top cover at the time of closing.

  When the endoscopes 100 and 110 after use are washed and disinfected, as shown in FIG. 3, for example, first, the operation of the endoscope 110 is performed on the holding net 60 disposed in the tank body 50 of the washing and disinfecting tank 4. The portion 111 is placed on the holding net 60 on the side where the ports 33 to 35 are disposed, and the insertion portion 112 and the universal cord 113 are placed in the washing case 6 at the approximate center of the tank body 50 in the holding net 60. Then, it is wound around the water supply line disinfection port 7 and placed.

  Next, the operation unit 101 of the endoscope 100 is placed on the holding net 60 on the side where the ports 33 to 35 are disposed, and the insertion unit 102 and the universal cord 103 are placed on the tank body 50 in the holding net 60. In the approximate center, it is wound around and placed around the cleaning case 6 and the water supply line disinfection port 7.

  At this time, since the tank body 50 is formed to a minimum size necessary for cleaning and disinfection, a part of the operation unit 111 of the endoscope 110 is superimposed on the operation unit 101 of the endoscope 100. To be placed.

  In addition, a part of the insertion portion 112 and the universal cord 113 of the endoscope 110 is disposed so as to be superimposed on the insertion portion 102 or the universal cord 103 of the endoscope 100. Alternatively, the insertion portion 112 is disposed so as to be superimposed on the universal code 113. Alternatively, the insertion unit 102 is arranged so as to be superimposed on the universal code 103.

  Thereafter, as shown in FIG. 3, the inflow side connection port 150c is connected to the air / water supply / forceps port 33a, and the outflow side is bifurcated, for example, the outflow side connection of the Y-shaped branch tube 150 The port 150 a is connected to a pipe connection port 98 on the outer surface of the operation unit 101 of the air / water supply pipe disposed inside the endoscope 100.

  Further, the conduit connection port 99 on the outer surface of the operation portion 101 of the treatment instrument insertion conduit that also serves as the suction conduit disposed inside the endoscope 100 by using the outflow side connection port 150 b of the branch tube 150. Connect to.

  Further, the inflow side connection port 151c is connected to the air / water supply / forceps port 33b, and the outflow side branch port 151a of the Y-shaped branch tube 151 having the outflow side branched into two branches is used for the endoscope. 110 is connected to a pipe connection port 198 on the outer surface of the operation unit 111 of the air / water supply pipe arranged in 110.

  Further, the outflow side connection port 151b of the branch tube 151 serves as a suction tube disposed inside the endoscope 110, and the conduit connection port 199 on the outer surface of the operation unit 111 of the treatment instrument insertion conduit. Connect to.

  When the endoscopes 100 and 110 each have a secondary water supply / forceps raising conduit 34, the other end of the washing tube having one end connected to the secondary water supply / forceps raising port 34a is connected to the endoscope 100, 110. Connect to the pipe connection port of the sub-water supply / forceps raising pipe of the endoscope 100. Further, the other end of the washing tube having one end connected to the auxiliary water / forceps raising port 34 b is connected to the pipe connection port of the auxiliary water supply / forceps raising port of the endoscope 110.

  Further, as shown in FIG. 3, the other end of the washing tube, one end of which is connected to one of the water leak detection ports 35, is connected to the water leak detection connection port 97 of the endoscope 100, and the other water leak detection is detected. The other end of the cleaning tube having one end connected to the service port 35 is connected to a water leak detection connection port 197 of the endoscope 110.

  Next, as shown in FIG. 1, the top cover 3 is closed with respect to the apparatus main body 2, whereby the endoscope housing port 2 s of the tank body 50 of the cleaning / disinfecting tank 4 is closed by the top cover 3.

  At this time, for example, when the outer surface of the universal cord 113 of the endoscope 110 is in contact with the inner surface 3n, the inner surface 3n of the top cover 3 is one of the plurality of convex portions 70 formed on the inner surface 3n. Only the convex portion 70 makes point contact, line contact, or surface contact with the contact portion 90 on the outer surface of the universal cord 113.

  As a result, as shown in FIG. 7, a gap 91 is formed between the inner surface 3 n of the top cover 3 and the outer surface of the contact portion 90 of the universal cord 113 by the convex portion 70 that contacts the contact portion 90. The

  After that, when the endoscope cleaning / disinfecting process is started, the cleaning / disinfecting tank 4 is fully filled with the cleaning liquid and the outer surfaces of the endoscopes 100 and 110 and the inside of the pipelines are cleaned. The sterilizing solution is filled to the full, and the outer surfaces of the endoscopes 100 and 110 and the inside of the pipelines are sterilized. Since this washing process or disinfection process is well known, detailed description thereof is omitted.

  Here, when the endoscope is cleaned or disinfected, in the endoscope apparatus in which the inner surface 3n of the top cover 3 as shown in FIG. 8 is formed in a plane, the contact between the inner surface 3n and the contact portion 90 is made. The area becomes large, and it is difficult to cleanse or disinfect the outer surface of the contact part 90 reliably because the cleaning liquid or the disinfecting liquid cannot be introduced between the inner surface 3n and the contact part 90.

  However, in the present embodiment, only the convex portion 70 formed on the inner surface 3n of the top cover 3 contacts the contact portion 90 of the universal cord 113, and the contact area between the inner surface 3n and the contact portion 90 is as shown in FIG. 8 is significantly smaller than the conventional one shown in FIG. 8, the cleaning liquid or the disinfecting liquid is used for cleaning or disinfecting the gap 91 between the inner surface 3 n of the top cover 3 formed by the convex portion 70 and the universal cord 113. The outer surface of the universal cord 113 facing the gap is surely cleaned or disinfected.

  Moreover, since the convex part 70 and the contact part 90 are contacting with the minimum contact area, the washing | cleaning liquid or disinfection liquid inject | poured into the gap | interval 91 is made to enter between the convex part 70 and the contact part 90. It is also possible.

  This is not limited to the case where the universal cord 113 is in contact with the inner surface 3n of the top cover 3, and the same applies to the case where the universal cord 103 and the insertion portions 102 and 112 are in contact.

  In addition, since the operation in the cleaning or disinfection process using other endoscope cleaning / disinfecting apparatuses is well known, the description thereof is omitted.

  Thus, in the present embodiment, a plurality of rail-shaped convex portions 70 having a hemispherical cross section, for example, are formed on the inner surface 3n of the top cover 3 in a radial pattern on the top cover 3. It was shown that it was formed integrally with the inner surface.

  The plurality of convex portions 70 of the endoscopes 100 and 110 wound around and placed on the holding net 60 of the cleaning / disinfecting tank 4 when the top cover 3 is closed with respect to the apparatus main body 2. For example, it has been shown that it is formed at the position of the inner surface 3n of the top cover 3 facing the insertion portions 102 and 112 and the universal cords 103 and 113, respectively.

  According to this, when the endoscopes 100 and 110 are not correctly set on the holding net 60 of the cleaning / disinfecting tank 4 and the top cover 3 is closed with respect to the apparatus main body 2, the inner surface of the top cover 3. Even if 3n comes into contact with the contact portion 90 of the endoscope, the contact portion 90 of the endoscope comes into contact with only one of the plurality of convex portions 70 formed on the inner surface 3n of the top cover 3. Since the contact is minimal, the contact portion 90 that contacts the inner surface 3n of the endoscope can be surely cleaned and disinfected.

  Thus, the setting of the endoscopes 100 and 110 with respect to the cleaning / disinfecting tank 4 can be improved with a simple configuration in which only the convex portion 70 is provided on the inner surface 3n of the top cover 3, and the internal The endoscopes 100 and 110 can be cleaned and disinfected.

  A modification will be described below. In the present embodiment, the configuration, operation, and the like that minimize the contact area between the inner surface 3n of the top cover 3 and the contact portion 90 of the endoscope when the two endoscopes 100 and 110 are cleaned and disinfected. Although the effect has been described, it goes without saying that the same effect can be obtained even when one endoscope is washed and disinfected.

  Further, in the present embodiment, the two endoscopes 100 and 110 are exemplified as the case where they are placed on the holding net 60. However, the present invention is not limited to this, and the holding net 60 is not used. Even when the endoscopes 100 and 110 are accommodated directly in the cleaning / disinfecting tank 4, the same effects as in the present embodiment can be obtained.

  Another modification will be described below. FIG. 9 is a partial cross-sectional view showing a contact state of the endoscope with respect to the top cover in a modification in which a plurality of recesses are provided on the inner surface of the top cover in FIG.

  In the present embodiment, a plurality of rail-like convex portions 70 having, for example, a hemispherical cross section are integrally formed with the inner surface 3n of the top cover 3 on the inner surface 3n of the top cover 3 in a radial pattern. It was shown that it was formed.

  Not limited to this, as shown in FIG. 9, a plurality of rail-shaped concave grooves 71 are formed on the inner surface 3 n of the top cover 3 in a radial pattern on the plane, like the convex section 70 described above. However, the contact area between the inner surface 3n of the top cover 3 and the contact portion 90 on the outer surface of the universal cord 113 of the endoscope 110, for example, is minimized, and the concave groove 71 causes the top cover 3 to Since the gap 91 is formed between the inner surface 3n and the outer surface facing the concave groove 71 of the universal cord 113, the same effect as in the present embodiment can be obtained. This also applies to the endoscope 100, and the same applies to the case where the two endoscopes 100 and 110 are cleaned and disinfected.

  Further, in this case, the groove 71 constitutes a gap forming member provided between the inner surface 3n of the top cover 3 and the endoscope 100 or the endoscope 110 in the present invention.

(Second Embodiment)
FIG. 10 is a top view of the endoscope insertion portion, the universal cord, and the top cover as viewed from above the top cover when the top cover of the endoscope cleaning / disinfecting apparatus according to the present embodiment is closed to the apparatus main body. FIG. 11 is a cross-sectional view of the top cover along the line XI-XI in FIG. 10.

  In the present embodiment, as compared with the first embodiment described above, a plurality of convex portions 70 or concave grooves 71 are provided on the inner surface 3n of the top cover 3 so that the contact portion 90 on the outer surface of the endoscope is the same. The only difference is that it is formed only in a preset area that contacts. Therefore, only this difference will be described, the same reference numerals are given to the same components as those in the first embodiment, and the description thereof will be omitted.

  By the way, when the endoscope is placed on the holding net 60 of the cleaning / disinfecting tank 4 and the top cover 3 is closed with respect to the apparatus main body 2, the number of endoscopes placed on the holding net 60 is one. Even if there are two, the portion where the endoscope insertion portion and the universal cord overlap and intersect with each other becomes a contact portion and can easily come into contact with the inner surface 3n of the top cover 3.

  Specifically, as shown in FIG. 10, for example, a portion where the endoscope insertion portion 112 and the universal cord 113 of the endoscope 110 overlap and intersect each other serves as a contact portion 90 and the inner surface 3n of the top cover 3. It becomes easy to touch.

  Further, when the holding net 60 is used, for example, when the endoscope 110 is placed on the holding net 60 and the top cover 3 is closed with respect to the apparatus main body 2, the endoscope insertion portion 112 of the endoscope 110 is A portion where the universal cord 113 overlaps, that is, a contact portion 90 that contacts the inner surface 3n of the top cover 3 is uniquely set as a region 95 shown in FIG. The

  Therefore, in the present embodiment, the plurality of convex portions 70 are formed only in the above-described preset region 95 on the inner surface 3n of the top cover 3.

  According to this, since the number of the convex portions 70 formed on the inner surface 3n of the top cover 3 is reduced as compared with the above-described embodiment, the washing / disinfecting tank is less expensive than the above-described first embodiment. 4 can improve the setting of the endoscope 110 with respect to 4, and can provide an endoscope cleaning / disinfecting apparatus that can reliably clean and disinfect the endoscope 110.

  This is the same even when the contact portion 90 of the endoscope 100 contacts the inner surface 3n of the top cover 3, and each contact portion 90 of the two endoscopes 100 and 110 is the top cover. The same applies to the case of contacting the inner surface 3n of 3.

  In addition, this is not limited to the plurality of convex portions 70, and even if the plurality of concave grooves 71 shown in FIG. 9 described above are formed only in the predetermined region 95 on the inner surface 3 n of the top cover 3, The same effect as in the case of the unit 70 can be obtained.

  Further, in the case of the concave groove, the diameter of the predetermined area 95 of the inner surface 3n of the top cover 3 is larger than the diameter of the universal cord 113 or the insertion portion 112 of the endoscope 110 as shown in FIG. If the concave groove 171 that is deeper than the above-described concave groove 71 is formed, the portion where the endoscope insertion portion 112 and the universal cord 113 intersect with each other by the concave groove 171 overlaps with the top cover 3. Since the inner surface 3n is not in contact with the gap 191, an endoscope cleaning / disinfecting apparatus capable of cleaning and disinfecting the endoscope 110 more reliably can be provided. In this case as well, the concave groove 171 constitutes a gap forming member provided between the inner surface 3n of the top cover 3 and the endoscope 100 or the endoscope 110 in the present invention.

  Here, if the concave groove 171 is formed on the entire inner surface 3n of the top cover 3, it is possible to surely prevent contact between the inner surface 3n and the outer surface of the endoscope 110, but usually the endoscope is washed. When disinfecting, since the cleaning liquid or the disinfecting liquid also cleans and disinfects the inner surface 3n, an amount that fills the cleaning / disinfecting tank 4 is injected into the cleaning / disinfecting tank 4, so that the concave groove 171 is filled over the entire surface. If formed, the height of the inner surface 3n from the bottom surface 50t of the tank body 50 is increased, the amount of the cleaning liquid or the disinfecting liquid to be used is increased, and the process time of the cleaning / disinfecting process is increased.

  Further, since the height of the inner surface 3n from the bottom surface 50t of the tank body 50 can be increased, the possibility of contact between the inner surface 3n and the outer surface of the endoscope 110 can be reduced. Depending on the setting of the endoscope 110, as shown in FIG. 8 described above, the contact area between the inner surface 3n and the contact portion 90 may be increased.

  Also from this, it is preferable that the large-diameter concave groove 171 is formed only in the preset region 95 of the inner surface 3n of the top cover 3.

  The above is the same even when the contact portion 90 of the endoscope 100 is in contact with the inner surface 3n of the top cover 3, and each contact portion 90 of the two endoscopes 100 and 110 is the top. The same applies to the case of contacting the inner surface 3n of the cover 3.

(Third embodiment)
FIG. 12 is a diagram showing the shape of the groove formed in the top cover of the endoscope cleaning apparatus of the present embodiment, and FIG. 13 is a cross-sectional view taken along line XIII-XIII in FIG. It is sectional drawing shown with a part and a universal cord.

  Note that this embodiment is different from the second embodiment described above in that the insertion grooves 102, 112 of the endoscopes 100, 110 in which the concave grooves are wound around the holding net 60 and placed thereon are mounted. The only difference is that the universal cords 103 and 113 are formed on the inner surface 3n of the top cover 3 substantially along the winding shape of the universal cords 103 and 113. Therefore, only this difference will be described, the same reference numerals are given to the same components as those in the second embodiment, and the description thereof will be omitted.

  As shown in FIG. 12, the concave groove 271 that is a concave portion is held on the inner surface 3 n of the top cover 3 so as to have a larger diameter than the insertion portions 102 and 112 of the endoscopes 100 and 110 or the universal cords 103 and 113. The insertion portions 102 and 112 placed on the net 60 or the universal cords 103 and 113 are formed substantially along the winding shape.

  Note that, as shown in FIG. 13, a guide which is a convex portion is formed between the concave groove 271 and the concave groove 271 by the concave groove 271 formed substantially along the winding shape on the inner surface 3n of the top cover 3. A protrusion 170 is formed. The guide protrusion 170 has a curved surface at each end.

  According to such a configuration, when the top cover 3 is closed with respect to the apparatus main body 2, for example, as shown in FIG. 13, the insertion portion 112 of the endoscope 110, the universal cord 113, and the insertion portion of the endoscope 100. First, the contact 102 is brought into contact with the guide protrusion 170, and is then guided and inserted into the groove 271 by a curved surface formed at the end of the guide protrusion 170. At this time, a gap 291 is formed between the concave groove 271 and the insertion portions 102 and 112 and the universal cord 113.

  Therefore, the insertion portions 102 and 112 and the universal cord 113 do not contact the concave groove 271, that is, do not contact the inner surface 3 n of the top cover 3. Since the cord 113 can be reliably washed and disinfected, the same effect as in the present embodiment can be obtained. Although not shown, the same applies when the universal cord 103 of the endoscope 100 contacts the inner surface 3n of the top cover 3.

  Therefore, in this case, the concave groove 271 and the guide protrusion 170 constitute a gap forming member provided between the inner surface 3n of the top cover 3 and the endoscope 100 or the endoscope 110 in the present invention.

(Fourth embodiment)
FIG. 14 is a partially enlarged cross-sectional view showing a contact state of the holding net with respect to the top cover when the top cover of the endoscope cleaning / disinfecting apparatus showing the present embodiment is closed to the apparatus main body.

  In this embodiment, the inner surface 3n of the top cover 3 and the inner surface 3n of the top cover 3 can be formed in the inner surface 3n of the top cover 3 without forming a convex portion or a groove in the inner surface 3n of the top cover 3, as compared with the first to third embodiments. The only difference is that contact with the endoscopes 100 and 110 can be prevented. Therefore, only this difference is demonstrated, the same code | symbol is attached | subjected to the structure similar to 1st-3rd embodiment, and the description is abbreviate | omitted.

  As shown in FIG. 14, the above-described holding net 60 that is an endoscope holding member is higher than the endoscope 110 placed after the endoscope 110 is placed on the holding net 60. A holding lid 60h is placed on the inner surface 3n side of the cover 3, that is, the outer surface of the endoscope 110 on the housing opening 2s side.

  According to this, when the top cover 3 is closed with respect to the apparatus main body 2, the inner surface 3n of the top cover 3 is attached to the holding lid 60h placed on the outer surface of the endoscope 110 on the side of the accommodation port 2s. Contact. That is, a gap 391 is formed between the inner surface 3n of the top cover 3, the insertion portion 112 of the endoscope 110, and the contact portion 90 of the universal cord 113 by the holding lid 60h.

  Therefore, the inner surface 3n of the top cover 3 does not come into contact with the insertion portion 112 and the universal cord 113 of the endoscope 110. Therefore, the holding net 60 constitutes a gap forming member provided between the inner surface 3n of the top cover 3 and the endoscope 100 or the endoscope 110 in the present invention.

  As described above, in the present embodiment, even when the convex portion 70 or the like cannot be formed on the inner surface 3n of the top cover 3, the same effects as those in the first to third embodiments described above can be obtained. The above is the same even when the contact portion 90 of the endoscope 100 is in contact with the inner surface 3n of the top cover 3, and each contact portion 90 of the two endoscopes 100 and 110 is the top. The same applies to the case of contacting the inner surface 3n of the cover 3.

  15 is a block diagram schematically showing a configuration of an electric circuit when the endoscope and the treatment instrument are ultrasonically cleaned in the endoscope cleaning / disinfecting apparatus of FIG. 1, and FIG. 16 is an internal view of FIG. FIG. 17 is a view showing an ultrasonic cleaning mode selection switch provided on the main operation panel of the mirror cleaning / disinfecting apparatus, FIG. 17 is a view showing a modification of the ultrasonic cleaning mode selection switch of FIG. 16, and FIG. FIG. 19 is a plan view showing the ultrasonic vibration plate and the ultrasonic vibrator. FIG. 19 is a side view of the ultrasonic vibration plate and the ultrasonic vibrator of FIG. 18 when two ultrasonic vibrators having different resonance frequencies are provided. FIG.

  By the way, a known ultrasonic transducer is provided on the back surface of the bottom surface 50t of the tank body 50 of the cleaning / disinfecting tank 4 of the endoscope cleaning / disinfecting apparatus 1 shown in FIG. The endoscope can be ultrasonically cleaned. In addition, when performing ultrasonic cleaning of an endoscope, it is general that the output and the oscillation frequency of the ultrasonic vibrator be set to, for example, about 100 W / 36 kHz in consideration of the durability of the endoscope. .

  In general, the treatment instrument inserted through the above-described treatment instrument insertion conduits of the endoscopes 100 and 110 is separated from the endoscope cleaning and disinfecting apparatus before being sterilized by a known autoclave process or the like. Washed with an ultrasonic washer for the treatment tool. In addition, when performing ultrasonic cleaning of the treatment instrument, the treatment instrument is required to have higher cleaning performance than the endoscope.

  Therefore, when performing ultrasonic cleaning of the treatment tool, taking advantage of the fact that the treatment tool is more resistant to ultrasonic waves than an endoscope, the output of the ultrasonic vibrator is set to 100 W or more, for example, 200 W, and washing unevenness is performed. In order to eliminate this, it is common to use a plurality of oscillation frequencies of 38 kHz to 42.5 kHz.

  For this reason, if the endoscope is ultrasonically cleaned with an ultrasonic washer for a treatment instrument, the durability of the endoscope may be deteriorated. Since ultrasonic cleaning may cause poor cleaning, the user must purchase an endoscope cleaning / disinfecting device that cleans and disinfects the endoscope and an ultrasonic cleaning machine that cleans the treatment tool separately. There was a problem that had to be done.

  In view of such a problem, the endoscope cleaning / disinfecting apparatus 1 according to the first to fourth embodiments described above has a configuration capable of reliably performing ultrasonic cleaning on both the endoscope and the treatment tool. Have.

  Specifically, for example, the main operation panel 25 is provided with an ultrasonic cleaning mode selection switch 120 that constitutes an operation unit for selecting whether an object to be cleaned by ultrasonic cleaning is an endoscope or a treatment tool.

  As shown in FIG. 16, the ultrasonic cleaning mode selection switch 120 may be constituted by a push button switch 120p or may be constituted by a slider switch 120s.

  When the user selects whether the object to be cleaned is an endoscope or a treatment tool by the ultrasonic cleaning mode selection switch 120, the CPU 121 in the apparatus main body 2 shown in FIG. A power supply voltage adjustment signal, an oscillation frequency adjustment signal, and a drive vibrator control signal, which are signals for switching to an ultrasonic output and an oscillation frequency suitable for the above, are output.

  Each component in the block diagram shown in FIG. 15 below is disposed in the apparatus main body 2.

  After that, the voltage phase control unit 130a of the ultrasonic oscillation circuit 130 switches the resistance value for controlling the phase using an electronic switch. As a result, the phase of the input AC voltage from the AC power supply 160 is controlled, and the DC voltage value output from the rectifying / smoothing unit 130b of the ultrasonic oscillation circuit 130 is adjusted.

  The adjusted DC voltage is switched by the drive circuit 130 c and the switching circuit 130 d of the ultrasonic oscillation circuit 130. The switching output on the primary side becomes the output on the secondary side at a ratio of the square of the winding ratio between the primary side and the secondary side by the output transformer 130e of the ultrasonic oscillation circuit 130. For the output on the secondary side, the matching circuit 130f of the ultrasonic oscillation circuit 130 cancels the inherent device capacity of the ultrasonic transducer 181 described later, thereby improving the efficiency.

  As a result, the ultrasonic vibrator 181 located on the back side of the bottom surface 50t of the tank body 50 of the cleaning / disinfecting tank 4 is driven, and the ultrasonic vibration plate 180 fixed to the bottom surface 50t of the tank body 50 vibrates. The object to be cleaned immersed in the cleaning liquid in the cleaning / disinfecting tank 4 is ultrasonically cleaned.

  For the first activation of the switching frequency, initial oscillation is performed in the reference frequency oscillation circuit 130g of the ultrasonic oscillation circuit 130, and after the ultrasonic transducer 181 oscillates, the current and voltage detection circuit 130h of the ultrasonic oscillation circuit 130 is applied. Output current and voltage.

  Then, the phase detection / comparator 130i of the ultrasonic oscillation circuit 130 and the voltage-controlled oscillation circuit 130j to which the oscillation frequency adjustment signal is input automatically track the oscillation frequency of the ultrasonic transducer 181.

  In addition to the method of adjusting the output using the power supply voltage adjustment signal, there is a method of adjusting the output using the drive vibrator control signal.

  As shown in FIG. 18, when eight ultrasonic transducers 181 are provided, for example, when 100 W is output by eight transducers, the ultrasonic waves of the odd number shown in FIG. By opening the vibrator 181, the output is halved to 50 W.

  In addition, as the number of ultrasonic transducers 181 increases, cleaning unevenness in ultrasonic cleaning decreases. Here, as described above, the treatment tool is required to have a higher washing power than the endoscope, so that, for example, eight ultrasonic transducers 181 are configured by two each, and a total of 16 are provided, When the 16 ultrasonic transducers 181 are opened, the output is doubled from the case of 8 and 200 W is output. The 200 W output is used for cleaning the treatment tool. Further, the case where 8 of the 16 ultrasonic transducers 181 are opened and 100 W is output is used for endoscope cleaning.

  Therefore, the electronic transducer or the mechanical switch is used to switch whether the eight ultrasonic transducers 181 or the sixteen ultrasonic transducers 181 are opened according to the drive transducer control signal described above. Then, output control of each ultrasonic transducer 181 is performed.

  The switching of the oscillation frequency is performed by switching the resistance value for adjusting the oscillation frequency of the voltage controlled oscillation circuit 130j with an electronic switch using the above-described oscillation frequency adjustment signal, thereby enabling the switching operation at a different oscillation frequency. It becomes possible.

  Also, if the oscillation frequency of the ultrasonic transducer 181 deviates from the resonance frequency of the ultrasonic transducer 181, the vibration efficiency becomes worse than the phase deviation. Therefore, ultrasonic vibrations having different resonance frequencies as shown in FIG. A total of 16 multi-type ultrasonic transducers 181 in which two or more children 181a and 181b are connected may be used.

  20 is a block diagram schematically illustrating an example in which the ultrasonic oscillation circuit of FIG. 15 is configured by an oscillation circuit and an amplification circuit. FIG. 21 is a diagram in which a relay circuit is provided in the ultrasonic oscillation circuit of FIG. It is a block diagram which shows roughly the structure which oscillates each ultrasonic transducer | vibrator separately.

  As shown in FIG. 20, the configuration of the ultrasonic oscillation circuit 130 may not be the one using the switching circuit 130 d shown in FIG. 15, but may be a configuration of a voltage control oscillation circuit 130 j + an amplification circuit 141. In this case, the oscillation frequency is switched by the voltage controlled oscillation circuit 130j, and the output is switched by the amplifier circuit 141.

  When the ultrasonic transducer 181 is composed of a plurality of ultrasonic transducers 181, in addition to the configuration of FIG. 20, a relay circuit 142 is provided in the ultrasonic oscillation circuit 130 as shown in FIG. When the relay circuit 142 is turned off, one ultrasonic transducer 181k may be oscillated, and when the relay circuit 142 is turned on, the two ultrasonic transducers 181k and 181m may both be oscillated.

  According to the configuration of the ultrasonic oscillation circuit 130 described above, after the ultrasonic cleaning mode selection switch 120 is switched by the user, the internal voltage is detected by the power supply voltage adjustment signal or the drive vibrator control signal output from the CPU 121. Since the ultrasonic output can be switched between when the mirror is ultrasonically cleaned and when the treatment tool is ultrasonically cleaned, different ultrasonic characteristics are output by one endoscope cleaning / disinfecting apparatus 1. In addition, the endoscope and the treatment instrument can be reliably ultrasonically washed while ensuring durability against ultrasonic waves. Also, it is not necessary to install two units, an endoscope cleaning / disinfecting device and an ultrasonic cleaning device for a treatment tool, in the treatment room.

  In addition, the function of the endoscope cleaning / disinfecting apparatus 1 can be used as it is for cleaning the treatment instrument. For example, a water filter that removes germs from tap water can be used for tap water supply for washing, and high-speed drainage can be automatically performed by a drain pump for drainage, and an automatic supply of detergent as necessary. In addition, it is possible to achieve a higher cleaning effect on the treatment instrument and a reduction in process time than using an ultrasonic washer for the treatment instrument by being able to use a combination of ultrasonic washing with a flowing liquid washing etc. Can do.

  Furthermore, by providing a protection means serving as an identification function for discriminating between the endoscope and the treatment tool, it is possible to prevent damage to the endoscope and poor cleaning of the treatment tool due to an operation error. FIG. 22 is a block diagram showing an example in which a protection unit for discriminating between an endoscope and a treatment tool is provided in the apparatus main body of FIG.

  As an identification function for discriminating between an endoscope and a treatment tool, for example, a method of discriminating an object to be cleaned with a unique parameter such as an ID or a barcode, or, normally, each pipe line of the endoscopes 100 and 110 has a pipe Each of the ports on the endoscope cleaning / disinfecting apparatus 1 side is cleaned by connecting the branch tubes 150, 151 connected to the ports 33 to the pipe connection ports 98, 99, 198, 199 of the road. There is a method for determining the connection of the endoscope by providing a scope attachment / detachment recognition unit such as a pressure sensor in 33a and 33b.

  Specifically, first, in the method for discriminating the item to be cleaned based on the ID, as shown in FIG. 22, a protection means 145 is provided in the apparatus body 2, and the ID identification unit 145a of the protection means 145 is provided with By automatically recognizing IDs respectively provided for the endoscope and the treatment tool that are objects, the CPU 121 performs switching to output an ultrasonic wave adapted to the article to be cleaned.

  Thus, by automatically recognizing the object to be cleaned by the ID identification unit 145a, when the object to be cleaned is an endoscope, ultrasonic waves for the treatment tool are output, and the durability of the endoscope Can be prevented from deteriorating. Conversely, when the object to be cleaned is a treatment tool, it is possible to prevent the ultrasonic wave for the endoscope from being output and the treatment tool from being insufficiently cleaned.

  Next, in the method of determining the object to be cleaned by determining the connection of the endoscope, the scope attachment / detachment recognition unit 145b of the protection unit 145 supplies air or water to the pipelines of the endoscopes 100 and 110. , The pressure of the air supply or water supply is measured to determine whether the pipe connection ports 98, 99, 198, 199 are connected to the ports 33a, 33b described above via the branch tubes 150, 151. To make a decision.

  Specifically, if the pressure is detected, the scope attachment / detachment recognition unit 145b determines that the object to be cleaned is an endoscope, and if the pressure is not detected, the treatment instrument is cleaned by connecting a cleaning tube. Therefore, it is determined that the object to be cleaned is a treatment tool. As a result, the CPU 121 performs switching to output an ultrasonic wave adapted to the article to be cleaned. Also by this, the same effect as in the case of ID can be obtained.

  Note that the ID recognition by the ID identification unit 145a and the determination of whether or not the endoscope is connected by the scope attachment / detachment recognition unit 145b may be performed simultaneously. Moreover, if this is used, it is not necessary for the user to select the ultrasonic cleaning mode selection switch 120.
