Detailed Description

In order to more clearly illustrate the technical solutions of the embodiments of the present specification, the drawings that are required to be used in the description of the embodiments will be briefly described below. It is apparent that the drawings in the following description are only some examples or embodiments of the present specification, and it is possible for those of ordinary skill in the art to apply the present specification to other similar situations according to the drawings without inventive effort. Unless otherwise apparent from the context of the language or otherwise specified, like reference numerals in the figures refer to like structures or operations.

As used in this specification and the claims, the terms "a," "an," "the," and/or "the" are not specific to a singular, but may include a plurality, unless the context clearly dictates otherwise. In general, the terms "comprises" and "comprising" merely indicate that the steps and elements are explicitly identified, and they do not constitute an exclusive list, as other steps or elements may be included in a method or apparatus.

The endoscope cleaning mainly comprises the following steps: pre-bed cleaning, leak detection, water washing, enzyme liquid cleaning, water washing, disinfectant soaking, water washing, drying and the like. The endoscope washer may perform some or all of the washing operations other than pre-bed washing. In some embodiments, the endoscope cleaner is used in conjunction with manual operation to perform a partial cleaning operation or a change over of a cleaning operation, e.g., the endoscope cleaner is provided with dedicated operation tanks for each cleaning step, including a primary tank, an enzyme tank, a secondary tank, a disinfection tank, a final tank, etc., and at least manual operation is required to perform a change over of the endoscope during each cleaning step switching stage. In some embodiments, the endoscope cleaner directly fills each cleaning material (such as water, zymogen liquid, etc.) into the operation tank, so that the preparation of the cleaning solution (such as enzyme washing liquid) and the cleaning operation are synchronously performed, and the problem of uneven solution preparation is difficult to avoid, which results in incomplete cleaning and disinfection. In some embodiments, the endoscope cleaner is difficult to clean internally by an operator, and the risk of cross-contamination is high, especially in the case of using the endoscope cleaner to clean different kinds of endoscopes (e.g., enteroscopes, hysteroscopes, choledochoscopes, etc.). In some embodiments, the endoscope washer uses the same wash tank to wash different kinds of endoscopes, increasing the risk of cross-contamination.

Some embodiments of the present description provide an endoscope cleaning apparatus (or referred to as an endoscope cleaner). The endoscope cleaning equipment can realize one or more functions of full-automatic cleaning, automatic liquid distribution, pipeline self-cleaning, cleaning tank replacement and the like. The endoscope cleaning equipment can achieve one or more beneficial effects of reducing the manual participation degree of cleaning operation, improving the using convenience, improving the utilization rate of cleaning materials, reducing the risk of cross infection and the like.

The endoscope cleaning apparatus according to the embodiments of the present specification will be described in detail with reference to fig. 1 to 24.

In order to further enhance the atomization effect, the second spray can 327 may be provided with a porous material, similar to the first spray can 322, and details thereof are not described herein.

In some embodiments, a second mist delivery portion 328 is provided between the second spray mixing tank 327 and the endoscope main delivery portion 333, for delivering the alcohol mist supplied from the second spray mixing tank 327 to the endoscope main delivery portion 333 and then to the tube to be cleaned of the endoscope 90 via the endoscope main delivery portion 333. In some embodiments, the second mist delivery part 328 includes a second mist delivery pipe 328a, and a one-way valve 328c and an air valve 328b provided in the second mist delivery pipe 328a in the mist delivery direction. Illustratively, as shown in fig. 6, the inlet end of the second mist transporting pipe 328a is connected to the second mist mixing tank, the outlet end of the second mist transporting pipe 328a is connected to the main transporting pipe of the endoscope 90 of the main transporting portion 333 of the endoscope, the outlet ends of the sub transporting pipes 333a,333b,333c of the main transporting portion 333 of the endoscope are respectively connected to the corresponding cleaning joints in the cleaning tank 20, and the cleaning joints are respectively connected to the corresponding interfaces of the respective pipes to be cleaned of the endoscope 90, so that the alcohol mist is respectively supplied into the respective pipes to be cleaned of the endoscope 90 through the sub transporting pipes 333a,333b,333c for disinfection and drying.

In some embodiments, processor 60 may control the second spraying unit to disinfect and dry the interior of endoscope 90. Further, the processor 60 may control the opening of the liquid inlet valve 329b, the air valve 326b and the air valve 328b, and control the driving pump 319b and the second air pump 325 to cooperate, so that the alcohol accumulated in the second spray mixing tank 327 forms alcohol mist under the pressure of the air supplied from the second air pump 325, and the alcohol mist with pressure is supplied into the tube to be cleaned of the endoscope 90 through the second mist delivery tube 328a and the corresponding tube of the endoscope main delivery part 333, respectively.

The air tightness detection mechanism may be used to perform air tightness detection on endoscope 90 before the cleaning procedure is initiated and/or during the cleaning procedure. In some embodiments, the air tightness detection mechanism includes a gas tank 331, a first pressure-regulating delivery portion 330, and a second pressure-regulating delivery portion 332. The gas tank 331 is configured to store pressure gas supplied by the gas source assembly, the first pressure-regulating conveying portion 330 regulates the pressure of the pressure gas supplied by the gas source assembly, and maintains the gas pressure in the gas tank 331 relatively stable, and the second pressure-regulating conveying portion 332 conveys the pressure gas stored in the gas tank 331 to the leak detection interface of the endoscope 90 after regulating the pressure secondarily, so as to detect the air tightness of the pipeline to be detected. Specifically, compared with the gas source assembly used for directly supplying gas to the endoscope 90 and detecting the air tightness, the air tightness detection mechanism can improve the stability of supplying gas into the endoscope by arranging the gas tank and components related to pressure regulation and voltage stabilization, thereby improving the sensitivity and reliability of air tightness detection; on the other hand, the air source component does not need to continuously supply air, and after the pressure of the air tank is stable, the air source component can stop supplying air to the air tank, so that the energy consumption and the use cost can be reduced.

In some embodiments, the air tightness detection mechanism and the second spraying unit share an air source component, i.e. the second air pump 325 is used to provide the air tightness detection mechanism and the second spraying unit with pressurized air. Illustratively, as shown in fig. 6, the second air pump 325 communicates with the air tank 331 through the first pressure-regulating delivery section 330, and supplies pressure gas to the air tank 331; the second gas delivery pipe 326a of the second spraying unit communicates with the second gas pump 325 through the first pressure-regulating delivery part 330, and the second gas pump 325 supplies the pressure gas to the second spraying unit. Because the air tightness detection mechanism is provided with the air tank 331 for storing air and the first pressure regulating conveying part 330 for regulating and maintaining the pressure of the air tank 331, after the pressure of the air tank 331 is stable, the second air pump 325 does not need to continuously provide pressure air for the air tank 331, and can be used as an air source of the second spraying unit, so that the equipment structure is optimized, and the manufacturing and using costs are saved. In other embodiments, the gas source assembly further comprises a third gas pump that is used solely to provide pressurized gas to the gas tightness detection mechanism.

In some embodiments, the first pressure regulating delivery section 330 includes a regulated pressure conduit 330b and a regulated pressure conduit 330a disposed in parallel between the gas source assembly and the gas tank 331, and a pressure switch 330d disposed on the regulated pressure conduit 330b and a primary pressure regulating valve 330c disposed on the regulated pressure conduit 330 a. Illustratively, as shown in fig. 6, the pressure stabilizing pipe 330b and the pressure regulating pipe 330a are disposed in parallel between the second air pump 325 and the air tank 331, the primary pressure regulating valve 330c disposed on the pressure regulating pipe 330a primarily regulates the pressure of the pressure air supplied from the second air pump 325, and the pressure switch 330d disposed on the pressure stabilizing pipe 330b maintains the stored air in the air tank 331 within a relatively stable pressure range. In some embodiments, a gas filter 330e is further disposed on the pressure regulating pipeline 330a, for filtering the gas provided by the second air pump 325, so as to meet the requirement of cleaning the endoscope 90.

In some embodiments, the operation of the second air pump 325 is controlled by automatic feedback adjustment of the pressure switch 330 d. Illustratively, the pressure switch 330d has a pressure range of the switching action, and when the pressure in the pressure regulating conduit 330a is lower than the lowest pressure value, the pressure switch 330d automatically opens to cause the second air pump 325 to supply air to the air tank 331; when the pressure of the pressure regulating pipe 330a is higher than the highest pressure value, the pressure switch 330d is automatically turned off to stop the second air pump 325 from supplying air to the air tank 331.

In some embodiments, the second pressure regulating delivery portion 332 includes a leak-finding conduit 332a and a secondary pressure regulating valve 332b disposed on the leak-finding conduit 332 a. As shown in fig. 6, for example, the inlet end of the leak detection pipe 332a is connected to the gas tank 331, the secondary pressure regulating valve 332b on the leak detection pipe 332a performs secondary accurate pressure regulation on the gas delivered by the gas tank 331, the outlet end of the leak detection pipe 332a is connected to the leak detection joint 206, the leak detection joint 206 in the cleaning tank 20 is connected to the leak detection port (e.g. through a hose connection) of the endoscope 90, and the gas subjected to secondary pressure regulation is delivered to the pipeline to be detected of the endoscope 90 through the leak detection port for air tightness detection. In some embodiments, second pressure regulating delivery portion 332 further comprises a pressure sensor 332c for measuring a leak-finding pressure of endoscope 90. As shown in fig. 6, a pressure sensor 332c is provided between the leak detection joint 206 and the secondary pressure regulating valve 332b. In some embodiments, the second pressure regulating delivery portion 332 further includes a gas valve 332d disposed between the gas tank 331 and the secondary pressure regulating valve 332b.

In some embodiments, processor 60 may control the air tightness detection mechanism to perform air tightness detection on endoscope 90. Illustratively, after the leak detection connector 206 of the second pressure-regulating delivery unit 332 is connected to the leak detection connector of the endoscope 90, the processor 60 may control the air valve 332d to open, and the air tank 331 supplies air to the to-be-detected pipeline of the endoscope 90 through the second pressure-regulating delivery unit 332; the processor 60 may obtain the leak detection pressure measured by the pressure sensor 332c, and when the leak detection pressure reaches the predetermined pressure range, the processor 60 may control the gas valve 332d to close so that the gas is enclosed in the pipeline to be detected of the endoscope 90, and the pressure sensor 332c continuously measures the leak detection pressure of the pipeline to be detected. If there is an air tightness problem in the pipeline to be detected of the endoscope 90, so that the leak detection pressure measured by the pressure sensor 332c is lower than the preset value, the processor 60 controls the pipeline system 30 to stop working, and issues an alarm indicating that the endoscope 90 has the air tightness problem.

In some embodiments, each infusion line (e.g., first branch supply line 301a, main supply line 308a, main drain line 310a, etc.) of tubing 30 may be a textured silicone hose. Specifically, under the condition of circulating high-pressure liquid, compared with a plastic pipe, a rubber pipe and a metal hard pipe, the high-pressure-resistant and high-flexibility characteristics of the reticulate silica gel hose can reduce vibration of the pipeline and noise. In some embodiments, each of the inlet valves of piping system 30 (e.g., inlet valve 302c, inlet valve 308e, inlet valve 311b, etc.) may be a bi-stable solenoid valve. Specifically, the bistable electromagnetic valve has the characteristics of high precision, small volume, quick response, light weight and the like, can realize complex fluid movement, and has the function of preventing water hammer so as to reduce equipment vibration and noise. In some embodiments, the water pump of the pipeline system 30 may be a high-power high-flow self-priming water pump, so as to ensure the flow rate of the liquid in the cleaning process and improve the cleaning effect of the endoscope.

Fig. 9 and 10 are schematic structural views of an endoscope cleaning apparatus according to some embodiments of the present disclosure, with the upper cover 50 in various open and closed states. In some embodiments, the endoscope cleaning apparatus is also provided with an upper cover 50. Specifically, the upper cover 50 may be used to open and close the opening at the top of the washing tub 20. As shown in fig. 9 and 10, for example, the upper cover 50 is rotatably coupled to the top of the body 10, and the upper cover bottom surface 50a is covered on the opening of the top of the washing tub 20 by turning the upper cover 50 to close the washing tub 20.

Fig. 11 to 13 are schematic structural views of the upper cover 50 according to some embodiments of the present specification. In some embodiments, the height of the upper cover bottom surface 50a gradually decreases from the middle to the edge. As shown in fig. 12, the bottom surface 50a of the upper cover is an arc surface, the middle of the bottom surface 50a is higher than the edge of the bottom surface 50a, and when the liquid drops accumulated in the middle of the bottom surface 50a gradually increase, the liquid drops flow to the edge of the bottom surface 50a under the action of gravity and drop into the cleaning tank 20 along the inner wall of the cleaning tank 20, so that the liquid accumulation and residue on the bottom surface 50a of the upper cover are avoided.

In some embodiments, the upper cover 20 is made of a hydrophobic material. In some embodiments, the upper cover bottom surface 50a is provided with a hydrophobic coating. In particular, the hydrophobicity of the bottom surface 50a of the upper cover can reduce liquid accumulation and residue, thereby facilitating disinfection and drying of the upper cover. In some embodiments, the hydrophobic coating may be formed of a hydrophobic material coated on the upper cover bottom surface 50 a. In some embodiments, the composition of the hydrophobic material may include isopropyl alcohol and silicone oil.

In some embodiments, at least a portion of the upper cover 50 is made of a transparent material. In particular, partially transparent upper cover 50 allows a user to view the airtight detection and/or cleaning of endoscope 90 within cleaning tank 20 through upper cover 50. Illustratively, in the cleaning procedure, a user may observe the condition of soaking, spraying, and drying of the endoscope 90 through the upper cover 50.

In some embodiments, as shown in fig. 11-13, a spray rinsing device 315 of the fluid circuit system is mounted on the upper cover bottom surface 50 a. Preferably, a shower flushing device 315 may be installed at the middle portion of the bottom surface 50a of the upper cover. After the upper cover 50 is turned over and the cleaning tank 20 is closed, the spray rinsing device 315 may output the liquid supplied from the liquid path system into the cleaning tank 20 in a spray (e.g., spin spray) manner. The installation position of the spray rinsing device 315 is not limited to the upper cover 50, but may be the inner wall of the cleaning tank 20; the number of the shower flushing devices 315 is not limited to one, but may be plural (e.g., 2, 3), and the present embodiment is not limited thereto.

Fig. 14 and 15 are schematic structural views of a spray rinsing device 315 according to some embodiments of the present disclosure. In some embodiments, the spray rinse device 315 may perform a rotary spray. Further, as shown in fig. 14 and 15, the spray rinsing device 315 includes a spray head 3152 and a spray base 3151, which are rotatably coupled. In some embodiments, the liquid spray head 3152 and the liquid spray base 3151 are provided with ceramic bearings and sealing rings to improve the tightness of the spray rinsing device 315 when rotated, and ensure that the rotational connection structure between the liquid spray head 3152 and the liquid spray base 3151 is waterproof and corrosion-resistant. In some embodiments, the liquid jet head 3152 is in a three-prong configuration. Further, as shown in fig. 14 and 15, the liquid ejection head 3152 has three liquid ejection levers 3152', and the three liquid ejection levers 3152' are rotationally symmetrical with respect to the rotation axis of the liquid ejection head 3152. Specifically, the three-prong rotationally symmetrical structure of the liquid jet 3152 can improve the uniformity of the liquid spray. In some embodiments, the number of liquid ejecting bars 3152' provided on the liquid ejecting head 3152 is not limited to 3, but may be 1, 2, or more than 3, and the present embodiment is not limited thereto.

In some embodiments, the spray rinse device 315 may be self-rotating through the setting of the spray direction. Further, as shown in fig. 15, liquid ejecting nozzles 3152c provided on the liquid ejecting lever are each arranged eccentrically and obliquely with respect to the rotation axis of the liquid ejecting head 3152, so that the liquid ejected from the liquid ejecting nozzles 3152c causes the liquid ejecting head 3152 to self-rotate (e.g., the reaction force of the ejected liquid causes the liquid ejecting head 3152 to self-rotate). Specifically, the structure of spray rinsing device 315 (e.g., a three-prong structure, a direction in which liquid spray 3152c is disposed, etc.) may partially convert the liquid pressure into a pushing force that pushes liquid spray 3152 to rotate. Furthermore, the self-rotating liquid spraying head can enable the spraying water column with pressure to continuously and uniformly impact the surfaces of the cleaning tank and the endoscope, particularly impact the dirt outside the endoscope, which is difficult to be carried away in a soaking mode, so that the cleaning effect is improved.

In some embodiments, the direction of liquid spray from the spray rinse device 315 is adjustable. Further, the liquid spraying lever 3152' may include a lever 3152a and a sleeve 3152b coaxially sleeved on the lever 3152a, the lever 3152a is rotatably connected to the sleeve 3152b, and the liquid spraying nozzle 3152c is disposed on the sleeve 3152 b. Spray rinsing device 315 can adjust the spray direction of spray nozzle 3152c by rotating sleeve arm 3152 b. In some embodiments, a plurality of liquid ejection nozzles 3152c are provided on each of the arms 3152b, and the plurality of liquid ejection nozzles 3152c on the same arm 3152b are arranged at intervals along the axial direction of the arm 3152 b. The liquid ejection directions of the liquid ejection nozzles 3152c on the same set of arms 3152b may be the same or different, and the present embodiment is not limited. In some embodiments, adjusting the ejection direction of liquid jet head 3152c by rotating sleeve arm 3152b may adjust the direction and/or speed of liquid jet head 3152 self-rotation. In some embodiments, the greater the angle of ejection direction of liquid jet head 3152c from the vertical, the greater the speed at which liquid jet head 3152 self-rotates.

Fig. 16 and 17 are schematic structural views of an injector 324 according to some embodiments of the present disclosure. In some embodiments, as shown in fig. 11-13, the injector 324 of the air path system is mounted on the upper cover bottom surface 50 a. After the upper cover 50 is turned over and the cleaning tank 20 is closed, the injector 324 may output the alcohol mist supplied from the gas path system into the cleaning tank 20 in a spray manner. In some embodiments, injector 324 may perform rotary jetting. In some embodiments, as shown in fig. 16 and 17, the injector 324 may include a jet head 3242 and a jet base 3241, both rotatably connected. The showerhead 3242 is in a trifurcated configuration. In some embodiments, the showerhead 3242 includes three arms 3242a, the three arms 3242a being rotationally symmetrical with respect to the axis of rotation of the showerhead 3242. Specifically, the tri-fork rotationally symmetrical structure of the showerhead 3242 may improve uniformity of gas injection. In some embodiments, the injector 324 may be self-rotating through the setting of the injection direction. Specifically, the air nozzles 3242b provided on the arm portions 3242a are arranged eccentrically and obliquely with respect to the rotation axis of the air jet head 3242, so that the alcohol mist sprayed from the air nozzles 3242b drives the air jet head 3242 to rotate. Specifically, the structure of the ejector 324 (such as the three-fork structure, the direction in which the liquid spraying nozzle 3152c is arranged, etc.) can partially convert the gas pressure into a pushing force for pushing the jet head 3242 to rotate, and further, the jet head 3242 with self rotation can enable the gas column with pressure to continuously and uniformly impact the cleaning tank and the surface of the endoscope, so that the liquid attached to the outer part of the endoscope can be quickly separated from the endoscope, especially impact the outer part of the endoscope, which is easy to accumulate due to the compact structure, so as to promote the disinfection and drying effects.

In some embodiments, injector 324 may inject gas simultaneously onto lid 50 and rinse tank 20. Further, the arm portion 3242a is provided with a plurality of air nozzles 3242b, and the ejection direction of a part of the air nozzles 3242b among the plurality of air nozzles 3242b is directed toward the upper cover 50, and the ejection direction of a part of the air nozzles 3242b among the plurality of air nozzles 3242b is directed toward the cleaning bath 20. In some embodiments, the upper lid bottom surface 50a is provided with two counter-rotating injectors 324, and the alcohol mist sprayed by the two injectors 324 sweeps the liquid on the upper lid 50 from the middle to the edge of the upper lid 50. Wherein counter rotation means that the rotation directions of the two ejectors 324 are opposite. In some embodiments, the gas nozzles 3242b of the two injectors 324 are oriented in different gas injection directions, such that the direction of self-rotation of the two injectors 324 is reversed. Preferably, the two sprayers 324 are centered symmetrically with respect to the spray rinsing device 315 mounted in the middle of the upper cover 50. The arrangement of two sprayers 324 to the rotary spray gas can dry and sterilize the cleaning tank 20, the endoscope and the bottom surface 50a of the upper cover at the same time, thereby avoiding the dead cleaning angle of the bottom surface 50a of the upper cover, and further causing liquid accumulation and residue so as to reduce the risk of cross infection.

In some embodiments, body 10 is removably coupled to washing tank 20. Specifically, the machine body 10 may be provided with a cleaning tank installation position. In some embodiments, a wash tank mounting station may be equipped with one wash tank 20, the wash tank 20 may be used to house multiple types of endoscopes 90, and the wash tank may be removed from the wash tank mounting station for deep cleaning to reduce the risk of cross-contamination. In some embodiments, the wash tank mounting location may be selectively equipped with different wash tanks 20, each wash tank 20 may correspondingly house a particular type of endoscope 90, by defining wash tank 20 to house, wash a particular type of endoscope 90, the risk of cross-contamination between the various types of endoscopes can be reduced. In some embodiments, a water guide groove is provided on the cleaning tank installation site, and the water guide groove is used for collecting the liquid leaked from the cleaning tank 20. Illustratively, when the washing tub 20 is assembled with the washing tub installation site, the water guide groove is located at the periphery of the top opening of the washing tub 20. Specifically, the liquid leaking from the gap between the cleaning tank 20 and the upper cover 50 (such as liquid splashed by the liquid column impacting the endoscope, liquid effusion oozed from the edge of the upper cover, etc.) can be collected in the water guide tank, so that the liquid can be prevented from flowing into the machine body to cause equipment failure.

Fig. 21 to 23 are schematic structural views of the cleaning tank 20 according to some embodiments of the present specification. In some embodiments, the cleaning tank 20 is provided with a liquid inlet 204, and the liquid inlet 204 is in communication with the piping system 30. The tubing 30 delivers liquid to the wash tank 20 such that the tubing that soaks the endoscope 90 communicates with the liquid inlet 204 of the wash tank 20. In some embodiments, liquid inlet 204 introduces liquid tangentially to wash tank 20, enabling the liquid to form a vortex within wash tank 20. Illustratively, as shown in fig. 23, the cleaning tank 20 has a generally oval inner contour in plan view, and the liquid inlet 204 is provided on the cylindrical side wall of the cleaning tank 20. As shown in fig. 21 and 23, the liquid inlet 204 has a liquid inlet direction substantially coincident with a tangential direction of the liquid inlet 204 on the cylindrical side wall, so that the liquid entering the cleaning tank 20 through the liquid inlet 204 flows against the wall and forms a vortex in the cleaning tank 20. Specifically, the liquid for soaking the endoscope forms vortex in the cleaning tank 20, so that the liquid can uniformly wash all parts outside the endoscope, especially the parts of the endoscope which are difficult to clean due to the complex and compact structure, and compared with the static soaking of the liquid, the flowing soaking of the liquid can improve the cleaning effect; on the other hand, the vortex can be formed to enable the cleaning liquid to be quickly mixed, so that obvious concentration difference between the effective concentration of the cleaning liquid and the position far away from the endoscope is avoided.

In some embodiments, the cleaning tank 20 is provided with a liquid outlet 205, and the liquid outlet 205 communicates with the piping system 30. The pipe system 30 receives the liquid output from the cleaning tank 20 and communicates with the liquid outlet 205 of the cleaning tank 20. In some embodiments, the liquid outlet 205 is disposed at the bottom of the cleaning tank 20. As shown in fig. 21, the liquid outlet 205 is provided at the lowest level of the bottom of the cleaning tank 20 to facilitate liquid evacuation and reduce liquid residue. In some embodiments, the liquid outlet 205 is located in a non-edge region of the bottom of the cleaning tank 20. As used herein, a non-edge region refers to a region at least a predetermined distance (e.g., 3cm or 5 cm) from the bottom edge of the cleaning tank 20. When the cleaning tank 20 simultaneously introduces liquid through the liquid inlet 204 and discharges liquid through the liquid outlet 205, providing the liquid outlet 205 in a non-edge region can avoid the discharge of liquid from affecting the liquid tangentially introduced into the cleaning tank 20 to form a vortex.

Fig. 24 is a schematic view of a scenario in which wash tank 20 accommodates endoscope 90, according to some embodiments of the present description. In some embodiments, as shown in fig. 24, a groove 201 for placing the endoscope 90 is provided inside the cleaning tank 20, and the groove 201 may be in a form-fitting engagement with the endoscope 90. As used herein, contoured fit refers to machining grooves 201 having a similar or identical profile shape to follow the outer contour of endoscope 90. Specifically, the groove 201 is located at the bottom of the washing tub 20, and the groove 201 includes a main body portion for mainly accommodating the connection portion and the operation portion of the endoscope 90, and an annular portion for mainly accommodating the flexible tube body (e.g., insertion portion) of the endoscope 90. The profiling arrangement of the grooves 201 can prevent the tube body of the endoscope 90 from winding and bending, and can facilitate the guiding of the cleaning liquid in the direction indicated by the arrow in fig. 23 to form vortex in the grooves 201, thereby enhancing the cleaning force of soaking and cleaning.

In some embodiments, the downward recessed groove 201 forms a plurality of bosses 203 at the bottom of the cleaning tank 20, at least a portion of the top of the bosses 203 being higher than the level of the cleaning liquid in the cleaning tank 20. Specifically, due to the profiling arrangement of the grooves 201, the amount of the liquid to be fed into the endoscope 90 is controlled to a level sufficient to submerge all the bosses 203, so that the amount of the liquid to be used for cleaning can be greatly reduced while ensuring the cleaning effect, and the use cost can be reduced.

In some embodiments, at least a portion of the sidewalls of the recess 201 have a gradual slope. Specifically, the slope of the side wall of the groove 201 makes the side wall smooth and excessive in the horizontal direction and the vertical direction, which is beneficial to reducing the flow resistance of the liquid, and meanwhile, has a certain guiding effect on the flow direction of the liquid, so that the vortex is convenient to form.

In some embodiments, a plurality of protrusions 202 are provided on the bottom of wash tank 20, protrusions 202 being configured to support endoscope 90. As shown in fig. 22, each of the protrusions 202 protrudes from the bottom of the groove 201, and a plurality of protrusions 202 are arranged at intervals at the bottom of the groove 201. Specifically, the protrusion 202 supports the endoscope 90, so that on one hand, a gap is formed between the endoscope 90 and the bottom of the groove 201 to allow flowing liquid to wash the supported surface of the endoscope 90 below, and on the other hand, the protrusion 202 can reduce the contact area between the endoscope 90 and the bottom of the groove 201, reduce the cleaning dead angle, and improve the cleaning efficiency.

In some embodiments, the downward concave groove 201 forms a plurality of bosses 203 at the bottom of the cleaning tank 20, and the bosses 203 are provided with a leak detection joint 206 for communicating with a leak detection port of the endoscope 90, and a cleaning joint 207,208,209 for communicating with a pipe to be cleaned of the endoscope 90. The tubing system 30 supplies liquid and/or gas to the interior of the endoscope 90 via the leak detection fitting 206 and the purge fitting 207,208,209 described above. Specifically, the leak detection joint 206, the cleaning joint 207,208,209 and the corresponding interfaces of the endoscope 90 are connected through flexible pipelines, and the leak detection joint 206 and the cleaning joint 207,208,209 are arranged on the boss 203, so that the length of the connecting pipeline can be shortened, and meanwhile, interference obstruction of the connecting pipeline to the flow of liquid in the cleaning tank 20 can be reduced, and the cleaning efficiency is improved.

In some embodiments, the inner wall of the wash tank 20 is provided with a hydrophobic coating. Specifically, the hydrophobic coating can reduce liquid residue after draining the liquid in the cleaning tank 20, reduce the workload of drying operation, and simultaneously reduce the flow resistance of the cleaning liquid, thereby further improving the cleaning efficiency. In some embodiments, the hydrophobic coating may be formed by coating a hydrophobic material on the inner wall surface of the cleaning tank. In some embodiments, the composition of the hydrophobic material may include isopropyl alcohol and silicone oil.
