Description

Technical Field

[0001] The invention relates to the field of pre-cleaning of digestive endoscopes, and in particular to a pre-cleaning device for a digestive endoscope and a use method thereof. Background Art

[0002] After extubation during endoscopic examination, before detaching from the light source and video processor, immediately wipe off visible dirt on the outer surface of the digestive endoscope with gauze with detergent, then put the insertion part into clean water and repeatedly supply air and water for at least 10 minutes. At the same time, a dedicated nurse should clean the surface of the endoscope several times with sterile gauze, turn off the power and host, remove the endoscope and send it to the cleaning and disinfection room for water washing → enzyme washing → secondary cleaning → disinfection → final rinse.

[0003] The prior art discloses some patent documents about the pre-cleaning of digestive endoscopes. A Chinese patent with application number 202220306357.2 discloses a patent for a pre-cleaning device for digestive endoscopes, including a pedal-operated trash can, a funnel, a storage tank containing enzymes, and a suction device. The pedal-operated trash can includes a barrel body and a barrel cover rotatably connected to the barrel body. A drawstring garbage bag is sleeved in the barrel body. A through hole is provided in the barrel cover. The lower end of the funnel passes through the through hole and is inserted into the drawstring garbage bag. An annular convex edge is provided on the outer wall of the upper end of the funnel for abutting against the upper end surface of the barrel cover. The funnel is detachably connected to the barrel cover. The funnel is used for allowing the lens of the digestive endoscope to pass through so that the lens of the digestive endoscope can be inserted into the drawstring garbage bag. The suction device is connected to the barrel cover and is used to pump the enzyme in the storage tank into the drawstring garbage bag. A controller and a control button are fixed on the outer wall of the barrel body.

[0004] At present, when pre-cleaning the insertion part of a digestive endoscope after use, most nurses hold the handpiece of the digestive endoscope in one hand and use the other hand to hold a gauze with a cleaning agent and wipe the surface of the insertion part from top to bottom, so as to wipe off the dirt visible to the naked eye on the outer surface of the digestive endoscope. This manual cleaning method is prone to uneven force on the surface of the digestive endoscope due to negligence of the staff during the wiping process, resulting in incomplete cleaning.

When the wiping cotton is out of contact with the insertion part of the digestive endoscope, under the guidance of the guiding mechanism, the mounting frame is driven to slide along the top of the support plate, thereby guiding the wiping cotton after wiping the dirt to the cleaning station and stopping. At this time, the controller controls the cleaning mechanism to clean the surface of the wiping cotton, which is beneficial to maintain the clean state of the wiping cotton and avoid the phenomenon that the dirt after wiping is adsorbed on the surface of the wiping cotton. The whole process is more automatic and intelligent, and automatically realizes the soaking of the wiping cotton and the automatic cleaning of the wiping cotton after wiping is completed.

[0022] The swab is then moved to the side of the cover plate, and the swab is then moved to the side of the cover plate, and the swab moves along the inner wall of the cover plate, thereby moving the swab to the side of the cover plate and moving the swab to the side of the cover plate.

[0023] 3. When the support plate moves to the bottom and stops, the wipe cotton moves to the cleaning station after wiping, and water is sprayed on the wipe cotton through the spray mechanism, so that the dirt on the surface of the wipe cotton can be taken away with the help of water flow. The third electric cylinder is started by the controller to move the rotating plate to the middle of the two wipe cottons, and the four fourth electric cylinders and the second motor are started by the controller. The piston rods of the four fourth electric cylinders push the second mounting plate connected to the rollers to move, and the moving rollers will be squeezed and contacted with the surface of the wipe cotton. The output shaft of the second motor drives the rotating plate to rotate, thereby driving multiple rollers to rotate. When the rotating rollers pass through the surface of the wipe cotton, they will squeeze the surface of the wipe cotton, so that the dirt in the wipe cotton can be squeezed and washed away in the process of spraying water by the spray mechanism.

DETAILED DESCRIPTION

[0042] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0043] like Figures 2 to 17 The pre-cleaning device for digestive endoscope shown in the figure comprises a mounting seat 1, a cleaning box 2 is fixedly connected to the top of the mounting seat 1, a box cover 3 is fixedly connected to the top of the cleaning box 2, and a sewage pipe 4 is fixedly connected to the bottom of the cleaning box 2. It is characterized in that an insertion hole 5 is opened through the top of the box cover 3, and support plates 6 are symmetrically and vertically slidably connected to the inner wall of the cleaning box 2. A driving mechanism is commonly provided between the two support plates 6, and the driving mechanism is used to drive the two support plates 6 to move vertically. The tops of the two support plates 6 are both slidably connected to A mounting frame 7, the inner walls of the two mounting frames 7 are fixedly connected with a first electric cylinder 8, the piston rod ends of the two first electric cylinders 8 are fixedly connected with a clamping shell 9, the shell openings of the two clamping shells 9 are provided with an arc-shaped opening 10, a group of mounting columns 11 are symmetrically fixedly connected to the inner walls of the two clamping shells 9, and a wiping cotton 12 is fixedly connected between the two groups of mounting columns 11 in each clamping shell 9, and an intermittent liquid supply mechanism is provided on the top of the two mounting frames 7, and the intermittent liquid supply mechanism is used to intermittently transport cleaning agent into the wiping cotton 12;

[0044] A guide mechanism is provided between the two mounting racks 7 and the inner wall of the cleaning box 2, and the guide mechanism is used to limit the moving track of the mounting rack 7. A cleaning mechanism is provided on the inner bottom surface of the cleaning box 2. After the two wiping cottons 12 wipe the dirt on the surface of the insertion part of the digestive endoscope 13, the cleaning mechanism is used to clean the wiping cottons 12. A controller 14 is fixedly connected to the side wall of the cleaning box 2;During work, when pre-cleaning the insertion part of the digestive endoscope 13 after use, most nurses hold the handheld part of the digestive endoscope 13 with one hand, and use the other hand to hold a gauze with a cleaning agent to wipe the surface of the insertion part from top to bottom, so as to wipe off the dirt visible to the naked eye on the outer surface of the digestive endoscope 13. In the process of wiping with the gauze by hand, the manual cleaning method is prone to uneven force on the surface of the digestive endoscope 13 due to the negligence of the staff during the wiping process, resulting in incomplete cleaning. In addition, the process of soaking new gauze in advance for each cleaning is relatively cumbersome, and the whole process is not automated. The present technical solution can solve the above problems. The specific implementation method is as follows: after the endoscopic examination, the digestive endoscope 13 is removed. The insertion portion is inserted and extended from the insertion hole 5 to the interior of the cleaning box 2, so that the insertion portion is located in the space between the two wiping cottons 12. The truncated cone-shaped setting of the insertion hole 5 is convenient for limiting the gripping of the hand-held part of the digestive endoscope 13. In the initial state, the two clamping shells 9 are both located at one end of the mounting frame 7 close to the inner wall of the cleaning box 2, so as to reserve enough space for the insertion portion of the digestive endoscope 13. After the digestive endoscope 13 is inserted, the first electric cylinder 8 on the inner wall of the two mounting frames 7 is operated by the controller 14. The piston rod of the first electric cylinder 8 will push the clamping shell 9 to move, and the two clamping shells 9 move toward the surface of the insertion portion of the digestive endoscope 13, so as to facilitate the contact between the side walls of the wiping cotton 12 on the clamping shell 9 and the surface of the insertion portion of the digestive endoscope 13. Subsequently, the controller 14 controls the operation of the driving mechanism, and the driving mechanism drives the two support plates 6 to slide down along the inner wall of the cleaning box 2, and the mounting frame 7 is pulled down by the sliding support plate 6. The provided guiding mechanism is convenient for limiting the moving trajectory of the mounting frame 7. During the downward movement of the mounting frame 7, the intermittent liquid supply mechanism is linked to intermittently transport cleaning agent into the wiping cotton 12. Therefore, during the downward movement of the mounting frame 7, the two wiping cottons 12 in contact with the insertion part of the digestive endoscope 13 are intermittently transported with cleaning agent, which is conducive to the wiping cotton 12 to stably clean the dirt on the surface of the insertion part of the digestive endoscope 13 as the mounting frame 7 moves downward, and is conducive to uniform force on the surface of the insertion part of the digestive endoscope 13, so that the wiping cotton 12 can be wiped more thoroughly, thereby facilitating the digestive endoscope 13 to be cleaned more thoroughly. The endoscope 13 is transported to the external cleaning and disinfection chamber for further cleaning and disinfection. The cleaned dirt will be discharged along the drainage pipe 4 at the bottom of the cleaning box 2. When the wiping cotton 12 is out of contact with the insertion part of the digestive endoscope 13, under the guidance of the guide mechanism, the mounting frame 7 is driven to slide along the top of the support plate 6, so that the wiping cotton 12 after wiping the dirt is guided to the cleaning station and stops. At this time, the controller 14 controls the cleaning mechanism to clean the surface of the wiping cotton 12, which is conducive to maintaining the clean state of the wiping cotton 12 and avoiding the phenomenon that the dirt after wiping is adsorbed on the surface of the wiping cotton 12. The whole process is more automatic and intelligent, and the wiping cotton 12 is automatically soaked and the wiping cotton 12 is automatically cleaned after wiping. ;

[0045] As an embodiment of the present invention, a clamping mechanism is symmetrically provided on the top of the box cover 3, and the clamping mechanism is used to clamp the digestive endoscope 13 that needs to be cleaned. The clamping mechanism includes a first mounting groove 15, and the first mounting groove 15 is opened on the top of the box cover 3. A second electric cylinder 16 is fixedly connected to the inner wall of the first mounting groove 15, and a clamping plate 17 is fixedly connected to the end of the piston rod of the second electric cylinder 16. A rubber pad 18 is fixedly connected to the end of the clamping plate 17. The second electric cylinder 16 is electrically connected to the controller 14; when working, the digestive endoscope 13 that needs to be cleaned is clamped. After the insertion part of the digestive endoscope 13 is inserted into the cleaning box 2 from the insertion hole 5, the second electric cylinder 16 is started by the controller 14, and the piston rod of the second electric cylinder 16 will push the clamping plate 17 connected with the rubber pad 18 to move toward the handle of the digestive endoscope 13, so as to clamp the digestive endoscope 13. The rubber pad 18 is made of elastic rubber material, which is conducive to alleviating the rigid force of the clamping plate 17 on the digestive endoscope 13, thereby avoiding damage to the clamped part of the digestive endoscope 13 during the clamping process.

[0046] As an embodiment of the present invention, the driving mechanism includes a pulling plate 19 and a first motor 20. The pulling plate 19 is fixedly connected to the bottom of the two support plates 6. A threaded hole 1901 is formed through the top of the pulling plate 19. The first motor 20 is fixedly connected to the top of the box cover 3. The first motor 20 is electrically connected to the controller 14. The output shaft end of the first motor 20 passes through the box cover 3 and extends to the inside of the cleaning box 2 and is fixedly connected to a threaded rod 21. The lower end of the threaded rod 21 passes through the threaded hole 1901 and extends downward to be rotatably connected to the inner bottom surface of the cleaning box 2. The threaded hole 1901 of the threaded rod 21 901 are threadedly connected; when working, the first motor 20 is started by the controller 14. The first motor 20 is a forward and reverse stepping motor. The output shaft of the first motor 20 will drive the threaded rod 21 to rotate. Since the threaded rod 21 is threadedly connected to the threaded hole 1901 on the pulling plate 19, when the threaded rod 21 rotates, the pulling plate 19 will be driven to slide downward along the surface of the threaded rod 21, thereby pulling the two support plates 6 to move downward, and the pulling plate 19 moves down to the lowest position. When the first motor 20 is controlled to reverse, the threaded rod 21 will be driven to rotate in the opposite direction, thereby driving the pulling plate 19 to move up and reset.

[0047] As an embodiment of the present invention, the intermittent liquid supply mechanism includes a plurality of circular holes 22, a conveying box 23, and two first mounting plates 25. The plurality of circular holes 22 are respectively penetrated through the tops of a plurality of mounting columns 11 located above the interior of the clamping shell 9. The conveying box 23 is fixedly connected to the top of the clamping shell 9. The bottom of the conveying box 23 is fixedly connected with a plurality of drainage pipes 24. The lower ends of the plurality of drainage pipes 24 penetrate the clamping shell 9 and extend into the interior thereof and are respectively inserted into the interiors of adjacent circular holes 22. The two first mounting plates 25 are symmetrically fixedly connected to the top of the mounting frame 7. A liquid storage tank 26 is commonly fixedly connected between the two first mounting plates 25. A mounting hole 27 is penetrated through the bottom of the liquid storage tank 26. A hose 28 is fixedly connected to the inner wall of the mounting hole 27. The lower end of the hose 28 is fixedly connected to the conveying box 23. A sealing mechanism is provided on the inner bottom surface of the liquid storage tank 26. The sealing mechanism is used to seal the top of the mounting hole 27. When the mounting bracket 7 is in the process of moving downward, the linkage blocking mechanism intermittently cancels the blocking of the mounting hole 27; when working, when the mounting bracket 7 moves downward along with the support plate 6, the linkage blocking mechanism cancels the blocking of the mounting hole 27, thereby facilitating the cleaning agent inside the liquid storage tank 26 to flow from the hose 28 in the mounting hole 27 to the inside of the delivery box 23, and enters the top of the wiping cotton 12 through the drainage pipe 24 at the bottom of the delivery box 23, thereby realizing the soaking of the wiping cotton 12, facilitating the wiping cotton 12 to wipe and clean the dirt on the insertion part of the digestive endoscope 13, without the need to manually soak the wiping cotton 12 during the wiping process, reducing the work intensity, and when the blocking mechanism resumes the blocking of the mounting hole 27, it will block the wetting of the wiping cotton 12 by the cleaning agent in the liquid storage tank 26, which is conducive to saving the use of cleaning agent during the wiping process and avoiding the occurrence of the phenomenon of cleaning agent waste caused by excessive cleaning agent flowing.

[0048] As an embodiment of the present invention, the blocking mechanism includes a slide bar 29, a blocking plate 32, and a rectangular plate 34.

[0049] As an embodiment of the present invention, a squeezing mechanism is provided inside the two clamping shells 9. When the wiping cotton 12 moves toward the surface of the insertion portion on the digestive endoscope 13, the squeezing mechanism is used to squeeze the adjacent wiping cotton 12. The squeezing mechanism includes an arc box 36 and two fixed shells 38. The arc box 36 is fixedly connected to the inner wall of the clamping shell 9. A mounting port 3601 is provided on the inner wall of the arc box 36. A rubber gasket 37 is fixedly connected to the inner wall of the mounting port 3601. The two fixed shells 38 are symmetrically fixedly connected to the inner wall of the mounting frame 7. The tops of the two fixed shells 38 are penetrated with second vents 39. The shell openings of the two fixed shells 38 are fixedly connected There is a cover plate 40, and the inner walls of the two fixed shells 38 are slidably connected with sliding boxes 41.

Two first ventilation holes 43 are provided on the side of the two sliding boxes 41 facing the cover plate 40. When working, when the two wiping cottons 12 move toward each other and contact the surface of the insertion part on the digestive endoscope 13, due to the softness of the wiping cottons 12 themselves, it is easy to cause the phenomenon of insufficient adhesion, thereby The above problem is affected by the wiping effect of the wiping cotton 12 on the dirt. The technical solution can solve the above problem. The specific implementation method is as follows. During the process of the first electric cylinder 8 pushing the clamping shell 9 to move, the moving clamping shell 9 drives the wiping cotton 12 to move toward the insertion surface of the digestive endoscope 13, and the arc box 36 connected to the inside of the clamping shell 9 will move along with it. The moving arc box 36 drives the air pipe 42 connected to the sliding box 41 to move, thereby driving the sliding box 41 to slide along the inner wall of the fixed shell 38. Since the side wall of the sliding box 41 is in sealing contact with the inner wall of the fixed shell 38, when the sliding box 41 slides toward one side of the cover plate 40 along with the air pipe 42, The internal space of the fixed shell 38 on one side of the sliding box 41 is compressed, so that the air flow between the sliding box 41 and the cover plate 40 enters the interior of the sliding box 41 through the first vent hole 43 and is transported to the arc box 36 through the air pipe 42. The air flow in the arc box 36 increases, and the air pressure becomes greater, thereby pushing the rubber gasket 37 to bulge under the action of the air pressure. The bulged rubber gasket 37 will push the wiping cotton 12 connected between the two groups of mounting columns 11, which is beneficial for the wiping cotton 12 to be in closer contact with the surface of the insertion part of the digestive endoscope 13, and then it is beneficial for the wiping cotton 12 to fully wipe the dirt on the surface of the insertion part of the digestive endoscope 13, thereby avoiding the occurrence of incomplete wiping.

In the initial state, the two clamping shells 9 are both located at one end of the mounting frame 7 close to the inner wall of the cleaning box 2, so as to reserve enough space for the insertion portion of the digestive endoscope 13. After the digestive endoscope 13 is inserted, the first electric cylinder 8 on the inner wall of the two mounting frames 7 is operated by the controller 14. The first The piston rod of the electric cylinder 8 will push the clamping shell 9 to move, and the two clamping shells 9 will move toward the surface of the insertion part of the digestive endoscope 13, so that the side wall of the wiping cotton 12 on the clamping shell 9 will contact the surface of the insertion part of the digestive endoscope 13. Then, the controller 14 will control the operation of the driving mechanism, and the driving mechanism will drive the two support plates 6 to slide down along the inner wall of the cleaning box 2, and the mounting frame 7 will be pulled down by the sliding support plate 6.
