Description

Technical Field

[0001] This application relates to the field of cleaning equipment, and particularly to a bedside automatic pre-cleaning system for digestive endoscopes. Background Art

[0002] A digestive endoscope is an endoscopic device used for observing, diagnosing, and treating digestive tract diseases. It can enter the human body through natural body cavities (such as the oral cavity and anus), directly obtain images of the digestive tract mucosa, and support operations such as biopsy and polyp resection. A digestive endoscope includes a light guide connection part, an operation part, and an insertion part. The light guide connection part is used to connect to an external host to transmit optical signals and image data. The insertion part is used to insert into the patient's body for diagnosis and treatment. After the diagnosis and treatment are completed, the insertion part needs to be removed from the patient's body, and then the endoscope should be disinfected in a timely manner. The disinfection steps include pretreatment - leak detection - enzymatic washing and brushing - disinfection and sterilization - drying - storage. Among them, the pretreatment operation needs to be carried out by nursing staff at the bedside to prevent the formation of a biofilm that is difficult to clean after mucus, blood, and other dirt attached to the endoscope body dries. After pretreatment, the nursing staff then removes the endoscope from the host and transfers it to the disinfection and cleaning room for subsequent disinfection treatment.

[0003] Regarding the pretreatment operation, the "Technical Specification for Cleaning and Disinfection of Flexible Endoscopes" requires that after the endoscope is removed from the patient's body and before being detached from the light source and video processor, the outer surface dirt should be wiped off immediately with a wet wipe or wet gauze containing a cleaning solution, and the wiping supplies should be used once; then, air and water should be sent repeatedly for at least 10 s; the tip of the endoscope should be placed in a container filled with a cleaning solution, and the suction function should be activated to aspirate the cleaning solution until it flows into the suction tube.

[0004] In the related art, a Chinese invention patent with the publication number CN117398049A discloses an endoscopic automatic bedside pretreatment system, which includes an enzyme solution machine and a main body bracket. The enzyme solution machine is used to configure enzyme solution, and a paper cup is placed at the bottom of the main body bracket for receiving the enzyme solution from the enzyme solution machine. The main body bracket is used to mount the endoscope, and a pretreatment actuator and a control system are provided on the main body bracket. The pretreatment actuator includes a housing, an air / water button guide shaft, a suction button guide shaft, and a first endoscope handle fixing seat. The control system includes a control screen and a recording module. When preprocessing the used endoscope, the nursing staff first wipes the external surface dirt with a wet gauze containing enzyme solution, then places the operation part of the endoscope on the first endoscope handle fixing seat, places the distal end part of the endoscope in the paper cup, then clicks the control screen with the hand to run the recording module, and then picks up the endoscope configuration information card and swipes it on the recording module to record information such as the operation process, diagnosis and treatment date, and endoscope number. At this time, the enzyme solution machine fills the paper cup with enzyme solution, and the pretreatment actuator automatically presses the air supply and water supply buttons on the endoscope operation part to perform repeated air supply and water supply to the endoscope for at least 10 s, and then the pretreatment actuator automatically presses the suction function button to aspirate the enzyme solution until it flows into the suction bottle, thus completing the automatic air supply, water supply, and suction process of the endoscope. In view of the above related art, the inventors found that although the automatic air supply, water supply, and suction processes in the pretreatment requirements for the endoscope can be achieved through this pretreatment system, the wiping and cleaning of the endoscope surface still need to be manually operated by the nursing staff. During the operation, on the one hand, due to the long length of the endoscope, it is inconvenient for the nursing staff to wipe it completely from top to bottom, and there is also a problem that the wiping is not clean due to non-standard actions. On the other hand, after the wiping is completed, the nursing staff needs to isolate the contact with the operation screen and the endoscope configuration information card with a clean gauze, but in actual work, the nursing staff may forget this step and directly touch with the hand after wiping the endoscope, which may cause some bacteria to adhere to the operation screen and the endoscope configuration information card, increasing the possibility of cross-infection. Summary of the Invention

[0005] To solve the above problems, the present application provides a bedside automatic pre-cleaning system for digestive endoscopes.

[0006] The bedside automatic pre-cleaning system for digestive endoscopes provided by the present application adopts the following technical solutions: A bedside automatic pre-cleaning system for a digestive endoscope, comprising a pretreatment bracket and an enzyme solution machine. A pretreatment execution module and a control module are arranged at the top of the pretreatment bracket, and the two are respectively located on opposite sides of the pretreatment bracket. The pretreatment execution module is used for mounting the operation part of the endoscope and performing automatic air supply, water supply and suction operations on the endoscope. A card-swipping area is arranged on the control module, and the card-swipping area is used for swiping an endoscope configuration information card. The control module is electrically connected to the pretreatment execution module. The pretreatment bracket comprises a moving box and a suspension rod. The suspension rod is vertically arranged on the moving box. A clamp is vertically slidably connected to the suspension rod. The clamp can be opened or tightened. Two wiping assemblies are respectively arranged at both ends of the clamp. The wiping assembly comprises a detachable disposable enzyme solution sponge block. The two disposable enzyme solution sponge blocks are used for clamping and wiping the insertion part of the endoscope. A driving mechanism is arranged in the suspension rod, and the driving mechanism is used for driving the clamp to slide up and down. The control module is electrically connected to the driving mechanism. A placement plate is vertically slidably connected to the enzyme solution machine. A disposable enzyme solution box is placed on the placement plate. A displacement mechanism for driving the placement plate to move is arranged in the enzyme solution mechanism.

[0007] By adopting the above technical solution, after the diagnosis and treatment is completed and before the endoscope is detached from the light source and the video processor, the nursing staff takes over the endoscope, holds the operation part of the endoscope and mounts it on the pretreatment execution module. At this time, the clamp is in an open state and is located at the top of the insertion part of the endoscope. The insertion part of the endoscope is located between the two wiping assemblies. Then, the nursing staff swipes the endoscope configuration information card in the card-swipping area, the control module is started, the control module controls the clamp to close, the two disposable enzyme solution sponge blocks contact and clamp the insertion part of the endoscope, and then the driving mechanism is started. The driving mechanism drives the clamp to move from top to bottom, and the two disposable enzyme solution sponge blocks wipe the insertion part of the endoscope from top to bottom. Thus, the automatic wiping of the insertion part of the endoscope can be completed without the nursing staff's contact, minimizing the contact between the nursing staff and the contaminated area of the endoscope as much as possible, thereby preventing the nursing staff from transferring the bacteria on the endoscope to the cleaning equipment and reducing the possibility of cross-infection. At the same time, the automatic wiping is more uniform and convenient than manual wiping, improving the efficiency and comprehensiveness of wiping and cleaning. After the wiping is completed, the clamp opens, and the driving mechanism drives the clamp to rise a certain distance. At this time, the enzyme solution machine has filled the disposable enzyme solution box with a fixed amount of enzyme solution. Then, the displacement mechanism drives the placement plate to move to directly below the insertion part of the endoscope, and then drives the placement plate to move up a certain distance, so that the tip of the endoscope is inserted into and immersed in the enzyme solution in the disposable enzyme solution box. The control module controls the pretreatment execution module to press the air supply and water supply buttons on the operation part of the endoscope, perform repeated air supply and water supply on the endoscope for at least 10 s, and then automatically press the suction function button to suck the enzyme solution until it flows into the suction bottle, completing the air supply, water supply and suction processes of the endoscope.

[0008] Optionally, a lifting groove is provided at one end of the moving box in the length direction of the top surface. The suspension rod is vertically and slidably connected in the lifting groove. A foot-operated adjustment assembly and a locking assembly are provided in the moving box. The foot-operated adjustment assembly can be used to drive the suspension rod to move upward. The locking assembly can lock or unlock the suspension rod. An indicating line is marked on the suspension rod in the vertical direction. When the indicating line is aligned with the top surface of the moving box, it can be used to indicate the height of the suspension rod.

[0009] By adopting the above technical solution, since the digestive endoscope includes various types and the lengths of different types of endoscopes are also different, in order to make the suspension rod adaptable to endoscopes of different lengths, the suspension rod is set in a height-adjustable form. The nursing staff can adjust the height of the suspension rod by stepping on the foot-operated adjustment assembly with their feet, and then the locking assembly locks it. The height to be adjusted can be quickly determined through the indicating line on the suspension rod, so that it can be applicable to digestive endoscopes of different lengths and improve the applicable range of the device. At the same time, by adjusting in a foot-stepping manner, on the one hand, it is convenient for the nursing staff to adjust, and on the other hand, it reduces the contact with the hands of the nursing staff and reduces the possibility of bacteria spreading between the device and the endoscope through hand contact, thereby also reducing the possibility of cross-infection.

[0010] Optionally, the inside of the suspension rod is hollow and open at the bottom. The driving mechanism includes a driving belt. The driving belt is set in an L shape. The top of the driving belt is located inside the suspension rod, and the bottom is located inside the moving box. A pulley is rotatably connected inside the suspension rod to tension one end of the driving belt. Three pulleys are rotatably connected inside the moving box to tension the other end of the driving belt and the inner and outer side walls at the corner of the driving belt. The pulley located inside the moving box away from the suspension rod is movable. A locking bolt is provided on the moving box, and the locking bolt is used to lock the movable pulley. A first driving motor is also provided inside the moving box, and the first driving motor is used to drive one of the fixed pulleys to rotate. A chute is vertically provided on one side of the suspension rod and the moving box facing the pretreatment execution module. A fixed rod is fixedly connected to the driving belt, and the fixed rod extends out of the chute and is fixedly connected to the jaw.

[0011] By adopting the above technical solution, when wiping the insertion part of the endoscope, the control module controls the first driving motor to start. The first driving motor drives the driving belt to rotate. The driving belt drives the jaw to move from top to bottom through the fixed rod, so as to complete the automatic wiping of the insertion part of the endoscope. At the same time, since the height of the suspension rod is adjustable, a movable pulley is provided, so that the top end of the driving belt can rise and fall with the rise and fall of the suspension rod, the other end is movable, and is locked by the locking bolt, so that it can adapt to suspension rods of different heights and improve the applicable range of the device.

[0012] Optionally, guide grooves are formed on two opposite inner walls of the moving box. The guide grooves are horizontally arranged. Sliders are slidably connected in the two guide grooves respectively. A rotating shaft is fixedly connected between the two sliders. The axial direction of the rotating shaft is perpendicular to the length direction of the suspension rod. The movable pulley is coaxially and rotatably connected to the rotating shaft. A linkage rod is rotatably connected between the bottom of the suspension rod and the rotating shaft. The end of the suspension rod connected to the linkage rod is higher than the end connected to the rotating shaft. The guide groove facing the front of the moving box is open. The locking bolt is threadedly connected to the slider in the open guide groove.

[0013] By adopting the above technical solution, when the height of the suspension rod needs to be adjusted, first loosen the locking bolt, and then raise the suspension rod. During the raising process, the suspension rod drives the movable pulley to move towards the suspension rod through the linkage rod. When the adjustment is completed, tighten the driving belt and tighten the locking bolt to complete the tensioning of the driving belt; through the linkage of the suspension rod and the driving belt, the adaptability adjustment of the driving belt can be completed while raising the suspension rod, and the operation is simple and convenient.

[0014] Optionally, the foot pedal adjustment assembly includes a lever arranged in the moving box. A gear is fixedly connected to one end of the lever close to the suspension rod. A rack is vertically arranged at the bottom of the suspension rod. The gear is used to mesh with the rack. The other end of the lever is rotatably connected to a first guide rod. First guide chutes are formed on the inner walls at both ends in the width direction of the moving box. Both ends of the first guide rod are slidably connected in the two first guide chutes respectively. The axial direction of the first guide rod is parallel to the width direction of the moving box. The upper part of the first guide chute is vertically arranged, and the lower part is arc-shaped. Guide blocks are fixedly connected to the inner walls at both ends in the width direction of the moving box. Second guide chutes are formed on the guide blocks. A second guide rod is coaxially fixedly connected to the gear. The axial direction of the second guide rod is parallel to the axial direction of the first guide rod. Both ends of the second guide rod are slidably connected in the two second guide chutes respectively. The second guide chute is arc-shaped and the concave surface faces the first guide chute. The concave surface of the lower arc of the first guide chute faces the second guide chute and the arc is centered on the center of the bottom end of the second guide chute. A driving rod is fixedly connected to the first guide rod. A limiting groove is vertically formed on one side of the moving box away from the suspension rod. The other end of the driving rod extends out of the limiting groove and is fixedly connected to a height-adjusting pedal. The driving rod can slide in the limiting groove. A return spring is arranged between one end of the lever close to the first guide rod and the inner wall of the top of the moving box.

[0015] By adopting the above technical solution, when adjusting the suspension rod upwards, step on the height-adjusting pedal downwards, which drives the driving rod to slide downwards. The driving rod drives the first guiding rod to slide along the first guiding slideway. The first guiding rod drives the end of the shifting rod connected thereto to slide downwards. The shifting rod drives the second guiding rod to slide within the second guiding slideway. When it slides to the bottom end of the second guiding slideway, the gear meshes with the rack. The end of the shifting rod connected to the first guiding rod rotates downwards, and the meshing part of the gear and the rack rotates upwards, thereby pushing the rack to move upwards by a certain distance, that is, driving the suspension rod to move upwards by a certain distance. The caregiver can quickly judge the height to be adjusted according to the indication line on the suspension rod, so as to conveniently adjust the height of the suspension rod. After the adjustment is completed, lock the rack through the locking assembly to complete the fixation of the suspension rod.

[0016] Optionally, the locking assembly includes a locking pawl arranged below the gear. The bottom of the locking pawl is fixedly connected with a rotating rod. The rotating rod extends out of the moving box and is rotatably connected to the moving box. The top of the locking pawl is used for clamping the rack. An unlocking pedal is arranged at one end of the rotating rod extending out of the moving box. A fixing plate is fixedly connected to the outer side wall of the moving box. The fixing plate is located below the unlocking pedal. A support spring is arranged between the fixing plate and the unlocking pedal. The support spring is located at one end of the unlocking pedal away from the locking pawl.

[0017] By adopting the above technical solution, when stepping on the height-adjusting pedal, the gear drives the rack to move upwards, and the top of the pawl is forced to rotate away from the rack, thereby unlocking the rack and enabling the rack to slide upwards; when the rack stops sliding, the unlocking pedal is reset under the action of the support spring, driving the pawl to rotate towards the rack again, thereby locking the rack again; when it is necessary to lower the suspension rod to its original position, step on the unlocking pedal, so that the pawl rotates away from the rack, thereby unlocking the rack and enabling the suspension rod to slide downwards, so that the locking and unlocking of the suspension rod can be simply and quickly realized.

[0018] Optionally, the clamping jaws include a first connecting rod, a second connecting rod, two third connecting rods, two clamping rods and a retracting and extending cylinder. The first connecting rod is fixedly connected to the fixed rod. The two clamping rods are respectively rotatably connected to both ends of the first connecting rod. The retracting and extending cylinder is installed inside the first connecting rod. The telescopic shaft of the first connecting rod is fixedly connected to the second connecting rod. The two third connecting rods are rotatably connected between the adjacent clamping rod and the second connecting rod. The wiping assembly is arranged on the side of the clamping rod facing the other clamping rod. The wiping assembly includes a clamping box. The bottom surface and the side facing the other clamping box of the clamping box are open. The clamping box is used for clamping a disposable enzyme solution sponge block. The area of the opening at the bottom surface of the clamping box is smaller than that of the top.

[0019] By adopting the above technical solution, before wiping the endoscope, the retracting and extending cylinder extends to drive the jaws to open, and there is a space between the two wiping assemblies, facilitating the insertion of the insertion part of the endoscope; when it is necessary to wipe the insertion part of the endoscope, the retracting and extending cylinder is contracted to drive the two clamping rods to rotate towards each other, so that the two wiping assemblies rotate towards each other, and the two disposable enzyme solution sponge blocks come into contact to clamp the insertion part of the endoscope. The two disposable enzyme solution sponge blocks completely wrap the peripheral side wall of the insertion part of the endoscope, thereby improving the comprehensiveness and uniformity during wiping; at the same time, the area of the bottom opening of the snap-in box is smaller than that of the top, which can ensure the stability of the disposable enzyme solution sponge block during snap-in and prevent it from falling during the wiping process.

[0020] Optionally, the wiping assembly further includes a connecting box, the connecting box is fixedly connected to the clamping rod, the snap-in box is fixedly connected to the bottom surface of the connecting box, a push plate is vertically slidably connected in the connecting box, a groove is provided in the top of the snap-in box corresponding to the push plate for the push plate to pass through, a push rod is fixedly connected to the top surface of the push plate, the push rod is vertically arranged and its top end extends out of the connecting box, a pressing plate is fixedly connected to the top end of the push rod, and a pressing spring is arranged between the pressing plate and the top surface of the connecting box.

[0021] By adopting the above technical solution, after the wiping is completed, when it is necessary to remove the disposable enzyme solution sponge block, press down the two pressing plates. The pressing plates drive the push plate to push the disposable enzyme solution sponge block downward through the push rod, so that it is separated from the snap-in box, thus facilitating the removal of the contaminated disposable enzyme solution sponge block without contact, enabling it to directly fall into the medical waste trash can, reducing the contact between the hands of the nursing staff and the contaminated consumables, and reducing the possibility of cross-infection.

[0022] Optionally, the displacement mechanism includes a sliding plate vertically slidably connected in the lower housing of the enzyme solution machine. A second driving motor and a driving lead screw are arranged in the lower housing of the enzyme solution machine. The driving lead screw is axially vertical and is threadedly connected to the sliding plate. The second driving motor is used to drive the driving lead screw to rotate. A telescopic cylinder is installed on the sliding plate. A displacement groove is vertically opened on the front surface of the enzyme solution machine housing. The telescopic shaft of the telescopic cylinder extends out of the displacement groove and is fixedly connected to the placement plate. A snap-in plate is arranged on the placement plate, and the disposable enzyme solution box is snap-connected into the snap-in plate.

[0023] By adopting the above technical solution, the enzyme solution machine fills a quantitative enzyme solution into the disposable enzyme solution box. After the wiping is completed, the telescopic cylinder extends to drive the disposable enzyme solution box to move directly below the insertion part of the endoscope. At the same time, the second driving motor drives the driving lead screw to rotate, and the driving lead screw drives the sliding plate to move upward by a certain distance, so that the tip of the endoscope is inserted into and immersed in the enzyme solution of the disposable enzyme solution box for subsequent air supply, water supply, and suction processes; the position of the disposable enzyme solution box can be conveniently adjusted through the displacement mechanism, so as to more quickly and accurately align with the insertion part of the endoscope.

[0024] Optionally, the bottom area of the disposable enzyme solution sponge block shrinks, and the top opening of the disposable enzyme solution cartridge expands and is adapted to the bottom shape when contacting the two disposable enzyme solution sponge blocks.

[0025] By adopting the above technical solution, when the distal end of the endoscope is inserted into the enzyme solution, the clamping jaws can move upward by a certain distance to clamp the insertion part of the endoscope again. Then, as the disposable enzyme solution cartridge rises, since the bottom shape of the top of the disposable enzyme solution cartridge is adapted to the two disposable enzyme solution sponge blocks when contacting them, the bottoms of the two disposable enzyme solution sponge blocks can be inserted into the disposable enzyme solution cartridge to block it, effectively preventing the aerosol in the disposable enzyme solution cartridge from escaping during the air supply, water supply and aspiration operations of the endoscope, thereby reducing the possibility of cross-infection; and after the aspiration is completed, press down the pressing plate. Since the top opening of the disposable enzyme solution cartridge expands, the disposable enzyme solution sponge block can directly fall into the disposable enzyme solution cartridge, avoiding contact with the contaminated disposable enzyme solution sponge block. Then, the second driving motor drives the sliding plate to descend until the distal end of the endoscope disengages from the disposable enzyme solution cartridge, and then the disposable enzyme solution cartridge is removed from the placement plate, so that the two can be thrown into the medical waste trash can together, which is convenient for unified treatment.

[0026] In summary, the present application includes at least one of the following beneficial technical effects: 1. After the diagnosis and treatment are completed and before the endoscope is detached from the light source and the video processor, the nursing staff takes over the endoscope, holds the operation part of the endoscope and mounts it on the pretreatment execution module. The driving mechanism drives the clamping jaws to move from top to bottom, and the two disposable enzyme solution sponge blocks wipe the insertion part of the endoscope from top to bottom. Thus, the automatic wiping of the insertion part of the endoscope can be completed without the nursing staff's contact, minimizing the contact between the nursing staff and the contaminated area of the endoscope as much as possible, thereby preventing the nursing staff from transferring the bacteria on the endoscope to the cleaning equipment and reducing the possibility of cross-infection. At the same time, the automatic wiping is more uniform and convenient than manual wiping, improving the efficiency and comprehensiveness of wiping and cleaning; 2. Since there are various types of digestive endoscopes and the lengths of different types of endoscopes are different, in order to make the suspension rod adaptable to endoscopes of different lengths, the suspension rod is set in a height-adjustable form. The nursing staff can adjust the height of the suspension rod by stepping on the foot pedal adjustment component, and then the locking component locks it, and quickly determines the height to be adjusted through the indication line on the suspension rod, so that it can be applicable to digestive endoscopes of different lengths, improving the applicable range of the device; 3. After the wiping is completed and the disposable enzyme solution sponge block holder needs to be removed, press down on the two pressing plates. The pressing plates drive the push plate downward through the push rods to push the disposable enzyme solution sponge block downward, so that it disengages from the clamping box, thus facilitating the removal of the contaminated disposable enzyme solution sponge block without contact, reducing the contact between the hands of the nursing staff and the contaminated consumables, and reducing the possibility of cross-infection.

[0029] The following Figures 1-5 further elaborates on this application in detail.

[0030] The embodiment of this application discloses a bedside automatic pre-cleaning system for a digestive endoscope.

[0031] Refer to Figure 1 and Figure 2, A bedside automatic pre - cleaning system for digestive endoscopes includes a pretreatment bracket 1 and an enzyme solution machine 2. The pretreatment bracket 1 is used to mount the endoscope 3 and perform automatic wiping, air and water supply, and suction operations on it. The enzyme solution machine 2 is used to provide enzyme solution. The pretreatment bracket 1 includes a suspension rod 11 and a moving box 12. The suspension rod 11 is vertically slidably connected to the moving box 12. A height - adjusting mechanism is provided inside the moving box 12 to adjust the height of the suspension rod 11, so as to mount digestive endoscopes 3 of different lengths. The suspension rod 11 is hollow inside and has an opening at the bottom. An automatic wiping mechanism 15 is vertically slidably connected to the suspension rod 11 to automatically wipe the surface of the insertion part 32 of the endoscope 3. A driving mechanism 16 is provided inside the moving box 12 to drive the automatic wiping mechanism 15 to slide vertically. A control module 17 and a pretreatment execution module 18 are installed at the top of the suspension rod 11. A card - swiping area 171 is provided on the control module 17. The card - swiping area 171 is used to swipe the endoscope 3 configuration information card to record endoscope information and cleaning information. The pretreatment execution module 18 is used to mount the operation part 31 of the endoscope 3 and perform automatic air and water supply and suction operations on it. The control module 17 is electrically connected to the driving mechanism 16, the automatic wiping mechanism 15, and the pretreatment execution module 18 to control the operation of the three. The bottom of the enzyme solution machine 2 is provided with a displacement mechanism 21 and a placement plate 22. The placement plate 22 is used to place a disposable enzyme solution box 23. The displacement mechanism 21 is used to drive the placement plate 22 to move in the front - rear direction or the vertical direction, so as to conveniently adjust the position of the disposable enzyme solution box 23 according to the position of the endoscope 3.

[0032] Before the end of the diagnosis and treatment, the nursing staff first determines the height that the suspension rod 11 needs to be adjusted according to the type of the endoscope 3 used in the diagnosis and treatment, and then drives the height - adjusting mechanism by stepping on it. The height - adjusting mechanism drives the suspension rod 11 to rise and fall, so as to adjust it to a suitable height. After the end of the diagnosis and treatment, before the endoscope 3 is detached from the light source and the video processor, the nursing staff takes over the endoscope 3, mounts the operation part 31 of the endoscope 3 on the pretreatment execution module 18. At this time, the automatic wiping mechanism 15 is located at the top of the insertion part 32 and clamps it. The endoscope 3 hangs naturally. The nursing staff swipes the endoscope 3 configuration information card at the card - swiping area 171, and the control module 17 is activated. The control module 17 controls the driving mechanism 16 to operate, and the driving mechanism 16 controls the automatic wiping mechanism 15 to slide downwards, so as to wipe the insertion part 32 of the endoscope 3 along the direction from far away from the distal end to close to the distal end.

[0033] During the wiping process, the enzyme solution machine 2 fills a quantitative enzyme solution into the disposable enzyme solution cartridge 23. After the wiping is completed, the automatic wiping mechanism 15 releases the distal end of the endoscope 3, and the displacement mechanism 21 of the enzyme solution machine 2 drives the placement plate 22 to move forward in front of the enzyme solution machine 2 until it aligns with the insertion portion 32 of the endoscope 3, and then moves upward to soak the distal end of the endoscope 3 with the enzyme solution. Then, the pretreatment execution module 18 presses the air supply and water supply buttons on the operation portion 31 of the endoscope 3 to perform repeated air supply and water supply to the endoscope 3 for at least 10 s, and then automatically presses the suction function button to aspirate the enzyme solution until it flows into the suction bottle, completing the air supply, water supply and suction processes of the endoscope 3.

[0034] Refer to Figure 1 , a locking wheel 121 is installed at the bottom of the moving box 12, which can facilitate the movement and locking of the moving box 12. The length direction of the moving box 12 is horizontally arranged, the suspension rod 11 is located at one end of the moving box 12 in the length direction, the suspension rod 11 is vertically arranged, and a lifting groove 122 is formed on one side of the top surface of the moving box 12 close to the enzyme solution machine 2. The suspension rod 11 is vertically slidably connected in the lifting groove 122. The length direction of the placement plate 22 is parallel to the length direction of the moving box 12.

The foot pedal adjustment component 13 includes a height adjustment pedal 133, a driving rod 131, a lever 134, a gear 1351 and a rack 1352. The driving rod 131 is vertically and slidably connected in the moving box 12. The driving rod 131 is arranged in an L shape. A first guide rod 132 is fixedly connected to the top end of the driving rod 131, and the other end extends out of the moving box 12 and is fixedly connected to the height adjustment pedal 133. The height adjustment pedal 133 is located on the side of the moving box 12 away from the enzyme solution machine 2. First guide chutes 123 are provided on the inner side walls at both ends in the width direction of the moving box 12. The upper part of the first guide chute 123 is vertically provided, and the lower part is arc-shaped. Both ends of the first guide rod 132 are respectively inserted into the adjacent first guide chutes 123 and slidably connected in the first guide chutes 123. The axial direction of the first guide rod 132 is parallel to the width direction of the moving box 12. A limiting groove 124 is vertically provided on the side of the moving box 12 away from the enzyme solution machine 2. The end of the driving rod 131 fixedly connected to the height adjustment pedal 133 is slidably connected in the limiting groove 124.

[0036] Refer to Figure 1 and Figure 2, the shift lever 134 is located between the drive lever 131 and the suspension rod 11. One end of the shift lever 134 is rotatably connected to the first guide rod 132, and the other end is fixedly connected to the gear 1351. The rack 1352 is fixedly connected to the side of the suspension rod 11 facing the gear 1351 and meshes with the gear 1351. The length direction of the rack 1352 is parallel to the length direction of the suspension rod 11. Guide blocks 136 are fixedly connected to the inner walls at both ends in the width direction of the moving box 12. Second guide chutes 1361 are provided on the guide blocks 136. A second guide rod 137 is coaxially and fixedly connected to the gear 1351. The axis of the second guide rod 137 is parallel to the axis of the first guide rod 132. Both ends of the second guide rod 137 are slidably connected to the two second guide chutes 1361 respectively. The second guide chute 1361 is set to be arc-shaped and the concave surface faces the drive lever 131. The end of the second guide chute 1361 close to the drive lever 131 is higher than the end close to the rack 1352 and lower than the top end of the first guide chute 123. The shapes of both ends of the second guide chute 1361 are set to be semi-circular for fitting with the circumferential side wall of the second guide rod 137. The arc at the lower part of the first guide chute 123 is set with the center of the bottom end of the second guide chute 1361 as the center. A return spring 138 is fixedly connected between the inner top wall of the moving box 12 and the shift lever 134. The return spring 138 is located at the end of the shift lever 134 close to the first guide rod 132. In addition, for facilitating the viewing of the height adjustment distance of the suspension rod 11, indicating lines 139 are marked on the front of the suspension rod 11 in the vertical direction. When the indicating line 139 is aligned with the top surface of the moving box 12, the height of the suspension rod 11 at this time can be displayed, so as to quickly and accurately adjust to the corresponding height according to the lengths required by different endoscopes 3.

[0037] When the return spring 138 is in a normal state, the end of the shift lever 134 close to the first guide rod 132 is clamped at the top end of the first guide chute 123 under the pulling force of the return spring 138. At this time, the second guide rod 137 is clamped at the top end of the second guide chute 1361, the gear 1351 is disengaged from the rack 1352, the end of the shift lever 134 connected to the first guide rod 132 is higher than the end connected to the second guide rod 137, and the end of the drive lever 131 fixed with the height adjustment pedal 133 is clamped at the top end of the limit groove 124.

[0038] When it is necessary to raise the suspension rod 11, step on the height-adjusting pedal 133 downward to drive the driving rod 131 to slide downward. The driving rod 131 drives the first guiding rod 132 to slide along the first guiding slideway 123. The first guiding rod 132 drives the lever 134 to slide downward at the end connected thereto. When the first guiding rod 132 slides on the vertical part of the first guiding slideway 123, the lever 134 drives the second guiding rod 137 to slide from the top end to the bottom end of the second guiding slideway 1361. When the first guiding rod 132 slides to the junction of the vertical part and the arc part of the first guiding slideway 123, the lever 134 is horizontally arranged. At this time, the second guiding rod 137 also slides to the bottom end of the second guiding slideway 1361, and the gear 1351 meshes with the rack 1352. At this time, continue to step on the height-adjusting pedal 133. The first guiding rod 132 enters the arc part of the first guiding slideway 123. Since the second guiding rod 137 has reached the bottom end of the second guiding slideway 1361, at this time, the lever 134 will rotate around the center of the bottom end of the second guiding slideway 1361. The end of the lever 134 connected to the first guiding rod 132 rotates downward, and the meshing part of the gear 1351 and the rack 1352 rotates upward, thereby pushing the rack to move upward by a certain distance, that is, driving the suspension rod 11 to move upward by a certain distance. At this time, the locking assembly 14 locks the bottom of the rack 1352 to complete a height-adjusting action.

[0039] When the height-adjusting pedal 133 is stepped on until the first guiding rod 132 reaches the bottom of the first guiding slideway 123, the driving rod 131 also moves horizontally until the height-adjusting pedal 133 abuts against the moving box 12. At this time, release the height-adjusting pedal 133. The return spring 138 pulls the lever 134 to reset. The first guiding rod 132 slides upward to the top end of the first guiding slideway 123, and the second guiding rod 137 slides upward to the top end of the second guiding slideway 1361, driving the gear 1351 to disengage from the rack 1352. The driving rod 131 slides upward to the top end of the limiting groove 124. After stepping on the height-adjusting pedal 133 several times, adjust the suspension rod 11 to the appropriate height. At this time, the locking assembly 14 locks the suspension rod 11.

[0040] Refer to Figure 3, the locking assembly 14 includes a locking pawl 141 and an unlocking pedal 143. The locking pawl 141 is disposed below the gear 1351 and is used for engaging with the rack 1352. The bottom end of the locking pawl 141 is fixedly connected to a rotating rod 142. The rotating rod 142 extends out of the moving box 12 and is rotatably connected to the moving box 12. The axial direction of the rotating rod 142 is parallel to the axial direction of the first guide rod 132. One end of the unlocking pedal 143 in the length direction is fixedly connected to the end of the rotating rod 142 extending out of the moving box 12. A fixing plate 144 is fixedly connected to the outer side wall of the moving box 12. The fixing plate 144 is located below the unlocking pedal 143. A support spring 145 is fixedly connected between the fixing plate 144 and the unlocking pedal 143. The support spring 145 is located at one end of the unlocking pedal 143 away from the locking pawl 141. In addition, in order to prevent the caregiver from accidentally touching the unlocking pedal 143, the unlocking pedal 143 can be arranged on the back of the moving box 12.

[0041] When the support spring 145 is in a normal state, the unlocking pedal 143 is in a state where one end close to the pawl is inclined downward. The rotating rod 142 drives the pawl to rotate in the direction close to the rack 1352, so that the top end of the pawl engages with the rack 1352, thereby locking the rack 1352. When stepping on the height-adjusting pedal 133, the gear 1351 drives the rack 1352 to move upward. The top of the pawl is forced to rotate in the direction away from the rack 1352, thereby unlocking the rack 1352 and enabling the rack 1352 to slide upward. After the rack 1352 stops sliding, the unlocking pedal 143 is reset under the action of the support spring 145, driving the pawl to rotate again in the direction close to the rack 1352, thereby locking the rack 1352 again. At this time, the gear 1351 disengages from the rack 1352. When it is necessary to lower the suspension rod 11 to its original position, step on the unlocking pedal 143 to make the pawl rotate away from the rack 1352, thereby unlocking the rack 1352 and enabling the suspension rod 11 to slide down.

[0042] Refer to Figure 2 , the driving mechanism 16 includes a first driving motor 161, a driving belt 162, and four belt pulleys 163. The driving belt 162 is arranged in an L shape, with the upper part located inside the suspension rod 11 and the lower part located inside the moving box 12. The four belt pulleys 163 are respectively used for fitting the inner and outer side walls at both ends and the corner of the driving belt 162. One of them is rotatably connected to the top inside the suspension rod 11, and the other three are rotatably connected to the bottom inside the moving box 12.

[0043] Refer to Figure 1 and Figure 2, the pulley 163 away from the suspension rod 11 is a movable pulley 163, and the other three are fixed pulleys 163. A rotating shaft 164 is coaxially and rotatably connected inside each of the fixed pulleys 163. One rotating shaft 164 is fixedly connected to the inside of the suspension rod 11, and the other two rotating shafts 164 are fixedly connected to the inside of the moving box 12. A rotating shaft 164 is also coaxially and rotatably connected inside the movable pulley 163. The axes of the four rotating shafts 164 are all parallel to the axis of the first guide rod 132. Both ends of the rotating shaft 164 of the movable pulley 163 are fixedly connected with sliders 165. Guide grooves 125 are opened on the inner side walls at both ends in the width direction of the moving box 12. The guide grooves 125 are opened along the length direction of the moving box 12. The two sliders 165 are respectively slidably connected in the corresponding guide grooves 125. The guide groove 125 on the front surface of the moving box 12 is open, and a locking bolt 166 is threadedly connected to the slider 165 therein. The locking bolt 166 is located outside the moving box 12. The locking bolt 166 is used to lock the slider 165 in the guide groove 125 to fix the position of the movable pulley 163. A linkage rod 167 is rotatably connected between the bottom of the suspension rod 11 and the rotating shaft 164 of the movable pulley 163. When the suspension rod 11 moves up and down, the locking bolt 166 can be loosened, so that the suspension rod 11 drives the rotating shaft 164 of the movable pulley 163 to slide along the guide groove 125 through the linkage rod 167, thereby realizing the adjustment of the position of the movable pulley 163, so that the driving belt 162 can change in cooperation with the height of the suspension rod 11.

[0044] Refer to Figure 1 and Figure 4 , the automatic wiping mechanism 15 includes a fixed rod 151, a clamping jaw 152 and two groups of wiping components 153. Chute grooves 111 are vertically opened on both the suspension rod 11 and the moving box 12 facing the side of the pretreatment execution module 18. The fixed rod 151 is fixedly connected to the side of the driving belt 162 close to the chute groove 111 and is slidably connected in the chute groove 111. The fixed rod 151 extends out of the chute groove 111 and is fixedly connected to the clamping jaw 152. The two groups of wiping components 153 are respectively located at both ends of the clamping jaw 152 and are used for clamping the insertion part 32 of the endoscope 3 and wiping it.

[0045] Refer to Figure 4, the jaw 152 includes a first connecting rod 1521, and the first connecting rod 1521 is fixedly connected to one end of the fixed rod 151 extending out of the sliding groove 111. The length direction of the fixed rod 151 is parallel to the length direction of the moving box 12, the length direction of the first connecting rod 1521 is perpendicular to the length direction of the fixed rod 151, and clamping rods 1522 are rotatably connected to both ends of the first connecting rod 1521. The two clamping rods 1522 are symmetrically arranged. A retracting cylinder 1525 is fixedly connected inside the first connecting rod 1521. The axis of the retracting cylinder 1525 is parallel to the length direction of the fixed rod 151. A second connecting rod 1523 is fixedly connected to the end of the telescopic shaft of the retracting cylinder 1525. The second connecting rod 1523 is located on the side of the first connecting rod 1521 away from the fixed rod 151 and is arranged parallel to it. Third connecting rods 1524 are rotatably connected to both ends of the second connecting rod 1523. The ends of the two third connecting rods 1524 away from each other are rotatably connected to the adjacent clamping rods 1522. The telescopic movement of the retracting cylinder 1525 can drive the second connecting rod 1523 to move away from or close to the first connecting rod 1521, thereby driving the two third connecting rods 1524 to move away from or close to each other, and further driving the two clamping rods 1522 to move away from or close to each other, finally opening or contracting the jaw 152.

[0046] Referring to Figure 4 , the wiping assembly 153 is located at the end of the clamping rod 1522 away from the first connecting rod 1521, and the two wiping assemblies 153 are respectively located on the sides of the two clamping rods 1522 facing each other. The wiping assembly 153 includes a connecting box 1531 and a clamping box 1532. The connecting box 1531 is fixedly connected to the side of the clamping rod 1522 facing each other. The clamping box 1532 is fixedly connected to the bottom surface of the connecting box 1531. The bottom surface and the side facing the other clamping box 1532 of the clamping box 1532 are open. A disposable enzyme sponge block 1533 is used to be clamped inside the clamping box 1532. The volume of the disposable enzyme sponge block 1533 is larger than the volume of the clamping box 1532, so that it protrudes from the clamping box 1532 in both the horizontal and vertical directions. To prevent the disposable enzyme sponge block 1533 from falling, the two ends of the bottom surface of the clamping box 1532 are inclined towards each other, so that the area of the opening at the bottom surface of the clamping box 1532 is smaller than the area of the top, and at the same time, the area of the bottom of the disposable enzyme sponge block 1533 also shrinks. A push plate 1534 is vertically slidably connected inside the connecting box 1531. A groove is provided at the top of the clamping box 1532 corresponding to the push plate 1534 for the push plate 1534 to pass through. Two push rods 1535 are fixedly connected to the top surface of the push plate 1534. The push rods 1535 are vertically arranged. The tops of the two push rods 1535 extend out of the connecting box 1531 and are fixedly connected through a pressing plate 1536. A pressing spring 1537 is fixedly connected between the pressing plate 1536 and the top surface of the connecting box 1531.

[0047] When it is necessary to wipe the insertion part 32 of the endoscope 3, take two disposable enzyme solution sponge blocks 1533, respectively insert them into the two clamping boxes 1532, and then contract the retracting cylinder 1525 to drive the two clamping rods 1522 to rotate towards each other, so that the two wiping assemblies 153 rotate towards each other, and the two disposable enzyme solution sponge blocks 1533 come into contact to clamp the insertion part 32 of the endoscope 3. When clamping, since the disposable enzyme solution sponge block 1533 protrudes from the clamping box 1532, the endoscope 3 only contacts the disposable enzyme solution sponge block 1533, thus avoiding contact with the clamping box 1532 and not causing contamination to it. Then start the first driving motor 161, the first driving motor 161 drives the driving belt 162 to rotate, and the driving belt 162 drives the clamping jaw 152 to move downward through the fixing rod 151, so as to wipe the insertion part 32 of the endoscope 3. After the wiping is completed, press down the two pressing plates 1536, and the pressing plates 1536 drive the push plate 1534 to push the disposable enzyme solution sponge block 1533 downward through the push rod 1535, so that it disengages from the clamping box 1532, thus facilitating the removal and discarding of the contaminated disposable enzyme solution sponge block 1533 without contact.

[0048] Referring to Figure 5 , the displacement mechanism 21 is arranged in the lower housing of the enzyme solution machine 2. The displacement mechanism 21 includes a second driving motor 211, a driving lead screw 212, a sliding plate 213 and a telescopic cylinder 215. The sliding plate 213 is vertically slidably connected in the lower housing of the enzyme solution machine 2. The driving lead screw 212 is axially vertically arranged and is threadedly connected to the sliding plate 213. The second driving motor 211 is fixedly connected in the housing of the enzyme solution machine 2, and its driving shaft is coaxially and fixedly connected to the top of the driving lead screw 212. A guide rod 214 is also vertically fixedly connected in the housing of the enzyme solution machine 2, and the guide rod 214 passes through the sliding plate 213. The telescopic cylinder 215 is fixedly connected to the sliding plate 213. A displacement groove 216 is vertically opened on the front surface of the housing of the enzyme solution machine 2. The telescopic shaft of the telescopic cylinder 215 extends out of the displacement groove 216 and is fixedly connected to the placement plate 22. The telescopic cylinder 215 is used to drive the placement plate 22 to move back and forth, and the second driving motor 211 is used to drive the placement plate 22 to move up and down. A clamping plate 221 is fixedly connected to the placement plate 22, and the disposable enzyme solution box 23 is clamped in the clamping plate 221 to fix it.

[0049] After the automatic wiping mechanism 15 finishes wiping the insertion portion 32 of the endoscope 3, the telescopic air cylinder 215 extends to drive the disposable enzyme solution cartridge 23 to move directly below the disposable enzyme solution sponge block 1533. Then, the clamping jaw 152 is released, and the first driving motor 161 drives the driving belt 162 to reverse, driving the clamping jaw 152 to rise a certain distance. At the same time, the second driving motor 211 drives the driving lead screw 212 to rotate, and the driving lead screw 212 drives the sliding plate 213 to move upward a certain distance, so that the distal end portion of the endoscope 3 is inserted into and immersed in the enzyme solution in the disposable enzyme solution cartridge 23. Then, the clamping jaw 152 stops moving and clamps the insertion portion 32 of the endoscope 3 again. At this time, the two disposable enzyme solution sponge blocks 1533 block the top opening of the disposable enzyme solution cartridge 23, which can effectively prevent the aerosol in the disposable enzyme solution cartridge 23 from escaping during the air supply, water supply, and aspiration operations on the endoscope 3, thereby reducing the possibility of cross-infection. To facilitate the entry of the disposable enzyme solution sponge block 1533 into the disposable enzyme solution cartridge 23, the top opening of the disposable enzyme solution cartridge 23 is enlarged and is adapted to the bottom shape when contacting the two disposable enzyme solution sponge blocks 1533, so as to guide the disposable enzyme solution sponge block 1533 and facilitate its entry. After the aspiration is completed, the pressing plate 1536 is pressed downward, so that the disposable enzyme solution sponge block 1533 can directly fall into the disposable enzyme solution cartridge 23, so that the two can be thrown into the medical waste trash can together, which is convenient for unified treatment.

[0050] The implementation principle of the bedside automatic pre-cleaning system for digestive endoscopes in the embodiment of the present application is as follows: Before the end of the diagnosis and treatment, the nursing staff first determines the height that the hanging rod 11 needs to be adjusted according to the type of the endoscope 3 used in the diagnosis and treatment. During the adjustment, the locking bolt 166 is loosened, and the height adjustment pedal 133 is stepped on downward, driving the driving rod 131 to slide downward. The driving rod 131 drives the first guide rod 132 to slide along the first guide slideway 123. The first guide rod 132 drives the connecting end of the shift lever 134 to slide downward. The shift lever 134 drives the second guide rod 137 to slide in the second guide slideway 1361. When sliding to the bottom end of the second guide slideway 1361, the connecting end of the shift lever 134 and the first guide rod 132 rotates downward, and the meshing part of the gear 1351 and the rack 1352 rotates upward, thereby pushing the rack 1352 to move upward a certain distance, that is, driving the hanging rod 11 to move upward a certain distance. The nursing staff can quickly judge the height to which it needs to be adjusted according to the indication line 139 on the hanging rod 11. After the adjustment is completed, the locking pawl 141 locks the rack 1352.

[0051] During the height adjustment process, the suspension rod 11 drives the movable pulley 163 to move towards the suspension rod 11 through the linkage rod 167. After the adjustment is completed, the driving belt 162 is tightened and the locking bolt 166 is tightened to complete the tensioning of the driving belt 162. Then the caregiver inserts two disposable enzyme solution sponges 1533 into the two clamping boxes 1532 to complete the preparation work before wiping.

[0052] After the diagnosis and treatment are completed and before the endoscope 3 is detached from the light source and the video processor, the caregiver takes over the endoscope 3, holds the operation part 31 of the endoscope 3 and mounts it on the pretreatment execution module 18. At this time, the clamping jaws 152 are in the open state and located at the top of the insertion part 32 of the endoscope 3, and the insertion part 32 of the endoscope 3 is located between the two wiping assemblies 153. Then, the caregiver swipes the endoscope 3 configuration information card at the card swiping area 171, the control module 17 is activated, the control module 17 controls the retraction of the retractable cylinder 1525, the clamping jaws 152 close, and the two disposable enzyme solution sponges 1533 contact and clamp the insertion part 32 of the endoscope 3. Then the first drive motor 161 is started, the first drive motor 161 drives the driving belt 162 to rotate, so as to drive the clamping jaws 152 to move from top to bottom, and the two disposable enzyme solution sponges 1533 wipe the insertion part 32 of the endoscope 3 from top to bottom, so that the automatic wiping of the insertion part 32 of the endoscope 3 can be completed without the caregiver's contact.

[0053] After the wiping is completed, the clamping jaws 152 open, the first drive motor 161 drives the driving belt 162 to reverse, driving the clamping jaws 152 to rise a certain distance. At this time, the enzyme solution machine 2 has filled the disposable enzyme solution box 23 with a fixed amount of enzyme solution. Then the telescopic cylinder 215 extends to drive the placement plate 22 to move to directly below the insertion part 32 of the endoscope 3, and the second drive motor 211 drives the drive screw 212 to rotate. The drive screw 212 drives the sliding plate 213 to move upward a certain distance, so that the distal end of the endoscope 3 is inserted into and immersed in the enzyme solution in the disposable enzyme solution box 23. Then the clamping jaws 152 stop moving and clamp the insertion part 32 of the endoscope 3 again. At this time, the two disposable enzyme solution sponges 1533 block the top opening of the disposable enzyme solution box 23, which can effectively prevent the aerosol in the disposable enzyme solution box 23 from escaping during the air supply, water supply and suction operations of the endoscope 3, thereby reducing the possibility of cross-infection.

[0054] The control module 17 controls the pretreatment execution module 18 to press the air supply and water supply buttons on the operation part 31 of the endoscope 3 to perform repeated air supply and water supply on the endoscope 3 for at least 10 s, and then automatically press the suction function button to suck the enzyme solution until it flows into the suction bottle to complete the air supply, water supply and suction processes of the endoscope 3.

[0055] After the aspiration process ends, the nursing staff presses down on the pressing plate 1536, so that the disposable enzyme sponge block 1533 can directly fall into the disposable enzyme solution box 23. Then, the second drive motor 211 drives the sliding plate 213 to descend until the distal end of the endoscope 3 disengages from the disposable enzyme solution box 23, and then the disposable enzyme solution box 23 is removed from the placement plate 22, so that the two can be thrown into the medical waste trash can together, which is convenient for unified treatment.

[0056] During the whole process, the nursing staff does not need to contact the insertion part 32 of the endoscope 3, and the automatic wiping, air supply / water supply and aspiration processes of the insertion part 32 of the endoscope 3 can be automatically completed, which minimizes the contact between the nursing staff and the endoscope 3 and the contaminated consumables, thus preventing the nursing staff from transferring the bacteria on the endoscope 3 to the cleaning equipment and reducing the possibility of cross-infection. At the same time, the automatic wiping is more uniform and convenient than manual wiping, improving the efficiency and comprehensiveness of wiping and cleaning.

[0057] The above are all the preferred embodiments of the present application, and the protection scope of the present application is not limited accordingly. Therefore, all equivalent changes made according to the structure, shape and principle of the present application should be covered within the protection scope of the present application.
