Description

Technical Field

[0001] This invention relates to the field of gastroscopy cleaning technology, and more particularly to a gastroscopy cleaning device for use in the Department of Gastroenterology. Background Technology

[0002] In gastroenterology, the endoscope, a slender, flexible, and complex tubular precision instrument with intricate internal cavities, requires meticulous cleaning and disinfection after each use. Its unique tubular structure, along with its complex folds and crevices, makes it highly susceptible to the accumulation of bodily fluids, mucus, and biofilms. Inadequate cleaning can create a breeding ground for pathogens, directly impacting medical safety and patient health.

[0003] Traditional gastroscopy cleaning methods in the present technology mostly rely on manual operation, including multiple steps such as preliminary rinsing, enzyme washing, brushing, rinsing, soaking in disinfectant solution, and final drying. This process is not only tedious and time-consuming, but the cleaning quality is also highly susceptible to fluctuations due to differences in the operator's skill level and sense of responsibility. It has inherent drawbacks such as incomplete cleaning, difficulty in reaching dead corners, and a high risk of cross-infection. Although some gastroscopy cleaning equipment exists, such as those using soaking tanks or single spray cleaning designs, they often fail to effectively clean the complex structures such as bends and crevices on the outer wall of the endoscope tube, especially with poor removal of stubborn biofilms. In addition, some equipment has a fixed cleaning space and cannot adapt to continuous and batch cleaning. The large volume of cleaning demands, coupled with the disconnect between cleaning and drying processes, leads to inefficiency. For example, while Chinese patent document CN118614852A, a gastroenterology endoscope cleaner, mentions the need to improve cleaning speed, its solution still has room for improvement in terms of thoroughness and automation. Another type of technical solution, such as the cleaning and disinfection equipment in Chinese patent document CN115192743B, attempts to integrate functions such as spraying and drying, but in practical applications, it may face problems such as complex structure, unstable fixation of the endoscope leading to uneven cleaning, or poor connection between different cleaning processes. Therefore, this application discloses a gastroenterology endoscope cleaning device. Summary of the Invention

[0004] In view of this, the purpose of this invention is to provide a gastroscopy cleaning device for the Department of Gastroenterology, so as to solve the problems of traditional gastroscopy cleaning relying on manual operation or simple equipment, which makes it difficult to thoroughly clean the curved tubes and crevices, and the cleaning quality is prone to fluctuation, with low efficiency and high risk of cross-infection.

[0005] To achieve the above objectives, the present invention provides a gastroscopy cleaning device for gastroenterology, comprising: a work frame, a conveyor belt disposed on one upper side of the work frame, a first drive motor disposed on one bottom side of the work frame, the output end of the first drive motor being connected to one of the rotating rollers of the conveyor belt via chain drive or belt drive, and a collection platform disposed on the other upper side of the work frame. Several rows of placement components are respectively arranged on the conveyor belt, and the placement components are used to place the endoscope body and limit its position. A cleaning assembly is disposed on one side of the middle part of the work stand, and the cleaning assembly is used to clean the endoscope body; A drying mechanism is located on the other side of the middle part of the work frame. The drying mechanism is used to dry the gastroscope body after cleaning.

[0006] Preferably, the cleaning assembly includes a cleaning box fixedly installed on one side of the middle of the work frame, and fixed blocks on both sides of the top surface of the work frame. A plurality of auxiliary rollers and cleaning roller brushes are rotatably installed between the two fixed blocks and inside the work frame. The auxiliary rollers and cleaning roller brushes located inside the work frame are arranged in the middle of the upper and lower layers of the conveyor belt, and the auxiliary rollers and cleaning roller brushes between the two fixed blocks are arranged above the conveyor belt. The auxiliary rollers and cleaning roller brushes are arranged alternately. The plurality of auxiliary rollers and cleaning roller brushes are all connected by gear transmission. A second drive motor is also provided on one side of the bottom of the work frame. The output end of the second drive motor is connected to one of the auxiliary rollers by chain transmission or belt transmission.

[0007] Preferably, the cleaning tank is provided with rinsing pipes on both the upper and lower sides, the rinsing pipes are connected to an external water pump, and the two rinsing pipes are respectively arranged above and below the conveyor belt.

[0008] Preferably, the conveyor belt has several cleaning grooves running through it, which are used to facilitate cleaning by the cleaning components.

[0009] Preferably, the placement assembly includes a fixed plate fixedly installed on the conveyor belt, a positioning post is provided in the middle of the top surface of the fixed plate, a fixed plate is provided on the top of the positioning post, the fixed plate has three sliding grooves, three clamping plates are slidably installed on the top surface of the fixed plate, the three clamping plates are distributed in a circumferential shape, the bottom of the clamping plates are slidably installed inside the sliding grooves, and clamping blocks are provided on the inner side of each clamping plate.

[0010] Preferably, a sliding disc is movably sleeved in the middle of the positioning post, and a return spring is provided at the bottom of the sliding disc. The other end of the return spring is fixedly connected to the top surface of the fixing plate. Three connecting rods are rotatably installed on the outer periphery of the sliding disc, and the other side of the three connecting rods is rotatably connected to the bottom of the three clamping plates respectively. When the sliding disc is pressed down, the connecting rods drive the three clamping plates to slide inside the slide groove and move closer to each other.

[0011] Preferably, the three clamps are spaced apart for surrounding the endoscope body, and the opposing surfaces of the three clamps are convex to compress and limit the endoscope body.

[0012] Preferably, the fixed plate has several large through slots for use with the cleaning assembly for cleaning.

[0013] Preferably, each row of the placement components is provided with four, and a connecting rod is provided between the sliding discs of every two placement components in each row. A steel frame is provided above each fixing block, and two extension rods are provided on the inner side of each steel frame. The two extension rods on the two steel frames are provided with a trigger rod. The two trigger rods are located above the conveyor belt. The bottom of the trigger rod away from the collection table is inclined. The trigger rod is used to press the connecting rod.

[0014] Preferably, when the conveyor belt passes the cleaning assembly, the trigger rod presses the connecting rod, causing the sliding disc to move downward, thereby causing the three clamping plates to move closer to each other.

[0015] The beneficial effects of this invention are: This endoscope cleaning device for gastroenterology uses a placement component with a trigger rod and connecting rod. A conveyor belt drives the placement component to move at a constant speed. When the component enters the cleaning area, the trigger rod, fixed to the steel frame, smoothly presses down on the connecting rod with its inclined bottom surface. This forces the sliding plate to overcome the return spring force and move downward. Through three connecting rods, three clamping plates are simultaneously driven to precisely retract towards the center along the sliding groove of the fixed plate, forming a three-point encircling clamping of the endoscope body. This achieves full automation of the "movement-trigger-locking" process, ensuring that each endoscope is quickly and accurately positioned at the center of the rinsing force field before entering the high-pressure rinsing and roller brush cleaning. Furthermore, the convex clamping blocks form point contact with the endoscope surface, providing sufficient frictional resistance while avoiding the risk of scratches. The three-point spacing layout ensures clamping stability and provides ample channels for the cleaning fluid in the vertical direction, eliminating cleaning dead corners on the endoscope surface and significantly improving cleaning uniformity and reliability.

[0016] Equipped with a cleaning component, the cleaning tank features bidirectional flushing pipes with opposing vertical jets. Combined with a specially designed cleaning trough on the conveyor belt, this forms a penetrating water curtain that pre-softens and washes away large pieces of dirt. Next, the endoscope enters a cleaning area composed of alternating auxiliary rollers and cleaning brushes. A second drive motor, via gear transmission, drives all the brushes to rotate synchronously. The auxiliary rollers stabilize the endoscope's posture to prevent swaying, while the cleaning brushes provide a comprehensive scrubbing of the endoscope's surface. This alternating arrangement allows the endoscope to withstand multi-angle circumferential friction during axial movement, effectively cleaning complex geometric areas such as bends and crevices. This combined approach of "hydraulic impact pretreatment + mechanical brushing deep cleaning," along with multi-dimensional vertical and horizontal forces, significantly improves the dirt removal rate.

[0017] The system integrates functional modules such as conveyor belt transport, automatic clamping of placement components, composite cleaning of washing components, efficient dehydration by the drying mechanism, and final collection on the collection platform into a continuous linear workflow. The clamping mechanism automatically locks in the cleaning area and automatically resets after removal, and its timing is matched with the rinsing, brushing, and drying actions, eliminating efficiency bottlenecks and cross-infection risks caused by manual intervention. The entire system forms a closed processing environment, significantly improving the efficiency of gastroscopy endoscope cleaning and disinfection. Attached Figure Description

[0021] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to specific embodiments.

[0022] It should be noted that, unless otherwise defined, the technical or scientific terms used in this invention should have the ordinary meaning understood by one of ordinary skill in the art to which this invention pertains. The terms "first," "second," and similar terms used in this invention do not indicate any order, quantity, or importance, but are merely used to distinguish different components. Terms such as "comprising" or "including" mean that the element or object preceding the word encompasses the elements or objects listed following the word and their equivalents, without excluding other elements or objects. Terms such as "connected" or "linked" are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. Terms such as "upper," "lower," "left," and "right" are used only to indicate relative positional relationships; when the absolute position of the described object changes, the relative positional relationship may also change accordingly.

[0023] like Figures 1 to 8 As shown, the endoscope cleaning device for gastroenterology includes a work frame 1, a conveyor belt 2 on one side of the upper part of the work frame 1, a first drive motor 3 on one side of the bottom part of the work frame 1, the output end of the first drive motor 3 being connected to one of the rotating rollers of the conveyor belt 2 via chain drive or belt drive, a collection platform 4 on the other side of the upper part of the work frame 1; several rows of placement components, each arranged on the conveyor belt 2, used to place and limit the endoscope body; a cleaning component, located on one side of the middle part of the work frame 1, used to clean the endoscope body; and a drying mechanism 26, located on the other side of the middle part of the work frame 1, used to dry the cleaned endoscope body. The entire machine forms a linear operational chain of "automatic conveying → sequential placement → fixed-point cleaning → fixed-point drying → automatic collection". When the gastroscope moves along the conveyor belt 2 into the central cleaning component area, the cleaning component can perform deep cleaning on the outer wall of the gastroscope and the gaps in the curved sections, ensuring that each gastroscope receives a consistent and thorough surface cleaning effect. Subsequently, the gastroscope continues to move along the conveyor belt 2 into the drying mechanism 26 area on the other side of the work rack 1. The drying mechanism 26 uses directional hot air, circulating air ducts, or local pressure drying to quickly dehydrate the outer surface of the gastroscope, which still has water droplets attached after cleaning. Through a stable conveying speed, each gastroscope receives a consistent drying time and heating conditions, thereby improving the overall drying effect and reducing the risk of bacterial growth. Finally, the dried gastroscope is smoothly conveyed to the collection table 4, where staff can directly use it or perform subsequent sterilization. This integrated serial automatic process of "cleaning-drying-collection" not only reduces manual intervention and improves efficiency, but also significantly reduces the risk of infection, improves the standardization of disinfection treatment, and achieves continuous, efficient, and safe high-frequency cleaning tasks in medical settings.

[0024] like Figures 1 to 4 As shown, the cleaning assembly includes a cleaning box 5 fixedly installed on one side of the middle of the work frame 1, and fixed blocks 7 on both sides of the top surface of the work frame 1. Several auxiliary rollers 8 and cleaning roller brushes 9 are rotatably installed between the two fixed blocks 7 and inside the work frame 1. The auxiliary rollers 8 and cleaning roller brushes 9 located inside the work frame 1 are arranged in the middle of the upper and lower layers of the conveyor belt 2. The auxiliary rollers 8 and cleaning roller brushes 9 between the two fixed blocks 7 are arranged above the conveyor belt 2. The auxiliary rollers 8 and cleaning roller brushes 9 are arranged in an alternating manner. Several auxiliary rollers 8 and cleaning roller brushes 9 are all connected by gear transmission. A second drive motor 10 is also provided on one side of the bottom of the work frame 1. The output end of the second drive motor 10 is connected to one of the auxiliary rollers 8 by chain transmission or belt transmission. Rinsing pipes 6 are provided on both the upper and lower sides of the cleaning box 5. The rinsing pipes 6 are connected to an external water pump. The two rinsing pipes 6 are respectively arranged above and below the conveyor belt 2. Several cleaning grooves 11 are opened through the conveyor belt 2. The cleaning grooves 11 are used to facilitate cleaning by the cleaning assembly. The cleaning tank 5 provides a closed working space to prevent water splashing. The rinsing pipes 6, located on the upper and lower sides of the conveyor belt 2, continuously spray high-pressure water onto the outer wall of the endoscope under the action of a water pump. This softens the dirt on the endoscope surface before it enters the roller brush area. Simultaneously, the arrangement of the upper and lower sprays allows water to cover the endoscope from two directions, eliminating cleaning dead zones. The cleaning trough 11 on the conveyor belt 2 allows the sprayed water to directly penetrate the conveyor belt 2 and fall onto the lower side of the endoscope. Combined with the upward spray from the rinsing pipes 6 below, this forms an "upper and lower counter-rinsing water curtain," which not only enhances rinsing ability but also immediately removes dirt brushed off during the washing process from the contact surface, preventing re-adhesion. As the endoscope continues to move forward, it enters the area where the auxiliary rollers 8 and cleaning roller brushes 9 intersect. One auxiliary roller 8, driven by the second drive motor 10, drives all the auxiliary rollers 8 and cleaning roller brushes 9 through gear linkage. Synchronous rotation ensures continuous, enveloping contact between the roller brushes and the outer wall of the endoscope. The staggered arrangement allows the endoscope to be brushed in multiple directions—front-to-back, left-to-right, and at local angles—enhancing the cleaning of crevices and complex curved surfaces. The auxiliary roller 8 prevents the endoscope from swaying due to brush force deviation, ensuring stable and uniform brushing force. The upper and lower roller brush structure keeps the endoscope held and covered by the brushes as it passes through, providing not only spray impact but also mechanical friction, creating a combined "water force + brush force" cleaning effect. This ensures cleanliness while reducing manual brushing. Finally, all spray water and wastewater are quickly discharged through the cleaning tank 11 to the bottom of the cleaning box 5 for centralized treatment, maintaining a clean and non-fouling cleaning environment. The entire process forms a stable and continuous automated deep cleaning chain, significantly improving cleaning efficiency, stability, and hygiene safety.

[0025] like Figures 4 to 8 As shown, the placement assembly includes a fixed plate 15 fixedly mounted on the conveyor belt 2. A positioning post 16 is provided in the center of the top surface of the fixed plate 15. A fixed plate 17 is provided on the top of the positioning post 16. Three sliding grooves 18 are provided on the fixed plate 17. Three clamping plates 22 are slidably mounted on the top surface of the fixed plate 17. The three clamping plates 22 are distributed in a circumferential shape. The bottom of the clamping plates 22 is slidably mounted inside the sliding grooves 18. Clamping blocks 24 are provided on the inner side of each clamping plate 22. A sliding plate 20 is movably sleeved in the center of the positioning post 16. A return spring 21 is provided at the bottom of the sliding plate 20. The other end of 21 is fixedly connected to the top surface of the fixed plate 15. Three connecting rods 23 are rotatably installed on the outer periphery of the sliding disk 20. The other side of the three connecting rods 23 is rotatably connected to the bottom of the three clamping plates 22 respectively. When the sliding disk 20 is pressed down, the connecting rods 23 drive the three clamping plates 22 to slide inside the sliding groove 18 and move closer to each other. The three clamping plates 22 are spaced apart and used to wrap around the endoscope body. The opposite surfaces of the three clamping blocks 24 are all convex and used to squeeze and limit the endoscope body. Several large through grooves 19 are opened on the fixed disk 17 for cleaning in conjunction with the cleaning component. The fixing plate 17 has three circumferentially distributed sliding grooves 18, allowing the three clamping plates 22 to move symmetrically in the radial direction. This symmetrical structure ensures uniform force distribution when the endoscope is clamped, preventing bias pressure that could cause bending or damage. The sliding plate 20, sleeved on the outer side of the positioning post 16, is kept in its initial open state by a return spring 21, facilitating the operator to directly place the endoscope into the center position and improving loading convenience. When the sliding plate 20 is pressed down, the three connecting rods 23 are simultaneously pulled, causing the three clamping plates 22 to converge towards the center along the sliding grooves 18, forming an automatic "encircling clamp." This quickly and stably clamps the endoscope body, and the three clamping plates 22 are spaced apart, providing three-point clamping to the endoscope. The corner limiter prevents the endoscope from rolling, jumping, or shifting during the movement of the conveyor belt 2. The clamping blocks 24 on the inner side of the clamping plate 22 have a convex structure, which achieves point contact and increases friction. While ensuring the clamping effect, it avoids large-area contact that may cause scratches and protects the surface material of the endoscope. While the clamping plate 22 clamps, the clamping blocks 24 exert uniform pressure on the endoscope, ensuring that the endoscope maintains a stable posture in the roller brush area of ​​the cleaning component. This allows the water flow and roller brush to always act in the correct position, improving the thoroughness of cleaning. Several large through slots 19 on the fixed plate 17 allow the water sprayed from the upper and lower parts and the wastewater generated by the roller brush to pass through freely without accumulating on the clamp, making the cleaning process more thorough and avoiding cleaning blind spots.

[0026] like Figure 3 , Figure 5 As shown, each row of placement components is set with four components. A connecting rod 25 is provided between every two sliding discs 20 in each row. A steel frame 12 is provided above each fixed block 7. Two extension rods 13 are provided on the inner side of each steel frame 12. The two extension rods 13 on the two steel frames 12 are provided with a trigger rod 14. The two trigger rods 14 are located above the conveyor belt 2. The bottom of the trigger rod 14 away from the collection table 4 is inclined. The trigger rod 14 is used to press the connecting rod 25. When the conveyor belt 2 passes the cleaning component, the trigger rod 14 presses the connecting rod 25, causing the sliding disc 20 to move downward, thereby causing the three clamping plates 22 to move closer to each other. The bottom of the trigger rod 14 is tilted so that it can smoothly contact the connecting rod 25 and apply pressure when the conveyor belt 2 moves over it, causing the sliding plate 20 to be pressed downward. The follower rod 23 drives the three clamping plates 22 to converge towards the center along the slide groove 18. The clamping plates 22 move closer together evenly during the sliding process, achieving three-point symmetrical clamping of the endoscope. The advantage of this design is that it can achieve automatic clamping during continuous transport without manual intervention, while ensuring that each endoscope is accurately positioned and firmly fixed before entering the cleaning area, preventing displacement or tilting caused by transport vibration, and enhancing the cleaning assembly. The system improves efficiency and automatically triggers the action without requiring an additional power source, achieving mechanized and highly reliable automatic clamping. The entire process forms a continuous automatic action chain: "conveyor belt 2 drives trigger rod 14 - trigger rod 14 presses connecting rod 25 - sliding plate 20 presses down - connecting rod 23 drives clamping plate 22 to close - clamping block 24 clamps the endoscope." This ensures that each endoscope is in the optimal force and positioning state when entering the cleaning component, thereby improving the uniformity of subsequent cleaning and overall efficiency. Subsequently, when the endoscope is conveyed out of the cleaning component area, the limit will be released simultaneously.
