Description

Technical Field

[0001] The present invention belongs to the technical field of medical device cleaning, and particularly relates to an inner wall cleaning mechanism for a medical negative pressure tube. Background Art

[0002] A medical negative pressure tube (also known as a negative pressure suction tube or a negative pressure suction system tube) is a device used in the medical field to remove liquids or gases from a patient's body through negative pressure. It is commonly used in surgeries, intensive care, and emergency procedures. Its main function is to suck the patient's body fluids (such as secretions, pus, blood, etc.) or gases (such as air or gas in the chest cavity), keep the patient's respiratory tract unobstructed, or help remove other unnecessary body fluids. The inner wall of the negative pressure tube usually needs to be kept clean to avoid bacterial growth, blockage, or affecting the negative pressure effect.

[0003] Currently, when cleaning a medical negative pressure tube, it mainly relies on manual operation, using disinfectant, brushes, etc. for manual cleaning. This method is not only time-consuming but also has a high labor intensity. Especially in a medical environment where frequent cleaning is required, the efficiency is low. To ensure the cleaning effect, it usually takes a long time for thorough disinfection and rinsing, which affects the hospital's work process. Summary of the Invention

[0004] The technical problem to be solved by the present invention is to overcome the above-mentioned disadvantages of the prior art and provide an inner wall cleaning mechanism for a medical negative pressure tube.

[0005] The technical solution adopted to solve the above technical problem is: an inner wall cleaning mechanism for a medical negative pressure tube, including two fixing plates. The top of the fixing plates is fixedly connected with a handrail frame, and the bottom of the fixing plates is fixedly connected with a water storage tank. A cleaning mechanism is arranged in the middle of the two fixing plates for rotating cleaning the inner wall of the negative pressure tube. On both sides of the cleaning mechanism, a limiting suspension moving mechanism is arranged for moving the cleaning mechanism to perform linear reciprocating cleaning on the inner wall of the negative pressure tube.

[0006] Through the above technical solution, the water flow drives the fan blades to rotate, pushing the cleaning brush to rotate, thereby realizing the cleaning of the surface. Then, the hydraulic system drives the cleaning brush to perform reciprocating up and down movements to ensure more thorough cleaning. The combination of the two can cover different cleaning requirements of the inner wall of the pipeline and achieve a deep cleaning effect.

[0007] Furthermore, the limiting and suspending moving mechanism includes two skateboards arranged in an L-shaped structure. The skateboards are slidably connected through the top of the fixing plate. At the same time, the fixing plate longitudinally limits the skateboards. Two notches are formed through the skateboards. A threaded rod is rotatably connected to the bottom of the skateboard. One end of the skateboard is rotatably connected to a knob. At the same time, the connecting shaft of the knob is rotatably connected through the skateboard. The penetrating end of the connecting shaft of the knob is fixedly connected to the threaded rod. The threaded rod is threadedly connected through the fixing plate. One end of the threaded rod away from the fixing plate is threadedly connected to a connecting plate. The middle part on the side of the connecting plate away from the threaded rod is provided in a hollow state.

[0008] Through the above technical solution, the attracting and repelling movements between the electromagnet and the magnetic block drive the cleaning brush to reciprocate up and down, which can ensure that every part of the inner wall of the negative pressure pipe can be thoroughly cleaned, avoid the missed areas, can accurately control the movement track and frequency of the cleaning brush, realize efficient and continuous cleaning, and do not require manual intervention.

[0009] Furthermore, two limiting rods are fixedly connected to the surface of the bottom end of the skateboard on the side away from the knob. A connecting frame is fixedly connected to the side of the connecting plate away from the limiting rod. The middle part of the connecting frame is provided in a hollow structure. A hydraulic rod is installed in the middle part of the connecting frame. The telescopic end of the hydraulic rod is fixedly connected to a rack. The rack is located in the middle part of the connecting frame. The connecting frame laterally limits the rack. The rack is drivingly connected to a number of adjusting gears arranged linearly and equidistantly. The adjusting gears are located in the hollow of the connecting plate. At the same time, the adjusting gears are rotatably connected to the connecting plate. The rack and the adjusting gears are made of polyethylene material.

[0010] Through the above technical solution, the inner wall of the pipeline is cleaned regularly, which can effectively reduce the accumulation of dirt and bacteria, thereby reducing the impact of pollutants in the pipeline on the negative pressure system. Especially in a medical environment, it can reduce cross-infection and other health risks. At the same time, it also helps to prevent problems such as corrosion and blockage of the pipe wall caused by dirt or sediment, thereby extending the service life of the negative pressure pipe and its related equipment.

[0011] Furthermore, a number of electromagnets arranged linearly and equidistantly are rotatably connected to both sides of the connecting plate. The connecting shaft of the electromagnet is rotatably connected through the connecting plate. At the same time, the penetrating end of the connecting shaft of the electromagnet is fixedly connected to the adjusting gear. A connecting piece is rotatably connected to the middle part on the side of the electromagnet away from the connecting plate for supplying power to the electromagnet.

[0012] Furthermore, a controller is installed on the top of the handrail frame. Two power supplies fixedly installed with the handrail frame are arranged at the bottom of the controller. The power supplies are electrically connected to the connecting pieces on the outer wall of the electromagnet through wires. A water pump fixedly installed with the handrail frame is arranged between the two power supplies.

[0013] Through the above technical solution, when water flows through the inside of the negative pressure pipe, it drives the rotation of the fan blades through impact, and uses the kinetic energy of the water flow to drive the operation of the cleaning mechanism. This method utilizes the natural power of the water flow, avoiding additional energy consumption, making the cleaning process efficient and energy-saving. Then, through the rotating internal gear ring and multiple cleaning brushes on the outside, this mechanism ensures that the cleaning brushes can cover the entire inner wall of the negative pressure pipe at a uniform speed and intensity, thereby improving the cleaning effect and thoroughly removing dirt, bacteria, and scale on the inner wall.

[0014] Further, a nozzle is installed at the center of the bottom surface of the handrail frame, and the nozzle is communicated with a water pump. Both sides of the water pump are penetrated and connected with water pipes, and the other ends of the water pipes are fixedly connected through the handrail frame. At the same time, the other ends of the water pipes are located in the notch of the skateboard. The water pipes are slidably connected with the skateboard, and the water pipes are made of polyethylene material. At the same time, the end of the water pipe far from the water pump is located in the water storage tank.

[0015] Through the above technical solution, the water source is recycled during the cleaning process, reducing water resource waste. Moreover, this cleaning mechanism does not require manual intervention. The cleaning brushes are driven by the natural flow of water, realizing the automation of the cleaning process, greatly reducing the complexity and time of manual cleaning.

[0016] Further, the cleaning mechanism includes a pipe body, and a number of hollow cavities are linearly and equally spaced inside the pipe body. At the same time, a number of magnets are linearly and equally spaced on the outer wall of the pipe body. The magnets are staggered with the hollow cavities inside the pipe body. An internal gear ring is rotatably connected through the hollow cavity of the pipe body, and a number of cleaning brushes are fixedly connected to the outer wall of the internal gear ring and are arranged in a circumferential symmetry. At the same time, the cleaning brushes are of an L-shaped structure.

[0017] Through the above technical solution, since there is no mechanical contact, the components in the system are less damaged and the maintenance requirements are low. This non-contact cleaning method helps to reduce the occurrence of equipment failures, reduce maintenance costs and downtime, and reduce the wear of traditional mechanical components, improving the overall durability and reliability of the cleaning system.

[0018] Further, two driven gears arranged in a mirror image are drivingly connected to the inner diameter of the internal gear ring, and the driven gears are rotatably connected to the pipe body. A main gear is drivingly connected between the two driven gears. A connecting rod is fixedly connected through a number of the main gears, and both ends of the connecting rod are rotatably connected through the pipe body. At the same time, a fan blade is fixedly connected to the penetrating end of the connecting rod, and the fan blade is of a conical structure.

[0019] Through the above technical solution, this mechanism does not require manual intervention. Automated cleaning reduces the trouble and errors of manual cleaning, improves the working efficiency and service life of the equipment, not only improves the cleaning efficiency and comprehensiveness, but also reduces the need for manual intervention, ensuring the efficient operation, hygiene and safety of the negative pressure pipe.

[0020] The beneficial effects of the present invention are as follows:

[0021] (1) When water passes through the inside of the negative pressure pipe in the present invention, it impacts the fan blades in the cleaning mechanism, thereby driving their rotation. The connecting rod rotates simultaneously with the fan blades, driving the main gear to rotate, so that the two driven gears rotate, and then the internal gear ring rotates synchronously with the driven gears, causing several cleaning brushes on the outer wall of the internal gear ring to rotate to clean the inner wall of the negative pressure pipe. The rotational movement can effectively remove the dirt and bacteria on the inner wall of the pipe, improve the cleaning efficiency, and does not require manual intervention. Automated cleaning reduces the trouble and errors of manual cleaning, and improves the working efficiency and service life of the equipment.

[0022] (2) In the present invention, the hydraulic rod operates to drive the rack to reciprocate vertically in the connecting frame, driving the adjusting gear to rotate forward and backward. The electromagnet rotates forward and backward synchronously with the adjusting gear, causing the electromagnet and the magnetic block to form a repulsive and attractive cyclic phenomenon, thereby driving the rotating cleaning brush to reciprocate up and down, achieving a full-range cleaning of the inner wall of the negative pressure pipe. The automation of the cleaning process greatly reduces the need for manual cleaning and labor intensity, and also reduces the situation of incomplete cleaning caused by improper manual operation.

Detailed implementation manners

[0042] In order to make the objectives, technical solutions and advantages of the present invention clearer and more understandable, the present invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0043] As shown Figures 1 - 16 in the figure, a cleaning mechanism for the inner wall of a medical negative pressure tube in this embodiment includes two fixing plates 11. A handrail frame 13 is fixedly connected to the top of the fixing plate 11. A spray head 18 is installed at the center of the bottom surface of the handrail frame 13, and the spray head 18 is communicated with a water pump 15. Both sides of the water pump 15 are penetrated and connected with a water pipe 17, and the other end of the water pipe 17 is fixedly connected through the handrail frame 13. At the same time, the other end of the water pipe 17 is located in the notch 22 of the sliding plate 21. The water pipe 17 is slidably connected with the sliding plate 21, and the water pipe 17 is made of polyethylene material. At the same time, the end of the water pipe 17 away from the water pump 15 is located in the water storage tank 12. A controller 16 is installed on the top of the handrail frame 13, and two power supplies 14 fixedly installed with the handrail frame 13 are arranged at the bottom of the controller 16. A water pump 15 fixedly installed with the handrail frame 13 is arranged between the two power supplies 14. The water flow drives the fan blade 38 to rotate, and promotes the cleaning brush 37 to rotate, so as to realize the cleaning of the surface. Then, the cleaning brush 37 is driven to move up and down reciprocally through the hydraulic system to ensure more thorough cleaning. The combination of the two can cover different cleaning requirements of the inner wall of the pipeline and achieve a deep cleaning effect. The bottom end of the fixing plate 11 is fixedly connected with a water storage tank 12. When the water flow passes through the inside of the negative pressure tube, it drives the fan blade 38 to rotate by impact, and uses the kinetic energy of the water flow to drive the operation of the cleaning mechanism 3. This method utilizes the natural power of the water flow and avoids additional energy consumption, making the cleaning process efficient and energy-saving. Then, through the rotating internal gear ring 36 and multiple external cleaning brushes 37, this mechanism ensures that the cleaning brushes 37 can cover the entire inner wall of the negative pressure tube at a uniform speed and strength, thereby improving the cleaning effect and thoroughly removing dirt, bacteria and scale on the inner wall.

[0044] As shown Figures 3 - 17 in the figure, a limit suspension moving mechanism 2 is arranged on both sides of the cleaning mechanism 3 for moving the cleaning mechanism 3 to linearly reciprocate and clean the inner wall of the negative pressure tube. The limit suspension moving mechanism 2 includes two sliding plates 21 arranged in an L-shaped structure. Two limit rods 28 are fixedly connected to the bottom surface of the sliding plate 21 away from the knob 27. A connecting frame 24 is fixedly connected to the side of the connecting plate 23 away from the limit rod 28, and the middle part of the connecting frame 24 is of a hollow structure. A hydraulic rod 25 is installed in the middle of the connecting frame 24, and a rack 212 is fixedly connected to the telescopic end of the hydraulic rod 25. The rack 212 is located in the middle of the connecting frame 24, and the connecting frame 24 laterally limits the rack 212. The rack 212 is drivingly connected with a number of adjusting gears 29 arranged linearly and equidistantly, and the adjusting gears 29 are located in the hollow of the connecting plate 23. At the same time, the adjusting gears 29 are rotatably connected with the connecting plate 23.

[0045] As shown Figures 2 - 17As shown, the rack 212 and the adjusting gear 29 are made of polyethylene. The sliding plate 21 is slidably connected through the top of the fixing plate 11. At the same time, the fixing plate 11 longitudinally limits the sliding plate 21. Two notches 22 are formed through the sliding plate 21. A threaded rod 26 is rotatably connected to the bottom of the sliding plate 21. One end of the sliding plate 21 is rotatably connected to a knob 27. At the same time, the connecting shaft of the knob 27 is rotatably connected through the sliding plate 21. The penetrating end of the connecting shaft of the knob 27 is fixedly connected to the threaded rod 26. The threaded rod 26 is threadedly connected through the fixing plate 11. One end of the threaded rod 26 away from the fixing plate 11 is threadedly connected to a connecting plate 23. A number of electromagnets 210 arranged linearly at equal intervals are rotatably connected to both sides of the connecting plate 23. Waterproof treatment is carried out on the electromagnets 210 and their connecting components to reduce the influence of water splashing during the cleaning of the negative pressure pipe. The connecting shaft of the electromagnet 210 is rotatably connected through the connecting plate 23. This mechanism does not require manual intervention. Automated cleaning reduces the trouble and error of manual cleaning, improves the working efficiency and service life of the equipment, not only improves the cleaning efficiency and comprehensiveness, but also reduces the need for manual intervention, ensuring the efficient operation and hygienic safety of the negative pressure pipe. At the same time, the penetrating end of the connecting shaft of the electromagnet 210 is fixedly connected to the adjusting gear 29. A connecting piece 211 is rotatably connected to the middle of one side of the electromagnet 210 away from the connecting plate 23 for supplying power to the electromagnet 210. The middle of one side of the connecting plate 23 away from the threaded rod 26 is provided in a hollow state. The power supply 14 is electrically connected to the connecting piece 211 on the outer wall of the electromagnet 210 through a wire. When the electromagnet 210 rotates, due to the rotational connection between the electromagnet 210 and the connecting piece 211, relative rotation occurs between the connecting piece 211 and the electromagnet 210, and the connecting piece 211 and the wire do not rotate with the electromagnet 210, so that the power supply 14 can continuously transmit current to the connecting piece 211 through the wire, and then make the electromagnet 210 generate magnetic force. The water source is recycled during the cleaning process, reducing the waste of water resources. Moreover, this cleaning mechanism does not require manual intervention. The cleaning brush 37 is driven to operate by the natural flow of water, realizing the automation of the cleaning process, greatly reducing the complexity and time of manual cleaning.

[0046] As Figures 4 - 17As shown, a cleaning mechanism 3 is provided in the middle of two fixing plates 11 for rotatably cleaning the inner wall of the negative pressure pipe. The cleaning mechanism 3 includes a pipe body 31, and a number of hollow cavities are provided inside the pipe body 31 in a linearly equally spaced manner. At the same time, a number of magnets 32 are installed on the outer wall of the pipe body 31 in a linearly equally spaced manner. The attraction and repulsion movement between the electromagnet 210 and the magnets 32 drives the cleaning brush 37 to reciprocate up and down, which can ensure that every part of the inner wall of the negative pressure pipe can be thoroughly cleaned, avoiding missed areas, and can accurately control the movement trajectory and frequency of the cleaning brush 37 to achieve efficient and continuous cleaning without manual intervention. When the magnetism of the magnet 32 disappears during daily use, it can be replaced. The magnets 32 and the hollow cavities inside the pipe body 31 are arranged in a staggered manner. An internal gear ring 36 is rotatably connected through the hollow cavity of the pipe body 31. The inner diameter of the internal gear ring 36 is drivingly connected with two mirror-image driven gears 35. Since there is no mechanical contact, the components in the system are less damaged and the maintenance requirements are low. This non-contact cleaning method helps to reduce the occurrence of equipment failures, reduce the maintenance cost and downtime. Moreover, it reduces the wear of traditional mechanical components, improving the overall durability and reliability of the cleaning system. The driven gear 35 is rotatably connected to the pipe body 31. A main gear 34 is drivingly connected between the two driven gears 35. A connecting rod 33 is fixedly connected through a number of main gears 34. The two ends of the connecting rod 33 are rotatably connected through the pipe body 31. At the same time, a fan blade 38 is fixedly connected to the penetrating end of the connecting rod 33, and the fan blade 38 is arranged in a conical structure. An outer wall of the internal gear ring 36 is fixedly connected with a number of cleaning brushes 37 arranged in a circumferentially symmetric manner. At the same time, the cleaning brush 37 is arranged in an L-shaped structure. The inner wall of the pipe is regularly cleaned, which can effectively reduce the accumulation of dirt and bacteria, thereby reducing the impact of pollutants in the pipe on the negative pressure system. Especially in a medical environment, it reduces cross-infection and other health risks. At the same time, it also helps to prevent problems such as corrosion and blockage of the pipe wall caused by dirt or sediment, thereby extending the service life of the negative pressure pipe and its related equipment.

[0047] The working principle of this embodiment is as follows. Before cleaning, after filling the water storage tank 12 with water, place the negative pressure pipe between the two sliding plates 21, and then rotate the knob 27 to drive the threaded rod 26 to rotate, so that the sliding plates 21 and the components fixedly connected to the bottom thereof move in the direction of the negative pressure pipe at the same time. Furthermore, the limiting rod 28 clamps and limits the negative pressure pipe, causing the negative pressure pipe to be in a stretched vertical state, and leaving a certain gap between the nozzle of the negative pressure pipe and the nozzle 18. Then, the staff can operate the controller 16 to prompt the power supply 14 to operate. Under the action of the wire, the current is transmitted to the connector 211, and the electromagnet 210 receives the current and generates a magnetic force. At this time, the electromagnet 210 is in a horizontal state.

[0048] Then, the cleaning mechanism 3 is placed into the negative pressure pipe. Under the repulsive force of the electromagnet 210 and the magnetic block 32 on the outer wall of the pipe body 31, the overall assembly of the cleaning mechanism 3 is in a suspended state. Then, the water pump 15 operates to suck up the water in the water storage tank 12 through the water pipe 17 and spray it out from the nozzle 18. Under the action of gravity, the water falls into the interior of the negative pressure pipe and then returns to the water storage tank 12, realizing the recycling of water resources and reducing waste.

[0049] When the water passes through the interior of the negative pressure pipe, it impacts the fan blades 38 in the cleaning mechanism 3, thereby driving their rotation. The connecting rod 33 rotates simultaneously with the fan blades 38, driving the main gear 34 to rotate, so that the two driven gears 35 rotate, and then the internal gear ring 36 rotates synchronously with the driven gears 35, causing several cleaning brushes 37 on the outer wall of the internal gear ring 36 to rotate to clean the inner wall of the negative pressure pipe.

[0050] Then, the hydraulic rod 25 operates to drive the rack 212 to reciprocate in the vertical direction of the connecting frame 24, driving the adjusting gear 29 to rotate forward and backward. The electromagnet 210 rotates forward and backward synchronously with the adjusting gear 29, causing the electromagnet 210 and the magnetic block 32 to form a reciprocating phenomenon of repulsion and attraction, thereby driving the rotating cleaning brush 37 to move up and down reciprocally to achieve a full - range cleaning of the inner wall of the negative pressure pipe.

[0051] The above - mentioned is only the preferred embodiment of the present invention and is not used to limit the protection scope of the present invention.
