Description

Technical Field

[0001] The present invention relates to the technical field of medical equipment cleaning, in particular to an equipment cleaning tank for a disinfection supply center. Background Art

[0002] The Center for Sterilization and Supply (CSSD) is responsible for the cleaning, disinfection, sterilization, and sterile supply of all reusable medical instruments, instruments, and supplies within the hospital. As a fundamental and critical step in this process, cleaning has profound implications and specific industry contexts. The following explains this from multiple perspectives:

[0003] 1. Hazards of contaminants: Organic or inorganic contaminants such as blood, body fluids, secretions, mucus, protein, and fat may adhere to the surface of used diagnostic and treatment instruments. If these contaminants are not thoroughly removed, they will form biofilms, hindering the effective contact between subsequent disinfection and sterilization agents and microorganisms, leading to disinfection and sterilization failure.

[0004] 2. Risk of microbial transmission: Contaminants may carry bacteria (such as Staphylococcus aureus, Escherichia coli), viruses (such as hepatitis B virus, new coronavirus), fungi and other pathogens. If the equipment is not thoroughly cleaned, cross infection may occur through diagnosis and treatment operations.

[0005] Some sterilization supply center instrument cleaning tanks on the market (such as the SZ-QXC200) are mostly fixed in height, making it difficult to adjust to the heights of different staff members and operational requirements. This can lead to fatigue among staff members during long hours of operation, reducing work efficiency.

[0006] Therefore, the present invention provides an instrument cleaning tank for a sterilization supply center to solve the above problems. Summary of the Invention

[0007] In order to solve the above problems, the present invention provides an instrument cleaning tank for a disinfection supply center. Through the cooperation of a lifting component and a heating component, it effectively solves the problems of fixed height and unadjustable water temperature in existing cleaning tanks, thereby improving the professionalism and practicality of instrument cleaning in disinfection supply centers.

[0008] In order to achieve the above-mentioned purpose, the technical solution of the present invention is as follows: an instrument cleaning tank for a disinfection supply center includes a cabinet and a controller, the controller is installed on the surface of the cabinet, a faucet is installed on the top of the cabinet, an external cleaning tank that slides with the cabinet is installed on the top of the cabinet, an inner cleaning tank is installed inside the outer cleaning tank, and a heating component for heating the liquid in the inner cleaning tank is provided between the outer cleaning tank and the inner cleaning tank; a lifting component for adjusting the height of the outer cleaning tank is provided in the cabinet; a recovery component for recovering the cleaning liquid is provided at the bottom of the inner cleaning tank; the heating component and the lifting component are both electrically connected to the controller.

[0009] Basic Solution Principle: During operation, workers activate the lifting assembly via a controller. This assembly adjusts the height of the external cleaning trough, which slides against the cabinet, to accommodate different worker heights and operating requirements. This optimized operating height effectively reduces fatigue from prolonged operation, thereby improving work efficiency.

[0010] For cleaning of medical devices that require specific water temperature, the staff also sets the appropriate temperature parameters on the controller. The controller transmits the signal to the heating component, and the heating component starts working to heat the liquid between the outer cleaning tank and the inner cleaning tank. Through heat transfer, the cleaning liquid in the inner cleaning tank reaches the set temperature, meeting the cleaning needs of medical devices with special temperature requirements, ensuring the cleaning effect, and avoiding problems such as incomplete cleaning due to inappropriate temperature.

[0011] The recovery assembly at the bottom of the inner cleaning tank can promptly recover the cleaning fluid in the tank after cleaning is completed. This allows for subsequent processing, recycling resources and reducing water waste. It also facilitates cleaning and maintenance of the tank. Throughout the entire process, the controller serves as the core control unit, precisely controlling the lifting and heating components to achieve tank height adjustment and water temperature control, making the tank more professional and practical in actual use.

[0012] The above scheme has the following beneficial effects: 1. The height-adjustable design significantly improves operational comfort and work efficiency. Traditional fixed-height cleaning tanks can easily cause fatigue among workers of different heights due to improper postures, which in turn affects the cleaning quality and efficiency. The present invention drives the lifting assembly through a controller to achieve flexible adjustment of the height of the external cleaning tank. Workers can adjust to the optimal operating height according to their own needs, effectively alleviating the physical burden caused by long-term bending, raising hands and other bad postures, reducing muscle strain and fatigue, improving the operational comfort of workers, and enabling them to maintain a good state at work, improving the accuracy and speed of cleaning operations, thereby greatly improving the overall work efficiency of the disinfection supply center and ensuring that medical equipment cleaning work is carried out efficiently and orderly.

[0013] 2. Intelligent water temperature control and cleaning fluid recovery functions ensure cleaning effectiveness and promote resource conservation. For some medical devices that are sensitive to water temperature, the heating component, under the control of the controller, can accurately adjust the water temperature in the internal cleaning tank, ensuring that the cleaning fluid is always maintained at the appropriate temperature to meet the cleaning requirements of different instruments. This avoids contaminant residue or instrument damage caused by improper water temperature, ensuring cleaning effectiveness while improving the success rate of disinfection and sterilization and reducing the risk of cross-infection.

[0014] Furthermore, the lifting assembly includes a pair of ball screws and a pair of stabilizing rods, and the threaded seats of the ball screws are respectively installed at a set of diagonal positions at the bottom end of the external cleaning tank; the stabilizing rods are slidably fitted with stabilizing seats, and the two stabilizing seats are respectively installed at another set of diagonal positions at the bottom end of the external cleaning tank; both ends of the stabilizing rods are fixedly connected to the inner wall of the cabinet; the top ends of the ball screws are fixedly connected to the top wall of the cabinet, and the bottom ends of the ball screws are engaged with transmission components, which are installed at the bottom of the cabinet, and the transmission components are electrically connected to the controller.

[0015] Beneficial Effects: A pair of ball screws and a pair of stabilizer bars provide stable and precise support and transmission for the raising and lowering of the external cleaning tank. The ball screw's threaded seat is installed at a diagonal angle at the bottom of the external cleaning tank. When the transmission assembly rotates the screw, the seat converts the rotational motion into linear motion, driving the external cleaning tank to rise and fall smoothly. Simultaneously, another set of diagonal stabilizer bars slide in conjunction with the seat, effectively limiting the shaking and deviation of the external cleaning tank during the raising and lowering process, enhancing the stability of the overall structure.

[0016] Furthermore, the heating component includes a temperature sensor and several heating wires, the heating wire ring is arranged in the gap between the outer cleaning tank and the inner cleaning tank; the temperature sensor is arranged at the bottom of the inner cleaning tank; the temperature sensor and the heating wires are both electrically connected to the controller.

[0017] Beneficial Effects: The heating wire ring, located in the gap between the outer and inner cleaning tanks, evenly heats the liquid in the inner tank, ensuring uniform water temperature distribution and preventing local overheating or overcooling from affecting the cleaning effect. A temperature sensor at the bottom of the inner tank monitors the water temperature in real time and feeds this data back to the controller. The controller intelligently adjusts the power of the heating wire based on preset temperature parameters to achieve precise control of the water temperature. This closed-loop control method ensures that the water temperature remains within the set range, not only meeting the cleaning requirements of various temperature-sensitive medical devices, but also effectively avoiding energy waste, improving energy efficiency, and ensuring cleaning results while reducing operating costs.

[0018] Furthermore, the recovery component includes a recovery pipe, one end of which passes through the outer cleaning tank and extends into the inner cleaning tank. A filter screen and a mesh plug are built into the recovery pipe near one end of the inner cleaning tank; the other end of the recovery pipe is connected to a recovery box.

[0019] Beneficial effects: The design of the recovery tube, filter, mesh plug and recovery box enables efficient recovery and preliminary filtration of the cleaning fluid. One end of the recovery tube extends into the inner cleaning tank to facilitate the extraction of the cleaning fluid. The built-in filter can intercept larger impurities in the cleaning fluid, such as debris and dirt particles that fall off the instrument, to prevent these impurities from entering the recovery box and causing blockage or pollution, thereby ensuring the smooth operation of the recovery system. The mesh plug can close the entrance of the recovery tube when the recovery function is not in use to prevent leakage of cleaning fluid or entry of debris. The recovery box is used to centrally store the recovered cleaning fluid for subsequent unified processing, to achieve the recycling of water resources, and to reduce waste. It also simplifies the cleaning fluid recovery process and facilitates operation and management by staff.

[0020] Furthermore, an isolation boss and a water collecting tank are provided at the top of the cabinet along the circumference of the outer cleaning tank from the inside to the outside; a top cover is fixedly connected to the top of the outer cleaning tank, and an isolation groove is opened at the bottom of the top cover along the circumference of the outer cleaning tank, and the isolation groove corresponds to the isolation boss.

[0021] Benefits: The isolation boss and sump on the cabinet top, combined with the isolation groove on the external cleaning tank cover, form an effective spill prevention and protection system. The isolation boss and groove work together to block spilled cleaning fluid during the cleaning process, preventing it from splattering and maintaining a clean work environment. The sump collects spilled cleaning fluid, preventing it from flowing onto the outside of the cabinet or onto the floor, reducing cleaning workload and the risk of slips.

[0022] Furthermore, the isolation boss is composed of an air bag layer and a fixed seat from top to bottom. The air bag layer is connected to a number of air supply channels along the circumference of the fixed seat. The air supply channels are all connected to auxiliary cleaning pipes fixed on the top wall of the cabinet. The auxiliary cleaning pipes are connected to the recovery pipe at one end away from the isolation boss; the water collection tank is evenly distributed with a number of water suction pipes along the inner bottom wall and the circumference of the water collection tank, and the water suction pipes are all connected to the air supply channels; the diameter of the water suction pipes is smaller than that of the air supply channels.

[0023] Beneficial Effects: The design of the isolation boss's airbag layer, air delivery channel, auxiliary cleaning pipe, and water suction pipe enables intelligent auxiliary cleaning of the cleaning tank. When the top cover descends and resets, the isolation groove and isolation boss overlap to squeeze the airbag layer. The gas flow generated by the pressure on the airbag layer, combined with the Bernoulli principle, automatically recovers residual liquid in the sump. This allows for rapid removal of accumulated water from the sump without manual intervention, significantly improving cleaning efficiency, saving labor costs and cleaning time, and allowing the tank to be put back into use sooner.

[0024] Furthermore, the cabinet surface is provided with a plurality of placement slots for placing cleaning bottles, and the top cover surface of the outer cleaning slot is provided with a plurality of pump heads corresponding to the placement slots, and the bottom ends of the pump heads are connected to infusion tubes for placing in the cleaning bottles.

[0025] Benefits: The cabinet's surface placement slots, pump head, and infusion tube design on the top cover provide convenient cleaning fluid addition. Workers can place different types of cleaning fluid in the cleaning bottles in the placement slots. When needed, simply operate the pump head to transfer the cleaning fluid from the corresponding cleaning bottle to the cleaning tank through the infusion tube, eliminating the need for frequent manual pouring. This simple and quick operation saves time and manpower.

[0026] Furthermore, the middle portion of the recovery pipe is configured as a corrugated structure.

[0027] Beneficial Effects: The corrugated structure in the middle of the recovery tube significantly enhances its flexibility and resistance to deformation. As the cleaning tank is raised or lowered, the relative position between the outer and inner cleaning tanks changes. The corrugated structure freely expands and contracts, effectively buffering the stress generated by height adjustment, preventing the recovery tube from rupturing due to excessive bending or stretching, and extending its service life. Furthermore, the corrugated structure increases the internal surface area of ​​the recovery tube, creating turbulent flow during liquid flow, reducing the likelihood of impurities adhering to the tube walls and the risk of clogging. This ensures unimpeded recovery of the cleaning fluid and enhances the stability and reliability of the recovery system.

[0028] Furthermore, a heat-insulating ring is sleeved on the surface of the recovery pipe; the heat-insulating ring is located between the outer cleaning tank and the inner cleaning tank.

[0029] Beneficial Effects: The heat-insulating ring effectively blocks heat transfer between the outer and inner cleaning tanks. When the heating wire is operating, the heat-insulating ring reduces the effect of the heating wire on the temperature inside the recovery pipe, preventing the cleaning fluid inside the recovery pipe from heating up.

[0030] Furthermore, scale lines are engraved on the inner wall of the inner cleaning tank.

[0031] Benefits: The scale lines on the inner wall of the inner cleaning tank provide an accurate reference for the liquid level during cleaning. When adding cleaning fluid or controlling the amount of water used, the scale lines provide an intuitive understanding of the liquid volume, ensuring that the cleaning fluid concentration meets the requirements, and avoiding overflows caused by excessively high liquid levels or impacts on cleaning results due to insufficient liquid levels.

[0032] Additional aspects and advantages of the present invention will be set forth in part in the description which follows and, in part, will be obvious from the description which follows, or may be learned by practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0044] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0045] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0046] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0047] The following is further described in detail through specific implementation methods:

[0048] Example 1:

[0049] Based on the existing technology of instrument cleaning tanks for disinfection supply centers (such as the SZ-QXC200 model, most of these cleaning tanks are customized with fixed sizes). In actual use, the staff of the disinfection supply center are different (height). The fixed height design of this cleaning tank is difficult to adjust according to the height and operation requirements of different staff. For tall workers, the height mismatch is easy to cause fatigue during long-term operation (needing to bend over for a long time), which reduces work efficiency. Therefore, this solution, such as Figure 1 and Figure 2 As shown, an instrument cleaning tank for a disinfection supply center includes a cabinet 1, a controller 6 and a faucet 2 (preferably a pull-out type). The controller 6 is embedded in the surface of the cabinet 1, and the top of the cabinet 1 is threadedly connected to the faucet 2. At the same time, an outer cleaning tank 5 that slides with the cabinet 1 is installed on the top of the cabinet 1. The inner cleaning tank 4 is integrally formed inside the outer cleaning tank 5. The inner wall of the inner cleaning tank 4 is engraved with scale lines. The bottom of the inner cleaning tank 4 is connected to a recovery pipe 7. The bottom end of the recovery pipe 7 passes through the outer cleaning tank 5 and the cabinet 1 in sequence and is connected to a recovery box 10 (the recovery box 10 can be replaced with other recycling and processing equipment according to actual application conditions, such as corrosion-resistant plastic barrels or stainless steel barrels, which are convenient for classified recycling). At the same time, Figure 10As shown, a fixed plate 27 is integrally formed on one side of the cabinet 1, on which an air gun 28 and a water gun 29 are placed. The air gun 28 and the water gun 29 are connected to an air pump and a water pump, respectively, so that the staff can use the air gun 28 and the water gun 29 to perform high-pressure flushing on the instruments. This serves as the necessary basic structure of this solution. Secondly, due to the characteristics of instrument cleaning in the disinfection supply center (frequent use of various chemical disinfectants, such as chlorine-containing disinfectants and peracetic acid, which are highly corrosive), the above-mentioned basic structure is made of stainless steel. The alloy elements such as chromium and nickel contained in stainless steel can form a dense passivation film on the surface, which effectively resists the erosion of chemical disinfectants, prevents corrosion damage to structures such as the cabinet 1 and the cleaning tank, and extends the service life of the equipment.

[0050] At the same time, combined Figure 3 As shown, the two diagonal groups at the bottom end of the outer cleaning tank 5 are screwed with a pair of nut seats 9 and a pair of stable seats 801 respectively, and the threaded seats are threadedly connected with screw rods 901 to form a ball screw structure. The stable seats 801 are slidably connected to the stabilizing rod 8, and both ends of the stabilizing rod 8 are screwed to the inner top wall and inner bottom wall of the cabinet 1; the two ends of the two screw rods 901 are rotatably connected to the inner top wall and inner bottom wall of the cabinet 1, and the inner bottom wall of the cabinet 1 is bolted with two motors 902 corresponding to the screw rods 901 and electrically connected to the controller 6. Since the outer cleaning tank 5 is a lifting motion (the screw rods 901 are subjected to force along their axial direction), the output shafts of the motors 902 are keyed to the first bevel gear, and the bottom ends of the two screw rods 901 are screwed to the second bevel gear, and the first bevel gears are meshed with the second bevel gears. The transmission assembly consists of the motor 902, the first bevel gear and the second bevel gear to avoid the motor 902 output shaft being continuously subjected to axial force when it is directly connected to the screw rod 901, thereby improving the safety and rationality of the setting. Furthermore, because the outer cleaning tank 5 continues to move up and down, the middle portion of the recovery pipe 7 is configured as a corrugated structure. When the outer cleaning tank 5 is raised and lowered along the cabinet 1, the positions of the two ends of the recovery pipe 7 are relatively fixed, while the corrugated structure in the middle portion can flexibly change its length and shape by elastically expanding or bending to adapt to the displacement caused by the height change of the outer cleaning tank 5. This prevents the recovery pipe 7 from being subjected to excessive tensile or compressive stress caused by the lifting and pulling of the outer cleaning tank 5, prevents the recovery pipe 7 from being damaged by breakage, deformation, and other damage, and ensures that the cleaning liquid recovery channel is always unobstructed.

[0051] The specific lifting process is as follows: When the staff of the disinfection supply center needs to adjust the height of the cleaning tank, they can input instructions through the controller 6 embedded in the surface of the cabinet 1. After receiving the signal, the controller 6 will send an operating instruction to the corresponding motor 902. The motor 902 is started, and its output shaft drives the first bevel gear connected by the key to rotate. Since the first bevel gear is engaged with the second bevel gear at the bottom of the screw rod 901, the rotation of the first bevel gear will drive the second bevel gear, thereby rotating the screw rod 901. Under the action of the ball screw structure, the nut seat 9 threadedly connected to the screw rod 901 will perform linear motion along the axial direction of the screw rod 901. The nut seat 9 is fixed to the bottom end of the outer cleaning tank 5, thereby driving the outer cleaning tank 5 to move up and down along the stabilizer bar 8. The stabilizer bar 8 plays a guiding and stabilizing role to ensure that the outer cleaning tank 5 is lifted and lowered smoothly. When the outer cleaning tank 5 reaches the set height, the controller 6 will control the motor 902 to stop running and complete the adjustment of the height of the cleaning tank.

[0052] For example, when a worker with a height of 185 cm performs instrument cleaning work, the height of the cleaning tank is raised by 20 cm through the controller 6 to avoid bending over for a long time. After working continuously for 3 hours, the body fatigue is significantly reduced and the work efficiency is improved by about 15% compared with before; while a worker with a height of 155 cm can keep the height of the cleaning tank unchanged (or raise it by about 5 cm), making the operation smoother. When cleaning precision instruments, the operating error rate is reduced from 8% to 3%, significantly improving work quality and efficiency.

[0053] In addition, the cleaning tank in the above-mentioned prior art is difficult to adjust in height. It is also unable to meet the cleaning requirements of some instruments in some disinfection supply centers (which need to be cleaned in a constant temperature cleaning solution). Figure 2 and Figure 4 A number of heating wires 12 are arranged between the outer cleaning tank 5 and the inner cleaning tank 4. The heating wires 12 are arranged in an array along the height direction of the outer cleaning tank 5. A temperature sensor electrically connected to the controller 6 is welded to the bottom wall of the inner cleaning tank 4 for constant temperature control. Secondly, since the recovery pipe 7 passes through the gap between the outer cleaning tank 5 and the inner cleaning tank 4, the heating wires 12 will directly heat the recovery pipe 7 when working. The continuous high temperature will damage the recovery pipe 7, accelerate the aging and deformation of the recovery pipe 7, and also interfere with the actual temperature monitoring in the inner cleaning tank 4. Therefore, the surface of the recovery pipe 7 is surrounded by a heat-insulating ring 1201 located in the gap between the outer cleaning tank 5 and the inner cleaning tank 4.

[0054] The specific heating and temperature control process involves placing instruments to be cleaned in constant-temperature cleaning fluid into the inner cleaning tank 4. The desired cleaning temperature, such as 40°C, is set via controller 6. Upon receiving this command, controller 6 activates the heating wires 12 looped between the outer and inner cleaning tanks 5 and 4. The heating wires 12, arrayed along the height of the outer tank 5, begin to heat evenly, heating the cleaning fluid in the inner cleaning tank 4. A temperature sensor at the bottom of the inner cleaning tank 4 monitors the cleaning fluid temperature in real time and transmits this data back to controller 6. When the temperature sensor detects that the cleaning fluid temperature approaches the set value, such as 39°C, controller 6 reduces the power to heating wire 12, slowing the heating process. When the temperature reaches 40°C, controller 6 stops heating heating wire 12. If the cleaning fluid temperature subsequently drops due to heat loss, the temperature sensor detects this change and transmits a signal to controller 6, which then restarts heating heating wire 12 to maintain the cleaning fluid temperature near the set value, achieving constant temperature control.

[0055] For example, when cleaning precision surgical instruments, which have strict requirements on the cleaning temperature, a constant temperature of 30-37°C is set for cleaning, which can effectively remove stains on the surface of the instruments without damaging the instrument material. After the heating and constant temperature function of the cleaning tank is activated, the temperature fluctuation is controlled within ±0.5°C during the entire cleaning process, and the cleanliness compliance rate of the instruments after cleaning is significantly improved. For example, when handling high-temperature resistant hard metal instruments or using most alkaline cleaning agents, the cleaning liquid temperature is set to 45-50°C. Under the synergistic effect of the heating wire 12 and the temperature sensor, the cleaning liquid always maintains a constant temperature, effectively dissolving stubborn dirt on the surface of the instrument, and improving cleaning efficiency and quality.

[0056] Example 2:

[0057] The difference from the above embodiment is that as the outer cleaning tank 5 rises and falls, there must be a gap between the cabinet 1 and the outer cleaning tank 5 (to ensure smooth lifting and lowering), but generally, after the medical equipment is cleaned by the staff, it will be placed on the top of the cabinet 1 for draining and temporary storage, and then other equipment will be cleaned until the cleaning of the batch of equipment is completed, and then these equipment will be transferred for subsequent operations. When the cleaned equipment is placed on the top of the cabinet 1, there is a high probability that the liquid on the surface of the equipment and the liquid on the hands of the staff will drip onto the top of the cabinet 1. As these liquids increase, they flow at the top of the cabinet 1 and easily flow into the gap between the outer cleaning tank 5 and the cabinet 1. At the same time, for the cleaning tanks in the prior art (such as models such as SZ-QXC200), these liquids may flow back into the cleaning tank as the cleaning liquid continues to flow toward the edge of the cleaning tank. These refluxed cleaning liquids contain dirt, impurities and disinfectants that have consumed some of their effectiveness from the initial cleaning of the equipment surface, which will contaminate the originally clean cleaning liquid in the cleaning tank and reduce the cleaning and disinfection capabilities of the cleaning liquid. When subsequent instruments are cleaned in contaminated cleaning fluid, not only will it be difficult to achieve the ideal cleaning effect, but secondary contamination may also cause the instrument cleaning to fail to meet the standards, affecting the work quality of the disinfection supply center and even posing a potential threat to the health and safety of patients.

[0058] Specifically, this solution, combined with Figure 5 As shown, the top of the cabinet 1 is provided with an isolation boss 14 and a water collecting tank 15 along the circumference of the outer cleaning tank 5 from the inside to the outside; Figure 7 As shown, the top of the outer cleaning tank 5 is integrally formed with a top cover, and the bottom of the top cover is provided with an isolation groove 18 along the circumference of the outer cleaning tank 5, and the isolation groove 18 corresponds to the isolation boss 14. The size of the isolation groove 18 is smaller than the isolation boss 14, ensuring that the top of the isolation boss 14 is under pressure. Figure 6 As shown, the isolation boss 14 is composed of an air bag layer and a fixed seat from top to bottom. The air bag layer is connected to a plurality of air supply channels 17 along the circumference of the fixed seat. The air supply channels 17 are all connected to auxiliary cleaning pipes 11 threadedly connected to the inner top wall of the cabinet 1. The auxiliary cleaning pipes 11 are connected to the recovery pipe 7 at one end away from the isolation boss 14; the water collection tank 15 is evenly distributed with a plurality of water suction pipes 16 along the inner bottom wall and the circumference of the water collection tank 15. The water suction pipes 16 are all connected to the air supply channels 17; the diameter of the water suction pipes 16 is smaller than that of the air supply channels 17.

[0059] The specific process is as follows: When the staff cleans the medical equipment and places it on the top of the cabinet 1 to drain and store temporarily, the liquid dripping from the surface of the equipment and the staff's hands flows on the top of the cabinet 1. When it flows to the external cleaning tank 5, Figure 5As shown, the liquid first passes through the water collecting tank 15, and the water collecting tank 15 collects the liquid and plays a preliminary blocking role. However, when the liquid continues to increase, the liquid flows to the isolation boss 14. Since the isolation boss 14 performs physical blocking, the blocking effect is further improved. At the same time, the isolation boss 14 is close to the water collecting tank 15. One end is an arc surface (such as Figure 6 As shown), the angle between the isolation boss 14 and the surface of the cabinet 1 is avoided, and the liquid that is difficult to clean remains in the angle. The liquid on the surface of the cabinet 1 flows to the water collection tank 15 or moves away from the outer cleaning tank 5 under the action of gravity through the curved surface.

[0060] Specifically, as the outer cleaning tank 5 begins to descend, the integrally formed top cover at the top of the outer cleaning tank 5 moves downward accordingly, and the isolation groove 18 at the bottom of the top cover, along the circumference of the outer cleaning tank 5, gradually overlaps with the isolation boss 14 at the top of the cabinet 1. Because the isolation groove 18 is smaller than the isolation boss 14, after the two come into contact, the airbag layer at the top of the isolation boss 14 begins to be squeezed. As the outer cleaning tank 5 continues to descend, the airbag layer is continuously compressed. The airbag layer is connected to several gas transmission channels 17 along the circumference of the fixed base. During the compression of the airbag layer, the internal gas is squeezed, forming a high-pressure airflow that flows rapidly into the gas transmission channels 17.

[0061] When high-pressure air flows rapidly through the lower end of the suction pipe 16 connected to the air supply channel 17, according to Bernoulli's principle, the gas flow rate at the lower end of the suction pipe 16 accelerates and the pressure decreases, while the atmospheric pressure at the upper end of the suction pipe 16 remains unchanged. Under the action of the pressure difference, suction is generated at the upper end of the suction pipe 16. This suction can quickly draw liquid from the sump 15. The liquid enters the air supply channel 17 through the suction pipe 16, then flows along the air supply channel 17 to the auxiliary cleaning pipe 11 threadedly connected to the top wall of the cabinet 1, and finally discharged into the recovery pipe 7, achieving efficient recovery of the liquid in the sump 15. For example, in daily use at a certain disinfection supply center, a batch of approximately 30 instruments are cleaned and placed on the top of the cabinet 1 to drain. The dripping liquid flows on the surface of the cabinet 1 and is guided into the sump 15 by the isolation boss 14. After the temporary storage of the batch of instruments is complete, the operator lowers the outer cleaning tank 5 via controller 6. During the descent, the airbag layer is squeezed, and the suction force generated by the Bernoulli principle quickly draws in approximately 500ml of liquid from the sump 15 and recycles it into the recovery pipe 7. The entire process takes only 5 seconds, saving manpower and time compared to traditional manual cleaning methods. It also avoids bacterial growth caused by residual liquid, effectively maintaining a clean and hygienic environment around the cleaning tank. It also prevents liquid from seeping into the gap between the cabinet 1 and the outer cleaning tank 5, extending the service life of the cleaning tank equipment and reducing equipment maintenance costs.

[0062] In addition, when the outer cleaning tank 5 is not raised, there is a dead angle between the top cover and the cabinet 1, and some liquids may accumulate here, which is difficult to handle and difficult to find. When it is necessary to clean these liquids, the staff controls the outer cleaning tank 5 to be raised through the controller 6. As the outer cleaning tank 5 rises, the dead angle between the top cover and the cabinet 1 is eliminated. At this time, the staff can clean these liquids more conveniently (for example, wiping with a sterile cloth). When there is a lot of liquid, it can also be introduced into the water collection tank 15, and then the air bag layer of the isolation boss 14 is manually pressed so that the liquid is quickly sucked into the water suction pipe 16 and flows into the recovery box 10. In this way, the cleaning of the liquid in the dead angle is completed, the cleanliness of the entire cleaning tank area is ensured, and the liquid residue is prevented from breeding bacteria and affecting the cleaning quality of the equipment.

[0063] Example 3:

[0064] The difference from the above embodiment is that, Figure 1 As shown, a baffle 19 is integrally formed along the edge of the top of the cabinet 1. Figure 9 As shown, the inner side of the baffle 19 is a concave arc surface. During cleaning, in addition to dripping onto the surface of the outer cleaning tank 5 or near it, some of the liquid splashes with greater inertia and easily flows along the surface of the cabinet 1 to the edge of the cabinet 1. At this time, these liquids move upward along the arc surface on the inner side of the baffle 19, and gravity and friction are used to keep these liquids on the surface of the cabinet 1, reducing the difficulty of subsequent cleaning.

[0065] At the same time, combined Figure 3 and Figure 9 As shown, a cylinder 20 corresponding to the stabilizing seat 801 is installed in the cabinet 1, and a piston is slidably fitted in the cylinder 20. A push rod 21 is integrally formed on the top of the piston. The top of the push rod 21 passes through the top of the cylinder 20 and is connected to the corresponding stabilizing block screw. At the same time, the piston divides the inside of the cylinder 20 from top to bottom into a first cavity 22 and a second cavity 23. The first cavity 22 is connected to a first air pipe 25, and the second cavity 23 is connected to a second air pipe 24.

[0066] The second air pipe 24 is connected to a plurality of air blowing channels 26, such as Figure 9 As shown, the air outlets of the blowing channels 26 are all located above the arc surface of the baffle 19 , and the gas blown from the blowing channels 26 flows from top to bottom along the arc surface. At the same time, the blowing channels 26 are distributed in an array along the perimeter of the baffle 19 .

[0067] like Figure 2 As shown, the inner wall of the inner cleaning tank 4 has several disturbance holes along its circumferential array, and the first air pipe 25 is connected to the disturbance holes. At the same time, an electric valve is installed on the first air pipe 25, and a first one-way valve is installed on the top wall of the first cavity 22 (the flow direction is the outside → the first cavity 22).

[0068] The specific exercise process is as follows:

[0069] For the first cavity 22: when the outer cleaning tank 5 is lifted, the gas in the first cavity 22 is compressed (the second cavity 23 inhales the outside air). After the lifting is completed, the staff can choose to open the electric valve at their own discretion and adjust the degree of opening of the electric valve according to the actual situation. By adjusting the flow rate and duration of the flow from the first cavity 22 to the disturbance hole, when there are many cleaning instruments or the surface attachments are relatively stubborn, the degree of opening of the electric valve can be reduced (with a smaller diameter). At this time, the flow rate of the gas flowing out of the disturbance hole increases, and the time it takes for the compressed gas in the first cavity 22 to be released is also increased, thereby disturbing the cleaning liquid for a longer time. The flowing liquid and the gas ejected in the early stage are used to assist in cleaning the contaminants such as tissue attached to the surface of the instrument. At the same time, due to the characteristics of gas and liquid, it can also play a certain pre-cleaning role for the joints of some instruments (such as the hinge of scissors, etc.). For example, when cleaning toothed hemostatic forceps, small tissue debris is easily left between the teeth, and traditional cleaning requires repeated brushing. After the disturbance holes are activated, gas is ejected from the disturbance holes around the pliers body, and the liquid forms high-frequency vibrations between the teeth, which can peel off more than 95% of the debris within 3 minutes, combined with the chemical action of the cleaning fluid.

[0070] Secondly, since the outer cleaning tank 5 needs to descend, and the first cavity 22 inhales air when descending, it is necessary to prevent the liquid in the inner cleaning tank 4 from flowing out of the first cavity 22 or the first air pipe 25. Therefore, a second one-way valve is installed in the disturbance hole (the flow direction is the first air pipe 25 → the inner cleaning tank).

[0071] For the second cavity 23: when the outer cleaning tank 5 begins to descend (when cleaning is finished), the gas in the second cavity 23 is compressed and ejected along the second air pipe 24 and the blowing pipe. These high-speed gases flow from top to bottom along the curved surface of the baffle 19, blowing the liquid splashed into these areas into the water collection tank 15. The liquids collected by the water collection tank 15 are combined with the movement described in Example 2 to complete centralized recovery and cleaning.

[0072] Obviously, the above embodiments are merely examples for clarity of explanation and are not intended to limit the implementation methods. Those skilled in the art will appreciate that other variations or modifications can be made based on the above description. It is not necessary and impossible to enumerate all implementation methods here. Obvious variations or modifications derived therefrom remain within the scope of protection of the present invention.
