Description

Technical Field

[0001] The present invention relates to the technical field of medical dialysis equipment, and particularly relates to a double-chamber liquid storage barrel for supplying dialysis liquid and a using method thereof. Background Art

[0002] In the dialysis centers of medical institutions, dialysis liquid needs to be prepared and transported to each dialysis machine through pipelines for dialysis use. The liquids supplied by the centralized liquid supply equipment in medical institutions are mainly divided into two types. One is liquid A mainly composed of high-concentration sodium chloride, and the other is mainly sodium bicarbonate solution, which is called liquid B. The sodium chloride concentration in liquid A exceeds 20%. Such a high concentration gives it a good bactericidal effect. It is found through research that common bacteria in dialysis treatment cannot survive in this liquid. Therefore, it can be said that no bacteria grow in it. However, for liquid B, on the contrary, the sodium bicarbonate solution is very prone to bacterial growth. According to the treatment specifications related to hemodialysis, liquid B exposed to air cannot be used after more than 24 hours. In fact, due to the easy growth of bacteria in liquid B, this is also a very crucial content in dialysis microorganism management. Because after the Gram-negative bacteria growing in liquid B die, they will decompose, forming a substance - endotoxin - that has a very great impact on the dialysis quality. And the removal of endotoxin is a fact that requires high costs. Commonly, the ultrafiltration membrane filtration method is used, and the cost of the ultrafiltration membrane is relatively high. Therefore, it is very important how to design the process and technology for centralized liquid supply to avoid the growth of bacteria in liquid B.

[0003] If liquid B needs to be stored, it is necessary to properly kill the bacteria in liquid B and have measures to inhibit the growth of bacteria. Currently, in the centralized dialysis liquid supply system, a liquid storage barrel is generally configured, an ultraviolet disinfection lamp is installed in the liquid storage barrel, and the inside of the liquid storage barrel is cleaned with a disinfectant or a cleaning liquid every day after the machine is used.

[0004] However, in the actual application process, the pipelines for transporting the centralized liquid supply system to the dialysis room are generally long. In a large dialysis center, the supply and return pipelines may be concentrated to reach three or four hundred meters. The liquid B in the pipelines cannot be disinfected by the ultraviolet disinfection lamp, and it is easily contaminated by contacting with air at each outlet. According to the current industry management specifications, it is required that the liquid B pipelines need to be emptied and flushed every day, which will cause a large amount of unused liquid B in the pipelines and the liquid B in the liquid storage barrel to be discarded and emptied. Moreover, due to the inability to accurately control the time of patients getting on and off the machine and the dialysis liquid consumed during treatment on both sides, more liquid B is often prepared for storage in advance, which further exacerbates the waste of the discarded and emptied liquid B in the liquid storage barrel. The amount of liquid wasted each time is about fifty or sixty liters or even more. In the long run, it causes great losses to medical institutions. Summary of the Invention

[0005] In view of the above problems, the present invention provides a double-chamber liquid storage barrel for use in supplying dialysis fluid and a method for using the same.

[0006] In order to achieve the above-mentioned invention purpose, the technical solution adopted by the present invention is as follows:

[0007] In a first aspect, a double-chamber liquid storage barrel for use in supplying dialysis fluid is provided, including a liquid storage barrel and a partition plate arranged inside the liquid storage barrel. The liquid storage barrel is divided into an upper chamber and a lower chamber which are distributed up and down by the partition plate. A lower liquid pipe communicating the upper chamber and the lower chamber is arranged on the liquid storage barrel, and a lower liquid valve is arranged on the lower liquid pipe;

[0008] An upper liquid pipe communicating with the upper chamber is connected to the outer wall of the liquid storage barrel. A disinfection lamp is arranged inside the upper chamber. Respirators communicating with the atmosphere are arranged on both the upper chamber and the lower chamber of the liquid storage barrel;

[0009] A water inlet pipe is connected to the outer wall of the liquid storage barrel, and a water inlet valve is arranged on the water inlet pipe. A liquid supply output pipe communicating with the lower chamber is connected to the bottom of the liquid storage barrel. The end of the liquid supply output pipe far away from the liquid storage barrel is externally connected to the conveying pipeline of the dialysis room, and a liquid supply pump for unidirectionally pumping from the liquid storage barrel to the dialysis room is arranged on the liquid supply output pipe;

[0010] A liquid supply return pipe is further arranged between the conveying pipeline and the upper chamber. A first liquid supply return valve for controlling the opening and closing of the pipeline between the dialysis room conveying pipeline and the upper chamber is arranged on the liquid supply return pipe. A first discharge pipe externally connected to a drain outlet is arranged on the liquid supply return pipe, and a first discharge valve is arranged on the first discharge pipe.

[0011] Further, the bottom end of the lower liquid pipe extends into the lower chamber, and a float valve for controlling the on-off of the lower liquid pipe is arranged at the end of the lower liquid pipe extending into the lower chamber.

[0012] Further, a spray pipe is connected to the liquid supply output pipe. The other end of the spray pipe extends into the lower chamber and is connected with a spray head. A spray valve is arranged on the spray pipe, and the liquid supply pump is located between the liquid storage barrel and the spray pipe on the liquid supply output pipe.

[0013] Further, the spray head is located above the float valve.

[0014] Further, the liquid supply return pipe is connected to the lower chamber through a branch pipe, and a second liquid supply return valve is arranged on the branch pipe between the liquid supply return pipe and the lower chamber.

[0015] Further, a second discharge pipe externally connected to a drain outlet is arranged on the liquid supply output pipe, and a second discharge valve is arranged on the second discharge pipe. The horizontal height of the second discharge pipe is not higher than that of the conveying pipeline.

[0016] Further, liquid level sensors are arranged in both the upper chamber and the lower chamber.

[0017] Furthermore, the partition in the liquid storage barrel is inclined, and the end of the liquid downcomer for communicating with the upper chamber is located on the side with a lower height of the partition.

[0018] In a second aspect, a method for using a double-chamber liquid storage barrel for dialysis fluid supply is provided, which is applied to the double-chamber liquid storage barrel for dialysis fluid supply provided in the first aspect of the present application, and includes:

[0019] When emptying and cleaning the liquid storage barrel and the pipeline every day, open the liquid supply return pipe between the upper chamber and the dialysis chamber delivery pipeline, and pump the remaining sodium bicarbonate solution in the lower chamber through the delivery pipeline of the dialysis chamber to the upper chamber until there is no obvious solution remaining in the lower chamber;

[0020] Open the water inlet pipe to inject cleaning water into the lower chamber, and the injection volume is slightly less than the rated liquid storage volume of the delivery pipeline. Pump the cleaning water in the lower chamber through the delivery pipeline to the upper chamber until there is no obvious solution remaining in the lower chamber;

[0021] Close the liquid supply return pipe and open the spray pipe. Continuously clean the inner wall of the lower chamber through the liquid supply pump and the spray head as the first-level cleaning. After a certain period of time, close the spray pipe and open the first discharge pipe to drain the cleaning water during the first-level cleaning process into the delivery pipeline. Then, continue to inject water into the lower chamber to drain the cleaning water in the delivery pipeline, and then close the first discharge pipe and open the branch pipe. Continuously pump the cleaning water to clean the delivery pipeline as the second-level cleaning. Repeat the first-level cleaning and the second-level cleaning processes several times to clean the lower chamber and the delivery pipeline;

[0022] Before the treatment starts the next day, perform the above first-level cleaning and second-level cleaning processes once to wash away the bacteria that may have grown overnight in the pipeline. Then open the liquid downcomer to inject the solution in the upper chamber into the lower chamber, and then fill the solution in the lower chamber into the delivery pipeline to push the cleaning water in the delivery pipeline to be discharged from the first discharge pipe, ensuring that the delivery pipeline is filled with the solution. Then close the first discharge pipe, and the hemodialysis machine in the dialysis chamber can work normally.

[0023] Furthermore, when supplying liquid to the dialysis chamber, the prepared sodium bicarbonate solution is injected into the upper chamber through the upper liquid pipe, and the solution is sterilized by the disinfection lamp;

[0024] Open the liquid downcomer, so that the sodium bicarbonate solution passes through the lower chamber and is pumped by the liquid supply pump along the liquid supply output pipe to the delivery pipeline of the dialysis chamber for use by the hemodialysis machine.

[0025] The beneficial effects of the present invention are as follows: When emptying and cleaning the liquid storage barrel every day, first close the lower liquid pipe, and then pump the sodium bicarbonate solution in the lower chamber of the liquid storage barrel completely into the delivery pipeline of the dialysis chamber, so that there is no solution residue in the lower chamber. Then, inject cleaning water into the lower chamber and pump the cleaning water to the dialysis chamber to push the solution in the delivery pipeline back into the upper chamber. The solution is sterilized and preserved by the disinfection lamp. Then, close the liquid supply return pipe and open the first discharge pipe, and the cleaning water can clean the delivery pipeline. Before using the dialysis machine the next day, input the solution into the lower chamber and push the cleaning water in the delivery pipeline out through the first discharge pipe, and then close the first discharge pipe, and the hemodialysis machine can be normally supplied with liquid, reducing the waste of sodium bicarbonate solution by medical institutions every day.

[0029] In order to better understand the above technical solutions, the above technical solutions will be described in detail below in conjunction with the accompanying drawings of the specification and specific embodiments.

[0030] Embodiment 1

[0031] Embodiment 1 of the present application discloses a double-chamber liquid storage barrel for supplying and using dialysis fluid. Refer to Figure 1, including a liquid storage barrel 1. A partition 13 is provided inside the liquid storage barrel 1. The inside of the liquid storage barrel 1 is divided into an upper chamber 20 and a lower chamber 21 which are distributed up and down by the partition 13. An upper liquid pipe 501 communicating with the upper chamber 20 of the liquid storage barrel 1 is connected to the outer wall of the liquid storage barrel 1. Through the upper liquid pipe 501, a sodium bicarbonate solution can be injected into the upper chamber 20 of the liquid storage barrel 1. An upper liquid valve 50 is installed on the upper liquid pipe 501, and the upper liquid pipe 501 can be opened and closed through the upper liquid valve 50. A lower liquid pipe 511 is installed on the outer wall of the liquid storage barrel 1. One end of the lower liquid pipe 511 communicates with the upper chamber 20 of the liquid storage barrel 1 and the other end communicates with the lower chamber 21 of the liquid storage barrel 1. A lower liquid valve 51 is installed on the lower liquid pipe 511, and the lower liquid pipe 511 can be opened and closed through the lower liquid valve 51, so that the solution in the upper chamber 20 flows into the lower chamber 21.

[0032] A disinfection lamp 60 is installed in the upper chamber 20. The disinfection lamp 60 can specifically be an ultraviolet disinfection lamp 60, which is used to kill bacteria in the sodium bicarbonate solution in the upper chamber 20 of the liquid storage barrel 1 and inhibit the growth of bacteria. Two air breathers 12 are provided on the outer wall of the liquid storage barrel 1. The two air breathers 12 communicate with the upper chamber 20 and the lower chamber 21 respectively. The air breathers 12 communicate with the atmosphere. The air breathers 12 are used to balance the atmospheric pressure in the upper chamber 20 and the lower chamber 21. A filter element is installed in the air breathers 12. Through the filter element, bacteria and dust in the atmosphere can be isolated to avoid impurities entering the liquid storage barrel 1 and polluting the solution.

[0033] A water inlet pipe 551 is connected to the lower part of the liquid storage barrel 1. The water inlet pipe 551 communicates with the lower chamber 21. Through the water inlet pipe 551, cleaning water can be injected into the lower chamber 21. The cleaning water can be clean water, and the clean water is reverse osmosis water for dialysis. A liquid supply output pipe 301 is connected to the bottom of the liquid storage barrel 1. One end of the liquid supply output pipe 301 communicates with the lower chamber 21, and the other end extends towards the dialysis room 40 and is connected to a delivery pipeline 41 connecting a hemodialysis machine in the dialysis room 40. A liquid supply output valve 30 and a liquid supply pump 32 are installed on the liquid supply output pipe 301. The liquid supply output valve 30 is used to open and close the liquid supply output pipe 301, and the liquid supply pump 32 is used for unidirectional pumping from the liquid storage barrel 1 towards the dialysis room 40.

[0034] A liquid supply return pipe 361 is also provided between the delivery pipeline 41 and the upper chamber 20. A first liquid supply return valve 36 is installed on the liquid supply return pipe 361. The first liquid supply return valve 36 can control the opening and closing of the pipeline between the delivery pipeline 41 in the dialysis room 40 and the upper chamber 20. A first discharge pipe 351 is also provided on the liquid supply return pipe 361 between the first liquid supply return valve 36 and the dialysis room 40. One end of the first discharge pipe 351 communicates with the liquid supply return pipe 361, and the other end is externally connected to a drain port 34. A first discharge valve 35 for controlling the opening and closing of the first discharge pipe 351 is installed on the first discharge pipe 351.

[0035] Further, in order to prevent the solution from overflowing from the breathing apparatus 12 when the liquid fills the lower chamber 21 due to the failure to close the lower liquid valve 51 in time when injecting the solution from the upper chamber 20 into the lower chamber 21, in the embodiment of the present application, the lower end of the lower liquid pipe 511 extends into the lower chamber 21, and a float valve 52 is installed at the part of the lower liquid pipe 511 extending into the lower chamber 21. The float valve 52 can control the on-off of the lower liquid pipe 511. When the liquid level in the lower chamber 21 rises to the position of the float valve 52, the float valve 52 operates to close the lower liquid pipe 511, so as to limit the continuous flow of the solution in the upper chamber 20 into the lower chamber 21.

[0036] Further, liquid level sensors 11 are installed in both the upper chamber 20 and the lower chamber 21 on the liquid storage barrel 1. The liquid level sensors 11 are connected to terminals such as a computer. Through the liquid level sensors 11, the liquid level heights in the upper chamber 20 and the lower chamber 21 in the liquid storage barrel 1 can be obtained. Moreover, the valves on the pipelines in each connection link between the liquid storage barrel 1 and the dialysis chamber 40 can all be electronic valves, and the electronic valves are electrically connected to a central controller such as a computer. When the liquid level in the upper chamber 20 or the lower chamber 21 measured by the liquid level sensor 11 is too high, the valve on the liquid inlet pipeline of the target chamber can be immediately controlled to close, effectively avoiding the overflow of the liquid in each chamber of the liquid storage barrel 1.

[0037] Further, the installation position of the high liquid level sensor 11 in the lower chamber 21 is higher than the highest liquid level controlled by the float valve 52. When the float valve 52 fails and the water inlet gets out of control, the liquid level rises to trigger the liquid level sensor 11, and the system closes the lower liquid valve 51 in time according to the sensor signal, thereby increasing the safety.

[0038] In order to accurately master the liquid level height in the lower chamber 21, in the embodiment of the present application, a hydraulic sensor 211 can also be installed inside the lower chamber 21. The hydraulic sensor 211 is used to detect the remaining liquid in the lower chamber 21. Especially when the liquid level in the lower chamber 21 is lower than the high level, it can accurately know the remaining liquid in the chamber, which is used to calculate the remaining endurance time when the liquid in the lower chamber 21 is continuously pumped.

[0039] Further, a spray pipe 541 is connected to the liquid supply output pipe 301. Specifically, the spray pipe 541 is connected to the water outlet end side of the liquid supply pump 32 on the liquid supply output pipe 301. One end of the spray pipe 541 far from the liquid supply output pipe 301 extends into the lower chamber, and a spray head 53 is connected inside the lower chamber. A spray valve 54 for controlling the opening and closing of the spray pipe 541 is installed on the spray pipe 541. After injecting cleaning water into the lower chamber and pushing the solution in the conveying pipeline 41 into the upper chamber 20, close the first discharge valve 35 on the first discharge pipe 351, open the spray valve 54, and continue to pump by the liquid supply pump 32, then the cleaning water can be sprayed out from the spray head 53 through the spray pipe 541 to clean the inner wall of the lower chamber 21, ensuring that there is no solution residue inside the lower chamber 21.

[0040] In order to prevent the solution or the cleaning water from submerging the spray head 53 and causing liquid residue in the spray pipe 541, in the embodiment of the present application, the spray head 53 should be located above the float valve 52.

[0041] After the cleaning water pushes the solution back into the upper chamber 20, in order to thoroughly clean the complex conveying pipeline 41 in the dialysis chamber 40, it is necessary to continuously pump the cleaning water into the conveying pipeline 41. In order to prevent waste of water resources, in the embodiment of the present application, a branch pipe 311 is further provided on the liquid supply return pipe 361. The branch pipe 311 communicates with the lower chamber 21, and a second liquid supply return valve 31 is provided on the branch pipe 311 to control the opening and closing of the branch pipe 311. By opening the second liquid supply return valve 31, a loop is formed among the lower chamber 21, the liquid supply output pipe 301, the conveying pipeline 41, the liquid return pipe, and the branch pipe 311, and the liquid supply pump 32 continuously pumps the cleaning water, thereby continuously cleaning the conveying pipeline 41.

[0042] When the liquid storage bucket 1 is not used for a long time, in order to completely drain the cleaning water in the conveying pipeline 41, in the embodiment of the present application, a second discharge pipe 331 is further connected to the liquid supply output pipe 301. The second discharge pipe 331 is externally connected to a drain port 34. The horizontal height of the second discharge pipe 331 should not be higher than the horizontal height of the conveying pipeline 41, and a second discharge valve 33 is installed on the second discharge pipe 331. By opening the second discharge valve 33, the cleaning water in the conveying pipeline 41 can flow back under its own weight and be discharged from the second discharge pipe 331.

[0043] Furthermore, the partition 13 in the liquid storage bucket 1 can be set to be inclined. One end of the liquid down pipe 511 for communicating with the upper chamber 20 is located on the side with a lower height of the partition 13, so that the solution in the upper chamber 20 can all flow into the lower chamber 21.

[0044] Furthermore, a flow switch 321 is further installed on the liquid supply output pipe 301. The flow switch 321 is installed close to the liquid supply pump 32 and is electrically connected to the liquid supply pump 32. When the flow switch 321 measures that the flow rate in the liquid supply output pipe 301 is lower than the set value, it controls the liquid supply pump 32 to stop, which can effectively prevent the liquid supply pump 32 from continuously idling and play a protective role for the liquid supply pump 32.

[0045] The implementation principle of a dual-chamber liquid storage barrel for dialysis fluid supply in an embodiment of this application is as follows: Sodium bicarbonate solution is injected into the upper chamber 20, sterilized by a sterilization lamp 60, and then injected into the lower chamber 21. Then, it is pumped by a liquid supply pump 32 to a delivery pipeline 41 for use by each hemodialysis machine in a dialysis room 40. When emptying and cleaning the liquid storage barrel 1, first close the lower liquid valve 51. The liquid supply pump 32 pumps all the solution in the lower chamber 21 up to the upper chamber 20 until there is no obvious solution left in the lower chamber 21. Then, clean water is injected into the lower chamber 21 through a water inlet pipe 551. The water injection volume should be approximately the rated capacity of the delivery pipeline 41. Then, the liquid supply pump 32 pumps the clean water in the lower chamber 21 into the delivery pipeline 41 to push the solution into the upper chamber 20. The clean water is left in the delivery pipeline 41. Under the action of the sterilization lamp 60, the solution returned to the upper chamber 20 remains fresh, effectively reducing solution waste. Before using the hemodialysis machine again, open the first discharge valve 35, inject solution into the lower chamber 21, and then pump the solution to the delivery pipeline 41 to discharge the clean water from the first discharge pipe 351. In addition to being used in the preparation process of dialysis fluid in medical institutions, this dual-chamber liquid storage barrel is also applicable to solutions that need to be temporarily prepared and are prone to bacterial growth and deterioration in the medical field and various production fields.

[0046] Embodiment 2

[0047] Refer to Figure 2 , an embodiment of this application discloses a method for using a dual-chamber liquid storage barrel for dialysis fluid supply, which is applied to a dual-chamber liquid storage barrel for dialysis fluid supply proposed in Embodiment 1 of this application. The method for use includes:

[0048] S01. When supplying liquid to the dialysis room 40 for the first time, open the upper liquid valve 501, inject the prepared sodium bicarbonate solution into the upper chamber 20 through the upper liquid pipe 501, and sterilize and preserve the solution by the sterilization lamp 60.

[0049] S02. Open the lower liquid valve 51 to open the lower liquid pipe 511, and open the liquid supply output valve 30 and the liquid supply pump 32, so that the sodium bicarbonate solution passes through the lower chamber 21 and is pumped by the liquid supply pump 32 along the liquid supply output pipe 301 to the delivery pipeline 41 of the dialysis room 40 for use by the hemodialysis machine.

[0050] S03. When emptying and cleaning the liquid storage barrel 1 and the pipeline every day, open the liquid supply output valve 30, the first liquid supply return valve 36, and the liquid supply pump 32, so that the liquid supply return pipe 361 between the upper chamber 20 and the delivery pipeline 41 of the dialysis room 40 is opened. The remaining sodium bicarbonate solution in the lower chamber 21 is pumped through the delivery pipeline 41 of the dialysis room 40 to the upper chamber 20 by the liquid supply pump 32 until there is no obvious solution left in the lower chamber 21.

[0051] Among them, due to the presence of the hydraulic sensor 211 in the lower chamber 21 and the installation of the flow switch 321 on the liquid supply output pipe 301, the liquid supply pump 32 can be continuously pumped until the liquid pressure in the lower chamber 21 measured by the hydraulic sensor 211 is zero or the flow switch 321 controls the liquid supply pump 32 to automatically stop. This is regarded as no obvious liquid remaining in the lower chamber 21. The subsequent process of pushing and discharging the cleaning water in the lower chamber 21 is the same.

[0052] S04. Open the water inlet valve 55 to open the water inlet pipe 551, inject cleaning water into the lower chamber 21, and the injection volume is slightly less than the rated liquid storage capacity of the conveying pipeline 41. This rated liquid storage capacity can be accurately calculated according to the length of the liquid supply output pipe 301 and the conveying pipeline 41. By starting the liquid supply pump 32, pump the cleaning water in the lower chamber 21 through the conveying pipeline 41 to the upper chamber 20 until there is no obvious liquid remaining in the lower chamber 21. During the process of pumping the cleaning water, the sodium bicarbonate solution originally located in the conveying pipeline 41 is pushed into the upper chamber 20 by the cleaning water.

[0053] S05. Close the first liquid supply return valve 36 and open the spray valve 54 to close the liquid supply return pipe 361 and open the spray pipe 541. The water inlet pipe 551 continuously supplies cleaning water to the lower chamber 21. Through the pumping of the liquid supply pump 32, the cleaning water passes through the spray pipe 541 and sprays out from the spray head 53 to continuously clean the inner wall of the lower chamber 21, which is used as the primary cleaning.

[0054] After the primary cleaning lasts for a certain period of time, close the spray valve 54 and open the first discharge valve 35 to close the spray pipe 541 and open the first discharge pipe 351. Continue to supply water to the lower chamber 21 from the water inlet pipe 551. Through the pumping of the liquid supply pump 32, the cleaning water pushes the cleaning water in the primary cleaning process through the conveying pipeline 41 and discharges it from the first discharge pipe 351. Then, close the first discharge valve 35 and open the second liquid supply return valve 31, continuously inject water into the lower chamber 21 and pump it, so that the cleaning water circulates between the lower chamber 21 and the conveying pipeline 41 to clean the conveying pipeline 41 and use it as the secondary cleaning.

[0055] Repeat the primary cleaning process and the secondary cleaning process several times to clean the lower chamber 21 and the conveying pipeline 41 thoroughly.

[0056] S06. Before the start of the next-day treatment, perform the above-mentioned primary cleaning and secondary cleaning processes once to rinse off the bacteria that may have grown overnight in the pipeline. After completing the cleaning process, first open the liquid supply output valve 30 and the first discharge valve 35, and drain the cleaning water in the lower chamber 21 into the delivery pipeline 41 through the liquid supply pump 32 until there is no obvious liquid remaining in the lower chamber 21. Then open the lower liquid valve 51, inject the solution in the upper chamber 20 into the lower chamber 21 through the lower liquid pipe 511, and then pump the solution in the lower chamber 21 to the delivery pipeline 41 to push the cleaning water in the delivery pipeline 41 to be completely discharged from the first discharge pipe 351, ensuring that the delivery pipeline 41 is filled with the solution. Then close the first discharge valve 35, and the hemodialysis machine in the dialysis room 40 can work normally.

[0057] Embodiment 3

[0058] The system composed of the double-chamber liquid storage barrel provided in this application and the delivery pipeline 41 in the dialysis room 40 needs to be disinfected regularly. During regular disinfection, the upper liquid valve 50, the water inlet valve 55, and the lower liquid valve 51 are opened, and the disinfectant solution and the cleaning water can enter the upper chamber 20 through the upper liquid pipe 501. A small amount of disinfectant solution also enters the lower chamber 21 through the valve, aiming to disinfect and clean the pipeline of the water inlet pipe 551. Considering that the upper chamber 20 is only used to store a small amount of remaining liquid, generally less than that in the lower chamber 21, and the designed volume is below 100L, the disinfectant solution and the cleaning water can be directly used to fill the upper chamber 20 for disinfection and cleaning, so there is no need to configure the spray head 53.

[0059] The disinfection process is as follows:

[0060] S11. The disinfectant solution is pumped into and fills the upper chamber 20 through the upper liquid pipe 501 by the pre-stage liquid preparation system. After the disinfectant solution acts on the inner wall of the upper chamber 20 for a certain period of time, it is put into the lower chamber 21 through the lower liquid pipe 511, and then the liquid supply output valve 30, the spray valve 54, and the liquid supply pump 32 are opened to spray the lower chamber 21.

[0061] S12. After spraying the lower chamber 21 for a period of time, open the first discharge valve 35, close the spray valve 54, use the newly injected disinfectant solution to displace the waste liquid in the delivery pipeline 41, and then open the first liquid supply return valve 36 in sequence, close the first discharge valve 35, and let the disinfectant solution fill the liquid supply return pipe 361 to clean the liquid supply return pipe 361.

[0062] S13. After cleaning the liquid supply return pipe 361 for a period of time, finally open the second liquid supply return valve 31 to let the disinfectant solution circulate through the branch pipe 311 for a certain period of time to clean the branch pipe 311.

[0063] After the cleaning of each pipeline is completed, open the first drain valve 35 and inject an appropriate amount of new disinfectant into the lower chamber 21.
