Description

Technical Field

[0001] This invention relates to the field of dialysis equipment technology, and in particular to a method for cleaning and disinfecting dialysis equipment. Background Technology

[0002] In the field of dialysis, it is often necessary to clean and disinfect the tubing of dialysis equipment after dialysis using cleaning and disinfecting agents such as sodium hypochlorite solution, citric acid solution, or acetic acid-based solution. Existing technologies typically employ the following method for cleaning and disinfection: Patent document CN103830756B describes a method for drawing disinfectant into a hemodialysis machine, which involves using an additional disinfectant tank to draw in disinfectant for disinfection. However, storing the disinfectant in a separate tank leads to inconvenient transportation, and the disinfectant tank needs to be connected to the hemodialysis machine for disinfection, which is also inconvenient. Furthermore, different hemodialysis machines require different disinfectant concentrations for cleaning and disinfection; a concentration that is too low will result in poor effectiveness. Summary of the Invention

[0003] The purpose of this invention is to provide a method for cleaning and disinfecting dialysis equipment, which facilitates transportation and operation and improves the cleaning and disinfection effect.

[0004] To achieve this objective, the present invention adopts the following technical solution:

[0005] A method for cleaning and disinfecting a dialysis device is provided. The dialysis device includes a dialysate pipeline, a power pump, a cleaning container, a detection module, and a suction rod. The power pump provides power to allow the suction rod to introduce external dialysate into the dialysate pipeline. Solid reagents are added to the cleaning container to form a reagent solution. The detection module is used to detect the concentration of the reagent solution in the cleaning container. The cleaning and disinfection method further includes:

[0006] The detection module detects whether the concentration of the reagent solution meets the requirements;

[0007] If yes, then begin the cleaning and / or disinfection process.

[0008] In some possible implementations, the cycle time for cleaning and / or disinfection is preset, and after the power pump is turned on, the following steps are also included:

[0009] The detection module detects whether the concentration of the reagent solution reaches a preset value;

[0010] If yes, then the cycle time for cleaning and / or disinfection will begin to be counted until the preset cycle time is reached.

[0011] In some possible implementations, after the cycle time is preset and the power pump is turned on, the following steps are also included:

[0012] After the cleaning and disinfection procedure begins or the cleaning and disinfection time is recorded, the detection module detects whether the concentration of the reagent solution changes.

[0013] No, then the cleaning and / or disinfection cycle time will begin to be counted.

[0014] In some possible implementations, the detection module detects whether the concentration of the reagent solution reaches a preset value;

[0015] If the detection module detects that the concentration of the reagent solution has not reached the preset value within a preset time, the power pump will be turned off.

[0016] After being prompted or alerted, the user adds the solid reagent into the cleaning container to form a reagent solution.

[0017] In some possible implementations, it also includes:

[0018] The detection module detects whether the concentration of the reagent solution is zero;

[0019] If so, the user will add the solid reagent into the cleaning container to form a reagent solution after being prompted or alerted.

[0020] In some possible implementations, it also includes:

[0021] If the solid reagent is added in multiple doses, the detection module checks whether the concentration of the reagent solution is zero. If not, the detection module checks whether the concentration of the reagent solution has reached a preset value. When the preset value is reached, the cleaning and / or disinfection cycle time is started; or

[0022] If the solid reagent is dispensed once, the detection module checks whether the concentration of the reagent solution is zero. If not, the cycle time for cleaning and / or disinfection is started.

[0023] In some possible implementations, including:

[0024] Solid reagents are added into the cleaning container to form a reagent solution, and the suction rod is inserted into the cleaning container;

[0025] The detection module detects whether the concentration of the reagent solution meets the requirements;

[0026] Yes, then the cleaning and / or disinfection procedure begins: turn on the power pump so that the suction rod introduces the reagent solution into the dialysate line for cleaning and / or disinfection.

[0027] In some possible implementations, two suction rods are provided, two cleaning containers are provided, the two suction rods are respectively inserted into the two cleaning containers, and an accelerator pump is provided between the two cleaning containers. Before turning on the power pump, the cleaning and disinfection method further includes:

[0028] Turn on the acceleration pump to circulate the liquid in the two cleaning containers and accelerate the dissolution of the solid reagent;

[0029] After a preset time has elapsed since the solid reagent was added to the cleaning container, the acceleration pump is turned off.

[0030] In some possible implementations, the dialysis apparatus further includes a degassing module connected to the dialysate line, the degassing module being selectively connected to the cleaning container via a second connecting line.

[0031] The cleaning and disinfection method further includes sealing the cleaning container, and after sealing the cleaning container and before turning on the power pump, it further includes:

[0032] The degassing module and the cleaning container are connected, and the gas generated during the dissolution of the solid reagent is discharged through the degassing module.

[0033] In some possible implementations, the degassing module includes a degassing pump capable of providing negative pressure to the second connecting pipeline. The second connecting pipeline is equipped with a valve that allows for selective connection of the second connecting pipeline during cleaning and / or disinfection of the dialysate pipeline.

[0034] The valve is opened according to the set cleaning and / or disinfection procedure to clean and / or disinfect the second connecting pipeline.

[0035] In some possible implementations, the dialysis device further includes a notification module and a control system, the control system and the notification module being communicatively connected.

[0036] Before adding the solid reagent into the cleaning container to form a reagent solution, the cleaning and disinfection method further includes:

[0037] Start the control system to begin the cleaning and disinfection process;

[0038] The control system controls the prompting module to prompt the user to add solid reagents into the cleaning container.

[0039] In some possible implementations, the solid reagent is in the form of flakes, cones, columns, blocks, spheres, powders, or small granules; or, the solid reagent is in the form of flakes, cones, columns, blocks, or spheres.

[0040] and / or

[0041] The solid reagent includes an effervescent component.

[0042] The beneficial effects of this invention are:

[0043] This invention provides a method for cleaning and disinfecting dialysis equipment. It eliminates the need for an external cleaning and disinfection reagent container; the user simply adds the solid cleaning and disinfection reagent into the container to initiate the cleaning and disinfection process, simplifying the procedure and reducing costs. Directly adding the solid reagent into the container is convenient, avoids liquid storage, and facilitates transportation. Simply insert the suction rod into the container and turn on the pump to perform cleaning and disinfection, simplifying the process and making operation easy. Furthermore, by incorporating a detection module, the concentration of the reagent solution is pre-tested before cleaning and disinfection begins. The cleaning and disinfection process only commences when the concentration meets the requirements, ensuring effective cleaning and disinfection. Attached Figure Description

[0057] Example 1

[0058] This embodiment provides a dialysis device 100, such as Figure 1As shown, the dialysis equipment 100 includes a dialysate line 101, a first connecting line 107, a power pump 102, and a suction rod 103. The suction rod 103 and the dialysate line 101 are connected via the first connecting line 107. The power pump 102 is located in the first connecting line 107 and provides power to allow the suction rod 103 to draw liquid into the dialysate line 101. The dialysis equipment 100 includes a cleaning container 200 and a reagent container 300. Solid reagents are added to the cleaning container 200 to form a reagent solution, and the reagent container 300 holds the dialysate (or concentrate). The suction rod 103 can be selectively inserted into either the cleaning container 200 or the reagent container 300. The suction rod 103 is inserted into the reagent container 300 for dialysis and inserted into the cleaning container 200 for cleaning and disinfection. No external cleaning and disinfection reagent container is required; the user simply adds solid cleaning and disinfection reagents to the cleaning container 200 to perform the cleaning and disinfection process, simplifying the process and reducing costs.

[0059] Furthermore, the dialysis device 100 also includes functional modules such as a heat exchange module 110, a heating module 111, a mixing module 112, a fluid balance module 113, and a blood leakage detection module 114, as well as necessary pumps, valves, and pipelines. The dialysate pipeline 101 is used to connect the above structures. Its specific structure, connection method, and working principle are all based on existing technology and will not be described in detail here. Furthermore, some dialysis devices 100 with ultrafiltration function also include an ultrafiltration control module.

[0060] This embodiment also provides a method for cleaning and disinfecting dialysis equipment, used to clean and disinfect the aforementioned dialysis equipment 100. For example... Figure 2 As shown, the cleaning and disinfection methods include:

[0061] S100: Put the solid reagent into the cleaning container 200 to form a reagent solution, and insert the suction rod 103 into the cleaning container 200;

[0062] S200. Turn on the power pump 102 so that the suction rod 103 can introduce the reagent solution into the dialysate line 101 for cleaning and / or disinfection.

[0063] Solid reagents can be directly added to the cleaning container 200, which is convenient to operate and avoids the storage and transportation of cleaning or disinfection liquids. Solid reagents are also easy to transport. The suction rod 103 is inserted into the cleaning container 200. After the solid reagent dissolves, the power pump 102 can be turned on to achieve cleaning and disinfection, simplifying the process and making operation simple.

[0064] In one embodiment, the dialysis device 100 further includes a housing with an opening and a cover abutting the opening, the cover having a motion sensor, and a cleaning container 200 disposed within the housing. Further, prior to step S100, the device includes:

[0065] S110. Open the lid. Generally, the lid is fixedly connected to the outer casing of the dialysis equipment, and the suction rod 103 is inserted into the cleaning container 200 through the opening.

[0066] Specifically, during normal treatment, when the suction rod 103 is inserted into the medicine container 300, the opening is sealed with the aforementioned cap, thereby isolating the cleaning container 200 from the outside through the outer shell and the cap, thus achieving a protective function.

[0067] In another embodiment, the suction rod 103 is provided with a screw cap, and further, between step S100 and step S200, the following is also included:

[0068] S120. Use a screw cap to seal the opening of the cleaning container 200 to prevent foreign objects from entering and affecting the quality of the reagents.

[0069] Specifically, during normal treatment, when the suction rod 103 is inserted into the medicine container 300, the medicine container 300 is sealed with the aforementioned screw cap.

[0070] Solid reagents come in flake, cone, column, block, spherical, powder, or granular forms, facilitating transportation and control of usage. Preferably, the solid reagent is in larger block form to avoid spillage during application, as with powder or granular forms. Flake, cone, block, or spherical forms are preferred to reduce the number of applications. Columns can be chosen if a sufficient quantity needs to be applied at once. When the solid reagent is in powder or granular form, for quantitative application, the amount to be applied each time can be individually packaged. The concentration of the cleaning and disinfecting agent is configured according to requirements, i.e., the ratio of solid reagent to solvent. The required amount of solid reagent is converted into the number of blocks or individual packages. For example, one block of solid reagent can be prepared as the amount needed for one cleaning and disinfection cycle, facilitating control of the cleaning and disinfecting solution concentration and preventing excessively high or low concentrations. The concentration of the dissolved reagent solution (cleaning agent or disinfectant) is based on existing technology and will not be elaborated further.

[0071] As an optional implementation, the cleaning and disinfecting agent is an agent capable of cleaning or disinfecting dialysis machine tubing, such as sodium hypochlorite and citric acid commonly used in the dialysis field, or other agent components capable of cleaning and disinfection. Preferably, the solid reagent includes components capable of effervescence, such as effervescent disintegrants, specifically citric acid and NaHCO3, or tartaric acid and NaHCO3. When the cleaning or disinfecting agent and the effervescent disintegrant have the same components, the content of these same components must simultaneously meet the requirements for both the amount needed in preparing the cleaning or disinfecting agent and the amount needed for the effervescent reaction. For example, when the cleaning or disinfecting agent used is citric acid, and the effervescent disintegrant includes citric acid, the citric acid in the effervescent disintegrant is calculated and added separately, i.e., it needs to be more than the amount of citric acid required in preparing the cleaning or disinfecting agent, and the excess amount is used for the effervescent reaction. In addition to the components with cleaning and disinfection functions and the components with effervescent functions mentioned above, other necessary excipients, such as binders, can be added to prepare the solid reagent in block or small granule form.

[0072] Furthermore, such as Figure 1 As shown, two suction rods 103 are provided, one each in the cleaning container 200 and the medicine container 300. The two suction rods 103 are inserted into the two medicine containers 300 or the two cleaning containers 200, respectively. Solid reagents are added to the two cleaning containers 200 to accelerate their dissolution. The two suction rods 103 are inserted into the two cleaning containers 200 to improve cleaning and disinfection efficiency. The dimensions of the interface and internal cavity of the cleaning container 200 can be appropriately increased to facilitate the addition of solid reagents.

[0073] A filter screen is provided at the end of the suction rod 103 away from the first connecting pipe 107 to prevent undissolved and large solid reagents from entering the suction rod 103 and causing blockage.

[0074] like Figure 1 and Figure 3 As shown, the dialysis apparatus 100 also includes a detection module 105, which is located in the dialysate line 101 and / or the first connecting line 107, and is used to detect the concentration of the dialysate or reagent solution. The cleaning and disinfection method also includes:

[0075] S300, detection module 105 detects whether the concentration of the reagent solution meets the requirements;

[0076] If yes, then begin the cleaning and / or disinfection process.

[0077] The required concentration of the reagent solution specifically refers to a set range. The cleaning and disinfection process involves the circulation of the cleaning and disinfection reagent within the dialysate tubing. While cleaning and disinfection can still occur if the concentration does not reach the set value, the effect will be less effective. Therefore, reaching the set concentration value marks the beginning of the formal cleaning and disinfection procedure. Maintaining the correct reagent solution concentration ensures the quality of cleaning and / or disinfection.

[0078] Optionally, the detection module 105 includes a conductivity sensor, which can be installed on the dialysate line 101 or the first connecting line 107 to detect the concentration of the reagent solution.

[0079] Optionally, the dialysis device 100 includes an alarm system or a notification module.

[0080] When the concentration of the detection reagent solution in detection module 105 does not meet the requirements, there are two possibilities:

[0081] One possibility is that the solid reagent was not added in time. If the reagent is insufficient, the detection module 105 will not detect any change in concentration, and the concentration will remain below the set threshold. In this case, the system will issue an alarm, reminding the user to add more reagent.

[0082] The second scenario is that the solid reagent is not completely dissolved. If it is not completely dissolved, the concentration detected by the detection module 105 will gradually increase and fall below the set threshold. At this time, the power pump 102 stops operating, waits for the set time for dissolution to continue, and then restarts the power pump 102. If the concentration detected by the detection module 105 still does not reach the set threshold and the concentration does not change, it is determined that too little solid reagent has been added, and the system alarms to remind the user to add solid reagent. If the set threshold is reached, the formal cleaning and disinfection procedure begins. If the concentration continues to increase and still does not reach the set threshold, the above process is repeated until the concentration remains constant or reaches the set threshold. The system sets the dissolution time for the solid reagent, which can be determined experimentally. By setting a preset time, infinite loop detection is avoided.

[0083] When the detection module 105 for detecting the concentration of the specific reagent solution has high accuracy, the following three methods are used for detection and control:

[0084] Optionally, Method 1 involves pre-setting the cleaning and / or disinfection cycle time. After turning on the power pump 102, the following steps are also included:

[0085] S310, Detection module 105 detects whether the concentration of the reagent solution reaches the preset value;

[0086] If yes, then the cycle time for cleaning and / or disinfection will begin to be counted until the preset cycle time is reached.

[0087] Optionally, after setting the cycle time in advance and turning on the power pump 102, the following steps are also included:

[0088] S320, Detection module 105 detects whether the concentration of the reagent solution has changed;

[0089] No, the cleaning and / or disinfection cycle time will be counted starting after the cleaning and disinfection procedure begins.

[0090] When the concentration of the reagent solution does not change, meaning the solid reagent is completely dissolved, and a high-precision conductivity sensor detects that the conductivity of the reagent solution has reached the set value, the cleaning and disinfection time is recorded. When the set cycle time is reached, the cleaning and disinfection program is considered to be over.

[0091] Method 3: Optionally, the detection module 105 detects whether the concentration of the reagent solution has reached a preset value;

[0092] S330. If the concentration of the detection reagent solution in the detection module 105 does not reach the preset value within the preset time, the power pump 102 will be turned off.

[0093] Returning to step S100, after being prompted or receiving an alarm, the user adds the solid reagent into the cleaning container 200 to form a reagent solution.

[0094] Within the preset time, which is theoretically the time it takes for the solid reagent to completely dissolve, if the concentration still does not reach the preset value, it means that too little solid reagent has been added, and therefore it is necessary to add more solid reagent.

[0095] In other embodiments, the number of cleaning and / or disinfection cycles can be preset. When the detection module 105 detects whether the concentration of the reagent solution meets the requirements, the cycle count for the cleaning and / or disinfection program begins to be recorded until the preset number of cycles is reached, at which point the cleaning and disinfection program ends. The specific steps for starting to count the cycle count are the same as those described above. The calculation of the cycle count is based on existing technology and will not be elaborated further. Since recording the cycle count requires the sensor to distinguish the transition between two cycles, it is less convenient than directly recording the cycle time.

[0096] Therefore, the functions of the detection module 105 include: first, detecting whether solid reagents have been added; second, detecting whether the amount of solid reagent added is sufficient (mainly referring to powder, granules, or multiple-addition blocks; if only one addition is needed, there is no need to detect whether the amount added is sufficient); and third, determining the start of the cleaning and disinfection procedure when the concentration of the reagent solution reaches the required level.

[0097] When the detection module 105 has high accuracy, as a preferred embodiment, the detection module 105 includes a high-accuracy sensor, which can be installed on the dialysate line 101 or the first connecting line 107, and can achieve the above three functions. Furthermore, installing the high-accuracy sensor on the first connecting line 107 results in faster detection feedback. Specifically, the high-accuracy sensor can be a high-precision conductivity sensor. As another preferred embodiment, the detection module 105 also includes, in addition to the high-accuracy sensor (specifically located on the dialysate line 101), a high-accuracy sensor (specifically located on the dialysate line 107). Figure 1 The sensor 1051, other than the sensor referred to by reference numeral 105, is a lower-precision conductivity sensor. This lower-precision conductivity sensor can only detect whether the conductivity of the reagent solution reaches a set threshold, which can be set. If the threshold is not reached, the lower-precision conductivity sensor transmits a zero signal. If the threshold is reached, it is considered that a solid reagent has been added.

[0098] Preferably, a higher-precision sensor is installed on the dialysate line 101. This higher-precision sensor, in addition to its function, can also be used to detect the dialysate concentration. A lower-precision sensor 1051 is installed on the first connecting line 107. The lower-precision sensor 1051 is used to detect whether solid reagent has been added, thus achieving the first function. The higher-precision sensor is used to detect whether the amount of solid reagent added is sufficient, that is, to detect whether the reagent concentration has reached a preset value. When the preset value is reached, the cleaning and disinfection procedure is initiated, thus achieving the latter two functions. Optionally, if the solid reagent is added in multiple batches, the cleaning and disinfection method further includes:

[0099] The low-precision sensor 1051 detects whether the concentration of the reagent solution is zero;

[0100] If yes, the program will determine that the user has not added solid reagent and return to step S100. After being prompted or alarmed, the user will add solid reagent into the cleaning container 200 to form a reagent solution.

[0101] No, then a high-precision sensor detects whether the amount of solid reagent added is sufficient, that is, whether the reagent concentration has reached the preset value;

[0102] When the preset value is reached, the cleaning and disinfection procedure is initiated; if the preset value is not reached and it has been confirmed that the solid reagent has been fully dissolved, the solid reagent is added again.

[0103] The cleaning and disinfecting solution is first detected by the lower-precision sensor 1051. Because the lower-precision sensor 1051 is located on the first connecting pipe 107, it is a long distance away from the higher-precision sensor located inside the dialysis machine. The cleaning and disinfecting solution needs a certain amount of time to flow between the two. This allows for faster detection and determination of whether the user needs to add the medication, avoiding the equipment from running idle, and timely reminders to the user to add the medication.

[0104] Optionally, if the solid reagent is for single use, the cleaning and disinfection method may also include:

[0105] The low-precision sensor 1051 detects whether the concentration of the reagent solution is zero;

[0106] If yes, the program will determine that the user has not added solid reagent and return to step S100. After being prompted or alarmed, the user will add solid reagent into the cleaning container 200 to form a reagent solution.

[0107] No, then the cleaning and / or disinfection cycle time will begin to be counted.

[0108] When adding solid reagents in a single batch, the amount of solid reagent to be added needs to be calculated in advance to ensure that the resulting reagent solution reaches the required concentration. The specific amount of solid reagent required to achieve the desired concentration can be verified through repeated experiments.

[0109] In one embodiment, the detection module 105 may include a lower precision sensor 1051, which is placed in the cleaning container 200 or on the suction rod 103, instead of being placed on the first connecting pipe 107, and can detect the concentration of the reagent solution more directly.

[0110] During the cleaning and disinfection process, the cleaning and disinfecting solution circulates in the dialysate tubing 101 of the dialysis machine that needs cleaning and disinfection. The circulation time is preset. If the detected concentration gradually increases over time, recording begins when the concentration detected by the sensor reaches the set concentration or when the detected concentration remains constant over time and is within the preset range. Alternatively, within a preset time range (e.g., 10 seconds to 1 minute), if the detected concentration of the cleaning and / or disinfecting solution remains constant and is within the preset range, recording begins. Furthermore, if the detected concentration remains constant over time and does not reach the preset value, the system stops the cleaning or disinfection program and prompts the user to add cleaning and disinfecting agents. Alternatively, within a preset time range (e.g., 10 seconds to 1 minute), if the detected concentration of the cleaning and / or disinfecting solution remains constant and does not reach the preset value, the system stops the cleaning or disinfection program. The concentration or concentration value described in this section can be pre-set by the conductivity value detected by the sensor, because there is a conversion relationship between the detection concentration and the conductivity value. Specifically, the detection concentration can be obtained by converting the conductivity value detected by the conductivity sensor and then processing the detection concentration, or the conductivity value detected by the conductivity sensor can be processed directly.

[0111] The dialysis apparatus 100 also includes a prompting module and a control system, which are communicatively connected. The prompting module is used to prompt the addition of solid reagents into the cleaning container 200. Before the solid reagents are added into the cleaning container 200 to form a reagent solution, the apparatus further includes:

[0112] S101. Start the control system and enter the cleaning and disinfection program;

[0113] S102, Control system control prompt module, prompting the user to put solid reagent into the cleaning container 200.

[0114] The specific control system is connected to the power pump 102 for communication and is used to control the power pump 102 to open or close. For example, after the control system starts for a preset time, it starts various programs according to the preset time to achieve automatic control.

[0115] In some embodiments, the prompting module is a display screen or an operation panel, with the display screen showing prompts to the user to add solid reagents. Alternatively, it can be an alarm that sounds to prompt the user to add the solid reagents. By setting up an operation panel, the user can confirm the corresponding cleaning and disinfection process, instructing the system to continue to the next step, or confirm the system's prompts to ensure that the user has performed the corresponding operations as instructed.

[0116] Furthermore, once the cleaning and disinfection process begins, the system will automatically display a prompt on the control panel, which the user then needs to confirm on the control panel.

[0117] Example 2

[0118] This embodiment also provides a method for cleaning and disinfecting a dialysis device, which is basically the same in structure as that in Embodiment 1. The same parts will not be described again. The difference is that the dialysis device 100 also includes a shell with an opening and a cover covering the opening. The cover is equipped with a motion sensor. The cleaning and disinfection method includes:

[0119] Open the lid and put the solid reagent into the cleaning container 200;

[0120] The solid reagent forms a reagent solution in the cleaning container 200, and the time when the lid is opened is taken as the start time of solid reagent dissolution.

[0121] The user opens the lid of the cleaning tank. A motion sensor is installed on the lid, such as a microswitch between the lid and the dialysis equipment housing. For example, one side of the lid has a rotating shaft, allowing the user to lift the other side of the lid, causing it to rotate around the shaft and open. In one embodiment, the microswitch is positioned between the bottom of the side where the lid is lifted and the dialysis equipment housing. It is positioned on the dialysis equipment housing corresponding to the lifted and closed side of the lid when the lid is closed. The microswitch detects the lid being closed, and when the lid is opened, the lid separates from the detection part of the microswitch, thus detecting that the lid is open. In another embodiment, the microswitch is positioned on the back side of the lid when it is open. The control system detects the open state and uses the time of lid opening as the start time of drug dissolution.

[0122] Of course, it takes time for the user to open the lid and add the reagent into the cleaning container 200. This time can be added as compensation when the control system records the data. Therefore, further, the solid reagent forms a reagent solution in the cleaning container 200, and the time after the lid is opened for a preset period is taken as the start time of solid reagent dissolution, where the preset period is the time added as compensation.

[0123] Example 3

[0124] This embodiment also provides a method for cleaning and disinfecting a dialysis device, which has a structure that is basically the same as that in Embodiments 1 and 2. The identical parts will not be described again. The difference is that the dialysis device 100 includes: a screw cap and a tightening action sensor on the suction rod 103; the cleaning and disinfection method includes:

[0125] Solid reagents are placed into cleaning container 200, where they form a reagent solution.

[0126] Tighten the suction rod 103 to seal the cleaning container 200 with the screw cap. The tightening action sensor detects that the suction rod 103 is rotated. The rotation state of the suction rod 103 detected by the tightening action sensor is used as the start time of solid reagent dissolution.

[0127] The user puts the cleaning and disinfecting agent into the cleaning container 200 and puts the suction rod 103 back into the cleaning container 200. A tightening action sensor is set above the suction rod 103. When the tightening action sensor detects that the suction rod 103 is tightened, that is, the cleaning container 200 is sealed, the tightening state detected by the tightening action sensor is used as the start time of the dissolution time.

[0128] Furthermore, the suction rod 103 is screwed on to seal the cleaning container 200. The tightening action sensor detects that the suction rod 103 is tightened, and the time preceding the preset time of the tightening state detected by the sensor is taken as the start time for solid reagent dissolution. During tightening, the user has already added the reagent to the cleaning container 200, causing a delay in the start time; therefore, the start time is taken as before the preset time. However, this time is generally negligible because, assuming the reagent is dissolved, the dissolution time is longer than the set dissolution time and does not affect subsequent cleaning and disinfection procedures.

[0129] As a preferred embodiment, the dialysis device 100 also includes a housing with an opening and a lid covering the opening. The lid is opened, and solid reagents are placed into the cleaning container 200. The suction rod 103 is screwed on to seal the cleaning container 200. A tightening action sensor detects that the suction rod 103 is tightened, and the tightening state detected by the tightening action sensor is used as the start time for solid reagent dissolution. Because the time between opening the lid of the cleaning container 200 and the user placing the reagent into the cleaning container 200 requires time compensation, using the tightening state detected by the tightening action sensor as the start time for dissolution would delay the start time. Therefore, the preset time before the suction rod 103 is tightened is used as the start time. However, user operation is uncontrollable, and time compensation may not be able to compensate for this time. Accuracy can be ensured by repeatedly testing the time between opening the lid and placing the solid reagent into the cleaning container 200.

[0130] For example, the tightening action sensor can be a photoelectric sensor, which is mounted on the suction rod 103. A baffle is provided on the cleaning container 200 or other components of the dialysis device 100. When the suction rod 103 is tightened, the presence or absence of a baffle blocking the photoelectric sensor determines whether the suction rod 103 is tightened. Other types of sensors can also be used for the tightening action sensor, and there is no limitation.

[0131] Example 4

[0132] This embodiment also provides a dialysis device 100, which has a structure that is basically the same as that in embodiments one to three. The same parts will not be described again. The differences are as follows: Figure 4As shown, the dialysis device 100 also includes a degassing module 106, which can be described in accordance with existing technology and will not be elaborated further. The dialysis device 100 also includes a second connecting pipe 108, through which the degassing module 106 and the cleaning container 200 are selectively connected. Specifically, it also includes a valve (not shown in the figure) located on the second connecting pipe 108. One end of the second connecting pipe 108 is connected to the degassing module 106, and the other end can be connected to the cleaning container 200. This embodiment also provides a dialysis device cleaning and disinfection method, which includes the following steps before step S100 or between step S100 and step S200:

[0133] S400 connects the degassing module 106 and the cleaning container 200. Gas generated during the dissolution of the solid reagent is discharged through the degassing module 106. When the solid reagent is an effervescent agent, the cleaning container 200 is connected to the degassing module 106 via the second connecting pipe 108 to remove gas generated during effervescence. Degassing is achieved using the degassing module 106 in the existing dialysis equipment 100, which has a simple structure and is easy to operate.

[0134] The second connecting pipe 108 is connected to the top of the cleaning container 200 on one side to ensure that the generated gas is discharged by the degassing module 106 as much as possible.

[0135] If the solid reagent does not produce gas, degassing is not required during the dissolution process. This situation corresponds to... Figure 1 Examples of implementations.

[0136] However, if it does not have an effervescent function and does not produce gas, the dissolution time is relatively long. Therefore, it is preferable to have an effervescent function, and at the same time, a degassing module 106 is required for degassing.

[0137] If a solid reagent with effervescent components is added to the cleaning container 200, and the solid reagent has completely dissolved and no more gas is produced, then the cleaning container 200 can be sealed. This is because the gas produced during the dissolution process of the solid reagent was already released before sealing, so this situation can also be handled accordingly. Figure 1 Examples of implementations.

[0138] However, preferably, the cleaning container 200 is connected to the degassing module 106, which facilitates filling the cleaning container 200 through the water inlet.

[0139] The valve on the second connecting pipe 108 shall be opened in at least the following two situations:

[0140] First, solid reagents are added, and the solid reagents dissolve and effervescent during the process, followed by sealing the cleaning container with the lid. This process can be detected by a motion sensor on the lid when it is closed. Further, when the tightening motion sensor detects a tightened state, the system controls the opening of the valve on the degassing pipeline connecting the cleaning container 200 to the degassing module 106. The cleaning and disinfecting agent effervesces and dissolves in the added cleaning container 200. The dissolution time is preset, and the system starts a countdown. When the preset time is reached, the cleaning and disinfection program starts, and the power pump 102 starts to send the dissolved disinfectant into the dialysate pipeline 101, initiating the corresponding cleaning and disinfection procedure.

[0141] As a preferred option, when the cleaning or disinfection process begins, the power pump 102 starts to send the dissolved disinfectant into the water system, while the valve on the degassing pipeline is closed at the same time.

[0142] Secondly, during the cleaning or disinfection process, when the second connecting pipeline 108 needs to be cleaned and disinfected. Further, the degassing module 106 includes a degassing pump, which can provide negative pressure to the second connecting pipeline 108. When cleaning and / or disinfecting the dialysate pipeline 101, the valve is opened according to the set cleaning and / or disinfection program to clean and / or disinfect the second connecting pipeline 108. During the cleaning and disinfection process, the cleaning program of the second connecting pipeline 108, which connects the cleaning container 200 and the degassing module 106, is set in the system's preset cleaning and disinfection control program. The valve in the degassing pipeline is opened or closed according to the set cleaning and / or disinfection program to ensure effective cleaning of the pipeline. As one implementation, when the second connecting pipeline 108 is being cleaned, the degassing pump on the degassing module 106 provides power, that is, the degassing module 106 applies negative pressure to the degassing pipeline. At this time, the valve on the degassing pipeline is opened, allowing the cleaning and disinfection solution in the cleaning container 200 to flow into the second connecting pipeline 108. In addition to cleaning and disinfecting with cleaning and disinfecting agents, high-temperature liquid disinfection is also required. The above steps must also be performed when using high-temperature liquid disinfection.

[0143] Example 5

[0144] This embodiment also provides a dialysis device 100, which has a structure that is basically the same as that in embodiments one to four. The same parts will not be described again. The differences are as follows: Figure 5 As shown, the dialysis apparatus 100 also includes an accelerator pump 104 and a third connecting pipe 109. Two cleaning containers 200 are provided, connected via the third connecting pipe 109, with the accelerator pump 104 mounted on the third connecting pipe 109. The addition of the third connecting pipe 109 allows flow in both cleaning containers 200, accelerating the dissolution rate of solid reagents. Two suction rods 103 are provided, and two cleaning containers 200 are provided; the two suction rods 103 are respectively inserted into the two cleaning containers 200.

[0145] This embodiment also provides a method for cleaning and disinfecting dialysis equipment, such as... Figure 3 As shown, before turning on the power pump 102, the following are also included:

[0146] S500, turn on the accelerator pump 104 to circulate the liquid in the two cleaning containers 200 and accelerate the dissolution of the solid reagent;

[0147] S600: After a preset time has elapsed since the solid reagent was placed into the cleaning container 200, turn off the acceleration pump 104.

[0148] When the time after adding the solid reagent reaches the preset time, the power pump 102 is turned on, and the acceleration pump 104 stops running at the same time, which speeds up the dissolution rate of the solid reagent and thus improves the cleaning and disinfection efficiency.

[0149] Furthermore, the start time of the accelerator pump 104 can be taken as the time it takes to close or tighten the cover.

[0150] Example 6

[0151] This embodiment also provides a dialysis device 100, which has a structure that is basically the same as that in embodiments one to five. The same parts will not be described again. The differences are as follows: Figure 6 As shown, the cleaning container 200 is provided with two suction rods 103 inserted into it, which further simplifies the structure.

[0152] Furthermore, the dialysis machine is equipped with a control system, which controls the opening and closing of all pumps and valves, the detection data from sensors, and the time control.

[0153] Example 7

[0154] This embodiment also provides a dialysis device 100, which has a structure basically the same as that in embodiments one to five. The identical parts will not be described again. The difference lies in that, before starting the cleaning and / or disinfection procedure, the dialysis device 100 provides a prompt, and if it has an operating screen or touchscreen, prompts for the addition of solid reagents. The type of solid reagent is indicated differently depending on the cleaning or disinfection procedure. After the user adds the reagent, they click to confirm, and the time of confirmation is used as the start time for the preset dissolution time of the solid reagent.

[0155] In another implementation, the dialysis device 100 is equipped with a lid. When the user adds solid reagents, the lid needs to be closed. The motion sensor on the lid can detect the open / closed state of the lid. The cleaning and disinfection method also includes:

[0156] After adding the solid reagent into the cleaning container 200, close the lid. The time it takes to close the lid is taken as the start time of the solid reagent dissolution time.

[0157] When the user starts cleaning and / or disinfection, the control system determines whether the solid reagent dissolution time has reached the preset dissolution time.

[0158] If yes, then begin the cleaning and / or disinfection process;

[0159] No, wait until the preset dissolution time is reached before starting the cleaning and / or disinfection process.

[0160] After the user adds the reagent and closes the lid, the system automatically records the time when the lid is closed. When the user clicks the button to start the cleaning and disinfection program, the system uses the time when the lid is closed as the starting point of the dissolution time. If the dissolution time has been exceeded at this time, the cleaning or disinfection program will start in a loop. If the set dissolution time has not been reached, the system will wait until the dissolution time is reached before starting the cleaning and disinfection program.

[0161] Similarly, as another implementation, when the suction rod 103 is equipped with a screw cap and a tightening action sensor, the user needs to close the screw cap when adding solid reagents. The tightening action sensor can detect the tightening state of the suction rod 103, thereby detecting the tightening state of the screw cap.

[0162] Cleaning and disinfection methods also include:

[0163] After the solid reagent is put into the cleaning container 200, tighten the suction rod 103. The time when the cap is tightened is taken as the start time of the solid reagent dissolution time.

[0164] When the user starts cleaning and / or disinfection, the control system determines whether the solid reagent dissolution time has reached the preset dissolution time.

[0165] If yes, then begin the cleaning and / or disinfection process;

[0166] No, wait until the preset dissolution time is reached before starting the cleaning and / or disinfection process.

[0167] After the user has finished adding the fixed reagent and tightened the suction rod 103, the system automatically records the time when the cap is tightened. When the user clicks the button to start the cleaning and disinfection program, the system uses the time when the cap is tightened as the starting point of the dissolution time. If the dissolution time has been exceeded at this time, the cleaning or disinfection program will start in a loop. If the set dissolution time has not been reached, the system will wait until the dissolution time is reached before starting the cleaning and disinfection program.

[0168] Furthermore, when a user begins cleaning and / or disinfection, they do so by clicking the button to start the cleaning and disinfection program.

[0169] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art can make other variations or modifications based on the above description. It is neither necessary nor possible to exhaustively describe all embodiments here.
