Description

Technical Field

[0001] The present invention relates to a waste liquid collection and treatment system and a waste liquid treatment method for docking with a waste liquid collection device for collecting and treating waste liquid materials generated in a medical process. Background Art

[0002] During certain surgical procedures, liquid, semi-solid, and solid wastes are inevitably generated. These include bodily fluids, such as blood, and perfusion solutions introduced to the surgical site during surgery. Solid and semi-solid wastes also include tissue fragments and small pieces of surgical material that may remain in the body. Ideally, waste should be collected as soon as it is generated so that it does not contaminate the surgical site or become a biohazard in the operating room or other locations where the procedure is performed.

[0003] In the prior art, there are various waste fluid collection and treatment systems that medical staff use to collect waste fluids generated during or after surgery. These systems primarily utilize a vacuum source to generate suction, drawing waste fluids from the surgical site into a specific collection container. Specifically, upon activation, the vacuum source generates suction that reaches the surgical site, drawing the waste fluids through the tubing in contact with the surgical site and into a specific collection container.

[0004] In the prior art, in the medical waste liquid collection and treatment system, waste liquid materials are collected in a waste liquid collection container connected to a vacuum source. The waste liquid collection container is generally mounted on a portable trolley with wheels for easy movement and transportation. Generally speaking, during the suction process, when the storage volume of the waste liquid collection container reaches a predetermined volume, the waste liquid collection container needs to be emptied. The early prior art practice is to push the waste liquid collection device to the docking station and empty and clean it. After the waste liquid collection unit is docked to the docking station, it begins to be emptied. Once emptied, the waste liquid collection container is cleaned by the cleaning system through disinfection and cleaning. In a series of medical processes, each process requires emptying. The frequent operation of pushing the waste liquid collection device to the docking station each time brings a lot of inconvenience to the user and affects the progress of medical treatment. Therefore, in response to this technical defect, a transfer device specifically used to transport waste liquid from waste liquid collection equipment to a docking station has been developed. That is, a docking device specifically used to transport waste liquid from waste liquid collection equipment. This device usually includes two connectors that dock with two connectors of the waste liquid collection equipment to form a liquid path connection. One liquid path is used to transfer the waste liquid from the waste liquid collection equipment to the docking device, and the other liquid path is used to clean the waste liquid collection container of the waste liquid collection equipment. In the prior art, after the docking device extracts the waste liquid from the waste liquid collection equipment, the waste liquid needs to be sent to a treatment station for disinfection treatment. The waste liquid can only be discharged after disinfection. Therefore, when using this device, an additional disinfection station is required to cooperate in order to complete the treatment and discharge of the waste liquid. Summary of the Invention

[0005] The technical problem to be solved by the embodiments of the present invention is to provide a waste liquid collection and treatment system that can automatically align and complete docking during the docking process. Before emptying the waste liquid in the waste liquid collection equipment docked with it, the docking equipment and the waste liquid collection equipment can cooperate to disinfect the waste liquid.

[0064] See also Figure 2 and Figure 5 After the waste liquid collection device 100 and the docking device 200 are docked, the waste liquid in the waste liquid collection device 100 is emptied through the docking device 200. In the embodiment of the present invention, after the docking device 200 and the waste liquid collection device 100 are docked, the waste liquid can be disinfected before being emptied from the waste liquid collection device 100. Figure 5 As shown, the waste liquid collection and treatment system 10 includes a waste liquid collection device 100 and a docking device 200, which is used to collect waste liquid generated during medical procedures.

[0065] The waste liquid collection device 100 includes: a waste liquid collection container 109, which is connected to the internal or external negative pressure source 461 and is used to store waste liquid generated during medical procedures; a collection end connector 312, which is connected to the waste liquid collection container 109 and connected to the suction device for introducing waste liquid generated during medical procedures, and the collection end connector 312 and the consumable box 300 are connected via a collection liquid path 450; a liquid inlet connector 112, which is connected to the liquid inlet of the waste liquid collection container 109 and is used to dock with the liquid feed connector 212 of the docking device 200 to form an input liquid path 410 for injecting liquid into the waste liquid collection container 109 of the waste liquid collection device 100; a liquid discharge connector 114, which is connected to the waste liquid collection container 109 and is used to dock with the suction connector 301 of the docking device 200 to form a liquid discharge path 420 for extracting liquid from the waste liquid collection container 109. The waste liquid collection container 109 is connected to a negative pressure source 461 via a negative pressure gas line 460 . The negative pressure source 461 may be disposed within the waste liquid collection device 100 or may be an external negative pressure source.

[0066] like Figure 5 As shown, the docking device 200 is used in the waste liquid collection and treatment system 10 to discharge the waste liquid generated during the medical process collected by the waste liquid collection device 100 in the waste liquid treatment system 10. The docking device 200 includes:

[0067] A liquid feed connector 214 is used to connect with the liquid inlet connector 114 of the waste liquid collection device 100 to form an input liquid path 410 for injecting liquid into the waste liquid collection container 109 of the waste liquid collection device 100;

[0068] The suction connector 212 is used to connect with the discharge connector 112 of the waste liquid collection device 100 to form a discharge liquid path 420 for extracting the liquid in the waste liquid collection container 109;

[0069] A liquid discharge pump 421 connected to the suction connector 212 and used to suck the liquid in the waste liquid collection container 109;

[0070] a liquid adding pipeline 440 , communicating with the input liquid path 410 to add disinfectant or cleaning liquid to the input liquid path 410 ;

[0071] The switching pipeline 430 is connected to the input liquid circuit 410 at one end and the discharge liquid circuit 420 at the other end, so that the input liquid circuit 410 and the discharge liquid circuit 420 can be connected to each other or isolated from each other; when the input liquid circuit 410 and the discharge liquid circuit 420 are isolated from each other, the discharge liquid circuit 420 discharges the waste liquid sucked by the discharge pump 421 through the discharge port 423 provided in the discharge liquid circuit 420; when the input liquid circuit 410 and the discharge liquid circuit 420 are connected to each other, the discharge port 423 is closed, and the input liquid circuit 410 and the discharge liquid circuit 420 form a circulation path for liquid circulation, and the discharge pump 421 sucks the liquid in the waste liquid collection container 109 through the suction joint 212 and injects the sucked liquid into the waste liquid collection container 109 through the liquid feeding joint 214. At the same time, the disinfectant added through the liquid adding pipeline 440 also enters the waste liquid collection container 109 through the input liquid circuit 410, and the liquid circulation disinfection operation is performed together according to the predetermined disinfection procedure.

[0072] Specifically, the switching pipeline 430 is provided with a switching valve 431 for shutting off or connecting the switching pipeline 430 so as to achieve the purpose of interconnecting or isolating the input liquid path 410 and the discharge liquid path 420. Correspondingly, a discharge control valve 422 is also provided between the discharge pump 421 and the discharge port 423 for closing or opening the discharge port 423. Of course, the switching valve 431 and the discharge control valve 422 can be combined into a three-way valve to realize the shutoff and connection of different pipelines. The discharge port 423 can be directly a hose connector connected to the discharge channel, or it can be a connector that can be connected to a hose, for example Figure 4 The drain connection 208 is shown as a drain that can be drained through a drain port 423 connected to an additional drain pipe.

[0073] Combine Figure 5 and Figure 6 , Figure 6 for Figure 5The circuit control schematic diagram of the waste liquid collection and treatment system 10 shown in the figure shows that the docking device 200 is also provided with a control module 500 connected to the switching valve 422 and the discharge control valve 432 respectively, for controlling the switching valve 422 and the discharge control valve 432. The control module 500 can also be used to control the duration of the disinfection program, and can change and operate the disinfection operation and related parameters by inputting a period. The control module 500 can also control other electrical components and programs in the docking device 200, such as the discharge pump 421, the air pump 473, the pneumatic control valve 474, etc. The control module 500 can also establish an electrical connection with the waste liquid collection device 100 through the first electrical signal connector on the docking device 200 to control the circuits and programs in the waste liquid collection device 100. Specifically, the docking device 200 includes a first electrical signal connector, and the waste liquid collection device 100 includes a second electrical signal connector, and the first electrical signal connector and the second electrical signal connector are electrically connected. The signal connection between the docking device 200 and the waste liquid collection device 100 can also be a wireless connection, which can be achieved by infrared, WiFi, Bluetooth, etc. In addition, the control module 500 can be set in the docking device 200 as well as in the waste liquid collection device 100.

[0074] In addition, the waste liquid collection and treatment system 10 may also be provided with a first liquid adding container 441, which is connected to the liquid adding pipeline 440, for storing disinfectant and adding disinfectant to the input liquid circuit 410 through the liquid adding pipeline 440. In order to achieve accurate addition of disinfectant, a first liquid adding pump 443 may also be provided. The first liquid adding pump 443 is respectively connected to the first liquid adding container 441 and the liquid adding pipeline 440 to pump the disinfectant in the first liquid adding container 441 into the liquid adding pipeline 440. The first liquid adding pump 443 can accurately control the amount of disinfectant added, thereby achieving accurate control of waste liquid disinfection. In this embodiment, the first liquid adding container 441 and the first liquid adding pump 443 can be used in conjunction with the comparison device 200 as external devices, that is, they can be used in conjunction with the interface provided on the liquid adding pipeline 440, such as Figure 4 The liquid adding interface 207 is shown. Optionally, the first liquid adding container 441 and the first liquid adding pump 443 are both provided in the docking device 200, and the first liquid adding container 441 and the first liquid adding pump 443 are part of the docking device 200. The docking device 200 is further provided with a first check valve 445, which is provided in the liquid adding pipeline 440 to prevent the liquid in the input liquid path 410 from flowing back.

[0075] In the embodiment of the present invention, after the docking device 200 and the waste liquid collection device 100 are docked, the waste liquid can be disinfected before being drained from the waste liquid collection device 100. The principle is as follows:

[0076] After docking device 200 and waste liquid collection device 100 are docked, if disinfection of the waste liquid in waste liquid collection device 100 is required, the operator selects to execute a disinfection procedure through docking control panel 206 of docking device 200 or collection control panel 103 of waste liquid collection device 100. After the operator triggers the disinfection procedure, control module 500 opens switching valve 422 and closes drain control valve 432, switching line 430 to open and connect input liquid path 410 and drain liquid path 420, while closing drain port 423. Input liquid path 410 and drain liquid path 420 form a circulation path for liquid circulation. The drainage pump 423 is activated. The drainage pump 423 sucks the liquid in the waste liquid collection container 109 through the suction connector 212 and injects the sucked liquid into the waste liquid collection container 109 through the liquid feeding connector 214. At the same time, the control module 500 controls the first liquid adding pump 443 to add a predetermined amount of disinfectant to the input liquid path 410 through the liquid adding pipeline 440 at a preset flow rate based on the amount of waste liquid in the waste liquid collection container 109. The disinfectant is injected into the waste liquid collection container 109 together with the waste liquid entering the input liquid path 410, and the liquid circulation disinfection operation is performed according to the predetermined disinfection program. The liquid circulation can ensure that the disinfectant and waste liquid are fully mixed, thereby enhancing the reaction effect between the disinfectant and waste liquid. The predetermined disinfection program can be pre-set in the system program based on factors such as the type of surgery, amount of waste fluid, type of disinfectant, etc. The operator can execute the disinfection program after setting various factors. For example, for a specific type of surgery and a specific amount of waste fluid, the disinfection cycle can be circulated for 15 minutes, or circulated 15 times and then left to stand for half an hour. These can be set and changed according to actual surgical needs and medical facility requirements, and will not be elaborated here.

[0077] After the disinfection process is completed, the drainage operation is performed. The principle is as follows:

[0078] The operator selects to execute the drain operation via the docking control panel 206 of the docking device 200 or the collection control panel 103 of the waste liquid collection device 100. After the operator triggers the drain procedure, the control module 500 closes the switching valve 422 and opens the drain control valve 432. The switching pipeline 430 closes and disconnects the input liquid path 410 and the discharge liquid path 420. Simultaneously, the discharge port 423 is opened, interrupting the circulation path formed by the input liquid path 410 and the discharge liquid path 420 for liquid circulation. The drain pump 423 is activated, sucking the liquid from the waste liquid collection container 109 through the suction connector 212 and discharging the disinfected waste liquid through the discharge port 423.

[0079] See also Figure 7 , Figure 7Schematic diagram of the connection principle of the second embodiment of the waste liquid collection and treatment system provided by the present invention. In the embodiment of the present invention, the liquid supply connector 214 is also used to provide a cleaning function for the waste liquid collection device 21, or in other words, in the embodiment of the present invention, the docking device 22 in the waste liquid collection and treatment system 20 cooperates with the waste liquid collection device 21 to disinfect the waste liquid before emptying the waste liquid in the waste liquid collection device 21. The processing structure partially reuses the flushing liquid path 4101 currently used to flush the waste liquid collection device 21 to form an input liquid path 4101 for circulating disinfection. Since the flushing liquid path 4101 is a commonly used technology in this field, the reuse of the flushing liquid path 4101 does not require a separate input liquid path for waste liquid circulation, thereby saving space and cost of the equipment. However, under certain requirements, an input liquid path can also be added separately. If the aperture of the flushing nozzle connected to the flushing liquid path 4101 is small, in order to prevent the flushing nozzle from being blocked, the flushing nozzle is not used as the port for waste liquid to enter the waste liquid collection container 1091. At this time, a separate port for entering waste liquid needs to be provided on the waste liquid collection container 1091, see Figure 7 As shown, the input liquid circuit 4101 is connected to a first input branch 411 and a second input branch 412, wherein the first input branch 411 is provided with a first branch control valve 414, and the first branch control valve 414 is used to control the shutoff and connection of the first input branch 411, and the second input branch 412 is provided with a second branch control valve 415, and the second branch control valve 415 is used to control the shutoff and connection of the first input branch 411.

[0080] Figure 7 The docking device 22 shown has Figure 5 In addition to the components shown, it also includes a tap water inlet 448 and a tap water control valve 447 that controls whether tap water can enter the liquid adding pipeline 4401. Accordingly, the waste liquid collection and treatment system 20 is also provided with a second liquid adding container 442 for storing cleaning liquid and adding cleaning liquid to the flushing liquid circuit 4101 through the liquid adding pipeline 4401. In order to achieve accurate addition of cleaning liquid, a second liquid adding pump 444 can also be provided, which is connected to the second liquid adding container 442 and the liquid adding pipeline 4401, respectively, and is used to pump the cleaning liquid in the second liquid adding container 442 into the input liquid circuit, that is, the flushing liquid circuit 4101. The second liquid adding pump 443 can accurately control the amount of cleaning liquid added, thereby achieving accurate control of the flushing of the waste liquid collection container 1091. In this embodiment, the second liquid adding container 442 and the second liquid adding pump 444 can be used in conjunction with the comparison device 22 as external devices, that is, they are used in conjunction with the interface set in the liquid adding pipeline 4401, such as Figure 4The liquid adding interface 207 is shown. Optionally, the second liquid adding container 442 and the second liquid adding pump 444 are both provided in the docking device 22, i.e., the second liquid adding container 442 and the second liquid adding pump 444 are part of the docking device 22. The docking device 22 is also provided with a second check valve 446, which is provided in the liquid adding pipeline 4401 to prevent the liquid in the first liquid adding container 441 and the second liquid adding container 442 from flowing back toward the tap water interface 448 and contaminating the water source.

[0081] In the embodiment of the present invention, after the docking device 22 and the waste liquid collecting device 21 are docked, the waste liquid can be disinfected before the waste liquid in the waste liquid collecting device 21 is emptied. Figure 7 and Figure 8 , the principle is as follows:

[0082] After docking device 22 and waste liquid collection device 21 are docked, if disinfection of the waste liquid in waste liquid collection device 21 is desired, the operator selects to execute a disinfection procedure through the docking control panel of docking device 22 or the collection control panel of waste liquid collection device 21. After the operator triggers the disinfection procedure, control module 501 opens switching valve 422 and closes drain control valve 432. Switching line 430 opens and connects input liquid path 4101 and drain liquid path 420, while closing drain port 423. Input liquid path 4101 and drain liquid path 420 form a circulation path for liquid circulation. The drainage pump 423 is activated. It draws liquid from the waste liquid collection container 1091 through the suction connector 212 and injects the drawn liquid into the waste liquid collection container 1091 through the liquid feed connector 214. Simultaneously, the control module 501 controls the first liquid addition pump 443 to add a predetermined amount of disinfectant to the input liquid path 4101 via the liquid addition line 440 at a preset flow rate based on the amount of waste liquid in the waste liquid collection container 1091. Because the flushing holes in the flushing head are typically very small, to prevent blockage, after the disinfection procedure is initiated, the control module 501 opens the first branch control valve 414 to connect the first input branch 411 and closes the second branch control valve 415 to disconnect the second input branch 412. The disinfectant and waste liquid entering the input liquid path 4101 are then injected into the waste liquid collection container 1091 through the first input branch 411, and the liquid circulation disinfection operation is performed according to the predetermined disinfection procedure. Liquid circulation ensures thorough mixing of the disinfectant and waste liquid, enhancing the reaction between the disinfectant and waste liquid. The predetermined disinfection program can be pre-set in the system program based on factors such as the type of surgery, amount of waste fluid, type of disinfectant, etc. The operator can execute the disinfection program after setting various factors. For example, for a specific type of surgery and a specific amount of waste fluid, the disinfection cycle can be circulated for 15 minutes, or circulated 15 times and then left to stand for half an hour. These can be set and changed according to actual surgical needs and medical facility requirements, and will not be elaborated here.

[0083] After the disinfection process is completed, the drainage operation is performed. The principle is as follows:

[0084] The operator selects to execute the drain operation through the docking control panel of the docking device 22 or the collection control panel of the waste liquid collection device 21. After the operator triggers the drain procedure, the control module 501 closes the switching valve 422 and opens the drain control valve 432. The switching pipeline 430 closes and shuts off the input liquid path 4101 and the discharge liquid path 420. Simultaneously, the discharge port 423 is opened, interrupting the circulation path formed by the input liquid path 4101 and the discharge liquid path 420 for liquid circulation. The drain pump 423 is activated, and the drain pump 423 sucks the liquid in the waste liquid collection container 1091 through the suction connector 212 and discharges the disinfected waste liquid through the discharge port 423.

[0085] After the drainage operation is performed, the waste liquid collection container 1091 is flushed. The principle is as follows:

[0086] The operator selects to perform a flushing operation through the docking control panel of the docking device 22 or the collection control panel of the waste liquid collection device 21. At this time, the input liquid circuit 4101 (i.e., the flushing liquid circuit 4101) and the discharge liquid circuit 420 are disconnected. The control module 501 opens the tap water control valve 447 to allow tap water to enter the liquid addition pipeline. Based on the tap water flow rate, the second liquid addition pump 444 is controlled according to the preset flushing settings to pump the cleaning liquid in the second liquid addition container 444 into the liquid addition pipeline 4401. The tap water and cleaning liquid pass through the input liquid circuit 4101. After the flushing procedure is initiated, the control module 501 opens the second branch control valve 415 to connect the second input branch 412 and closes the first branch control valve 414 to disconnect the first input branch 411. The cleaning liquid and tap water entering the input liquid circuit 4101 flush the waste liquid collection container 1091 through the second input branch 412 and the flushing terminal connected thereto. After flushing is completed, the liquid in the waste liquid collection container 1091 can be drained.

[0087] See also Figures 9-11 , Figure 9 This is a schematic diagram of the connection principle of the third embodiment of the waste liquid collection and treatment system provided by the present invention. Figure 10 for Figure 9 Circuit control diagram of the waste liquid collection and treatment system, Figure 11 for Figure 9The schematic diagram of the structure of the waste liquid collection container of the waste liquid collection and treatment system shown in FIG. In this embodiment of the present invention, the waste liquid collection device 31 of the waste liquid collection and treatment system 30 is provided with a waste liquid collection container 1092. The waste liquid collection container 1092 includes a first inner cavity 116 and a second inner cavity 117 that can be connected and isolated from each other. The first inner cavity 116 is provided with a first negative pressure interface 911, a collection inlet 912, and a first flushing inlet 913; the second inner cavity 117 is provided with a second liquid inlet 917 and a liquid discharge outlet 916.

[0088] The negative pressure source 461 is connected to the first negative pressure interface 911 via the negative pressure air circuit 460 to provide negative pressure to the first inner cavity 116 and the second inner cavity 117 of the waste liquid collection container 1092. The collection end connector 312 is connected to the collection inlet 912 to draw waste liquid generated during surgery into the waste liquid collection container 1092 for storage. The first flushing inlet 913 is connected to the input liquid circuit 4102 so that during the flushing process, the cleaning fluid and tap water in the input liquid circuit 4102 can enter the first inner cavity 116 through the third input branch 413 connected to the first flushing inlet 913 and flush the waste liquid collection container 1092 through the flushing end. If necessary, in other embodiments, a first liquid inlet may be provided on the first inner cavity 116 to allow the disinfectant and waste liquid in the input liquid circuit 4102 to be introduced into the first inner cavity 116 during the disinfection process, or the first flushing inlet 913 may be directly used as the first liquid inlet. However, since cyclic disinfection only requires the formation of a circulation loop, in order to increase fluidity and reduce damage to the flushing tip, in this embodiment, during the disinfection phase, only the waste liquid and disinfectant are circulated through the second inner cavity 117 without entering the first inner cavity 116. Based on this, the second inner cavity 117 is provided with a second liquid inlet 917, which is connected to the first input branch 411 so that during the disinfection phase, the mixed liquid of disinfectant and waste liquid can enter the second inner cavity 117. At this time, the input liquid circuit 4102 is connected to the first input branch 411 and the third input branch 413 respectively. The first input branch 411 is connected to the second liquid inlet 917, and the third input branch 413 is connected to the first flushing inlet 913. The first branch control valve 414 and the third branch control valve 416 are respectively provided on the first input branch 411 and the third input branch 413. In other embodiments, a second flushing inlet can be provided on the second cavity 117. Figure 7 The second input branch 412 is shown connected for purging the second lumen 117 .

[0089] Furthermore, the second cavity 117 can be connected to the negative pressure output hole 914 on the first cavity 116 via a short tube through the second negative pressure interface 924 to provide negative pressure for the second cavity 117 .

[0090] That is, a third branch control valve 416 is provided between the liquid inlet connector 114 and the first flushing inlet 913 of the first inner cavity 116; a first branch control valve 414 is provided between the liquid inlet connector 114 and the liquid inlet 117 of the second inner cavity 117; when the liquid feeding connector 214 and the suction connector 212 are connected, the third branch control valve 416 is closed to disconnect the pipeline between the liquid inlet connector 114 and the first flushing inlet 913 of the first inner cavity 116, and at the same time, the first branch control valve 414 is opened to open the pipeline between the liquid inlet connector 114 and the liquid inlet 917 of the second inner cavity 117 to form a circulation passage.

[0091] At the same time, in order to prepare disinfectant and cleaning liquid according to the amount of waste liquid, the waste liquid collection container is also provided with a liquid level detector. Figure 10 and Figure 11 In the illustrated embodiment, the first cavity 116 and the second cavity 117 are respectively provided with a first measuring hole 915 and a second measuring hole 918 . The first measuring hole 915 is used to insert a liquid level measurer 921 , and the second measuring hole 918 is used to insert a second liquid level measurer 922 .

[0092] Figure 10 As shown, the waste liquid collection and treatment system 30 includes a control module 502, which can be set in the waste liquid collection device 31 or in the docking device 32, and is used to control the switching pipeline 430 to shut off or connect the input liquid path 4102 and the discharge liquid path 420, and control the discharge liquid path 420 to discharge the waste liquid in the waste liquid collection container 1902 sucked by the discharge pump 421 through the liquid discharge port 423 set in the discharge liquid path, or control the circulation path to perform liquid circulation disinfection operation according to a predetermined disinfection procedure.

[0093] In the embodiment of the present invention, after the docking device 32 and the waste liquid collecting device 31 are docked, the waste liquid can be disinfected before the waste liquid in the waste liquid collecting device 31 is emptied. Figure 9 and Figure 10 , the principle is as follows:

[0094] After docking device 32 and waste liquid collection device 31 are docked, if disinfection of the waste liquid in waste liquid collection device 31 is desired, the operator selects to execute a disinfection procedure through the docking control panel of docking device 32 or the collection control panel of waste liquid collection device 31. After the operator triggers the disinfection procedure, control module 502 opens switching valve 422 and closes drain control valve 432. Switching line 430 opens and connects input liquid path 4102 and drain liquid path 420, while closing drain port 423. Input liquid path 4102 and drain liquid path 420 form a circulation path for liquid circulation. The drainage pump 423 is activated. The drainage pump 423 draws the liquid from the second cavity 117 of the waste liquid collection container 1092 through the suction connector 212 and injects the drawn liquid into the second cavity 117 of the waste liquid collection container 1092 through the liquid feed connector 214. Simultaneously, the control module 502 controls the first liquid addition pump 443 to add a predetermined amount of disinfectant to the input liquid path 4102 through the liquid addition pipeline 440 at a preset flow rate based on the amount of waste liquid in the waste liquid collection container 1092. Since the flushing hole of the flushing terminal is generally very small, to prevent blockage of the flushing hole, after the disinfection procedure is initiated, the control module 502 opens the first branch control valve 414 to connect the first input branch 411 and closes the third branch control valve 416 to disconnect the third input branch 413. The disinfectant and waste liquid entering the input liquid circuit 4102 are injected into the second inner cavity 117 through the first input branch 411 without passing through the first inner cavity 116, and the liquid circulation disinfection operation is carried out according to the predetermined disinfection program. At this time, the first inner cavity 116 and the second inner cavity 117 can be in an isolated state. Liquid circulation can increase the thorough mixing of the disinfectant and waste liquid and enhance the reaction effect of the disinfectant and waste liquid. The predetermined disinfection program can be pre-set in the system program based on factors such as the type of surgery, the amount of waste liquid, and the type of disinfectant. The operator can execute the disinfection program after setting various factors. For example, for a specific type of surgery and a specific amount of waste liquid, the disinfection program can be circulated and disinfected for 15 minutes, or circulated 15 times and then left to stand for half an hour. These can be set and changed according to the actual surgical needs and the requirements of the medical site, and will not be described in detail.

[0095] After the disinfection process is completed, the drainage operation is performed. The principle is as follows:

[0096] The operator selects to execute the drain operation via the docking control panel of the docking device 32 or the collection control panel of the waste liquid collection device 31. After the operator triggers the drain procedure, the control module 502 closes the switching valve 422 and opens the drain control valve 432. This switches the pipeline 430, closing and shutting off the input liquid path 4102 and the discharge liquid path 420. Simultaneously, the discharge port 423 is opened, interrupting the circulation path formed by the input liquid path 4102 and the discharge liquid path 420 for liquid circulation. The drain pump 423 is activated, sucking the liquid from the waste liquid collection container 1092 through the suction connector 212 and discharging the disinfected waste liquid through the discharge port 423.

[0097] After the drainage operation is performed, the waste liquid collection container 1092 is flushed. The principle is as follows:

[0098] The operator selects to perform the flushing operation through the docking control panel of the docking device 32 or the collection control panel of the waste liquid collection device 31. At this time, the input liquid circuit 4102 (i.e., the flushing liquid circuit 4102) and the discharge liquid circuit 420 are not connected to each other. The control module 502 opens the tap water control valve 447 to allow tap water to enter the liquid adding pipeline, and controls the second liquid adding pump 444 according to the tap water flow rate to pump the cleaning liquid in the second liquid adding container 444 into the liquid adding pipeline 4401 according to the preset flushing setting, and the tap water mixed with the cleaning liquid passes through the input liquid circuit 4101. After the flushing program is started, the control module 502 opens the third branch control valve 416 to connect the third input branch 413, and closes the first branch control valve 414 to cut off the first input branch 411. The cleaning liquid and tap water entering the input liquid path 4102 are used to flush the first inner cavity 116 and the second inner cavity 117 of the waste liquid collection container 1092 through the third input branch 413 and the flushing terminal connected thereto. At this time, the first inner cavity 116 and the second inner cavity 117 are in a connected state. After the flushing is completed, the liquid in the waste liquid collection container 1092 can be drained.
