Description

Technical Field

[0001] The present invention relates to a docking device for docking with a waste liquid collection device for collecting and processing waste liquid materials generated in a medical process, a waste liquid collection and processing system, and a waste liquid processing method. 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, to address this technical shortcoming, a transfer device specifically designed to transport waste liquid from a waste liquid collection device to a docking station has been developed. This docking device is specifically designed to transport waste liquid from a waste liquid collection device. This device typically includes two connectors that dock with two connectors on the waste liquid collection device to form a fluid path. One fluid path is used to transfer waste liquid from the waste liquid collection device to the docking device, and the other fluid path is used to clean the waste liquid collection container of the waste liquid collection device. Before the docking device flushes the waste liquid collection device, it is necessary to confirm that the waste liquid in the waste liquid collection device has been emptied. In the prior art, this is done by inserting a float valve into the waste liquid collection container of the waste liquid collection device or by installing a detection sensor in the waste liquid collection container to confirm whether the docking device has emptied the waste liquid from the waste liquid collection device (see US Patent No. 200501887529A1 and US Patent No. 7879228). In other words, whether it is a float valve or a liquid level sensor, data must be transmitted to the docking device via the electronic components in the waste liquid collection device to trigger the docking device to flush the waste liquid collection device.

[0005] The detection sensors of the prior art have the following disadvantages: the float valve or other prior art liquid level sensors need to be placed or installed in the waste liquid collection container and need to be in contact with the waste liquid, and the structure needs to be drilled during installation, which is extremely inconvenient for the one-piece waste liquid collection container to install. At the same time, if placed in the waste liquid collection container, it will affect the strength and sealing effect of the container, and the installation is complicated and the installation cost is high. In addition, the float valve and other contact liquid level sensors in the prior art are easily corroded by waste liquid, cleaning liquid and disinfectant, and are easily affected by scale. They have a short lifespan and cannot be replaced or maintained, which will greatly increase the cost of using the equipment. At the same time, since the detection sensor is directly connected to the waste liquid collection container, when the waste liquid collection device and the docking device are docked, the waste liquid collection device must be powered on to transmit the data of the detection sensor to the docking device. This operation will cause the waste liquid collection device to be disconnected, affecting the electrical components. At the same time, the waste liquid sensor needs to be operated, which brings inconvenience to the user. In addition, for a waste liquid collection device having multiple waste liquid collection containers, it is necessary to detect whether the liquid in each waste liquid collection container is emptied. The prior art adopts a method of installing a detection sensor for each waste liquid collection container to achieve this, see patent No. US7879228. For a device having multiple waste liquid collection containers, the prior art solution increases the amount of sensors used, resulting in increased manufacturing costs. Summary of the Invention

Directional terms used herein, such as "upper," "lower," "front," "rear," "left," "right," "inner," "outer," and "side," refer only to the directions in the accompanying drawings. Therefore, these directional terms are intended to facilitate explanation and understanding of the present invention and are not intended to limit the present invention.

[0073] In order to make the objectives, technical solutions and advantages of the present invention more clear, the present invention will be described in further detail below with reference to the accompanying drawings.

[0074] like Figure 1-Figure 5 As shown, Figure 1 and Figure 2 A waste liquid collection and treatment system 10 is shown, which includes a waste liquid collection device 100 and a docking device 200. Figure 1 The waste liquid collection and treatment system 10 is in a state where the waste liquid collection device 100 and the docking device 200 are not docked. Figure 2 The waste liquid collection device 100 and the docking device 200 are docked in the waste liquid collection and treatment system 10. The waste liquid collection device 100 can be docked with the consumable box 300. Figure 6The external suction line 310 shown is connected to the consumables box external connector 301. The consumables box external connector can be a separate connector or attached to the surgical equipment. The suction force at the consumables box external connector transports the waste liquid through the external suction line to the waste liquid collection device 100 for storage. After the docking device 200 is docked with the waste liquid collection device 100, the waste liquid in the waste liquid collection device 100 can be emptied through the docking device 200. After the waste liquid in the waste liquid collection device 100 is emptied, the docking device 200 and the waste liquid collection device 100 can also form a cleaning passage for cleaning the waste liquid collection container 109 of the waste liquid collection device 100 through the docking of the docking device 200 and the waste liquid collection device 100.

[0075] See also Figure 3 and Figure 5 As shown, Figure 3 for Figure 1 The schematic diagram of part of the internal structure of the waste liquid collection equipment in the waste liquid collection and treatment system shown in FIG. Figure 5 This is a schematic diagram of the connection principle of the first embodiment of the waste liquid collection and treatment system provided by the present invention. Figure 3 and Figure 5 As shown, the waste liquid collection device 100 is provided with a liquid discharge joint 112 for discharging waste liquid from the waste liquid collection container 109, and a liquid inlet joint 114 for introducing external liquid into the waste liquid collection container 109. The liquid discharge joint 112 and the liquid inlet joint 114 are both connected to the waste liquid collection container 109. Figure 1-Figure 4 As shown, Figure 1 and Figure 3 As shown, the waste liquid collection device 100 is provided with two floating sleeves 111, 113, which are correspondingly sleeved on the drainage joint 112 and the liquid inlet joint 114, and are used to guide the suction joint 212 of the docking device 200 to be connected to the drainage joint 112, and the liquid supply joint 214 to be connected to the liquid inlet joint 114; the two floating sleeves 111, 113 can be suspended and moved relative to the matching bracket 110 and guide the suction joint 212, the drainage joint 112 to the liquid supply joint 214, and the liquid inlet joint 114 to be connected accordingly. Figure 6-Figure 8, the waste liquid collection container 109, the collection end connector 312, the liquid inlet connector 114 and the discharge connector 112, the liquid collection container 109, are connected to the negative pressure source 461 in an air path; the collection end connector 312 is connected to the liquid inlet of the waste liquid collection container 109 and is connected to the suction device for introducing waste liquid generated during the medical process, and the collection end connector 312 and the consumable box 300 are connected through a collection liquid path 450; the liquid inlet connector 114 is connected to the flushing port 1094 of the waste liquid collection container 109 and is used to dock with the liquid feeding connector 214 of the docking device 200 to form a flushing liquid path 440 for injecting liquid into the waste liquid collection container 109 of the waste liquid collection device 100 to clean the waste liquid collection container 109; the discharge connector 112 is connected to the discharge port 1093 of the waste liquid collection container 109 and is used to dock with the suction connector 212 of the docking device 200 to form a discharge liquid path 420 for extracting the liquid in the waste liquid collection container 109. The negative pressure port 1092 of the waste liquid collection container 109 is connected to a negative pressure source 461 through a negative pressure air path 460 . The negative pressure source 461 may be provided inside the waste liquid collection device 100 or may be an external negative pressure source.

[0076] like Figure 5As 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 collection and treatment system 10. The docking device 200 includes: a suction connector 212, a liquid supply connector 214, a liquid discharge pump 421, a detection device 430 and a control unit 500. The suction joint 212 is docked with the discharge joint 112 of the waste liquid collection device 100 to form a discharge pipeline 420 for discharging the liquid in the waste liquid collection container 109 of the waste liquid collection device 100; the liquid supply joint 214 is docked with the liquid inlet joint 114 of the waste liquid collection device 100 to form a cleaning pipeline 440 for injecting liquid into the waste liquid collection device 100 to clean the waste liquid collection container 109; the discharge pump 421 is arranged in the discharge pipeline 420, and is used to discharge the liquid in the waste liquid collection container 109 through the discharge pipeline 420 after starting the discharge program; the detection device 430 is used to detect whether there is liquid passing through the part of the discharge pipeline 420 located in the docking device 200, and the detection device 430 is not in direct contact with the waste liquid collection container 109; when the detection device 430 feedback detects that no liquid passes, the control unit 500 controls the addition of liquid into the cleaning pipeline 440 to perform the cleaning operation of the waste liquid collection container 109. In this embodiment, the drainage program is a drainage logic executable by the device, which can be triggered automatically or manually. The automatic triggering can be automatically started after the waste liquid collection device 100 and the docking device 200 complete the docking, or it can be manually started through the touch screen or operation buttons. The drainage program mainly discharges the liquid in the waste liquid collection container 109 through the discharge pipe 420 by the drainage pump 421. After starting the drainage program, the cleaning pipe is in a closed state. The end of the discharge pipe 420 is a discharge port 421, wherein a drainage control valve 422 is also provided between the drainage pump 421 and the discharge port 423 for closing or opening the discharge port 423. The discharge port 423 can be directly a hose connector connected to the excretion channel, or it can be a connector that can be connected to a hose, for example Figure 4 The discharge connector 208 shown can be connected to the discharge port 423 of the additional sewage pipe. In this embodiment, the waste liquid collection container 109 can be Figure 5 The single cavity structure shown can also be Figure 3 as well as Figure 5 - As shown in FIG8 , the multi-cavity structure including the first inner cavity 116 and the second inner cavity 117 that can be communicated with and isolated from each other can also contain multiple collection containers 109.

[0077] In this embodiment, the detection device 430 is located between the suction connector 212 of the discharge line 420 and the drainage pump 421, near the suction connector 212. That is, after the waste liquid collection device 100 and the docking device 200 are docked, the detection device 430 is located near the drainage port 1093 of the waste liquid collection device 100. This allows immediate detection of whether liquid is flowing through the discharge line 420, thereby minimizing the idling time of the drainage pump 421. In other embodiments, if the discharge line 420 is short and the drainage pump 421 is powerful, the location of the detection device 430 can be adjusted based on the wiring requirements of the docking device 200. The detection device 430 can be a non-contact water sensor. In this embodiment, the detection device 430 is a non-contact water sensor (liquid level sensing switch). The working principle of this sensor is to use the inductive capacitance of water to detect the presence of liquid. When there is no liquid approaching the sensor, the sensor has a certain static capacitance to the ground due to the presence of distributed capacitance. When the liquid level slowly rises and approaches the sensor, the parasitic capacitance of the liquid will couple to this static capacitance, causing the final capacitance value of the sensor to increase. This changing capacitance signal is then input into the control chip for signal conversion, converting the changing capacitance into a certain amount of change in an electrical signal. A predetermined algorithm is then used to detect and determine the extent of this change. When this amount of change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point. The non-contact water sensor overcomes the influence of container wall thickness and realizes non-contact detection of the liquid level height in a sealed container. See. Figure 9 As shown, the detection device 430 is disposed outside the discharge pipe 420, preferably in close contact with the outer wall of the discharge pipe 420, and can be attached to the outer wall of the discharge pipe 420 by gluing, welding, or binding. No holes are required for non-metallic containers, installation is simple, and does not affect production. It can detect the liquid levels of various toxic substances, strong acids, strong bases, and various liquids in high-pressure sealed containers. In other embodiments, the detection device 430 can be a non-contact water sensor. In addition, the detection device 430 can also be other types of non-contact sensors with liquids, such as a through-beam photoelectric sensor.

[0078] For details, see Figure 6 , Figure 6 The schematic diagram of the drainage of the docking device 200 and the waste liquid collection device 100 is shown. After the drainage program is started, the drainage pump 421 works to suck the liquid in the waste liquid collection container 109 and drains it along the drainage pipe 420. Figure 6The liquid is discharged in the direction of the arrow shown. At this time, liquid passes through the discharge pipe 420, and the detection device 430 feedbacks a signal indicating that liquid passes through the sensing point. When the liquid in the waste liquid collection container 109 is emptied, no liquid passes through the discharge pipe 420, and the detection device 430 cannot detect the liquid, and feedback indicates that no liquid passes through the sensing point. At this time, the control unit 500 determines that the liquid in the waste liquid collection container 109 is emptied based on the signal that no liquid passes through the sensing point, controls the liquid discharge pump 421 to be turned off, and the liquid discharge pipe 420 is closed. At the same time, it controls the addition of liquid into the cleaning pipe 440 to perform the cleaning operation of the waste liquid collection container 109. Figure 5 and Figure 8 , Figure 8 This is a schematic diagram of flushing the docking device 200 and the waste liquid collection device 100. At this time, the water control valve 447 is controlled to open to introduce liquid for cleaning. The liquid comes from the tap water pipe and is specifically connected to the tap water through the water inlet 448 (the water inlet 448 can be Figure 4 As shown in the interface 207), use the tap water pressure according to Figure 8 The flushing pressure in the direction of the arrow shown in the figure is driven by the flushing head 1095 through the flushing line 440 to flush the inner wall of the waste liquid collection container 109. The water inlet 448 can also be directly connected to the flushing pump to generate flushing pressure. Figure 5 and Figure 8 The docking device 100 further includes a liquid adding pump 443, which is connected to the cleaning pipeline 440 and is used to press the liquid adding pump 443 after the control unit 500 controls the cleaning operation. Figure 8 In the direction of the arrow shown, a cleaning liquid 445 is injected into the waste liquid collection container 109 to clean the waste liquid collection container 109 , wherein the cleaning liquid 445 is stored in the liquid container 441 . The flushing liquid 445 can be a detergent or a mixed liquid of a detergent and a disinfectant.

[0079] Since the discharge pipe 420 is not immediately filled with liquid when the liquid discharge pump 421 is just started, the detection device 430, if relatively sensitive, will feedback a signal indicating that no liquid is passing through the sensing point, and the control unit 500 will control the liquid discharge pump 421 to be shut down. At this time, the liquid in the waste liquid collection container 109 has not yet been discharged, and the liquid discharge process is stopped. In order to solve the problem that the detection device 430 is too sensitive and causes the liquid discharge pump to be shut down before the liquid is discharged, the detection device 430 can be turned on after a first preset time has passed after the liquid discharge process is started. That is, the detection device 430 is not operated for a first preset time after the liquid discharge pump 421 is started. After the first preset time has passed, the detection device 430 is turned on again. At this time, liquid is passing through the discharge pipe 420, and the detection device 430 feedbacks a signal indicating that liquid is passing through the sensing point, and the liquid discharge pump 421 continues to execute the liquid discharge process until the liquid in the waste liquid collection container 109 is emptied. Alternatively, after the detection device 430 provides feedback to the control unit 500 after the drainage program is started, the control unit 500 ignores the feedback from the detection device 430 within the first preset time. This approach can also solve the problem of the detection device 430 being too sensitive and causing the drainage pump to be shut down before drainage. The first preset time can be calculated or estimated based on the distance from the detection device 430 to the drainage port 1093 of the waste liquid collection container 109, the diameter of the drainage pipeline 420, and the parameters of the drainage pump 421.

[0080] In this embodiment, after the cleaning operation of the waste liquid collection container 109 is completed, the liquid generated by the cleaning is stored in the waste liquid collection device 109, and the liquid generated by the cleaning also needs to be emptied. At this time, the draining program can be automatically started again to empty the liquid generated by the flushing in the waste liquid collection device 109. This process has been described above and will not be repeated here.

[0081] In addition, in this embodiment, the waste liquid collection container 109 can be rinsed multiple times to meet the cleanliness requirements. The number of rinses can be set according to the amount of waste liquid, or it can be built into the program. When multiple rinse operations are performed, the drainage program is automatically started after each rinse operation is completed. During this process, the control unit 500 is also used to calculate the number of times the waste liquid collection container 109 is rinsed. When the preset number of rinses is reached and the liquid in the waste liquid collection container 109 is finally discharged, the waste liquid processing is stopped.

[0082] The implementation of the embodiments of the present invention has the following beneficial effects:

[0083] First, the detection device in this embodiment is installed on the docking device rather than directly on the waste liquid collection device, and does not need to be physically connected to the waste liquid collection container. Therefore, there is no need to make additional holes in the waste liquid collection container or add additional accessories, which can greatly reduce the difficulty and cost of installation, maintenance and replacement.

[0084] Second, during the operation, the detection device does not need to be immersed in the waste liquid collection container of the waste liquid collection equipment. It will not be corroded by medical waste liquid and disinfectants, and will not form scale, thus extending its service life without affecting the detection accuracy.

[0085] Third, since the detection device is only installed in the docking device, in most cases, the waste liquid collection device does not need to provide data on the amount of liquid in the waste liquid collection container when discharging the waste liquid in the waste liquid collection device, and no electrical connection or signal transmission is required between the waste liquid collection device and the docking device. Therefore, there is no need to charge the waste liquid collection device, and there is no need to operate the waste liquid collection device. It is only necessary to dock the waste liquid collection device and the docking device, which is convenient for users to operate;

[0086] Fourth, since the detection device is installed outside the waste liquid collection container, the waste liquid collection device can be manufactured through one-piece molding, thereby enhancing the sealing performance and strength;

[0087] Fifth, for waste liquid collection equipment with multiple waste liquid collection containers or multi-cavity waste liquid collection containers, only one detection device needs to be installed on the docking device to complete the detection of liquids in multiple waste liquid collection containers or multi-cavity waste liquid collection containers, reducing the number of accessories and reducing equipment costs, while reducing internal wiring and simplifying the installation process.

[0088] Accordingly, see Figure 7 and Figure 8 As shown, an embodiment of the present invention further provides a waste liquid collection and treatment system 10, comprising: a waste liquid collection container 109, a drainage pump 421, a detection device 430, and a control unit 500. The waste liquid collection container 109 includes a liquid inlet 1091 for directly or indirectly connecting to an external suction pipeline (not shown) and introducing medical waste liquid, a negative pressure port 1092 for directly or indirectly connecting to a negative pressure source 461, a drainage port 1093 for discharging liquid, and a flushing head 1095 connected to a cleaning pipeline 440 for flushing the waste liquid collection container 109. The drainage pump 421 is fluidically connected to the drainage port 1093, and at least one section of the drainage pipeline 420 is provided between the drainage pump 421 and the waste liquid collection container 109. The detection device 430 is configured to detect whether liquid is flowing through the drainage pipeline 420. When the detection device detects that no liquid is flowing, the control unit 500 controls the addition of liquid into the cleaning pipeline 440 to perform a cleaning operation on the waste liquid collection container 109. In this embodiment, the waste liquid collection container 109 is indirectly connected to the suction pipeline (not shown in the figure) through the consumable box 300.

[0089] Figure 7In the embodiment shown, the waste liquid collection container 109 and the detection device 430 are located in the waste liquid collection device 100, and the drainage pump 421 and the control unit 500 are located in the docking device 200, wherein the detection device 430 and the control unit 500 have a direct or indirect signal connection or electrical connection. Figure 6 and Figure 5 In the illustrated embodiment, the detection device 430 is located inside the docking device 200 .

[0090] See also Figure 7 The waste liquid collection device 100 includes: a waste liquid collection container 109, a collection end connector 312, a liquid inlet connector 114, a liquid discharge connector 112 and a detection device 430. The liquid collection container 109 is connected to the negative pressure source 461 by air; the collection end connector 312 is connected to the liquid inlet of the waste liquid collection container 109 and is connected to the suction device for introducing waste liquid generated during the medical process. The collection end connector 312 and the consumable box 300 are connected via a collection liquid path 450; the liquid inlet connector 114 is connected to the flushing port 1094 of the waste liquid collection container 109 and is used to dock with the liquid supply connector 214 of the docking device 200 to form a flushing liquid path 440 for injecting liquid into the waste liquid collection container 109 of the waste liquid collection device 100 to clean the waste liquid collection container 109; the discharge connector 112 is connected to the discharge port 1093 of the waste liquid collection container 109 and is used to dock with the suction connector 212 of the docking device 200 to form a discharge liquid path 420 for extracting liquid from the waste liquid collection container 109. The negative pressure port 1092 of the waste liquid collection container 109 is connected to a negative pressure source 461 through a negative pressure air path 460 . The negative pressure source 461 may be provided inside the waste liquid collection device 100 or may be an external negative pressure source.

[0091] 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 collection and treatment system 10. The docking device 200 includes: a suction connector 212, a liquid supply connector 214, a drainage pump 421 and a control unit 500. The suction connector 212 is docked with the discharge connector 112 of the waste liquid collection device 100 to form a discharge pipeline 420 for discharging the liquid in the waste liquid collection container 109 of the waste liquid collection device 100; the liquid supply connector 214 is docked with the liquid inlet connector 114 of the waste liquid collection device 100 to form a cleaning pipeline 440 for injecting liquid into the waste liquid collection device 100 to clean the waste liquid collection container 109; the discharge pump 421 is arranged in the discharge pipeline 420, and is used to discharge the liquid in the waste liquid collection container 109 through the discharge pipeline 420 after starting the discharge program; when the detection device 430 feedback detects that no liquid passes through, the control unit 500 controls the addition of liquid into the cleaning pipeline 440 to perform the cleaning operation of the waste liquid collection container 109.

[0092] In this waste liquid collection and treatment system 10, the liquid path between the drainage pump 421 and the drainage port 1093 is connected, and at least a section of the discharge pipeline 420 is included between the drainage pump 421 and the waste liquid collection container 109; the detection device 430 is used to detect whether there is liquid passing through the discharge pipeline 420; the detection device 430 is used to detect whether there is liquid passing through the part of the discharge pipeline 420 located in the docking device 200, and the detection device 430 is not in direct contact with the waste liquid collection container 109.

[0093] In this embodiment, the drainage program is a drainage logic executable by the device, which can be triggered automatically or manually. The automatic triggering can be automatically started after the waste liquid collection device 100 and the docking device 200 complete the docking, or it can be manually started through the touch screen 103 or the operation button. The drainage program mainly discharges the liquid in the waste liquid collection container 109 through the discharge pipe 420 by the drainage pump 421. After starting the drainage program, the cleaning pipe is in a closed state. The front end of the discharge pipe 420 is connected to the discharge port 1093 of the waste liquid collection container 109, and the end is a discharge port 421, wherein a drainage control valve 422 is also provided between the drainage pump 421 and the discharge port 423 for closing or opening the discharge port 423. The discharge port 423 can be directly a hose connector connected to the excretion channel, or it can be a connector that can be connected to a hose, for example Figure 4 The discharge connector 208 shown can be connected to the discharge port 423 of the additional sewage pipe. In this embodiment, the waste liquid collection container 109 can be Figure 5 The single cavity structure shown can also be Figure 3 as well as Figure 5 - As shown in FIG8 , the multi-cavity structure including the first inner cavity 116 and the second inner cavity 117 that can be communicated with and isolated from each other can also contain multiple collection containers 109.

[0094] In this embodiment, the detection device 430 is located within the waste liquid collection device 100 and in the portion of the discharge pipe 420 near the liquid outlet. Specifically, after the waste liquid collection device 100 and the docking device 200 are docked, the detection device 430 is located near the liquid outlet 1093 of the waste liquid collection device 100. This allows the detection device 430 to immediately detect whether liquid is flowing through the discharge pipe 420, thereby minimizing the idling time of the liquid pump 421. The detection device 430 can be a non-contact water sensor. In this embodiment, the detection device 430 is a non-contact water sensor (liquid level sensing switch). The working principle of this sensor is to use the inductive capacitance of water to detect the presence of liquid. When there is no liquid approaching the sensor, the sensor has a certain static capacitance to the ground due to the presence of distributed capacitance. When the liquid level slowly rises and approaches the sensor, the parasitic capacitance of the liquid will couple to this static capacitance, causing the final capacitance value of the sensor to increase. This changing capacitance signal is then input into the control chip for signal conversion, converting the changing capacitance into a certain amount of change in an electrical signal. A predetermined algorithm is then used to detect and determine the extent of this change. When this amount of change exceeds a certain threshold, it is considered that the liquid level has reached the sensing point. The non-contact water sensor overcomes the influence of container wall thickness and realizes non-contact detection of the liquid level height in a sealed container. See. Figure 9 As shown, the detection device 430 is arranged on the outside of the discharge pipe 420, preferably, it is closely attached to the outer wall of the discharge pipe 420, and can be attached to the outer wall of the discharge pipe 420 by pasting, welding or binding. Preferably, the direction of the discharge pipe 420 at the position where the detection device 430 is located can be adjusted, and the up and down directions can be used to reduce the influence of gravity on the detection. For non-metallic containers, no holes need to be opened, the installation is simple, and it does not affect production. It can realize the detection of the liquid levels of various toxic substances, strong acids, strong alkalis and various liquids in high-pressure sealed containers. In other embodiments, the detection device 430 can be a non-contact water sensing sensor.

[0095] For details, see Figure 7 , Figure 7 The schematic diagram of the drainage of the docking device 200 and the waste liquid collection device 100 is shown. After the drainage program is started, the drainage pump 421 works to suck the liquid in the waste liquid collection container 109 and drains it along the drainage pipe 420. Figure 6The liquid is discharged in the direction of the arrow shown. At this time, liquid passes through the discharge pipe 420, and the detection device 430 feedbacks a signal indicating that liquid passes through the sensing point. When the liquid in the waste liquid collection container 109 is emptied, no liquid passes through the discharge pipe 420, and the detection device 430 cannot detect the liquid, and feedback indicates that no liquid passes through the sensing point. At this time, the control unit 500 determines that the liquid in the waste liquid collection container 109 is emptied based on the signal that no liquid passes through the sensing point, controls the liquid discharge pump 421 to be turned off, and the liquid discharge pipe 420 is closed. At the same time, it controls the addition of liquid into the cleaning pipe 440 to perform the cleaning operation of the waste liquid collection container 109. Figure 5 and Figure 8 , Figure 8 This is a schematic diagram of flushing the docking device 200 and the waste liquid collection device 100. At this time, the water control valve 447 is controlled to open to introduce the liquid for cleaning. The liquid comes from the tap water pipe and is specifically connected to the tap water through the water inlet 448. The tap water pressure is adjusted according to the pressure of the tap water. Figure 8 The flushing pressure in the direction of the arrow shown in the figure is driven by the flushing head 1095 through the flushing line 440 to flush the inner wall of the waste liquid collection container 109. The water inlet 448 can also be directly connected to the flushing pump to generate flushing pressure. Figure 5 and Figure 8 The docking device 100 further includes a liquid adding pump 443, which is connected to the cleaning pipeline 440 and is used to press the liquid adding pump 443 after the control unit 500 controls the cleaning operation. Figure 8 In the direction of the arrow shown, a cleaning liquid 445 is injected into the waste liquid collection container 109 to clean the waste liquid collection container 109 , wherein the cleaning liquid 445 is stored in the liquid container 441 . The flushing liquid 445 can be a detergent or a mixed liquid of a detergent and a disinfectant.

[0096] Since the discharge pipe 420 is not immediately filled with liquid when the liquid discharge pump 421 is just started, the detection device 430, if relatively sensitive, will feedback a signal indicating that no liquid is passing through the sensing point, and the control unit 500 will control the liquid discharge pump 421 to be shut down. At this time, the liquid in the waste liquid collection container 109 has not yet been discharged, and the liquid discharge process is stopped. In order to solve the problem that the detection device 430 is too sensitive and causes the liquid discharge pump to be shut down before the liquid is discharged, the detection device 430 can be turned on after a first preset time has passed after the liquid discharge process is started. That is, the detection device 430 is not operated for a first preset time after the liquid discharge pump 421 is started. After the first preset time has passed, the detection device 430 is turned on again. At this time, liquid is passing through the discharge pipe 420, and the detection device 430 feedbacks a signal indicating that liquid is passing through the sensing point, and the liquid discharge pump 421 continues to execute the liquid discharge process until the liquid in the waste liquid collection container 109 is emptied. Alternatively, after the detection device 430 provides feedback to the control unit 500 after the drainage program is started, the control unit 500 ignores the feedback from the detection device 430 within the first preset time. This approach can also solve the problem of the detection device 430 being too sensitive and causing the drainage pump to be shut down before drainage. The first preset time can be calculated or estimated based on the distance from the detection device 430 to the drainage port 1093 of the waste liquid collection container 109, the diameter of the drainage pipeline 420, and the parameters of the drainage pump 421.

[0097] In this embodiment, after the cleaning operation of the waste liquid collection container 109 is completed, the liquid generated by the cleaning is stored in the waste liquid collection device 109, and the liquid generated by the cleaning also needs to be emptied. At this time, the draining program can be automatically started again to empty the liquid generated by the flushing in the waste liquid collection device 109. This process has been described above and will not be repeated here.

[0098] In addition, in this embodiment, the waste liquid collection container 109 can be rinsed multiple times to meet the cleanliness requirements. The number of rinses can be set according to the amount of waste liquid, or it can be built into the program. When multiple rinse operations are performed, the drainage program is automatically started after each rinse operation is completed. During this process, the control unit 500 is also used to calculate the number of times the waste liquid collection container 109 is rinsed. When the preset number of rinses is reached and the liquid in the waste liquid collection container 109 is finally discharged, the waste liquid processing is stopped.

[0099] The implementation of the embodiments of the present invention has the following beneficial effects:

[0100] First, the detection device in this embodiment is installed outside the waste liquid collection container and does not need to be physically connected to the waste liquid collection container. Therefore, there is no need to make additional holes in the waste liquid collection container or add additional accessories, which can greatly reduce the difficulty and cost of installation, maintenance and replacement;

[0101] Second, during the operation, the detection device does not need to be immersed in the waste liquid collection container of the waste liquid collection equipment. It will not be corroded by medical waste liquid and disinfectants, and will not form scale, thus extending its service life without affecting the detection accuracy.

[0102] Third, since the detection device is installed outside the waste liquid collection container, the waste liquid collection equipment can be manufactured through one-piece molding, which enhances the sealing performance and strength;

[0103] Fourth, for waste liquid collection equipment with multiple waste liquid collection containers or multi-cavity waste liquid collection containers, only one detection device needs to be installed on the docking device to complete the detection of liquids in multiple waste liquid collection containers or multi-cavity waste liquid collection containers, reducing the number of accessories and reducing equipment costs, while reducing internal wiring and simplifying the installation process.

[0104] Combine Figures 1-6 as well as Figure 12 The embodiment of the present invention further provides a waste liquid treatment method for treating medical waste liquid in a waste liquid collection and treatment system 10.

The waste liquid collection and treatment system 10 is shown in FIG. Figures 1-8 As shown, the waste liquid treatment method includes:

[0105] Step 100: The waste liquid collection device 100 and the docking device 200 are docked and the drainage process is started;

[0106] Step 200: draining the liquid in the waste liquid collection container 109 of the waste liquid collection device 100 through the discharge pipeline 420 and the discharge pump 421 located in the discharge pipeline 420;

[0107] Step 300: Determine whether liquid passes through the discharge pipe according to the detection result of the detection device 430; if yes, execute step 200; otherwise, execute step 400;

[0108] Step 400: The control unit 500 of the docking device 200 controls and performs a cleaning operation on the waste liquid collection container 109;

[0109] Step 500 : After the cleaning operation is completed, the flushing waste liquid in the waste liquid collection container 109 is discharged through the discharge pipeline 420 and the drainage pump 421 located in the discharge pipeline 420 .

[0110] Furthermore, the waste liquid treatment method also includes:

[0111] Step 600: Determine whether liquid passes through the discharge pipe 420 according to the detection result of the detection device 430. If yes, execute step 500; otherwise, execute step 700.

[0112] Step 700: Determine whether the flushing operation has reached a preset number of times. If so, end the waste liquid treatment; if not, execute step 400.

[0113] The process of determining whether liquid passes through the discharge pipe 420 according to the detection result of the detection device 430 specifically includes:

[0114] Step 11: The detection device 430 is activated after a first preset time has passed;

[0115] Step 12: The detection device 430 feeds back a detection signal to the control unit 500;

[0116] Step 13: When the detection signal is a liquid signal, the control unit 500 determines that liquid is passing through the discharge pipe 420; otherwise, it determines that no liquid is passing through the discharge pipe 420. The liquid signal indicates that liquid is passing through the sensing point where the detection device 430 is located.

[0117] Furthermore, judging whether there is liquid flowing through the discharge pipe 420 according to the detection result of the detection device 430 specifically includes:

[0118] Step 21: The detection device 430 is started;

[0119] Step 22: The detection device 430 feeds back a detection signal to the control unit 500;

[0120] Step 23: After the control unit 500 ignores the detection signal fed back by the detection device 430 within the first preset time, when the detection signal is a liquid signal, the control unit 500 determines that liquid passes through the discharge pipe 420; otherwise, it determines that no liquid passes through the discharge pipe 420.

[0121] The implementation of the embodiments of the present invention has the following beneficial effects:

[0122] First, the detection device in this embodiment is installed on the docking device rather than directly on the waste liquid collection device, and does not need to be physically connected to the waste liquid collection container. Therefore, there is no need to make additional holes in the waste liquid collection container or add additional accessories, which can greatly reduce the difficulty and cost of installation, maintenance and replacement.

[0123] Second, during the operation, the detection device does not need to be immersed in the waste liquid collection container of the waste liquid collection equipment. It will not be corroded by medical waste liquid and disinfectants, and will not form scale, thus extending its service life without affecting the detection accuracy.

[0124] Third, if the detection device is only installed in the docking device, in most cases, when discharging the waste liquid in the waste liquid collection device, the waste liquid collection device does not need to provide data on the amount of liquid in the waste liquid collection container, and no electrical connection or signal transmission is required between the waste liquid collection device and the docking device. Therefore, there is no need to power the waste liquid collection device, and there is no need to operate the waste liquid collection device. It is only necessary to dock the waste liquid collection device and the docking device, which is convenient for users to operate.

[0125] Fourth, since the detection device is installed outside the waste liquid collection container, the waste liquid collection device can be manufactured through one-piece molding, thereby enhancing the sealing performance and strength;

[0126] Fifth, for waste liquid collection equipment with multiple waste liquid collection containers or multi-cavity waste liquid collection containers, only one detection device needs to be installed on the docking device to complete the detection of liquids in multiple waste liquid collection containers or multi-cavity waste liquid collection containers, reducing the number of accessories and reducing equipment costs, while reducing internal wiring and simplifying the installation process.

[0127] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
