[0043] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0044] Oncology, like internal medicine, surgery, obstetrics and gynecology, and pediatrics, is a secondary discipline of clinical medicine, divided into internal oncology, tumor radiotherapy, and tumor surgery. Internal oncology is mainly engaged in the medical treatment of various benign and malignant tumors. The tumor radiotherapy department is mainly engaged in the radiation treatment of tumors. The tumor surgery provides comprehensive treatment with surgery as the main focus. The relevant departments of specialized tumor hospitals will be further subdivided according to different parts, such as the gastrointestinal tumor department and lymphoma tumor department in the internal oncology department, and the tumor surgery department includes breast surgery, head and neck surgery, thoracic surgery, tumor gynecology, abdominal surgery, etc. During the treatment of tumors, it is usually necessary to extract the accumulated fluid inside the tumor, and a fluid extraction device is usually required.

[0045] As described in the background technology, when using the existing effusion extraction device, the air bag is pressed to insert the needle into the part where the effusion needs to be extracted, and the air bag is released. The effusion will flow into the collection bottle through the drainage tube, and the separator can collect the layered effusion, and the effusion can be sampled in layers to make the test results more accurate. Specifically, after the effusion is extracted, part of the effusion will enter the separator. When the effusion needs to be sampled, the shunt tube connected to the separator can be opened, and the effusion collected by the separator can be collected through the shunt tube.

[0046] Since the effusion contains certain suspended matter, the suspended matter may easily clog the effusion extraction device when the above-mentioned effusion extraction device is in use, thus affecting the correct use of the effusion extraction device. For example, since the separator is conical, and the end connected to the shunt tube is a small-diameter end, when the effusion contains a large amount of suspended matter, the suspended matter may clog the small-diameter end of the separator or the shunt tube, making it difficult for the effusion extraction device to drain the liquid, thus affecting the normal use of the effusion extraction device. It should be noted that the suspended matter is usually human tissue in the effusion.

[0047] In view of this, the embodiment of the present application provides a fluid extraction device, which can filter and clean the suspended matter in the fluid through the setting of the filter and the cleaning part in the fluid extraction device to ensure the normal use of the fluid extraction device. The fluid in the present application may include but is not limited to the fluid inside the tumor.

[0048] The following is a further description of the effusion extraction device of the embodiment of the present application in conjunction with the drawings and examples.

[0049] See also Figure 1 and Figure 2 As shown, the effluent extraction device 100 includes a filter box 10 and a collector 20. A filter element 12 is provided in the filter box 10. The filter element 12 is configured to filter the effluent so that the suspended matter in the effluent cannot pass through the filter element 12, thereby achieving the filtering function of the filter element 12 on the suspended matter in the effluent. After the filter element 12 filters the effluent, the suspended matter is retained on the surface of the filter element 12. The filter element 12 can be a filter net, a filter membrane capable of achieving the above functions, or other structures. In the present application, the structure of the filter element 12 is not particularly limited.

[0050] See also Figure 2 As shown, a fixing frame 13 may be further provided in the filter box 10, and the fixing frame 13 may be fixed in the filter box 10 by means of snap connection, fasteners, bonding, etc. The fasteners may be structures such as screws and bolts. The filter element 12 may be installed in the fixing frame 13, so that the filter element 12 is fixed in the filter box 10 by the fixing frame 13, thereby realizing the installation of the filter element 12 in the filter box 10. It should be noted that the filter element 12 may be installed in the fixing frame 13 by means of clamping, bonding, etc.

[0051] In order to facilitate the fixing of the fixing frame 13 in the filter box 10, the fixing frame 13 can adopt a structure that is compatible with (the same as or similar to) the shape of the filter box 10. For example, when the filter box 10 is a prismatic structure, the fixing frame 13 can also be a polygonal frame that is compatible with the structure of the filter box 10. For example, when the filter box 10 is a circular structure (such as a barrel-shaped structure), the fixing frame 13 can also be a circular frame. In the present application, the structures of the fixing frame 13 and the filter box 10 are not particularly limited.

[0052] See also Figure 1 and Figure 2 As shown, the collector 20 is connected to the filter box 10 and is configured to collect the effluent filtered by the filter element 12, so as to collect the filtered effluent through the collector 20. The effluent collected in the collector 20 can be used for tumor treatment.

[0053] Through the arrangement of the filter box 10 and the collector 20 in the effluent extraction device 100, since the filter box 10 is provided with a filter element 12, the effluent can be filtered through the filter element 12 to retain suspended matter in the effluent on the filter element 12. At the same time, the collector 20 can collect the effluent filtered by the filter element 12 to avoid the suspended matter in the effluent from gathering in the collector 20 and affecting the discharge of the effluent from the collector 20, thereby ensuring the normal use of the effluent extraction device 100.

[0054] See also Figure 2 As shown, in order to facilitate the communication between the collector 20 and the filter box 10, a first opening 21 communicating with the interior may be provided on the top of the collector 20, and a second opening communicating with the interior may be provided on the bottom of the filter box 10. After the collector 20 is installed at the bottom of the filter box 10, the first opening 21 and the second opening are arranged opposite to each other, and the collector 20 and the filter box 10 can be communicated through the first opening 21 and the second opening.

[0055] It should be noted that the collector 20 may include but is not limited to a circular structure (such as a barrel-shaped structure). For example, the collector 20 may also be a prismatic structure. In the present application, the structure of the collector 20 is not particularly limited. The collector 20 may be provided with a scale so that the volume of the effusion collected in the collector 20 can be directly read through the scale.

[0056] See also Figure 2As shown, the effusion extraction device 100 also includes a cleaning component 30. The cleaning component 30 includes a cleaning member 31, which is located in the filter box 10 and movably arranged on the surface of the filter element 12. The cleaning member 31 is configured to push the suspended matter on the surface of the filter element 12 to move on the filter element 12 when it moves on the surface of the filter element 12, so as to remove the suspended matter. By setting the cleaning member 31 in the cleaning component 30, the cleaning member 31 can push the suspended matter on the surface of the filter element 12 to move on the filter element 12 when it moves on the surface of the filter element 12, so as to remove the suspended matter, so as to avoid the suspended matter clogging the filter element 12 and affecting the filtering effect of the filter element 12 on the effusion, thereby further ensuring the normal use of the effusion extraction device 100.

[0057] The cleaning member 31 may be a scraper, so that when the scraper moves on the surface of the filter element 12, the scraper can scrape off the suspended matter on the surface of the filter element 12, and push the suspended matter to move on the filter element 12, so as to achieve the purpose of removing the suspended matter on the filter element 12. The scraper may be a rigid structure (non-flexible structure) to enhance the pushing effect of the scraper on the suspended matter. It should be noted that, in some embodiments, the cleaning member 31 may also be other structures that can push the suspended matter to move on the filter element 12. For example, the cleaning member 31 may also be a plurality of filamentary structures. In the present application, the structure of the cleaning member 31 is not particularly limited. In the following, the structure of the effluent extraction device 100 is further explained by taking the cleaning member 31 as a scraper as an example.

[0058] The cleaning member 31 is arranged at an angle with the filter element 12, and the cleaning member 31 contacts the surface of the filter element 12, so that when the cleaning member 31 moves on the surface of the filter element 12, the cleaning member 31 can push the suspended matter to move on the filter element 12, thereby achieving the purpose of removing the suspended matter on the filter element 12. The angle between the cleaning member 31 and the filter element 12 can be understood as the angle between the cleaning member 31 and the plane where the surface of the filter element 12 is located. For example, the angle between the cleaning member 31 and the filter element 12 can be a right angle, so that the cleaning member 31 is perpendicular to the plane where the surface of the filter element 12 is located. Alternatively, the cleaning member 31 can also be arranged obliquely relative to the plane where the surface of the filter element 12 is located. In this case, the angle between the cleaning member 31 and the filter element 12 can be an acute angle or an obtuse angle. In the present application, the angle between the cleaning member 31 and the filter element 12 is not particularly limited.

[0059] See also Figure 2As shown, the effusion extraction device 100 may also include a waste collection box 40 connected to the filter box 10. The waste collection box 40 is located in the moving direction of the cleaning member 31 and is arranged on the side of the filter 12 facing the collector 20 to collect suspended matter. In this way, when the cleaning member 31 moves on the surface of the filter 12, the suspended matter can be collected through the waste collection box 40 to avoid the suspended matter clogging the surface of the filter 12 and affecting the filtering area of ​​the filter 12, thereby ensuring the normal use of the effusion extraction device 100 and further improving the filtering efficiency of the filter 12 for the effusion. In addition, by setting the waste collection box 40, while not affecting the normal use of the effusion extraction device 100, it is also convenient to centrally clean the collected suspended matter.

[0060] The filter box 10 is provided with a discharge slot (not shown) communicating with the interior, and the waste collection box 40 has a third opening (not shown). After the waste collection box 40 is installed and fixed on the filter box 10, the third opening is arranged opposite to the discharge slot, and the waste collection box 40 can be connected to the filter box 10 through the third opening and the discharge slot. Specifically, after the waste collection box 40 is installed on the filter box 10, it can be fixed to the filter box 10 by means of snap connection, fasteners or bonding, so as to fix the waste collection box 40 on the filter box 10.

[0061] See also Figure 2 and Figure 3 As shown, the cleaning assembly 30 may further include a mounting member 32 and a linear moving member 33. One end of the cleaning member 31 away from the filter element 12 is connected to the mounting member 32. The mounting member 32 is slidably disposed in the filter box 10, and is configured to drive the cleaning member 31 to move on the surface of the filter element 12 when sliding in the filter box 10, so that the cleaning member 31 can be driven to move on the surface of the filter element 12 through the mounting member 32, so as to achieve the purpose of cleaning the suspended matter on the filter element 12 by the cleaning member 31. In addition, the installation of the cleaning member 31 in the filter box 10 can be achieved through the mounting member 32.

[0062] In order to realize the sliding setting of the mounting member 32 in the filter box 10, sliders 321 are provided on both sides of the mounting member 32, and a slide groove 14 is provided on the inner wall of the filter box 10, and the length direction of the slide groove 14 is parallel to the moving direction of the cleaning member 31. The slide groove 14 corresponds to the sliding one by one. In other words, each slider 321 is correspondingly provided with a slide groove 14. The slider 321 is slidably set in the slide groove 14 so that the mounting member 32 is slidably set in the filter box 10. And, when the slider 321 slides in the slide groove 14, it can drive the cleaning member 31 to move on the surface of the filter member 12. In some embodiments, the slider 321 can also be set on the inside of the filter box 10 to form a slide rail for the cleaning member 31. At this time, the slide groove 14 can be set at a position of the mounting member 32 opposite to the slider 321, which can also realize the sliding setting of the mounting member 32 in the filter box 10.

[0063] It should be noted that when the mounting member 32 slides in the filter box 10, it can drive the cleaning member 31 to move on the surface of the filter member 12, that is, the moving direction of the cleaning member 31 is the same as the sliding direction of the mounting member 32. Therefore, the waste collection box 40 and the mounting member 32 can be arranged on opposite sides of the filter box 10 along the sliding direction of the mounting member 32, so that the waste collection box 40 can be located in the moving direction of the cleaning member 31.

[0064] In some embodiments, the cleaning member 31 may also be slidably disposed in the filter box 10 , and the installation member 32 does not need to be disposed, and the cleaning member 31 can also be installed and moved in the filter box 10 .

[0065] The structure of the effluent extraction device 100 is further described below by taking the example that the cleaning member 31 is installed in the filter box 10 through the installation member 32 .

[0066] See also Figure 2 and Figure 3 As shown, the linear moving member 33 is disposed in the filter box 10 and connected to the mounting member 32. The linear moving member 33 is configured to drive the mounting member 32 to slide relative to the filter box 10, so that the linear moving member 33 drives the mounting member 32 to slide in the filter box 10, thereby driving the cleaning member 31 to move on the surface of the filter member 12.

[0067] In some embodiments, the linear moving member 33 can be a screw. The linear moving member 33 (screw) is inserted into the mounting member 32 and is rotatably connected to the mounting member 32. For example, the linear moving member 33 can be rotatably connected to the mounting member 32 through a bearing, and the bearing can be located between the linear moving member 33 and the mounting member 32 in the mounting member 32. The cleaning assembly 30 also includes a driving member 34, at least part of which is located outside the filter box 10. The driving member 34 is sleeved on the circumferential side wall of the linear moving member 33 and is threadedly connected to the linear moving member 33. The driving member 34 is rotatably arranged relative to the filter box 10, and when it is configured to rotate relative to the filter box 10, it can drive the linear moving member 33 to rotate at the same time, and move relative to the filter box 10 along the sliding direction of the mounting member 32 to drive the mounting member 32 to slide relative to the filter box 10. Since the driving member 34 is threadedly connected to the linear moving member 33, and the linear moving member 33 can be a screw and is rotatably connected to the mounting member 32, when the driving member 34 rotates relative to the filter box 10, it can drive the filter box 10 to rotate and convert the rotation of the linear moving member 33 into movement along the sliding direction of the mounting member 32, so that when the mounting member 32 is driven to slide relative to the filter box 10 by the linear moving member 33, the cleaning member 31 can be driven to move on the surface of the filter member 12 by the mounting member 32.

[0068] See also Figure 3 As shown, the driving member 34 may include a turntable 341 and a force-applying portion 342. For example, the force-applying portion 342 may be a columnar structure. The turntable 341 is sleeved on the circumferential side wall of the linear moving member 33 and is threadedly connected to the linear moving member 33, and the force-applying portion 342 is arranged on the turntable 341. The turntable 341 can be used to sleeve the driving member 34 on the linear moving member 33. Through the arrangement of the force-applying portion 342, it is convenient for the user's fingers and the like to act on the force-applying portion 342, and the drive turntable 341 is driven to rotate around the axis of the linear moving member 33, thereby realizing the rotation of the driving member 34 relative to the filter box 10. The axis of the linear moving member 33 is parallel to the sliding direction of the mounting member 32. The force-applying portion 342 may be integrally connected to the turntable 341, or the force-applying portion 342 may also be arranged on the turntable 341 by means of clamping, bonding, etc.

[0069] It should be noted that at least part of the driving member 34 is located outside the filter box 10, that is, part of the driving member 34 can be located outside the filter box 10, or the driving member 34 can also be located entirely outside the filter box 10. When part of the driving member 34 can be located outside the filter box 10, the rotating disk 341 can be located inside the filter box 10, and the force applying part 342 can be located outside the filter box 10. When the driving member 34 is entirely located outside the filter box 10, that is, the rotating disk 341 and the force applying part 342 are both located outside the filter box 10.

[0070] In some embodiments, the linear moving member 33 can also be other structures other than a screw rod. For example, the linear moving member 33 can also be an electric telescopic rod, etc. The electric telescopic rod has a telescopic end and a fixed end, and the telescopic end can be telescopic relative to the fixed end to change the length of the electric telescopic rod. The telescopic end can be connected to the mounting member 32. For example, the telescopic end can be connected to the surface of the mounting member 32 to achieve the connection between the telescopic end and the mounting member 32. Alternatively, the telescopic end can also be inserted into the mounting frame to achieve the connection between the telescopic end and the mounting member 32. In the present application, the connection method between the telescopic end and the mounting member 32 is not particularly limited. When the telescopic end is telescoped relative to the fixed end, it can also drive the mounting member 32 to slide relative to the filter box 10, thereby driving the cleaning member 31 to move on the surface of the filter member 12.

[0071] It should be noted that, since the electric telescopic rod can drive the mounting member 32 to slide relative to the filter box 10 through the extension and retraction of the telescopic end, when the linear moving member 33 is an electric telescopic rod, the cleaning assembly 30 may not need to be provided with a driving member 34.

[0072] The following uses the linear moving member 33 as a screw as an example to further explain the structure of the accumulated liquid extraction device 100.

[0073] See also Figure 1 As shown, the effusion extraction device 100 also includes a liquid suction component 50 and / or a liquid outlet pipe 60. Among them, the liquid suction component 50 includes a needle 51, an infusion tube 52 and an air suction pump 53. At least part of the infusion tube 52 is arranged outside the filter box 10 and is connected to the filter box 10. The needle 51 is arranged at one end of the infusion tube 52 away from the filter box 10. The air suction pump 53 is arranged outside the filter box 10 and is connected to the filter box 10. The needle 51 can be inserted into a certain part of the patient's body (such as the inside of the tumor), and when the air suction pump 53 is running, the air in the filter box 10 can be sucked by the air suction pump 53, and negative pressure is provided in the filter box 10, so that the effusion on the patient's body (such as the inside of the tumor) can be sucked into the filter box 10 through the needle 51 and the infusion tube 52 under the action of negative pressure, and filtered through the filter element 12 to prevent suspended matter from entering the collector 20 through the filter element 12.

[0074] It should be noted that at least part of the infusion tube 52 is disposed outside the filter box 10 , that is, the infusion tube 52 may be partially disposed outside the filter box 10 , or the infusion tube 52 may also be entirely disposed outside the filter box 10 .

[0075] See also Figure 1As shown, both the infusion tube 52 and the suction pump 53 can be arranged on the top cover 11 of the filter box 10. A fourth opening 111 and a fifth opening 112 can be arranged on the top cover 11 of the filter box 10. Among them, the fourth opening 111 corresponds to the infusion tube 52. When the infusion tube 52 is arranged outside the filter box 10, the infusion tube 52 corresponds to the fourth opening 111, so that the infusion tube 52 and the filter box 10 can be connected through the fourth opening 111. A protective box can be provided on the top cover 11 of the filter box 10, and the suction pump 53 is arranged in the protective box, so that the suction pump 53 is fixed on the top cover 11 of the filter box 10 through the protective box (not shown). When the suction pump 53 is arranged outside the filter box 10 through the protective box, the suction pump 53 corresponds to the fifth opening 112, so that the suction pump 53 and the filter box 10 can be connected through the fifth opening 112.

[0076] At least part of the liquid outlet pipe 60 is disposed in the collector 20 and communicated with the collector 20, so that the accumulated fluid in the collector 20 can be discharged from the liquid effusion extraction device 100 through the liquid outlet pipe 60, so that the accumulated fluid in the collector 20 can be used for the subsequent tumor treatment process. In addition, since the collector 20 collects the accumulated fluid filtered by the filter element 12, the liquid outlet pipe 60 can be blocked by suspended matter, so as to further ensure the correct use of the liquid effusion extraction device 100.

[0077] It should be noted that at least a portion of the liquid outlet pipe 60 is disposed on the collector 20 , that is, the liquid outlet pipe 60 may be partially disposed outside the collector 20 , or the liquid outlet pipe 60 may also be entirely disposed outside the collector 20 .

[0078] See also Figure 1 As shown, a control valve 61 may also be provided on the liquid outlet pipe 60 so as to control the opening and closing of the liquid outlet pipe 60 through the control valve 61 .

[0079] In summary, after the effusion extraction device 100 of the embodiment of the present application sucks out the effusion from the patient's body, the effusion enters the filter box 10 and is filtered by the filter element 12, and can be collected in the collector 20. Through the arrangement of the filter element 12 and the cleaning component 30, when there are a lot of suspended matter on the surface of the filter element 12, the driving member 34 can be rotated to drive the linear moving member 33 to move toward the waste collection box 40, and drive the mounting member 32 to slide toward the waste collection box 40 in the filter box 10 at the same time, thereby driving the cleaning member 31 to move on the surface of the filter element 12, and remove the suspended matter on the surface of the filter element 12, so that the suspended matter can be collected in the waste collection box 40, so as to ensure the normal use of the effusion extraction device 100.

[0080] During the use of the effusion extraction device 100, if it is placed directly on the working area of ​​the workbench, after a person touches the effusion extraction device 100, the effusion extraction device 100 may be displaced on the workbench to a certain extent, causing the needle 51 inserted into the patient to fall off or deflect.

[0081] To this end, the effusion extraction device 100 provided in the embodiment of the present application further includes a suction cup assembly 70. Figure 4 As shown, the suction cup assembly 70 includes a suction cup 71, an air outlet pipe 72 and a blocking cover 73. The suction cup 71 is arranged at the bottom of the collector 20, and a compressible cavity is provided on a side of the suction cup 71 away from the collector 20. The air outlet pipe 72 is connected to the cavity, and the blocking cover 73 is detachably blocked in an end of the air outlet pipe 72 away from the suction cup 71.

[0082] When the effusion extraction device 100 needs to be moved to the working area on the workbench to extract effusion, the blocking cover 73 can be sealed on the air outlet pipe 72, so that the side of the suction cup 71 with the cavity contacts the workbench and seals the cavity through the workbench, and then the effusion extraction device 100 is pressed downward to compress the cavity, so that the suction cup 71 is adsorbed on the surface of the workbench with negative pressure, and the effusion extraction device 100 can be fixed in the working area through the suction cup 71 to prevent the effusion extraction device 100 from being displaced on the workbench due to human touch, and to prevent the needle 51 inserted into the patient from falling off or deflecting. In addition, since the blocking cover 73 is detachably blocked at the end of the air outlet pipe 72 away from the suction cup 71, when the effusion extraction device 100 needs to be moved, the blocking cover 73 can be removed from the air outlet pipe 72, so that the pressure difference inside and outside the suction cup 71 is the same, so that the effusion extraction device 100 is in an active state and easy to move.

[0083] It should be noted that the blocking cover 73 can be connected to the air outlet pipe 72 by means of a connecting rope, etc., so as to avoid the blocking cover 73 from being lost and to quickly block the air outlet pipe 72. For example, the connecting rope can include a plastic rope, etc.

[0084] See also Figure 4 As shown, a bottom plate 80 is provided at the bottom of the collector 20. The bottom plate 80 can be fixed to the bottom of the collector 20 by fasteners. A connecting rod 90 is provided on the side of the bottom plate 80 away from the filter box 10, and the connecting rod 90 is connected between the suction cup 71 and the bottom plate 80, so as to fix the suction cup 71 to the bottom of the collector 20 through the connecting rod 90 and the bottom plate 80. The connecting rod 90 can be connected to a connecting plate (not shown) and connected to the bottom plate 80 through the connecting plate. The connecting plate can be connected to the bottom plate 80 by fasteners.

[0085] The number of suction cup assemblies 70 is multiple. For example, the number of suction cup assemblies 70 can be two, three, four, five, six, etc. Multiple suction cup assemblies 70 are correspondingly arranged at different positions on the bottom surface of the collector 20, so that the fixing effect of the effusion extraction device 100 in the working area can be enhanced by the arrangement of multiple suction cup assemblies 70, so that the effusion extraction device 100 is stably fixed in the working area. Exemplarily, multiple suction cup assemblies 70 can be evenly distributed at different positions on the bottom surface of the collector 20 to further enhance the fixing effect of the effusion extraction device 100 in the working area.

[0086] The following is an exemplary description of the use of the effusion extraction device 100 , which does not constitute a limitation on the use of the effusion extraction device 100 .

[0087] When the effusion extraction device 100 is in use, the effusion extraction device 100 is first moved to the working area, and then the effusion extraction device 100 is pressed downward so that the suction cup 71 and the workbench surface are adsorbed, thereby fixing the effusion extraction device 100 in the working area; then, the effusion extraction device 100 is used to extract the effusion from the patient. When there are a lot of suspended matter on the surface of the filter element 12, the driving member 34 is rotated to make the cleaning member 31 move on the surface of the filter element 12 toward the waste collection box 40 to remove the suspended matter on the surface of the filter element 12; after the use of the effusion extraction device 100 is completed, the blocking cover 73 can be removed from the air outlet pipe 72, so that the effusion extraction device 100 is in an active state and is easy to move.

[0088] It should be noted that, if the effusion extraction device 100 needs to be moved during the effusion extraction process, the blocking cover 73 can also be removed from the air outlet pipe 72 .
