[0019] The technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0020] Please refer to Figure 1-12 , the present invention provides a technical solution: a multifunctional tumor drainage device, including a liquid inlet pipe 1, a connection section 2 provided on one side of the liquid inlet pipe 1, and a liquid outlet pipe 3 provided on the connection section 2, further including: A detection element 4, arranged inside the liquid inlet pipe 1, for detecting the flow rate of the liquid inside the liquid inlet pipe 1; An alarm 5, arranged on the liquid inlet pipe 1 and connected to the detection element 4 through a plc control system; A cleaning unit 6, arranged on the connection section 2, for cleaning the inside of the liquid inlet pipe 1; The cleaning unit 6 includes: A cleaning device 61, penetrating through one side of the connection section 2; An adjusting device 62, penetrating through one side of the connection section 2 and perpendicularly arranged to the cleaning device 61.

[0021] It should be noted that during operation, during the tumor treatment process, the liquid inlet pipe 1 is connected to the drainage pipe. Under the action of the negative pressure component, the pleural and peritoneal effusion flows through the liquid inlet pipe 1, then through the connection section 2, and is discharged from the liquid outlet pipe 3. The detection element 4 is provided with a flow sensor at the position where the liquid inlet pipe 1 is connected to the connection section 2 to detect the flow rate of the effusion inside the liquid inlet pipe 1. When the flow rate of the effusion slows down inside the liquid inlet pipe 1 and the liquid outlet pipe 3, the flow sensor will transmit a signal to the plc control system, and the plc control system will turn on the alarm 5 to alert the medical staff that the effusion inside the connection section 2 is congested. Then, at this time, the medical staff adjusts the cleaning device 61 to move the cleaning device 61 into the connection section 2. Then, the moving adjustment device 62 drives the cleaning device 61 to move inside the connection section 2 to clean the viscous waste liquid inside the connection section 2 and dredge the inside of the connection section 2. By setting the detection element 4, the flow rate of the liquid inside the liquid inlet pipe 1 can be monitored in real time. When the flow rate is abnormal, the alarm 5 will immediately respond to remind the medical staff to deal with it in time. The medical staff moves the adjustment device 62 to drive the cleaning device 61 to move inside the connection section 2 to clean and dredge the viscous waste liquid inside the connection section 2. With simple operations, the cleaning of the delivery pipe can be realized, greatly improving the operation convenience and effectively reducing the risk of blockage of the drainage pipe during the drainage process, providing a safer and more efficient drainage treatment plan for tumor patients.

[0022] In one embodiment, a fixing ring 21 is provided on the side of the connection section 2 away from the liquid inlet pipe 1. The detection element 4 is inserted through the fixing ring 21. A connection pipe 22 is provided on the side of the fixing ring 21 connected to the connection section 2. A sealing ring 23 is provided inside the connection pipe 22. An installation cavity 2201 for placing the cleaning device 61 is provided between the connection pipe 22 and the sealing ring 23. The sealing ring 23 is made of rubber. The detection element 4 passes through the sealing ring 23. A sealing ring 24 is provided on the side of the connection section 2 opposite to the liquid outlet pipe 3.

[0023] With such a design, referring to Figure 4 and Figure 5 , the sealing ring 23 is made of rubber and has good elasticity, ductility and corrosion resistance, which can effectively prevent liquid leakage, ensure the stable operation of the system, and can facilitate the cleaning device 61 to shuttle on both sides of the sealing ring 23. When the effusion flows normally inside the liquid inlet pipe 1 and the liquid outlet pipe 3, the cleaning device 61 is accommodated in the installation cavity 2201, which can reduce the occupied space of the cleaning device 61 inside the connection section 2, thus facilitating the flow of the effusion inside the connection section 2.

[0024] In one embodiment, the cleaning device 61 includes a push rod 611 slidably disposed on the fixed ring 21 and passing through the connecting section 2 and the sealing ring 23, a push block 612 fixed to the side of the push rod 611 away from the connecting section 2, a fixing bracket 613 fixed to the other side of the push rod 611, and a cleaning member disposed on the fixing bracket 613 for cleaning impurities inside the connecting section 2. The cleaning member is disposed inside the installation cavity 2201, and a moving groove 211 for the movement of the push rod 611 is formed on the fixed ring 21.

[0025] With such a design, referring to Figure 5 , push the push rod 611 towards one side of the connecting section 2, then make the fixing bracket 613 drive the cleaning member to pass out from inside the sealing ring 23, and then move into the inside of the connecting section 2. Then, after moving the fixing bracket 613 to the set position, stop moving the push rod 611.

[0026] In one embodiment, the cleaning member includes a support ring 614 disposed on the fixing bracket 613 and cleaning blades 615 fixed to the support ring 614. A slider 6131 slidably connected to the support ring 614 is disposed at the lower end of the fixing bracket 613. A sliding groove 61401 for the movement of the slider 6131 is formed on the support ring 614, and a gear 616 is disposed on the support ring 614.

[0027] With such a design, referring to Figure 4-12 , the fixing bracket 613 pushes the support ring 614 to move on the detection element 4. Then, when the cleaning blades 615 move to the set position, the moving adjustment device 62 drives the support ring 614 to rotate on the detection element 4, so that the cleaning blades 615 rotate inside the connecting section 2. Then, the support ring 614 rotates along the slider 6131 at the lower end of the fixing bracket 613, and the slider 6131 moves in the sliding groove 61401 on the support ring 614, which can stir and separate the relatively viscous accumulated liquid inside the connecting section 2, thereby dredging the mucus accumulated inside the connecting section 2.

[0028] In one embodiment, the adjustment device 62 includes an adjustment rod 621 passing through the sealing ring 24, a mounting plate 622 fixed to the side of the adjustment rod 621 inside the connecting section 2, and a rack 623 fixed to the lower end of the mounting plate 622. The rack 623 is meshed with the gear 616.

[0029] With such a design, referring to Figure 5-9 , push the adjustment rod 621 to move in the sealing ring 24, then make the mounting plate 622 drive the rack 623 to move into the inside of the connecting section 2. Then, the rack 623 meshes with the gear 616, thereby driving the gear 616 to rotate, making the support ring 614 rotate on the detection element 4, and driving the cleaning blades 615 to stir and separate the mucus.

[0030] In one embodiment, a pull ring 626 is provided on one side of the adjusting rod 621 outside the connecting section 2. An extrusion plate 624 is provided between the adjusting rod 621 and the sealing ring 24. A first elastic member 625 is sleeved between the adjusting rod 621 and the extrusion plate 624. The first elastic member 625 is made of a spring or an elastic pad with damping.

[0031] With such a design, referring to Figure 8 , when the adjusting rod 621 moves towards the inside of the connecting section 2, the extrusion plate 624 squeezes the first elastic member 625. When the medical staff releases the pull ring 626, the first elastic member 625 drives the extrusion plate 624 to reset, thereby causing the rack 623 to mesh with the gear 616 in the reverse direction, and further causing the support ring 614 to rotate clockwise and counterclockwise alternately on the detection element 4, further improving the cleaning efficiency of the liquid accumulation congested inside the connecting section 2.

[0032] In one embodiment, the cleaning unit 6 further includes a fixing device 63 provided on the fixing ring 21 for fixing the pushing block 612. A fixing groove 61201 is provided at the position of the pushing block 612 corresponding to the fixing device 63.

[0033] With such a design, referring to Figure 10 and Figure 11 , when the pushing block 612 moves to the set position, the fixing device 63 is snapped and fixed in the fixing groove 61201 on the pushing block 612, fixing the pushing block 612 to the fixing ring 21, thereby fixing the position of the gear 616 inside the connecting section 2 and improving the installation stability of the entire cleaning device 61.

[0034] In one embodiment, the fixing device 63 includes a support plate 631 fixed on the fixing ring 21, a fixing rod 632 passing through the support plate 631, a limiting plate 633 fixed on the side of the fixing rod 632 away from the pushing block 612, and a fixing block 634 fixed on the side of the fixing rod 632 close to the pushing block 612. A second elastic member 635 is sleeved between the fixing rod 632 and the support plate 631. The fixing block 634 is inserted and fixed inside the fixing groove 61201. The second elastic member 635 is made of a spring or an elastic pad with damping.

[0035] With such a design, referring to Figure 10 and Figure 12When the pushing block 612 contacts the fixed block 634, the pushing block 612 can push the fixed block 634 to move towards one side of the support plate 631, so that the fixed block 634 squeezes the second elastic member 635. When the fixed block 634 moves to the position of the fixing groove 61201, the second elastic member 635 drives the fixed block 634 to move into the fixing groove 61201, fixing the pushing block 612, so that the gear 616 can be stably installed inside the connecting section 2. Furthermore, when the rack 623 meshes with the gear 616, the gear 616 will not shift, thereby improving the rotation stability of the cleaning blade 615 and enhancing the cleaning efficiency of the cleaning blade 615 for the liquid accumulation.

[0036] In one embodiment, a placement groove 63101 for the movement of the pushing block 612 is formed on the support plate 631.

[0037] With this design, referring to Figure 10 , the placement groove 63101 can accurately guide the movement path of the pushing block 612, ensuring that it moves along a predetermined trajectory, and improving the stability and accuracy of the movement of the pushing block 612.

[0038] In one embodiment, the fixed block 634 is wedge-shaped.

[0039] With this design, referring to Figure 12 , the wedge-shaped setting of the fixed block 634 can directly push the fixed block 634 to move towards the side close to the support plate 631 when the fixed block 634 contacts the pushing block 612, making the pushing block 612 drive the fixed block 634 to move more smoothly.

[0040] In addition, if the description involves "first", "second", etc. in the embodiment, such descriptions of "first", "second", etc. are only for descriptive purposes and should not be construed as indicating or implying their relative importance to the specification or implicitly indicating the quantity of the indicated technical features. Thus, the features defined with "first", "second" may explicitly or implicitly include at least one such feature.
