Description

Technical Field

[0001] This utility model relates to the field of fluid accumulation treatment technology, specifically a fluid accumulation treatment device for interventional oncology. Background Technology

[0002] Tumor interventional effusion treatment devices are used for the extraction and collection of effusions. However, existing devices have certain drawbacks. For example, the tumor effusion aspirator described in announcement number CN221672867U includes an effusion tank, a trolley frame fixedly installed at the bottom of the effusion tank, an audible and visual alarm fixedly installed at the rear of the trolley frame, a controller fixedly installed on the top right side of the trolley frame, a negative pressure pump fixedly installed on the outside of the effusion tank, a tank cover on the top of the effusion tank, a connecting tube penetrating the top surface of the tank cover, a puncture needle seat fixedly installed at the end of the connecting tube away from the tank cover, and a puncture needle inserted into the end of the puncture needle seat away from the connecting tube.

[0003] Although the above-mentioned device can provide a liquid level alarm to ensure that the negative pressure pump will not enter the system during pumping, when the user moves the device, the liquid level will shake violently due to inertia during the initial pushing and sudden braking. This will cause some liquid to splash onto the negative pressure pump, affecting its normal operation later. Utility Model Content

[0004] The purpose of this invention is to provide a device for treating fluid accumulation in interventional oncology departments, in order to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A device for treating effusion in interventional oncology includes a base plate, an effusion bucket that is snapped onto the upper surface of the base plate, an inverted conical funnel that is threaded onto the upper surface of the effusion bucket, and a top cover that is threaded onto the upper surface of the inverted conical funnel.

[0007] The liquid collection tank has a connecting frame inside, and a float ball is fixedly connected to the outer surface of the connecting frame. An air extraction module is snapped onto the upper surface of the cover. The air extraction module includes a mounting plate, a negative pressure pump, and a filter box. The mounting plate is snapped onto the upper surface of the cover, the negative pressure pump is fixedly connected to the upper surface of the mounting plate, and the filter box is fixedly connected to the upper surface of the mounting plate. The output end of the negative pressure pump is connected to the liquid collection tank, and the output end of the negative pressure pump is connected to the filter box.

[0008] A controller is fixedly connected to the upper surface of the mounting plate, and a storage box is fixedly connected to the upper surface of the mounting plate. A limit module is provided on the upper surface of the cover. The limit module includes a fixing seat, which is fixedly connected to the upper surface of the cover. A limit tube is embedded and fixedly connected to the upper surface of the fixing seat. There are three limit tubes, and a puncture needle with a tube is embedded inside one of the limit tubes.

[0009] Furthermore, a limiting cylinder is fixedly connected to the upper surface of the base plate, and the liquid collection tank is engaged with the base plate through the limiting cylinder.

[0010] Furthermore, an installation block is fixedly connected to the outer surface of the liquid collection tank near the upper end, an audible and visual alarm is fixedly connected to the upper surface of the installation block, and a liquid sensing switch is embedded in the lower surface of the installation block.

[0011] Furthermore, the upper surface of the cover is fixedly connected to a limiting strip, and the upper surface of the mounting plate is provided with a limiting groove, the limiting groove and the limiting strip being matched.

[0012] Furthermore, the air extraction module also includes a cover and a filter screen, with the cover nested and connected to the upper end of the filter box, and the filter screen embedded and movably connected to the inside of the filter box.

[0013] Furthermore, the limiting module also includes a nested cover, a fastening knob, and a lower pressure seat. The nested cover is nested and connected to the upper ends of the other two limiting tubes. The fastening knob is threaded to the outer surface of the limiting tube. The lower pressure seat is embedded and movably connected to the lower surface of the fixed seat. An adjusting bolt is rotatably connected to the upper surface of the lower pressure seat.

[0014] Furthermore, the adjusting bolt and the fixed seat are threadedly connected, and the lower pressure seat is in contact with the mounting plate.

[0015] Compared with the prior art, the beneficial effects of this utility model are:

[0016] 1. The connecting frame rises with the float. Placing the connecting frame on the liquid surface can be a way to suppress liquid surface sloshing and reduce the instability of the liquid surface. The inverted cone design blocks most of the splashed liquid, further preventing liquid from splashing to the negative pressure pump position and ensuring the normal use of the device. For some odorous accumulated liquid, the air outlet of the negative pressure pump is connected to the filter box, and the filter box is used with a filter screen to filter the odor.

[0017] 2. After removing the nested cover, multiple puncture needles with tubes can be installed, facilitating the simultaneous use of multiple puncture needles with tubes. Turn the adjusting bolt, and under the push of the thread, the lower pressure seat in contact with the mounting plate rises, causing the upper surface of the mounting plate to lose its external limit. Then, the mounting plate can be moved upward along the limit strip, which will separate the limit groove and the limit strip, allowing the air extraction module, controller, and storage box to be removed for later maintenance of the air extraction module.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figure 1-4 In this embodiment of the utility model, a fluid collection treatment device for interventional oncology includes a base plate 1, a fluid collection tank 2 is snapped onto the upper surface of the base plate 1, an inverted conical bucket 3 is threaded onto the upper surface of the fluid collection tank 2, and an upper cover 4 is threaded onto the upper surface of the inverted conical bucket 3.

[0025] Inside the liquid collection tank 2, there is a connecting frame 10. A float ball 1001 is fixedly connected to the outer surface of the connecting frame 10. An air extraction module 5 is snapped onto the upper surface of the cover 4. The air extraction module 5 includes a mounting plate 501, a negative pressure pump 506, and a filter box 503. The mounting plate 501 is snapped onto the upper surface of the cover 4. The negative pressure pump 506 is fixedly connected to the upper surface of the mounting plate 501. The filter box 503 is fixedly connected to the upper surface of the mounting plate 501. The output end of the negative pressure pump 506 is connected to the liquid collection tank 2. The output end of the negative pressure pump 506 is connected to the filter box 503.

[0026] A controller 6 is fixedly connected to the upper surface of the mounting plate 501, and a storage box 7 is fixedly connected to the upper surface of the mounting plate 501. A limit module 8 is provided on the upper surface of the cover 4. The limit module 8 includes a fixing seat 801, which is fixedly connected to the upper surface of the cover 4. A limit tube 802 is embedded and fixedly connected to the upper surface of the fixing seat 801. There are three limit tubes 802, and a puncture needle 9 with a tube is embedded inside one of the limit tubes 802.

[0027] Specifically, the effusion tank 2 is directly inserted into the limiting tube 101, facilitating the later removal of the effusion tank 2. The audible and visual alarm 202, liquid sensor switch 203, and controller 6 are electrically connected to sense the liquid level inside the effusion tank 2, preventing excessive liquid collection and affecting the normal use of the device. During use, the user moves the effusion tank 2 by pushing it with the base plate 1, moving the device into the ward, and starts the negative pressure pump 506. The negative pressure pump 506 creates a negative pressure state inside the effusion tank 2, generating suction at the end of the puncture needle 9, which can then extract the effusion. During use, the puncture needle 9, in conjunction with the limiting tube 802, is connected to the effusion tank 2. There are three limiting tubes 802, so after removing the nesting cover 803, multiple puncture needles 9 can be installed, facilitating the simultaneous use of multiple puncture needles 9. Rotating the fastening knob 804 can compress the connection position between the puncture needle 9 and the fastening knob 804, sealing the puncture needle 9.

[0028] Example 1

[0029] like Figure 1-4 As shown, a limiting cylinder 101 is fixedly connected to the upper surface of the base plate 1, and the liquid collection tank 2 is engaged with the base plate 1 through the limiting cylinder 101. An installation block 201 is fixedly connected to the outer surface of the liquid collection tank 2 near the upper end. An audible and visual alarm 202 is fixedly connected to the upper surface of the installation block 201, and a liquid sensor switch 203 is embedded in the lower surface of the installation block 201.

[0030] In this embodiment, the effusion tank 2 is directly inserted into the limiting cylinder 101, which facilitates the later removal of the effusion tank 2. The audible and visual alarm 202, the liquid sensing switch 203, and the controller 6 are electrically connected to sense the liquid level inside the effusion tank 2, preventing excessive effusion collection and affecting the normal use of the device. When in use, the user pushes the effusion tank 2 through the base plate 1 to move the device into the ward, and starts the negative pressure pump 506. The negative pressure pump 506 puts the effusion tank 2 into a negative pressure state, causing the end of the puncture needle 9 with tube to generate suction, which can then extract the effusion.

[0031] As the liquid level inside the collection tank 2 rises, the connecting frame 10 rises in conjunction with the float 1001. Placing the connecting frame 10 on the liquid surface can serve as a method to suppress liquid surface sloshing, reduce liquid surface instability, and prevent liquid from splashing onto the suction end of the negative pressure pump 506 when the user moves the device due to violent liquid surface sloshing. Furthermore, the design of the inverted conical bucket 3 blocks most of the splashed liquid, further preventing liquid from splashing onto the negative pressure pump 506 and ensuring the normal operation of the device.

[0032] like Figure 1-4 As shown, the upper surface of the cover 4 is fixedly connected to a limiting strip 401, and the upper surface of the mounting plate 501 is provided with a limiting groove 502. The limiting groove 502 and the limiting strip 401 are matched. The limiting module 8 also includes a nested cover 803, a fastening knob 804 and a lower pressure seat 805. The nested cover 803 is nested and connected to the upper end of the other two limiting tubes 802. The fastening knob 804 is threaded to the outer surface of the limiting tube 802. The lower pressure seat 805 is embedded and movably connected to the lower surface of the fixed seat 801. The upper surface of the lower pressure seat 805 is rotatably connected to an adjusting bolt 806. The adjusting bolt 806 and the fixed seat 801 are threadedly connected. The lower pressure seat 805 is in contact with the mounting plate 501.

[0033] In this embodiment, during use, the cannulated puncture needle 9 is connected to the limiting tube 802 and the liquid collection tank 2. There are three limiting tubes 802. Therefore, after removing the nesting cover 803, multiple cannulated puncture needles 9 can be installed, which facilitates the simultaneous use of multiple cannulated puncture needles 9. Rotating the fastening knob 804 can squeeze the connection position between the cannulated puncture needle 9 and the fastening knob 804 to seal the cannulated puncture needle 9.

[0034] When disassembling the vacuum module 5, rotate the adjusting bolt 806. Under the push of the thread, the lower pressure seat 805 in contact with the mounting plate 501 rises, so that the upper surface of the mounting plate 501 loses its external limit. Then, the mounting plate 501 can be moved upward along the limit strip 401, so that the limit groove 502 and the limit strip 401 can be separated, and the vacuum module 5, controller 6 and storage box 7 can be taken out for later maintenance of the vacuum module 5. In addition, the storage box 7 is used to place items.

[0035] Example 2

[0036] Based on Example 1, in order to overcome the problem of inconvenience in treating exhaust gas in Example 1.

[0037] like Figure 1-4 As shown, the air extraction module 5 also includes a cover 504 and a filter screen 505. The cover 504 is nested and connected to the upper end of the filter box 503, and the filter screen 505 is embedded and movably connected to the inside of the filter box 503.

[0038] In this embodiment, for some odorous accumulated liquid, the outlet of the negative pressure pump 506 is connected to the filter box 503, and the filter box 503 works with the filter screen 505 to filter the odor, wherein the filter screen 505 is an activated carbon filter screen.

[0039] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0040] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
