Description

Technical Field

[0001] This invention relates to the field of medical device technology, and in particular to a drainage device for tumor care. Background Technology

[0002] During the progression of malignant tumors, effusion often occurs in body cavities. This effusion can compress organs, affect respiratory and circulatory functions, severely reduce the patient's quality of life, and even endanger life. Therefore, tumor effusion drainage devices have become key instruments in palliative care of tumors. Existing tumor effusion drainage devices typically include a puncture and catheterization assembly, a drainage catheter, a flow control mechanism, an anti-backflow mechanism, and an effusion storage container. The working principle is to insert the distal end of the drainage catheter into the effusion cavity through puncture and catheterization. Relying on the pressure difference between the body cavity and the outside, the effusion flows along the drainage catheter into the storage container, thereby draining the effusion.

[0003] In actual clinical applications, malignant effusions contain a large number of tumor tissue debris, fibrin flocculents and other impurities. These impurities will adhere to the inner wall of the drainage tube as the effusion flows. After long-term accumulation, they will gradually form a blockage, which will reduce the flow cross-sectional area of ​​the drainage tube. In severe cases, the drainage channel will be completely blocked, resulting in drainage failure.

[0004] In existing technologies, the main methods for clearing blocked drainage tubes are manual external flushing or guide wire unblocking. Manual flushing cannot accurately target tissue debris attached to the inner wall of the drainage tube, resulting in poor unblocking effect and low efficiency, requiring frequent operation by medical staff. Guide wire unblocking can easily damage the inner wall of the drainage tube, which can lead to the drainage tube breaking over time. Summary of the Invention

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments.

[0030] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0031] Many specific details are set forth in the following description in order to provide a full understanding of the invention. However, the invention may also be practiced in other ways different from those described herein, and those skilled in the art can make similar extensions without departing from the spirit of the invention. Therefore, the invention is not limited to the specific embodiments disclosed below.

[0032] Secondly, the term "one embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single or selective embodiment that is mutually exclusive with other embodiments.

[0033] Example 1, referring to Figure 1 , Figures 5-7 This is the first embodiment of the present invention, which provides a drainage device for tumor care. The drainage device for tumor care includes a drainage tube 11, the water inlet of the drainage tube 11 is connected to the puncture drainage tube, and a collection bottle 12 is provided at the bottom end of the drainage tube 11. The drainage tube 11 drains the fluid into the collection bottle 12 and stores the fluid. The drainage tube 11 is provided with a flow control mechanism and an anti-backflow mechanism. This is prior art, and this solution will not be described in detail. Moreover, those skilled in the art can clearly understand the working principle.

[0034] It also includes a connector 13 fixed to the drainage tube 11. There are two connectors 13, located at the upper and lower ends of the drainage tube 11 respectively. The connectors 13 are fixed to the drainage tube 11 by crimping. The connectors 13 are made of rigid plastic.

[0035] The unblocking component 2 is installed inside the drainage pipe 11 and includes an unblocking part 21. The unblocking part 21 includes a movable column 211 located inside the drainage pipe 11. The top of the movable column 211 is arc-shaped and the inside is hollow. It ensures that when the movable column 211 flows upward inside the drainage pipe 11, it will not cause the accumulated liquid to flow back.

[0036] A cleaning cloth 212 is fixed to the outside of the movable column 211. The cleaning cloth 212 is made of waterproof material. A movable sleeve 213 is fitted on the outside of the movable column 211. A support rod 214 is fixed to the inside of the cleaning cloth 212. There are multiple support rods 214, which are evenly distributed in a ring on the outside of the movable column 211. The support rods 214 are used to support the cleaning cloth 212. The top of the support rod 214 is hinged to the movable column 211. A connecting rod 215 is hinged to the outside of the movable sleeve 213. The number of connecting rods 215 corresponds to the number of support rods 214. The top of the connecting rod 215 is hinged to the support rod 214.

[0037] When the movable sleeve 213 moves upward, it pushes the support rod 214 upward through the connecting rod 215. When the support rod 214 rotates upward, it will open the cleaning cloth 212 into the shape of an open umbrella and taut the cleaning cloth 212. At this time, the outer ring of the cleaning cloth 212 will contact the inner wall of the drainage tube 11. When the movable column 211 flows down, it will drive the cleaning cloth 212 to clean the inner wall of the drainage tube 11. It can accurately act on the blockage area, thoroughly remove the tissue debris attached to the inner wall, and apply a pushing force to the tissue debris, so that the tissue debris is discharged into the collection bottle 12. During the cleaning process, there is no need to stop the drainage work, and the drainage work can be kept stable. The taut flexible cleaning cloth 212 has sufficient pushing force on the tissue debris, but will not damage the inside of the drainage tube 11.

[0038] When the movable sleeve 213 moves downward, it will pull the support rod 214 downward through the connecting rod 215, and the support rod 214 will drive the cleaning cloth 212 to retract inward, thereby preventing the liquid from flowing back when the movable column 211 moves upward against the current. In addition, an anti-backflow mechanism can be installed above the upper end of the drain cleaner 21 to further prevent the liquid from flowing back.

[0039] Example 2, refer to Figures 2-4 This is the second embodiment of the present invention, which is based on the previous embodiment.

[0040] Specifically, the unblocking component 2 also includes a movable component 22. There are two sets of movable components 22, located on the outside of the upper and lower connectors 13 respectively. The movable component 22 includes a fixed frame 221 located on the outside of the connector 13. There are two fixed frames 221 in one set of movable components 22. The fixed frame 221 is half a side. The two fixed frames 221 are combined and spliced ​​on the outside of the connector 13 and fixed by bolts.

[0041] A roller 222 is rotatably connected inside the fixed frame 221. A connecting plate 223 is fixed inside the movable sleeve 213. A sliding groove is provided on the movable column 211. The connecting plate 223 passes through the sliding groove and is slidably connected to the sliding groove. A pull rope 224 is fixed on the connecting plate 223. One end of the pull rope 224 passes through the connector 13 and is fixed to the roller 222.

[0042] A drive motor 225 is fixed on one side of the fixed frame 221, and the output shaft of the drive motor 225 is fixed to the reel 222.

[0043] When the upper drive motor 225 drives the upper reel 222 to rotate, the reel 222 will wind up the upper pull rope 224, and the pull rope 224 will drive the connecting plate 223 to move upward, and then the connecting plate 223 will drive the movable column 211 to move upward. Similarly, when the lower drive motor 225 starts, it will drive the movable column 211 to move downward.

[0044] A protrusion 226 is fixed on the outside of the movable column 211, and a limiting hole 213-1 is opened on the movable sleeve 213. The protrusion 226 engages with the limiting hole 213-1 to lock the position of the movable sleeve 213.

[0045] The protrusion 226 is spherical and there are two of them. It is fixed vertically on one side of the movable column 211. The spherical shape of the protrusion 226 can prevent the movable sleeve 213 from moving due to the resistance of the accumulated liquid when it is locked. Moreover, when subjected to a greater pulling force from the pull rope 224, it can counteract the friction between the protrusion 226 and the limiting hole 213-1 and prevent it from moving.

[0046] There are two limit rods 227 fixed inside the connector 13. The limit rods 227 are fixed in the two connectors 13 respectively. The limit rods 227 are used to block the movement of the movable column 211. When the movable column 211 moves into the upper connector 13, it will contact the limit rod 227 and be blocked by the limit rod 227 and cannot move upward. At this time, the pull rope 224 continues to be wound. The pull rope 224 will pull the connecting plate 223 to move upward. The connecting plate 223 will drive the movable sleeve 213 to move upward. Thus, the movable sleeve 213 can drive the connecting rod 215 and the support rod 214 to unfold the cleaning cloth 212. After the movable sleeve 213 stops moving, the limit hole 213-1 will engage with another protrusion 226.

[0047] Similarly, when the movable column 211 moves into the lower connector 13 and is blocked by the limit rod 227, the movable sleeve 213 can be pulled downward by the pull rope 224, and the cleaning cloth 212 can be retracted inward.

[0048] Example 3, referring to Figure 3 and Figure 4 This is the third embodiment of the present invention, which is based on the first two embodiments.

[0049] Specifically, a cleaning ring 23 is fixed inside the fixed frame 221. The cleaning ring 23 is semi-circular and is fixed to the inner wall of the two fixed frames 221 respectively. The inner side of the cleaning ring 23 is inclined and is used to clean the accumulated liquid attached to the outside of the pull rope 224.

[0050] A collection frame 24 is fixed inside the fixed frame 221 and below the cleaning ring 23. The collection frame 24 is used to collect the accumulated liquid after cleaning. The collection frame 24 is through-type from top to bottom. A collection bag is installed inside the collection frame 24. The accumulated liquid scraped off by the cleaning ring 23 will fall into the collection frame 24 and be discharged into the collection bag through the collection frame 24. In this way, only the collection bag needs to be replaced.

[0051] A retaining ring 228 is fixed inside the fixed frame 221, and a slot 13-1 is provided on the connector 13. The retaining ring 228 engages with the slot 13-1, and the two work together to position the fixed frame 221.

[0052] In this solution, all structures of the drainage tube 11, the unblocking component 21, and the pull rope 224 can be used as disposable items for only one patient and do not need to be reused. The structure of the moving component 22 is external, and it can be reused after disinfection and cleaning.

[0053] When it is necessary to clear the inside of the drainage tube 11, the drive motor 225 above is started to drive the upper roller 222 to rotate. The roller 222 will then wind up the upper pull rope 224, and the pull rope 224 will drive the connecting plate 223 to move upward. In turn, the connecting plate 223 will drive the movable column 211 to move upward, so that the movable column 211 moves slowly upward.

[0054] When the movable column 211 moves into the upper connector 13, it will contact the limiting rod 227 and be unable to move upward due to the obstruction of the limiting rod 227. At this time, continue to wind up the pull rope 224, and the pull rope 224 will pull the connecting plate 223 to move upward, and through the connecting plate 223, drive the movable sleeve 213 to move upward. When the support rod 214 rotates upward, it will open the cleaning cloth 212 into the shape of an open umbrella and taut the cleaning cloth 212. At this time, the outer ring of the cleaning cloth 212 will contact the inner wall of the drainage tube 11.

[0055] At this time, the drive motor 225 below is activated, and the movable column 211 is moved downward through the pull rope 224 below. When the movable column 211 flows down, it will drive the cleaning cloth 212 to clean the inner wall of the drainage tube 11. It can accurately act on the blockage area, thoroughly remove the tissue debris attached to the inner wall, and apply a pushing force to the tissue debris, so that the tissue debris is discharged into the collection bottle 12. During the cleaning process, there is no need to stop the drainage work, and the drainage work can be kept stable. The taut flexible cleaning cloth 212 has sufficient pushing force on the tissue debris, but will not damage the inside of the drainage tube 11.

[0056] When the movable column 211 moves into the lower connector 13 and is obstructed by the limit rod 227, the movable sleeve 213 is pulled downward by the pull rope 224. When the movable sleeve 213 moves downward, the support rod 214 is pulled downward by the connecting rod 215, and the cleaning cloth 212 is pulled inward by the support rod 214. This prevents the cleaning cloth 212 from causing backflow of liquid when the movable column 211 moves upward against the current flow, and keeps the movable column 211 in its current position to prevent the cleaning cloth 212 from obstructing the smooth discharge of liquid.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention and are not intended to limit it. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention, and all such modifications or substitutions should be covered within the scope of the claims of the present invention.
