[0001] This utility model relates to the field of medical device technology, and more specifically, to a tumor drainage device. Background Technology
[0002] Puncture drainage is a common clinical method for treating tumor fluid accumulation. It involves inserting a catheter to drain the fluid from the body and relieve symptoms.
[0003] Chinese patent CN217645605U discloses a drainage device for oncologists, including a storage tank, a drainage tube, a puncture needle, and a negative pressure connecting tube. One end of the drainage tube is connected to the storage tank and extends into the storage tank, while the other end of the drainage tube is fixed with a puncture needle. However, this device only drains fluid through a single drainage tube. Tumor fluid may contain the patient's blood. During use, the blood in the fluid is prone to coagulate and form a thrombus in the later part of the drainage tube, causing blockage. Currently, medical staff usually need to manually squeeze out the thrombus blocking the tube, which takes time and interrupts the drainage process, thus affecting treatment efficiency. Utility Model Content
[0004] This invention provides a tumor fluid drainage device that solves the technical problem in the prior art where the drainage process is interrupted when the rear section of the drainage tube is blocked by a thrombus.
[0005] In view of the above problems, the technical solution proposed by this utility model is as follows:
[0006] A tumor fluid drainage device includes a drainage tube, a puncture needle, and a collection tank. The device also includes a set of hollow spherical shells with three sets of openings arranged on the left, center, and right sides. The rear end of the drainage tube is connected to the opening located in the center position. A first branch tube and a second branch tube are connected to the openings located on the left and right sides, respectively. Inside the hollow spherical shells, a spherical core is provided that fits against its inner wall. Two sets of interconnected water guide holes are opened on the spherical core, the distance between the two sets of water guide holes being equal to the distance between adjacent openings. A rotating rod is rotatably connected to the top of the hollow spherical shells, one end of which extends into the interior of the hollow spherical shells and is fixedly connected to the top of the spherical core. The rear ends of both the first and second branch tubes are connected to the collection tank. A suction pump is provided on one side of the collection tank, and the suction pump is connected to a pump tube extending into the top of the inner cavity of the collection tank.
[0007] Furthermore, the top of the drainage tube is provided with three sets of directional lines, the positions of the three sets of directional lines are aligned with the positions of the three sets of openings, and the surface of the rotating rod is connected with two sets of directional needles, the positions of the two sets of directional needles are aligned with the two sets of water guide holes.
[0008] Furthermore, the top of the rotating rod extends above the hollow spherical shell and is fixedly connected to a handle, allowing medical personnel to easily rotate the rotating rod left and right by gripping the handle.
[0009] Furthermore, several sets of medical tape are connected to the front end of the drainage tube near the puncture needle.
[0010] Furthermore, the top of the liquid collection tank is provided with two sets of threaded ports, and the rear ends of the first branch pipe and the second branch pipe are rotatably connected with threaded caps that are threadedly engaged with the threaded ports.
[0011] Furthermore, a transparent observation window is provided on the outer wall of the liquid collection tank, and scale lines are distributed on the surface of the transparent observation window.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: During the drainage process, the tumor fluid flows out of the hollow spherical shell and enters the interior of the collection tank through the first branch pipe. When the first branch pipe becomes blocked, the fluid flowing out of the hollow spherical shell can be controlled to rotate and enter the interior of the collection tank through the second branch pipe. Medical staff can squeeze and clear the first branch pipe, and the drainage can continue without interruption during the clearing process, thus ensuring the efficiency of treatment.

[0021] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.
[0022] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the claimed invention, but merely to illustrate selected embodiments of the invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without inventive effort are within the scope of protection of the present invention.
[0023] Please see Figure 1-6A tumor fluid drainage device includes a drainage tube 1, a puncture needle 2, and a collection tank 3. The puncture needle 2 is connected to the front end of the drainage tube 1 and can be inserted into the tumor fluid accumulation site in the patient's body to introduce the fluid into the drainage tube 1. The tumor fluid drainage device also includes a set of hollow spherical shells 4, with three sets of openings 5 arranged on the left, middle, and right sides. The rear end of the drainage tube 1 is connected to the opening 5 located in the middle position. The openings 5 located on the left and right sides are respectively connected to a first branch tube 6 and a second branch tube 7. The hollow spherical shell 4 also has a spherical core 8 that fits against its inner wall. The spherical core 8 has two sets of interconnected water guiding holes 9. The distance between the two sets of water guiding holes 9 is the same as the distance between two adjacent sets of openings 5. A rotating rod 10 is rotatably connected to the top of the hollow spherical shell 4. One end of the rotating rod 10 extends into the interior of the hollow spherical shell 4 and is fixedly connected to the top of the spherical core 8. When the user rotates the rotating rod 10, the spherical core 8 inside the hollow spherical shell 4 can rotate left and right. This allows the two sets of water guide holes 9 on the spherical core 8 to be aligned with the openings 5 located on the left and middle positions, or aligned with the openings 5 located on the right and middle positions. The rear ends of the first branch pipe 6 and the second branch pipe 7 are both connected to the liquid collection tank 3. A vacuum pump 11 is provided on one side of the liquid collection tank 3. The vacuum pump 11 is connected to a pump pipe 12 that extends into the top of the inner cavity of the liquid collection tank 3. The vacuum pump 11 can evacuate the inner cavity of the liquid collection tank 3, thereby making the inner cavity of the liquid collection tank 3 a negative pressure state.
[0024] During use, the puncture needle 2 is inserted into the tumor fluid accumulation site in the patient's body. At this time, the two sets of water guide holes 9 on the core 8 are aligned with the openings 5 located on the left and middle of the hollow spherical shell 4, respectively. The suction pump 11 is then activated, creating a negative pressure inside the collection tank 3. Under this negative pressure, the tumor fluid is drawn from the puncture needle 2 into the drainage tube 1. The fluid in the drainage tube 1 flows into the hollow spherical shell 4 from the opening 5 in the middle of the shell, and flows out from the opening 5 on the left side of the shell 4 under the guidance of the two sets of water guide holes 9 on the core 8. The fluid flowing out of the hollow spherical shell 4 from the opening 5 enters the collection tank 3 through the first branch tube 6 and is collected in the collection tank 3. Since both the first branch tube 6 and the second branch tube 7 are located at the rear, when... When blood clots in the accumulated fluid block the first branch tube 6, medical staff can rotate the lever 10 to rotate the two sets of water guide holes 9 on the ball core 8 to align with the openings 5 located in the middle and right side of the hollow spherical shell 4, respectively. At this time, the accumulated fluid drawn into the drainage tube 1 through the puncture needle 2 will flow into the hollow spherical shell 4 from the opening 5 in the middle position and out from the opening 5 on the right side of the hollow spherical shell 4 under the guidance of the two sets of water guide holes 9 on the ball core 8. The accumulated fluid flowing out of the hollow spherical shell 4 will then enter the inside of the collection tank 3 through the second branch tube 7. Medical staff can then squeeze and clear the first branch tube 6. During the clearing process, the drainage process can continue without interruption, thus ensuring the efficiency of treatment.
[0025] For further details, please refer to Figure 1 , Figure 2 and Figure 4 The top of the rotating rod 10 extends above the hollow spherical shell 4 and is fixedly connected to a handle 20. Medical staff can easily rotate the rotating rod 10 left and right by gripping the handle 20.
[0026] For further details, please refer to Figure 2-4 The top of the drainage tube 1 is equipped with three sets of directional lines 13, which are aligned with the positions of the three sets of openings 5. The surface of the rotating rod 10 is connected to two sets of directional needles 14, which are aligned with the positions of the two sets of water guide holes 9. When the medical staff rotates the rotating rod 10, it will drive the two sets of directional needles 14 to rotate. The two sets of directional needles 14 indicate the positions of the two sets of water guide holes 9 on the ball core 8, so that the medical staff can accurately align the two sets of water guide holes 9 on the ball core 8 with the openings 5 located on the left and middle of the hollow ball shell 4, or the openings 5 located in the middle and right of the hollow ball shell 4, thus improving the convenience of operation.
[0027] For further details, please refer to Figure 1 Several sets of medical tape 15 are connected to the front end of the drainage tube 1 near the puncture needle 2. During the drainage process, the medical tape 15 can be attached to the patient's skin to fix the puncture needle 2 at the front end of the drainage tube 1, so as to prevent the puncture needle 2 from being disturbed and causing harm to the user's body.
[0028] For further details, please refer to Figure 6 The top of the collection tank 3 is provided with two sets of threaded ports 16. The rear ends of the first branch pipe 6 and the second branch pipe 7 are rotatably connected with threaded caps 17 that are threaded to the threaded ports 16. The user can connect the first branch pipe 6 and the second branch pipe 7 to the top of the collection tank 3 by unscrewing the threaded caps 17, so that the water in the first branch pipe 6 and the second branch pipe 7 can be collected into the collection tank 3. Alternatively, the first branch pipe 6 and the second branch pipe 7 can be removed from the top of the collection tank 3, and the drainage tube 1, the puncture needle 2, the first branch pipe 6, and the second branch pipe 7 can be replaced as a whole.
[0029] For further details, please refer to Figure 6 A transparent observation window 18 is provided on the outer wall of the collection tank 3. The surface of the transparent observation window 18 is distributed with scale lines 19, which allows medical staff to observe the volume of liquid inside the collection tank 3 during the drainage process.
[0030] The above are merely preferred embodiments of this utility model and are not intended to limit the scope of this utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, or improvements made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
