Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of tumor effusion, and in particular to a rapid drainage device for tumor effusion. Background Art
[0002] Cancer patients often have pleural or abdominal effusion. In the early stages of effusion, severe chest pain will occur on the affected side, like a needle or knife prick, and will be more severe with deep breathing or coughing. This is due to the friction between the viscous fluid and the two layers of pleura. As the effusion increases, the patient will experience shortness of breath, palpitations and difficulty breathing, and the condition will gradually worsen. In order to relieve the pain of cancer patients, the effusion needs to be drained.
[0003] Chinese patent application publication number CN110732048B discloses a drainage device for oncology, comprising a puncture needle having a cavity therein, and further comprising: a drainage tube disposed in the cavity within the puncture needle; an end cap mounted at the end of the puncture needle, the end cap having a tapered surface, one end of the drainage tube extending through the end cap, the end cap also having a plurality of perfusion holes; a hollow tube connected to the top of the puncture needle via a connecting assembly; and a fixing assembly disposed on the connecting assembly, the fixing assembly being used to fix the puncture needle to the patient's body after puncture.
[0004] Although this arrangement is reasonably designed and ingenious, it can quickly absorb accumulated mucus during drainage, and after the puncture needle is inserted, the puncture needle can be stably fixed and will not shake, making the drainage more stable. However, the collection bottle of this arrangement is not easy to remove during the drainage process of the device. This will result in that when there is still some space left in the collection bottle, too much accumulated fluid will be drained through the drainage device, resulting in the accumulation of fluid being unable to be completely contained, and the drainage operation needs to be stopped.
[0005] At the same time, a negative pressure suction component is required to suck out the effusion of the fluid collection component. This process may cause discontinuous drainage of the effusion, and the effusion may flow back into the patient's body, causing discomfort to the patient undergoing drainage. Summary of the Invention
[0006] The purpose of the present invention is to provide a rapid drainage device for tumor fluid accumulation to solve the problems raised in the above background technology.
[0007] To solve the above technical problems, the present invention is achieved through the following technical solutions:
[0008] The present invention is a rapid drainage device for tumor effusion, comprising a base frame, a fixing rod connected to the outer wall of the base frame, a tube body installed on the top of the base frame, and a driving assembly installed on the outer wall of the fixing rod;
[0009] The tube body is provided with two ports, the drive assembly extends into the interior of the tube body through one of the ports of the tube body, and the other port of the tube body is provided with a thread;
[0010] A second collecting box is plugged into the bottom outer wall of the tube body. The second collecting box is arranged obliquely on the bottom outer wall of the tube body. A discharge port is provided at the bottom of the second collecting box, which is in a closed state when discharge is not required.
[0011] A sealing assembly is installed inside the second collection box, which is used to seal the top port of the second collection box after the internal liquid of the second collection box is filled;
[0012] A conical shell is installed on the inner side of the port of the tube body, and a first collecting component for collecting accumulated fluid is installed on the outer wall of one end of the tube body close to the conical shell;
[0013] When the driving component retracts, the first collecting component remains closed and the accumulated liquid is guided to the interior of the second collecting box. When the second collecting box is full and closed, the driving component advances to drive the first collecting component to open, and the accumulated liquid is guided to the first collecting component for further collection.
[0014] The purpose of the above arrangement is that one port of the tube body has a thread that can be connected to an external device, which may be a tube connected to the patient's body to drain the accumulated fluid. When the drainage of tumor fluid begins, the accumulated fluid enters the tube body through the threaded port.
[0015] The driving assembly works and extends into the interior of the tube body through a port of the tube body. During the retraction of the driving assembly, the first collecting assembly remains closed, and the second collecting box plugged into the outer wall of the bottom of the tube body is tilted, which is conducive to the accumulated liquid flowing into the second collecting box under the action of gravity. When the second collecting box is full of liquid, the sealing assembly installed inside it will seal the top port of the second collecting box. At this time, the driving assembly advances. Since the second collecting box is already closed, the accumulated liquid can no longer enter the second collecting box, and the advancement of the driving assembly drives the first collecting assembly to open;
[0016] After the first collecting component is opened, the accumulated liquid is guided into the first collecting component for further collection. During this process, the accumulated liquid inside the tube body is already less. The conical shell installed on the inner side of the tube body port prevents the accumulated liquid from flowing back into the pipeline, so that the accumulated liquid can be reasonably transferred and collected between the first collecting component and the second collecting box to maintain the continuity of collection.
[0017] Furthermore, the driving assembly includes a first disc and a second disc, and a plurality of nylon sheets are provided on the outer walls of the first disc and the second disc, which are arranged opposite to each other to increase friction when the two discs rotate relative to each other;
[0018] The second disc is fixedly connected to the top of the fixing rod. A connecting shaft is provided on the top of the fixing rod. The connecting shaft passes through the second disc. The first disc is rotatably connected to the outer wall of the connecting shaft.
[0019] The purpose of the above arrangement is that the outer walls of the first and second discs in the drive assembly are provided with nylon material and are arranged opposite to each other. When the first and second discs are in operation and rotate relative to each other, the friction between the nylon materials provides a certain resistance to the movement between the first and second discs, thereby preventing the first disc from rotating too quickly and preventing the effusion from being extracted too quickly, causing discomfort to the patient.
[0020] The second disc is fixed on the top of the fixed rod. The connecting shaft on the top of the fixed rod passes through the second disc. The first disc is rotatably connected to the outer wall of the connecting shaft. This structure provides support for the rotation of the first disc relative to the second disc.
[0021] Furthermore, a transmission rod is rotatably connected to the outer wall of the first disc, an end of the transmission rod away from the first disc is rotatably connected to a connecting rod, an end of the connecting rod away from the transmission rod is connected to a piston, and the piston is slidably connected along the inner wall of the tube body.
[0022] The purpose of the above arrangement is that when the first disc rotates, the transmission rod connected to its outer wall will make circular motion as the first disc rotates. The connecting rod is connected to the piston, so when the transmission rod moves, it will drive the piston to slide along the inner wall of the tube body.
[0023] Furthermore, the wide opening of the conical shell faces the end of the tube body, and the narrow opening of the conical shell faces one side of the piston.
[0024] The purpose of the above arrangement is that after the accumulated liquid enters the tube body, the conical shell can guide the flow direction of the accumulated liquid, and the narrow opening is set to prevent the accumulated liquid from flowing back.
[0025] Furthermore, the closing assembly includes a ring body, a connecting rod and a valve plate. Two shallow grooves are provided on the top inner wall of the second collection box. The ring body is slidably connected between the two shallow grooves. The two valve plates are respectively rotatably connected to the top inner wall of the second collection box. The two valve plates form a circular plate to close the port of the second collection box. The two ends of the connecting rod are respectively rotatably connected to the valve plate and the ring body. The ring body is made of lightweight and corrosion-resistant material.
[0026] The purpose of the above setting is that when drainage begins, the threaded port of the tube body is connected to the patient by connecting an external pipe, and a negative pressure is formed inside the channel. During the retraction of the piston, the accumulated fluid enters the interior of the tube body through the channel, and the piston passes through the top port of the second collection box, and then the accumulated fluid flows into the interior of the second collection box. When the accumulated fluid in the second collection box is full, during this process, as the liquid level of the accumulated fluid inside the second collection box rises, the ring body slides between the shallow grooves. The ring body is made of lightweight and corrosion-resistant materials, such as certain plastics or lightweight metal alloys, which are more conducive to floating in the accumulated fluid. The rising liquid level props up the ring body and drives the valve plate to rotate through the connecting rod. The two valve plates form a circular plate to close the port of the second collection box.
[0027] Furthermore, when the two valve plates close the top port of the second collecting box, an acute angle is formed between the upper surface of the connecting rod and the lower surface of the valve plate.
[0028] The purpose of the above arrangement is that when the two valve plates close the ports, the upper surface of the connecting rod and the lower surface of the valve plates form an acute angle. This structure helps to maintain the stability of the closed state.
[0029] Furthermore, two notches are provided on the outer wall of one end of the tube body close to the first disc to facilitate the deflection of the transmission rod. The connecting rod is provided with an extension rod, which extends toward the first collecting component through the top notch of the tube body.
[0030] The purpose of the above arrangement is that the extension rod cooperates with the first collecting assembly.
[0031] Furthermore, the first collecting assembly includes a first collecting box, the first collecting box is connected to the tube body, and a baffle is slidably connected between the first collecting box and the tube body.
[0032] The purpose of the above setting is that when the second collection box is closed, the piston is pushed forward. Since the second collection box can no longer receive the accumulated liquid, the movement of the driving assembly is transmitted through the connecting rod. The connecting rod is provided with an extension rod, which extends toward the first collection assembly through the notch at the top of the tube body. The extension rod contacts the connecting frame, and the connecting frame is connected to the baffle. When the connecting rod pushes the connecting frame, the baffle slides between the first collection box and the tube body, allowing the accumulated liquid to flow into the interior of the first collection box.
[0033] Furthermore, a connecting frame is connected to the outer wall of the baffle, and the top of the connecting frame is in contact with the extended end of the connecting rod.
[0034] The purpose of the above arrangement is that the extended end of the connecting rod is used to push the top of the connecting frame.
[0035] Furthermore, a cylindrical shell is connected to the outer wall of the first collection box, a piston rod is connected to the outer wall of the baffle, the piston rod extends to the inside of the cylindrical shell for sliding connection, and a spring for resetting the baffle is installed inside the cylindrical shell.
[0036] The purpose of the above setting is that the piston rod on the outer wall of the baffle extends to the inside of the cylindrical shell for sliding connection, and the spring inside the cylindrical shell provides a reset force for the baffle. When the drive assembly moves in the opposite direction, the baffle can be reset under the action of the spring, thereby achieving the closure of the first collection box or controlling the inflow and outflow of accumulated liquid.
[0037] The present invention has the following beneficial effects:
[0038] (1) The present invention drives the assembly forward through the arrangement of the first collecting assembly and the conical shell. Since the second collecting box is closed, the accumulated fluid can no longer enter the second collecting box, and the advancement of the driving assembly drives the first collecting assembly to open. After the first collecting assembly is opened, the accumulated fluid is guided to the first collecting assembly for further collection. During this process, the accumulated fluid inside the tube body is already less. The conical shell installed on the inner side of the tube body port prevents the accumulated fluid from flowing back into the pipe, so that the accumulated fluid is reasonably transferred and collected between the first collecting assembly and the second collecting box to maintain the continuity of the collection, while reducing the setting of the conical shell when the driving assembly is advanced again to prevent the accumulated fluid from flowing back into the pipe and causing discomfort to the patient.
[0039] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS

[0052] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0053] The present invention is a rapid drainage device for tumor effusion, such as Figure 1 - Figure 9 As shown, it includes a base frame 1, a fixing rod 101 is connected to the outer wall of the base frame 1, a tube body 2 is installed on the top of the base frame 1, and a driving assembly 5 is installed on the outer wall of the fixing rod 101;
[0054] The pipe body 2 is provided with two ports, and the drive assembly 5 extends into the interior of the pipe body 2 through one of the ports of the pipe body 2, and the other port of the pipe body 2 is provided with a thread;
[0055] A second collecting box 4 is inserted into the outer wall of the bottom of the tube body 2. The second collecting box 4 is arranged obliquely on the outer wall of the bottom of the tube body 2. A discharge port is provided at the bottom of the second collecting box 4, which is in a closed state when discharge is not required.
[0056] A sealing assembly is installed inside the second collection box 4, which is used to seal the top port of the second collection box 4 after the internal liquid of the second collection box 4 is filled;
[0057] A conical shell 201 is installed on the inner side of the port of the tube body 2, and a first collecting component 3 for collecting the accumulated fluid is installed on the outer wall of one end of the tube body 2 close to the conical shell 201;
[0058] When the driving component 5 retracts, the first collecting component 3 remains closed and the accumulated liquid is guided to the inside of the second collecting box 4. When the second collecting box 4 is full and closed, the driving component 5 advances to drive the first collecting component 3 to open, and the accumulated liquid is guided to the first collecting component 3 for further collection.
[0059] In this embodiment, the purpose of the above arrangement is that one port of the tube body 2 has a thread that can be connected to an external device, which may be a tube connected to the patient's body to drain the accumulated fluid. When the tumor fluid begins to be drained, the accumulated fluid enters the tube body 2 through the threaded port.
[0060] The driving assembly 5 works and extends into the interior of the tube body 2 through a port of the tube body 2. During the retraction of the driving assembly 5, the first collecting assembly 3 remains closed, and the second collecting box 4 plugged into the outer wall of the bottom of the tube body 2 is arranged at an angle, which is conducive to the accumulated liquid flowing into the second collecting box 4 under the action of gravity. When the second collecting box 4 is full of liquid, the sealing assembly installed inside it will seal the top port of the second collecting box 4. At this time, the driving assembly 5 advances. Since the second collecting box 4 is already closed, the accumulated liquid can no longer enter the second collecting box 4, and the advancement of the driving assembly 5 drives the first collecting assembly 3 to open;
[0061] After the first collecting component 3 is opened, the accumulated liquid is guided to the first collecting component 3 for further collection. During this process, the accumulated liquid inside the tube body 2 is already less. The conical shell 201 installed on the inner side of the port of the tube body 2 prevents the accumulated liquid from flowing back into the pipeline, so that the accumulated liquid is reasonably transferred and collected between the first collecting component 3 and the second collecting box 4 to maintain the continuity of collection.
[0062] As an implementation method, Figure 5 As shown, further:
[0063] The driving assembly 5 includes a first disc 501 and a second disc 502. The outer walls of the first disc 501 and the second disc 502 are both provided with a plurality of nylon sheets arranged opposite to each other to increase friction when the two discs rotate relative to each other.
[0064] The second disc 502 is fixedly connected to the top of the fixing rod 101. A connecting shaft is provided on the top of the fixing rod 101. The connecting shaft passes through the second disc 502. The first disc 501 is rotatably connected to the outer wall of the connecting shaft.
[0065] In this embodiment, the purpose of the above arrangement is that the outer walls of the first disk 501 and the second disk 502 in the drive assembly 5 are provided with nylon material and are arranged opposite to each other. When the first disk 501 and the second disk 502 are in operation and rotate relative to each other, the friction between the nylon materials provides a certain resistance to the movement between the first disk 501 and the second disk 502, thereby preventing the first disk 501 from rotating too quickly and preventing the effusion from being extracted too quickly and causing discomfort to the patient.
[0066] The second disc 502 is fixed to the top of the fixed rod 101. The connecting shaft at the top of the fixed rod 101 passes through the second disc 502. The first disc 501 is rotatably connected to the outer wall of the connecting shaft. This structure provides support for the rotation of the first disc 501 relative to the second disc 502.
[0067] As an implementation method, Figure 5 As shown, further:
[0068] A transmission rod 503 is rotatably connected to the outer wall of the first disc 501 , and a connecting rod 504 is rotatably connected to the end of the transmission rod 503 away from the first disc 501 . A piston 505 is connected to the end of the connecting rod 504 away from the transmission rod 503 . The piston 505 is slidably connected along the inner wall of the tube body 2 .
[0069] In this embodiment, the purpose of the above arrangement is that when the first disc 501 rotates, the transmission rod 503 connected to its outer wall will perform circular motion along with the rotation of the first disc 501. The connecting rod 504 is connected to the piston 505, so when the transmission rod 503 moves, it will drive the piston 505 to slide along the inner wall of the tube body 2.
[0070] As an implementation method, Figure 5 As shown, further:
[0071] The wide end of the conical shell 201 faces the end of the tube body 2 , and the narrow end of the conical shell 201 faces one side of the piston 505 .
[0072] In this embodiment, the purpose of the above arrangement is that after the accumulated liquid enters the tube body 2, the conical shell 201 can guide the flow direction of the accumulated liquid, and the narrow opening is set to prevent the accumulated liquid from flowing back.
[0073] As an implementation method, Figure 8 - Figure 9 As shown, further:
[0074] The closing assembly includes a ring body 601, a connecting rod 602 and a valve plate 603. Two shallow grooves 401 are provided on the top inner wall of the second collection box 4. The ring body 601 is slidably connected between the two shallow grooves 401. The two valve plates 603 are respectively rotatably connected to the top inner wall of the second collection box 4. The two valve plates 603 form a circular plate to close the port of the second collection box 4. The two ends of the connecting rod 602 are respectively rotatably connected to the valve plate 603 and the ring body 601. The ring body 601 is made of lightweight and corrosion-resistant material.
[0075] In this embodiment, the purpose of the above-mentioned setting is that when drainage begins, the threaded port of the tube body 2 is connected to the patient by connecting an external pipe, and a negative pressure is formed inside the channel. During the retraction of the piston 505, the accumulated fluid enters the interior of the tube body 2 through the channel, and the piston 505 passes through the top port of the second collection box 4, and then the accumulated fluid flows into the interior of the second collection box 4. When the accumulated fluid in the second collection box 4 is full, during this process, as the liquid level of the accumulated fluid in the second collection box 4 rises, the ring body 601 slides between the shallow grooves. The ring body 601 is made of lightweight and corrosion-resistant materials, such as certain plastics or lightweight metal alloys, which are more conducive to floating in the accumulated fluid. The rising liquid level props up the ring body 601 and drives the valve plate 603 to rotate through the connecting rod 602. The two valve plates 603 form a circular plate to close the port of the second collection box 4.
[0076] As an implementation method, Figure 9 As shown, further:
[0077] When the two valve plates 603 close the top port of the second collecting box 4 , the upper surface of the connecting rod 602 and the lower surface of the valve plate 603 form an acute angle.
[0078] In this embodiment, the purpose of the above arrangement is that when the two valve plates 603 close the ports, the upper surface of the connecting rod 602 and the lower surface of the valve plate 603 form an acute angle, and this structure helps to maintain the stability of the closed state.
[0079] As an implementation method, Figure 5 As shown, further:
[0080] Two notches are provided on the outer wall of one end of the tube body 2 close to the first disc 501 to facilitate the deflection of the transmission rod 503. The connecting rod 504 is provided with an extension rod, which extends toward the first collecting component 3 through the top notch of the tube body 2.
[0081] In this embodiment, the purpose of the above arrangement is to enable the extension rod to cooperate with the first collecting assembly 3 .
[0082] As an implementation method, Figure 2 As shown, further:
[0083] The first collecting assembly 3 includes a first collecting box 301 . The first collecting box 301 is in communication with the tube body 2 . A baffle 302 is slidably connected between the first collecting box 301 and the tube body 2 .
[0084] In this embodiment, the purpose of the above-mentioned setting is that when the second collecting box 4 is closed, the piston 505 is pushed forward. Since the second collecting box 4 can no longer receive the accumulated liquid, the movement of the driving assembly 5 is transmitted through the connecting rod 504. The connecting rod 504 is provided with an extension rod, which extends toward the first collecting assembly 3 through the notch at the top of the tube body 2. The extension rod contacts the connecting frame 304, and the connecting frame 304 is connected to the baffle 302. When the connecting rod 504 pushes the connecting frame 304, the baffle 302 slides between the first collecting box 301 and the tube body 2, so that the accumulated liquid can flow into the interior of the first collecting box 301.
[0085] As an implementation method, Figure 2 and Figure 5 As shown, further:
[0086] A connecting frame 304 is connected to the outer wall of the baffle 302 , and the top of the connecting frame 304 contacts the extended end of the connecting rod 504 .
[0087] In this embodiment, the purpose of the above arrangement is that the extended end of the connecting rod 504 is used to push the top of the connecting frame 304 .
[0088] As an implementation method, Figure 2 - Figure 4 As shown, further:
[0089] A cylindrical shell 303 is connected to the outer wall of the first collection box 301, and a piston rod is connected to the outer wall of the baffle 302. The piston rod extends into the interior of the cylindrical shell 303 for sliding connection. A spring 305 for resetting the baffle 302 is installed inside the cylindrical shell 303.
[0090] In this embodiment, the purpose of the above-mentioned setting is that the piston rod on the outer wall of the baffle 302 extends to the inside of the cylindrical shell 303 for sliding connection, and the spring 305 in the cylindrical shell 303 provides a reset force for the baffle 302. When the driving assembly 5 moves in the opposite direction, the baffle 302 can be reset under the action of the spring 305, thereby achieving the closure of the first collection box 301 or controlling the inflow and outflow of the accumulated liquid.
[0091] During use, the outer walls of the first disc 501 and the second disc 502 in the driving assembly 5 are provided with nylon material and are arranged opposite to each other. When the first disc 501 and the second disc 502 are working and rotate relative to each other, the friction between the nylon materials provides a certain resistance to the movement between the first disc 501 and the second disc 501, thereby preventing the first disc 501 from rotating too fast and preventing the effusion from being extracted too quickly and causing discomfort to the patient.
[0092] The second disc 502 is fixed to the top of the fixed rod 101. The connecting shaft at the top of the fixed rod 101 passes through the second disc 502. The first disc 501 is rotatably connected to the outer wall of the connecting shaft. This structure provides support for the rotation of the first disc 501 relative to the second disc 502.
[0093] When the first disc 501 rotates, the transmission rod 503 connected to its outer wall will make a circular motion along with the rotation of the first disc 501. The connecting rod 504 is connected to the piston 505. Therefore, when the transmission rod 503 moves, it will drive the piston 505 to slide along the inner wall of the tube 2.
[0094] After the accumulated liquid enters the tube body 2, the conical shell 201 can guide the flow direction of the accumulated liquid, and the narrow opening prevents the accumulated liquid from flowing back.
[0095] When drainage begins, the threaded port of the tube body 2 is connected to the patient through an external tube, creating a negative pressure inside the channel. As the piston 505 retracts, the accumulated fluid enters the tube body 2 through the channel. The piston 505 passes through the top port of the second collection box 4, and the accumulated fluid then flows into the second collection box 4.
[0096] When the accumulated liquid in the second collection box 4 is filled, during this process, as the liquid level of the accumulated liquid inside the second collection box 4 rises, the ring body 601 slides between the shallow grooves 401. The shallow grooves 401 are located on the inner wall of the second collection box 4 and are vertically distributed. The ring body 601 is made of a lightweight and corrosion-resistant material, such as certain plastics or lightweight metal alloys, which is more conducive to floating in the accumulated liquid. The rising liquid level props up the ring body 601 and lifts it up. The connecting rod 602 drives the valve plate 603 to rotate. The two valve plates 603 form a circular plate to close the port of the second collection box 4. When the two valve plates 603 close the port, the upper surface of the connecting rod 602 and the lower surface of the valve plate 603 form an acute angle. This structure helps to maintain the stability of the closed state.
[0097] When the second collection box 4 is closed, the piston 505 advances. Since the second collection box 4 can no longer receive the accumulated liquid, the movement of the drive assembly 5 is transmitted through the connecting rod 504. The connecting rod 504 is provided with an extension rod, which extends through the notch at the top of the tube body 2 toward the first collection assembly 3. The extension rod contacts the connecting frame 304, which is connected to the baffle 302. When the connecting rod 504 pushes the connecting frame 304, the baffle 302 slides between the first collection box 301 and the tube body 2, allowing the accumulated liquid to flow into the interior of the first collection box 301.
[0098] The piston rod on the outer wall of the baffle 302 extends to the inside of the cylindrical shell 303 for sliding connection. The spring 305 in the cylindrical shell 303 provides a reset force for the baffle 302. After compression, the cylindrical shell 303 moves toward one side of the baffle 302, which compresses the spring 305. When there is no force, the cylindrical shell 303 is pushed to reset by the spring 305. When the drive assembly 5 moves in the opposite direction, the baffle 302 can be reset under the action of the spring 305, thereby achieving the closure of the first collection box 301 or controlling the inflow and outflow of accumulated liquid.
