Description

Technical Field

[0001] The utility model belongs to the technical field of medical appliances, and particularly relates to a tumor drainage device. Background Art

[0002] Tumor treatment is a major challenge in the medical field, especially for solid tumors. Traditional treatments such as surgical resection, radiotherapy, and chemotherapy often fail to completely eliminate tumor cells and cause significant damage to the patient's body. In recent years, with the development of minimally invasive technology and precision medicine, tumor drainage devices have received widespread attention as an emerging treatment method. Tumor drainage devices mainly establish drainage channels at the tumor site to drain fluid, necrotic tissue, etc. from the tumor, reducing the pressure of the tumor on surrounding tissues, while facilitating subsequent drug treatment, immunotherapy, etc., and have significant clinical application value.

[0003] Currently, most tumor drainage devices on the market use a catheter inserted into the tumor, draining it through negative pressure or gravity. For example, utility model patent publication CN219251139U discloses a tumor drainage device that uses a needle, a U-shaped positioning member, a clip, and other structures to drain fluid or tissue from a patient's tumor into an external chamber for subsequent treatment and observation. However, the following drawbacks still exist when using such a device for drainage:

[0004] 1. After draining tumor tissue and tumor waste fluid into the chamber, the device fails to effectively cool the waste fluid, causing it to spoil easily. Furthermore, the chamber is not equipped with a corresponding cover mechanism, resulting in poor stability during use. When the chamber is in use and comes into contact with external objects, it is prone to shaking and tipping over, causing the fluid and necrotic tissue collected inside to shake, and even causing the fluid inside to leak out, contaminating the operating table and operating instruments, affecting the drainage surgery and the observation effect.

[0005] 2. The above device cannot effectively clear the drainage tube during drainage, and the presence of flocculent matter in the tumor tissue and tumor waste fluid during the drainage process can easily cause blockage of the drainage tube.

[0006] Therefore, the present invention designs a new tumor drainage device to solve the problems existing in the above-mentioned prior art. Utility Model Content

[0023] (3) Beneficial effects

[0024] Compared with the existing technology, the present invention provides a tumor drainage device with the following beneficial effects:

[0025] 1. The stabilizing assembly allows waste liquid to be directed to the waste liquid bin through a conduit.

[0026] 2. The setting of the limit assembly can prevent the waste liquid gas from scattering under the cooperation of the sealing strip and the partition. At the same time, the waste liquid gas is utilized through the air port and the connecting chamber to control the expansion of the bellows. On the basis of effectively ensuring the cooling effect of the waste liquid inside the waste liquid chamber, it can also reduce the use of coolant and prevent the direct discharge of waste gas from affecting the external environment.

[0027] 3. Through the setting of the anti-blocking component, during the drainage process, the connection between the connecting spring plate and the card plate can be released, so that the connecting sleeve can slide on the surface of the catheter, and the magnet can be moved above the built-in warehouse, so that the magnet and the magnetic ring attract each other, and then the magnetic ring will move inside the catheter to clear the blockage inside the catheter, ensuring the smoothness of drainage, and solving the problem of easy blockage of the drainage tube in the existing technology.

DETAILED DESCRIPTION

[0035] The following will be combined with the accompanying drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described 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.

[0036] Example 1:

[0037] like Figures 1-6 As shown, a tumor drainage device comprises:

[0038] A conduit 1, the lower end of which is fixedly connected to a valve body 2;

[0039] The drainage mechanism 3 is installed on the surface of the valve body 2 and extends to the lower end of the valve body 2; wherein, it includes a sealing cover 34 fixedly arranged on the surface of the valve body 2 and an anti-blocking component 35 movably arranged on the surface of the conduit 1, a storage box 33 is installed on the inner side of the sealing cover 34, and a stabilizing component 31 is arranged inside the storage box 33, and limiting components 32 are arranged on both sides of the stabilizing component 31, and the upper end of the limiting component 32 passes through the top of the sealing cover 34.

[0040] During use, the tumor tissue or waste liquid drained out is collected by using the storage box 33, and the waste liquid in the storage box 3 is auxiliary stabilized by using the stabilization component 31, so that the waste liquid will not be easily spilled in the event of an external collision; the limiting component 32 can improve the accuracy of the drainage process.

[0041] Example 2:

[0042] like Figure 1 、 Figure 3 、 Figure 3 and Figure 4 As shown, the stabilizing assembly 31 includes two partitions 311 fixedly connected to the inner bottom wall of the storage box 33. A sealing strip 312 is provided on the upper end of the partition 311. The sealing strip 312 is fixedly connected to the inner top wall of the sealing cover 34 and matches the adjacent partition 311. A waste liquid bin 313 is formed between the two partitions 311, and a cold liquid bin 314 is formed between the partition 311 and the inner wall of the adjacent storage box 33. An air guide 318 is fixedly connected between the two partitions 311.

[0043] A plurality of side holes 315 are formed on the side of the partition plate 311 below the air guide tube 318. A stabilizing tube 316 is fixedly connected to the inner wall of the side hole 315. The longitudinal cross section of the stabilizing tube 316 is elliptical.

[0044] The end of the stabilizing tube 316 is in communication with the interior of the adjacent cold liquid tank 314 , and a plurality of stabilizing rings 317 are fixedly connected to the surface of the stabilizing tube 316 ;

[0045] Both ends of the air guide pipe 318 penetrate into the interior of the adjacent cold liquid tank 314, and an air port 319 is opened on the surface of the air guide pipe 318;

[0046] During use, the waste liquid is directed to the waste liquid bin 313 through the conduit 1, and then the waste liquid inside the waste liquid bin 313 is cooled by the cold liquid bins 314 on both sides. In addition, with the cooperation of the sealing strip 312 and the partition 311, the waste liquid gas inside the waste liquid bin 313 can be prevented from scattering. The cooled waste liquid can reduce the generation of strong odors. In addition, the material of the partition 311 is a soft rubber component. When the waste liquid inside the waste liquid bin 313 is shaken by external collisions, the partition 311 can follow the pressure changes and deform, absorbing the energy during the shaking, thereby reducing the amplitude of the waste liquid following the shaking and reducing the occurrence of waste liquid splashing. The side holes 315 of different horizontal heights are staggered, and the stabilizing tube 316 can increase the contact area with the waste liquid, improving the cooling effect. In the case of the waste liquid being shaken by collisions, the stabilizing tube 316 can also help the internal waste liquid quickly maintain a relatively stable state, reducing the occurrence of waste liquid splashing. The provision of multiple stabilizing rings 317 also increases the contact area, improves the cooling effect of the stabilizing tube 316 on the waste liquid, and when the internal waste liquid shakes, the stabilizing ring 317 can assist in improving the stabilizing tube 316 to alleviate the liquid shaking. The opening of the air port 319 can allow the gas located at the upper part of the waste liquid tank 313 to be discharged outward.

[0047] Example 3:

[0048] like Figure 2 、 Figure 3 、 Figure 4 and Figure 5 The cam 328 is a hollow tube 329 that is provided with a screw thread on the top of the cam 329, and the hollow tube 329 has a hollow tube 329, and the hollow tube 329 has a hollow tube 329. When the cam 329 is in the open position, the cam 329 is in the open position, and the hollow tube 329 is in the open position.

[0049] In this embodiment, when in use, the gas discharged from the air port 319 will push the top seat 324 upward in the connecting chamber 322, causing the bellows 325 to expand, and then the liquid level inside the cold liquid chamber 314 will rise, so that the liquid will pass through the stabilizing tube 316 to form a cooling effect on the waste liquid inside the waste liquid chamber 313, thereby reducing the use of cooling liquid and utilizing the waste gas at the same time, avoiding the direct discharge of the waste gas to affect the external environment.

[0050] At the same time, when the top seat 324 is used to move upward, the round rod 326 can slide up and down on the inner wall of the guide tube 329 through the screw connection between the lower end of the round rod 326 and the top seat 324, thereby guiding the expansion and movement direction of the bellows 325.

[0051] By cooperating with the plurality of limiting grooves 327 , the round rod 326 is limited, so that the expansion speeds of the bellows 325 are the same, and the uniformity of the cooling liquid level is maintained.

[0052] Example 4:

[0053] like Figure 1 、 Figure 6 As shown, the anti-blocking assembly 35 includes a connecting sleeve 351 that is sleeved on the surface of the catheter 1. Both ends of the connecting sleeve 351 are fixedly connected to connecting spring plates 352. The opposite sides of the two connecting spring plates 352 are fixedly connected to clamping blocks 353. The other end of the lower connecting spring plate 352 is fixedly connected to a clamping plate 355. The upper end of the lower connecting spring plate 352 is fixedly connected to a magnet 354. The anti-blocking assembly 35 also includes an internal compartment 356 embedded in the surface of the catheter 1. The internal compartment 356 is provided with a magnetic ring 357.

[0054] During use, the clamping plate 355 is fixedly connected to a plurality of latch teeth near the side of the connecting sleeve 351, and the adjacent latch teeth are engaged with the end of the upper end connecting spring plate 352. When the two clamping blocks 353 clamp the catheter 1, causing the catheter 1 to deform, the accumulated fluid inside the catheter 1 accumulates and blocks at the deformed position. At this time, by releasing the engagement between the connecting spring plate 352 and the clamping plate 355, the connecting sleeve 351 can slide on the surface of the catheter 1, and the magnet 354 is moved above the built-in bin 356, so that the magnet 354 and the magnetic ring 357 attract each other, and then the magnetic ring 357 will move inside the catheter 1, and the blockage inside the catheter 1 will be cleared to ensure smooth drainage.

[0055] When the tumor drainage device of the utility model is used:

[0056] The waste liquid is guided to the waste liquid bin 313, and then the waste liquid inside the waste liquid bin 313 is cooled by the cold liquid bins 314 on both sides. With the cooperation of the sealing strip 312 and the partition 311, the waste liquid gas can be prevented from being scattered. The cooled waste liquid can reduce the generation of strong odor. The partition 311 can be made of a soft rubber material. When the waste liquid inside the waste liquid bin 313 is shaken by external collision, the partition 311 can be deformed in response to the pressure change. The side holes 315 at different heights are staggered. When the waste liquid is shaken by collision, the stabilizing tube 316 helps the internal waste liquid to quickly maintain a relatively stable state. The stabilizing ring 317 helps to raise the stabilizing tube 316 to alleviate the shaking of the liquid.

[0057] When the catheter 1 is blocked, the connection between the connecting spring plate 352 and the clamping plate 355 is released, so that the connecting sleeve 351 can slide on the surface of the catheter 1, and the magnet 354 is moved above the built-in bin 356, so that the magnet 354 and the magnetic ring 357 attract each other, and then the magnetic ring 357 will move inside the catheter 1, and the blockage inside the catheter 1 will be cleared, thereby ensuring the smooth drainage of the catheter 1.
