Description

Technical Field

[0001] This utility model relates to the field of drainage tube technology, specifically to a disposable, detachable, dual-purpose abdominal irrigation drainage tube. Background Technology

[0002] Abdominal surgery involves risks such as intraoperative effusion and anastomotic leakage. Anastomotic leakage, in particular, can easily lead to fluid accumulation, infection, necrosis, and vascular erosion, causing massive bleeding. This often necessitates a second surgery, which is highly detrimental to the patient and imposes significant financial burden. The primary solution to these problems is to maintain unobstructed drainage of the abdominal cavity using an abdominal drainage tube. Because the accumulated fluid often contains solid matter, it can easily become blocked during drainage. Therefore, a negative pressure device is typically connected to the drainage port of the tube. However, if the pressure of the negative pressure device is not properly controlled, or if the blockage is severe, the drainage tube can remain in a vacuum state for an extended period. If the tube is cleared under these conditions, the resulting pressure difference can damage abdominal tissues and cause further blockage, hindering patient recovery. Furthermore, since the main drainage tube is placed during surgery, replacing it if it becomes unusable due to blockage is also difficult.

[0003] In existing technologies, methods such as installing an irrigation tube outside the drainage tube are used to address the aforementioned problems. However, in practical use, it has been found that the irrigation fluid in the irrigation tube is directed into the abdominal cavity to dilute the peritoneal fluid. However, it cannot clear blockages within the drainage tube. Therefore, there is an urgent need to design a safe, effective, and easy-to-operate abdominal irrigation and drainage tube. Utility Model Content

[0004] The purpose of this utility model is to at least partially solve one of the technical problems in related technologies. In view of this, a disposable, detachable, dual-purpose abdominal irrigation and drainage tube is provided, including a main drainage tube and an irrigation tube. The irrigation tube is attached to the outer wall of the main drainage tube and extends in the same direction as the main drainage tube. The front end of the main drainage tube and the side wall near the front end of the main drainage tube are provided with several external drainage holes. The front end of the irrigation tube is closed and a flushing hole is provided on the side wall near the front end of the irrigation tube. The flushing hole is directly opposite one of the external drainage holes on the side wall of the front end of the main drainage tube. An internal drainage tube is detachably inserted into the rear side wall of the main drainage tube. The front end of the internal drainage tube and the side wall near the front end of the internal drainage tube are provided with several internal drainage holes. The internal drainage tube extends along the internal channel of the main drainage tube to the side of the external drainage hole. The hardness of the internal drainage tube is greater than that of the main drainage tube.

[0005] According to an example of the present invention, a sleeve hole is provided on the side wall near the rear end of the main drainage tube, and a sealing plug is installed at the sleeve hole. The inner drainage tube is movably inserted into the inner channel of the main drainage tube through the sealing plug, and a connecting plug for connecting an external drainage device is sleeved at the end of the inner drainage tube that extends out of the main drainage tube.

[0006] According to one example of the present invention, the rear end of the main drainage tube is equipped with a first tail connector for connecting an external drainage device, and the first tail connector is provided with a first sealing plug that can close the first tail connector.

[0007] According to one example of the present invention, the rear end of the flushing pipe is equipped with a second tail connector for connecting to an external flushing device, and the second tail connector is provided with a second sealing plug that can close the second tail connector.

[0008] According to one example of this utility model, the internal drainage tube is a bamboo joint tube, and a plurality of annular rigid joints are arranged at equal intervals on the bamboo joint tube. The hardness of the bamboo joint tube at the annular rigid joints is greater than the hardness of the tube segment between two adjacent annular rigid joints.

[0009] According to one example of the present invention, a scraper structure is also provided on the outer wall of the front end of the inner drainage tube. The scraper structure is used to assist in pushing the sealing material at the outer drainage hole when the inner drainage tube is pumped out by external force.

[0010] According to an example of the present invention, the scraper structure includes a plurality of scraper rings that are equally spaced on the outer wall of the front end of the inner drainage tube. The scraper rings are coaxially arranged with the inner drainage tube and have a trumpet-shaped structure, with the trumpet openings of two adjacent scraper rings facing opposite directions.

[0011] According to an example of the present invention, the scraper structure includes a plurality of triangular scraper strips disposed on the outer wall of the front end of the inner drainage tube, and the plurality of triangular scraper strips are equally spaced along the circumferential direction of the outer wall of the front end of the inner drainage tube.

[0012] According to one example of the present invention, the diameter of the external drainage hole is smaller than the diameter of the internal drainage tube.

[0013] According to one example of this utility model, a clip is provided on the outer wall of the front end of the main drainage tube, and the front end of the flushing tube is detachably fixed at the clip; or, the outer wall of the front end of the main drainage tube and the outer wall of the front end of the flushing tube are weakly connected by an ultra-thin medical PVC strip.

[0014] Compared with the prior art, the technical solution of this utility model has the following advantages:

[0015] 1. By integrating the main drainage tube and the flushing tube into one parallel unit, and setting the flushing hole of the flushing tube to face the external drainage hole layout, compared with the conventional direct flushing of the abdominal cavity, the flushing fluid directly hits the inner wall of the main drainage tube. When flushing in the narrow tube space, the flushing water pressure can be increased to enhance the flushing effect and effectively disperse the blockage.

[0016] 2. A high-hardness inner drainage tube is nested inside the main drainage tube. When the outer drainage hole at the front end of the main drainage tube is severely blocked, the inner drainage tube can be pulled back and forth to frequently scrape the blockage in the main drainage tube, which has a certain mechanical breaking effect and can speed up the unblocking process.

[0017] 3. The irrigation tube is detachable from the main drainage tube, which can be removed after surgery as needed, turning the entire tube into a simpler ordinary abdominal drainage tube, which is beneficial to the patient's recovery.

[0018] Additional aspects and advantages of this invention will be set forth in part in the description which follows, and in part will be obvious from the description, or may be learned by practice of the invention. Attached Figure Description

[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model. Example

[0027] Please see Figure 1 , Figure 2 As shown, this utility model provides a disposable, detachable, dual-purpose abdominal irrigation and drainage tube, including a main drainage tube 1 and an irrigation tube 2. The irrigation tube 2 is attached to the outer wall of the main drainage tube 1 and extends in the same direction as the main drainage tube 1. The front end of the main drainage tube 1 and the side wall near the front end of the main drainage tube 1 are provided with several external drainage holes 3. The front end of the irrigation tube 2 is closed and a flushing hole 4 is provided on the side wall near the front end of the irrigation tube 2. The flushing hole 4 is directly opposite one of the external drainage holes 3 on the side wall of the front end of the main drainage tube. An internal drainage tube 5 is detachably and movablely inserted into the rear side wall of the main drainage tube 1. The front end of the internal drainage tube 5 and the side wall near the front end of the internal drainage tube 5 are provided with several internal drainage holes 6. The internal drainage tube 5 extends along the inner channel of the main drainage tube 1 to the side of the external drainage hole 3. The hardness of the internal drainage tube 5 is greater than that of the main drainage tube 1.

[0028] In this embodiment, the main drainage tube 1 and the flushing tube 2 are integrated and run in parallel. The flushing hole 4 of the flushing tube 2 is arranged facing the external drainage hole 3. Compared with conventional direct abdominal flushing, the flushing fluid directly hits the inner wall of the main drainage tube. When flushing in a narrow tube space, the flushing water pressure can be increased to enhance the flushing effect and effectively disperse the blockage.

[0029] In this embodiment, a high-hardness inner drainage tube 5 is nested inside the main drainage tube 1. When the outer drainage hole 3 at the front end of the main drainage tube 1 is severely blocked, the inner drainage tube 5 can be pulled back and forth to frequently scrape the blockage in the main drainage tube 1, which has a certain mechanical breaking effect and can speed up the unblocking.

[0030] As one type of installation of the internal drainage tube 5, a sleeve hole 7 is provided on the side wall of the main drainage tube 1 near the rear end of the main drainage tube 1. A sealing plug is installed at the sleeve hole 7. The internal drainage tube 5 is movably inserted into the inner channel of the main drainage tube 1 through the sealing plug. The end of the internal drainage tube 5 that protrudes from the main drainage tube 1 is fitted with a connecting plug 8 for connecting to an external drainage device. The internal drainage tube 5 can be pulled back and forth relative to the sealing plug under the action of external force, but the plug still maintains a sealing effect and will not leak.

[0031] According to one example of this utility model, the rear end of the main drainage tube 1 is equipped with a first tail connector 9 for connecting to an external drainage device, and the first tail connector 9 is provided with a first sealing plug 10 for closing the first tail connector 9. The rear end of the flushing tube 2 is equipped with a second tail connector 11 for connecting to an external flushing device, and the second tail connector 11 is provided with a second sealing plug 12 for closing the second tail connector 11. The tail connector is used to connect to an external drainage device or flushing device, and the sealing plug is used to seal the corresponding drainage channel or flushing channel opening under normal conditions.

[0032] As one design example, such as Figure 3 As shown, preferably, the inner drainage tube 5 is a bamboo joint tube, with several annular rigid joints 13 evenly spaced on the bamboo joint tube. The hardness of the bamboo joint tube at the annular rigid joints 13 is greater than the hardness of the tube section between two adjacent annular rigid joints 13. This design makes the inner drainage tube 5 have higher hardness at multiple nodes, but it also has the ability to bend and deform as a whole. The combination of softness and hardness can meet the requirements of bending and conveying with the main drainage tube, and can also scrape the inner wall of the front end of the main drainage tube.

[0033] According to one example of the present invention, a scraper structure is also provided on the outer wall of the front end of the inner drainage tube 5. The scraper structure is used to assist in pushing the sealing material at the outer drainage hole when the inner drainage tube 5 is pumped out by external force.

[0034] As one design example, such as Figure 4 As shown, the scraper structure includes several scraper rings 14 evenly spaced on the outer wall of the front end of the inner drainage tube 5. The scraper rings 14 are coaxially arranged with the inner drainage tube 5 and have a trumpet-shaped structure, with the trumpet openings of adjacent scraper rings 14 facing opposite directions. As another design example, such as Figure 5 As shown, the scraper structure includes several triangular scraper strips 15 disposed on the outer wall of the front end of the inner drainage tube 5. The several triangular scraper strips 15 are evenly spaced along the circumferential direction of the outer wall of the front end of the inner drainage tube 5.

[0035] Preferably, the diameter of the external drainage hole 3 is smaller than the diameter of the internal drainage tube 5, so as to ensure that impurities drawn in from the outside can pass smoothly through the internal drainage tube 5.

[0036] According to one example of this utility model, a clip is provided on the outer wall of the front end of the main drainage tube 1, and the front end of the irrigation tube 2 is detachably fixed at the clip; or, the outer wall of the front end of the main drainage tube 1 and the outer wall of the front end of the irrigation tube 2 are weakly connected by an ultra-thin medical PVC strip. In this embodiment, the irrigation tube 2 is designed to be detachable from the main drainage tube 1, and can be removed after surgery as needed, making the entire tube a simpler ordinary abdominal drainage tube, which is beneficial to the patient's recovery.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature.
