[0001] The invention relates to the field of drainage tubes, in particular to an all-in-one drainage tube. Background Art

[0002] In medical practice, after abdominal surgery or treatment, different amounts of fluid (such as blood, exudate, etc.) may accumulate in the patient's abdominal cavity. If these effusions are not discharged in time, they may lead to infection, increased pain, and delayed recovery. Therefore, abdominal drainage has become an important part of postoperative management. At present, most of the commonly used abdominal drainage tubes in clinical practice are single-lumen designs, which are directly inserted into the abdominal cavity for drainage. In the case of multiple effusions in the abdominal cavity, doctors often need to insert multiple drainage tubes.

[0003] In this traditional treatment method, the patient's body is often filled with drainage tubes, and each drainage tube needs to be equipped with a drainage bag to collect peritoneal fluid, which increases the patient's physical burden. It not only increases the patient's pain and infection risk, but also makes the nursing process more complicated. Therefore, an all-in-one drainage tube is proposed to address the above situation.

[0008] The outer wall of the side pipe joint is provided with a plurality of side through holes in a circular array so that the peritoneal fluid entering the side pipe joint can be discharged. When the side pipe joint is inserted into the first channel to complete the assembly, one end of the side pipe joint abuts against the blocking head so that the T-shaped rod shrinks into the T-shaped cavity, and the second channel is connected to the side through holes. The end of the side pipe joint away from the connecting head is sleeved with a side pipe.

[0009] Preferably, the side conduit has a first end and a second end, the first end is placed in the patient's body, and the second end is used to be plugged into and cooperated with the side tube connector to transport the peritoneal fluid in the patient's body to the side tube connector.

[0010] Preferably, the side pipe joint has a conical structure at one end that cooperates with the side pipe, and has anti-slip grooves on its surface. When the side pipe cooperates with the side pipe joint, the inner wall of the side pipe contacts the anti-slip grooves.

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 creative work are within the scope of protection of the present invention.

[0022] The following is combined with Figure 1 —8 further details of this application, The present application embodiment discloses an all-in-one drainage tube. Figure 1 - Figure 8 A multi-in-one drainage tube includes a main pipe 1 and a side pipe joint 9. The main pipe 1 is fixedly connected with an adapter 2, which is connected to the inside of the adapter 2. The adapter 2 is provided with at least three assembly holes 201 on a side away from the main pipe 1. The three assembly holes 201 are all connected to the inside of the adapter 2 to realize the transportation of peritoneal fluid. The three assembly holes 201 are all interference-fitted with connectors 3 for transporting peritoneal fluid. The connector 3 is a convex tube body.

[0023] A first channel 301 is provided on one side of the connector 3, a second channel 302 is provided inside the connector 3, a sealing groove 3020 is provided on the inner wall of the second channel 302, the first channel 301 is connected to the second channel 302, and a plurality of drainage holes 303 are provided in a circular array on the side of the connector 3 away from the first channel 301, and the drainage holes 303 are connected to the second channel 302.

[0024] An inner shell body 4 is provided inside the second channel 302, a T-shaped cavity 401 is provided on the inner shell body 4, an elastic member 5 is provided in the T-shaped cavity 401, a T-shaped rod 6 is fixedly connected to the elastic member 5, the T-shaped rod 6 is slidably fitted in the T-shaped cavity 401, a plugging head 7 is fixedly connected to one end of the T-shaped rod 6 passing through the outside of the T-shaped cavity 401, and an annular sealing ring 8 is fixedly connected to the end of the plugging head 7 away from the inner shell body 4.

[0025] The outer wall of the side pipe joint 9 is provided with a plurality of side through holes 903 in a circular array so that the peritoneal fluid entering the side pipe joint 9 can be discharged. When the side pipe joint 9 is inserted into the first channel 301 to complete the assembly, one end of the side pipe joint 9 abuts against the blocking head 7 so that the T-shaped rod 6 shrinks into the T-shaped cavity 401, and the second channel 302 is connected with the side through hole 903. The end of the side pipe joint 9 away from the connecting head 3 is sleeved with a side pipe 10.

[0026] Reference Figure 1 , Figure 2 and Figure 4The side conduit 10 has a first end and a second end. The first end is placed in the patient's body, and the second end is used to be plugged into and matched with the side pipe connector 9 to transport the peritoneal fluid in the patient's body to the side pipe connector 9.

[0027] In this embodiment, the first end transports the peritoneal fluid in the body out through the second end into the side pipe joint 9, and the peritoneal fluid can be transported to the connector 3 through the side pipe joint 9, and then transported to the main pipe 1 by the connector 3, and discharged through the main pipe 1.

[0028] Reference Figure 1 , Figure 2 , Figure 4 and Figure 8 The side pipe joint 9 has a conical structure at one end that cooperates with the side pipe 10, and its surface has anti-slip grooves. When the side pipe 10 cooperates with the side pipe joint 9, the inner wall of the side pipe 10 contacts the anti-slip grooves.

[0029] In the present embodiment, one end of the side pipe joint 9 is designed to be tapered to facilitate the assembly of the side pipe 10. At the same time, by providing anti-slip grooves, after the side pipe 10 is sleeved on the side pipe joint 9, the friction force after contact with the side pipe 10 can be increased, thereby improving the stability of the side pipe 10 after assembly.

[0030] Reference Figure 2 , Figure 4 and Figure 8 The side pipe joint 9 has an inner cavity, and one conical end of the side pipe joint 9 has an opening, and the side through hole 903 and the opening are both connected to the inner cavity.

[0031] In this embodiment, an opening is provided so that the peritoneal fluid transported from the side pipe 10 enters the inner cavity through the opening, and then the peritoneal fluid in the inner cavity can be discharged out of the side pipe joint 9 through the side through hole 903, and then discharged through the connector 3.

[0032] Reference Figure 1 , Figure 2 , Figure 4 , Figure 6 and Figure 8 A retaining ring 901 is provided on the outer wall of the side pipe joint 9 . When the side pipe joint 9 is assembled with the first channel 301 , the retaining ring 901 is in contact with the outer wall of the connector 3 .

[0033] In this embodiment, by providing a retaining ring 901, when assembling the side pipe joint 9, it can limit the side pipe joint 9 and also remind the side pipe joint 9 to be properly assembled, providing convenience for the staff in the assembly process.

[0034] Reference Figure 2 , Figure 4 , Figure 6 and Figure 8The outer wall of the side pipe joint 9 is also provided with an external thread 902, and the first channel 301 is provided with an internal thread 3010. When the side pipe joint 9 is inserted into the first channel 301, the external thread 902 and the internal thread 3010 cooperate with each other to realize the positioning of the side pipe joint 9.

[0035] In this embodiment, when assembling the side pipe joint 9, the side pipe joint 9 is inserted into the first channel 301 and rotated. The threaded cooperation between the external thread 902 and the internal thread 3010 ensures the stability of the side pipe joint 9 after installation and ensures that it will not loosen during use.

[0036] Reference Figure 1 , Figure 2 and Figure 4 The main pipeline 1 and the side pipeline 10 are both made of either a silicone tube or a latex tube.

[0037] In this embodiment, after the soft side tube 10 is inserted into the patient's body, the patient's foreign body sensation is reduced.

[0038] Reference Figure 5 and Figure 6 The elastic member 5 is a spring or a spring.

[0039] In this embodiment, the elastic member 5 can be provided to allow the side pipe joint 9 to rebound after being removed, so that the plugging head 7 completes the plugging process.

[0040] The plugging head 7 is in a T-shape, and both the plugging head 7 and the side pipe joint 9 can be made of plastic material.

[0041] Working principle: When in use, according to actual use requirements, select the corresponding number of side pipes 10 for assembly. During installation, first insert one end of the side pipe joint 9 into the first channel 301, and rotate the side pipe joint 9 clockwise so that the external thread 902 and the internal thread 3010 complete the threaded fit to realize the positioning of the side pipe joint 9. During the assembly process of the side pipe joint 9, the side pipe joint 9 will extend from the first channel 301 into the second channel 302. During this process, the end of the side pipe joint 9 will contact the plugging head 7. As the side pipe joint 9 rotates and moves toward the inside of the second channel 302, the plugging head 7 moves accordingly. The movement of the plugging head 7 causes the T-shaped rod 6 to slide inside 402 and squeeze the elastic member 5. The elastic member 5 undergoes elastic deformation. When the side through hole 90 After the side pipe 10 is completely connected with the second channel 302, at this time, the retaining ring 901 contacts the outer wall of the connector 3, which means that the side pipe joint 9 is assembled completely, and then one end of the side pipe 10 is inserted from the tapered end of the side pipe joint 9, and the side pipe 10 is connected with the side pipe joint 9 by utilizing the material characteristics, and the end of the side pipe 10 away from the side pipe joint 9 is inserted into the patient's body, and the peritoneal fluid is discharged into the side pipe joint 9 through the side pipe 10, enters the inner cavity of the side pipe joint 9 through the opening at the end of the side pipe joint 9, and then is discharged into the second channel 302 through the side through hole 903. The peritoneal fluid entering the second channel 302 is discharged into the interior of the adapter 2 through the plurality of drainage holes 303, and then discharged into the drainage bag through the main pipe 1 connected with the adapter 2 for collection.

[0042] According to the actual situation, when reducing the number of side pipes 10 used, the side pipe joint 9 is rotated counterclockwise and then taken out from the first channel 301. During this process, the side pipe joint 9 no longer conflicts with the plugging head 7. Under the reset action of the elastic member 5, the T-shaped rod 6 slides toward one end of the first channel 301, so that the plugging head 7 fits the inner wall of the second channel 302. At the same time, the annular sealing ring 8 is inserted into the sealing groove 3020 to improve the sealing performance, thereby effectively preventing other side pipe joints 9 from entering the adapter 2 during use. The peritoneal fluid leakage ensures the continuity and safety of the drainage process. The above shows and describes the basic principles, main features and advantages of the present invention. The technicians in this industry should understand that the present invention is not limited to the above embodiments. The above embodiments and descriptions only illustrate the principles of the present invention. Without departing from the spirit and scope of the present invention, the present invention will also have various changes and improvements, and these changes and improvements fall within the scope of the present invention to be protected.
