Abstract
Description
Technical Field
[0001] This application relates to the field of drainage devices, and more particularly to a postoperative irrigation and drainage mechanism. Background Technology
[0002] The incidence of anastomotic leakage after radical esophagectomy is relatively high. Due to its special location, the anastomosis site is easily contaminated by secretions and contents from the digestive and respiratory tracts. This contamination often makes the anastomosis difficult to heal. Once contaminants flow into the pleural cavity and mediastinal esophageal bed through the fistula, if drainage is inadequate, it may lead to serious complications such as mediastinal infection and empyema.
[0003] Currently, there are some problems with drainage tubes in treating pleural infections caused by anastomotic leakage. Among them, the most prominent issue is the blockage of the drainage tube by contaminants. Because the contaminants flowing out of the anastomotic leakage may contain a large amount of fibrin, pus, and necrotic tissue, these substances can easily accumulate in the drainage tube, causing blockage and thus affecting the drainage effect.
[0004] Therefore, this application studies a postoperative irrigation and drainage mechanism that can minimize the blockage of the drainage tube and improve the drainage effect. Utility Model Content
[0005] In order to minimize the risk of clogging the drainage tube and improve the drainage effect, this application provides a postoperative irrigation and drainage device.
[0006] This application provides a postoperative irrigation and drainage device, which adopts the following technical solution:
[0007] A postoperative irrigation and drainage mechanism includes an irrigation tube and a drainage tube. The outer diameter of the irrigation tube is smaller than the inner diameter of the drainage tube. The irrigation tube includes an inlet section and an irrigation section that are interconnected. The central axes of the inlet section and the irrigation section are not on the same straight line. An inlet is provided on one side of the drainage tube. The inlet section extends out of the inlet. The irrigation section is located inside the drainage tube and is arranged along the inner wall of the drainage tube. The length direction of the irrigation section is consistent with the length direction of the drainage tube. Several side holes are provided on the side of the drainage tube along its length direction.
[0008] By adopting the above technical solution, during flushing, flushing fluid is introduced from the inlet and cleans the anastomosis along the flushing section. The flushing fluid also flushes the soft tissue cavities around the tube that are contaminated. The contaminated fluid flows back directly through the drain tube opening or is collected and returned to the drain tube cavity through the side holes around the drain tube. Continuous or pressurized flushing can be performed, thereby minimizing the risk of clogging the drain tube and improving the drainage effect.
[0009] Optionally, the flushing section includes a main flushing pipe and at least two branch flushing pipes, each of which is connected to one end of the main flushing pipe, and both the main flushing pipe and the branch flushing pipes are arranged along the inner wall of the drainage pipe.
[0010] By adopting the above technical solution, the flushing fluid can be distributed to the periphery of the pipe through multiple branch flushing pipes, resulting in a more uniform distribution of the flushing fluid.
[0011] Optionally, two branch flushing tubes are provided, respectively located on opposite sides of the inner wall of the drainage tube.
[0012] Optionally, a connecting pipe is provided between the branch flushing pipe and the main flushing pipe.
[0013] By adopting the above technical solution, the branch flushing tube can be easily extended to different angles and abutted against different positions on the inner wall of the drainage tube through the connecting tube.
[0014] Optionally, at least two sets of the side holes are formed along the sidewall of the drainage tube between adjacent branch flushing tubes.
[0015] Optionally, each pair of side holes in different groups is symmetrically arranged about the central axis of the drainage tube.
[0016] Optionally, the end of the branch flushing tube is flush with the end of the drainage tube.
[0017] Optionally, an external connector is fitted onto one end of the inlet.
[0018] In summary, this application includes at least one of the following beneficial technical effects:
[0019] 1. During flushing, flushing fluid is introduced from the inlet. The flushing fluid cleans the anastomosis along the flushing section and flushes the soft tissue cavities around the tube that are contaminated. The dirty fluid flows back directly through the drain tube opening or is collected and returned to the drain tube cavity through the side holes around the drain tube. The flushing fluid can be continuously flushed, thereby minimizing the risk of clogging the drain tube and improving the drainage effect.
[0020] 2. Multiple branch flushing pipes can distribute the flushing fluid around the pipe, resulting in a more uniform distribution of the flushing fluid. Attached Figure Description

[0028] The following is in conjunction with the appendix Figure 1-6 This application will be described in further detail.
[0029] This application discloses a postoperative irrigation and drainage mechanism. (Refer to...) Figure 1 The postoperative irrigation and drainage mechanism includes an irrigation tube 2 and a drainage tube 1. One end of the drainage tube 1 is connected to a drainage bag. The outer diameter of the irrigation tube 2 is smaller than the inner diameter of the drainage tube 1. The irrigation tube 2 includes an inlet section 21 and an irrigation section 22 that are interconnected. The central axes of the inlet section 21 and the irrigation section 22 are not on the same straight line. In some embodiments, an external connector 6 is fitted onto one end of the inlet section for connecting to an external water inlet device. An inlet 3 is provided on one side of the drainage tube 1, and the inlet section 21 extends out of the inlet 3. The inlet section 21 and the drainage tube 1 are sealed together. The irrigation section 22 is located inside the drainage tube 1 and is arranged along the inner wall of the drainage tube 1. The length direction of the irrigation section 22 is consistent with the length direction of the drainage tube 1, that is, the irrigation tube 2 extends along the length direction of the drainage tube 1 and is fixed to the inner wall of the irrigation tube 2. The side of the drainage tube 1 is provided with several side holes 5 evenly spaced along its length. The sewage can be directly returned through the drainage tube 1, or it can be collected and returned to the cavity of the drainage tube 1 through the side holes 5, so that the drainage can be better carried out and blockage can be avoided as much as possible.
[0030] During flushing, flushing fluid is introduced from the inlet 21. The flushing fluid is a clean 0.9% sodium chloride liquid. The flushing fluid cleans the anastomosis along the flushing section 22 and flushes the soft tissue cavities around the tube that are contaminated. The dirty water flows back directly through the opening of the drainage tube 1 or back into the cavity of the drainage tube 1 along the side hole 5. The contaminants are collected through the drainage bag. Continuous or pressurized flushing can be performed to minimize the blockage of the drainage tube 1 and improve the drainage effect.
[0031] Reference Figures 1-3 In some embodiments, the rinsing section 22 includes a main rinsing pipe 221 and at least two branch rinsing pipes 222. Each branch rinsing pipe 222 is connected to one end of the main rinsing pipe 221, and both the main rinsing pipe 221 and the branch rinsing pipes 222 are arranged along the inner wall of the drainage pipe 1. (The positional relationship between the main rinsing pipe 221 and the drainage pipe 1 is shown in...) Figure 2 and Figure 3 The positional relationship between branch flushing tube 222 and drainage tube 1 is shown in the figure. Figure 4 and Figure 5 The flushing fluid is delivered to various locations around the tube through different branch flushing tubes 222, which allows for more uniform cleaning of the tissue around the tube. The degree of contamination at the anastomotic fistula is reduced after flushing, thus reducing the incidence of infection in deep cavities. The cleaner soft tissue environment provides better conditions for fistula healing.
[0032] Reference Figure 4 and Figure 5 In some embodiments, two branch flushing tubes 222 are provided, respectively located on opposite sides of the inner wall of the drainage tube 1. That is, the two branch flushing tubes 222 are symmetrical along the central axis of the drainage tube 1, so that the tissue around the tube can be cleaned more evenly.
[0033] Reference Figure 6 In some embodiments, a connecting pipe 4 connects the branch flushing pipe 222 and the main flushing pipe 221. In this embodiment, the connecting pipe 4 has a "Y" shaped structure. The main flushing pipe 221 can be extended to different angles through the connecting pipe 4, so that the main flushing pipe 221 and the branch flushing pipe 222 can fit into different positions on the inner wall of the drainage pipe 1, so as to better flush the anastomosis.
[0034] Refer again Figure 4 In some embodiments, at least two sets of side holes 5 are provided along the side wall of the drainage pipe 1 between adjacent branch flushing pipes 222, so that drainage can be performed better.
[0035] In some embodiments, each pair of side holes 5 in different groups is symmetrically arranged about the central axis of the drainage tube 1. In this embodiment, two groups of side holes 5 are provided, which are respectively provided on the side wall of the drainage tube 1 between the two branch flushing tubes 222.
[0036] In some embodiments, the end of the branch flushing tube 222 is flush with the end of the drainage tube 1. It is important to consider whether the branch flushing tube 222, being too thin or too long, can prevent tubing from bending and hindering flushing during insertion, or whether the tubing is too short, resulting in poor flushing fluid distribution.
[0037] The implementation principle of a postoperative irrigation and drainage mechanism according to an embodiment of this application is as follows: During irrigation, irrigation fluid is flushed in from the water inlet 21. The irrigation fluid cleans the anastomosis along the irrigation section 22 and rinses the soft tissue cavities around the tube that are contaminated. The contaminated fluid flows back directly through the opening of the drainage tube 1 or is collected and returned to the cavity of the drainage tube 1 through the side hole 5 around the tube 1. The irrigation fluid can continuously and uninterruptedly irrigate, thereby minimizing the risk of clogging the drainage tube 1 and improving the drainage effect.
[0038] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
