[0036] Example

[0037] See also Figure 1-7 The present invention is a clinical ascites drainage device for gastroenterology, including a combined ascites drainage device, wherein the combined ascites drainage device includes a mobile cart 100, a liquid storage tank 300 and a filter box 400 loaded in the middle of the mobile cart 100, a drainage pipeline 500 connected to the filter box 400, and a controller 200 loaded on the upper part of the mobile cart 100. All components work together to form a complete ascites drainage system. The mobile cart 100 provides a basis for mobility and stability for the entire system. The liquid storage tank 300 and the filter box 400 are responsible for storing and purifying ascites, respectively. The drainage pipeline 500 establishes a safe passage from the patient to the filter box 400. The controller 200 coordinates the operation between the various components to ensure that the entire drainage process is efficient, safe, and controllable, which not only optimizes the performance of the combined ascites drainage device, but also improves the efficiency and quality of clinical work in gastroenterology.

[0038] The filter box 400 includes a box body 401, transparent visual panels 402 embedded on both sides of the box body 401, support plates 403 fixed in layers inside the box body 401, and a coarse filter element 404 and a fine filter element 405 arranged between adjacent support plates 403, wherein the coarse filter element 404 is located on the upper part of the fine filter element 405, and a water permeable hole 403a is opened in the middle of the support plate 403, wherein the water permeable hole 403a is symmetrically conical, the coarse filter element 404 is composed of multiple layers of non-woven fabrics, and the fine filter element 405 is composed of a polymer microporous filter membrane, and the ascites first passes through the coarse filter element 404. The filter element 404 removes larger particulate matter, and then continues to flow downward through the fine filter element 405, which is composed of a polymer microporous filter membrane and can capture finer impurities. The transparent visual plate 402 makes the filtering process intuitive and easy to monitor, thereby achieving effective purification of ascites, improving sample quality, reducing subsequent processing steps, and facilitating observation of the filtering status. The support plate 403 is used for the installation of the coarse filter element 404 and the fine filter element 405. The symmetrical conical water-permeable holes 403a opened in the middle can ensure that the ascites passes through the coarse filter element 404 and the fine filter element 405 evenly.

[0039] A connection terminal is provided at the upper part of one side of the box body 401, and the bottom of the other side of the box body 401 is connected to the bottom of the liquid storage tank 300 via a connecting pipe 700;
