[0001] This utility model relates to the field of upper gastrointestinal fluid collection technology, specifically to an endoscopic upper gastrointestinal fluid segmented collection device. Background Technology

[0002] Gastrointestinal fluids are crucial specimens for detecting digestive system diseases. Sampling and analyzing their composition can aid in the diagnosis of Helicobacter pylori positivity, virulence, drug resistance, early gastric cancer, and intestinal diseases. The fluid components of the upper gastrointestinal tract (including the esophagus, stomach, and duodenum), such as gastric acid, bile, pancreatic juice, and mucus, are particularly significant for the diagnosis and treatment of various diseases. However, traditional methods for collecting gastric or duodenal fluid suffer from inaccurate sampling, inability to obtain fractional samples, and complex procedures. The development of an endoscopic upper gastrointestinal fluid fractional collection device aims to address these clinical challenges and provide a more reliable testing method for precision medicine.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please refer to Figures 1-5. This utility model provides a technical solution: an endoscopic upper gastrointestinal fluid segmentation collection device, including a collection bottle 1, a collection tube 2 installed on the upper end of the collection bottle 1, and a diversion component installed on the collection tube 2 to divert the liquid. The collection bottle 1 includes a plurality of collection cylinders 101 and a baffle plate 102. There are a plurality of baffle plates 102, each baffle plate 102 is distributed between two adjacent collection cylinders 101. The lower end of each baffle plate 102 is rotatably connected to the adjacent collection cylinder 101 through a connector, and the upper end of each baffle plate 102 is fixedly connected to the adjacent collection cylinder 101. A collection port 103 is opened on the lower end wall of the plurality of collection cylinders 101, and a collection port 204 is opened on the wall of the plurality of baffle plates 102.

[0021] During upper gastrointestinal fluid collection, endoscopic guidance is used to collect fluid from different anatomical locations (lower esophagus, gastric fundus, gastric antrum, duodenal bulb / descending part). First, the endoscope guides the collected upper gastrointestinal fluid through one of the collection tubes, 2, into the diversion assembly. Rotating the anti-slip handle 14 at the upper end of the fixed cylinder 6 rotates the diversion plate 7. Depending on the needs, the diversion port 9 on the diversion plate 7 is aligned with diversion ports 8, 9, or 10 on the wall of the fixed cylinder 6, thus diverting the fluid into collection tubes 11, 12, or 13, achieving initial diversion and collection. The fluid diverted through collection tube 13 then enters the collection bottle 1 through collection tube 2. Since the collection cylinder 101 of the collection bottle 1 has a collection port 103 at its lower end, and the barrier plate 102 has a collection port 104, and... The anti-foolproof strip 3 on the outer wall of the collection tube 101 can assist in aligning the holes to ensure that the liquid can accurately flow into the corresponding collection tube 101 as needed. The lower end of the barrier plate 102 is rotatably connected to the collection tube 101 through the connector of the protrusion 4 and the groove 5, which facilitates the operation of different collection tubes 101 during the collection process. The elastic transparent plate of the collection tube 101 wall makes it easy to observe the collection of liquid in each collection tube 101, and finally realizes the precise segmented collection of upper gastrointestinal fluid. The development of the endoscopic upper gastrointestinal fluid segmented collection device fills the gap of traditional methods in terms of precise sampling, dynamic monitoring and low-invasive operation. It not only improves the accuracy of disease diagnosis (such as GERD classification and bile reflux quantification), but also optimizes treatment evaluation (such as PPI efficacy monitoring) and further promotes scientific research progress (such as gastrointestinal microbe-host interaction research).

[0022] Each of the collection cylinders 101 has a fixed anti-fool strip 3 on its outer wall. Each anti-fool strip 3 is flush with the corresponding collection port 104 on the vertical plane. The anti-fool strip facilitates hole-to-hole alignment, making operation and collection easier. The collection cylinders 101 collect saliva, gastric juice and duodenal fluid separately.

[0023] The connector includes a protrusion 4 and a groove 5. The lower ends of the plurality of barrier plates 102 are integrally formed with protrusions 4. The upper inner walls of the plurality of collection cylinders 101 are provided with grooves 5. The protrusions 4 are rotatably disposed in the grooves 5. The walls of the plurality of collection cylinders 101 are all elastic transparent plates. The barrier plates 102 are configured to rotate relative to the collection cylinders 101, which facilitates the operation of different collection cylinders 101. At the same time, the elastic transparent plates facilitate the observation of the liquid collection in the collection cylinders 101.

[0024] There are two collection tubes 2. The diversion assembly includes a fixed cylinder 6 fixedly installed on the upper end of the collection tube 2, a diversion plate 7 rotatably installed on the inner wall of the fixed cylinder 6, a diversion port 8 and a diversion port 9 opened on the diversion plate 7, three diversion ports 10 equidistantly distributed on the wall of the fixed cylinder 6, and collection tubes 11, 12 and 13 installed in the three diversion ports 10. By rotating the diversion plate 7, the liquid can be diverted to different collection tubes to achieve segmented collection.

[0025] The collecting tube 4 13 is U-shaped, and its lower end is fixed inside the collecting tube 1 2 and connected to the collecting tube 1 2. The U-shaped design of the collecting tube 4 13 helps the liquid flow smoothly and collect.

[0026] The upper end of the fixed cylinder 6 is fixedly connected to an anti-slip handle 14. The diversion port 8 is connected to a collection tube 15. The upper end of the collection tube 15 passes through the anti-slip handle 14 and is rotatably connected to the anti-slip handle 14. The anti-slip handle 14 facilitates the operation of the diversion component. The rotatable connection between the collection tube 15 and the anti-slip handle 14 makes the diversion operation more flexible.

[0027] Finally, it should be noted that the above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
