Abstract
Description
Technical Field
[0001] This utility model relates to the field of gastrostomy tube technology, specifically a percutaneous gastric decompression and enteral nutrition device. Background Technology
[0002] A gastrostomy is suitable for patients who are unable to eat orally for a long period of time due to various reasons, including difficulty swallowing or eating, malignant tumors causing compression, tracheotomy, and neurological disorders and anorexia nervosa. A jejunal feeding tube, generally referring to a nasojejunal feeding tube, is a medical device that delivers nutrients directly into the small intestine, bypassing the stomach, thereby providing nutritional support. It is suitable for people with gastrointestinal motility disorders or esophageal reflux, and can also be used for gastrointestinal decompression and postoperative nutritional support.
[0003] However, existing gastrostomies and enterostomies have varying degrees of defects, such as: insufficient gastric motility, pyloric stenosis, and retention of gastric contents caused by tumors; the floating of the jejunal feeding tube back into the gastric cavity and the reflux of gastric contents leading to respiratory infections. Utility Model Content
[0004] The purpose of this invention is to provide a percutaneous gastric decompression and enteral nutrition device that can provide nutrition to the gastrointestinal tract and avoid the problems of content retention and reflux that exist in traditional gastrointestinal fistulas.
[0005] The objective of this utility model is achieved through the following technical solution:
[0006] A percutaneous gastric decompression and enteral nutrition device includes a main tube, on the outside of which a body surface fixation plate and a balloon are fixedly connected, and on the inside of which a multi-channel component is provided.
[0007] The multi-pathway component includes a balloon channel, a jejunal inlet channel, and a gastric channel. The balloon channel, jejunal inlet channel, and gastric channel all extend out of the rear end of the main tube. The balloon channel is connected to the balloon. A gastric outlet, which is connected to the gastric channel, is opened on the outer side of the main tube. A jejunal outlet channel is provided inside the main tube. The jejunal outlet channel is connected to the jejunal inlet channel. A plurality of jejunal side holes, which are connected to the jejunal outlet channel, are opened on the outer wall of the main tube.
[0008] Compared with the prior art, the advantages of this utility model are:
[0009] 1. This utility model includes two lumens, a jejunal inlet channel and a gastric channel, which can deliver nutrients and chyme, forming a dual perfusion pathway. The gastric channel delivers nutrients to the stomach cavity through the gastric outlet for gastric nutrition or decompression drainage. The jejunal inlet channel delivers nutrients directly to the descending part of the duodenum through the jejunal outlet channel and jejunal side opening across the pylorus. The multi-lumen and multi-channel design can meet different nutrient delivery needs, realize nutrient diversion, avoid content retention and reflux, and improve the diversity and effectiveness of nutrient supply.
[0010] 2. In this utility model, by setting up a balloon and a balloon channel, the balloon is inflated and then contacts and limits the gastric wall, thereby effectively preventing the main tube from shifting. In addition, the surface fixation piece is fixed to the inside of the abdominal wall, which enhances the anchoring stability of the abdominal wall and further avoids the shifting of the entire device, ensuring the stability of the tube and reducing the occurrence of shifting or blockage.

[0015] The present invention will now be described in detail with reference to the accompanying drawings and embodiments:
[0016] like Figure 1-3 The image shown is a schematic diagram of an embodiment of a percutaneous gastric decompression and enteral nutrition device provided by this utility model:
[0017] A percutaneous gastric decompression and enteral nutrition device includes a main tube 1, with a body surface fixation plate 5 and a balloon 6 fixedly connected to the outside of the main tube 1, and a multi-channel component disposed inside the main tube 1.
[0018] The multi-path component includes a balloon channel 2, a jejunal inlet channel 3, and a gastric channel 4. The balloon channel 2, jejunal inlet channel 3, and gastric channel 4 all extend out of the rear end of the main tube 1. The balloon channel 2 is connected to the balloon 6. A gastric outlet 7 connected to the gastric channel 4 is provided on the outer side of the main tube 1. A jejunal outlet channel 8 is provided inside the main tube 1. The jejunal outlet channel 8 is connected to the jejunal inlet channel 3. A plurality of jejunal side holes 9 connected to the jejunal outlet channel 8 are provided on the outer wall of the main tube 1.
[0019] The body surface fixation piece 5 is located on the posterior side of the balloon 6, and the balloon 6 is located on the posterior side of the gastric outlet 7.
[0020] The front end of the jejunal output channel 8 extends to the front of the main body tube 1, and the jejunal side hole 9 is correspondingly provided at the front end of the main body tube 1.
[0021] Multiple jejunal side holes 9 are scattered and interspersed at the front end of the main tube 1.
[0022] The surface fixation patch 5 is a polypropylene patch surface fixation patch, and the polypropylene patch material has good tissue compatibility and anti-infection ability.
[0023] The body surface fixation piece 5 has a ring-shaped support foot 51 on its front side.
[0024] Preferably, the body surface fixing piece 5 and the annular support leg 51 are integrally formed.
[0025] The working principle of this utility model is roughly as follows:
[0026] Inflation of the balloon 6 through the balloon channel 2 causes the balloon 6 to abut against and be positioned against the inner wall of the stomach. The polypropylene surface fixation sheet 5 enhances the anchoring stability of the abdominal wall and reduces the risk of infection. The gastric cavity channel 4 and the jejunal inlet channel 3 form a dual perfusion pathway. The former provides gastric nutrition or decompression drainage through the gastric cavity outlet 7, while the latter delivers nutrition directly to the descending part of the duodenum across the pylorus through the jejunal outlet channel 8 and the jejunal side hole 9, effectively avoiding gastric retention.
[0027] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
