Abstract
Description
Technical Field
[0001] This utility model belongs to the field of medical device technology, and specifically relates to a segmented inflatable support gastric tube. Background Technology
[0002] Anastomotic stricture after esophagectomy is a common complication in gastrointestinal surgery, and is currently treated clinically using endoscopic radial incision. This procedure involves making multiple radial incisions at the stricture site under endoscopic guidance, which can effectively widen the lumen diameter in a short period. However, current clinical data show that approximately 30%-40% of patients experience restenosis within 3 months postoperatively.
[0003] Traditional methods for preventing restenosis mainly rely on short-term postoperative balloon dilation or temporary placement of a silicone nasogastric tube for support. However, existing balloons require adjustment of their position according to the patient's individual needs, making them inconvenient to use and causing patient discomfort. Furthermore, existing balloons cannot be clearly observed under ultrasound, making it impossible to accurately assess the balloon's position and support status, thus compromising treatment effectiveness.
[0004] Therefore, a segmented inflatable gastric tube is needed. Utility Model Content
[0005] The purpose of this invention is to provide a segmented inflatable gastric support tube, thereby overcoming the shortcomings of existing balloon or gastric tube support for the esophagus. These shortcomings include the inconvenience of adjusting the balloon position according to the patient's condition, the inability to accurately observe the balloon's condition for adjustment, the potential for repeated balloon adjustments causing patient pain, and the poor support effect. The specific technical solution is as follows:
[0006] A segmented inflatable gastric tube includes a tubing and a feeding port connector. The feeding port connector is installed at one end of the tubing, and the other end of the tubing is a feeding port. The end of the tubing near the feeding port connector is provided with a scale.
[0007] It also includes: airbags, air supply pipes and one-way valves. The airbag array is installed on the outer wall of the pipeline, the air supply pipe is installed on the pipeline, one end of the air supply pipe is connected to the airbags, and the one-way valve is installed at the other end of the air supply pipe.
[0008] Preferably, the airbags are distributed within a range of 12-15 cm extending to both sides from the midpoint of the pipeline.
[0009] Preferably, the airbags are independent of each other, and each airbag is connected to an air supply tube.
[0010] Preferably, the gas pipeline circumferential array is installed on the inner side wall of the pipeline.
[0011] Preferably, marking rings are installed at both ends of the airbag, and the marking rings are made of a high-echo material.
[0012] Preferably, the spacing between the airbags is 1-2 cm.
[0013] Preferably, a conversion connector is installed at one end of the pipeline near the food inlet connector to consolidate and fix all gas supply pipes.
[0014] Preferably, the end of the air supply tube furthest from the airbag is marked with a sequence mark.
[0015] Compared with existing technologies, this utility model has the following beneficial effects:
[0016] 1. This utility model has multiple air bladders installed on the pipeline, each of which can be inflated and expanded independently. This allows for the selection of a specific air bladder for support based on the patient's condition, eliminating the need for repeated removal of the gastric tube for adjustment and reducing patient discomfort.
[0017] 2. Marking rings are installed at both ends of the airbag. The marking rings are made of high-echo material, so they can be clearly observed during B-ultrasound, which facilitates the evaluation of the airbag's support position and support effect, thereby ensuring the airbag's support effect.

[0024] 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.
[0025] Next, the working principle of this embodiment will be described in detail so that those skilled in the art can better understand this utility model:
[0026] A segmented inflatable gastric support tube includes a tube 1 and a feeding port connector 2. The feeding port connector 2 is installed at one end of the tube 1, and the other end of the tube 1 is the feeding port 3. The end of the tube 1 near the feeding port connector 2 is provided with a scale, which allows medical staff to accurately control the length of the tube 1 when using this application, so as to avoid causing discomfort to the patient.
[0027] An array of balloons 4 is mounted on the outer wall of tubing 1. An air delivery tube 5 is installed on tubing 1, with one end connected to the balloons 4 and a one-way valve installed at the other end. A fixed amount of air is injected into the air delivery tube through the one-way valve, causing the balloons 4 to inflate and support the esophagus. The one-way valve prevents air leakage from the balloons 4. The diameter of a typical human esophagus is 1-1.5 cm. The size of the balloons 4 in this application is similar to the esophageal balloon of a three-lumen two-balloon tube. Therefore, when inflating the balloons 4, 100-200 ml of gas can be injected depending on the diameter of the patient's esophagus. Since the volume of the air delivery tube 5 is very small, its impact on the overall structure is minimal and can be disregarded. The amount of gas injected is positively correlated with the esophageal diameter; 100 ml of gas is injected into the balloons 4 for a 1 cm diameter esophagus, and 200 ml of gas is injected into the balloons 4 for a 1.5 cm diameter esophagus, thus ensuring the supporting effect of the balloons 4. Gas is typically injected using a syringe, with markings on the syringe allowing medical staff to accurately inject the appropriate volume of gas. When it's necessary to release the gas from the airbag 4, simply remove the one-way valve.
[0028] Airbags 4 are distributed within a range of 12-15 cm extending to both sides from the midpoint of tube 1. Since the length of the esophagus is generally about 25 cm, the range of the corresponding airbags 4 is also about this range, ensuring full coverage of the esophagus area and providing precise support for any position.
[0029] The airbags 4 are independent of each other, and each airbag 4 is connected to an air supply tube 5. Each air supply tube 5 has a different length, allowing for the selection of the appropriate airbag 4 for inflation based on specific needs. The air supply tubes 5 are arranged in a circumferential array on the inner wall of the pipe 1, forming part of the pipe 1 itself. This minimizes the impact of the air supply tubes 5 on the diameter of the pipe 1 while ensuring smooth movement of food within the pipe 1. Furthermore, the uniform circumferential array of the air supply tubes 5 prevents one side of the pipe 1 from becoming too strong and difficult to bend, thus avoiding any impact on usability.
[0030] Marking rings are installed at both ends of the airbag 4. The marking rings are made of high-echo materials, such as stainless steel, titanium alloy and platinum-iridium alloy. The marking rings can be clearly observed when the patient is examined by ultrasound, which makes it easy to assess the support position and support status of the airbag 4, thereby ensuring the support effect of the airbag 4.
[0031] The spacing between the airbags 4 is 1-2 cm to avoid interference between the airbags 4 and the bend of the tube 1 when multiple airbags 4 are needed for support at the same time, which would cause the tube 1 to interfere with the esophagus and cause pain to the patient.
[0032] A conversion connector 6 is installed at the end of tubing 1 near the feeding port connector 2 to consolidate and fix all gas delivery tubes 5, facilitating management of all gas delivery tubes 5, promoting smooth operation, and improving work efficiency. Sequence markings are provided at the ends of gas delivery tubes 5 furthest from the cuff 4 to help medical staff identify the corresponding gas delivery tube 5 for the cuff 4, preventing errors.
[0033] In summary, when using this application, tube 1 can be inserted into the patient's esophagus, with one end of the outlet 3 entering the patient's stomach. Based on the surgical situation and the patient's condition, the appropriate insulated tube 5 is selected to inflate the balloon 4, allowing the balloon 4 to support the esophagus. An ultrasound is performed on the patient to observe and evaluate the support and effectiveness of the balloon 4. If the balloon 4 is found to be mispositioned, it can be deflated, and then the correct balloon 4 can be inflated again. After use, the balloon 4 is deflated first, and then tube 1 is removed.
