Description

Technical Field

[0001] The utility model relates to the technical field of gastric tubes, and specifically relates to a gastric tube for preventing food reflux. Background Art

[0002] A gastric tube is inserted through the nostril, passes through the pharynx and esophagus to reach the stomach through the gastric tube. It is mostly used to aspirate gastric juice, wash the stomach in case of acute poisoning, and can also be used to inject liquid into the stomach to provide the patient with necessary food and nutrition. During nursing, attention should be paid to avoiding contamination of the gastric tube and the gastric tube from slipping out, resulting in aspiration.

[0003] Through patent retrieval, it is found that an anti-reflux gastric tube with the publication number of CN217339433U can, after inserting the gastric tube into the patient's stomach, inflate the inflatable airbag through the inflating component. After inflation, the inflated airbag expands to block the patient's esophagus, thereby preventing the patient from suffering from discomfort or increased gastric pressure from causing gastric content reflux. In the above-mentioned comparative document, since the airbag is directly fixed on the surface of the gastric tube, when inflated, the airbag expands and unfolds. Since there is no limiting structure outside the airbag, the airbag will expand outwards and may not be able to completely close the inside of the gastric tube. Content of the Utility Model

[0004] Aiming at the deficiencies of the prior art, the utility model provides a gastric tube for preventing food reflux, and solves the problems mentioned in the above background.

[0005] The utility model provides the following technical solutions: including: a gastric tube main body,

[0006] Also including:

[0007] A limiting sleeve, fixed on the surface of the gastric tube main body, and an airbag ring is attached to the inner wall of the groove of the limiting sleeve;

[0008] An inflation tube, installed inside the gastric tube main body, one end of the inflation tube is communicated with the airbag ring, and the other end of the inflation tube is communicated and connected with a communicating tube.

[0009] Furthermore, a reinforcing sleeve ring is fixed outside the gastric tube main body, and the outer wall of the communicating tube is fixed to the surface of the reinforcing sleeve ring.

[0010] Furthermore, the outer diameter of the limiting sleeve is larger than the outer diameter of the gastric tube main body, and the limiting sleeve is annular.

[0011] Furthermore, a three-way tube is arranged on one side of the reinforcing sleeve ring, and a sleeve is rotatably sleeved outside one end of the three-way tube.

[0012] Furthermore, a matching thread part is arranged between the outside of the communicating tube and the inside of the sleeve, and an inflation cylinder is fixed at the center of the three-way tube.

[0013] Further, a pressure measuring airbag is provided on one side of the three-way pipe, and an insertion pipe inserted into the three-way pipe is provided at the front end of the pressure measuring airbag.

[0014] Compared with the prior art, the utility model has the following beneficial effects:

[0015] In this application, a limiting sleeve with a larger radius size is fixedly arranged on the surface of the gastric tube main body, and a group of airbag rings are arranged around the limiting sleeve. When inflated externally, the airbag rings expand inwards under the restriction of the limiting sleeve, so that the airbag rings block the channel of the gastric tube main body. Compared with the comparative document, the expansion direction of the airbag rings is restricted during inflation, and the sealing performance of blocking the channel of the gastric tube main body is higher, and the effect of preventing food reflux is better.

[0021] The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0022] Please refer to Figures 1-4, including: a gastric tube body 1, a limiting sleeve 2 is fixedly arranged on the surface of the gastric tube body 1. During use, the gastric tube body 1 and the limiting sleeve 2 are inserted along the nasal cavity, and the front ends of the limiting sleeve 2 and the gastric tube body 1 are passed through the cardiac orifice and into the stomach. A balloon ring 3 is attached to the inner wall of the groove of the limiting sleeve 2. The balloon ring 3 is annular, and the outer wall of the balloon ring 3 fits with the inner wall of the limiting sleeve 2. The outer diameter of the limiting sleeve 2 is larger than the outer diameter of the gastric tube body 1, which can minimize the influence on the inner channel of the gastric tube body 1 when the balloon ring 3 is in a non-inflated state. An air charging tube 4 fixedly connected to the gastric tube body 1 is arranged inside the gastric tube body 1. One end of the air charging tube 4 communicates with the balloon ring 3. Gas is filled into the balloon ring 3 through the air charging tube 4. As the gas enters the balloon ring 3, the balloon ring 3 will expand. Under the restriction of the limiting sleeve 2, the balloon ring 3 expands inward, and finally the channel of the gastric tube body 1 is blocked and closed to prevent food from flowing back along the channel of the gastric tube body 1.

[0023] A reinforcing sleeve ring 5 with an annular structure is fixedly arranged on the outer wall of the gastric tube body 1. A connecting pipe 6 is fixedly arranged on the outer wall of the reinforcing sleeve ring 5. The inside of the connecting pipe 6 is hollow, and one end of the connecting pipe 6 close to the cavity of the gastric tube body 1 is connected to the air charging tube 4, so that gas can enter the air charging tube 4 along the connecting pipe 6. A three-way pipe 7 is arranged on one side of the reinforcing sleeve ring 5. A sleeve 8 is rotatably sleeved on the outer side of one end of the three-way pipe 7. Matching thread parts are arranged between the outside of the connecting pipe 6 and the inside of the sleeve 8. The sleeve 8 is butted at the pipe orifice of the connecting pipe 6, and then the sleeve 8 is gradually sleeved on the outside of the connecting pipe 6 by using the threaded connection between the sleeve 8 and the connecting pipe 6, and finally the front end of the connecting pipe 6 is communicated with the three-way pipe 7. An air charging cylinder 9 is fixedly arranged at the center of the three-way pipe 7. A pressure measuring airbag 11 is arranged on one side of the three-way pipe 7. A plug-in pipe 10 inserted into the three-way pipe 7 is arranged at the front end of the pressure measuring airbag 11. The connection mode between the plug-in pipe 10 and the three-way pipe 7 also adopts a screw connection. Gas is injected from the air charging cylinder 9. The gas is introduced into the pressure measuring airbag 11 and the balloon ring 3 through the three-way pipe 7 and the air charging tube 4. The expansion of the pressure measuring airbag 11 is used to judge the expansion and air leakage conditions of the balloon ring 3.

[0024] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
