Description

Technical Field

[0001] The utility model belongs to the technical field of gastric tubes, and in particular relates to an anti-reflux gastric tube. Background Art

[0002] Gastric tubes are mainly used for gastrointestinal nutrition and energy support for some gastrointestinal patients who are unable to eat independently in clinical practice. The gastric tubes currently used usually have a balloon fixed on the outer wall of the gastric tube body. The balloon is inflated to expand and block the gap, thereby preventing the reflux of gastric contents. However, a single balloon is used to block the gap between the outer wall of the gastric tube and the inner wall of the esophagus. The balloon is inflated for a long time to compress the esophageal and nasal mucosa, which will cause ulceration of the esophageal and nasal mucosa and easily cause erosion and necrosis of the esophageal and nasal mucosa. Utility Model Content

[0003] The utility model aims to overcome the shortcomings of the prior art and provide an anti-reflux gastric tube which can effectively prevent food from flowing back through the esophagus.

[0004] The utility model adopts the following technical solutions:

[0006] Furthermore, the water injector comprises a water injection syringe which can contain water and a piston push rod which can be movably arranged in the water injection syringe, and the piston push rod is connected to the water injection syringe by a threaded connection.

[0007] Furthermore, the piston push rod includes a push rod body, a piston head arranged at the front end of the push rod body and a threaded portion arranged on the piston head, and a threaded section cooperating with the threaded portion is arranged inside the water injection syringe.

[0008] Furthermore, the umbrella-shaped blocking ring comprises a plurality of first supporting cloths spaced apart along the outer circumference of the main pipe and a second supporting cloth disposed between two adjacent first supporting cloths, and the thickness of the first supporting cloth is greater than that of the second supporting cloth.

[0009] Furthermore, the main pipe also includes a plurality of side holes arranged at its lower part near the liquid food outlet, a cap arranged on one side of the liquid food injection port and capable of covering the liquid food injection port, and an arc-shaped protective pad arranged at the end of the liquid food outlet and capable of contacting the esophagus and stomach.

[0010] Furthermore, the first airbag tube is provided with a water injection valve, and the second airbag tube is provided with a connector connected to the water injector.

[0011] Furthermore, the main pipe and the auxiliary pipe are integrally formed, and the first airbag pipe, the second airbag pipe and the main pipe are not connected.

[0012] It can be seen from the above description of the utility model that compared with the prior art, the utility model has the following beneficial effects: the present application cooperates between the main tube and the auxiliary tube arranged on the main tube, and defines the specific structure of the auxiliary tube, so that when medical staff feed patients through a gastric tube, the airbag can be located in the stomach, the blocking member can be located at the connection port between the esophagus and the stomach, and water is injected into the airbag body and the support airbag respectively. After the airbag body is injected with water, it is spherical in the stomach and can block most liquid food. After the support airbag is injected with water, the umbrella-shaped blocking ring is opened to completely cover the connection port between the esophagus and the stomach, playing a secondary blocking role, and can effectively prevent food from refluxing through the esophagus. The umbrella-shaped blocking ring is made of soft rubber material, which has little pressure on the esophagus, reduces the compression on the esophagus, and avoids damage to the esophageal nasal mucosa.

[0013] Through the cooperation between the water injection syringe that can hold water and the piston push rod that can be movably arranged in the water injection syringe, when in use, water is injected into the support airbag little by little through the piston push rod, and the water intake of the support airbag can be accurately controlled;

[0014] By setting a plurality of side holes at the lower part of the main tube near the outlet of the liquid food, it is possible to effectively prevent the food and nutrient solution from flowing back through the main tube, and also facilitate the medical staff to make the injected food and nutrient solution flow to all parts of the stomach when feeding;

[0015] By arranging an arc-shaped protective pad at the end of the liquid food outlet that can contact the esophagus and the stomach, damage to the esophagus and the stomach can be reduced during the process of inserting the main tube into the stomach. BRIEF DESCRIPTION OF THE DRAWINGS
