Description

Technical Field

[0001] The present invention relates to the technical field of medical instruments, and in particular to a gastric tube which is anti-blocking and easy to flush. Background Art

[0002] Common gastric tubes currently available on the market consist of a single tube that drains gastric juices and food residues and allows for the infusion of food or nutrient solution. However, these single channels are prone to blockage, which is difficult to clear. Consequently, the tube must be removed, replaced, and reinserted, an invasive procedure. This unplanned removal and intubation can be detrimental to the patient. Summary of the Invention

[0003] The purpose of the present invention is to provide a gastric tube that is anti-blocking and easy to flush, thereby solving the problem of tube blockage during the infusion of nutrients or gastrointestinal decompression drainage, and avoiding secondary damage to the patient caused by unplanned extubation or intubation.

[0004] In order to achieve the above object, the present invention provides the following technical solutions: A gastric tube that is anti-blocking and easy to flush, comprising an inner tube and an outer tube, wherein the inner side of the gastric tube is the inner tube, the outer side of the inner tube is provided with the outer tube, the upper ends of the inner tube and the outer tube are separated from each other, and the lower ends of the inner tube and the outer tube are closed to each other; The inner tube includes an inner tube body, an opening, and a valve. The inner tube body is provided with a plurality of openings, and the openings are provided with valves. The outer tube includes an outer tube body, a side opening, and a lower end opening. The upper side wall of the outer tube body is provided with a side opening, and the lower side wall of the outer tube body is provided with the lower end opening. The position of the lower end opening is lower than the closed position of the inner tube and the outer tube.

[0005] Furthermore, the upper end is the nose end, and the lower end is the stomach end.

[0006] The beneficial effects of the present invention are: this application solves the problem of tube blockage that occurs when injecting nutrients or gastrointestinal decompression drainage by setting up an internal and external double tube and a valve structure, avoids secondary damage to the patient caused by unplanned extubation or intubation, reduces the pain of the patient caused by re-insertion of the gastric tube, and improves medical care efficiency. Its overall structure is simple, easy to operate, and significantly improves patient comfort.

[0007] The above description is only an overview of the technical solution of the present invention. In order to more clearly understand the technical means of the present invention and implement it according to the contents of the specification, the following is a detailed description of the preferred embodiments of the present invention with reference to the accompanying drawings.

[0012] The technical solution of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the embodiments described are only some embodiments of the present invention, not all embodiments. All other embodiments obtained by ordinary technicians in this field based on the embodiments of the present invention without making any creative efforts shall fall within the scope of protection of the present invention.

[0013] In the description of the present invention, it should be noted that the terms "center," "upper," "lower," "left," "right," "vertical," "horizontal," "inner," and "outer," etc., indicating orientations or positional relationships, are based on the orientations or positional relationships shown in the accompanying drawings and are intended solely to facilitate and simplify the description of the present invention. They are not intended to indicate or imply that the devices or components referred to must have, be constructed, or operate in a specific orientation, and therefore should not be construed as limitations on the present invention. Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0014] In the description of the present invention, it should be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" should be understood in a broad sense. For example, they may refer to fixed, detachable, or integral connections; mechanical or electrical connections; direct or indirect connections through an intermediate medium; and internal communication between two components. Those skilled in the art will understand the specific meanings of the above terms in the present invention based on the specific circumstances.

[0015] In addition, the technical features involved in the different embodiments of the present invention described below can be combined with each other as long as they do not conflict with each other.

[0016] See Figure 1 A preferred embodiment of the present application shows a gastric tube that is anti-blocking and easy to flush, comprising an inner tube 1 and an outer tube 2. The inner side of the gastric tube is the inner tube 1, and the outer tube 2 is provided on the outside of the inner tube 1. The upper ends of the inner tube 1 and the outer tube 2 are separated from each other, and the lower ends of the inner tube 1 and the outer tube 2 are closed to each other. The inner tube 1 includes an inner tube body 10, openings 11, and a valve 12. The inner tube body 10 is provided with a plurality of openings 11, and the openings 11 are provided with valves 12. The outer tube 2 includes an outer tube body 20, a side opening 21, and a lower end opening 22. The upper side wall of the outer tube body 20 is provided with a side opening 21, and the lower side wall of the outer tube body 20 is provided with a lower end opening 22. The position of the lower end opening 22 is lower than the closed position of the inner tube 1 and the outer tube 2.

[0017] The upper end is the nose end and the lower end is the stomach end.

[0018] When in use, the lower ends of the inner tube 1 and the outer tube 2 are inserted into the patient's stomach, the upper ends are fixed outside the nose, and the side opening 21 is also fixed outside the nose. The inner tube 1 is used for normal feeding and drainage. When blockage occurs, warm water is injected from the side opening 21. The warm water enters the inner tube 1 through the valve 12, thereby diluting and flushing the blockage.

[0019] In summary, the present invention provides a gastric tube that is anti-blocking and easy to flush. The device solves the problem of tube blockage that occurs when injecting nutrients or gastrointestinal decompression and drainage by setting up inner and outer double tubes and a valve structure, avoids secondary damage to the patient caused by unplanned extubation or intubation, reduces the pain of the patient caused by re-insertion of the gastric tube, and improves medical care efficiency. Its overall structure is simple, the operation is easy, and the patient's comfort is significantly improved.
