Description
Technical Field
The utility model belongs to the technical field of medical instruments, and particularly relates to a stomach tube.
Background
Gastric tubes are commonly used to pump gases and fluids from the stomach for intragastric decompression or lavage, and may be used to inject fluids into the stomach to provide the patient with the necessary nutrients or medications to complete the treatment of the patient's stomach.
The utility model patent CN2465735Y discloses a bidirectional intestinal canal, wherein a partition wall is arranged in a cavity of a canal body, and the partition wall divides the cavity in the canal body into a long canal pipe and a short canal pipe with different lengths. Wherein the length of the short passage pipe is consistent with the length of the existing gastrointestinal decompression pipe, and the short passage pipe mainly completes the task of the gastrointestinal decompression pipe; the other long passage pipe can reach the jejunum through the pylorus, the duodenum and the ligament of dropwiser so as to provide nutrition for the jejunum, and the utility model can simultaneously complete the tasks of reducing the pressure of the intestines and the stomach and providing nutrition for the jejunum by only arranging one pipe in a patient. While the above patent is capable of simultaneously accomplishing the tasks of reducing gastrointestinal pressure and providing nutrition to the jejunum by implanting a single tube into the patient, the patent still has some problems: (1) When the gastrointestinal decompression suction of the gastric fluid is stopped, the residual fluid in the short passage flows back into the stomach; (2) The gastric juice is largely sucked away by the continuous decompression suction process in the stomach, so that the gastric juice is largely lost; (3) Food residues in the stomach enter the pipeline through the side holes on the pipeline wall in the gastrointestinal decompression process, so that the pipeline is easy to be blocked, and a large amount of liquid enters the stomach again when the pipeline is flushed by liquid such as normal saline, thereby increasing the pressure in the stomach.

In order to make the technical solution of the present utility model better understood by those skilled in the art, the technical solution of the present utility model will be clearly and completely described below with reference to the accompanying drawings, and based on the embodiments in the present application, other similar embodiments obtained by those skilled in the art without making creative efforts should fall within the scope of protection of the present application. In addition, directional words such as "upper", "lower", and the like, used in the following embodiments are merely directions with reference to the drawings, and thus, the directional words used are intended to illustrate, not limit, the utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying a relative importance or implicitly indicating the number of technical features indicated.
Referring to fig. 1-3, a gastric tube includes an intragastric decompression tube 1 and a jejunal nutrition tube 2 nested within the intragastric decompression tube 1. Wherein the upper and lower ends of the jejunal feeding tube 2 protrude from the upper and lower ends of the intragastric decompression tube 1, respectively. The upper end of the gastric decompression tube 1 is sealed with the upper side wall of the jejunum nutrition tube 2 into a whole, and the lower end of the gastric decompression tube 1 is sealed with the lower side wall of the jejunum nutrition tube 2 into a whole, so that the gastric decompression tube 1 and the jejunum nutrition tube 2 form a sleeve structure similar to a pipeline, and the gastric decompression tube 1 and the jejunum nutrition tube 2 are conveniently implanted into the stomach intestine of a patient as one pipeline, thereby reducing uncomfortable feeling caused to the patient by implantation of multiple times or multiple pipelines. The whole stomach tube composed of the gastric decompression tube 1 and the jejunum nutrition tube 2 is divided into four sections from top to bottom as shown in fig. 1, namely an oral cavity food tube section 100, a gastric inner section 200, a duodenal section 300 and a jejunum section 400 in sequence.
The upper end of the intragastric decompression tube 1 is connected with an upper intragastric decompression tube 3 which is used for being connected with a suction device to perform negative pressure suction so as to achieve the purpose of decompression.
With reference to fig. 1-3, the side wall of the intragastric decompression tube 1 located in the intragastric section is provided with a plurality of intragastric decompression drainage side holes 4, the intragastric decompression drainage side holes 4 are integrally located in the intragastric decompression tube 1, the intragastric decompression tube 1 is communicated with the outside, and the intragastric decompression drainage side holes 4 are internally provided with a second one-way valve 5. When the suction device is started, negative pressure is formed in the intragastric decompression tube 1, the second one-way valve 5 is opened under the action of the negative pressure, and gas and liquid in the stomach and intestine part enter the intragastric decompression tube 1 through the intragastric decompression drainage side hole 4 and the second one-way valve 5 and are sucked into the suction device. When the suction device is stopped, the second one-way valve 5 is closed, and if the liquid remains in the intragastric decompression tube 1, the liquid will not flow back to the stomach after the second one-way valve 5 is closed. The lower end of the intragastric decompression tube 1 is also provided with a first one-way valve 8, wherein the first one-way valve 8 is positioned at the jejunum section 300, the second one-way valve 5 is opened under the action of gastric juice pressure when negative pressure suction is not performed, gastric juice enters the intragastric decompression tube 1, then the first one-way valve 8 is opened under the action of gastric juice, and part of gastric juice is drained into jejunum through the first one-way valve 8, so that gastric juice is prevented from being completely sucked away in the continuous suction process, and a large amount of gastric juice is lost.
The side wall of the jejunum nutrition tube 2, which is close to the lower end of the jejunum nutrition tube, is provided with a plurality of jejunum nutrition side tubes 6, the jejunum nutrition side tubes 6 are integrally positioned in the jejunum nutrition tube 2, a third one-way valve 7 is arranged in the jejunum nutrition side tubes 6, and the third one-way valve 7 is positioned at the jejunum section 300. When the nutrition is injected into the jejunum nutrition tube 2, the third one-way valve 7 is opened under a certain pressure, and the nutrition is injected into the gastrointestinal part through the jejunum nutrition side tube 6 and the third one-way valve 7. In addition, the lower end of the jejunum nutrition tube 2 is designed into an arc structure, so that the jejunum nutrition tube 2 can be conveniently inserted into the jejunum part to directly supply nutrition.
It should be noted that the arrangement of the gastric decompression drainage side hole 4 and the jejunum nutrition side tube 6 shown in fig. 1 and 3 is only one embodiment of the present utility model, and those skilled in the art may select other arrangements to achieve the best suction and injection effects.
In addition, the gastric decompression tube 1 and the jejunum nutrition tube 2 are acid-resistant tubes, so that the gastric decompression tube and the jejunum nutrition tube cannot be corroded by gastric juice.
