Description

[Technical field]

[0001] The utility model relates to the technical field of medical instruments, in particular to the technical field of gastric tubes. [Background technology]

[0002] At present, clinically, all patients who cannot take food through the mouth or who need gastric lavage need to have a gastric tube inserted, through which clean water, food or cleaning agent are injected, or gastric juice after cleaning is extracted through the gastric tube; when in use, the gastric tube enters the human body through the nasal cavity, and then passes through the esophagus, so that one end of the gastric tube is inserted into the patient's stomach, so that clean water, food or cleaning solution is injected into the stomach through the gastric tube, or gastric juice is extracted.

[0003] The end of an existing gastric tube is often sealed by a plug. A side hole is provided near the end of the gastric tube, and a recessed area is formed between the side hole and the plug. Gastric juice or food residues are likely to remain in the recessed area. When the gastric tube is pulled out, these gastric juice and food residues will gradually fall into the esophagus and nasal cavity due to shaking and other reasons, which will cause strong stimulation to the human body and cause normal physiological reactions such as nausea and vomiting. In addition, gastric juice can easily burn the esophagus and nasal cavity, causing harm and pain to the patient, which is not conducive to the patient's recovery. [Utility Model Content]

[0004] The utility model aims to solve the problems in the prior art and proposes a stomach tube which is not easy to have residues, so that gastric juice or food residues are not easy to remain in the stomach tube, and the esophagus and nasal cavity are not easy to be stimulated when the stomach tube is withdrawn.

[0005] To achieve the above-mentioned purpose, the utility model proposes a gastric tube that is not prone to residues, including a main body, a plugging head, and a side hole. The end of the main body is plugged with a plugging head, and the plugging head is composed of a first plugging body and a second plugging body of an integrated structure. The first plugging body is located outside the main body and abuts against the end of the main body, and the second plugging body is inserted into the main body. The main body is provided with a plurality of side holes, and the side holes are close to the end of the main body. When the main body is vertically arranged with the end facing downward, the lowest point of the upper end surface of the second plugging body is not lower than the lowest point of the side hole.

[0006] Preferably, the upper end surface of the second plug body is a slope.

[0007] Preferably, the upper end surface of the second plug body is a conical surface convex toward the side away from the first plug.

[0008] Preferably, the hole wall of the side hole expands outward from the inner side of the main body to the outer side of the main body.

[0009] Preferably, the outer wall of the main body is covered with a balloon, an inflation tube is fixed on the inner wall of the main body, one end of the inflation tube penetrates the side wall of the main body and is connected to the balloon, the other end of the inflation tube penetrates the main body and is connected to a one-way valve, and the one-way valve is connected to a plug interface.

[0010] The beneficial effects of the utility model: the utility model sets the lowest point of the upper end surface of the second plug body to be not lower than the lowest point of the side hole, so that it is not easy for an area with residual gastric juice and food residues to form inside the gastric tube, and it is not easy for the gastric tube to bring gastric juice and food residues into the esophagus and nasal cavity when the gastric tube is withdrawn, and it is not easy to cause irritation to the esophagus and nasal cavity, so it is safer to use; the balloon can close the gate opened due to the insertion of the gastric tube, so as to prevent gastric juice from flowing into the esophagus through the gate, so it is safer and more reliable to use.

[0011] The features and advantages of the present invention will be described in detail through embodiments in conjunction with the accompanying drawings.

[0015] In the figure: 1-main body, 2-blocking head, 3-inflation tube, 10-side hole, 21-first plugging body, 22-second plugging body, 30-balloon, 31-check valve, 32-plug interface. [Specific implementation method]

[0016] See also Figure 1 The gastric tube of the utility model, which is not easy to have residues, comprises a main body 1, a plugging head 2, and a side hole 10. The end of the main body 1 is plugged with a plugging head 2, and the plugging head 2 is composed of a first plugging body 21 and a second plugging body 22 of an integrated structure. The first plugging body 21 is located outside the main body 1 and abuts against the end of the main body 1, and the second plugging body 22 is inserted into the main body 1. The main body 1 is provided with a plurality of side holes 10, and the side holes 10 are close to the end of the main body 1. When the main body 1 is vertically arranged with the end facing downward, the lowest point of the upper end surface of the second plugging body 22 is not lower than the lowest point of the side hole 10.

[0017] In order to facilitate gastric fluid to flow out from the side hole 10 , the hole wall of the side hole 10 expands outward from the inside of the main body 1 to the outside of the main body 1 .

[0018] The upper end surface of the second plug body 22 is an inclined surface.

[0019] Embodiment 2:

[0020] See also Figure 2 On the basis of the first embodiment, the outer wall of the main body 1 is covered with a balloon 30, and an inflation tube 3 is fixed on the inner wall of the main body 1. One end of the inflation tube 3 penetrates the side wall of the main body 1 and is connected with the balloon 30, and the other end of the inflation tube 3 penetrates the main body 1 and is connected with a one-way valve 31. The one-way valve 31 is connected with an insertion port 32, and the syringe can be inserted into the insertion port 32. When the syringe is inserted into the insertion port 32, the one-way valve 31 can be pushed open to make it in an open state.

[0021] Embodiment three:

[0022] See also Figure 3 In order to allow gastric juice to flow out better, the upper end surface of the second plugging body 22 is no longer an inclined surface, but is set to a conical surface protruding away from the first plugging head 2.

[0023] Working process of this utility model:

[0024] During operation of the gastric tube of the utility model which is not easy to have residues, after the gastric tube is inserted into place, a syringe is inserted into the insertion port 32, and then gas is filled into the balloon 30 with the syringe to open the balloon, which blocks the esophagus, making it difficult for gastric juice to flow into the esophagus through the esophagus. When the gastric tube needs to be pulled out, the gas in the balloon 30 is extracted with a syringe, and then the gastric tube is slowly pulled out. Since the lowest point of the upper end surface of the second plug body 22 is not lower than the lowest point of the side hole 10 when the main body 1 is vertically arranged with the end facing downward, gastric juice or food residues are not easy to remain in the gastric tube, and the esophagus and nasal cavity are less stimulated when the gastric tube is pulled out, so it is safer and more reliable to use.

[0025] The above embodiments are intended to illustrate the present invention, not to limit the present invention. Any solution that is a simple transformation of the present invention falls within the protection scope of the present invention.
