Description

Technical Field

[0001] This utility model relates to the field of medical device technology, and in particular to a novel improved gastric tube. Background Technology

[0002] In clinical practice, the placement of gastric tubes for diagnosis, treatment, and nutritional support is a common medical procedure for patients with dysphagia, gastrointestinal obstruction, coma, post-major surgery, or those requiring gastric lavage. Gastric tubes have been used clinically for a long time and have made significant contributions to the treatment of critically ill patients.

[0003] However, in actual clinical practice, the above-mentioned device has the following problems: because the gastric tube is a straight tube with a large diameter, it is in close contact with the larynx during indwelling, which can cause continuous friction, leading to larynx damage and edema, affecting airway patency. In severe cases, it can cause the glottis to be unable to open, or even cause suffocation, seriously threatening the patient's life. Summary of the Invention

[0004] To address the shortcomings of the existing technology, this invention provides a novel improved gastric tube that uses a flexible, thin tube to reduce friction when in contact with the larynx, thus avoiding larynx injury and edema.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a novel improved gastric tube, comprising an upper tube, a lower tube, a thin tube, an outer tube, a connecting tube, and a guidewire. The upper tube and the lower tube are connected by the thin tube, which is a flexible tube with a small diameter that can be expanded. The outer tube is fitted over the upper tube and can slide to the outside of the thin tube to limit its excessive expansion. One end of the connecting tube is connected to the upper tube, and the other end can be connected to a syringe for easy aspiration and nasogastric feeding. The guidewire can be inserted into the connecting tube, the upper tube, the thin tube, and the lower tube to guide insertion into the digestive tract.

[0006] Compared with the prior art, the advantages of this utility model are: the flexible and thin tube design at the contact point with the larynx reduces the friction area and intensity, the tube diameter can be expanded to a limited extent during nasogastric feeding, it is safe to use and does not affect the function, and avoids the disadvantages of friction causing larynx damage and edema affecting airway patency.

[0007] Figure 1 This is a three-dimensional structural diagram of the present invention.

[0008] Figure 2 This is a schematic diagram of the state during nasogastric feeding according to this utility model.

[0009] Figure 3 This is a three-dimensional structural diagram of the disassembled state of this utility model. Detailed Implementation

[0010] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments, but this is not intended to limit the present invention.

[0011] Example 1: As shown in the figure, a novel improved gastric tube includes an upper tube 3, a lower tube 5, a thin tube 4, an outer tube 2, a connecting tube 1, and a guidewire 6. The upper tube 3 and the lower tube 5 are connected by the thin tube 4, which is a flexible tube with a small diameter that can be expanded. The outer tube 2 is fitted over the upper tube 3 and can slide to the outside of the thin tube 4. One end of the connecting tube 1 is connected to the upper tube 3, and the other end can be connected to a syringe for easy aspiration and nasogastric feeding. The guidewire 6 can be inserted into the connecting tube 1, the upper tube 3, the thin tube 4, and the lower tube 5 to guide insertion into the digestive tract.

[0012] Example 2: As shown in the figure, the other structures are the same as in Example 1. The difference is that the outer tube 2 is slid from the upper tube 3 to the outside of the thin tube 4, and the thin tube 4 is completely inside the outer tube 2. The outer tube 2 can limit the excessive expansion of the thin tube 4. Nasogastric feeding is given by connecting the syringe to the connecting tube 1. The liquid enters the thin tube 4 through the upper tube 3. Under the action of pressure, the thin tube 4 expands inside the outer tube 2, and the diameter increases, which is conducive to the passage of liquid. The liquid enters the digestive tract through the lower tube 5 to complete nasogastric feeding. The tube is flushed with water, the pressure inside the thin tube 4 decreases, and the diameter shrinks back. The outer tube 2 is slid from the thin tube 4 to the outside of the upper tube 3. The thin tube 4 has a smaller contact area with the larynx, which reduces friction and avoids larynx damage and edema.

[0013] It is worth noting that the above description is only a preferred embodiment of this utility model and does not limit the scope of patent protection of this utility model. This utility model can also improve the materials and structure of the above-mentioned components, or replace them with technical equivalents. Therefore, all equivalent structural changes made based on the description and drawings of this utility model, or direct or indirect applications to other related technical fields, are similarly included within the scope of this utility model.
