Description

Technical Field

[0001] This utility model relates to the field of gastric tube technology, and in particular to a gastric tube assembly with an expanding and dispersing end pressure. Background Technology

[0002] In modern medicine, gastric tubes are commonly used medical devices for delivering medications, nutritional solutions, or performing gastrointestinal decompression. However, traditional gastric tubes have a significant problem during use: the end of the tube is in direct contact with the gastric mucosa, resulting in excessively concentrated pressure on the gastric mucosa, which can easily lead to gastric mucosal damage. Furthermore, the continuous pressure of the end of the tube on the stomach wall may damage mucosal blood vessels and cause gastric bleeding. Therefore, in order to disperse the pressure on the stomach from the end of the gastric tube, this invention proposes a gastric tube assembly with an expansion mechanism to disperse the pressure at the end. Utility Model Content

[0003] The purpose of this invention is to provide a gastric tube assembly with expanded and dispersed end pressure to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a gastric tube assembly with expandable and dispersed end pressure, comprising a gastric tube body, the gastric tube body comprising an external section and an insertion section, the end of the insertion section being provided with an expandable balloon, the outer side of the balloon wall being surrounded by multiple outlets for drug flow, the inner lumen of the gastric tube body also being provided with an auxiliary insertion tube for inserting the end of the insertion section into the stomach, the end of the auxiliary insertion tube being provided with a pH detection head, the pH detection head being a spherical structure, and the auxiliary insertion tube and the gastric tube body being a clearance fit.

[0005] Preferably, the inlet end of the external segment is connected to a connecting tube, and the end of the connecting tube is symmetrically connected to an elastic insert.

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Example 1. This utility model provides the following: Figure 1-2 The gastric tube assembly shown includes a gastric tube body 1, which includes an external segment and an insertion segment. The insertion segment has an expansion balloon 8 at its end. The outer side of the balloon wall of the expansion balloon 8 is surrounded by multiple outlets 801 for drug flow. The inner lumen of the gastric tube body 1 is also provided with an auxiliary insertion tube 6 for inserting the end of the insertion segment into the stomach. The end of the auxiliary insertion tube 6 is provided with a pH detection head 602, which has a spherical structure. The auxiliary insertion tube 6 and the gastric tube body 1 are fitted with a gap.

[0021] Specifically, the gastric tube body 1 is made of polyurethane, and the expansion balloon 8 is made of silicone. It is fixed to the polyurethane gastric tube body 1 by heat fusion. When the expansion balloon 8 is pushed by the injected drug, it expands and the drug flows out in a dispersed manner through multiple outlets 801, thereby reducing the irritation to the stomach wall caused by the concentrated flow of the drug.

[0022] The inflatable balloon 8 has a structure similar to a balloon. After being filled with liquid, it expands and ejects the liquid. Because the balloon structure is flexible, it needs to be used in conjunction with an auxiliary intubation tube 6. The auxiliary intubation tube 6 can be a disposable plastic or steel wire flexible tube. During insertion, since the pH detection head 602 of the auxiliary intubation tube 6 is located inside the liquid outlet 801, gastric acid will seep into the inside of the inflatable balloon 8 after it enters the stomach. When the nurse is intubating the patient, she can withdraw the auxiliary intubation tube 6 when she estimates that the intubation is in place. If the pH detection head 602 changes color and shows an acidic result, the intubation is in place. If it does not change color, it needs to be inserted again.

[0023] Example 2: See Figure 3-5 The inlet end of the external segment is connected to a connecting tube 3, and the end of the connecting tube 3 is symmetrically connected to an elastic insert 301. The end of the elastic insert 301 is connected to an injection head 2. The side of the end of the elastic insert 301 is provided with an oblique protrusion for locking the injection head 2, and the side of the injection head 2 is provided with a pressing element for unlocking the elastic insert 301.

[0024] It should be noted that the connecting tube 3 is made of polypropylene and is glued to the inner wall of the liquid inlet end of the gastric tube body 1. The inner wall of the insertion end of the injection head 2 is provided with a locking groove 201 for oblique protrusion engagement, and the side of the locking groove 201 is provided with a movable groove 202 for pressing and moving the pressing component.

[0025] Specifically, the pressing component includes a handle 4 symmetrically arranged on the outside of the injection head 2. A push plate 5 is inserted and connected to the side of the handle 4. One end of the push plate 5 is inserted and connected to the inside of the movable groove 202. The push plate 5 is used to squeeze the oblique protrusion. An elastic block 501 is provided on the inner wall of the movable groove 202. The elastic block 501 is used to push the push plate 5 to reset.

[0026] It should be noted that the handle 4 and the injection head 2 are fixed by integral injection molding. The side of the handle 4 is provided with a moving groove for the push plate 5 to pass through. The moving groove is connected to the movable groove 202, so that the push plate 5 can move in the movable groove 202. The push plate 5 is made of polypropylene, which is tough. Due to the restriction of the push plate 5 by the movable groove 202, the push plate 5 is not easy to fall off from the moving groove.

[0027] Specifically, the elastic block 501 is made of rubber and is glued to the inner wall of the movable groove 202. When the elastic block 501 is squeezed, it can push the push plate 5 to reset, so as to avoid the movement of the push plate 5 from affecting the locking of the oblique protrusion and the inner wall of the locking groove 201.

[0028] Specifically, one end of the auxiliary intubation tube 6 is sequentially inserted and connected to the inner lumen of the injection head 2, the connecting tube 3, and the gastric tube body 1. The other end of the auxiliary intubation tube 6, located at the inlet end of the injection head 2, is provided with a guide head 601. The guide head 601 is used for the withdrawal of the auxiliary intubation tube 6. The inlet end of the injection head 2 is provided with a cap 7. A traction rope 701 for limiting the cap 7 is provided on the side of the injection head 2.

[0029] It should be noted that the insertion point of the auxiliary cannula 6 and the guide head 601 is fixed with adhesive. The auxiliary cannula 6 is used to guide the insertion of the gastric tube body 1 into the patient's body, so as to avoid the difficulty of inserting the soft gastric tube body 1.

[0030] In actual use, an expansion balloon 8 is provided at the end of the insertion section of the gastric tube body 1. The surface of the expansion balloon 8 is provided with multiple liquid outlets 801. When the medicine is injected from the injection head 2, the injection pressure pushes the expansion balloon 8 to expand, and the medicine flows out from the multiple liquid outlets 801. This design can increase the injection area of ​​the liquid, disperse the pressure, and avoid the impact of concentrated liquid outflow. At the same time, the expansion balloon 8 can isolate the insertion section of the gastric tube body 1 from the gastric mucosa, avoiding the phenomenon of local pressure concentration caused by direct contact between the end of the insertion section of the gastric tube body 1 and the gastric mucosa.

[0031] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
