Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a nasogastric feeding tube. Background Technology

[0002] A nasogastric tube is a tube inserted into the stomach through the nasal cavity. Clinically, it is generally called a nasogastric tube, or simply a gastric tube. It is mainly used for nasogastric feeding, where nutrient-rich liquid foods, nutritional solutions, water, and medications are delivered into the stomach through the tube to ensure the patient receives sufficient protein, calories, and other nutrients and medications. Nasogastric tubes are usually made of soft, non-toxic medical materials, such as silicone and polyurethane, to minimize irritation to human tissues. The tube is typically a long, thin tube with multiple side holes at one end for draining or infusing fluids into the stomach, and a connector at the other end for connecting to syringes, infusion sets, etc., facilitating the administration of food, medications, or the extraction of gastric fluid. The tube is also marked with graduations to help healthcare workers determine the insertion depth.

[0003] The existing nasogastric tubes are ordinary silicone tubes without a one-way structure, which can cause gastric juice to reflux and affect the patient's safety. Utility Model Content

[0004] The purpose of this invention is to overcome the existing defects and provide a nasogastric tube with a one-way structure that can prevent gastric juice reflux and protect the patient's safety.

[0005] The technical solution to achieve the above objective is as follows: a nasogastric tube includes a tube body, an installation sleeve connected to the end of the tube body, a first annular magnetic ring installed inside the installation sleeve, a first protective sleeve tightly attached to the installation sleeve, a second annular magnetic ring and a teardrop-shaped guide block installed inside the first protective sleeve, the second annular magnetic ring connected to the outer wall of the teardrop-shaped guide block, the second annular magnetic ring and the first annular magnetic ring attracting each other, one end of a plurality of elastic fixing bands evenly connected to the first protective sleeve, the other end of each elastic fixing band connected to the outer wall of the tube body, the middle part of each elastic fixing band passing through a limiting sleeve connected to the outer wall of the tube body, and a fastening component installed at the front end of the tube body.

[0006] Preferably, the fastening assembly includes an air bladder, a first trachea, a second trachea, and a one-way valve. The front end of the gastric tube body is connected to the air bladder, the air bladder is connected to one end of the first trachea, the other end of the first trachea is connected to the second trachea, and the one-way valve is installed inside the second trachea.

[0007] Preferably, the inner wall of the limiting sleeve is evenly provided with multiple sliding grooves, and each of the elastic fixing bands passes through the corresponding sliding groove.

[0008] Preferably, the top end of the gastric tube body is provided with an external thread, and the top end of the gastric tube body is threadedly connected with a second protective sleeve.

[0009] Preferably, a magnetic base is provided on the side wall of the second protective sleeve, the magnetic base is in close contact with a rectangular magnetic block, and the rectangular magnetic block is connected to the outer side wall of the second air tube.

[0010] Preferably, the second air tube can be connected to an external inflation tube and inflation device.

[0011] The beneficial effects of this utility model are: through the combined action of magnetic attraction and elasticity, the second annular magnetic ring is attracted to the first annular magnetic ring. At this time, the mounting sleeve and the first protective sleeve are tightly attached to each other, which can prevent gastric juice reflux and protect the patient's safety.

[0012] When it is necessary to secure the device, connect the second trachea to the inflation tube and inflation device. Gas enters the air bladder through the second and first tracheas, at which point the air bladder inflates and fills the patient's nasal cavity. This replaces the use of tape for fixation, making the fixation more secure. Attached Figure Description

Furthermore, the terms "first," "second," and "third" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0021] The present invention will be further described below with reference to the accompanying drawings.

[0022] like Figure 1-6 As shown, a nasogastric tube includes a tube body 1, an installation sleeve 2, a first annular magnetic ring 3, a first protective sleeve 6, a second annular magnetic ring 5, a teardrop-shaped guide block 4, multiple elastic fixing straps 7, a limiting sleeve 8, and a fastening assembly.

[0023] Specifically, the end of the gastric tube body 1 is connected to an installation sleeve 2, and a first annular magnetic ring 3 is installed inside the installation sleeve 2. The installation sleeve 2 is tightly attached to a first protective sleeve 6, and a second annular magnetic ring 5 and a teardrop-shaped guide block 4 are installed inside the first protective sleeve 6. The second annular magnetic ring 5 is connected to the outer wall of the teardrop-shaped guide block 4. The teardrop-shaped guide block 4 can change the center of gravity of the second annular magnetic ring 5, making it easier for the second annular magnetic ring 5 to be attracted by the first annular magnetic ring 3. The second annular magnetic ring 5 and the first annular magnetic ring 3 attract each other. One end of a plurality of elastic fixing bands 7 are evenly connected to the first protective sleeve 6. The other end of each elastic fixing band 7 is connected to the outer wall of the gastric tube body 1. The middle part of each elastic fixing band 7 passes through a limiting sleeve 8, which is connected to the outer wall of the gastric tube body 1. A fastening component is installed at the front end of the gastric tube body 1.

[0024] Specifically, the fastening assembly includes an airbag 9, a first trachea 10, a second trachea 11, and a one-way valve 12. The front end of the gastric tube body 1 is connected to the airbag 9, the airbag 9 is connected to one end of the first trachea 10, the other end of the first trachea 10 is connected to the second trachea 11, and the one-way valve 12 is installed inside the second trachea 11.

[0025] Specifically, the inner wall of the limiting sleeve 8 is evenly provided with multiple sliding grooves 15, and each elastic fixing band 7 passes through the corresponding sliding groove 15.

[0026] Specifically, the top of the gastric tube body 1 is provided with an external thread, and the top of the gastric tube body 1 is threadedly connected to a second protective sleeve 13. The second protective sleeve 13 can protect the port of the gastric tube body 1 when this device is not used. A magnetic seat 14 is provided on the side wall of the second protective sleeve 13. The magnetic seat 14 is closely attached to a rectangular magnetic block 16. The rectangular magnetic block 16 is connected to the outer side wall of the second trachea 11. The magnetic structure can fix the second trachea 11 to the second protective sleeve 13 to prevent the second trachea 11 from shaking randomly. The second trachea 11 can be connected to an external inflation tube and inflation equipment.

[0027] Working principle: When the nutrient solution enters the gastric tube body 1, the pressure will push the second annular magnetic ring 5 and the teardrop-shaped guide block 4 downward. At this time, the pressure of the nutrient solution is greater than the sum of the magnetic attraction (the attraction between the second annular magnetic ring 5 and the first annular magnetic ring 3) and the elastic force (multiple elastic fixing bands 7). In this way, the nutrient solution can be discharged from the gastric tube body 1. When there is no pressure from the nutrient solution, under the combined action of the magnetic attraction and the elastic force, the second annular magnetic ring 5 is attracted to the first annular magnetic ring 3. At this time, the mounting sleeve 2 and the first protective sleeve 6 are tightly attached to each other, which can prevent gastric juice reflux and protect the patient's safety.

[0028] When it is necessary to fix the device, connect the second trachea 11 to the external inflation tube and inflation device. The gas enters the air bag 9 through the second trachea 11 and the first trachea 10. At this time, the air bag 9 inflates and fills the patient's nasal cavity, which replaces the tape fixation and makes the fixation tighter.

[0029] The above embodiments are only used to illustrate the technical solutions of this utility model, and are not intended to limit it. Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
