Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to an improved nasogastric tube device. Background Art

[0002] A nasogastric tube is a flexible medical tube inserted through the nose, passing through the nasal cavity and esophagus before entering the stomach. It is primarily used to assist patients who are unable to eat orally due to coma, oral diseases, insufficient food intake, coma, paralysis, stroke, cerebrovascular disease, paralysis, choking, dysphagia, esophageal disease, and other conditions that restrict movement or prevent normal feeding. Fluids must be delivered to the stomach through the nasogastric tube in a timely, quantitative, safe, and reliable manner, ensuring that the patient receives the appropriate nutrition or medication.

[0003] In the prior art, after the general nasogastric tube is inserted into the patient's stomach and the intubation is completed, a section of the joint is left exposed and hung outside the patient's nasal cavity for the convenience of subsequent feeding, and the tube body is directly placed on the outside of the face. Currently, most of the two-stage nasogastric tubes used are equipped with a detachable or transfer structure at the exit of the nasal cavity of the human body. However, the connection structure of the existing nasogastric tube is complex, and the operation is cumbersome, which can easily cause discomfort to the patient or make it impossible to quickly achieve the effect of detachment and transfer. At the same time, after the transfer of this type of nasogastric tube is completed, the nasogastric tube is directly adhered to the patient's nose through a nose patch. Such operation makes the nasogastric tube less stable and easy to pull and slip. When the nasogastric tube slips unexpectedly, it will affect the patient's food and water intake, causing nutritional imbalance. Utility Model Content

[0004] The purpose of the utility model is to provide an improved nasogastric tube device to solve the problem that the existing nasogastric tube connection has a complex structure, poor stability, and is easily pulled and slipped, resulting in unexpected slippage, affecting the patient's food and water intake and causing nutritional imbalance.

[0024] like Figure 1-6The improved nasogastric tube device shown includes a nasogastric tube body 1, a first adjustment and fixing assembly 2 disposed on one end of the nasogastric tube body 1, a mounting ring thread groove 3 disposed within the connecting end of the nasogastric tube body 1, a mounting threaded sleeve 4 disposed within the mounting ring thread groove 3, a through hole 5 disposed at one end of the mounting threaded sleeve 4, a positioning pin 6 disposed within the through hole 5, and the positioning pin 6 extends through a side wall of the nasogastric tube body 1 and a side wall of the mounting threaded sleeve 4, respectively. An auxiliary connecting tube body 7 is disposed on the end of the mounting threaded sleeve 4 away from the nasogastric tube body 1, a second adjustment and fixing assembly 8 disposed on the auxiliary connecting tube body 7, an auxiliary branch tube 9 disposed on the auxiliary connecting tube body 7, and a sealing plug disposed on the auxiliary branch tube 9. It should be noted that the threaded hole disposed in the auxiliary branch tube 9 allows for threaded connection with the auxiliary tube, and can also be used with a syringe for direct gavage and injection.

[0025] Specifically, the first adjustment and fixing assembly 2 and the second adjustment and fixing assembly 8 each include a sleeve 10, which is sleeved over the nasogastric tube body 1 and the auxiliary connecting tube body 7. A threaded hole is provided on the sleeve 10, and a locking bolt 11 is provided in the threaded hole. An anti-slip arc piece 12 is provided at the bottom end of the locking bolt 11. The anti-slip arc piece 12 is provided between the sleeve 10 and the nasogastric tube body 1 and the auxiliary connecting tube body 7. An anti-slip semicircular gasket 13 is provided on the opposite side of the anti-slip arc piece 12. The anti-slip semicircular gasket 13 is provided on the inner wall of the sleeve 10, and an adhesive piece 14 is provided at one end of the sleeve 10. It should be noted that the gap between the anti-slip arc piece 12 and the anti-slip semicircular gasket 13 is larger than the gap between the nasogastric tube body 1 and the auxiliary connecting tube body 7, which facilitates the free sliding of the sleeve 10 to the desired position for positioning.

[0026] Specifically, a tearable protective film is provided on the adhesive sheet 14, and a plurality of ventilation holes are provided on the adhesive sheet 14. The adhesive sheet 14 is provided in a plurality of sheets. It should be noted that when the cannula 10 is moved into place, the protective film is torn off and the adhesive sheet 14 is adhered to the patient, while the ventilation holes ensure its comfort in use.

[0027] Specifically, a soft pad is provided on the outer surface of the positioning pin 6 to fit into the through hole 5, and a hard tube is provided at the connection between the nasogastric tube body 1 and the auxiliary connecting tube body 7. It should be noted that the soft pad provided on the positioning pin 6 to fit into the through hole 5 will prevent it from falling out easily after being inserted into the through hole 5, thereby affecting the stability of the connection, and at the same time achieve the effect of secondary connection and fixation.

[0028] Specifically, the anti-slip arc piece 12 and the anti-slip semicircular gasket 13 are both provided with an anti-slip layer at their respective ends adjacent to each other. The anti-slip arc piece 12 is positioned within the mounting holes on the inner wall of the sleeve 10 via mounting guide posts. It should be noted that the anti-slip arc piece 12 can be installed and removed from the sleeve 10 as needed, and after installation, it can be raised and lowered using the mounting guide posts in conjunction with the mounting holes, and finally tightened by the locking bolts 11.

[0029] The working principle of this specific embodiment is: first, insert the nasogastric tube body 1 into the patient's body. When the nasogastric tube body 1 is in place, the first adjustment and fixing component 2 is installed on the nasogastric tube body 1, and the second adjustment and fixing component 8 is installed on the auxiliary connecting tube body 7. Then, the nasogastric tube body 1 is connected to the auxiliary connecting tube body 7 by using the mounting threaded ring sleeve 4 and the mounting ring thread groove 3. After the connection is completed, the positioning pin 6 is inserted into the through hole 5 to achieve the effect of secondary fixation. Then, the sleeve 10 is moved to the required fixed position, and the locking bolt 11 is rotated and pressed down to make the anti-slip arc piece 12 drop and cooperate with the anti-slip semicircular gasket 13 to clamp the nasogastric tube body 1 and the auxiliary connecting tube body 7. The protective film is torn off and the adhesive piece 14 is adhered and fixed to the patient's nose and ears to achieve the effect of fixing the nasogastric tube body 1 and the auxiliary connecting tube body 7. At the same time, the auxiliary branch tube 9 can be used for auxiliary feeding and injection as needed.

[0030] The present invention is not limited to the aforementioned specific embodiments, but extends to any new features or any new combination disclosed in this specification, as well as any new method or process steps or any new combination disclosed.
