Description

Technical Field

[0001] This utility model relates to the field of medical device technology, specifically to a gastric tube fixation device to prevent pressure injury. Background Technology

[0002] Nasogastric tubes, also known as nasogastric feeding tubes, are mostly flexible, slender tubes, about 120cm in length. In clinical medicine, when patients are in a coma, have oral or cervical diseases, severe burns, terminal cancer, or have difficulty swallowing due to surgery and are unable to eat through their mouths, nasogastric tubes can be inserted to deliver food to the patient's stomach via nasogastric tube, providing the patient with necessary food and nutrition.

[0003] Currently, when children use nasogastric tubes, they are often secured with tape. However, due to the delicate skin of children and the varying sizes of their nostrils, traditional methods of securing nasogastric tubes often present many inconveniences and potential risks.

[0004] In summary, there is an urgent need to design a pressure-resistant gastric tube fixation device that overcomes the aforementioned technical problems. Utility Model Content

[0005] In view of the problems mentioned in the background art, the purpose of this utility model is to provide a pressure-resistant gastric tube fixation device to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, this utility model mainly provides the following technical solutions:

[0007] A pressure-resistant gastric tube fixation device includes a gastric tube cannula and a gastric tube fixation assembly; wherein:

[0008] The gastric tube cannula includes a first cannula and a second cannula, which are integrally formed; the first cannula is placed inside the nostril and the second cannula is placed outside the nostril.

[0009] The gastric tube fixation assembly is movably connected to the top end of the second cannula.

[0010] Furthermore, the cannula is semi-circular in shape and its inner diameter is larger than the outer diameter of the gastric tube;

[0011] The cannula comprises, from the inside out, an adhesive layer, a silicone layer, an airbag layer, and a skin-adhesive layer.

[0012] Furthermore, the second cannula is annular with an opening and covers the outer wall of the gastric tube;

[0013] The inner diameter of the second cannula is larger than the outer diameter of the gastric tube, and the outer diameter of the second cannula is larger than the outer diameter of the first cannula.

[0014] Furthermore, the gastric tube fixation assembly includes a nasal patch and adhesive patch one and adhesive patch two disposed at the tail end of the nasal patch.

[0015] The nose-shaped patch has a connecting part at its end, which is connected to the second sleeve by adhesive.

[0016] Furthermore, the nose patch is a medical breathable adhesive patch with release paper on its inner surface;

[0017] The adhesive tape one and adhesive tape two are strip-shaped adhesive tapes with release paper on the inner surface.

[0018] Compared with the prior art, the beneficial effects of this utility model are mainly reflected in:

[0019] This utility model discloses a pressure-resistant gastric tube fixation device, wherein the gastric tube sleeve includes a first sleeve and a second sleeve. This device can not only effectively fix the gastric tube and reduce the risk of nasal pressure and skin damage, but also constrain and fix the main body of the gastric tube, further improving the stability of the gastric tube and preventing the problem of tube dislodgement.

[0020] The present invention relates to a pressure-resistant gastric tube fixation device, wherein the sleeve is placed inside the child's nostril and is designed in a semi-circular arc shape, which can fit tightly to the upper part of the child's nostril while providing sufficient decompression space.

[0032] To further illustrate the technical means and effects adopted by this utility model to achieve its intended purpose, the following detailed description, in conjunction with the accompanying drawings and preferred embodiments, details the specific implementation method, structure, features, and effects of the anti-pressure injury gastric tube fixation device proposed according to this utility model.

[0033] Example 1

[0034] Please see Figures 1-5 In this embodiment, a pressure-resistant gastric tube fixation device is provided, comprising a gastric tube sheath 1 and a gastric tube fixation assembly 2; wherein:

[0035] The gastric tube cannula 1 includes an integrally formed cannula 11 and cannula 2 12; cannula 11 is placed inside the nostril and cannula 2 12 is placed outside the nostril; cannula 11 is used to insert into the inside of the nostril, and its material is soft and its surface is smooth to reduce irritation and damage to the nasal mucosa; cannula 2 12 is located outside the nostril and is integrally connected to one end of cannula 11 to facilitate further fixation of the gastric tube 3;

[0036] The gastric tube fixing component 2 is movably connected to the top end of the second cannula 12; it is used to fix the gastric tube on the cannula to prevent it from sliding or falling off.

[0037] This invention relates to a pressure-resistant gastric tube fixation device, which aims to solve the problems of nasal compression and skin damage caused by long-term wearing of gastric tubes in children, while ensuring stable fixation of the gastric tube. It has a simple structure, is easy to operate, safe and reliable, and has broad clinical application prospects.

[0038] Example 2

[0039] Based on Example 1, the cannula 11 is semi-circular and its inner diameter is larger than the outer diameter of the gastric tube; ensuring that the gastric tube can pass through easily and is not easy to slip; at the same time, the cannula 11 is semi-circular to adapt to the physiological structure of the nostrils.

[0040] The sleeve 11 comprises, from the inside out, an adhesive layer 111, a silicone layer 112, an airbag layer 113, and a skin-adhesive layer 114.

[0041] Specifically, the adhesive layer 111 is preferably of type 22 adhesive, which is used to fix the cannula 11 to the outer wall of the gastric tube to ensure stability; the silicone layer 112 is preferably soft and elastic flexible silicone.

[0049] The cannula 11 is fixed inside the nostril by the adhesive layer 111, while the silicone layer 112 and the airbag layer 113 provide soft support and a comfortable wearing experience.

[0050] After connecting cannula 2 12 with cannula 11, a complete ring structure is formed, which wraps the gastric tube inside; cannula 2 12 and cannula 11 are connected as one piece, and the connection between the two is more stable, effectively preventing the gastric tube from slipping or falling off.

[0051] Example 4

[0052] Based on Embodiment 1, the gastric tube fixing assembly 2 includes a nose-shaped patch 21 and adhesive patch 22 and adhesive patch 23 disposed at the tail end of the nose-shaped patch 21; the adhesive patch 22 and adhesive patch 23 are strip-shaped adhesive patches with release paper on the inner surface, providing additional fixing force to prevent the gastric tube from moving.

[0053] The nose-shaped patch 21 has a connecting part 24 at its end, which is connected to the sleeve 12 by adhesive.

[0054] The nose-shaped patch 21 is designed to fit the shape of the nose, and the inner surface is covered with release paper and is a breathable medical adhesive. The end of the nose-shaped patch 21 is provided with a connecting part 24, which is connected to the top of the second sleeve 12 by adhesive bonding to ensure the overall stability of the gastric tube fixation device.

[0055] Furthermore, the nose patch 21 is a medical breathable adhesive patch with release paper on its inner surface; the first adhesive patch 22 and the second adhesive patch 23 are strip-shaped adhesive patches with release paper on their inner surfaces.

[0056] The present invention has been further described above with reference to the embodiments, but the present invention is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present invention.
