Description

Technical Field

[0001] The utility model relates to the technical field of medical gastric tube fixation, in particular to a visual gastric tube fixer. Background Art

[0002] A gastric tube is a tube inserted from the nasal cavity that can extend to the stomach. It is often used in medical operations such as gastrointestinal decompression and enteral nutrition. For example, some patients cannot eat normally after surgery, and liquid food can be injected through the gastric tube to supplement the patient's nutrition. For patients with intestinal obstruction, inserting a gastric tube can lead gastric juice out of the body to prevent gastric juice from draining downward. Some patients need to have a gastric tube in place during surgery for gastrointestinal drainage and decompression, etc. However, the placement of a gastric tube requires fixing the tube. The current common clinical practice is to use medical adhesive patches to directly stick the gastric tube to the nose wing and nose tip, but it is easy to move or fall off, and it needs to be fixed repeatedly, causing allergies or damage to the nose skin, causing physical discomfort to the patient. Therefore, it is necessary to provide a visual gastric tube fixator to solve the above technical problems. Utility Model Content

[0003] In view of the above-mentioned shortcomings of the prior art, the purpose of the utility model is to provide a visual gastric tube fixer, which has the advantages of convenient fixing operation, dispersed force, less contact surface with the nose and easy observation.

[0005] A visual gastric tube fixer comprises a nose mold similar in shape to a nose and a gastric tube detachably connected to the nose mold, the nose mold comprising: a frame for buckling on the bridge of the nose and the back of the nose, a transparent window arranged below the frame for observing the nose tip and the wings of the nose, patches arranged on both sides of the transparent window for attaching to both sides of the wings of the nose, a bearing plate located at the bottom of the nose mold (1) for buckling on the bottom of the nose and fixing the gastric tube, the bearing plate being provided with a through hole for the gastric tube to pass through.

[0006] To implement the above technical solution, when in use, first measure the length of the gastric tube to be inserted, then pass the gastric tube through the through hole of the carrier plate, adjust it to the corresponding scale position and fix it, which serves to prompt the insertion depth, then intubate the patient with the gastric tube, fine-tune the position of the nose mold to adapt it to the position of the nose, then tear off the release paper on the patch, snap the nose mold on the patient's nose to fix it, because the frame is snapped on the bridge of the nose and the back of the nose, it has a certain fixing effect on the nose mold, and the patch assists in fixing the nose mold to the side of the nose wing. The force point of the gastric tube is on the carrier plate, and the force is dispersed to the frame and the patch, avoiding the traditional practice of relying solely on the nose wing adhesive to fix the gastric tube, which damages the mucosa around the nostrils.

[0007] As a preferred solution of the utility model, the support plate is a single-sided semi-enclosed structure, which implements the above technical solution and avoids affecting the patient's breathing.

[0008] As a preferred solution of the utility model, a fixing ring is provided in the through hole, and a plurality of raised blocks are provided on the inner wall of the fixing ring. When the gastric tube passes through the fixing ring, the surface of the gastric tube fits with the surface of the raised blocks. The raised blocks are elastic colloids. To implement the above technical solution, the plurality of raised blocks in the fixing ring generate a squeezing force on the surface of the gastric tube, thereby strengthening the fixation of the gastric tube, preventing the gastric tube from sliding in the fixing ring, and making the fixation of the gastric tube more stable to a certain extent.

[0009] As a preferred solution of the utility model, the dressing is a multi-layer structure, which includes a 3M transparent dressing layer, a polyurethane film layer, a hydrogel layer, and a release paper from the outside to the inside.

Through the transparent window, medical staff can observe the skin around the nostrils and nose wings from the outside without removing the nose mold, and observe whether the mucosa near the nasal tube is damaged. , allergies and the like, patches 14 for attaching to both sides of the nose wings are arranged on both sides of the transparent window 12, and a supporting plate 13 for buckling under the nose bottom and fixing the gastric tube 2 is arranged at the bottom of the nose mold 1, and a through hole 15 for the gastric tube 2 to pass through is provided on the supporting plate 13, and the gastric tube is fixedly connected to the nose mold through the through hole, and the supporting plate 13 is a unilateral semi-closed structure, that is, the supporting plate under one nostril has a through hole, and the other nostril is empty, and is closely connected to the transparent window and the patch on this side through an arc-shaped narrow edge, which effectively avoids the influence of the fully enclosed supporting plate on the patient's breathing. When using, first measure the length of the gastric tube to be inserted, then pass the gastric tube through the through hole of the carrier plate, adjust it to the corresponding scale position and fix it, which serves to prompt the insertion depth, and then intubate the patient with the gastric tube. After the intubation is completed, fine-tune the position of the nose mold to adapt it to the position of the nose, and then tear off the release paper on the patch, snap the nose mold on the patient's nose to fix it. Since the frame is snapped on the bridge of the nose and the back of the nose, it has a certain fixing effect on the nose mold. The patch assists in fixing the nose mold to the side of the nose wing. The force point of the gastric tube is on the carrier plate, and the force is dispersed to the frame and the patch, reducing the force of the gastric tube on the nostrils, and avoiding the traditional practice of only relying on the nose wing glue to fix the gastric tube, which damages the mucosa around the nostrils.

[0028] In order to strengthen the fixation of the gastric tube and increase the stability of the fixation, a fixing ring 3 is arranged in the through hole 15, and a plurality of raised blocks 31 made of elastic colloid are arranged on the inner wall of the fixing ring 3. When the gastric tube 2 passes through the fixing ring 3, the surface of the gastric tube 2 fits with the surface of the raised blocks 31, and the plurality of raised blocks in the fixing ring generate an extrusion force on the surface of the gastric tube, thereby strengthening the fixation of the gastric tube and preventing the gastric tube from sliding in the fixing ring, thereby making the fixation of the gastric tube more stable to a certain extent.

[0029] In order to reduce the phenomenon of skin allergies caused by adhesive tape, the dressing 14 of this embodiment adopts a multi-layer structure, which includes a 3M transparent dressing layer, a polyurethane film layer, a hydrogel layer, and a release paper from the outside to the inside. After tearing off the release paper, the hydrogel layer is tightly attached to the patient's skin, effectively avoiding the use of ordinary medical adhesive tape to cause skin allergies in patients, improving patient comfort, and facilitating the peeling and disassembly of the gastric tube fixator.

[0030] In order to further enhance the fixing effect of the frame, a patch 111 is provided on the inner outer edge of the frame 11. The patch 111 is a hydrogel layer. At the same time, in order to increase the air permeability of the frame and improve the comfort of using the gastric tube fixer, a ventilation hole 112 is provided on the frame 11.
