Description

Technical Field

[0001] The invention belongs to the technical field of gastric tube fixation, and particularly relates to an oral gastric tube fixation device. Background Art

[0002] For patients in a coma, for detoxification, and for patients with dysphagia and refusal to eat caused by upper digestive tract tumors, gastric tubes need to be inserted; gastric tubes are generally made of polyurethane or silica gel materials, with different specifications in terms of thickness, length, and diameter, and the gastric tubes are respectively inserted through the mouth and through the nasal cavity. Inserting through the nasal cavity means inserting a catheter through the nasal cavity into the stomach, which is applicable to patients who cannot eat through the mouth, and is used to supply food and drugs through a nasogastric tube, and for indwelling gastric tube gastrointestinal decompression, etc.; when encountering patients with contraindications to indwelling a gastric tube through the nasal cavity such as basilar skull fracture complicated with cerebrospinal fluid leakage, nasal trauma, nasal septum deviation, nasopharyngeal carcinoma, and massive nasal bleeding, so for the above-mentioned patients, it is necessary to insert a gastric tube through the oral cavity.

[0003] The existing common method for inserting a gastric tube through the oral cavity is to select a No. 12 - 14 silica gel gastric tube, measure the length as the distance from the anterior hairline of the forehead to the xiphoid process, and then add 8 - 10 cm as the insertion length. The front end of the gastric tube is lubricated with paraffin oil, and finally fixed with adhesive tape; for inserting a gastric tube through the oral cavity, in the later care, patients often involuntarily chew the gastric tube. If in order to prevent chewing or flattening of the gastric tube, adding a bite block makes oral care inconvenient and it is not easy to thoroughly clean the oral cavity. Secondly, when the nurse removes the endotracheal tube, the bite block and the endotracheal tube need to be separated before removing the endotracheal tube, otherwise it is easy to pull out the gastric tube passing through the bite block. There are also disadvantages for fixing with adhesive tape. Due to reasons such as sweating and facial oiliness of the patient, the adhesion between the adhesive tape and the skin is not firm, which easily causes the gastric tube to slip off. Some patients are prone to allergies, leading to serious complications. As the patient turns over or moves, the fixing effect is not ideal. After several times of fixing with adhesive tape on the face, the adhesive tape marks are difficult to clean, which is neither beautiful nor comfortable for the patient. Frequent replacement of the adhesive tape is likely to cause skin damage to the patient, increasing the possibility of infection, and at the same time increasing the workload of the nurse. Summary of the Invention

[0004] In order to solve the problems that when inserting a gastric tube through the oral cavity, patients involuntarily chew the gastric tube, resulting in gastric tube blockage, and the disadvantages of fixing with adhesive tape, etc., the invention provides an oral gastric tube fixation device.

[0005] In order to achieve the above object, the technical scheme adopted by the invention is as follows:

[0006] An oral gastric tube fixation device, the fixation device includes an arc-shaped fixing tube body, the inner wall of the arc-shaped fixing tube body is provided with a plurality of supporting convex portions, an opening is provided on the axial tube wall of the arc-shaped fixing tube body, a clamping groove is provided at the end of one side tube wall, a clamping member is provided at the end of the other side tube wall, an oral pad is sleeved at the front end of the arc-shaped fixing tube body, restraint ropes are installed on both sides of the oral pad, and the tightness of the restraint ropes is adjusted through a tightness adjustment buckle.

[0007] Further, the arc-shaped fixing tube body is made of polyurethane or silica gel material.

[0008] Further, the supporting convex portions are arranged around the inner wall of the arc-shaped fixing tube body, and the supporting convex portions are arranged axially or radially.

[0009] Further, ear grooves are provided at both ends of the mouth pad, and the restraint ropes pass through the ear grooves and cooperate with the tension adjusting buckle, and are hung on the ears through the restraint ropes.

[0010] Further, the length of the arc-shaped fixing tube body is 6-9 cm.

[0011] Further, the inner diameter of the arc-shaped fixing tube body is 10-15 mm.

[0012] Compared with the prior art, the above technical solution can obtain the following beneficial effects:

[0013] In the present invention, the inner wall of the fixing device is provided with supporting convex portions. When the patient involuntarily chews the arc-shaped fixing tube body, under the buffering and protection of the supporting convex portions, the gastric tube will not be bitten or blocked. The supporting convex portions will play a supporting role to prevent the gastric tube from closing and affecting the flow of food into the stomach. At the same time, the supporting convex portions are distributed on the entire inner wall of the arc-shaped fixing tube body, which also increases the overall toughness of the arc-shaped fixing tube body.

[0014] The tension adjusting buckle of the present invention controls the tightness of the restraint ropes. The tension adjusting buckle is simple to use and prevents squeezing the patient's face. Compared with the existing adhesive tape, the patient will not be allergic and the skin will not be damaged. The cooperation of the restraint ropes and the tension adjusting buckle can effectively fix the fixing device and prevent the fixing device from falling off. Secondly, the mouth pad is connected to the arc-shaped fixing tube body. On the one hand, the mouth pad can effectively clamp the fixing tube body, and on the other hand, the ear grooves on both sides are connected to the restraint ropes.

[0022] The present invention will be further described below with reference to the accompanying drawings:

[0023] Embodiment 1 Figure 1 and 2 As shown, an oral gastric tube fixing device, the fixing device includes an arc-shaped fixed tube body 1, the arc-shaped fixed tube body 1 is made of polyurethane or silica gel material, and several support protrusions 6 are arranged on the inner wall of the arc-shaped fixed tube body 1. In this embodiment, six support protrusions 6 are evenly axially arranged on the inner wall of the tube body. An opening is formed in the axial tube wall of the arc-shaped fixed tube body 1. A card slot 5 is arranged at one end of the tube wall at the opening, and a fastening piece 7 is arranged at the other end of the tube wall. The fastening piece 7 is in the shape of a triangular chuck, and the triangular chuck can be effectively stuck in the card slot 5 to realize the closed state of the tube wall. A mouth pad 4 is sleeved at the front end of the arc-shaped fixed tube body 1, and restraining ropes 2 are installed on both sides of the mouth pad 4. The restraining ropes 2 are adjusted in tightness through the tightening adjustment buckle 3; the length of the arc-shaped fixed tube body 1 is 8 cm, and the inner diameter is 10 mm.

[0024] During the specific use process, open the opening of the arc-shaped fixed tube body 1. For example Figure 4 and 5 As shown, the gastric tube is placed into the arc-shaped fixed tube body 1, and then the arc-shaped fixed tube body 1 is closed. Specifically, when the two side walls at the opening are butted, the triangular head of the fastening piece 7 will enter the card slot 5. In this embodiment, two groups of card slots and fastening pieces are used to realize effective locking ( Figure 3 As shown), so that the entire tube body wraps and fixes the gastric tube. A mouth pad 4 is sleeved at the front end of the tube body, and restraining ropes 2 are installed on both sides of the mouth pad 4. The restraining ropes are hung on the ears, and the tightness of the restraining ropes is adjusted through the tightening adjustment buckle 3 to ensure the comfort of the patient during use.

[0025] After using for a period of time, when the arc-shaped fixed tube body 1 needs to be replaced, since the arc-shaped fixed tube body 1 is made of polyurethane or silica gel material and has a certain flexibility, pinch the opening with your hand and press down, then the fastening piece 7 can be disengaged from the card slot 5 to open the opening and replace the new arc-shaped fixed tube body 1.

[0026] In the above embodiment, during docking, in order to better enable the fastening piece to smoothly enter the card slot 5, the area near the card slot 5 is designed with a gradual slope to adaptively cooperate with the fastening piece 7 with a triangular head.

[0027] All of the above are the preferred implementation modes of the present invention.
