Technical Field

[0001] The utility model relates to the technical field of medical equipment, and in particular to a stomach tube fixing device which can assist in fixing a stomach tube. Background Art

[0002] A gastric tube is a medical tube that delivers necessary water and food to patients who cannot swallow. The gastric tube is usually inserted through the mouth or nostrils and reaches the stomach through the esophagus. The significance of leaving a gastric tube is gastrointestinal nutritional support and gastrointestinal decompression. Through the gastric tube, medication or supplementary feeding can be given, and the stomach contents can be sucked out in time to understand the nature of gastric juice, reduce its acidity, prevent digestive clots, facilitate hemostasis, reduce gastrointestinal pressure, and facilitate wound healing.

[0003] Inserting a gastric tube is an invasive procedure. Due to the complex anatomical structure of the pharynx, local soft tissue damage and misplacement of the tube into the trachea are likely to occur during the procedure. Therefore, the gastric tube should be firmly fixed to prevent repeated insertion, thereby avoiding damage to the human body caused by repeated insertion.

[0004] At present, the conventional method of fixing the gastric tube is to use pins or clips to fix the gauze and clothes wrapped around the end of the gastric tube together. The patient's body position changes during sleep, which can easily press the clip or pin, causing the pin or clip to twist. On the one hand, the twisting of the clip or pin will cause poor fixation of the gastric tube and displacement of the gastric tube; on the other hand, the twisted pin or clip will squeeze and twist the gastric tube, which may cause the gastric tube to twist, deform or even break, increasing the rate of gastric tube removal, the risk of unplanned tube removal, and the damage to the patient caused by coughing, aspiration and repeated intubation caused by gastric tube slippage; and the clip or pin can easily injure the patient when the patient turns over, which poses a certain safety hazard. Utility Model Content

[0005] Therefore, the technical problem to be solved by the utility model is to overcome the technical defects in the prior art that the clips or pins used to fix the gastric tube are easily pressed against the gastric tube when the patient turns over, causing the gastric tube to be deformed and twisted, resulting in poor fixation of the gastric tube or even damage, and in severe cases, the patient needs to be repeatedly intubated, and the twisted and deformed pins or clips are also easy to injure the patient, thereby providing a gastric tube fixing device that can safely and firmly fix the gastric tube in vitro.

[0035] This embodiment provides a gastric tube fixing device, such as Figure 1-4As shown, it includes a clamping mechanism 1, a mounting rod 2 and a mounting seat 3; wherein the clamping mechanism 1 includes a cylinder with a certain length, a tube placement cavity 11 is formed inside the cylinder, a tube placement port 12 for placing a gastric tube into the tube placement cavity 11 is arranged on the side wall of the cylinder, the mounting rod 2 is arranged on the side wall of the cylinder, opposite to the tube placement port 12 up and down, and has a first limiting portion 21; the mounting seat 3 is provided with a mounting hole 31 suitable for inserting the mounting rod 2, and a second limiting portion 32 corresponding to the first limiting portion 21 is arranged inside the mounting hole 31; when the mounting rod 2 is inserted into the mounting hole 31, the first limiting portion 21 and the second limiting portion 32 can cooperate to limit the relative displacement of the mounting rod 2 and the mounting seat 3 in the axial direction.

[0036] The stomach tube fixing device of this embodiment, when in use, places the mounting seat 3 on the inside of the patient's clothes, places the mounting rod 2 on the outside of the patient's clothes, and then inserts the mounting rod 2 into the mounting hole 31 of the mounting seat 3, and the first limiting portion 21 and the second limiting portion 32 cooperate to limit the mounting rod 2 and the mounting seat 3, so as to fix the stomach tube fixing device to the patient's clothes; then, the stomach tube is placed into the tube placement cavity 11 through the tube placement port 12 on the clamping mechanism 1, and the stomach tube is fixed to the clamping mechanism 1. In this way, the stomach tube can be fixed to the patient's clothes by the stomach tube fixing device of this embodiment. The cylinder has a certain length, so that the inside and outside of the cylinder have a large surface area. When the patient's body presses on the cylinder, the large outer surface area of ​​the cylinder can reduce the pressure on the patient's body and avoid injury to the patient. At the same time, the large inner surface area of ​​the cylinder can better support the stomach tube and prevent the stomach tube from bending and twisting.

[0037] In the stomach tube fixing device of this embodiment, the first limiting portion 21 is an annular protrusion formed on the outer wall of the mounting rod 2; the second limiting portion 32 is an annular protrusion formed on the inner wall of the opening of the mounting hole 31.
