Description

Technical Field

[0001] The utility model belongs to the technical field of medical devices, and particularly relates to an anti-falling device for fixing a gastric tube. Background Art

[0002] A gastric tube is a nursing tool that helps patients who cannot swallow to deliver necessary water and food under special circumstances. It is generally made of polyurethane or silicone material. The gastric tube needs to be replaced once a month. It has different specifications for thickness, length, and is divided into orogastric tube and nasogastric tube. Among them, the orogastric tube is about 45 cm long and can be inserted 35 to 40 cm through the mouth, while the nasogastric tube is about 105 cm long and needs to be inserted about 55 cm through the nostrils. The nasogastric tube passes through the pharynx and the esophagus to reach the stomach. The nasogastric tube is easy to fall out and should be firmly affixed to prevent repeated intubation and aspiration. When intubating, position the patient, clean and lubricate the nasal cavity, tilt the patient's head back, and insert the gastric tube at a 60° angle to the nostril. After the gastric tube is successfully inserted, it needs to be properly fixed.

[0003] Currently, nasogastric tubes are mainly fixed by cross-fixing them on the nose wings with adhesive tape strips. However, due to the limited stickiness of the adhesive tape strips, it is easy to cause the tube to shift or even detach. Utility Model Content

[0004] In view of the deficiencies in the prior art, the purpose of the present invention is to provide an anti-falling device for fixing a gastric tube. After the gastric tube is aligned with the perforation and passed through the connecting plate and the conical ring, the connecting plate is placed close to the nostril, and the nut sleeve is rotated to move away from the connecting plate. Multiple units continuously squeeze the gastric tube toward the middle, hugging the gastric tube to achieve restriction of the gastric tube. At the same time, the elastic band can pass through the top of the patient's ear and hang it on the ear. Since the ear is higher than the nose, the elastic band can lift the connecting plate. At the same time, the elastic band is wrapped from behind the ear to the chin, and the middle part of the elastic band is hung under the chin to restrain the elastic band and prevent it from falling off, thereby indirectly restraining the gastric tube.
