Description

Technical Field

[0001] The utility model relates to the technical field of medical instruments and in particular to a novel gastric tube indwelling device. Background Art

[0002] Gastric intubation is a commonly used medical care technique in clinical practice. Indwelling gastric tubes are mainly used for nasogastric feeding or gastrointestinal decompression. In clinical practice, adhesive tape is routinely used to fix the gastric tube on both sides of the nose and cheeks, but the adhesive tape is prone to problems such as loose fixation and skin allergies. In the existing technology, a fixing belt is often used to wrap around the patient's brain and then fix it by gluing or tying it, which has a poor fixing effect.
