Description

Technical Field

[0001] The invention relates to the technical field of pressure prevention and fixation, and in particular to a nasogastric tube fixation device for preventing pressure sores. Background Art

[0002] Nasogastric tubes are used to deliver necessary water, food, and medicine to patients who cannot swallow under special circumstances. They can drain gastric contents and reduce gastrointestinal pressure. Nasogastric tubes pass through the pharynx and esophagus to the stomach. Nasogastric tubes are easy to fall out and should be firmly affixed to prevent repeated intubation and aspiration. Most of the existing fixing methods are composed of tubes, nasogastric tube feeding port connectors, nasogastric tube clamps, and cross knot plug caps. Although this method can fix it, it ignores the nasal pressure sores caused by the retention of nasogastric tubes. Nasal pressure sores are more common in the wings of the nose and the tip of the nose, increasing the patient's skin discomfort, pain, and the chance of infection. Therefore, it is necessary to design a fixing device to fix the nasogastric tube on the patient, block the direct contact between the nasogastric tube and the nasal skin, reduce the pressure and stimulation of the nasal skin by the nasogastric tube, and achieve the purpose of preventing and treating the formation of nasal pressure sores.
