Description

Technical Field

[0002] A gastric tube (nasal-gastric tube, nasogastric feeding) is inserted through the nostril, passes through the pharynx and esophagus to reach the stomach through the gastric tube. It is mostly used to aspirate gastric juice, wash the stomach in case of acute poisoning, and can also be used to inject liquid into the stomach to provide the patient with necessary food and nutrition. During nursing, attention should be paid to avoiding contamination of the gastric tube and the gastric tube falling out, resulting in aspiration. In the department of neurology, it is common in patients with dysphagia caused by bulbar palsy, and stroke is one of the common causes. In order to ensure their nutritional needs, maintain water and electrolyte balance and drug application, and promote disease recovery, nasogastric feeding is required.

[0003] In the prior art, since a nasal-gastric tube fixing device is used when using a nasal-gastric tube, and the nasal-gastric tube fixing device is composed of a nasal-gastric tube body, a cover body, a connection hole, and an ear strap assembly, it is necessary to connect the external nasal-gastric tube to the nasal-gastric tube body at the position of the connection hole of the nasal-gastric tube fixing device during use. At this time, the nasal-gastric tube fixing device is worn on the ear through the ear strap, so that the use of the nasal-gastric tube fixing device can be completed. However, when the nasal-gastric tube fixing device is worn on the ear through the ear strap, the ear strap has elasticity, so that the ear strap can adapt to more scenarios. However, due to long-term use, the elasticity of the ear strap will be affected, thus affecting the wearing of the nasal-gastric tube fixing device and resulting in the inability to perform subsequent treatment through the nasal-gastric tube fixing device.
