Description
技术领域technical field
本发明涉及一种胃管，特别是关于一种带防反流气囊及咽部吸引侧孔的胃管。The invention relates to a gastric tube, in particular to a gastric tube with an anti-reflux air bag and a suction side hole in the pharynx.
背景技术Background technique
胃管是医院各科经常使用的医疗器械，经由鼻腔插入，然后依次经咽部和食管到达胃部。对于各种原因(如神经系统疾患、气管插管等)导致的不能经口进食的患者，常常需要长期留置胃管以保证营养物质、药物和水的摄入。吸入性肺炎是留置胃管的常见并发症，是导致住院时间延长、医疗费用增加、死亡率增加的重要原因。胃内容物反流入食管后到达口咽部引起的误吸以及由于口咽部分泌物积聚导致的微误吸是导致这些患者发生吸入性肺炎的重要原因。而传统的胃管不具备预防胃内容物反流和吸引清除咽部分泌物的功能，在发生胃内容物反流或口咽部分泌物积聚时，发生吸入性肺炎几乎不可避免。因此，如何能够降低反流误吸的发生，减少吸入性肺炎的风险，是临床上迫切需要解决的难点。Gastric tube is a medical device often used in various departments of the hospital. It is inserted through the nasal cavity, and then passes through the pharynx and esophagus to reach the stomach. For patients who cannot eat orally due to various reasons (such as nervous system disorders, endotracheal intubation, etc.), it is often necessary to indwell a gastric tube for a long time to ensure the intake of nutrients, drugs and water. Aspiration pneumonia is a common complication of indwelling gastric tube, and it is an important cause of prolonged hospital stay, increased medical expenses, and increased mortality. Aspiration caused by reflux of gastric contents into the oropharynx and microaspiration due to accumulation of secretions in the oropharynx are important causes of aspiration pneumonia in these patients. The traditional gastric tube does not have the function of preventing gastric reflux and attracting and clearing pharyngeal secretions. When gastric reflux or oropharyngeal secretions accumulate, aspiration pneumonia is almost inevitable. Therefore, how to reduce the occurrence of reflux aspiration and reduce the risk of aspiration pneumonia is an urgent problem to be solved clinically.
