一种新型胃肠营养管路的设计和应用

Design and application of a new gastrointestinal nutrition pipeline

胃肠营养管是针对重症患者进行肠内营养、诊断、治疗和监护而设计的专用胃肠管,临床上用于插入患者的胃部进行冲洗;或经胃、十二指肠或空肠进行营养供给和胃肠减压;还可用于对重症患者进行胃液引流、胃液pH值测定及胃出血等症状的早期诊断和治疗。但现有的胃肠营养管只能依靠导丝和外力进行盲插,或者借助胃镜插入,对患者的损害较大,容易刺激患者消化道黏膜,引起不良反应。为此,杭州市富阳区第一人民医院重症医学科的医护人员针对现有胃肠营养管存在的技术问题,设计了一种新型胃肠营养管路,并获得国家实用新型专利(专利号:ZL 2019 2 0118506.0),包括V型接头、第一管路、第二管路、功能模块、供给管、刻度线、上卡环、下卡环、椭圆球囊、弹性导丝和输液开口,具有多通道、多功能、多种置入方式的特点。与现有技术相比,本实用新型专利胃肠营养管路结构简单、设计合理,可以十分简便地插入患者胃肠道中给予营养液。

Gastrointestinal nutrition tube is a special gastrointestinal tube designed for enteral nutrition,diagnosis,treatment and monitoring in severe patients.Clinically,it is inserted into patients'stomach for flushing,provide nutrition through stomach,duodenum or jejunum,and decompress gastrointestinal tract.It also can be used for gastric drainage,gastric juice pH value determination,and early diagnosis and treatment for stomach bleeding and other symptoms.Currently,gastrointestinal nutrition tube can only rely on guidewire and blind manipulation,or by gastroscopy,which may produce damage to the patients,including stimulating the digestive tract mucous membrane,and causing adverse reaction.Therefore,a new type gastrointestinal nutrition line was designed by the medical staff of intensive care unit(ICU)of the First People's Hospital of Fuyang District in Hangzhou according to the technical problems existing in the insertion of gastrointestinal nutrition tube,and National Utility Model Patent of China was obtained(ZL 201920118506.0).It included V-shaped joint,first pipe,second pipe,function module,supply pipe,scale line,upper clasp,lower clasp,elliptical balloon,elastic guide wire and infusion opening.Compared with the existed technology,it has multiple channels,functions and placement methods.The utility model has a simple structure and reasonable design,which can be very handy to insert and provide nutrient solution.
