双腔鼻胆引流管Double lumen nasobiliary drainage tube

技术领域technical field

本实用新型涉及医疗器械技术领域，具体地说是一种既可以将胆汁引流到肠腔内，也可以将胆汁引流到体外的双腔鼻胆引流管。The utility model relates to the technical field of medical devices, in particular to a double-cavity nasobiliary drainage tube which can drain bile into the intestinal cavity and drain the bile out of the body.

背景技术Background technique

急性梗阻性化脓性胆管炎是消化内科常见的急重症，对于上述病症，尽快解除胆道梗阻，引流化脓胆汁是首要治疗措施。目前，内镜下鼻胆管引流术（Endoscopic Nasobiliary Drainage，ENBD）为首选治疗。Acute obstructive suppurative cholangitis is a common acute and severe disease in the Department of Gastroenterology. For the above-mentioned diseases, relieving biliary obstruction as soon as possible and draining suppurative bile are the primary treatment measures. Currently, endoscopic nasobiliary drainage (ENBD) is the preferred treatment.

ENBD是一种简便有效的胆汁外引流方式，它是通过内镜技术将鼻胆管前端放入胆道，另一端从鼻引出，通过鼻胆引流管可以引流出胆管内的感染性胆汁，解除胆道梗阻，消退黄疸，控制炎症，而且通过鼻胆引流管可反复冲洗、药物灌注，有效改善患者病情。ENBD is a simple and effective way of external bile drainage. It uses endoscopic technology to put the front end of the nasobiliary duct into the biliary tract, and the other end is led out from the nose. The infectious bile in the bile duct can be drained through the nasobiliary drainage tube to relieve biliary obstruction. , subside jaundice, control inflammation, and through the nasobiliary drainage tube, repeated washing and drug infusion can effectively improve the patient's condition.

随着技术的更新，目前应用于临床的鼻胆引流管已不容易从胆管中脱出，引流效果明显。但是这些鼻胆引流管只能起到胆汁外引流的作用，即胆汁由胆管内引流到体外。胆汁中含有大量的胆盐和磷脂等有益物质，胆汁丢失过多容易导致水、电解质平衡紊乱和营养不良。对于胆系梗阻或高龄的化脓性胆系结石并感染的患者，过度的胆汁外引流导致胆汁的大量丢失，不利于疾病的恢复。With the updating of technology, the nasobiliary drainage tube currently used in clinical practice is no longer easy to detach from the bile duct, and the drainage effect is obvious. But these nasobiliary drainage tubes can only play the role of bile external drainage, that is, bile is drained from the bile duct to the outside of the body. Bile contains a lot of beneficial substances such as bile salts and phospholipids. Excessive loss of bile can easily lead to water and electrolyte balance disorders and malnutrition. For patients with biliary obstruction or elderly patients with suppurative gallstones and infection, excessive external drainage of bile leads to a large loss of bile, which is not conducive to the recovery of the disease.

Double-lumen nasobiliary drainage tube, including the main body of the drainage tube and accessories, the main body of the drainage tube includes a head 1 and a body 2, the head 1 is a double-lumen tube, and the head 1 includes anexternal drainage pipe 11 And theinner drainage pipe 12; one end of theouter drainage pipe 11 is curved in an arc shape, the other end of theouter drainage pipe 11 is connected with the body 2, and the end of the curved part of theouter drainage pipe 11 is provided with a straight hole, and the curved part of theouter drainage pipe 11 Two groups of outer drainagepipe side holes 111 are provided on the side of theinner drainage pipe 12; The upper part is provided with fourside holes 121 of internal drainage pipes; the accessories includeexternal joints 3 and auxiliary devices 4 .

所述外接头3包括接头管31、垫片32和堵塞33，所述接头管31的结构为在一圆柱形管的一端设有锥形管构成，所述堵塞33与接头管31的圆柱形管部分相配合，垫片32位于接头管31与堵塞33之间。Theouter joint 3 includes ajoint pipe 31, agasket 32 and aplug 33. The structure of thejoint pipe 31 is provided with a tapered pipe at one end of a cylindrical pipe. The pipe parts fit together, and thegasket 32 is located between thejoint pipe 31 and theplug 33 .

所述辅助装置4为圆管，辅助装置4的两端对称的设有向外扩散的漏斗状结构。The auxiliary device 4 is a round tube, and the two ends of the auxiliary device 4 are symmetrically provided with funnel-shaped structures that diffuse outward.

所述的两组外引流管道侧孔111相互错开，每组外引流管道侧孔111的数量为四个且并列设置。The two groups of external drainagepipe side holes 111 are staggered from each other, and the number of each group of external drainagepipe side holes 111 is four and arranged side by side.

所述内引流管道上口122和内引流管道下口123相对于所述外引流管道11均呈斜角。斜角的设置避免放置及拔除引流管时损伤胆管、胃肠。Theupper opening 122 of the inner drainage pipe and thelower opening 123 of the inner drainage pipe are oblique to theouter drainage pipe 11 .

使用时，用辅助装置4取直引流管主体前端圆弧状弯曲成猪尾形状的部分，常规行内镜下鼻胆管引流术，通过内镜的活检通道，沿导丝将引流管主体插入胆道的相应位置，引流管主体另一端从鼻孔引出，接外接头3，引流管主体外固定。如不需要外引流时，将引流管外接头3关闭即可。When in use, use the auxiliary device 4 to take the part of the front end of the main body of the straight drainage tube that is bent into a pigtail shape in an arc shape, perform routine endoscopic nasobiliary drainage, and insert the main body of the drainage tube into the biliary tract along the guide wire through the biopsy channel of the endoscope. At the corresponding position, the other end of the main body of the drainage tube is drawn out from the nostril, connected to theexternal joint 3, and fixed outside the main body of the drainage tube. When external drainage is not needed, theexternal connector 3 of the drainage tube can be closed.

引流管主体放置后，胆汁既可以顺着外引流管道11引流到体外，也可以顺着内引流管道12流入十二指肠内，如需要较长时间的放置，可关闭外引流管道11，胆汁只顺着内引流管道12流入肠腔，避免了胆汁的过度丢失。另外头部自然状态下的圆弧形弯曲呈猪尾状，不易脱出胆道，当牵拉引流管主体的外力达到一定程度时，引流管主体头端顺势取直，利于引流管的拔出。After the main body of the drainage tube is placed, the bile can be drained out of the body along theexternal drainage tube 11, and can also flow into the duodenum along theinternal drainage tube 12. If it needs to be placed for a long time, theexternal drainage tube 11 can be closed, and the bile Only flow into the intestinal cavity along theinternal drainage pipe 12, avoiding excessive loss of bile. In addition, the arc shape of the head in the natural state is like a pigtail, which is not easy to protrude from the biliary tract. When the external force pulling the main body of the drainage tube reaches a certain level, the head of the main body of the drainage tube will be straightened to facilitate the extraction of the drainage tube.
