The utility model relates to a double-chamber T-tube which can recover bile, characterized in that the main vertical section of the double-chamber T-tube is a T-tube and the parallel section is a T-arm. There are two lumens in T-tube, the large lumen and the large lumen in T-arm are the same as the drainage bile; the small lumen in T-arm segment forms a free long separate tube which passes through the outlet of one side of T-arm segment, and communicates with the small lumen in T-tube wall, which is the same as the bile retransfusion pathway. The small lumen is equipped with a guide wire, which can be used to transport the small lumen into the duodenum; and the small lumen in the middle and lower part of T-tube is connected with the small lumen. There is a one-way valve on the wall. The opening direction of the one-way valve is the small lumen. When the outlet of the large lumen is clamped, bile flows from the one-way valve into the small lumen and enters the duodenum for bile reinfusion. Two outlets are connected at the other end of the T-tube, and the biliary drainage, biliary reinfusion and rinsing of the reinfusion pipeline are carried out respectively. The invention can not only ensure the smooth drainage of bile after operation, but also effectively return bile to the intestine, thereby achieving the goal of accelerating rehabilitation.
【技术实现步骤摘要】
胆汁回输型双腔T型管所属
本专利技术涉及一种在医疗领域为病人进行胆道探查手术时需要使用的可回输胆汁的双腔T型管,为一次性医疗用物。
技术介绍
胆管结石,胆道炎症,各种原因导致的胆道梗阻均需要行胆道探查,T管引流术。目前国内各大医院使用的T管为乳胶制品,由两个“臂”和一个长的引流管组成,上述三个组成部分彼此相通,形似T字而得名。(手术中将T管的臂放置在病人的胆总管内,T管引流管通过病人右侧肋缘下的腹壁到体外,缝合固定在皮肤上,胆汁通过T臂一部分流入肠道另一部分流入T管到引流袋。放置T管的目的:1引流胆汁,减轻胆道压力2支撑胆道,避免胆总管切口瘢痕形成导致管腔狭窄。3作为预留通道,为术后行逆行胆道造影或纤维胆道镜取石的重要途径。胆汁内含大量的胆盐、胆汁酸及多种脂溶性维生素,对维持肠道的酸碱平衡和胃肠功能有重要作用,正常人每天可分泌胆汁约800~1200mL,但绝大部分由小肠及回肠重吸收,仅有150mL随粪便排出体外。T管引流术后的患者在拔除T型管前,尤其是恶性梗阻型患者累计胆汁丢失量高达5000~10000mL,大量胆汁流失导致水、电解质与酸碱平衡紊乱,影响脂肪的消化、脂溶性维生素的吸收、肠黏膜屏障的结构与功能的完整性及肠道菌群的平衡。胆汁回输是将引流出或漏出的胆汁收集在无菌容器内,直接或经处理后回送到患者胃肠道内进行再利用的一种方式,其主要目的是促进患者对胃肠道内营养物质的消化吸收,增加肠蠕动,刺激内脏神经支配消化道和消化道激素的分泌,同时保护胃肠道的正常菌群和免疫系统,对维持胃肠道的功能,保护肠黏膜屏障和减少细菌移位具有重要意义。目前临床上采用的胆汁回输方 ...
