Bypass device used for intestinal juice drainage

The invention discloses a bypass device used for intestinal juice drainage. According to the technical scheme, the bypass device is characterized by comprising a drainage hose and a fixed component, wherein the fixed component is arranged at one end of the drainage hose in the length direction, can fixedly fit the inside of the intestinal wall, and is made from an elastic material and made into acolumnar structure, the deformation direction of the fixed component at least comprises a radial direction, and the fixed component can support the inside of the intestinal wall in the radial deformation process; the middle of the fixed component is provided with a through hole capable of being communicated with the drainage hose, and the through hole runs through the two ends of the fixed component in the length direction. The bypass device can prevent intestinal juice from flowing through the anastomotic stoma of the intestinal tract, and infection is reduced. 本发明公开了一种用于肠液引流的转流装置，其技术方案要点是包括有导流软管和设置在导流软管长度方向一端并且能够固定贴
