The present application relates to the technical field of micro-ecological diagnosis and treatment, and is a multi-chamber different point intestinal flora collection device, comprising a shell, a driving switching module and a plurality of circumferentially distributed sampling shells. The shell is designed in a split type, facilitating sample recovery; each sampling shell inlet is covered with a slow-release layer with different dissolution characteristics, which can respond to specific environmental parameters of different sections of the intestine. After a slow-release layer in the target intestinal section dissolves to trigger single-point sampling, the sampling shell is automatically driven to switch, allowing the next sampling shell to enter the working position. The device realizes automatic, time-sequential and multi-point precise sampling in a single intestinal journey, ensures independent and non-cross-contaminated samples at each point, and can obtain in-situ liquid samples at multiple points in the intestine, truly reflecting the spatial distribution heterogeneity and dynamic change rule of the flora, and providing key technical support for intestinal micro-ecological research, disease diagnosis and personalized treatment.
