Dual-cavity stomach and intestine drainage tube

The utility model relates to the technical field of medical instruments, in particular to a dual-cavity stomach and intestine drainage tube. The drainage tube consists of a head part (1), a body part (2) and a tail part (3), wherein the body part (2) is a round dual-cavity tube, and scales are arranged outside the tube wall so as to know the length inserted into the human body; the tail part (3) of the drainage tube braches off into a drainage tube port (31) and an infusion set port (32); the drainage tube port (31) is connected with a wider tube of the body part, and the infusion set port (32) is connected with a thin tube of the body part; the head part (1) of the drainage tube braches off into two tubes in different widths, wherein the two tubes are respectively communicated with the two tubes in corresponding width of the body part (2), the wider tube (11) is connected with the wider tube of the body part, drainage holes (4) are arranged at the two side walls of the two sides of the connecting position, and the thin tube (12) is connected with the thin tube of the body part. The drainage tube has simple structure and convenient use, can not only drain the stomach and intestine liquid fully after stomach and intestine anastomosis, but also has the action of early enteral nutrition after anastomosis, and improves the success rate and the quality of the anastomosis.
