The invention discloses a reinforced-fixed temperature measuring pleuroperitoneal cavity drainage tube, which comprises a drainage tube body, a temperature sensor, a temperature sensing line, a temperature detector, fixed airbags, gas injection paths and check valves, wherein side holes are formed in the first part of the drainage tube body; the temperature sensor is arranged on a first scale position of a second part of the drainage tube body; the temperature sensing line is connected to the temperature sensor and the temperature detector; and the temperature sensing line and the drainage tube body are closely stuck. The reinforced-fixed temperature measuring pleuroperitoneal cavity drainage tube provided by the invention, when achieving a drainage function, can synchronously conduct continuous and accurate deep temperature monitoring, and the drainage tube can be fixed in a reinforced mode; two treatment monitoring purposes can be achieved by implementing operations once; and the drainage tube can be effectively prevented from getting fallen.
