The utility model belongs to the technical field of auxiliary medical devices, in particular to a spray type trachea cannula applied to the preservation of a non heart heating donor lung. The spray type trachea cannula consists of an airbag injection port, a temperature sensor, a fixing bracket, a pressure measurement point outlet, an expansion nozzle with micropores, an airbag, a pressure sensor, a data acquisition module, a cannula body of the trachea cannula, a pressure determination extension tube, a nozzle extension tube, a temperature determination extension tube and a computer. According to the spray type trachea cannula, low-temperature protection fluid can be sprayed in a trachea, the specific heat non-uniformity of the trachea, a lung tissue and a gas can be weakened, temperature in the trachea and the temperature of the lung can be quickly reduced, warm ischemia damage is alleviated, and the quality of the donor lung is improved; and temperature and pressure conditions in the trachea can be monitored in real time, and each parameter index can be timely regulated to ensure the safe and effective cooling of the donor lung.
