The invention relates to a thyrocricoid puncture aeration device. The device comprises a puncture needle, a connecting pipe and a fixator; the puncture needle comprises a puncture needle outer casing and a rigid needle core arranged inside the puncture needle outer casing, a casing body of the puncture needle outer casing is a nonmetallic hose, and forms pig tail bending in a natural state, the rigid needle core is arranged inside the puncture needle outer casing to make the inside the puncture needle outer casing keep a straight state, and a pipe mouth of the connecting pipe is used for being connected to a respirator. In the thyrocricoid puncture aeration device, the overall puncture needle forms a penholder-shaped solid needle body through the coordination of the nonmetallic puncture needle outer casing and the stainless steel needle core, the puncture needle can fast, directly and stably conduct puncture in place, and unnecessary damage of an air passage caused by the puncture needle is avoided. When the needle core is drawn out, the puncture needle outer casing fast bends naturally, and forms pig tail bending shown in the description, thus the overall puncture needle outer casing can be stably fixed in the air passage, slip and falling and blockage are avoided, aeration is smooth, attraction id sufficient, and the device is suitable for various air passages.
