Abstract
A breathing gas delivery pipe, a nasal catheter, and a ventilation therapy device, where the breathing gas delivery pipe is used for delivering gas to a patient interface, and includes a gas delivery pipe body including a gas delivery channel and a heat preservation structure used for preserving heat of the gas delivered in the gas delivery channel such that, the heat preservation structure preserves the heat of the gas delivery pipe body, so that the temperature drop in the gas delivery channel can be effectively slowed down or avoided, thereby a temperature drop of the gas delivered in the gas delivery channel is further slowed down or avoided, and the generation of condensed water in the gas delivery channel is avoided.
