Background
Breathing assistance apparatuses or systems that provide a humidified and heated flow of gas to a patient for therapeutic purposes have been widely used, and systems that provide such therapy (e.g., respiratory humidification) typically deliver gas to a humidifier chamber from a gas source, which may be a blower (also known as a compressor, assisted breathing apparatus, fan apparatus, flow generator, or pressure generator). The gas is saturated with water vapor as it passes over the hot water in the humidifier chamber, or through the heated and humidified air. The heated and humidified gases are then delivered to a user or patient downstream of the humidifier chamber via breathing tubing and a user interface.
The heating of the breathing pipeline can heat or preserve the temperature of the gas flowing through the pipeline on the one hand, and on the other hand, the more important purpose is to solve or relieve the problem that the heating and humidifying gas flow flowing through the pipeline generates condensed water on the pipe wall.

One is a common corrugated pipe, and a spiral heating wire is arranged in a cavity of the pipeline; the other is that the heating wire and the pipeline are integrated into a whole, and the heating wire is fixedly attached to the pipe wall. The heating effect of the heating wire is not uniform, and the effect of preventing the condensed water is limited by the structure, so that the generation of the condensed water cannot be effectively prevented under the condition of lower room temperature.
