Breathing tube, medical apparatus, and processing method

Abstract

Provided are a breathing tube, a medical device, and a manufacturing method. The breathing tube includes a gas guide tube and a first support rib. The gas guide tube is configured to convey a gas. The first support rib is connected to an outer peripheral wall surface of the gas guide tube and disposed around an axis of the gas guide tube. The first support rib that is partially hollowed out has lower thermal conductivity, so as to enhance the heat preservation and insulation effects for a flowing medium, thereby reducing the amount of condensate water caused by a temperature difference on the tube wall.
