Abstract
A heatable air delivery tube that maintains the temperature within the tube includes a patient interface end, an airflow generator end, and a heated spiral tube with metal wires that connects the two ends. The patient interface end includes a notch that allows for deformation to better achieve a seal when connected to other tubular connectors. The airflow generator end has a deformable connecting clamp, which allows for self-deformation to secure a snap-fit connection with the airflow generator. The inner diameters of the connectors of both the patient interface end and the airflow generator end are no larger than the tubular connectors they connect to, to ensure a better seal.
