Heated breathing tube for patient has heating element formed by tube wall and consisting of layer of electrically conductive synthetic material, voltage supply line integrated into tube wall

摘要

The device has a flexible tube wall (1) and a heater with a heating element made of electrically conductive synthetic material (a). The heating element is formed by the tube wall and consists of a layer of the electrically conductive synthetic material. The conductive layer can be arranged in the inner region of the tube wall or in its outer region and a voltage supply line is integrated into the tube wall.
