Breathing tube with mesh

A medical tube comprises a tail to connect an embedded wire to an electrical component. The tail may comprise a flattened portion and an exposed portion to facilitate attachment of the medical tube to an electrical component. The tail may comprise a second flattened portion. One or more wires, such as a heater wire or a sensor wire, may be embedded in the medical tube. The medical tube may comprise a connector that comprises a printed circuit board to which the one or more wires is attached. The connector may comprise features to support the printed circuit board, aid in assembly of the one or more wires to the connector, and protect electrical components against liquid ingress.

Medical tubes for respiratory systems

Some embodiments provide for an inspiratory limb for a breathing circuit that includes a first segment that comprises a first heater wire circuit and a second segment that comprises a second heater wire circuit. The inspiratory limb can include an intermediate connector that includes a connection circuit that electrically couples the first heater wire circuit to the second heater wire circuit. The inspiratory limb can be configured to operate in two modes wherein, in a first mode, electrical power passes through the first electrical connection to provide power to the first heater wire circuit without providing power to the second heater wire circuit, and in a second mode, electrical power pass through the first electrical connection to provide power to both the first heater wire circuit and the second heater wire circuit.

Zone heating for respiratory circuits

Circuit kit for a humidifier

Medical tubes and methods of manufacturing medical tubes are disclosed, such as in positive airway pressure (PAP), respirator, anaesthesia, ventilator, and insufflation systems. The tube may be a composite structure made of two or more distinct components spirally wound to form an elongate tube. One of the components may be a spirally wound elongate hollow body, and the other component an elongate structural component spirally wound between turns of the spirally wound hollow body. Alternatively, the tube need not be made from distinct components. For instance, an elongate hollow body formed (e.g., extruded) from a single material may be spirally wound to form an elongate tube. The elongate hollow body itself may in transverse cross-section have a thin wall portion and a relatively thicker or more rigid reinforcement portion. The tubes can be incorporated into a variety of medical circuits or have other medical uses.
