  • Publication number: 20210361901
    Abstract: A connector and tubing combination includes a tubing segment with an end piece, such as a tubing flange. The tubing flange can be secured within the connector by an outer sleeve and an inner sleeve of the connector. Both of the inner sleeve and the outer sleeve are located outside of the tubing flange and the tubing segment. In addition, the inner sleeve, outer sleeve and the tubing flange are mechanically connected.

  • Patent number: 11173269
    Abstract: An adaptor for a respiratory assistance system delivers aerosols to a patient. The adaptor is lightweight with a small footprint to increase patient comfort. The adaptor has a nozzle and a sealing mechanism to maintain pressure therein regardless of whether the nozzle is inserted into the adaptor. The adaptor is configured to connect to medical tubing and a medicament delivery device.

  • Patent number: 11052215
    Abstract: A medical tube has a tube wall, a first end and a second end. At least one heater wire is wrapped around the wall. Near or at one of the first end or the second end, there is at least one recess in an outer surface of the wall. The heater wire passes over the at least one tube recess such that the wire does not contact the wall in the area of the tube recess. Also disclosed are methods of making the tube and components used in making the tube.

  • Patent number: 10960167
    Abstract: 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.

  • Publication number: 20210069447
    Abstract: This invention relates to a medical tube comprises an elongate conduit having a first opening, a second opening, a longitudinal axis, a lumen extending between the first opening and the second opening along the longitudinal axis, and a corrugated wall, formed from an extruded material, extending between the first opening and the second opening and surrounding the lumen. The wall is stiffer in a first length of the conduit adjacent the first opening than in a second length of the conduit adjacent the second opening. The variable stiffness of the tube wall can improve the thermal profile of the tube as well as improve drain-back of condensation into a humidifier providing humidified gas to the tube.

  • Publication number: 20200289782
    Abstract: Condensation or “rain-out” is a problem in medical circuits and previous attempts to manage and/or prevent rain-out have resulted in relatively expensive and/or difficult to manufacture medical circuit components. The subject patent provides an improved medical circuit component for managing rain-out. In particular the component may be an improved breathing tube, or insufflation system limb comprising a helically corrugated tube preferably incorporating a heater wire.
