  • Publication number: 20240399097
    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.

  • Patent number: 12121668
    Abstract: In some embodiments, a humidification system includes a heater base having a heater plate, a humidification chamber, and circuit. The circuit can include various conduits, including an inspiratory conduit, expiratory conduit, Y-piece, patient conduit, and/or dry conduit. In use, the chamber contains a quantity of liquid. The heater base heats the heater plate, which in turn heats the liquid to a temperature that causes at least some of the liquid to become vapor, thereby humidifying the gases within the chamber. The gas is delivered to the patient via the inspiratory conduit. Various features can help control the system and ensure the patient receives gases having the desired conditions. These features can be used individually or in various combinations and subcombinations both in existing humidification systems and improved systems for respiratory humidification, laparoscopy, and other purposes.

  • Publication number: 20240189531
    Abstract: A patient ventilating (23) and aspirating system (9) is disclosed that has a suction tube (9) and connector (6) for connecting to a catheter mount that has a sealed passageway (15). The catheter mount passageway (15) is sealed with an elastomeric seal (16) including a perforation or slit (17). A connector (12) with a piercing member is associated with the suction tube (9). When the connector is attached to the catheter mount the piercing member (20) pierces the seal (16) such that the suction tube (9) can pass through the connector (6) and catheter mount.

  • Publication number: 20220379054
    Abstract: This invention provides for a component forming a part of a breathing tube, or forming the breathing tube, for example as a part of a breathing circuit for respiratory therapy. The component comprising a tubular body having a foamed wall. The foamed wall can be formed from extrusion of a single extrudate. The foamed wall is of a sufficient minimum optical transparency such that, in use, there is enabled the visual detection of a liquid (or condensate that may have formed) within the tubular body.

  • 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.
