  • 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: 20240342425
    Abstract: A humidification system for delivering humidified gases to a user can include a heater base, humidification chamber having an inlet, outlet, and associated fluid conduit, and breathing circuit including a supply conduit, inspiratory conduit, and optional expiratory conduit. The humidification system can include various features to help make set-up less difficult and time-consuming. For example, the supply conduit, inspiratory conduit, and optional expiratory conduit can be coupled into a one-piece circuit to aid set-up. Various components can be color-coded and can have corresponding structures to indicate which components should be connected to one another during set-up. Such features can also help make the set-up process more intuitive for an operator, which can reduce the need for specialized training and reduce the number of potential errors.

    Abstract: A system for humidifying respiratory gases has a humidification apparatus, a humidification chamber, a heating apparatus and a sensor. The sensor is configured to determine a characteristic of the gases flow and communicate this to a controller which controls the power supplied to the heating apparatus with respect to information regarding the characteristic of the gases flow. A structure partially encloses the humidification chamber and allows energy loss through a wall of the humidification chamber. The humidification chamber may have features to promote heat loss through the wall of the chamber.

  • Publication number: 20210069448
    Abstract: A respiratory system provides conditioned respiratory gases to a patient within a controlled temperature environment. A humidification apparatus has an inspiratory tube that may extend to a patient interface. The inspiratory tube may have a reduced length. A thermal insulation component may insulate at least a portion of the inspiratory tube. As a result, less of the inspiratory tube may be exposed to the surrounding ambient environment, which may reduce condensate formation within the inspiratory tube and heat loss to the surrounding ambient environment. The humidification apparatus may be directly coupled to the controlled temperature environment.
