  • Publication number: 20210170126
    Abstract: A catheter mount is configured to be attached to a respiratory apparatus. The catheter mount includes a plurality of ports in fluid communication with each other. The plurality of ports include an interface port configured to connect to an interface tube, a conduit port configured to connect to a conduit tube, and at least one suction port configured to allow insertion of a suction catheter. The at least one suction port can be positioned to allow the suction catheter, when inserted, access to both the interface port and conduit port.

  • 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: 20200289780
    Abstract: Connectors for respiratory assistance systems are disclosed that are configured to at least decrease the proportion of condensate that drains into an inspiratory conduit. The connectors include a setup that causes the portion of a wye-piece connected to an expiratory conduit to be positioned below the portion of the wye-piece connected to the inspiratory conduit. The connector can alternatively, or additionally, include a wye-piece that includes a ball attached to the wye-piece adjacent the inspiratory conduit port such that when the ball is connected to a medical stand, the expiratory conduit port is positioned below the inspiratory conduit port. The connector can alternatively or additionally include a circuit hanger that includes a cradles for both conduits and a ball attached to the circuit hanger adjacent the inspiratory conduit cradle such that when the ball is connected to a medical stand, the expiratory conduit cradle is positioned below the inspiratory conduit cradle.

  • Publication number: 20200289783
    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.

  • Publication number: 20190125993
    Abstract: This invention relates to a breath indicator that is receivable by a part of a breathing assistance apparatus that supplies gas to a patient. The indicator comprises an elongate body having a gas sampling end and an attachment end. The attachment end is adapted to attach to a part of a breathing assistance apparatus and for locating the gas sampling end. The gas sampling end is to be located in a region where gas from the patient is to be exhaled. The gas sampling end being in communication with a sensor comprising a detector material changeable between a first visual indicator state relating to an inhalation phase of the patient, and a second visual indicator state relating to an exhalation phase of the patient. The detector material is capable of changing between the visual indicator states at a sufficient rate to substantially correspond with the inhalation and exhalation phases of the patient.

  • Publication number: 20190111229
    Abstract: A wye connector has a patient coupling end. The patient coupling end has a first connector surface and a second connector surface. The first connector surface has a first diameter at an axial location along the patient coupling end. The second connector surface has a second diameter at the same axial location along the patient coupling end. The first diameter is larger than the second diameter.
