  • Patent number: 11878093
    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.

  • Patent number: 10648707
    Abstract: A thermoelectric dehumidification rod comprises a bendable heat-dissipation tube formed with a wave structure at the surface, a thermoelectric element set in the heat-dissipation tube, and a power cable. Both ends of the heat-dissipation tube are covered by an end cap, respectively. The power cable is through one of the end caps and electrically connected with the thermoelectric element. Accordingly, the thermoelectric dehumidification rod is bendable and has the closed tube to protect the thermoelectric element. Furthermore, the wave surface of the heat-dissipation tube increases its surface area, enhancing the dissipation effect. Moreover, the thermoelectric dehumidification rod could be put on the curved surface due to its bendable characteristic, shortening the linear length of the whole thermoelectric dehumidification rod, or in a space which size is smaller than the linear length of the unbended thermoelectric dehumidification rod, so it is convenient for use and has more economic benefit.

    Abstract: The present invention relates to an apparatus and method for maintaining patient temperature during an anaesthetic procedure. Patients, particularly small patients, can lose body temperature when undergoing surgery or other procedures where they are anaesthetised. The process of breathing the cool anaesthetic gas contributes to the temperature loss of the patient. An anaesthetic apparatus of the present invention is arranged to warm the gas being provided for the patient to breathe, to facilitate maintaining body temperature. An inspired limb of an anaesthetic circuit comprises tubing with a heating conductor for heating the inspired gas.

    Abstract: A mixer-heater device provides controllable reduction in aerosol droplet size. Additionally, an intermittent delivery mode for administering an aerosol to a patient may take into account patient expiration and reduce aerosol losses without prolonging treatment time. Depositional losses in aerosol delivery systems may be reduced by streamlining the three dimensional geometry of conduits which change stream direction or flow path diameter. Ventilation systems may also benefit from streamlined components, in particular Y-connectors, with resulting advantages such as reduced rebreathed CO2.
