  • Publication number: 20220273904
    Abstract: A humidifier liquid chamber or a humidifier liquid chamber manifold has first and second base unit connection ports 157, 159 for connecting to a breathing assistance apparatus base unit, the base unit connection ports defining respective axes A1, A2. The base unit connection ports are substantially parallel to each other and are separated by a port separation distance PSD between the axes. At least one of the base unit connection ports 157, 159 has a sealing depth SD defined by a portion of the port that is configured to overlap with a complementary chamber connection port of the base unit. A ratio of the sealing depth SD to port separation distance PSD is more than about 0.25.

  • Patent number: 10512702
    Abstract: The present invention provides a breathing assistance apparatus that has a convenient and effective method of cleaning internal conduits inside the apparatus. The breathing assistance apparatus is preferably a gases supply and humidification device. The cleaning method is a method of disinfection that is automated so minimal training is required to disinfect in particular an internal elbow conduit within the device. It is therefore not necessary to dismantle the gases supply and humidification device, therefore, inadvertent damage to the internal parts of the device is avoided. The present invention also provides a method of disinfecting a heated breathing conduit and a patient interface.

  • Publication number: 20140345615
    Abstract: The breathing assistance apparatus of the present invention includes a manifold that is provided with or retrofittable to gases supply and humidifying devices. The manifold allows gases from an oxygen concentrator to be combined with the flow through a gases supply and humidifying device, most usually air The combined output of oxygen and other breathing gases (air) is then humidified. The breathing assistance apparatus and manifold of the present invention provides a safe method to add oxygen to the input air stream of a gases supply and humidifying device and reduces the amount of accumulation of oxygen within the gases supply device, reducing fire risk should sparking occur within the device.

  • Patent number: 6454513
    Abstract: Device comprising two linkage mechanisms each having at least three bars (B11, 21, 51) of which a first and a second bar with the same length extend parallel to each other and are pivotably interconnected by at least a third bar. The two first and two third bars of both mechanisms are pivotably connected at a common main pivot (MP). Hinge point (HP1, HP2) of the first bars lying away from the main pivot are independently movable along linear paths. The device is further provided with a tool (T) comprising the main pivot. The first and second bars of each mechanism are pivotably connected by a fourth bar (B41, 42), lying parallel to and having the same length as the third bar. The fourth bar is rotatable about the hinge point of the first bar.
