  • Publication number: 20120118288
    Abstract: A breathing assistance apparatus adapted to deliver humidified gases at a desired level of humidity to a patient including a humidifier and a heated conduit is disclosed. The humidifier includes a controller which controls the humidifier, or the humidifier and the heated conduit to deliver the gases to the patient at the required humidity or temperature, without the requirement for sensors in the gases stream. The controller uses information already available to the controller, without the requirement for additional information to be provided by sensors in the gases stream. This means the need for sensors in the gases stream is dispensed with. A significant benefit is achieved as sensors are not required in the conduit and thus the apparatus is simple and less bulky.

  • Patent number: 8122882
    Abstract: A breathing circuit includes inspiratory and expiratory limbs, each having a respective electrically energizable heating circuit. The heating circuits are independently and selectively electrically energized through separate power circuits such as to control the temperature in each limb in a desired fashion so as to reduce rainout in the breathing circuit and particularly in the expiratory limb.

  • Patent number: 8091545
    Abstract: Containers for incrementally dispensing pressurized contents are described. The containers comprise a vessel suited to contain pressurized contents, a port integral with the vessel and through which pressurized contents contained in the vessel can be released from the vessel, preferably incrementally in approximately equal amounts, and a measuring device disposed in or otherwise associated with the vessel such that the quantity or amount of contents in the vessel can be measured or assessed. The measuring device senses ambient conditions in the vessel and, directly or with other components, indicates, for example, the amount of pressurized contents remaining in the vessel and displaying it to an observer. Devices for incrementally dispensing pressurized contents from such containers are also described.

  • Patent number: 8037882
    Abstract: A conduit for a breathing circuit includes a heater associated, at least in part, with a hydrophilic layer. The purpose of the heater is to evaporate any condensed liquid collecting in the conduit, which is first sucked up by the hydrophilic layer. The heated wick reduces the risk of collected water being passed to the patient and causing choking fits or discomfit. It is preferred that the heated wick lies freely in the conduit to settle at low points in the conduit where condensation may collect.

  • Patent number: 8015969
    Abstract: A conventional respiratory nebulizer has an emergency medication dose storage system delivering the stored medication dose directly to the nebulizing chamber with a single impulse of manual force to a simple mechanical delivery system, thereby making the nebulizer useable in two steps: (a) opening the medication capsule with a simple opening action; and (b) inhaling the nebulized medication. The nebulizer can be operated without disassembling the nebulizer housing so as to expose the nebulizing chamber and without manually opening the liquid medication container and, without spillage and without manual pouring of the liquid medication directly into the nebulizing chamber, and without reassembling the nebulizer housing before positioning the inhaler mouthpiece in the mouth so as to inhale the nebulized medication. The delivery system includes a pressure burstable seal at one end of the capsule, which is burst by the application of force against the opposite end of the capsule.
