Patent number: 7263994Abstract: A flow probe for use in a humidification system is positioned in a humidified gases flow such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors into the gases flow. The flow probes are shaved and aligned within the gases flow to enable accurate gas flow readings to be taken whilst reducing the occurrence of condensation on the sensors. The flow probe can also be included in a humidification control systems to provide a patient with a desired humidity level or simplify the amount of user input required to set humidity levels. Furthermore, the flow probe can provide a controller with flow information which may then be used to determine certain conditions that could prove to be dangerous to a patient.Type: GrantFiled: September 17, 2003Date of Patent: September 4, 2007Assignee: Fisher & Paykel Healthcare LimitedInventors: Lewis George Gradon, Stephen William McPhee, Paul John Seakins, Peter John Leonard

Patent number: 7051733Abstract: A humidification apparatus for humidifying a gas flow to be supplied to a patient or other person in need of such gas is provided. A first temperature sensor is provided for sensing the temperature of the gas flow substantially at an outlet of a humidification chamber and a second temperature sensor is provided for sensing the temperature of the gas flow substantially at the patient end of the conduit. A display is provided for display of temperature information to a user. A controller or processor is configured or programmed to receive input from the temperature sensors and to output a signal to the display to cause a temperature to be displayed to the user which is the lower of the temperature sensed by temperature sensors.Type: GrantFiled: October 23, 2003Date of Patent: May 30, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Lewis George Gradon, Stephen William McPhee, Paul John Seakins, Peter John Leonard

Patent number: 7043979Abstract: A housing for a sensor to prevent condensate from collecting in the sensor. The housing includes a deflector to channel condensate forming in the housing away from the sensor. A notch is provided at the base of the sensor to ensure any condensate forming on the sensor itself does not collect at the sensor base. Further the interior of the housing is roughened and treated with an antifogging agent to ensure any condensate falls continuously so droplets do not form.Type: GrantFiled: January 25, 2002Date of Patent: May 16, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Malcolm David Smith, Peter John Leonard

Publication number: 20040079370Abstract: A flow probe for use in a humidification system is disclosed. The flow probe is adapted to be positioned in a humidified gases flow (for example oxygen or anaesthetic gases) such as that which is provided to a patient in a hospital environment. The flow probe is designed to provide both temperature and flow rate sensing of the gases flow by incorporating two sensors (preferably thermistors) and the shape and alignment of the probe enables accurate readings by reducing the occurrence of condensation on the sensors.Type: ApplicationFiled: October 23, 2003Publication date: April 29, 2004Applicant: Fisher & Paykel LimitedInventors: Lewis George Gradon, Stephen William McPhee, Paul John Seakins, Peter John Leonard
