Publication number: 20190030276Abstract: 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 determines the flow rate of the gases and then determines the required power input to the humidifier to deliver the gases to the patient at the required patient humidity. This means the need for external sensors is dispensed with and thus the apparatus is simple and less bulky.Type: ApplicationFiled: June 18, 2018Publication date: January 31, 2019Inventors: Peter John Hunt, Mohammad Thudor, David Fraser Wixey, Stephen William McPhee

Patent number: 10130787Abstract: 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.Type: GrantFiled: November 16, 2015Date of Patent: November 20, 2018Assignee: Fisher & Paykel Healthcare LimitedInventors: Peter John Hunt, Mohammad Thudor, David Fraser Wixey, Stephen William McPhee

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: 7106955Abstract: 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 determines the flow rate of the gases and then determines the required power input to the humidifier to deliver the gases to the patient at the required patient humidity. This means the need for external sensors is dispensed with and thus the apparatus is simple and less bulky. The resistance of the conduit heater element is monitored to give a coarse indication of flow rate.Type: GrantFiled: October 19, 2001Date of Patent: September 12, 2006Assignee: Fisher & Paykel Healthcare LimitedInventors: Mohammad Thudor, Stephen William McPhee

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
