An aerosol delivery system has a nebulizer and a humidifier providing a gas flow to the nebulizer. A controller varies humidity level of the gas flow to the nebulizer so that if the nebulizer is not operating it has about 100% humidity and it is operating the value is less to allow for the humidification effect of the nebulizer. The control may be achieved by dynamically varying proportions of flow through a dry branch and a humidification branch.

A gases humidification system includes a measuring chamber and a mixing chamber. The mixing chamber has one or more mixing elements that improve a mixing of gases before reaching the measuring chamber. Ultrasonic sensing is used to measure gases properties or characteristics within the measuring chamber. A baffle or a vane may be used to control and direct the gases flow through the mixing chamber as the gases flow moves into the measuring chamber.

A nasal ventilation mask having one or more attachment ports located adjacent to and overlying an upper lip of a patient when worn.

A high flow therapy system for delivering heated and humidified respiratory gas to an airway of a patient, the system including a respiratory gas flow pathway for delivering the respiratory gas to the airway of the patient by way of a non-sealing respiratory interface; wherein flow rate of the pressurized respiratory gas is controlled by a microprocessor.

The present invention relates to a tub configured to receive a volume of liquid for a humidifier, comprising at least one plastic component and at least one metal component, which together form a space for receiving said volume of liquid, wherein the at least one metal component and the at least one plastic component are attached to each other by means of a silicone seal. Furthermore, the invention relates to method for manufacturing a tub for a humidifier.

Several methods of supporting respiratory function of a patient before, during and/or after a medical procedure are disclosed. In certain arrangements, supporting respiratory function while a patient is under general anaesthesia can include providing a high gas flow that is greater than 15 L/min while the patient is under general anaesthesia. In certain arrangements, a method of providing ventilation while a patient is under general anaesthesia involves providing only a gas flow delivered through a nasal interface that is greater than 15 L/min while the patient is under general anaesthesia.

Assembly for dispensing a fluid product, having a nasal fluid product dispenser with a reservoir containing the fluid, a dispensing member, and a dispensing head on the dispensing member, the dispensing head provided with a dispensing orifice, a remote mobile device attached to the user's head, such as an earpiece, the nasal device and the remote mobile device attached to the user's head each having an orientation sensor, such as an accelerometer or a gyroscope. The orientation sensors cooperate to determine the position of the nasal dispenser in the nostril. The nasal dispenser has an indicator visible when the dispenser is in the nostril, to guide the user towards an optimal orientation of the nasal dispenser in the nostril. The nasal dispenser having an electronic module and automatic actuation mechanism that automatically actuates the nasal device when the orientation sensors detect that the nasal dispenser is arranged in an optimal position.

A device for nasal delivery of fluid product, having a reservoir containing a fluid, a delivery member, and a delivery head on the delivery member, and the delivery head provided with a delivery opening. The nasal device has a camera for determining the spatial positioning of the nasal device inside a nostril, the camera determining the vertical tilt angle and the lateral tilt angle between the longitudinal axis of the nasal device and an axis of the face identified by a plurality of reference points, the orientation of the axis with respect to the nostril identical to whatever the position of the user, a positioning indicator for guiding the user towards an optimal orientation of the nasal device inside the nostril, and an electronic module and automatic actuation mechanism for automatically actuating the nasal device when the camera determines that the nasal device is disposed in an optimal position.

In one embodiment, there is provided an inlet for a humidification chamber for use in a medical humidification system, the inlet comprising an inlet end configured to receive gases flow from a gases source, an outlet end configured to introduce the gases flow to the inside of the humidification chamber, and at least one wall defining, at least in part, a passageway between the inlet end and the outlet end for conveying gases therebetween. The outlet end of the inlet is configured to terminate in the humidification chamber or at a wall of the humidification chamber, and the passageway is configured to guide the gases flow such that the center of the gases flow at the inlet end and at the outlet end are substantially aligned along a common axis or the outlet end defines a profile of the passageway thereat that has a width and a height, a ratio of the width to height being between about 1:20 and 1:5.

A respiratory assistance system can include a humidifier used for delivery of heated and humidified gases to a patient includes a humidification chamber with an inlet and associated sensor, an associated heater and sensor, an inspiratory conduit with an associated heater and sensor, and an unheated patient interface, such as a face mask. A humidifier can include a control system configured to change a humidification chamber outlet temperature set point or an amount of generated humidity, including for example, a maximum outlet temperature set point, as a function of inlet gas temperature. The control system can reduce and/or minimize rainout (i.e. condensate) while maintaining a substantially consistent humidity in the gases delivered to a patient.
