摘要： 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.

摘要： Methods and apparatus for detecting apnoea that use ultrasonic sound waves are disclosed. The method consists of applying ultrasonic sound waves of varying frequency to a patient's airway and detecting their reflected sound waves. The sound waves are then analysed to determine whether there is a narrowing of the airway. In particular a transmitting ultrasonic transducer and receiving ultrasonic transducer are located on the interior surface of a mask and positioned so as to be directed towards the nares of the patient. A signal is emitted through the transmitting transducer and received at the receiving transducer. The received signal indicates a distance to a reflection or a distance to the narrowing of the upper respiratory tract. In this manner obstructions or narrowing of a patient's airway tract may be identified as reflections which appear at anatomically appropriate distances.

摘要： In one embodiment, there is provided a humidification chamber for use in a medical humidification system. The humidification chamber may comprise: a base and a top linked by a side wall to define the chamber, the chamber being configured to contain a volume of water; a gases inlet configured to receive a gases flow from a gases source; and a gases outlet, wherein the gases inlet is orientated relative to the side wall to introduce the gases flow to the humidification chamber at a direction substantially tangential to the side wall of the humidification chamber.

摘要： Abstract A connector is provided for coupling with an invasive patient interface for providing respiratory support to a patient. The connector comprises a connector body having: (i) an inlet port couplable with a flow source providing a flow of respiratory gas; (ii) a 5 gases exit port; and (iii) a device port couplable with the invasive patient interface. The connector also has a lumen having a first end and a second end. The connector body defines a gas flow path between the inlet port and both the device port and the lumen inlet and the lumen second end is disposed outside the device port. The lumen provides improved C02 clearance. Some embodiments provide for gas sampling 10 and/or variable expiratory resistance. m( 0( ((N (NN (NN (N CN r-C 0(NN CN (N (0
