Abstract
A moisture exchange fabric is disclosed the fabric comprising: a substrate fabric; a polymer having lower critical solution temperature (LCST) of between 25° C. and 39° C. bonded to the substrate fabric; and a filament sewed into the substrate fabric. Also disclosed is a humidifying apparatus using the moisture exchange fabric.
Claims20
A respiratory humidifying apparatus comprising:
- a moisture exchange fabric positioned so that a respiratory system inspiration and expiration airflow is in contact with the moisture exchange fabric, the moisture exchange fabric comprising:
- a substrate fabric, and
- a temperature-responsive polymer having lower critical solution temperature (LCST) of between 25° C. and 39° C. bonded to the substrate fabric;
- a heater for heating the moisture exchange fabric;
- a power supply for supplying power to the heater;
- and
- a controller controlling the supply of power to the heater such that during inspiration when the moisture exchange fabric is heated and moisture is added to the incoming air such that humid air is provided to a user and during expiration the moisture exchange fabric extracts moisture from the air.
A method of controlling the water vapour release and absorption of a moisture exchange fabric providing humidified air to a user positioned so that a respiratory system inspiration and expiration airflow is in contact with the moisture exchange fabric, the moisture exchange fabric comprising a substrate fabric and a temperature responsive polymer having a lower critical solution temperature (LCST) of between 25° C. and 39° C. bonded to the substrate fabric, the method comprising using a controller to control a heater by controlling the supply of power to the heater such that during inspiration the moisture exchange fabric is heated and moisture is added to incoming air such that humid air is provided to a user and during expiration the moisture exchange fabric extracts moisture from the air.
