Abstract

A breathing assistance mask uses an air pump arrangement (e.g. fan or microchannel pump) is used for ventilating the mask volume. The mask distinguishes between a nasal breathing type and an oral breathing type, and the air pump arrangement is controlled accordingly to provide an appropriate flow location and / or direction. In this way, the operation of the mask is effective regardless of the typeof breathing of the user.

Description

technical field [0001] The present invention relates to respiratory masks. Background technique [0002] Air pollution is a worldwide concern. The World Health Organization (WHO) estimates that 4 million people die each year due to air pollution. Part of the problem is outdoor air quality in cities. Almost 300 cities hit by smog failed to meet national air quality standards. [0003] Official outdoor air quality standards define particulate matter concentrations as mass concentrations per unit volume (eg, μg / m 3 ). Of particular concern is the pollution with particles having a diameter of less than 2.5 μm (referred to as “PM2.5”) because particles with a diameter of less than 2.5 μm are able to penetrate (<100nm) can pass through the lungs to affect other organs. [0004] Since the problem does not improve significantly on short timescales, a common way of dealing with the problem is to wear a face mask that filters to provide cleaner air, and the market for face ma...
