Embodiment Construction

[0058] The invention provides a breathing cycle monitoring device. An apparatus is provided that includes a mask for covering a user's nose and / or mouth, a first temperature sensor, a second temperature sensor, and a controller. The mask has breathable mask walls that define the mask volume. In use, a microclimate exists inside the mask volume. The first temperature sensor is located inside the mask volume to enable it to detect a first temperature of the inhaled and exhaled air inside the microclimate. The second temperature sensor is located outside the mask wall, at or adjacent to the surface of the breathable mask wall, so that it can detect a second temperature of the same air outside the microclimate. A controller compares the first temperature and the second temperature across the ventilating mask wall and is adapted to calculate a temperature difference parameter from the first temperature and the second temperature. In doing so, the controller is able to determine ...

In doing so, the controller is able to determine the user's breathing cycle.

Description

technical field [0001] The invention relates to a breathing cycle monitoring device and a control method, in particular to a breathing cycle monitoring device including a temperature sensor. Background technique [0002] Air pollution is a worldwide concern. The World Health Organization (WHO) estimates that 4 million people die each year from air pollution. Part of the problem is outdoor air quality in cities. Nearly 300 cities hit by smog failed to meet national air quality standards. [0003] Official outdoor air quality standards define particulate matter concentration as mass concentration per unit volume (eg μg / m 3 ). Of particular concern is the pollution of particles with a diameter smaller than 2.5 μm (known as “PM2.5”) because of their ability to penetrate into the gas exchange regions of the lungs (alveoli), and very small particles (<100nm) Can pass through the lungs and affect other organs. [0004] Since the problem won't improve significantly in the s...
