AI Technical Summary
Existing wearable respiratory monitoring technologies struggle to achieve bidirectional integrated monitoring of inhalation and exhalation when wearing a mouth and nose mask. Furthermore, the sensor sensitivity is difficult to adjust, resulting in insufficient detection accuracy and comfort, and failing to meet the requirements of high sensitivity and low air resistance in various scenarios.
A bidirectional airflow sensing device with adjustable sensitivity was designed. By setting a baffle-type sensing component and an adjustment component inside the airflow duct of an oral-nose mask, the sensing sensitivity can be changed by adjusting the size of the baffle with a knob, realizing bidirectional integrated monitoring of inhalation and exhalation. The sensing sensitivity can also be controlled by adjusting the flow area inside the airflow duct by changing the size of the baffle.
It achieves bidirectional integrated monitoring of inhalation and exhalation under the condition of wearing a mouth and nose mask. The sensor sensitivity is adjustable, taking into account both detection accuracy and wearing comfort, and is suitable for continuous acquisition of respiratory parameters in multiple scenarios.
