Description

Technical Field

[0001] The present invention relates to the technical field of sleep breathing detection, and more specifically, to an intelligent sleep breathing detection device and an application method thereof. Background Art

[0002] Sleep apnea-hypopnea syndrome (SAHS) is a serious sleep disorder that poses a major threat to the patient's quality of life and even life safety. In order to solve this problem, many devices based on various types of sensors (such as respiratory rate, heart rate, blood oxygen, etc.) are currently on the market. However, this type of device has a major drawback, which is that it is difficult to portability and is easy to get tangled due to turning over during use, affecting sleep. Chinese application, application number CN202310652204.2 provides a wireless sleep breathing monitor, which is attached to the lower part of the human nose in a manner similar to a nose patch, and uses wireless transmission to improve portability. Although this problem can be solved to a certain extent, this type of attachment still has a greater risk of falling off. Once it falls off, the monitoring effect is completely lost. At the same time, the vibrating plate is large in size and basically perpendicular to the angle of exhalation when the human body breathes. This will cause a large part of the exhaled gas to rebound when it contacts the vibrating plate, resulting in poor comfort in use. The most important thing is that this structure can only detect whether exhalation has occurred, but cannot detect inhalation, nor can it detect the specific intensity value of each breath. The existing detection of the specific value of breathing intensity still depends on the calculation of the algorithm, which is difficult to develop and the accuracy of the data is prone to errors. There is a need for a sleep breathing detection device and its application method that is not easy to fall off, has better comfort, and can specifically detect the intensity of each breath.

Each time when exhaling or inhaling is performed, the airflow generated will drive the longer end pin 60 of the detection piece 6 to deflect, and the shorter end pin 61 of the detection piece 6 will deflect accordingly and amplify the output torque according to the lever principle.
