Description

Technical Field

[0001] The utility model belongs to the field of medical detection, and particularly relates to a device and a detection method for oral and nasal dual-channel breathing monitoring based on the humidity principle. Background Art

[0002] Mouth breathing, the phenomenon of breathing mainly through the mouth during sleep at night, is usually rooted in upper airway obstruction, such as sinusitis, nasal polyps, hypertrophic nasal conchae, hypertrophic adenoids, hypertrophic tonsils and other factors. For children, if not properly treated, mouth breathing may lead to a series of facial problems, such as maxillary dysplasia, uneven teeth, loose lips, incomplete mouth closure, protruding upper front teeth, and narrow maxilla. In addition, for adults, mouth breathing problems are often accompanied by snoring, a noise during sleep caused by partial airway obstruction. The sound of snoring can be as high as 60dB or more, which interferes with the patient's rest and also affects normal gas exchange, which may cause serious problems, such as obstructive sleep apnea syndrome (OSAHS). OSAHS is a potentially fatal sleep breathing disorder associated with snoring, apnea and excessive daytime sleepiness during sleep. Nocturnal hypoxia and hypercapnia caused by apnea may cause serious complications such as hypertension, coronary heart disease, diabetes, cerebrovascular disease, and even sudden death at night. And whether it is children or adults, when they sleep through their mouths, they may suffer from problems such as dry mouth and foreign objects entering the mouth.

[0003] Mouth breathing has a significant adverse effect on sleep in both children and adults. However, it is quite difficult to self-check whether there is mouth breathing during sleep at night. There are a series of significant problems with the mouth breathing monitoring solutions currently on the market. Traditional mouth breathing monitoring devices usually require direct contact with the user's body, which may cause discomfort or unnecessary interference to the user during sleep, thereby affecting the quality and comfort of sleep. These devices include sensors that need to be worn on the face or mouth. This physical contact may cause discomfort to the user, such as pressure or inappropriate friction, thereby reducing the quality of sleep. Although there are some non-contact mouth breathing monitoring solutions, they are usually expensive, which greatly limits the use and promotion of users. In addition, these traditional monitoring devices usually require users to perform cumbersome data recording and processing. Users need to regularly record and analyze their mouth breathing data, which not only increases the user's workload, but also may reduce the accuracy of the data. This cumbersome process is very unfriendly to users who need to monitor mouth breathing for a long time.

[0004] In view of this, existing mouth-breathing monitoring solutions have challenges in many aspects, including comfort, user-friendliness, accuracy, intelligence and cost-effectiveness. In this case, the new mouth-breathing monitoring solution based on the principle of humidity is committed to overcoming these challenges, with an overall lightweight design, and can monitor the mouth-nasal breathing state during sleep without affecting the user's sleep state. The detection effect is more accurate and intuitive, providing a more comfortable, efficient and affordable mouth-nasal breathing monitoring experience. Utility Model Content

[0005] In order to solve the above problems, the utility model provides an oral and nasal breathing detection device and detection method based on the humidity principle. Since the exhaled gas contains moisture, according to the close relationship between breathing and humidity, the respiratory monitoring device of the utility model can use a humidity sensor to measure the humidity changes in the exhaled gas, thereby realizing the monitoring of the frequency, intensity and other related respiratory indicators of oral and nasal breathing. The device is lightweight and will not affect the user's sleep under normal circumstances. The detection effect is accurate and intuitive, and no additional data processing is required, which is convenient for self-testing at home.

[0006] To achieve the above-mentioned purpose, the technical solution adopted by the utility model is: a wearable oral and nasal respiratory monitor based on humidity principle, comprising a main body shell, a nasal passage humidity sensor and an oral passage humidity sensor, the main body shell is provided with a closed cavity and an open cavity, the closed cavity is provided with a battery and a circuit board, the circuit board comprises a data processing module and a wireless communication module, the nasal passage humidity sensor and the oral passage humidity sensor are connected to the data processing module, and the battery supplies power to the data processing module, the wireless communication module, the nasal passage humidity sensor and the oral passage humidity sensor; the nasal passage humidity sensor is provided in the upper half of the open cavity, and the oral passage humidity sensor is provided in the lower half of the open cavity; a baffle is provided between the oral passage and the nasal passage, one end of the baffle is connected to the main body shell, and the other end is suspended, and the shape of the suspended end can fit the outer part of the upper lip; a nose pad structure is provided on the upper part of the main body shell, and a flexible strap is connected to the nose pad structure.

[0014] Furthermore, the nose pad structure is made in combination with a 3D model of a human face.
