Description

Technical Field

[0001] The utility model relates to the technical field of human body monitoring devices, in particular to an oral and nasal airflow collection device. Background Art

[0002] Respiration, as an activity of gas exchange between the human body and the outside world, its frequency and depth are basic physiological indicators reflecting the health status of the human body. Sleep disordered breathing is a disease in which symptoms of respiratory disorders such as apnea, shallow breathing or irregular breathing occur during sleep. With the increasing health problems and social negative impacts brought by sleep disordered breathing, the accurate diagnosis and personalized treatment of sleep disordered breathing deserve particular attention.

[0003] Existing oral and nasal airflow collection is usually carried out through a medical airflow collection tube. When in use, the airflow collection tube is placed under the nostrils of the subject to collect only the nasal airflow of the subject. The exhaled air from both nostrils is collected and connected to an airflow sensor for airflow analysis. However, in actual use, when the subject has nasal congestion or the habit of mouth breathing, a large amount of airflow signals will be lost, resulting in an increase in analysis error or even serious errors; at the same time, the comfort of the subject is poor when using the airflow tube collection method. Summary of the Utility Model

[0004] The purpose of the utility model is to overcome the problems of large errors caused by incomplete signal collection and poor comfort of the subject in the existing oral and nasal airflow collection device, and provide an oral and nasal airflow collection device.

[0009] Further, three thermocouples are provided, namely a first thermocouple, a second thermocouple and a third thermocouple; the first thermocouple and the second thermocouple are arranged in parallel on the upper edge of the collection main body; the third thermocouple is arranged in the middle of the lower edge of the collection main body.

[0010] Further, the middle part of the upper edge of the collection main body forms an arc-shaped part corresponding to the front part of the nasal tip towards the inside.

[0011] Further, collection wire harnesses are respectively arranged at both ends of the collection main body.

[0012] The beneficial effects of the present utility model are as follows: By using a thermocouple to replace the air flow tube for air flow collection and combining with a microphone to assist in collecting air flow data, accurate collection of oral and nasal air flow can be achieved. While improving the collection accuracy, the comfort level of the subject can be enhanced. BRIEF DESCRIPTION OF THE DRAWINGS

[0017] Embodiment 1

[0018] As Figure 1 shown, an oral and nasal air flow collection device includes a collection main body 1 with an internal circuit board. Specifically, the collection main body 1 internally contains a corresponding collection circuit board, which belongs to the prior art and will not be elaborated here. In order for the device to fit against the upper part of the lips, the middle part of the upper edge of the collection main body 1 forms an arc portion 16 towards the inside corresponding to the front part of the nasal tip.

[0019] A thermocouple, which is installed on the acquisition main body 1 and electrically connected to the circuit board. Specifically, three thermocouples are provided, namely a first thermocouple 11, a second thermocouple 12, and a third thermocouple 13. The first thermocouple 11 and the second thermocouple 12 are arranged in parallel on the upper edge of the acquisition main body 1. The third thermocouple 13 is arranged in the middle of the lower edge of the acquisition main body 1. Among them, the first thermocouple 11 and the second thermocouple 12 are used to measure the airflow data of two nostrils, and the third thermocouple 13 is used to measure the airflow data of the mouth. A thermocouple is a temperature sensor that uses the thermoelectric effect of two conductors made of different materials to measure temperature. The basic principle of a thermocouple is that two conductors made of different materials form a closed loop, and when there is a temperature difference at the two joints, there will be current flowing through the loop, and at this time, there is a thermal electromotive force (Seebeck effect) between the two ends. The analog-to-digital converter can convert the analog signal (voltage) into a digital signal, that is, convert the electromotive force generated by the thermocouple due to the airflow of the mouth and nose into a digital signal, which can then be displayed and processed by the upper computer. The data collected by the thermocouple is mainly the airflow of the mouth and nose, that is, the breathing airflow conditions of the mouth and nose parts, and corresponding signals are generated according to the size and heat of the airflow.

[0020] A sound pickup hole 15 with a built-in microphone, and the sound pickup hole 15 is located in the middle of the acquisition main body 1. The microphone is used to collect the nasal airflow data and snoring data of the subject. Further, in order to improve the sound pickup performance of the microphone, a diversion groove 14 is also provided on the surface of the acquisition main body 1. One end of the diversion groove 14 is located on the upper edge of the acquisition main body 1, and the other end is communicated with the sound pickup hole 15.

[0021] In order to facilitate the combined use of this device with the acquisition devices of other parts, acquisition wire harnesses 10 are respectively arranged at both ends of the acquisition main body 1.

[0022] By using a thermocouple to replace the air duct for airflow acquisition and combining a microphone to assist in collecting airflow data, the accurate acquisition of the airflow of the mouth and nose can be realized. While improving the acquisition accuracy, the comfort level of the subject can be improved.

[0023] The above embodiments only represent the specific implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several modifications and improvements can still be made, and these all belong to the protection scope of the present invention.
