Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a sleep oronasal breathing monitoring device. Background Art

[0002] Polysomnography is an important analytical tool for sleep medicine-related diseases. The oral and nasal airflow sensor is the main component of respiratory monitoring, and the collected relevant parameters are the main indicators for diagnosing and determining the severity of sleep-related breathing disorders.

[0003] The more common respiratory monitoring devices currently available basically use thermal sensors, which monitor the airflow of the patient's mouth and nose by obtaining the temperature difference between the patient's exhaled gas and the temperature of the surrounding air. This sensor has good sensitivity, but is not suitable for long-term use. In addition, since these respiratory monitoring devices mostly use the respiratory monitoring component by gluing wires, or by using plastic hoses at both ends to hang on the patient's ears for fixation, or directly inserting it into the patient's nasal cavity for respiratory monitoring, patients may easily feel uncomfortable when using it. In addition, since patients may turn over or move their heads during sleep, the wire connections or hoses may be damaged, causing the respiratory monitoring device to fall off, resulting in poor reliability. Summary of the Invention

[0004] In response to the above-mentioned problems, the present invention aims to provide a sleep oronasal breathing monitoring device. By designing an oronasal airflow monitoring component and placing a flexible thin-film integrated pressure and temperature sensor in the oronasal airflow monitoring component, the device can monitor the patient's oronasal breathing. The device has high monitoring sensitivity and accuracy. By designing a fixed base plate and elastic straps, the oronasal airflow monitoring component is mounted on the fixed base plate and tied to the patient's head or neck with the elastic straps, thereby fixing the entire device between the patient's mouth and nose, improving the stability of the device and the patient's comfort. The device has the advantages of high monitoring sensitivity, high monitoring accuracy, good stability, good comfort, and strong flexibility.

[0005] The main idea of ​​the technical solution adopted by the present invention is to design an oral and nasal airflow monitoring component, and perform oral and nasal breathing monitoring on the sleeping patient by installing flexible sensors in the oral monitoring port and the nasal monitoring port facing the patient's mouth and nasal cavity respectively. A fixed base plate and an elastic strap are designed, and the breathing detection component is installed on the fixed base plate and fixed to the position between the patient's mouth and nose by the strap to prevent the device from falling off due to the patient's body or head turning during sleep, thereby improving stability and comfort for patients when using it.

[0006] In order to achieve the above purpose, the technical solutions adopted by this utility model are as follows:

[0013] A strap mounting rod is provided on both sides of the fixed base plate, and the two ends of the elastic strap are inserted along the strap mounting rod. The bottom of the strap mounting rod is also provided with a limit block for preventing the elastic strap from falling off.

[0014] The beneficial effects of the utility model are:

[0015] 1. By designing an oral and nasal airflow monitoring component, a flexible film-type integrated pressure and temperature sensor is installed in the nasal monitoring port and the oral monitoring port to monitor the oral and nasal respiratory airflow of the patient during sleep. Compared with the existing monitoring device using a thermal sensor, the utility model has higher monitoring sensitivity and accuracy, and is suitable for long-term use.

[0016] 2.

Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0027] The inventors have found that the more common existing respiratory monitoring devices basically use thermal sensors to monitor the airflow of the patient's mouth and nose by obtaining the temperature difference between the patient's exhaled gas and the temperature of the surrounding air. This sensor has good sensitivity, but is not suitable for long-term use. In addition, since this type of respiratory monitoring device is mostly made by gluing the respiratory monitoring component, or by using plastic hoses at both ends to hang on the patient's ears for fixation, or directly inserting it into the patient's nasal cavity for respiratory monitoring, patients are prone to discomfort when using it. In addition, since the patient may turn over or move his head during sleep, the hose may be damaged, causing the respiratory monitoring device to fall off, and the reliability is poor.

[0028] Based on the above findings, the present application proposes a sleep oronasal breathing monitoring device, which monitors the patient's oronasal breathing by designing an oronasal airflow monitoring component and placing a flexible thin-film pressure-temperature integrated sensor in the oronasal airflow monitoring component. The monitoring has high sensitivity and accuracy. By designing a fixed substrate and an elastic strap, the oronasal airflow monitoring component is installed on the fixed substrate and tied to the patient's head or neck with an elastic strap, so that the entire device is fixed between the patient's mouth and nose, thereby improving the stability of the device and the patient's comfort. The device has the advantages of high monitoring sensitivity, high monitoring accuracy, good stability, good comfort and strong flexibility.

[0029] See Figure 1 as well as Figure 2 The present application discloses a sleep oronasal breathing monitoring device, including a fixed base plate 1.
