Description

Sleep quality detection device

Technical Field

The present invention relates to a sleep detection device, and more particularly, to a device for detecting sleep quality at home.

Background

Obstructive Sleep Apnea (OSA) is a symptom in which muscles of the respiratory tract relax and collapse during Sleep, block the respiratory tract, and cause unsmooth breathing or Apnea. The patient can stop sleeping due to the apnea, so that the sleeping quality is poor, the daytime mental condition is affected, and serious traffic accidents are even caused. Currently, medical science has proved that if patients with OSA are not treated for a long time, cardiovascular burden is caused, and other problems such as hypertension, apoplexy, heart failure, arrhythmia, diabetes and the like are caused, so that the health influence caused by OSA is not ignored.

"sleep multiple physiology examination (PSG)" is a standard tool that is currently used in medical research for sleep, diagnosis of sleep physiology, sleep disorders, and sleep-related diseases. Conventional sleep multi-item physiological detection channels include electroencephalography (EEG), ophthalmography (EOG), Electromyography (EMG), Electrocardiogram (ECG), blood oxygen Saturation (SaO2 validation), Pulse (Pulse), oronasal respiratory Flow (Nasal-Oral Air Flow), thoracoabdominal respiratory effort (thoracoac addominal effort), and the like.

The sleep examination performed in the medical place at present may cause poor sleep quality at night or cause inaccurate examination report due to failure to fall asleep at all due to factors such as sleep environment replacement and examination line sticking. Therefore, it is a need to solve the problem of changing the sleep environment by sleep detection and still achieve the purpose of sleep detection. A typical PSG detects signals that record at least 12 channels and requires a minimum of 22 wires to attach to the patient's body, and the number of these detection channels can be adjusted to the needs of the sleep therapist. These connections are collected from the test channels recording the patient PSG signals in a cpu box, which is then connected to a computer system for recording, storing and displaying the test results. During sleep, the computer display may continuously display signals of multiple detected channels simultaneously. Based on the consideration of improving the sleeping comfort of the patient and the accuracy of the detection result and reducing the sleeping inspection cost, the sleep detection is developed at present, and the patient can detect the sleeping quality at home according to the indication of a sleep therapist and the detection tool for screening. The sleep detection tool mainly comprises a respiratory airflow detection device and a blood oxygen saturation concentration detection device. The patient can use the detection tools to automatically detect the sleep quality at home for one to several days, and then return the detection device to the sleep therapist, and then the sleep therapist accesses/analyzes the detection result from the detection device so as to further diagnose whether the patient has sleep disorder or disease. In addition, the PSG detecting device as known above needs to stick a plurality of connecting wires on the body of the patient, which causes inconvenience to the patient. The movement of the body of the patient during sleep may also cause some of the wires to fall off and fail sleep detection.

Detailed Description

Fig. 1 is a front perspective view of a sleep quality detection apparatus according to a first embodiment of the present invention, and fig. 2 is a rear perspective view of the sleep quality detection apparatus according to the first embodiment of the present invention. In the first embodiment, the sleep quality detection apparatus 100 of the present invention includes a respiratory airflow sensor 101 and a circuit board 102. The respiratory airflow sensor 101 is used for detecting the nasal respiratory airflow or the oral respiratory airflow of a user; the respiratory airflow detector 101 detects nasal respiratory airflow when the user's respiratory airflow is through the nasal cavity, but the respiratory airflow detector 101 detects oral respiratory airflow when the user, such as a nose block, changes his mouth to breathe and thus his respiratory airflow is through the oral cavity. The circuit board 102 is configured to process the detected respiratory airflow signal and store the respiratory airflow signal and the processing result. The respiratory airflow sensor 101 includes a sensor 1010, a first attachment member 1012 and a second attachment member 1013. The sensor 1010 is adapted to be attached between the nose and mouth of the user to capture the real-time respiratory airflow signal of the user, and two

airway tubes

1011a and 1011b are formed near the sensor 1010. The

air tubes

1011a and 1011b are adapted to be inserted into the nostrils of the user such that the nasal respiratory airflows communicate with the sensor 1010 through the

air tubes

1011a and 1011 b. When the user cannot breathe through the nose, such as when the nose is blocked and the user changes to mouth breathing to allow the user to flow through the mouth, the sensor 1010 detects the flow of breathing gas in the user's mouth. The first attachment part 1012 is attached to a cheek side of the user, and the circuit board 102 (not shown) and a power supply battery are accommodated in the first attachment part 1012 to serve as the power supply 103 of the sleep quality detection apparatus 100. The second attachment member 1013 is configured to be attached to the other side of the cheek of the user, and the second attachment member 1013 is provided with a switch 1014 for turning on/off the respiratory airflow sensor 101.

In a first embodiment, the respiratory airflow sensor 101 is secured to the user's face by the first attachment member 1012 and the second attachment member 1013. As shown in fig. 1 and 2, the sensor 1010, the first attachment member 1012, and the second attachment member 1013 are integrated into a single device. In other words, in the first embodiment, the respiratory airflow sensor 101 and the circuit board 102 are integrated into a single device, and all electrical connections are not exposed. Referring to fig. 3, the sleep quality detection apparatus 100 can prevent a plurality of electrical connection wires from being attached to the user's body in the use state, so as to improve the comfort and convenience of the user, avoid adverse effects on the sleep quality of the user, and improve the accuracy of the sleep detection result. Furthermore, the sleep quality detection apparatus 100 can prevent the electrical connection wire from falling off due to the user's action during the sleep detection without using an exposed electrical connection wire, thereby ensuring the normal operation of the sleep quality detection apparatus 100. In addition, the invention can avoid potential danger caused by winding of the electric connecting wire in sleep.

The signal conditioning unit 1020 is coupled to the sensor 1010 for amplifying the detected respiratory airflow signal and filtering unwanted noise. The signal collecting unit 1022 is used for converting the respiratory airflow signal into a digital signal. The processor unit 1024 is used for processing the digital signal and generating a respiratory flow resistance index. The storage unit 1026 is used for storing the digital signal and the respiratory flow resistance index. The communication interface unit 1028 is used for communication between the user and the outside, for example, an external communication system can access the stored data of the storage unit 1026 via the communication interface unit 1028, so that the sleep therapist can analyze the detected sleep data and perform sleep diagnosis.

Fig. 5 is a perspective view of a sleep quality detection apparatus according to a second embodiment of the present invention. In a second embodiment, the sleep quality detection apparatus 200 includes a respiratory airflow sensor 201 and a circuit board (not shown). The respiratory airflow sensor 201 is used for detecting the nasal respiratory airflow or the oral respiratory airflow of a user; the respiratory airflow sensor 201 detects nasal respiratory airflow when the user's respiratory airflow is through the nasal cavity, but the respiratory airflow sensor 201 detects oral respiratory airflow when the user, such as a nose block, changes to mouth breathing so that his respiratory airflow is through the oral cavity. The circuit board is used for processing the detected respiratory airflow signal and storing the respiratory airflow signal and a processing result. The respiratory airflow sensor 201 includes a sensor 202 and an ear-mount member 203. The ear-hook member 203 has a first end 2032 and a second end 2034. The sensor 202 is received at the first end 2032 of the ear-hang element 203 and is configured to be positioned between the mouth and nose of the user to capture the user's real-time respiratory airflow signal. Two

ventilation conduits

2033a and 2033b are formed near the sensor 202. The

airway tubes

2033a and 2033b are configured to be inserted into the user's nares to communicate the nasal flow of breathing gas to the sensor 202 through the

airway tubes

2033a and 2033 b. When the user cannot breathe through the nose, such as when the nose is blocked and the mouth is changed to breathe, the sensor 202 detects the flow of the user's breath. In some embodiments, the sensor 202 may be a thermistor sensor, a pressure sensor, an airflow sensor, a respiration rate sensor, or a combination thereof. The second end 2034 of the ear-hook component 203 houses the circuit board (not shown) and a power supply battery for supplying power to the sleeper quality detection apparatus 200. As shown in fig. 6A-6D, the ear-hook member 203 extends from the first end 2032 to the ear along a side contour of the user's face, such that the second end 2034 of the ear-hook member 203 is suspended against the ear to fix the respiratory airflow sensor 201 on the user's face. The second end 2034 of the ear-hook component 203 can further be provided with a switch 2036 for controlling the on/off of the sleep quality detection apparatus 200.

Fig. 7 is a perspective view of a sleep quality detection apparatus according to a third embodiment of the present invention. In a third embodiment, the sleep quality detection apparatus 300 includes a respiratory airflow sensor and a circuit board (not shown). The respiratory airflow sensor is used for detecting the nasal respiratory airflow or the oral respiratory airflow of a user; the respiratory airflow sensor detects nasal respiratory airflow when the user's respiratory airflow is through the nasal cavity, but detects oral respiratory airflow when the user, such as a nose block, changes to mouth breathing so that his respiratory airflow is through the oral cavity. The circuit board is used for processing the detected respiratory airflow signal and storing the respiratory airflow signal and a processing result. The respiratory airflow sensor is a nasal sensor 301 having a first side 302 and a second side 303, the first side 302 having a sensor 304 for capturing the instantaneous respiratory airflow signal of the nasal cavity of the user. However, when the user cannot breathe through the nose, such as when the nose is blocked, and instead breathes through the mouth, the sensor 304 detects the flow of breathing gas through the mouth of the user. The second side 303 accommodates the circuit board therein, and a switch 305 is disposed at the second side 303 for controlling the sleep quality detection apparatus 300 to be turned on or off. Referring to fig. 8, the nasal sensor 301 is used to clamp the nose of the user, so that the first side 302 and the second side 303 jointly clamp the nose, thereby fixing the sleep quality detection apparatus 300 on the nose. The sensor 304 and the circuit board of the third embodiment may adopt the implementation aspects of the first and second embodiments, and are not repeated here.

Referring to fig. 8, the respiratory airflow sensor 301 and the circuit board are integrated into a single device, all the electrical connection wires are not exposed, and the sleep quality detection apparatus 300 of the third embodiment also has many advantages of the sleep quality detection apparatuses of the first and second embodiments.

In a fourth embodiment, the sleep quality detection apparatus 400 includes a respiratory airflow sensor 401 and a circuit board (not shown). The respiratory airflow sensor 401 is used to detect the nasal respiratory airflow or the oral respiratory airflow of a user. The respiratory airflow sensor 401 detects nasal respiratory airflow when the user is breathing in the nasal cavity, but the respiratory airflow sensor 401 detects oral respiratory airflow when the user is breathing in the oral cavity, for example, when a nose blockage. The circuit board is used for processing the detected respiratory airflow signal and storing the respiratory airflow signal and a processing result.

right ear bands

4010 and 4012 are respectively attached to the left and right sides of the face of the user and extend to the rear of the left and right ears, so as to fix the sleep quality detection apparatus 400 on the face of the user. The circuit board (not shown) is housed inside the body 402. In addition, a battery holder (not shown) may be disposed inside the body 402 for accommodating a battery as a power supply. The sensor 403 is housed in the body 402 and is used to acquire the user's real-time respiratory airflow signal. The body 402 has a hollow chamber therein, and the nasal airflow of the user can be communicated with the sensor 403 through the hollow chamber, so that the sensor 403 can capture the real-time nasal airflow signal of the user. However, when the user, such as a nose block, changes to mouth breathing, the respiratory airflow sensor 403 detects the flow of mouth breathing air.
