Description

Sleep apnea screening equipment

This creation is related to the screening of sleep disordered breathing, especially a device for the screening of sleep disordered breathing.

Sleep apnea is a common type of sleep breathing disorder, which can be divided into obstructive and central types. The obstructive type is more common and the central type is less common. Obstructive sleep apnea is when the soft tissue near the throat collapses due to the relaxation of tension during the patient's sleep, which then compresses the upper respiratory tract, causing repetitive breathing to stop temporarily. Clinical manifestations include snoring, decreased blood oxygen concentration, interrupted sleep, fatigue and lethargy. Numerous clinical studies have confirmed that sleep apnea is an important cause of hypertension, diabetes, acid reflux, memory decline, and even glaucoma and retinopathy.

For the diagnosis of sleep apnea, the standard method is to use polysomnography (PSG). During the PSG process, the subject must sleep in the sleep examination room overnight, and the relevant sleep technician will assist in testing, collecting and recording multiple physiological signals during at least six hours of sleep. Since the PSG requires a lot of time and medical resources, under normal circumstances, a screening test is performed before the PSG is performed, and then based on the screening test results, it is determined whether the subject needs a PSG.

Generally speaking, the most important reference for screening to assess whether a subject suffers from sleep apnea is the subject’s blood oxygen saturation during sleep. During the screening process, the sleep technician mainly estimates the subject’s breathing pattern by observing the relevant data and graphs of the subject’s blood oxygen saturation sensed by the pulse oximeter. Then determine whether you suffer from sleep apnea. However, this judgment result is derived from the sleep technician's estimation of the breathing pattern of the subject.

The following describes the implementation of this creation based on Figures 1 to 5. This description is not intended to limit the implementation of this creation, but is a kind of embodiment of this creation.

As shown in Figs. 1 to 3, a sleep apnea screening device 100 according to an embodiment of the present creation includes: a sealing element 1, which is configured to cover the lips of the subject S and close Oral cavity; cheek agitation sensing member 2, including a plurality of sensing elements 21, a plurality of the sensing elements 21 are symmetrical in number and respectively located on the opposite sides of the closed element 1 and attached to the subject The cheeks of S, wherein the cheek agitation sensing component 2 obtains the cheek agitation signal MBS of the cheeks of the subject S to detect whether the subject S is caused by mouth breathing during sleep The action of bulging cheeks; the blood oxygen sensing component 3, which senses the blood oxygen saturation OS of the subject S during sleep to obtain the blood oxygen saturation signal OSS; and the signal processing component 4, which is electrically connected to the The cheek agitation sensing member 2 and the blood oxygen sensing member 3, and the cheek agitation signal MBS is received from a plurality of the sensing elements 21, and the blood oxygen saturation signal OSS is received from the blood oxygen sensing member 3, and The signal processing component 4 performs signal processing SP on the waveform of the cheek stirring signal MBS from a plurality of the sensing elements 21 to generate a signal processing result SPR, and according to the signal processing result SPR and the blood oxygen saturation signal OSS in the unit A cross-reference comparison over time to generate a sleep apnea screening result R for sleep apnea analysis A, where the sleep apnea analysis A compares the signal processing result SPR waveform to the blood oxygen saturation The curve of the degree signal OSS is obtained, and a comparison of the number of oral breaths performed by the subject S in the unit time and the blood oxygen saturation OS is obtained to confirm whether the subject S suffers from sleep apnea.

In detail, the closing element 1 is used to close the oral cavity of the subject S so that the cheek agitation sensing member 2 avoids direct exhalation of air from the oral cavity when the subject S is breathing through the mouth. The cheek agitation signal MBS sensed by the cheek agitation sensing component 2 is too weak, which increases the difficulty of the sleep-disordered breathing detection device 100 of the present invention when performing the sleep-disordered breathing analysis A. In other words, the closing element 1 helps the cheek movement sensing member 2 to detect the cheek movement signal MBS clearly and clearly. Among them, the cheek stirring signal MBS is presented in the form of vibration waveform. The closing element 1 is a breathable tape in this embodiment, and it can also be any other object that can be used to close the oral cavity of the subject S without affecting the subject S's mouth breathing.

In detail, a plurality of the sensing elements 21 are attached to the cheeks of the subject S in such a manner that they are symmetric in number and located on opposite sides of the sealing element 1. Wherein, a plurality of the sensing elements 21 in a symmetrical number means: if one of the sensing elements 21 is attached to one of the cheeks of the subject S, the other side of the cheeks must also be One of the sensing elements 21 is attached; if two of the sensing elements 21 are attached to one side of the cheeks, two of the sensing elements 21 must be attached to the other side of the cheeks , And so on.

In detail, although the cheek agitation sensing member 2 mainly senses the cheek agitation signal MBS formed by the subject S’s mouth breathing and cheeks agitation, but if the subject S is also sleeping during sleep During nasal breathing, the cheek agitation sensing member 2 can also sense the weak vibrations caused by the subject S’s nasal breathing, and the cheek agitation signal MBS may also include tiny waveforms, and such tiny waveforms are generally Treated as a nasal breathing signal. On the other hand, the signal processing SP performed by the signal processing component 4 further includes the function of amplifying the amplitude of the received cheek stirring signal MBS.

A schematic diagram of the signal processing result SPR obtained by the signal processing SP. As shown in Figures 2 to 5, because the cheek pulsation sensing member 2 senses the movement of cheek pulsation due to mouth breathing during sleep of the subject S, other vibrations that have no special significance It will also be sensed by the cheek agitation sensing component 2, so that the cheek agitation signal MBS that has not undergone the signal processing SP has noise, which is not conducive to the subsequent sleep breathing disorder analysis component 5 to perform the sleep breathing disorder analysis A. Performing the signal processing SP can be regarded as the pre-work of the sleep disordered breathing analysis component 5 before the sleep disordered breathing analysis A, and the purpose is to enable the sleep disordered breathing analysis component 5 to perform better sleep breathing disorder analysis A. An efficient way to assist in confirming whether the subject S suffers from sleep apnea. The signal processing SP includes the filtering F operation processing to eliminate the noise in the cheek stirring signal MBS that has not yet been processed; the waveform recognition WR operation processing is to identify each cause of the cheek stirring signal MBS The waveform formed by the oral breathing of the subject S, so that the sleep-disordered breathing analysis component 5 facilitates the calculation of the number of oral breaths per unit time of the subject S when performing the sleep-disordered breathing analysis A; the waveform remarks The WM calculation process is to mark each peak of the cheek stirring signal MBS, so that the sleep disordered breathing analysis component 5 facilitates the calculation of the oral breathing per unit time of the subject S when performing the sleep disordered breathing analysis A. frequency.

As shown in Figure 2, the sleep apnea screening device 100 according to the embodiment of the present creation further includes the sleep apnea analysis component 5, which is electrically connected to the signal processing component 4, and is screened according to the sleep apnea disorder Result R performs the sleep-disordered breathing analysis A.

In other embodiments, the sleep-disordered breathing analysis component 5 can also be other related personnel who can confirm whether the subject S has sleep apnea, such as a sleep technician, a physician, or a smart robot.

As shown in Figure 2, according to the sleep apnea screening device 100 according to the embodiment of the present creation, the cheek movement sensing member 2 includes a first sensing element 21a and a second sensing element 21b. The first sensing element 21 a and the second sensing element 21 b are respectively disposed on the cheeks of the subject S, and are electrically connected to the signal processing member 4.

As shown in Figures 2 to 5, in the sleep disordered breathing screening device 100 according to the embodiment of the present creation, the sensing element 21 is an acceleration sensor (accelerometer), which is measured by the cheek agitation sensing member 2 The cheek stirring signal MBS includes a signal that vibrates along the X axis, a signal that vibrates along the Y axis, and a signal that vibrates along the Z axis. The signal processing SP is to vibrate along the X axis of the cheek on the same side of the subject S. The waveforms of the signal, the signal vibrating along the Y axis, and the signal vibrating along the Z axis are integrated to obtain the signal processing result SPR with a time record and indicating the number of cheek agitation of the subject S.

In detail, as shown in FIGS. 2 to 4, the signal of the vibration along the X-axis of the side cheek where the first sensing element 21a senses is X1, and the signal of the vibration along the Y-axis is Y1 And the signal of vibration along the Z axis is Z1; the signal of vibration along the X axis where the second sensing element 21b senses the side cheek is X2, the signal of vibration along the Y axis is Y2, and the signal along Z The signal of shaft vibration is Z2.

As shown in Figures 2 to 5, the signal processing SP further includes integrated induction CI operation processing, which integrates the three-axis signals (X1, Y1, and Z1) from the first sensing element 21a into a single integrated signal The waveform is named GS1, and the three-axis signals (X2, Y2, and Z2) from the second sensing element 21b are integrated into a single integrated signal waveform and named GS2, so that the sleep-disordered breathing analysis component 5 performs The sleep-disordered breathing analysis A is convenient for judging the number of mouth breaths, breathing patterns, and even side sleeping status of the subject S.

In detail, in this embodiment, the first sensing element 21a is attached to the left cheek of the subject S, and the second sensing element 21b is attached to the subject S’s cheek. The right cheek of both cheeks. The signals of a total of six axes sensed by the first sensing element 21a and the second sensing element 21b can be divided into two types of signals according to the directionality, including the bilateral reverse signal (X , Y); and the bilateral co-directional signal (Z) representing the body displacement caused by normal breathing, in which the bilateral co-directional signal (Z) is a weak signal. Both of the above can capture continuous/discontinuous breathing signals, but in order to simplify the signals on both sides, the three-axis signals (X1, Y1, and Z1) from the first sensing element 21a are integrated into a single integrated signal waveform It is named GS1, and the three-axis signals (X2, Y2, and Z2) from the second sensing element 21b are integrated into a single integrated signal waveform and named GS2.

As shown in Figures 1 to 2, according to the sleep apnea screening device 100 of the embodiment of the present invention, the blood oxygen sensing component 3 is a pulse-type blood oxygen concentration device.

In detail, the pulse oximeter can be fingertip, wrist-worn, tabletop, handheld, or other types that can measure the blood in any form. The pulse-type blood oxygen concentration device for oxygen saturation OS.

As shown in Figures 1 to 3, after the sleep apnea screening device 100 is activated, a plurality of the sensing elements 21 begin to sense the cheek agitation signal MBS, and the blood oxygen sensing component 3 begins to sense the The blood oxygen saturation signal OSS. The cheek stirring signal MBS then performs the signal processing SP through the signal processing component 4. The signal processing SP performs the filtering F, the waveform identification WR, the waveform annotation WM, and the integrated induction CI on the cheek stirring signal MBS to obtain the signal processing result SPR. The signal processing component 4 then compares the signal processing result SPR with the blood oxygen saturation signal OSS measured by the blood oxygen sensing component 3 with a cross-reference comparison to generate a sleep disordered breathing for sleep disordered breathing analysis A Screening result R. The sleep apnea analysis component 5 then performs the sleep apnea analysis A according to the sleep apnea screening result R to evaluate and confirm whether the subject S suffers from sleep apnea. If the result of the sleep apnea analysis A performed by the sleep apnea analysis component 5 is negative, it means that the subject S does not suffer from sleep apnea, and then this screening is ended; if the result is affirmative , After the end of this screening, it is recommended to perform the PSG, which is a multiple physiological examination of sleep, that is, to confirm whether the subject S is indeed suffering from sleep apnea syndrome through a more comprehensive medical examination process.

According to the sleep apnea screening device 100 of the embodiment of the present invention, in the sleep apnea analysis component 5, the sleep apnea analysis A is based on that the subject S performs every minute of sleep during the unit time Mouth breaths below the predetermined number of mouth breaths (for example, three times per minute or less), and the blood oxygen saturation OS falls within the range of the predetermined blood oxygen saturation change (for example: 95-100% range), and confirm the test The person S does not suffer from sleep apnea. The sleep-disordered breathing analysis A is based on the fact that during the unit time, the subject S is sleeping more than the predetermined number of mouth breaths per minute (for example: 13 times per minute and 13 times or more) mouth breath, and the blood oxygen saturation OS falls within the predetermined blood oxygen saturation change range (for example: 95-100% range), and it is confirmed that the subject S does not suffer from sleep Apnea, the sleep-disordered breathing analysis A is based on the fact that the subject S performs the predetermined number of mouth breaths per minute (for example, three to twelve times) during sleep during the unit time, and the blood oxygen The saturation OS is lower than the predetermined range of blood oxygen saturation changes (for example, lower than 90%), which confirms that the subject S suffers from sleep apnea.

In detail, the sleep disordered breathing screening device 100 of this creation defines multiple breathing patterns that may appear during sleep of the subject S. Among them, the "maximum number of breaths" varies from person to person. Therefore, the breathing pattern classification of the subject S is also different. The prerequisite steps to define plural types of this breathing pattern are: (1) The sleep-disordered breathing analysis component 5 finds out the part of the signal with oral breathing waveform or tiny waveform (ie, the waveform of nasal breathing) in the cheek stirring signal MBS for 3 to 5 minutes, and calculates the part of the signal And define the average number of breaths as the "maximum number of breaths". (2) After subtracting a predetermined value (for example, subtracting three) from the calculated "maximum number of breaths", the resulting value will be regarded as the number of mouth breaths performed per minute, and depending on the number of mouth breaths, the The number of mouth breaths will be classified to represent a plurality of different breathing patterns for further analysis. The definitions of the plural types of breathing patterns are: (A) The subject S performs oral breathing less than the predetermined number of mouth breaths per minute (for example, less than three times per minute, excluding three) during the sleep process within the unit time: the sleep disordered breathing analysis component 5 will determine The breathing pattern per unit time is Complete Nasal Breathing (CNB). At this time, the blood oxygen concentration should be normal, and the blood oxygen saturation OS should fall within the range of the predetermined blood oxygen saturation change (for example: 95 ~100%), and the number of interruptions in breathing (ODI) is small. (B) In the unit time, the subject S performs oral breaths of more than the predetermined number of mouth breaths per minute (for example: thirteen times and more than thirteen times per minute) during the sleep process: the sleep disordered breathing analysis component 5 The breathing pattern per unit time will be judged to be Complete Mouth Breathing (CMB), which is a breathing pattern with obvious cheek agitation. At this time, the blood oxygen concentration should be normal, and the blood oxygen saturation OS should be It falls within the range of the predetermined blood oxygen saturation change (for example: 95~100%), and the ODI is low. (C) In the unit time, the subject S performs the predetermined number of mouth breaths (for example, three to twelve) mouth breaths per minute during the sleep process: the sleep disordered breathing analysis component 5 will determine the number of mouth breaths in the unit time The breathing pattern is Intermittent Mouth Breathing (IMB), which represents the symptoms of sleep apnea. At this time, the blood oxygen concentration will decrease, and the blood oxygen saturation OS should be lower than the predetermined blood oxygen saturation The range of change (for example: less than 90%), and there are many ODIs. (D) In addition, the absolute value of the difference between the two-axis signal waveforms (GS1 and GS2) of the two-axis signal waveforms (GS1 and GS2) of the cheek stirring signal MBS obtained by the integrated induction CI calculation process (G-sensor Diff.) If it is greater than three, the sleep-disordered breathing analysis component 5 will determine that this breathing pattern is side sleeping mouth breathing (SS). The side sleeping mouth breathing refers to the mouth breathing of the subject S while sleeping on his side during sleep. In detail, since the first sensing element 21a and the second sensing element 21b are respectively disposed on the cheeks of the subject S, when one of the sensing elements 21 senses the cheek agitation signal MBS but the other sensing element 21 fails to sense it, and the absolute value of the difference between the two-axis signal waveforms (GS1 and GS2) of the waveform note WM (G-sensor Diff.) is greater than three, then the sleep The breathing disorder analysis component 5 will determine that the breathing pattern per unit time is side-sleeping mouth breathing.

In detail, the sleep apnea screening device 100 of the present invention determines the breathing pattern of the subject S per unit time and the proportion of the breathing pattern during the entire sleep period, and matches the blood oxygen Saturation OS is cross-referenced for comparison to view the sleep status of the subject S during the entire sleep process, and then determine whether the subject S suffers from sleep apnea for the purpose of screening.

With the technical means used in this creation, the sleep apnea analysis component 5 (herein referred to as the sleep technician) can obtain more evaluations and determine that the subject S suffers from sleep during the screening of sleep apnea. Reference basis for respiratory arrest. When the sleep technician senses and estimates the breathing pattern of the subject S during sleep, the blood oxygen sensor 3 can measure the blood oxygen saturation corresponding to the blood oxygen saturation signal OSS OS is cross-referenced with the number of oral breaths per unit time measured by the sleep apnea screening device 100 corresponding to the signal processing result SPR, so that the breathing pattern of the subject S during sleep It can be presented in a more concrete way, and the sleep technician can also improve the objectivity and accuracy of the sleep apnea screening result R.

In addition, in the many methods of treatment of sleep apnea, wearing a continuous positive airway pressure (CPAP) is a common treatment method, and sleep technicians can also interpret the sleep breathing created by this book. The sleep apnea screening result R generated by the disorder screening device 100 is used to evaluate the treatment effect of the patient after wearing CPAP. During the treatment of sleep apnea, the sleep apnea screening device 100 can also be used to track the treatment effect. Furthermore, since the sleep apnea screening device 100 of the present invention can sense whether the subject S has an action that belongs to cheek agitation caused by mouth breathing during sleep, and when the subject S is due to When mouth breathing is performed to form the action of agitation of the cheeks, the meaning represented is: at this time, the base of the tongue of the subject S should be in a state of weakness. Therefore, the sleep breathing disorder screening device 100 of the present invention can also help the sleep technician understand the condition of the tongue muscle strength of the subject S.

The above descriptions and descriptions are only descriptions of the preferred embodiments of this creation. Those with ordinary knowledge of this technology should make other modifications based on the scope of patent application defined below and the above descriptions, but these modifications should still be made. It is the creative spirit of this creation and within the scope of the rights of this creation.
