Description

Sleep-disordered breathing screening equipment

The present invention relates to the screening of sleep-disordered breathing, in particular to a sleep-disordered breathing screening device.

Sleep apnea is a common sleep-disordered breathing that can be divided into obstructive type and central type. Obstructive type is more common, while central type is less common. Obstructive sleep apnea is a condition in which the soft tissue near the throat collapses due to tension relaxation during sleep, thereby compressing the upper airway, resulting in a temporary cessation of repeated breathing. Clinical manifestations include snoring, decreased blood oxygen levels, disrupted sleep, fatigue, and lethargy. Numerous clinical studies have also confirmed that sleep apnea is an important cause of hypertension, diabetes, gastric acid reflux, memory loss, and even glaucoma and retinopathy.

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

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 breathing pattern of the subject by observing the relevant data and graphs of the subject's blood oxygen saturation detected by the pulse oximeter.

Embodiments of the present invention will be described below with reference to FIGS. 1 to 5 . This description is not intended to limit the embodiments of the present invention, but is an example of the present invention.

As shown in FIG. 1 to FIG. 3, a sleep-disordered breathing screening apparatus 100 according to an embodiment of the present invention includes: a closing element 1, which is configured to cover the lips of the subject S and close Oral cavity; cheek incitement sensing member 2, comprising a plurality of sensing elements 21, a plurality of the sensing elements 21 are attached to the subject in a symmetrical manner and are respectively located on opposite sides of the closing element 1 The cheeks of S, wherein the cheek agitation sensing component 2 obtains the cheek agitation signal MBS of the subject S's cheeks, so as to sense whether the subject S has a problem caused by mouth breathing during sleep The action of pulsing the cheeks; the blood oxygen sensing component 3 is to sense 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 is electrically connected to the The cheek agitation sensing member 2 and the blood oxygen sensing member 3 receive the cheek agitation signal MBS from a plurality of the sensing elements 21 and the blood oxygen saturation signal OSS from the blood oxygen sensing member 3, and The signal processing component 4 performs signal processing SP on the waveform of the cheek pulsation signal MBS from the plurality of 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 a unit A cross-reference comparison is performed over time to generate a sleep-disordered breathing test result R for sleep-disordered breathing analysis A, wherein the sleep-disordered breathing analysis A is the waveform ratio of the signal processing result SPR to the blood oxygen saturation The curve of the degree signal OSS is obtained, and the number of mouth breathing performed by the subject S in the unit time and the control of the blood oxygen saturation OS are 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 can prevent the air from being directly exhaled from the oral cavity when the subject S performs mouth breathing. The cheek agitation signal MBS sensed by the cheek agitation sensing member 2 is too weak, which increases the difficulty of the sleep-disordered breathing screening apparatus 100 of the present invention to perform the sleep-disordered breathing analysis A. In other words, the closing element 1 helps the cheek pulsation sensing member 2 to sense the clear and obvious cheek pulsation signal MBS. Wherein, the cheek agitation signal MBS is presented in the form of a vibration waveform. The sealing element 1 is a breathable adhesive tape in this embodiment, and can also be any other object that can be used to close the oral cavity of the subject S without affecting the subject S to perform mouth breathing.

Specifically, a plurality of the sensing elements 21 are attached to the cheeks of the subject S in a symmetrical manner and are respectively located on two opposite sides of the closing element 1 . Wherein, a plurality of the sensing elements 21 with a symmetrical number means: if one side of the cheeks of the subject S is attached with one of the sensing elements 21, the other side of the cheeks must also be attached One of the sensing elements 21 is attached; if two of the sensing elements 21 are attached to one side of the cheeks, then two of the sensing elements 21 must also be attached to the other side of the cheeks , and so on.

In detail, although the cheek pulsation sensing member 2 mainly senses the cheek pulsation signal MBS formed by the subject S's mouth breathing to pulsate the cheeks, if the subject S also has the signal MBS during sleep When performing nasal breathing, the cheek agitation sensing member 2 can also sense the weak vibrations generated by the subject S performing nasal breathing, and the cheek agitation signal MBS may also include a tiny waveform, which is generally regarded as such a tiny waveform. Take it as a nasal breathing signal. On the other hand, the signal processing SP executed by the signal processing component 4 further includes a function of amplifying the amplitude of the received cheek pulsation signal MBS.

As shown in Fig. 2 to Fig. 5, when the cheek agitation sensing member 2 senses the movement of the subject S's cheeks pulsing due to mouth breathing during sleep, 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 sleep-disordered breathing analysis component 5 to perform the sleep-disordered breathing analysis A. Performing the signal processing SP can be regarded as a pre-operation of the sleep-disordered breathing analysis component 5 before performing the sleep-disordered breathing analysis A, the purpose is to enable the sleep-disordered breathing analysis component 5 to perform the sleep-disordered breathing analysis A in a better manner. The efficient way assists in confirming whether the subject S suffers from sleep apnea. The filtering F arithmetic processing included in the signal processing SP is to eliminate the noise existing in the cheek pulsation signal MBS that has not been processed; the waveform identification WR arithmetic processing is to identify each cause of the cheek pulsation signal MBS for the cheek pulsation signal MBS. The waveform formed by the subject S performing mouth breathing, so that the sleep-disordered breathing analysis component 5 can easily calculate the number of mouth-breathing performed by the subject S per unit time during the sleep-disordered breathing analysis A; the waveform is marked WM arithmetic processing is to mark each peak of the cheek agitation signal MBS, so that the sleep-disordered breathing analysis component 5 facilitates the calculation of the subject S's mouth breathing per unit time when performing the sleep-disordered breathing analysis A. frequency.

The first sensing element 21a and the second sensing element 21b are respectively disposed on the cheeks of the subject S, and are electrically connected to the signal processing member 4 .

As shown in FIG. 2 to FIG. 5 , according to the sleep-disordered breathing screening device 100 according to the embodiment of the present invention, the sensing element 21 is an accelerometer, and the cheek movement sensing member 2 measures the The cheek agitation signal MBS includes a signal vibrating along the X axis, a signal vibrating along the Y axis, and a signal vibrating along the Z axis, and the signal processing SP is the same side cheek of the subject S vibrating along the X axis. The waveforms of the signal, the signal vibrating along the Y-axis, and the signal vibrating along the Z-axis are integrated and summarized to obtain the signal processing result SPR with a time record and representing the number of times of cheek agitation of the subject S.

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

As shown in FIG. 2 to FIG. 5, the signal processing SP further includes an integrated and integrated 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 triaxial signals (X2, Y2, and Z2) from the second sensing element 21b are also integrated into a single integrated signal waveform named GS2, so that the sleep-disordered breathing analysis component 5 can perform The sleep-disordered breathing analysis A is convenient for judging the subject S's mouth breathing frequency, breathing pattern, and even sleep conditions such as side sleeping.

In detail, in this embodiment, the first sensing element 21a is attached to the left cheek of the subject S's cheeks, 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 a bilateral reverse signal (X , Y); and the bilateral in-direction signal (Z) representing the body displacement produced by normal breathing, wherein the bilateral in-direction 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 as GS1, and the three-axis signals (X2, Y2 and Z2) from the second sensing element 21b are also integrated into a single integrated signal waveform and named as GS2.

As shown in FIGS. 1 to 2 , according to the sleep-disordered breathing screening apparatus 100 according to the embodiment of the present invention, the blood oxygen sensing component 3 is a pulse oximeter.

In detail, the pulse oximeter can be a Fingertip, Wrist-worn, Tabletop, Handheld, or any other device capable of measuring the blood in any form. The pulse oximeter for oxygen saturation OS.

As shown in FIGS. 1 to 3, after the sleep-disordered breathing screening apparatus 100 is activated, the plurality of sensing elements 21 begin to sense the cheek pulsation signal MBS, and the blood oxygen sensing member 3 begins to sense the Blood oxygen saturation signal OSS. The cheek stirring signal MBS is then subjected to the signal processing SP through the signal processing means 4 . The signal processing SP is to perform the filtering F, the waveform identification WR, the waveform notation WM, and the integrated summation CI on the cheek pulsation signal MBS to obtain the signal processing result SPR. The signal processing component 4 then compares the signal processing result SPR and the blood oxygen saturation signal OSS measured by the blood oxygen sensing component 3 with each other, and generates sleep disordered breathing for sleep disordered breathing analysis A Screening Results R. The sleep apnea analysis component 5 then performs the sleep apnea analysis A according to the sleep apnea screening result R, so as to evaluate and confirm whether the subject S suffers from sleep apnea. If the result of the sleep-disordered breathing analysis A performed by the sleep-disordered breathing 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 positive , then it is recommended to perform the sleep multiple physiological examination PSG after this screening, that is, to confirm whether the subject S is indeed suffering from sleep apnea by a more comprehensive medical examination process.

According to the sleep-disordered breathing screening apparatus 100 according to the embodiment of the present invention, in the sleep-disordered breathing analysis component 5, the sleep-disordered breathing analysis A is based on the fact that the subject S performs every minute of sleep during the unit time. If the mouth breaths are less than or equal to a predetermined number of mouth breaths (for example, three times per minute or less), and the blood oxygen saturation OS falls within the predetermined blood oxygen saturation change range (for example, the range of 95~100%), the tested subject is confirmed. Subject S does not suffer from sleep apnea, and the sleep apnea analysis A is based on the fact that the subject S performs more than the predetermined number of mouth breaths per minute during sleep during the unit time (for example: thirteen times per minute and more than thirteen times) mouth breathing, and the blood oxygen saturation OS falls within the predetermined blood oxygen saturation change range (for example: the range of 95~100%), and confirms that the subject S does not suffer from sleep Apnea, the sleep-disordered breathing analysis A is based on the fact that, within the unit time, the subject S performs the predetermined number of mouth breaths per minute (for example: three to twelve times) during sleep, and the blood oxygen When the saturation OS is lower than the predetermined range of blood oxygen saturation (eg, lower than 90%), it is confirmed that the subject S suffers from sleep apnea.

In detail, the sleep-disordered breathing screening apparatus 100 of the present invention defines a plurality of breathing patterns that may occur during the sleep of the subject S, wherein the “maximum number of breaths” varies from person to person. , so the classification of the breathing pattern of the subject S is also different. The pre-steps for defining multiple such breathing patterns are: (1) The sleep-disordered breathing analysis component 5 finds out the part of the signal in the cheek agitation signal MBS that has a waveform of mouth breathing or a small waveform (ie, the waveform of nasal breathing) for 3 to 5 consecutive minutes, and calculates the part of the signal The average number of breaths, and the average number of breaths is defined as the "maximum number of breaths". (2) After subtracting a predetermined value (for example, subtracting three) from the calculated "maximum number of breaths", the obtained value will be regarded as the number of mouth breaths per minute, and depending on the number of mouth breaths, the The number of mouth breaths will be classified to represent multiple different breathing patterns for further analysis. Plural definitions of this breathing pattern are: (a) During the unit time, the subject S performs mouth breathing less than the predetermined number of mouth breaths per minute (for example: less than three times per minute, excluding three times) during sleep: the sleep-disordered breathing analysis component 5 will determine The breathing pattern of the unit time is Complete Nasal Breathing (CNB), the blood oxygen concentration at this time 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 respiratory interruptions (ODI) is low. (b) During the unit time, the subject S performs mouth breathing more than the predetermined number of mouth breaths per minute (for example: thirteen and more than thirteen times per minute) during sleep: the sleep-disordered breathing analysis component 5 The breathing pattern of the unit time will be determined as Complete Mouth Breathing (CMB), which is the 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 small. (c) During the unit time, the subject S performs mouth breathing of the predetermined number of mouth breaths per minute (for example: three to twelve times) during sleep: the sleep-disordered breathing analysis component 5 will determine 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 variation (eg: less than 90%), and the ODI is high. (d) In addition, if the absolute value of the waveform mark WM difference (G-sensor Diff.) of the two-axis signal waveforms (GS1 and GS2) obtained by the operation processing of the integrated and inductive CI of the cheek agitation signal MBS is greater than 3, the sleep-disordered breathing analysis component 5 will determine that this breathing pattern is side sleep breathing (SS). The side-sleeping mouth breathing refers to the mouth breathing performed by the subject S in the side-sleeping process. 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 pulsation signal When the MBS is not sensed by the other sensing element 21, and the absolute value of the difference (G-sensor Diff.) of the waveform mark WM of the two-axis signal waveforms (GS1 and GS2) is greater than three, the sleep The breathing disorder analysis component 5 will determine that the breathing pattern of the unit time is side sleeping mouth breathing.

Specifically, the sleep-disordered breathing screening apparatus 100 of the present invention determines the breathing pattern of the subject S per unit time and the proportion of the breathing pattern in the entire sleep period, and matches the blood oxygen The saturation OS is compared with each other to check the sleep status of the subject S during the entire sleep process, and then to determine whether the subject S suffers from sleep apnea for the purpose of screening.

With the technical means adopted in the present invention, the sleep-disordered breathing analysis component 5 (herein referred to as a sleep technician) can obtain more evaluations and determine that the subject S suffers from sleep disorders during the screening of sleep apnea. Reference basis for apnea or not. When the sleep technician performs sensing and estimation of the breathing pattern of the subject S during sleep, the blood oxygen saturation measured by the blood oxygen sensing component 3 corresponds to the blood oxygen saturation signal OSS. The OS is cross-referenced and compared with the number of mouth breathing per unit time corresponding to the signal processing result SPR measured by the sleep-disordered breathing screening apparatus 100 of the present invention, so as to make 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-disordered breathing screening result R.

In addition, among many methods of treating sleep apnea, wearing a continuous positive airway pressure (CPAP) is a common treatment method, and sleep technicians can also interpret the sleep apnea of the present invention by interpreting the The sleep-disordered breathing disorder screening result R generated by the disorder screening device 100 is used to evaluate whether the patient's treatment effect after wearing CPAP is good or not. 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-disordered breathing screening apparatus 100 of the present invention can detect whether the subject S has a movement of cheeks caused by mouth breathing during sleep, and when the subject S is due to When mouth breathing is performed to form the action of cheek agitation, 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-disordered breathing screening apparatus 100 of the present invention can also help the sleep technician to know what the tongue muscle strength of the subject S is.

The above descriptions and descriptions are only descriptions of preferred embodiments of the present invention. Those with ordinary knowledge in the art can make other modifications according to the scope of the patent application defined below and the above descriptions, but these modifications should still be It is within the scope of the right of the present invention for the inventive spirit of the present invention.
