Description
本發明係有關於一種呼吸肌訓練系統及方法，其尤指一種負壓式呼吸肌訓練系統及方法。 The present invention relates to a respiratory muscle training system and method, and more particularly to a negative pressure breathing muscle training system and method.
隨著科技的發展與繁榮、人類居住環境及飲食習慣的改變，目前許多國人有運動不足與飲食熱量過高的問題，使得容易會有心血管方面的疾病，以致需進行呼吸手術及心血管手術等外科手術的比率有逐年增加的趨勢，當患者進行呼吸或心血管手術時會進行麻醉，其中在經過麻醉後，肺部功能會受影響，使得在術後會有肺部塌陷的情況，就算不至於患病，人年紀過大後，呼吸肌與肺部組織的彈性降低，肺活量下降，亦會影響到肺的換氣功能。此外，有研究指出，肺活量大的人大多壽命會比肺活量小的人要長，因此，如何訓練呼吸肌以增加肺活量為極重要的課題。 With the development and prosperity of science and technology, changes in human living environment and eating habits, many people in China currently have problems of insufficient exercise and high calorie diet, which makes it easy to have cardiovascular diseases, which require respiratory surgery and cardiovascular surgery. The rate of surgery has increased year by year. When patients undergo respiratory or cardiovascular surgery, anesthesia will be performed. After anesthesia, lung function will be affected, so that there will be lung collapse after surgery, even if it is not As for the disease, when the person is too old, the elasticity of the respiratory muscles and the lung tissue is reduced, and the vital capacity is decreased, which also affects the ventilation function of the lungs. In addition, studies have shown that people with large lung capacity will live longer than those with small lung capacity. Therefore, how to train respiratory muscles to increase lung capacity is a very important issue.
此外，呼吸肌力量不足也會提升患者在睡眠時發生睡眠呼吸中止症的機率，睡眠呼吸中止症分為阻塞性睡眠呼吸中止症(Obstructive Sleep Apnea Syndrome，OSAS)、中樞神經性睡眠呼吸中止症(Central Sleep Apnea syndrome，CSAS)以及混和性睡眠呼吸中止症(Mixed Sleep Apnea Syndrome，MSAS)，其中，阻塞性睡眠呼吸中止症指的是，在睡眠中因呼吸道阻塞導致間歇性的呼吸中止，其必須符合每小時有5次以上的呼吸中止， 而且每次中止的時間須超過10秒。且嚴重的睡眠呼吸中止症會增加罹患心臟血管疾病的機率，比如高血壓、心律不整、心肌梗塞、腦中風等。而當長期睡眠品質不佳時，由於內分泌失調，糖尿病及肥胖症的比率亦會增加。除此之外，由於精神不好，病患發生車禍和工作受傷的機會亦遠超過一般人。 In addition, lack of respiratory muscle strength will increase the probability of sleep apnea in sleep. Sleep apnea is divided into Obstructive Sleep Apnea Syndrome (OSAS), central nervous sleep apnea ( Central Sleep Apnea syndrome (CSAS) and Mixed Sleep Apnea Syndrome (MSAS), in which obstructive sleep apnea refers to intermittent respiratory arrest due to airway obstruction during sleep, which must Meets more than 5 breath stops per hour, And each time the suspension must be more than 10 seconds. And severe sleep apnea will increase the risk of cardiovascular disease, such as high blood pressure, arrhythmia, myocardial infarction, stroke and so on. When the quality of long-term sleep is poor, the rate of diabetes and obesity will also increase due to endocrine disorders. In addition, due to poor mental health, patients have more opportunities for car accidents and work injuries than the average person.
由上述可知，呼吸肌的鍛鍊與人的健康方面是息息相關的，若增加呼吸肌的肌肉強度，除了可治療阻塞性睡眠呼吸中止症之外，亦可改善人整體的健康狀況。 It can be seen from the above that the exercise of the respiratory muscle is closely related to the health of the human being. If the muscle strength of the respiratory muscle is increased, in addition to treating obstructive sleep apnea, the overall health of the person can be improved.
其中，以治療阻塞性睡眠呼吸中止症為例，過去針對阻塞性睡眠呼吸中止症病患的非手術治療方式有：持續性氣道正壓(Continuous Positive Airway Pressure，CPAP)呼吸器治療，其為在睡眠時於人體鼻部戴一面罩，並連續正壓氣體經由鼻腔進入喉部及氣管，形同一個支撐架，避免睡眠中的呼吸阻塞；口內裝置，其為利用各種不同型式的口腔矯正器，將下顎及舌頭拉向前方，以此擴大呼吸道來減少呼吸阻塞。上述對於阻塞性睡眠中止症的治療方式並無法針對患者本身做治療，換句話說，上述治療方式是治標，並無法治本，當不使用氣道正壓呼吸器或口內裝置時，患者一樣會有睡眠呼吸中止症狀發生。 Among them, in the treatment of obstructive sleep apnea, for example, the non-surgical treatment for patients with obstructive sleep apnea is: continuous positive airway pressure (CPAP) respirator treatment, which is Wearing a mask on the nose of the human body during sleep, and continuous positive pressure gas enters the throat and trachea through the nasal cavity, forming a support frame to avoid respiratory obstruction during sleep; intraoral device, which utilizes various types of oral appliances Pull the chin and tongue forward to expand the airway to reduce breathing blockage. The above-mentioned treatment for obstructive sleep-stopping is not able to treat the patient itself. In other words, the above treatment is a palliative treatment, and there is no rule of law. When the positive airway respirator or intraoral device is not used, the patient will have the same Sleep breathing discontinuation symptoms occur.

為使 貴審查委員對本發明之特徵及所達成之功效有更進一步之瞭解與認識，謹佐以較佳之實施例及配合詳細之說明，說明如後：首先，請一併參閱第1A圖與第1B圖，第1A圖為本發明之第一實施例之呼吸肌訓練系統的方塊圖，而第1B圖為本發明之第一實施例之呼吸肌訓練系統與人體連接的示意圖。如圖所示，本發明之呼吸肌訓練系統10包含一負壓產生單元101與一回授電路102。負壓產生單元101連接至少一密封件1011，密封件1011貼附於一人體30之面部，以密封人體30之口部與鼻部而防止人體30之呼吸氣流漏出，也就是避免密封件1011之密封空間內的氣體漏出，而該負壓產生單元101用以產生一負壓氣流NP，並經由密封件1011將負壓氣流NP施加至人體30之呼吸道(口腔呼吸道與鼻腔呼吸道)。回授電路102用於量測人體30之呼吸狀態，並依據一參考訊號REF與人體30之呼吸狀態產生一控制訊號CON，且傳送控制訊號CON至負壓產生單元101，以控制負壓產生單元101停止提供負壓氣流NP至人體30之呼吸道(口腔呼吸道與鼻腔呼吸道)。 In order to give you a better understanding and understanding of the features and the efficacies of the present invention, please refer to the preferred embodiment and the detailed description for the following: First, please refer to Figure 1A and 1B, FIG. 1A is a block diagram of a respiratory muscle training system according to a first embodiment of the present invention, and FIG. 1B is a schematic view showing a respiratory muscle training system according to a first embodiment of the present invention connected to a human body. As shown, the respiratory muscle training system 10 of the present invention includes a negative pressure generating unit 101 and a feedback circuit 102. The negative pressure generating unit 101 is connected to at least one sealing member 1011. The sealing member 1011 is attached to the face of a human body 30 to seal the mouth and the nose of the human body 30 to prevent leakage of the breathing airflow of the human body 30, that is, to avoid the sealing member 1011. The gas in the sealed space leaks out, and the negative pressure generating unit 101 is used to generate a negative pressure airflow NP, and the negative pressure airflow NP is applied to the respiratory tract of the human body 30 (the oral respiratory tract and the nasal respiratory tract) via the sealing member 1011. The feedback circuit 102 is configured to measure the breathing state of the human body 30, generate a control signal CON according to a reference signal REF and the breathing state of the human body 30, and transmit the control signal CON to the negative pressure generating unit 101 to control the negative pressure generating unit. 101 stops supplying the negative pressure airflow NP to the respiratory tract of the human body 30 (oral and nasal respiratory tract).
此外，負壓產生單元101與密封件1011之間，更可連接一氣流導管1013，而負壓產生單元101透過氣流導管1013與密封件1011將負壓氣流NP施加至人體30之呼吸道(口腔呼吸道與鼻腔呼吸道)。 In addition, between the negative pressure generating unit 101 and the sealing member 1011, a gas flow conduit 1013 is further connected, and the negative pressure generating unit 101 applies a negative pressure airflow NP to the respiratory tract of the human body 30 through the airflow conduit 1013 and the sealing member 1011 (oral respiratory tract) With nasal respiratory tract).
回授電路102包含一呼吸量測模組103與一運算單元104。呼 吸量測模組103用於量測人體30之呼吸狀態，而依據人體30之呼吸狀態產生一回授訊號FB。運算單元104耦接呼吸量測模組103，並比較回授訊號FB與參考訊號REF，而依據回授訊號FB與參考訊號REF間的差異值產生控制訊號CON。 The feedback circuit 102 includes a respiratory measurement module 103 and an arithmetic unit 104. call The snubber module 103 is configured to measure the breathing state of the human body 30, and generate a feedback signal FB according to the breathing state of the human body 30. The computing unit 104 is coupled to the respiratory measurement module 103 and compares the feedback signal FB with the reference signal REF, and generates the control signal CON according to the difference between the feedback signal FB and the reference signal REF.
當呼吸量測模組103量測人體30之呼吸狀態為正常時，呼吸量測模組103輸出此時的回授訊號FB至運算單元104，經運算單元104比較參考訊號REF與回授訊號FB後，由於此時參考訊號REF小於回授訊號FB，也就是回授訊號FB所代表之人體30的吸氣氣流大於參考訊號REF所代表的門檻值，因此運算單元104輸出對應呼吸正常時之控制訊號CON，且此時負壓產生單元101依據控制訊號CON而施加負壓氣流NP至人體30，以作為人體30吸氣時之阻力，進而訓練人體30之呼吸肌。 When the respiratory measurement module 103 measures the breathing state of the human body 30 to be normal, the respiratory measurement module 103 outputs the feedback signal FB at this time to the operation unit 104, and compares the reference signal REF and the feedback signal FB via the operation unit 104. After that, since the reference signal REF is smaller than the feedback signal FB, that is, the inspiratory airflow of the human body 30 represented by the feedback signal FB is greater than the threshold value represented by the reference signal REF, the operation unit 104 outputs the control corresponding to the normal breathing. The signal CON, and at this time, the negative pressure generating unit 101 applies the negative pressure airflow NP to the human body 30 according to the control signal CON as the resistance when the human body 30 inhales, thereby training the respiratory muscles of the human body 30.
當呼吸量測模組103量測人體30之呼吸狀態為異常(呼吸中止)時，呼吸量測模組103輸出此時的回授訊號FB至運算單元104，並經運算單元104比較參考訊號REF與回授訊號FB後，由於此時參考訊號REF大於或等於回授訊號FB，也就是回授訊號FB所代表之人體30的吸氣氣流小於或等於參考訊號REF所代表的門檻值，因此運算單元104輸出對應呼吸異常時之控制訊號CON，負壓產生單元101依據控制訊號CON而停止產生負壓氣流NP至人體30，以防止人體30在訓練過程中發生危險。由上述可知，運算單元104是以參考訊號REF與回授訊號FB間之差異，作為判斷人體30之呼吸狀態的依據。 When the respiratory measurement module 103 measures that the breathing state of the human body 30 is abnormal (breathing is aborted), the respiratory measurement module 103 outputs the feedback signal FB at this time to the operation unit 104, and compares the reference signal REF via the operation unit 104. After the feedback signal FB is used, since the reference signal REF is greater than or equal to the feedback signal FB, that is, the inspiratory airflow of the human body 30 represented by the feedback signal FB is less than or equal to the threshold value represented by the reference signal REF, The unit 104 outputs a control signal CON corresponding to the abnormal breathing, and the negative pressure generating unit 101 stops generating the negative pressure airflow NP to the human body 30 according to the control signal CON to prevent the human body 30 from being dangerous during the training. As can be seen from the above, the arithmetic unit 104 uses the difference between the reference signal REF and the feedback signal FB as a basis for determining the breathing state of the human body 30.
其中，參考訊號REF是用於判斷人體30之呼吸狀態為正常或異常之門檻值，亦可依使用者所需調整參考訊號REF之值，例如 ，可將參考訊號REF調高，使得當人體30有吸氣氣流，但吸氣氣流過小時，即判斷為呼吸狀態異常。 The reference signal REF is used to determine the threshold value of the breathing state of the human body 30 as normal or abnormal, and may also adjust the value of the reference signal REF according to the user's needs, for example, The reference signal REF can be adjusted to be high, so that when the human body 30 has an inspiratory airflow, but the inspiratory airflow is too small, it is determined that the breathing state is abnormal.
此外，負壓產生單元101依據控制訊號CON且經一段時間後才會停止產生負壓氣流NP，此時間是用以判斷人體30之呼吸狀態是否確實為異常，例如將此時間設定為3秒，而運算單元104持續3秒傳送呼吸異常之控制訊號CON至負壓產生單元101時，負壓產生單元101才判斷人體30為呼吸異常，而停止產生負壓氣流NP，此動作亦可由運算單元104來做，例如運算單元104接收的參考訊號REF大於或等於回授訊號FB 3秒，則運算單元104才輸出對應呼吸異常的控制訊號CON，而負壓產生單元101依據此控制訊號CON停止產生負壓氣流NP。 In addition, the negative pressure generating unit 101 stops generating the negative pressure airflow NP according to the control signal CON, and the time is used to determine whether the breathing state of the human body 30 is indeed abnormal, for example, setting the time to 3 seconds. When the operation unit 104 transmits the control signal CON of the abnormal breathing to the negative pressure generating unit 101 for 3 seconds, the negative pressure generating unit 101 determines that the human body 30 is breathing abnormally, and stops generating the negative pressure airflow NP. This operation may also be performed by the arithmetic unit 104. For example, the operation unit 104 outputs the control signal CON corresponding to the breathing abnormality, and the negative pressure generating unit 101 stops generating the negative according to the control signal CON. Pressurized gas flow NP.
於此實施例中，呼吸量測模組103包含一氣流量測單元105，氣流量測單元105為一氣流流量計且連接於密封件1011，而藉由感測由呼吸肌訓練系統10流至人體30之口腔呼吸道與鼻腔呼吸道之氣流流量，而得知人體30之呼吸狀態是否為正常，當人體30之呼吸狀態為正常，也就是人體30有吸氣氣流時，氣流量測單元105感測到有氣流由呼吸肌訓練系統10流至人體30之口腔呼吸道與鼻腔呼吸道，而當人體30之呼吸狀態為異常，也就是人體30因本身呼吸肌力量不足，無法承受此時負壓產生單元101所施加的負壓氣流NP時，氣流量測單元105無法感測到無氣流由呼吸肌訓練系統10流至人體30之口腔呼吸道與鼻腔呼吸道，因此氣流量測單元105所量測到的兩種情形氣流有所差異，而產生對應的回授訊號FB。 In this embodiment, the spirometry module 103 includes a gas flow measuring unit 105. The gas flow measuring unit 105 is an air flow meter and is connected to the sealing member 1011, and is flown by the respiratory muscle training system 10 by sensing. The airflow of the oral cavity and the nasal airway of the human body 30, and it is known whether the breathing state of the human body 30 is normal. When the breathing state of the human body 30 is normal, that is, when the human body 30 has an inspiratory airflow, the gas flow measuring unit 105 senses When the airflow flows from the respiratory muscle training system 10 to the oral airway and the nasal respiratory tract of the human body 30, and when the breathing state of the human body 30 is abnormal, that is, the human body 30 is unable to withstand the negative pressure generating unit 101 due to insufficient respiratory muscle strength. When the negative pressure airflow NP is applied, the airflow measuring unit 105 cannot sense that no airflow flows from the respiratory muscle training system 10 to the oral airway and the nasal airway of the human body 30, and thus the two measured by the airflow measuring unit 105 The situation airflow is different, and a corresponding feedback signal FB is generated.
其中，如第1B圖所示，本實施例是將負壓產生單元101與運 算單元104設置於一呼吸肌訓練裝置100中，並連接呼吸肌訓練裝置100外之密封件1011、氣流導管1013與氣流量測單元105，但此設置方式並非用於限制本發明。 Wherein, as shown in FIG. 1B, in this embodiment, the negative pressure generating unit 101 is transported. The calculation unit 104 is disposed in a respiratory muscle training device 100, and is connected to the sealing member 1011 outside the respiratory muscle training device 100, the airflow conduit 1013, and the gas flow measuring unit 105. However, this arrangement is not intended to limit the present invention.
另外，本發明之呼吸肌訓練系統10亦可包含一輸入介面，而依據一使用者所輸入的選擇訊號，而控制負壓產生單元101，以選擇負壓產生單元101所產生之負壓氣流NP的壓力。 In addition, the respiratory muscle training system 10 of the present invention may further include an input interface, and the negative pressure generating unit 101 is controlled according to a selection signal input by a user to select the negative pressure airflow NP generated by the negative pressure generating unit 101. pressure.
請一併參閱第1C圖，其係為本發明之第一實施例之呼吸肌訓練系統與人體連接的狀態示意圖。如圖所示，密封件1011為一口鼻式面罩，其設置且密合於該人體30之口部與鼻部外側，以防止人體30之呼吸氣流漏出。呼吸肌訓練系統經由氣流導管1013與密封件1011而將負壓氣流NP施加於人體30之呼吸道(口腔呼吸道301與鼻腔呼吸道303)，而負壓氣流NP是由負壓產生單元101產生與人體30吸氣氣流方向相反之一氣流，以作為人體30吸氣時之阻力，進而達到鍛鍊人體30之呼吸肌的目的。 Please refer to FIG. 1C, which is a schematic diagram of a state in which the respiratory muscle training system of the first embodiment of the present invention is connected to a human body. As shown in the figure, the sealing member 1011 is a one-nose mask that is disposed and adhered to the outside of the mouth and the nose of the human body 30 to prevent leakage of the breathing airflow of the human body 30. The respiratory muscle training system applies a negative pressure airflow NP to the respiratory tract of the human body 30 (the oral respiratory tract 301 and the nasal respiratory tract 303) via the airflow conduit 1013 and the sealing member 1011, and the negative pressure airflow NP is generated by the negative pressure generating unit 101 and the human body 30. The airflow in the opposite direction of the inhalation airflow serves as the resistance of the human body 30 when inhaling, thereby achieving the purpose of exercising the respiratory muscles of the human body 30.
當呼吸肌訓練系統10開啟時，先進入一系統鑑別階段，呼吸肌訓練系統10之負壓產生單元101產生負壓氣流NP，並經由氣流導管1013與密封件1011而將負壓氣流NP施加於人體30之口腔呼吸道301與鼻腔呼吸道303，且逐漸提升負壓氣流NP之壓力，也就是逐漸提升負壓產生單元101抽出之氣體流量，直到人體30無法吸入氣體時，並將此時負壓氣流NP的壓力大小定義為人體30的最大肌肉強度(Maximal muscle strength,MMS)所對應之一最大容忍負壓值，此時氣流量測單元105量測人體30無吸氣氣流，而輸出呼吸狀態為異常時之回授訊號FB至運算單元104，以致負壓產生單元101依據此時的控制訊號CON而停止產生負壓氣流NP，並結束 系統鑑別階段。 When the respiratory muscle training system 10 is turned on, a system identification phase is first entered, and the negative pressure generating unit 101 of the respiratory muscle training system 10 generates a negative pressure airflow NP, and applies a negative pressure airflow NP via the airflow conduit 1013 and the sealing member 1011. The oral respiratory tract 301 of the human body 30 and the nasal respiratory tract 303 gradually increase the pressure of the negative pressure airflow NP, that is, gradually increase the flow rate of the gas extracted by the negative pressure generating unit 101 until the human body 30 cannot inhale the gas, and the negative pressure airflow at this time The pressure of the NP is defined as one of the maximum tolerated negative pressure values corresponding to the maximum muscle strength (MMS) of the human body 30. At this time, the gas flow measuring unit 105 measures that the human body 30 has no inspiratory airflow, and the output respiratory state is The feedback signal FB is sent to the arithmetic unit 104 when the abnormality occurs, so that the negative pressure generating unit 101 stops generating the negative pressure airflow NP according to the control signal CON at this time, and ends. System identification phase.
結束系統鑑別階段後，使用者可選擇進行維持訓練模式或漸進式訓練模式，維持訓練模式為呼吸肌訓練系統10之負壓產生單元101產生並維持負壓氣流NP之壓力為一固定壓力，固定壓力例如可為百分之八十的最大容忍負壓值之負壓氣流NP，而將此負壓氣流NP施加至人體30之口腔呼吸道301與鼻腔呼吸道303，直到人體30無法吸入氣體，則氣流量測單元105輸出對應呼吸異常之回授訊號FB，使負壓產生單元101依據此時的控制訊號CON而停止產生負壓氣流NP，並可定義所進行之維持訓練時間為總訓練時間TDT(Total duration time)，以作為評估人體30的呼吸肌耐力的依據，若可維持越長訓練時間TDT則判斷人體30之呼吸肌耐力越高，維持越短訓練時間TDT則反之。其中，本發明之維持訓練模式並不限定維持在百分之八十的最大容忍負壓值之負壓氣流NP，亦可依使用者之喜好而調整負壓氣流NP之壓力。 After the system identification phase is ended, the user may select to perform a maintenance training mode or a progressive training mode, and the maintenance training mode is that the negative pressure generating unit 101 of the respiratory muscle training system 10 generates and maintains the pressure of the negative pressure airflow NP to a fixed pressure, and is fixed. The pressure may be, for example, a negative pressure airflow NP of 80% of the maximum tolerated negative pressure value, and the negative pressure airflow NP is applied to the oral airway 301 of the human body 30 and the nasal respiratory tract 303 until the human body 30 is unable to inhale the gas. The measuring unit 105 outputs a feedback signal FB corresponding to the breathing abnormality, so that the negative pressure generating unit 101 stops generating the negative pressure airflow NP according to the control signal CON at this time, and can define the maintenance training time to be the total training time TDT ( Total duration time) is used as a basis for evaluating the respiratory muscle endurance of the human body 30. If the longer training time TDT can be maintained, the higher the respiratory muscle endurance of the human body 30 is determined, and the shorter the training time TDT is maintained. The maintenance training mode of the present invention does not limit the negative pressure airflow NP maintained at 80% of the maximum tolerated negative pressure value, and the pressure of the negative pressure airflow NP can be adjusted according to the user's preference.
漸進式訓練模式為呼吸肌訓練系統10之負壓產生單元101產生百分之二十的最大容忍負壓值之負壓氣流NP，並逐漸提升負壓氣流NP之壓力，直到人體30無法吸入氣體，則氣流量測單元105輸出對應呼吸異常之回授訊號FB，使負壓產生單元101依據此時的控制訊號CON而停止產生負壓氣流NP。 The progressive training mode is that the negative pressure generating unit 101 of the respiratory muscle training system 10 generates a negative pressure airflow NP of 20% of the maximum tolerated negative pressure value, and gradually increases the pressure of the negative pressure airflow NP until the human body 30 cannot inhale the gas. Then, the air flow measuring unit 105 outputs the feedback signal FB corresponding to the breathing abnormality, so that the negative pressure generating unit 101 stops generating the negative pressure airflow NP according to the control signal CON at this time.
其中，於漸進式訓練模式時，可藉由一肌肉量測單元，以量測人體30之肌力訊號，用以評估人體30的肌力強度，而此肌肉量測單元可為一機械式加速規(Accelerometer)、壓電電壓式加速規、電荷式加速規或電容式加速規，而設置於人體30之任意欲量測之部位，以量測該部位之肌肉表面振動，而進行肌動圖 (Mechanomyogrphy)的分析，當所量測之部位的皮膚表面振動幅度越大，則判斷此部位之肌力強度越高，若皮膚表面振動幅度越小則反之，或為一般電極貼片，而量測人體30之任意部位之肌肉的電位活性(electric activity)，以進行肌電圖(Electromyography，EMG)的分析，以作為評估人體30的呼吸肌肌力強度的依據。 Wherein, in the progressive training mode, the muscle force signal of the human body 30 can be measured by a muscle measuring unit for evaluating the muscle strength of the human body 30, and the muscle measuring unit can be a mechanical acceleration. Accelerometer, piezoelectric voltage accelerometer, charge accelerometer or capacitive accelerometer, and placed in any part of the human body 30 to measure the vibration of the muscle surface of the part, and perform the motion map (Mechanomyogrphy) analysis, when the measured surface of the skin surface vibration amplitude is greater, it is judged that the muscle strength of this part is higher, if the skin surface vibration amplitude is smaller, the opposite is true, or the general electrode patch, and the amount The electric activity of the muscle of any part of the human body 30 is measured for electromyography (EMG) analysis as a basis for evaluating the strength of the respiratory muscles of the human body 30.
此外，本發明之密封件1011並不限定為一口鼻式面罩，其亦可僅設置於人體30之口部，而例如利用一鼻夾將鼻部夾住而密封，並僅施加負壓氣流NP至人體30之口腔呼吸道，亦可達到上述之功效。 In addition, the sealing member 1011 of the present invention is not limited to a one-nose nasal mask, and it may be disposed only at the mouth of the human body 30, and for example, a nose clip is used to clamp the nose to seal, and only a negative pressure airflow NP is applied. To the oral cavity of the human body 30, the above effects can also be achieved.
另外，於此實施例中，是藉由回授電路102而判斷人體30是否呼吸異常，也就是判斷人體30是否還有吸氣氣流，然而本發明不僅限於此，亦可藉由一自覺指數量表(Borg Rated Perceived Exertion scale，RPE)，而讓人體30自行判斷是否可繼續進行訓練，自覺指數量表是一種教練用以訓練運動員的簡單測量方式，可用來評估進行某一強度之運動時的身體生理參數，如心跳、呼吸速率與出汗程度的量表，其一共分為15個等級，分數越低表示越無感，分數越高則表示進行此運動的強度越吃力。 In addition, in this embodiment, it is determined by the feedback circuit 102 whether the human body 30 is breathing abnormally, that is, whether the human body 30 still has an inspiratory airflow. However, the present invention is not limited thereto, and may also be consciously referred to by the number. Borg Rated Perceived Exertion scale (RPE), and let the body 30 judge whether it can continue training. The conscious scale is a simple measurement method used by the coach to train the athlete. It can be used to evaluate the exercise of a certain intensity. Physical physiological parameters, such as heart rate, respiratory rate and degree of sweating, are divided into 15 levels. The lower the score, the less sensation. The higher the score, the more difficult the intensity of the exercise.
請一併參閱2A與2B圖，第2A圖為本發明之第二實施例之呼吸肌訓練系統的方塊圖，第2B圖為本發明之第二實施例之呼吸肌訓練系統與人體連接的示意圖。本實施例與第一實施例之差異僅在於，本實施例之呼吸量測模組103包含一肌肉量測單元106，且藉由肌肉量測單元106量測人體之呼吸狀態，而其餘則不再贅述。 Please refer to FIG. 2A and FIG. 2B together, FIG. 2A is a block diagram of a respiratory muscle training system according to a second embodiment of the present invention, and FIG. 2B is a schematic diagram of a respiratory muscle training system according to a second embodiment of the present invention connected to a human body. . The difference between the present embodiment and the first embodiment is that the spirometry module 103 of the present embodiment includes a muscle measuring unit 106, and the muscle measuring unit 106 measures the breathing state of the human body, while the rest is not Let me repeat.
如圖所示，肌肉量測單元106藉由偵測人體30之下頦部由肌肉誘發的皮膚表面振動，以得知人體30之呼吸狀態，並產生對應之回授訊號FB。其中，肌肉量測單元106可為一機械式加速規(Accelerometer)、壓電電壓式加速規、電荷式加速規或電容式加速規，而設置於人體30之下頦部，並感測下頦部由肌肉誘發之皮膚表面振動的加速度，以進行肌動圖(Mechanomyogrphy，MMG)的分析，而得知人體30之呼吸狀態，當人體30之呼吸狀態為正常時，人體30之下頦部之皮膚表面的振動幅度較小，也就是較為穩定的狀態，而當人體30之呼吸狀態為異常(呼吸中止)時，人體30會因呼吸中止而導致下頦部之皮膚表面的振動幅度會較大，因此肌肉量測單元106會依據所量測到人體30之下頦部由肌肉誘發的皮膚表面振動，而輸出對應的回授訊號FB。 As shown in the figure, the muscle measuring unit 106 detects the skin surface vibration induced by the muscles of the lower part of the human body 30 to know the breathing state of the human body 30, and generates a corresponding feedback signal FB. The muscle measuring unit 106 can be a mechanical accelerometer, a piezoelectric voltage accelerometer, a charge accelerometer or a capacitive accelerometer, and is disposed under the crotch of the human body 30 and senses the squat. The acceleration of the skin surface vibration induced by the muscle, for the analysis of the mechanomyogrphy (MMG), and the breathing state of the human body 30, when the breathing state of the human body 30 is normal, the lower part of the human body 30 The vibration amplitude of the skin surface is small, that is, a relatively stable state, and when the breathing state of the human body 30 is abnormal (breathing is stopped), the vibration amplitude of the skin surface of the lower jaw is larger due to the suspension of the human body 30. Therefore, the muscle measuring unit 106 outputs the corresponding feedback signal FB according to the measured skin surface vibration induced by the muscle in the lower part of the human body 30.
但本發明之肌肉量測單元106並不限定設置於人體30之下頦部，並偵測人體30之下頦部表面的肌肉振動，亦可將肌肉量測單元106設置於人體30的其他部位(例如胸部或背部等)，只要是可以藉由量測肌肉而得之呼吸狀態與呼吸肌強度，即符合本發明之精神。如第2C圖本發明之第二實施例之肌肉量測單元的貼附示意圖所示，本發明之肌肉量測單元106亦可貼附於人體30之胸部，以量測由胸部之肌肉誘發的皮膚表面振動，而得知人體30之呼吸狀態或呼吸肌強度。或者可藉由偵測人體30肌肉的電位活性(electric activity)，以進行肌電圖(Electromyography，EMG)的分析，而得知人體30之呼吸狀態，而肌電圖為本領域中所熟知的，所以在此不再贅述。 However, the muscle measuring unit 106 of the present invention is not limited to the lower part of the human body 30, and detects the muscle vibration of the lower surface of the human body 30. The muscle measuring unit 106 can also be disposed at other parts of the human body 30. (For example, the chest or the back, etc.), as long as it is a respiratory state and a respiratory muscle strength which can be obtained by measuring muscles, it is in accordance with the spirit of the present invention. As shown in the attached view of the muscle measuring unit of the second embodiment of the present invention, the muscle measuring unit 106 of the present invention can also be attached to the chest of the human body 30 to measure the muscle induced by the chest. The skin surface vibrates and the respiratory state or respiratory muscle strength of the human body 30 is known. Alternatively, the respiratory state of the human body 30 can be known by detecting the electric activity of the muscles of the human body 30 to perform electromyography (EMG) analysis, and the electromyogram is well known in the art. , so I won't go into details here.
請一併參閱第2D圖，其係為本發明之第二實施例之呼吸肌訓 練系統與人體連接的狀態示意圖。如圖所示，肌肉量測單元106設置於人體30之下頦部的表面，以偵測人體30之下頦部的皮膚表面振動。當人體30之呼吸狀態為呼吸正常時，由於下頦部的皮膚表面振動幅度會較小，因此肌肉量測單元106得知為呼吸正常，而輸出對應呼吸狀態為正常時之回授訊號FB，以致負壓產生單元101持續產生負壓氣流NP，以提供至人體30之口腔呼吸道301與鼻腔呼吸道303。 Please refer to FIG. 2D, which is a respiratory muscle training of the second embodiment of the present invention. A schematic diagram of the state of the connection between the system and the human body. As shown, the muscle measuring unit 106 is disposed on the surface of the crotch portion of the lower body 30 to detect skin surface vibration of the crotch portion of the human body 30. When the breathing state of the human body 30 is normal breathing, since the skin surface vibration amplitude of the lower jaw portion is small, the muscle measuring unit 106 knows that the breathing is normal, and outputs the feedback signal FB corresponding to the normal breathing state. The negative pressure generating unit 101 continues to generate the negative pressure airflow NP to provide the oral airway 301 and the nasal respiratory tract 303 to the human body 30.
而當人體30無法承受負壓氣流NP時，由於下頦部的皮膚表面振動幅度會較大，因此肌肉量測單元106得知為呼吸異常，而輸出對應呼吸異常之回授訊號FB至運算單元104，以致負壓產生單元101停止提供負壓氣流NP，以防止人體30發生危險。 When the human body 30 cannot withstand the negative pressure airflow NP, since the amplitude of the skin surface vibration of the lower jaw portion is large, the muscle measuring unit 106 knows that the breathing is abnormal, and outputs the feedback signal FB corresponding to the breathing abnormality to the arithmetic unit. 104, so that the negative pressure generating unit 101 stops supplying the negative pressure airflow NP to prevent the human body 30 from being in danger.

FIG. 3A is a block diagram of a respiratory muscle training system according to a third embodiment of the present invention, and FIG. 3B is a schematic diagram of a respiratory muscle training system according to a third embodiment of the present invention. .

For the feedback signal FB, the control signal CON is generated by comparison with the reference signal REF. That is, the reference gas flow measuring unit 105 and the muscle measuring unit 106 measure the breathing state of the human body 30 respectively. Fifty, and the remaining principles are as described in the first embodiment and the second embodiment, and are not described herein again.
請參閱第4圖，其為本發明之第四實施例之呼吸肌訓練系統的方塊圖。此實施例與第三實施例之差異在於，此實施例在氣流 量測單元105與運算單元104之間連接一加權單元107，而在肌肉量測單元106與運算單元104之間連接一加權單元108，其餘部分則相同，所以不再贅述。 Please refer to FIG. 4, which is a block diagram of a respiratory muscle training system according to a fourth embodiment of the present invention. The difference between this embodiment and the third embodiment is that this embodiment is in the air flow A weighting unit 107 is connected between the measuring unit 105 and the computing unit 104, and a weighting unit 108 is connected between the muscle measuring unit 106 and the computing unit 104. The rest are the same, so they are not described again.
如圖所示，加權單元107用於將氣流量測單元105產生之氣流回授訊號FB1乘以一氣流加權值，以產生一氣流加權訊號W1，加權單元108用於將肌肉量測單元106產生之肌肉回授訊號FB2乘以一肌肉加權值，以產生一肌肉加權訊號W2，而運算單元104則相加氣流加權訊號W1與肌肉加權訊號W2後作為回授訊號FB，以與參考訊號REF做比較。 As shown in the figure, the weighting unit 107 is configured to multiply the airflow feedback signal FB1 generated by the airflow measuring unit 105 by an airflow weighting value to generate an airflow weighting signal W1, and the weighting unit 108 is configured to generate the muscle measuring unit 106. The muscle feedback signal FB2 is multiplied by a muscle weighting value to generate a muscle weighting signal W2, and the arithmetic unit 104 adds the airflow weighting signal W1 and the muscle weighting signal W2 as a feedback signal FB to perform with the reference signal REF. Comparison.
其中，氣流加權值與肌肉加權值可依據使用者所需而做設定，例如將氣流加權值設定為0.8，而將肌肉加權值設定為0.2時，呼吸肌訓練系統10參考氣流量測單元105與肌肉量測單元106量測人體30之呼吸狀態的比重分別為百分之八十與百分之二十。如此，本實施例可藉由調整加權單元107、108之氣流加權值與肌肉加權值，以調整欲參考氣流量測單元105與肌肉量測單元106量測人體30之呼吸狀態的比重。 The airflow weighting value and the muscle weighting value may be set according to the user's needs, for example, the airflow weighting value is set to 0.8, and when the muscle weighting value is set to 0.2, the respiratory muscle training system 10 refers to the airflow measuring unit 105 and The muscle measuring unit 106 measures the respiratory state of the human body 30 by 80% and 20%, respectively.

請參閱第5圖，其為本發明之第五實施例之呼吸肌訓練系統的方塊圖。如圖所示，本實施例與前一實施例之差異在於，本實施例之呼吸肌訓練系統10更包含一警示單元109，警示單元109用以依據控制訊號CON而發出警示訊號，例如，當人體30之呼吸狀態為異常時，警示單元109則依據此時的控制訊號CON發出警示訊號，以提醒使用者、醫師或周遭的人，此時人體30為呼吸異常。其中，警示單元109可為一蜂鳴器、警示燈或顯示裝置，而警示訊號則可為蜂鳴器發出之聲音、警示燈所發出不同顏色之光或顯 示裝置所顯示之影像或字幕。 Please refer to FIG. 5, which is a block diagram of a respiratory muscle training system according to a fifth embodiment of the present invention. As shown in the figure, the difference between the present embodiment and the previous embodiment is that the respiratory muscle training system 10 of the present embodiment further includes a warning unit 109, and the warning unit 109 is configured to issue a warning signal according to the control signal CON, for example, when When the breathing state of the human body 30 is abnormal, the warning unit 109 sends a warning signal according to the control signal CON at this time to remind the user, the doctor or the surrounding person, and the human body 30 is abnormal in breathing. The warning unit 109 can be a buzzer, a warning light or a display device, and the warning signal can be the sound of the buzzer, the light of different colors emitted by the warning light or the display The image or subtitle displayed by the device.
請參閱第6圖，其為本發明之呼吸肌訓練方法之流程圖。如圖所示，步驟S10至S50為系統鑑別階段，也就是用以判斷人體30之最大肌肉強度MMS所對應的最大容忍負壓值的鑑別階段。首先執行步驟S10，將密封件1011貼附於人體30之面部。接著，執行步驟S20，啟動呼吸肌訓練系統10，以使負壓產生單元101產生一初始值的負壓氣流NP，並經由密封件1011而施加於人體30之呼吸道(口腔呼吸道301、鼻腔呼吸道303)。接著，執行步驟S30，逐漸提升負壓氣流NP之壓力，例如，如第7圖所示，其係為本發明之負壓上升之示意圖，其每90秒增加-7釐米水柱(cmH2O)的氣道壓力，而圖中之氣道壓力為相對於人體30之吸氣氣流，也就是每90秒增加-7毫米水柱之負壓氣流NP。 Please refer to FIG. 6 , which is a flow chart of the respiratory muscle training method of the present invention. As shown in the figure, steps S10 to S50 are the system identification stage, that is, the identification stage for judging the maximum tolerance negative pressure value corresponding to the maximum muscle strength MMS of the human body 30. First, step S10 is performed to attach the sealing member 1011 to the face of the human body 30. Next, step S20 is executed to start the respiratory muscle training system 10, so that the negative pressure generating unit 101 generates an initial value of the negative pressure airflow NP, and is applied to the respiratory tract of the human body 30 via the sealing member 1011 (the oral respiratory tract 301, the nasal respiratory tract 303). ). Then, step S30 is performed to gradually increase the pressure of the negative pressure airflow NP. For example, as shown in FIG. 7, it is a schematic diagram of the negative pressure rise of the present invention, which increases the -7 cm water column (cmH 2 O) every 90 seconds. The airway pressure in the figure is the inspiratory flow relative to the human body 30, that is, the negative pressure airflow NP which increases the -7 mm water column every 90 seconds.
執行上述步驟S30時，同時不斷執行步驟S40，藉由回授電路102量測人體30之呼吸狀態，並經回授電路102之運算單元104比較參考訊號REF與回授訊號FB之差異，而輸出對應呼吸狀態之控制訊號CON，若人體30有吸氣氣流時，不斷回到步驟S30提升負壓氣流NP，直到人體30無吸氣氣流(呼吸異常)時，負壓產生單元101依據此時的控制訊號CON停止產生負壓氣流NP，並執行步驟S50，將此時負壓氣流NP的壓力大小定義為人體30之最大肌肉強度MMS對應的最大容忍負壓值，以藉由上述步驟S10至S50鑑別出人體30所能忍受的最大負壓。 When the above step S30 is performed, the step S40 is continuously performed, and the breathing state of the human body 30 is measured by the feedback circuit 102, and the difference between the reference signal REF and the feedback signal FB is compared by the arithmetic unit 104 of the feedback circuit 102. Corresponding to the control signal CON of the breathing state, if the human body 30 has an inspiratory airflow, the process returns to step S30 to raise the negative pressure airflow NP until the human body 30 has no inspiratory airflow (breathing abnormality), and the negative pressure generating unit 101 is based on the current state. The control signal CON stops generating the negative pressure airflow NP, and performs step S50 to define the pressure magnitude of the negative pressure airflow NP at this time as the maximum tolerance negative pressure value corresponding to the maximum muscle strength MMS of the human body 30, by the above steps S10 to S50. Identify the maximum negative pressure that the human body 30 can tolerate.
接著可依使用者選擇欲執行的訓練，若要做呼吸肌肌耐力的訓練則執行步驟S60之維持訓練模式，而要做呼吸肌肌力強度的訓練則執行步驟S70之漸進訓練模式，維持訓練模式與漸進訓練 模式之詳細介紹如下所述。 Then, the user can select the training to be performed according to the user. If the training of the respiratory muscle strength is to be performed, the maintenance training mode of step S60 is performed, and the training of the muscle strength of the respiratory muscle is performed, and the progressive training mode of step S70 is performed to maintain the training. Mode and progressive training The details of the mode are described below.
請參閱第8圖，其為本發明之維持訓練模式之流程圖，步驟S60之維持訓練模式中包含步驟S601至S607。首先，執行步驟S601，此步驟為設定在維持訓練模式中欲施壓之負壓氣流NP的負壓值，於此實施例中，是將前述系統鑑別階段所定義出的最大容忍負壓值乘以百分之八十，以作為維持訓練模式中欲施壓之負壓氣流NP的負壓值，但本發明不以乘以百分之八十為限，亦可依使用者之需求做設定。接著，執行步驟S602，此步驟為設定訓練時間，而此訓練時間可由預先設定、使用者設定或依人體30過往進行維持訓練模式之訓練時間做參考而設定，但上述設定時間之方式亦並非用以限定本發明。 Please refer to FIG. 8 , which is a flowchart of the maintenance training mode of the present invention, and the maintenance training mode of step S60 includes steps S601 to S607 . First, step S601 is performed, which is a negative pressure value of the negative pressure airflow NP to be pressed in the maintenance training mode. In this embodiment, the maximum tolerance negative pressure value defined by the aforementioned system identification phase is multiplied. 80%, as the negative pressure value of the negative pressure airflow NP to be pressed in the maintenance training mode, but the invention is not limited to 80%, and can also be set according to the needs of the user. . Then, step S602 is performed. The step is to set the training time, and the training time can be set by using a preset, user setting or training time according to the body 30 to maintain the training mode. However, the method of setting the time is not used. To limit the invention.
接著，執行步驟S603，呼吸肌訓練系統10之負壓產生單元101產生上述步驟S601中所設定負壓值的負壓氣流NP，並維持負壓氣流NP之負壓值為固定壓力，而將此負壓氣流NP施加至人體30之呼吸道(口腔呼吸道301與鼻腔呼吸道303)。接著執行步驟S604與S605，步驟S604為量測人體30之呼吸狀態，當人體30之呼吸狀態為正常時回到步驟S603，繼續維持負壓氣流NP之負壓值，直到人體30之呼吸狀態為異常，即人體30無法吸入氣體以致無吸氣氣流時，則同時執行步驟S606與S607，停止產生負壓氣流NP以結束訓練，並發出警示訊號，以提醒使用者、醫師或周遭的人，此時人體30為呼吸異常。或者，當步驟在S605偵測到於步驟S602中所設定的訓練時間到達時，則亦執行步驟S607以結束訓練，但不發出警示訊號。 Next, in step S603, the negative pressure generating unit 101 of the respiratory muscle training system 10 generates the negative pressure airflow NP of the negative pressure value set in the above step S601, and maintains the negative pressure value of the negative pressure airflow NP as a fixed pressure. The negative pressure airflow NP is applied to the respiratory tract of the human body 30 (the oral respiratory tract 301 and the nasal respiratory tract 303). Then, steps S604 and S605 are performed. Step S604 is to measure the breathing state of the human body 30. When the breathing state of the human body 30 is normal, the process returns to step S603 to continue maintaining the negative pressure value of the negative pressure airflow NP until the breathing state of the human body 30 is Abnormal, that is, when the human body 30 is unable to inhale the gas so that there is no inspiratory airflow, steps S606 and S607 are simultaneously performed, the generation of the negative pressure airflow NP is stopped to end the training, and a warning signal is issued to remind the user, the physician or the surrounding person. The human body 30 is abnormal in breathing. Alternatively, when the step S605 detects that the training time set in step S602 arrives, step S607 is also performed to end the training, but no warning signal is issued.
其中，當人體30無吸氣氣流時，是由呼吸量測模組103輸出 對應呼吸異常之回授訊號FB，使負壓產生單元101依據此時的控制訊號CON而停止產生負壓氣流NP，且此處可包含前述確定人體30為呼吸異常的時間，例如當運算單元104接收對應呼吸異常之回授訊號FB3秒，運算單元104才輸出對應呼吸異常的控制訊號CON至負壓產生單元101與警示單元109，以執行步驟S606與S607。而當訓練時間到達時，可由負壓產生單元101本身依據訓練時間停止產生負壓氣流NP。 Wherein, when the human body 30 has no inspiratory airflow, it is output by the respiratory measurement module 103. The feedback signal FB corresponding to the breathing abnormality causes the negative pressure generating unit 101 to stop generating the negative pressure airflow NP according to the control signal CON at this time, and may include the foregoing determining the time when the human body 30 is a breathing abnormality, for example, when the operation unit 104 The arithmetic unit 104 outputs the control signal CON corresponding to the abnormal breathing to the negative pressure generating unit 101 and the warning unit 109 to execute steps S606 and S607. When the training time arrives, the negative pressure generating unit 101 itself can stop generating the negative pressure airflow NP according to the training time.
此外，當執行步驟S607而結束訓練後，可定義所進行之維持訓練模式的時間為總訓練時間TDT，以作為評估人體30的呼吸肌耐力的依據，例如，此次總訓練時間TDT為2分鐘，而下次訓練的總訓練時間TDT為3分鐘，則可得知人體30之呼吸肌耐力有所進步。 In addition, after performing the step S607 and ending the training, the time for maintaining the training mode can be defined as the total training time TDT as a basis for evaluating the respiratory muscle endurance of the human body 30, for example, the total training time TDT is 2 minutes. And the total training time TDT of the next training is 3 minutes, it can be known that the respiratory muscle endurance of the human body 30 has improved.

First, step S701 is performed, which is an initial negative pressure value of the negative pressure airflow NP to be pressed in the progressive training mode. In this embodiment, the maximum tolerance negative pressure defined by the aforementioned system identification phase is determined. The value is multiplied by 20% to maintain the initial negative pressure value of the negative pressure airflow NP to be pressed in the training mode, but the present invention is not limited to 20%, and may also be based on the user. Demand is set. Next, step S702 is executed to set the training time. This part is the same as step S602 of maintaining the training mode, and will not be described again.
接著，執行步驟S703，呼吸肌訓練系統10之負壓產生單元101產生初始負壓值之負壓氣流NP，也就是百分之二十的最大容忍負壓值之負壓氣流NP，而將此負壓氣流NP施加至人體30之呼吸道。接著，執行步驟S704，逐漸增加負壓氣流NP之負壓值，並同 時不斷執行步驟S705與S706，步驟S705為量測人體30之呼吸狀態，當人體30之呼吸狀態為正常時回到步驟S704，繼續增加負壓氣流NP之負壓值，直到人體30無法吸入氣體以致無吸氣氣流時，則同時執行步驟S707與S708，停止產生負壓氣流NP以結束訓練，並發出警示訊號。或者，當步驟在S706偵測到於步驟S202中所設定的訓練時間到達時，則亦執行步驟S708以結束訓練，但不發出警示訊號。 Next, in step S703, the negative pressure generating unit 101 of the respiratory muscle training system 10 generates a negative pressure airflow NP of an initial negative pressure value, that is, a negative pressure airflow NP of a maximum tolerance negative pressure value of 20%, and this The negative pressure airflow NP is applied to the respiratory tract of the human body 30. Then, step S704 is performed to gradually increase the negative pressure value of the negative pressure airflow NP, and the same Steps S705 and S706 are continuously performed. Step S705 is to measure the breathing state of the human body 30. When the breathing state of the human body 30 is normal, the process returns to step S704 to continue increasing the negative pressure value of the negative pressure airflow NP until the human body 30 cannot inhale the gas. When there is no inspiratory airflow, steps S707 and S708 are simultaneously performed, the generation of the negative pressure airflow NP is stopped to end the training, and a warning signal is issued. Alternatively, when the step detects that the training time set in step S202 arrives in S706, step S708 is also performed to end the training, but no warning signal is issued.
另外，本發明亦可當在步驟S704中，負壓氣流NP之負壓值增加至一上限值時，亦執行步驟S708，負壓產生單元101停止產生負壓氣流NP，結束訓練以防止危險發生，此上限值可設定為百分之九十的最大容忍負壓值。 In addition, in the present invention, when the negative pressure value of the negative pressure airflow NP is increased to an upper limit value in step S704, step S708 is also performed, and the negative pressure generating unit 101 stops generating the negative pressure airflow NP, and ends the training to prevent the danger. Occurs, this upper limit can be set to a maximum tolerance negative pressure of ninety percent.
此外，在維持訓練模式或漸進式訓練模式中，皆可藉由一肌肉量測單元量測人體30之肌力訊號，用以評估人體30在訓練時之呼吸肌的肌力強度，例如，藉由加速規量測某部位之肌肉誘發之皮膚表面振動，而進行肌動圖的分析，當此次所量測之部位的表面振動大於前次之表面振動，則判斷此部位之肌力強度有所進步。 In addition, in the maintenance training mode or the progressive training mode, the muscle force signal of the human body 30 can be measured by a muscle measuring unit to evaluate the muscle strength of the respiratory muscles of the human body 30 during training, for example, The acceleration surface measures the vibration of the skin surface induced by the muscle of a certain part, and performs the analysis of the myocardogram. When the surface vibration of the measured part is greater than the previous surface vibration, the muscle strength of the part is judged to have Progress.
