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.

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.

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.

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.

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.

Therefore, the present invention provides a negative pressure breathing muscle training system and method for exercising the human respiratory muscles and vital capacity by applying negative pressure to the human body to breathe.

An object of the present invention is to provide a negative pressure breathing muscle training method for training the muscle strength of a respiratory muscle of a human body by outputting a negative pressure airflow to the respiratory tract of the human body and gradually increasing the pressure of the negative pressure airflow.

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).

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).

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

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.

Please refer to FIG. 3A and FIG. 3B together. 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. . As shown in the figure, in the embodiment, in combination with the first embodiment and the second embodiment, the respiratory measurement module 103 includes the gas flow measuring unit 105 and the muscle measuring unit 106 simultaneously by the gas flow measuring unit 105 and The muscle measuring unit 106 measures the breathing state of the human body 30, and the arithmetic unit 104 adds one of the airflow feedback signal FB1 and the muscle feedback signal FB2 generated by the airflow measuring unit 105 and the muscle measuring unit 106 respectively. 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.

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.

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.

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. Thus, in this embodiment, by adjusting the airflow weighting value and the muscle weighting value of the weighting units 107, 108, the specific gravity of the breathing state of the human body 30 to be measured by the gas flow measuring unit 105 and the muscle measuring unit 106 is adjusted.

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.

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.

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.

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.

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.

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.

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.

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.

Please refer to FIG. 9 , which is a flowchart of the progressive training mode of the present invention, and the progressive training mode of step S70 includes steps S701 to S708 . 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.

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.

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.

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.

In summary, the negative pressure breathing muscle training system and method of the present invention applies a negative pressure airflow to the respiratory tract of a human body by a negative pressure generating unit to serve as a resistance to inhalation of the human body, thereby training the breathing of the human body. Muscle, and measure the breathing state of the human body by a feedback circuit to judge whether the respiratory muscle of the human body is fatigued and unable to inhale the gas according to the breathing state, and stop applying negative pressure to the human body to avoid danger of the human body during training. .
