Summary of the Invention

Problems to be Solved by the Invention

[0004] The above-mentioned training method has the following drawbacks. First, the rules are complex, and it is very important to maintain consistency. The trainer needs to fully understand and adjust the timing, flow rate or volume, and number of repeated inhalation and exhalation combinations during training. Without a way to maintain consistency, it will also affect the effect, so how to maintain the consistency of training goals becomes a major issue. Furthermore, during training, it is necessary to firmly hold the lips on the mouthpiece. However, middle-aged and elderly patients with neuromuscular degeneration disorders, cognitive impairments, memory impairments, and communication impairments often cannot understand the instructions throughout the process or cannot tighten their lips.

[0005] Based on the above, there is a need for a method and device for exercising the respiratory muscle group to solve the problems of the prior art.

Means for Solving the Problem

[0006] The present invention provides a device for training the respiratory muscle group through an adjustable resistance during the inhalation or exhalation process, simulating the inhalation flow, being equivalent to the piston lifting effect of an inductive spirometer, and can be used to improve lung function. For example, vital capacity and atelectasis can be utilized for the recovery of postoperative patients, the improvement of the overall health of the respiratory system, the increase in the amount of inhaled oxygen, etc.

[0007] Furthermore, the respiratory muscle group training device of the present invention does not need to use an external air pressure source. With adjustable resistance, it simulates respiratory obstruction, generates negative pressure during the user's inhalation process, and gradually improves the strength of the dilators. The present invention can be used as a basis for guiding the user to perform respiratory actions for training the upper airway muscle group by measuring the physiological parameters of the changes in the upper airway muscle group during training, so as to achieve the effect of improving the muscle strength of the upper airway muscle group.

[0008] In one embodiment, the present invention provides a respiratory muscle group training device including a hood body, an airflow adjustment element, a respiratory fluid state sensor, and an arithmetic processing unit. The hood body is used to cover the user's face with respect to the intake port and the exhaust port. An airflow adjustment element is arranged in the hood body, and by setting the intake resistance, respiratory-related muscle groups such as respiratory function-related muscle groups and upper airway muscle groups can be trained according to the intake target. A respiratory fluid state sensor is attached to the hood body, and sensing information is detected and generated when the user makes movements such as inhaling and exhaling. Training reference information regarding respiratory function is provided to the arithmetic processing unit, and since the arithmetic processing unit is electrically connected to the respiratory fluid state sensor, it is determined whether the training reference information is satisfied according to the respiratory information.

[0009] In one embodiment, the present invention provides a respiratory muscle group training device including a hood, a physiological parameter detection element, and an arithmetic processing unit. The hood is used to cover the respiratory area of the user's face, and there is a valve body electrically connected to a control device in the hood. The valve body receives a control device that adjusts the intake resistance to simulate airway obstruction and creates a negative pressure in the airway when the user inhales. The physiological parameter detection element is used to measure physiological parameters regarding the user's respiratory movement state during the user's respiratory process under the intake resistance. The arithmetic processing unit is electrically connected to the physiological parameter detection element, and the arithmetic processing unit adjusts the training mode according to the physiological parameters.

[0010] In one embodiment, the present invention provides at least one detection element that can extend into the oral cavity. When the upper airway muscle group contracts due to exhalation or inhalation movement with a resistance mask, the detection element can evaluate the contraction function of the upper airway muscle group, particularly the speed and degree of muscle contraction under different resistances or flow pressures. The detection elements can be divided into contact type and non-contact type. The detection elements can be divided into contact type and non-contact type. (1) Contact mechanomyography (MMG) uses a piezoelectric chip to measure the vibration frequency on the muscle surface and measures the degree of muscle contraction. Also, the changes in the muscle can be directly observed using the M-mode and B-mode of ultrasound. (2) Non-contact means observing the hot spots of muscle contraction using thermal imaging technology, observing the changes in the appearance of the soft palate such as the shape and angle changes of the palatopharyngeal arch using a CCD camera, or performing direct observation by 3D stereo imaging.

Advantages of the Invention

[0011] The muscle group training device of the present invention provides a device for training the respiratory muscle group and can be used to improve respiratory and lung functions. Also, by measuring the physiological parameters of the changes in the upper airway muscle group during training, the measured physiological parameter information can be used as a basis to guide the user to perform respiratory behaviors to improve the muscle strength of the upper airway muscle group, and it has the effect of improving the muscle strength of the upper airway muscle group.

Mode for Carrying Out the Invention

[0013] The following will more fully describe various embodiments with reference to the diagrams, in which some exemplary embodiments are shown. However, the concept of this utility model can be embodied in many different forms and should not be construed as limited to the exemplary embodiments described herein. Specifically, the provision of such exemplary embodiments makes the present invention more detailed and complete, and the scope of the concept of the present invention can be fully conveyed to those skilled in the art. Similar numerical values always indicate similar components. The following are various embodiments including schematic diagrams illustrating an apparatus for training the respiratory muscle group, and the following embodiments are not used to limit the present invention.

[0014] Please refer to FIG. 1. This is a schematic diagram of one process of a method for training the respiratory muscle group of the present invention. The method 2 for training the respiratory muscle group in this embodiment is for training respiratory function, and the following will explain the lung function. First, step 20 is to provide a respiratory muscle group training device. In step 20, the respiratory muscle group training device has various embodiments and mainly simulates airway obstruction during the inhalation process through an adjustable inhalation resistance. The respiratory muscle group referred to in the present invention is related to the muscle groups of respiratory function and upper airway muscles, but is not limited thereto, and will be described below by the muscle groups related to lung function. In one embodiment, as shown in FIG. 2A, the figure is a schematic diagram of one embodiment of the respiratory muscle group training device of the present invention. In this embodiment, the respiratory muscle group training device 3 includes a hood body 30 and an arithmetic processing unit 32. The hood body 30 is used to cover the inhalation / exhalation position on the face of the user 9 and can be placed at the user's mouth, nose, or the position of the mouth and nose without limitation.

[0015] The hood body 30 is provided with an air flow adjustment element 31 and an air pressure detection element 34. The airflow adjustment element 31 is used to adjust the amount of airflow flowing from the external environment into the interior of the hood 30. In one embodiment, the airflow adjustment element 31 may be of an adjustable type. For example, the sizes of the airflow inlet and outlet openings can be controlled by a remote unit or an intelligent handheld unit, such as the arithmetic processing unit 32. To control the adjustment valve, the control element 310 arranged on the airflow adjustment element 31 can be controlled to control the adjustment valve, check valve, or the flow controller of the airflow adjustment element 31. Further, the airflow adjustment element 31 may also be non-adjustable. For example, in another embodiment, the airflow adjustment element 31 is provided with at least one opening, and the flow of inlet air can be controlled by controlling the size of the opening or the degree of shielding. The air flow rate entering the hood body 30 from the external environment can be adjusted manually or electrically. In another embodiment, when the airflow adjustment element 31 is designed with holes, the purpose of adjusting the inlet air flow rate can be achieved through elements with different opening ratios. The air pressure detection element 34 is arranged on the hood body 30 and is used for detecting air pressure information when the hood body 30 performs inhalation or exhalation movements, such as detecting the air pressure in the oral cavity during inhalation or exhalation. In this embodiment, the air pressure detection element 34 is arranged on the inner surface of the hood body 30. Note that in this embodiment, the hood body 30 is further provided with a wireless communication element 35 such as an RFID, WiFi wireless communication, short-range wireless communication element, or Bluetooth element, but it is not limited thereto. The wireless communication element 35 can transmit the air pressure information detected by the air pressure detection element 34 to the arithmetic processing unit 32 through a wireless mode.

[0016] The arithmetic processing unit 32 is electrically connected or coupled to the airflow adjustment element 31 and the air pressure detection element 34, and training reference information is provided in the arithmetic processing unit 32. In one embodiment, the arithmetic processing unit 32 determines whether the training reference information is reached according to the sensed information. In one embodiment, the arithmetic processing unit 32 may be an intelligent handheld or wearable unit such as a smartphone, a tablet computer, or a wearable watch or microprocessor attached to the hood body 30. Also, the arithmetic processing unit 32 may be a notebook computer, a cloud server, or the like. In this embodiment, the arithmetic processing unit 32 is a smartphone, and a display unit 320 is provided for obtaining the training reference information, the resistance information for the air flow rate, and the pressure information detected by the air pressure detection element 34. The display unit 320 can be a display unit, an audio unit, or another vibration feedback unit. In this embodiment, the display unit 320 is a display unit, for example, a display screen. The arithmetic processing unit 32 sends out a control signal for remotely controlling the intake air volume of the airflow adjustment element 31. In another embodiment, as shown in FIG. 2B, this figure is a schematic diagram of another embodiment of the respiratory muscle group training device of the present invention. In this embodiment, it is basically the same as FIG. 2A, but in this embodiment, an air supply unit 36 is further configured to supply oxygen, steam, or oxygen is combined with a steam pipe and an air supply pipe 360 combined with the hood body is provided to the user as the oxygen or steam required for the training process. As shown in FIG. 2C, this figure is a schematic diagram of another embodiment of the respiratory muscle group training device of the present invention. In this embodiment, the air supply unit 36 communicates with one side of the hood body 30. In this embodiment, the airflow adjustment element 31 is arranged on the hood body 30 or on the air supply pipe 360 of the air supply unit 36 to adjust the oxygen flow rate supplied to the hood body 30 by the air supply unit 36 when the user inhales and simulate the effect of the inhalation resistance. In another embodiment, as shown in FIG. 2D, a respiratory fluid state sensor 37, for example, a pressure sensor, a thermal sensor, a flow sensor, or a combination thereof, is coupled to the air supply pipe 360.Note that the airflow adjustment element 31 and the respiratory fluid state sensor 37 can be integrated or separated into one from two independent elements. In another embodiment, as shown in FIG. 2E, in this embodiment, the respiratory fluid state sensor 37 is more equipped with a pipeline 370 and is coupled to the air supply pipeline 360. In another embodiment, as shown in FIG. 2F, the pipeline 370 of the respiratory fluid state sensor 37 is coupled to the hood body 30. Note that in this embodiment, the airflow adjustment element 31 can also be arranged on the hood body 30.

[0017] Returning to FIG. 1 and proceeding to step 21, determine the negative pressure required for training, determine the required airflow and air exchange volume, and perform training on respiratory-related muscle groups, such as, but not limited to, lung function and upper airway muscle groups. In the embodiment of step 21, taking the embodiment of FIG. 2A as an example, since the airflow adjustment element 31 is provided, by the method of determining the negative pressure, the user can adjust the air intake amount of the airflow adjustment element 31 manually or remotely. For example, through an application executed on the arithmetic processing unit 32, communication with the airflow adjustment element 31 can be achieved, the intake air volume of the airflow adjustment element 31 can be controlled wirelessly, and when the user inhales, the amount of air entering the hood body 30 from the external environment can be adjusted, and the magnitude of the airflow represents the resistance received by the user when inhaling. When the user inhales, if the flow or air exchange volume of the air entering through the airflow adjustment element 31 is small, it means that the inhalation resistance is large and it is difficult for the user to inhale air. Conversely, when the user inhales, if the flow or air exchange volume of the air entering through the airflow adjustment element 31 is large, the inhalation resistance is small and the user can easily inhale air, and the resistance required for training is generated by the negative pressure mode. In another embodiment, the required airflow or ventilation volume can be determined by inducing the user to utilize the amount of suction force during inhalation. In this embodiment, the airflow adjustment element 31 has an original fixed design. For example, the magnitude of the resistance on the airflow adjustment element is a fixed design.

[0018] Once the intake negative pressure is set, the next step 22 is to set the training reference information. In an embodiment of step 22, for example, the setting can be performed by the arithmetic processing unit 32 shown in FIG. 2A. In an embodiment, the arithmetic processing unit 32 executes an application, and through the user operation interface displayed by the application, the user can set the training reference information. In one embodiment, the training reference information may be, but is not limited to, the respiratory rate, exhalation / inhalation time, respiratory volume, flow rate, or any combination thereof. The respiratory rate is the number of breaths per unit time. For example, in another embodiment, the training reference information can also be set to the integrated value of the pressure change and time when the user breathes (which represents lung function). The work W done when the user performs a breathing movement can be expressed by the following formula (1). The information for determining the training reference includes step 220, where at least one set of breathing cycle patterns is input to simulate the sleep airway resistance or obstruction. This step is mainly to simulate the occlusion situation by setting various resistances. Then, step 221 is performed to observe the changes in the user's respiratory rate, exhalation / inhalation time, respiratory volume, and flow rate, estimate the state of lung function, and determine the training reference information. In this step, by setting different resistances in step 220, corresponding parameter information such as the respiratory rate, exhalation / inhalation time, respiratory volume, flow rate, or any combination of the above can be obtained, and then the training reference information can be formulated according to this information. Note that the training reference information is not necessarily determined using steps 220 and 221 described above. In another embodiment, the training reference information can also be set by oneself based on experience and then adjusted according to the situation.

[0019] After step 22, perform step 23 which is a training step, so that the user can achieve the training reference information by performing at least one inhalation or exhalation movement under the inhalation resistance. After the user sets the resistance and the training reference information in steps 21 and 22, the user can start the lung function training. In one embodiment, the training reference information is composed of at least one training cycle, and each cycle includes at least one inhalation movement, the number of which is determined according to the training needs of the user, and the user can set it through the application installed in the arithmetic processing unit 32.

[0020] For example, in an embodiment, as shown in FIG. 3, which is a schematic diagram of the training process of the present invention. In step 23, when the user executes the training step, it includes the detection information of step 230 for detecting that the user performs at least one inhalation or exhalation movement. In step 230, the detection information may be flow rate, heat, pressure, or any combination thereof. Information such as heat, pressure, or flow rate can be measured using sensors such as a respiratory fluid state sensor, for example, the aforementioned air pressure detection element 34, a heat sensor, or a flow meter. Next, step 231 is performed to determine whether the training reference information is satisfied according to the parameter information. In step 231, the arithmetic processing unit 32 calculates the actual respiration rate, exhalation / inhalation time, respiration volume, or flow rate according to the detection information, generates a target gap by comparing it with the training reference information, and the display unit guides and corrects the respiration movement according to the target gap. Then, it proceeds to step 232, and when the training reference information is reached, a prompt message is generated. The prompt message can be prompted by the display unit 320, an LED signal, a vibration element, or an acoustic element, and can guide the user through the training. Then steps 230 to 232 are repeated. When the user adapts to this inhalation volume target, the inhalation volume target can be gradually increased using step 22, that is, the inhalation resistance intensity can be gradually increased.

[0021] For example, in the present embodiment, taking FIG. 2B as an example, through the application installed in the arithmetic processing unit 32, the pressure information detected by the pneumatic pressure detection element 34 per unit time can be collected, and the application APP can calculate the integral value W of the pressure P(t) corresponding to time. Then, the integral value W is compared with the training reference information Ws. When the integral value W is equal to the training reference information Ws, that is, when the work W performed by the upper airway dilator muscle group 92 during the user's inspiration movement reaches the standard, the arithmetic processing unit generates a warning sound or message to prompt the user to rest and exhale, and the detected pneumatic pressure information, integral value information, etc. are simultaneously displayed on the display unit 320. Next, the next inspiration movement is repeated a specific number of times to achieve the effect of training the upper airway dilator muscle group.

[0022] Please refer to FIGS. 4 to 5, which are schematic diagrams of other embodiments of the training method for the respiratory muscle group of the present invention. In the embodiment of FIG. 4, basically it is the same as FIG. 1, but in this embodiment, it is different in that it further includes step 24 which is a step of adjusting the degree of training. In step 24, when the user adapts to this inspiration volume target, the training reference information gradually increases, that is, the inspiration resistance intensity gradually increases, so that the user can further strengthen the lung function. In the embodiment of FIG. 5, the process is basically the same as that of FIG. 1, but this embodiment further includes step 25, and observes the degree of decrease in the maximum inspiration volume or the number of times through at least one cycle of the inspiration movement, exhalation movement, or respiratory movement. In step 25, the user is instructed to inhale under resistance conditions, so that the upper airway shows a pressure drop or negative pressure state, and the diaphragm contracts to achieve the target inspiration volume. After one to several cycles, observe the degree of decrease in the target inspiration volume or the number of times to evaluate the user's lung function state.

[0023] Please refer to FIG. 6, which is a schematic diagram of one process of the training method for the respiratory muscle group in this invention. In this embodiment, first, step 20 is performed to provide a hood that covers the breathing area of the user's face. In this step, as shown in FIG. 2A, the hood body 30 in the figure is placed over the breathing area of the user 9's head, which may be the mouth, the nose, or both the mouth and the nose. The hood body 30 of this embodiment is a hood that covers the mouth and nose areas. An air flow adjustment element 31 is provided on the hood body 30, so that when the user inhales air, the intake amount of the air inhaled by the user from the external environment to the inside of the hood body 30 can be adjusted. In one embodiment, the hood body 30 is attached to the skin of the user's face and has an airtight effect. Also, since the hood body 30 can be buckled to the user's ears with an elastic belt, the hood body can be made to adhere closely to the user's face. In another embodiment, the hood body 30 can be replaced with a headpiece strap that is worn on the user's head, whereby the hood body 30 can be airtightly attached to the skin of the face. By pressing the skin airtightly, it can be ensured that air enters the hood body 30 from the air flow control element 31 and is then inhaled into the upper airway by the user's nose.

[0024] Returning to FIG. 1, following step 20, step 21 follows, controlling the distal or proximal airflow adjustment element to set and vary the intake resistance to simulate airway obstruction. In this step where negative pressure is generated in the airway relative to the external air pressure during the user's inhalation, as shown in FIG. 2A, the airflow adjustment element 31 has a control element 310 and can adjust the magnitude of the intake air volume according to a control signal. This magnitude represents the resistance when the user inhales. For example, when the valve opening degree of the airflow adjustment element 31 is large, the intake resistance is small. Thus, when the user inhales, the intake air volume entering the hood body 30 from the external environment through the airflow adjustment element 31 is large. Conversely, when the valve opening degree of the airflow adjustment element 31 is small, the intake resistance increases, so when the user inhales, the air taken into the hood body 30 from the external environment through the airflow adjustment element 31 decreases. In this embodiment, the control element 310 on the airflow adjustment element 31 can control the valve size of the airflow adjustment element 31 according to a control signal (for example, a Bluetooth signal or a wireless network signal that the remote unit can receive by wire or wirelessly, but this is not regarded as a limitation), and then control the resistance that needs to be overcome when the user inhales. Since the magnitude of this resistance is related to the training of the user's upper airway muscle group, by appropriately controlling the resistance or its variation, the effect of training the user's upper airway muscle group can be achieved.

[0025] In the embodiment of step 21, the user is connected to the control element 310 of the airflow adjustment element 31 through the arithmetic processing unit 32. In one embodiment, the arithmetic processing unit 32 may be an intelligent handheld unit or a wearable unit, such as a smartphone, a tablet computer, or a wearable watch, or a unit combining the hood body 30 and the airflow adjustment element 31. Also, the arithmetic processing unit 32 may be a notebook computer, a cloud server, etc. In this embodiment, the arithmetic processing unit 32 is a smartphone equipped with a display unit 320. The arithmetic processing unit 32 executes the application APP, and after the user executes it, a user interface is displayed on the display unit 320. In one embodiment, the user interface has a function option that can be automatically or manually electrically connected to the airflow adjustment element 31, for example, a signal connection such as Bluetooth, a radio frequency signal, or a wireless signal. After the signal connection, the user can control the valve size of the airflow adjustment element 31 through the user interface displayed by the display unit 320, set and change the intake resistance for simulating airway obstruction, and generate a negative pressure in the airway when the user inhales.

[0026] Thereafter, step 22 is performed to measure physiological parameters related to the user's respiratory movement state during the user's breathing process. In this step, the physiological parameters are blood oxygen concentration, heart rate pulse, physiological potential, respiratory flow, respiratory pressure, abdominal circumference, chest circumference, respiratory sound (for example, thoracic respiration, palatal respiration, or laryngeal airflow sound), or a combination of at least two of the above. The purpose of this step is to observe and judge the effect of the user's upper airway muscle training. Since the training of muscle groups cannot be directly visualized, the purpose of this step is to judge by physiological parameters. For example, in an embodiment, as shown in FIG. 7, FIG. 7(a) represents the arithmetic processing unit 32 that sends a control signal from a remote end to the airflow adjustment element 31. FIG. 7(b) represents the change in resistance when the user inhales. FIG. 7(c) represents the change in the inhalation / exhalation cycle. FIG. 7(d) represents the change in the pressure curve of the upper airway. FIG. 7(e) represents the change curve of the blood oxygen concentration.

[0027] In FIG. 7, the arithmetic processing unit 32 transmits control signals at three time points such as T1, T2, and T3, which are used to control the intake air volume of the air flow adjustment element 31 and represent the resistance when the user inhales. For example, at time T1, the resistance decreases, indicating an increase in the valve opening degree of the air flow adjustment element 31, and the flow rate of the air inhaled by the user also increases. At time point T2, since the resistance increases, it indicates a decrease in the valve opening degree of the air flow adjustment element 31, and the flow rate of the air inhaled by the user also decreases. As shown in FIGS. 7(c) to 7(d), taking time point T2 as an example, since the intake air volume per unit time during the inhalation process decreases, the respiratory cycle time extends. At the same time, as shown in region A of FIG. 7, the pressure in the upper airway drops to a negative pressure. At the same time, as seen in region B of FIG. 7(e), the blood oxygen also decreases. By inducing the user to strengthen the inhalation cycle, the blood oxygen can be increased again. Therefore, through at least one of the above physiological parameters, the change in the user's respiratory state due to the change in the intake air volume of the air flow adjustment element 31 can be correlated. Therefore, as long as the physiological parameters are known during the user's training, they can be used to guide the user to train the upper airway muscles.

[0028] As shown in FIG. 2A, physiological parameters can be measured by the physiological parameter detection element 33, and the physiological parameter detection element 33 changes according to the detected parameters and is not restricted by being arranged on the hood body 30. For example, the blood oxygen concentration can be measured by a blood oxygen sensor attached to the user's finger. By attaching an electrode to the user's skin for physiological potential, the electrocardiogram parameters of the user during breathing can be obtained. The respiratory flow rate or pressure can be measured by providing an airflow characteristic detection element such as a flow meter, a pressure meter, or a combination of the two on the hood worn by the user, and the pressure in the user's airway and the intake or exhalation flow rate can be measured. Changes around the waist or bust can be detected by detecting changes in length with a chest strap or belt set on the user's chest or waist. In another embodiment, as shown in FIG. 2G, in this embodiment, it is connected to the hood body 30 via a pipeline 330, and then the air pressure or flow rate is detected using the physiological parameter detection element 33. Here, the physiological parameter detection element 33 of this embodiment is a pressure sensor or a flow sensor. Since the above physiological parameters change when the user inhales / exhales, the measured information can be used as the basis for subsequent training adjustment.

[0029] In another embodiment, the physiological parameter detection element 33 can be used to measure and observe the state of the respiratory muscles by an image or an audio signal, and then the movement state (muscle strength and muscle endurance) of the muscles can be evaluated. The physiological parameter detection element 33 can be classified into contact type and non-contact type. (1) Contact type: Mechanomyography (MMG) of muscle sound uses a piezoelectric chip to measure the vibration frequency on the muscle surface and measures the degree of muscle contraction. Also, the changes in muscles can be directly observed using the M-mode and B-mode of ultrasonic waves. (2) Non-contact: Observe the hot spots of muscle contraction by thermal imaging technology, observe the changes in the appearance of the soft palate using a CCD camera, such as changes in the shape and angle of the palatopharyngeal arch, or perform direct observation by 3D stereo imaging.

[0030] Next, step 23 is executed. In this process, the training mode can be adjusted according to physiological parameters. In this step, mainly determine the user's training mode through the changes in physiological parameters sensed in the previous step 22 to achieve the training effect. The training mode is to breathe according to the changes in a specific frequency, depth, length of time, or pressure difference, or to breathe according to a training cycle composed of a specific number of inhalation times and a specific number of exhalation times, depth, or pressure difference. For example, inhalation, inhalation, exhalation or inhalation, exhalation, exhalation, etc. are not limited. Figure 7(c) is a schematic diagram of the curve of the breathing motion.

[0031] In one embodiment, as shown in Figure 8, increase the inhalation resistance through remote control at T1 (as shown in Figures 8(a) - (b)). Under this set condition, the user breathes according to the changes in a specific frequency, depth or pressure difference, and measures the physiological parameters related to the user's breathing state through the aforementioned physiological parameter detection element 33. The physiological parameters in this embodiment are the respiratory rate (Figure 8(c)), blood pressure (Figure 8(d)), and blood oxygen concentration (Figure 8(e)). The obtained physiological parameters are transmitted to the remote computing unit 32 by transmission. After receiving the measured physiological parameters, the computing unit 32 makes a judgment according to the reference physiological parameters stored in the database in advance, and then determines whether to adjust the inhalation resistance according to the reference physiological parameters and physiological parameters during breathing corresponding to the changes in a specific frequency, depth, or pressure difference. For example, at the time point T2 shown in Figure 8(a), the user reduces the resistance and increases the intake air flow rate.

[0032] In the mode of adjusting the intake resistance, the user can control the flow or the increase or decrease of the resistance of the air when inhaling by the airflow adjustment element 31 on the hood body 30 in the vicinity or remotely. The greater the resistance when the user inhales, the less the air in the external environment enters the user's nasal cavity through the airflow adjustment element 31. Therefore, the pressure in the upper airway decreases, generating the effect of negative pressure in the upper airway. As shown in FIG. 9A, the user 9 has set the intake resistance of the airflow adjustment element 31. Under the condition of having resistance, when the user performs an inhalation movement, the diaphragm 90 contracts and extends outward, causing a pressure drop in the airway 91, for example, generating an atmospheric pressure or negative pressure lower than the environment where the user is located. The following will be described with the negative pressure P0. When the negative pressure P0 is generated in the airway 91, due to the pressure generated by the negative pressure, the upper airway dilator muscle group 92 is stretched into the airway, preventing the smooth passage of the airway.

[0033] At this time, the nervous system in the user's body acts to contract the upper airway dilator muscle group 92 to keep the respiratory passage open and avoid the negative pressure that causes the upper airway dilator muscle group to collapse. When the user exhales, as shown in FIG. 9B, the diaphragm 90 of the user 9 expands and returns in the opposite direction. At this time, the airway 91 returns to the positive pressure P1, and then the upper airway dilator muscle group 92 no longer stretches due to the negative pressure for negative pressure release. Through the repeated movements of inhalation and exhalation, the upper airway dilator muscles are contracted and expanded to exercise the upper airway muscle group. In one embodiment, the upper airway muscle group 92 also includes the soft palate muscle 92a.

[0034] Under the action of the inhalation / exhalation cycle, the flowmeter in the physiological parameter detection element 33 can monitor the change in the frequency of air exchange during the cycle (as shown in FIG. 8(b)), and the blood oxygen concentration sensor in the physiological parameter detection element 33 can monitor the change in the oxygen concentration during the period (as shown in FIG. 8(e)). After these physiological parameters are transmitted to the arithmetic processing unit 32, the arithmetic processing unit 32 compares the above information with the training reference information, and then determines whether to adjust the resistance to the air intake through the airflow adjustment element 31.

[0035] In one embodiment, the arithmetic processing unit 32 is provided with a prompt device for providing display signals of sound, color, vibration, or touch. The prompt device is an LED, a display, a buzzer, a speaker, or a vibrator, and can generate information regarding the process of the training target. In this embodiment, the prompt device is the display unit 320, for example, a display screen. The display message generated by the prompt device can guide the user to perform a breathing action to exercise the upper airway muscle group. In another embodiment, the arithmetic processing unit 32 and the display unit 320 may be independent devices arranged externally, or may be combined with the hood body 30, which is determined according to the usage requirements and has no certain restrictions.

[0036] In summary, the present invention can actually achieve the desired functions and purposes, and those skilled in the art can implement it based on the above detailed description. Therefore, from the above embodiments, changes in equivalent structures still do not deviate from the scope of the rights of the present invention. That is, changes or modifications made in the same creative spirit related to the present invention should be included in the protection scope of the present invention.
