[0055] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in the embodiments may be combined with each other.

[0056] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or component referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as limiting the present invention. In addition, the terms "first", "second", and the like are only used for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of technical features indicated. Thus, features defined as "first", "second", and the like may explicitly or implicitly include one or more features. In the description of the present invention, unless otherwise specified, "multiple" means two or more.

[0057] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or a specific connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0058] The specific embodiments of the present invention are described in detail below with reference to the accompanying drawings.

[0059] like Figure 1-Figure 7 As shown, the present invention proposes a training quantification method for a respiratory trainer, which is based on the following fact: by setting an adjustable resistance in the airway, when the size of the adjustable resistance is much larger than the inherent flow resistance of the anatomical dead space of the human airway, the inherent flow resistance can be ignored, and the oral pressure and the intrapulmonary pressure are basically equal. By measuring the flow rate and oral pressure of the two phases of breathing during human respiratory training / pulmonary muscle training, it can be used to accurately describe the effect of the respiratory muscles. The human respiratory system can be approximated as a pipeline system with one end open, and the breathing process can be simplified as the process of the respiratory muscles doing work on the gas in the tube. The resistance load type respiratory trainer achieves the purpose of respiratory muscle strength and endurance training by setting an adjustable flow blocker in the respiratory passage, and the respiratory muscles overcome the resistance of the fluid flow blocker to do work on the gas. The adjustable flow blocker can be set within a certain range according to the training intensity and purpose.

[0060] Specifically, the breathing training device involved in the training method of the present invention includes a flow blocker, and the flow blocker can adjust the resistance by adjusting the effective pass area of ​​the fluid. In some embodiments, the training method of the present invention includes the following steps:

[0061] S1, obtaining the pressure difference ΔP between the air outlet port and the air inlet port of the flow blocker and the flow rate Q passing through the flow blocker, and establishing a PQ flow resistance load curve R according to the pressure difference ΔP and the flow rate Q, wherein the PQ flow resistance load curve R is related to the effective let-through area of ​​the flow blocker;

[0062] S2. According to different effective let-through areas A1...Ak...Ai, respectively establish PQ flow resistance load curves R1...Rk...Ri in the same coordinate system;

[0063] S3, based on the PQ flow resistance load curve R1...Rk...Ri, obtain the resistance F1...Fk...Fi corresponding to the flow blocking element at different effective let-through areas A1...Ak...Ai, different pressure differences ΔP or different flow rates Q;

[0064] S4. The above parameters and / or curves are displayed during breathing training to achieve comprehensive quantification of breathing training parameters and process.

[0065] Further, in some embodiments, the step “S1” of “obtaining the pressure difference ΔP between the air outlet port and the air inlet port of the baffle and the flow rate Q passing through the baffle” includes the following steps:

[0066] S11, respectively setting pressure sensors at the outlet port and the inlet port, and calculating the pressure difference ΔP between the outlet port and the inlet port by the difference between the two pressure sensors;

[0067] S12, according to the relationship between pressure difference ΔP and flow rate Q In the two directions of "two phases of breathing", the flow rate Q is taken from zero to large, and the expiratory phase PQ flow resistance load curve R and the inspiratory phase PQ flow resistance load curve R are established respectively.

[0068] It should be noted that the above formula In, C is the fluid coefficient, which varies according to different flow-blocking parts and can be determined by experiments, A is the effective area that allows the fluid to pass through the flow-blocking part, and ρ is the density of the fluid. Further, in some embodiments, the measurement of the pressure difference ΔP in the above step S11 can also be achieved in the following way: by setting two pressure points at the outlet port and the inlet port, respectively, and leading the two pressure points to a differential pressure sensor, and completing the measurement of ΔP through the differential pressure sensor. In addition, preferably, the measurement of the pressure difference ΔP can also be achieved by setting only one pressure sensor at the inlet port. Specifically, when the product is implemented, because the flow rate is zero in the power-on stage (zero flow), the pressure difference is zero at this time. At this time, the local atmospheric pressure can be measured by the sensor and memorized in the memory, because in one or more measurements, the local atmospheric pressure value is stable and unchanged, and only the oral pressure needs to be measured later. In order to realize a sensor to indirectly obtain the pressure of two points and calculate ΔP, it can be understood that through the above steps, the setting of the second pressure point or the second pressure sensor can be omitted, the structure is simple, and the cost is saved.

[0069] Furthermore, in some embodiments, step "S2" may select a smaller effective allowable area of ​​the obstruction piece according to the different requirements for respiratory muscle training in sports health and airway disease rehabilitation, for large respiratory muscle strength and long endurance training, and for small respiratory muscle strength and short endurance training, for a larger effective allowable area of ​​the obstruction piece.

[0070] Specifically, a series of effective let-through areas of the flow-blocking components can be selected, namely A1, A2, A3, A4, A5, A6... The effective let-through area A of the above-mentioned flow-blocking components is taken from zero to large according to the two directions of "breathing two phases" and the flow rate Q, and the relationship is The ΔP value corresponding to a certain Q value can be obtained, with the pressure difference ΔP as the y-axis. Considering that the median values ​​of the maximum oral pressure when humans hold their breath and make the greatest effort to exhale and inhale are about +10kPa and -10kPa respectively, the measurement range can be expanded to more than ±20kPa through the Q test value to cover extreme cases. At the same time, ±20kPa is used as the value limit. When this value is reached, the test value of Q will no longer increase. The flow rate Q is used as the x-axis.

[0071] During the exhalation phase, the oral pressure (intrapulmonary pressure) is positive pressure, and the minimum effective allowable area A1 of the flow blocker is selected. Since the pressure value and flow value at this time are both ≥ 0, the drawn curve is in the first quadrant. Through the continuous value test of the flow value Q, we get Figure 1 The leftmost curve A1 (green) is the flow resistance load curve R1. By selecting different effective let-through areas A1, A2, A3, A4, A5, A6, etc. of the flow blocker, a series of curves in the first quadrant can be obtained. The larger the effective let-through area, the more to the right the curve is.

[0072] Similarly, during the inhalation phase, the oral pressure (intrapulmonary pressure) is negative, and the minimum effective allowable area A1 of the flow blocker is selected. Since the pressure value at this time is ≤0, the flow value is positive, so the drawn curve is in the fourth quadrant. Through the continuous value test of the flow Q, we get Figure 2 The leftmost curve A1 (green) is the flow resistance load curve R1 of the suction phase. By selecting different effective let-through areas A1, A2, A3, A4, A5, A6... of the flow-blocking element, a series of curves in the fourth quadrant can be obtained. The larger the effective let-through area, the more to the right the curve position.

[0073] Through the above steps, the user can select the impedance load curve Rk that suits him / her for use in exercising the respiratory muscles. In a breathing training cycle, the power point factor of the user's respiratory muscles will move on the impedance curve currently selected in the first or fourth quadrant.

[0074] Further, in some embodiments, the step "S3" of "obtaining the resistance F1...Fk...Fi corresponding to the flow blocker at different effective let-through areas A1...Ak...Ai at different pressure differences ΔP or different flow rates Q based on the PQ flow resistance load curve R1...Rk...Ri" includes the following steps: calculating the resistance F1...Fk...Fi respectively according to the formula F=ΔP / Q. Based on the above principle, the user can select a certain impedance load curve Rk, and during breathing training, the resistance Fk of the current breathing training can be displayed in real time according to the current pressure difference or flow rate.

[0075] Furthermore, in some embodiments, the training method further comprises the following steps:

[0076] S41, selecting an effective let-through area Ak;

[0077] S42, in a coordinate system, respectively establish a "pressure difference ΔP-Ak resistance load" curve and a "flow rate Q-Ak resistance load" curve during training, wherein time T is the x-axis, pressure difference ΔP is the first y-axis, and flow rate Q is the second y-axis;

[0078] S43, establishing a "respiratory muscle work-Ak resistance load" curve during training, wherein time T is the x-axis and the power W of the respiratory muscle work is the y-axis, wherein power W=ΔP*Q;

[0079] S44. In a coordinate system, the flow rate Q is taken from zero to large, and a PQ flow resistance load curve Rk and an impedance curve Fk are established respectively, wherein the flow rate Q is the x-axis, the pressure difference ΔP is the first y-axis, and the resistance Fk is the second y-axis;

[0080] S45. Display the above-mentioned “pressure difference ΔP-Ak resistance load” curve and / or “flow Q-Ak resistance load” curve and / or “respiratory muscle work-Ak resistance load” curve and / or PQ flow resistance load curve Rk and / or impedance curve Fk.

[0081] It can be understood that based on step "S42", such as Figure 3 , red represents the flow curve, blue represents the pressure curve, at time 0, the pressure of the blue curve is 0, and the flow of the red curve is 0. Based on the above curves, the user can observe the changes of flow and pressure over time during training in real time. Similarly, based on step "S43", Figure 4 , users can observe in real time the changes in the work done by the respiratory muscles during training over time, based on "S44", such as Figure 5 , users can observe in real time the changes in pressure and resistance with flow during training.

[0082] Further, in some embodiments, the breathing training includes a normal training mode, a constant pressure training mode, a constant flow training mode, and a constant power training mode.

[0083] Further, in some embodiments, the general training mode includes the following steps:

[0084] Select an effective let-through area Ak according to the requirements;

[0085] When the effective let-through area Ak remains unchanged, use a breathing trainer to perform exhalation training and / or inhalation training;

[0086] The current training pressure difference ΔP and / or flow Q and / or resistance F and / or power W of the respiratory muscles are displayed in real time to achieve comprehensive quantification of respiratory training parameters and process quantification, where power W = ΔP*Q.

[0087] Based on the above steps, the user can set the effective let-through area of ​​the baffle to an appropriate value according to the purpose or need of breathing training. During breathing training, the effective let-through area of ​​the breathing trainer or lung muscle trainer remains unchanged. A smaller effective let-through area can obtain a larger oral pressure, which can achieve greater respiratory muscle strength and more lasting respiratory muscle endurance training, while a larger effective let-through area has the opposite effect.

[0088] Further, in some embodiments, the constant pressure training mode includes the following steps:

[0089] Set the oral pressure value for breathing training;

[0090] Real-time monitoring of the pressure difference ΔP during breathing training;

[0091] When the measured pressure difference ΔP is higher than the oral pressure range, the effective let-through area A is increased accordingly to reduce the pressure difference ΔP to make it fall within the set oral pressure range;

[0092] When the measured pressure difference ΔP is lower than the oral pressure value range, the effective let-through area A is correspondingly reduced to increase the pressure difference ΔP so that it falls within the set oral pressure value range;

[0093] The current training pressure difference ΔP and / or flow Q and / or resistance F and / or power W of the respiratory muscles are displayed in real time to achieve comprehensive quantification of respiratory training parameters and process quantification, where power W = ΔP*Q.

[0094] Based on the above steps, the user can set the oral pressure value of breathing training within a certain range. During a breathing training process, when the measured value is larger (smaller) than the set value, the effective pass area can be increased (reduced), and the oral pressure of the two phases of breathing can be kept stable through real-time adjustment of the baffle.

[0095] Further, in some embodiments, the constant flow training mode includes the following steps:

[0096] Set the flow value for breathing training;

[0097] Real-time monitoring of flow rate Q during breathing training;

[0098] When the measured flow rate Q is higher than the flow value range, the effective let-through area A is correspondingly reduced to reduce the pressure difference ΔP to make it fall within the set flow value range;

[0099] When the measured pressure difference flow rate Q is lower than the oral pressure value range, the effective let-through area A is increased accordingly to increase the flow rate Q to make it fall within the set flow value range;

[0100] The current training pressure difference ΔP and / or flow Q and / or resistance F and / or power W of the respiratory muscles are displayed in real time to achieve comprehensive quantification of respiratory training parameters and process quantification, where power W = ΔP*Q.

[0101] Based on the above steps, the user can set the flow value of breathing training within a certain range. During a breathing training process, when the measured value is larger (smaller) than the set value, the effective pass area can be reduced (increased), and the two-phase flow of breathing can be kept stable through real-time adjustment of the flow blocker.

[0102] Further, in some embodiments, the constant power training mode includes the following steps:

[0103] Create a constant power lookup table: The left side of the query table equal sign is "a set of constant power values ​​that can be set", and the right side of the query table equal sign is "a number of effective let-through areas A and flow rates Q that can correspond to a certain set constant power";

[0104] Set the power value for breathing training;

[0105] Get the effective let-through area A and flow rate Q during the current training, and calculate the current work value;

[0106] If the current work value deviates from the set power value, it will be adjusted accordingly according to the constant power query table;

[0107] The current training pressure difference ΔP and / or flow Q and / or resistance F and / or power W of the respiratory muscles are displayed in real time to achieve comprehensive quantification of respiratory training parameters and process quantification, where power W = ΔP*Q.

[0108] Furthermore, “establishing a constant power query table” includes the following steps:

[0109] According to different effective let-through areas A1...Ak...Ai, power curves P1...Pk...Pi are established in the same coordinate system, where the y-axis is the power axis and the x-axis is the flow axis;

[0110] Take the y-axis from small to large values ​​and establish a series of power lines parallel to the x-axis and intersecting the power curve;

[0111] Record the power value corresponding to the current power line, the flow value at the intersection of the power line and each power curve, and the effective let-through area. Repeat the above steps for different power lines to establish a "constant power query table".

[0112] It can be understood that through the above steps, Figure 6 In the constant power training mode, the y-axis can be the power axis and the x-axis can be the flow axis. According to different effective pass areas A1...Ak...Ai, power curves P1...Pk...Pi are established in the same coordinate system. Figure 6From the trend, we can know that a smaller effective let-through area can only obtain a smaller power value, even if the oral pressure reaches the upper limit of human breathing effort; while a larger effective let-through area can obtain a larger power value. According to the different ranges of the effective working area, the constant power value depends on the corresponding intersection of the power curve family and the flow value specified by the effective let-through area. By taking the power from small to large on the entire plane, a series of parallel power lines can be obtained. The x and y coordinates of a power line depend on the flow point corresponding to the power curve and the x-axis, that is, when the effective let-through area and the flow value are determined, the power value is determined. P1: (A1, Q11), (A2, Q12), (A3, Q13), (A4, Q14), (A5, Q15), (A6, Q16), (A..., Q...), P2: (A1, Q21), (A2, Q22), (A3, Q23), (A4, Q24), (A5, Q25), (A6, Q26), (A..., Q...), ... Thus, a two-dimensional matrix is ​​obtained. Once the power is set, the breathing movement can be controlled to move left and right on the line composed of the above points to perform constant power respiratory muscle group training. The control method of constant power (constant load) is as follows:

[0113] When the user sets the breathing trainer to run at a certain constant exercise power value, the current flow value can be obtained. The current actual power point can be obtained based on the effective let-through area power curve specified at the current position and the current flow value. When the actual power point deviates from the set power value, the corresponding flow rate and effective let-through area can be adjusted based on the established constant power lookup table to continuously reduce the error between the current power and the set power, thereby completing the adjustment of the power value. When the target power value is set too large and the target value cannot be met by the table lookup algorithm, the device prompts the user to increase the effort of breathing training or adjust the power target value.

[0114] Furthermore, the present invention also provides a flow-blocking device that can be used for the breathing trainer of the present invention, the flow-blocking device includes an air inlet port 1 and an air outlet port 2, an adjustment seat 4 is provided at the connection between the air inlet port 1 and the air outlet port 2 for adjusting the resistance, the adjustment seat 4 includes a connecting port 41, an adjustment member 5 is provided at the connecting port 41, and the adjustment member 5 can move relative to the connecting port 41 to adjust the effective flow area of ​​the flow-blocking device.

[0115] Furthermore, in some embodiments, the adjusting member 5 can be an adjustable core rod, which is arranged in a cone shape at the connecting port 41, and the shape of the connecting port 41 matches the adjusting seat 4. When the adjustable core rod moves forward and backward relative to the connecting port 41, the matching clearance between the adjustable core rod and the connecting port 41 increases or decreases to achieve the adjustment of the effective pass area.

[0116] Furthermore, in some embodiments, the baffle further includes a driving unit 3 , which may be a motor. The driving unit 3 is connected to the adjusting unit 5 to drive the adjustable core rod to move.

[0118] Furthermore, in some embodiments, the breathing trainer also includes a program memory, in which a normal training mode, a constant pressure training mode, a constant flow training mode and a constant power training mode can be preset. The program memory cooperates with a microprocessor, a position sensor and a baffle to form a closed-loop control system for automatic adjustment.

[0119] For example, in the constant power training mode, the program can obtain the current actual power point by obtaining the current position and current flow value of the adjustable core rod, the effective let-through area power curve specified by the current position and the current flow value. When the actual power point deviates from the set power value, the program can drive the adjustable core rod to move left or right according to the shortest distance principle and the predicted trend of respiratory movement based on the table lookup algorithm. The so-called shortest distance principle means that the target power point moved by the current power point has the shortest distance through the core rod. The predicted trend of respiratory movement refers to the change trend of flow and pressure in the initial stage, middle stage and end stage of breathing or inhalation determined by human physiology. Generally, a smaller power setting value can always be achieved by reducing the effective let-through area (reducing flow). By obtaining the current effective let-through area value and flow value in real time, comparing them with the set (target) effective let-through area and flow value, the error between the two is continuously reduced through the table lookup algorithm, thereby completing the adjustment of the power value; when the target power value is set too large and the target value cannot be met through the table lookup algorithm, the device prompts the user to increase the effort of breathing training or adjust the power target value.

[0120] In summary, the training quantification method, flow-blocking component and breathing trainer proposed in the present invention have the following beneficial effects compared with existing products on the market: first, comprehensive quantification of breathing training parameters. Currently, existing products are not sufficient to evaluate the effect and purpose of breathing training by only measuring oral pressure or vital capacity; second, process quantification. All fluid mechanics parameters with the cardiopulmonary-respiratory muscle group as the source power during breathing training are fully recorded and displayed in intuitive and simple charts. That is, the present invention is intuitive, clear and clear in the process evaluation and target effect confirmation of breathing training, which solves the technical problem of large blindness and uncertainty in existing breathing training on the market.
