Embodiment 1

Please refer to Figure 1, which is a visual method for testing respiratory muscle strength provided by an embodiment of the present invention, including the following steps S101-S103:

Step S101: Display an initial image frame on the display screen, and in response to the user's exhalation of the mouthpiece device, obtain the user's exhalation pressure in real time through a pressure sensor.

As a preferred solution of this embodiment, before displaying the initial image frame on the display screen, it also includes:

In response to the test level selected by the user, a preset expiratory pressure gradient range is obtained according to the test level; wherein each test level corresponds to a preset expiratory pressure gradient range, and the expiratory pressure gradient range includes several expiratory pressure gradient.

In this embodiment, a grade coefficient corresponding to each test level is pre-stored in the terminal device for testing respiratory muscle strength, and the preset expiratory pressure gradient range can be determined by the user-selected grade coefficient and unit expiratory pressure gradient. obtained by multiplying the ranges; where, the unit expiratory pressure gradient range represents the range covered by each gradient under the initial unit pressure; for example, the unit expiratory pressure gradient range includes a, b, c and d Four gradients, where a is 0-5mmHg, b is 5-10mmHg, c is 10-15mmHg, and d is 15-20mmHg. For example, there are three test levels that the user can select, that is, corresponding to 1kg pressure, 5kg pressure and 10kg pressure. When the user selects 5kg pressure, that is, the level coefficient is 5, then the unit expiration pressure gradient range and Multiply the grade coefficients to obtain the preset expiratory pressure gradient range (including four gradient ranges A, B, C and D), where A=(0-5mmhg)*5, B=(5-10mmHg)*5, C=(10-15mmHg)*5, D=(15-20mmHg)*5.

As another example, the unit expiratory pressure gradient range includes N gradients, then the preset expiratory pressure gradient range corresponding to the first gradient to the Nth gradient can be obtained through the user-selectable test levels.

As a preferred solution of this embodiment, the initial image frame is displayed on the display screen, and in response to the user's exhalation of the mouthpiece device, the user's exhalation pressure is obtained in real time through a pressure sensor, specifically including:

According to the number of exhalation pressure gradients, the number of display image frames of the preset animation is determined, so that the initial image frame of the preset animation is displayed on the display screen; in response to the user's exhalation of the mouthpiece device, the pressure sensor is used in real time to Obtain the user's expiratory pressure, and record the time corresponding to the user's expiratory pressure through a clock.

In this embodiment, for example, there are four exhalation pressure gradients A, B, C and D, so the number of display image frames of the preset animation is also four, so that the first image of the preset animation is frame as the initial image frame displayed on the display. By responding to the user's exhalation of the mouthpiece device, the user's exhalation pressure can be accurately obtained in real time through the pressure sensor, and the time and/or moment corresponding to the user's exhalation pressure can be recorded through the clock, so that the user can be monitored Accurately and completely record the expiratory pressure and other data.

Step S102: Determine the expiratory pressure gradient where the current expiratory pressure is based on the preset expiratory pressure gradient range, and obtain a display image frame corresponding to the current expiratory pressure gradient; wherein, each expiratory pressure gradient corresponds to Image frames are displayed, and each expiratory pressure gradient represents a sub-range of the preset expiratory pressure gradient range.

As a preferred solution of this embodiment, determining the expiratory pressure gradient where the current expiratory pressure is based on the preset expiratory pressure gradient range, and obtaining a display image frame corresponding to the current expiratory pressure gradient, specifically includes:

Determine the current real-time expiratory pressure and the corresponding expiratory pressure gradient in the preset expiratory pressure gradient range; wherein, each expiratory pressure gradient in the preset expiratory pressure gradient range is sorted from small to large; The sorting of each expiratory pressure gradient establishes an index relationship with the display image frame of the preset animation, thereby obtaining the final display image frame corresponding to the expiratory pressure gradient where the current real-time expiratory pressure is located; wherein, the preset animation The number of displayed image frames of the animation is the same as the number of said expiratory pressure gradients.

In this embodiment, after determining the current real-time expiratory pressure, the corresponding expiratory pressure gradient is selected from the preset expiratory pressure gradient range. For example, the preset expiratory pressure gradient range (including A, Four gradient ranges of B, C and D), among which, A=(0-5mmhg)*5, B=(5-10mmHg)*5, C=(10-15mmHg)*5, D=(15-20mmHg) *5 is an example. When the current real-time expiratory pressure is 36mmhg, select expiratory pressure gradient B. Further, an index relationship is established between the sorting of each expiratory pressure gradient and the display image frame of the preset animation. At the same time, since each expiratory pressure gradient in the preset expiratory pressure gradient range is sorted from small to large, the preset Assume that the animation displays the image frames in sequence as they are played, and establishes an index relationship with the expiratory pressure gradient, that is, the expiratory pressure gradient A corresponds to the first image frame, the expiratory pressure gradient B corresponds to the second image frame, and the expiratory pressure gradient Gradient C corresponds to the third image frame, and expiratory pressure gradient D corresponds to the fourth image frame.

In this embodiment, after establishing the index correspondence between the display image frame and the expiratory pressure gradient, the expiratory pressure gradient corresponding to the current real-time expiratory pressure can be used to determine the expiratory pressure gradient. The image frame is displayed, which is then used as the final displayed image frame corresponding to the current real-time expiratory pressure team.

Step S103: Update the initial image frame in the display screen to the display image frame corresponding to the current respiratory measurement gradient, thereby realizing the visualization of the test of respiratory muscle strength.

As a preferred solution of this embodiment, updating the initial image frame in the display screen to a display image frame corresponding to the current respiratory measurement gradient specifically includes:

According to the sorting position of the current expiratory pressure gradient in the preset expiratory pressure gradient range, all expiratory pressure gradients before the current expiratory pressure gradient sorting position and their corresponding display image frames are obtained as a set of image frames to be displayed; where , each display image frame in the set of image frames to be displayed is sorted from small to large according to its corresponding exhalation pressure gradient; in response to the user exhaling on the mouthpiece device, after each delay of the preset time, according to the The sequence of each display image frame in the set of image frames to be displayed is sequentially updated and displayed on the display screen until all display image frames in the set of image frames to be displayed are updated. After one pass, the display screen is finally updated to the final display image frame.

In this embodiment, through the sorting position of the current expiratory pressure gradient in the preset expiratory pressure gradient range, all expiratory pressure gradients before the current expiratory pressure gradient sorting position and their corresponding display image frames can be obtained. For example, taking the preset expiratory pressure gradient range (including four gradient ranges A, B, C and D) and the current expiratory pressure as 60mmhg, that is, the current expiratory pressure gradient is C, through the current expiratory pressure gradient range The sorting position of the air pressure gradient in the preset expiratory pressure gradient range, that is, the third position, corresponding to the third image frame is the final image frame, and all expiratory pressure gradients (A) before the current expiratory pressure gradient sorting position can be obtained and B) and their corresponding display image frames (the first image frame and the second image frame), thereby updating the initial image frame to the first image frame after a preset time delay in response to the user exhaling on the mouthpiece device. An image frame; after changing to the first image frame, and then delaying the preset time, the first image frame is updated to the second image frame; after changing to the second image frame, and then delaying the preset time, due to all Both the first image frame and the second image frame in the set of image frames to be displayed have been displayed, so the second image frame is updated to the third image frame, that is, the final image frame, thereby completing the visualization of expiratory pressure. It should be noted that the preset time can be determined according to actual measurement requirements. Preferably, the preset time is 500 microseconds.

As a preferred solution of this embodiment, before updating the display image frame corresponding to the current respiratory measurement gradient, it also includes:

According to the time corresponding to the user's real-time expiratory pressure, the duration of maintaining the expiratory pressure gradient corresponding to the real-time expiratory pressure is calculated; when the duration is greater than or equal to the preset holding time, update is the display image frame corresponding to the current respiratory measurement gradient; when the duration is less than the preset holding time, the system keeps waiting and continues to obtain the user's real-time expiratory pressure.

In this embodiment, through the time and/or moment corresponding to the user's real-time expiratory pressure, the expiratory pressure gradient corresponding to the current real-time expiratory pressure can be calculated, and the time maintained is used as the duration. Since the pressure in the entire process of human exhalation first goes from low to high and then to low again, during the process of pressure increase or decrease, the real-time exhalation pressure covered by the expiration pressure gradient can be used to correspond to the time, that is, The corresponding duration of the expiratory pressure gradient can be calculated.

Furthermore, when the duration is greater than or equal to the preset holding time, it means that the expiratory pressure gradient is not a process of increasing or decreasing the expiratory pressure, but that the user has maintained the expiratory pressure at the current level. The expiratory pressure gradient can be understood as the maximum value (or maximum value) of the user's expiratory pressure, so the preset animation is frozen at the current display image frame corresponding to the expiratory pressure gradient, and then updated to the display screen. When the duration is less than the preset holding time, it means that the expiratory pressure gradient is a process of increasing or decreasing the expiratory pressure, so the expiratory pressure will continue to increase or decrease, that is, the expiratory pressure has not yet been reached. The maximum value (or maximum value) of the pressure is displayed, and the expiratory pressure gradient will also change, so that the corresponding final image frame cannot be determined, thereby improving the accuracy of the image frame display, and at the same time, it can Achieve smooth playback of preset animations, reduce the large delay between expiratory pressure and animation display, and improve the reliability and accuracy of visual display of respiratory pressure.

As a preferred solution of this embodiment, it also includes:

According to the time corresponding to the user's real-time exhalation pressure, the duration of the entire exhalation process of the user and the expiration pressure corresponding to each moment during the duration are obtained; according to the time corresponding to the entire exhalation process The duration and the expiratory pressure corresponding to each moment are used to generate an expiratory pressure versus time graph; in response to the user's click operation on the display screen, the expiratory pressure versus time graph is displayed.

In this embodiment, based on the time corresponding to the user's real-time exhalation pressure, the duration of the entire exhalation process by the user and the corresponding exhalation pressure at each moment during the duration are obtained, and then To generate the corresponding expiratory pressure versus time graph. After finishing the respiratory strength training test, the user can click on the display screen to display the relationship between exhalation pressure and time, thus allowing the user to accurately obtain the data of the complete process, and the doctor or medical institution can also update With this complete respiratory pressure data, more detailed rehabilitation plans can be formulated for users or patients, thereby improving the user experience.

In this embodiment, please refer to Figures 2 and 3, which are equipment and page displays for connecting a mouthpiece device and a mobile phone to experience a breathing weight lifting game provided by an embodiment of the present invention. The preset animation used in the respiratory muscle test is Weightlifting animation, see Figure 4, which is a flowchart of the breathing weightlifting game, showing how the game animation or animation frame responds to the air pressure signal generated by the mouthpiece connected to the smartphone. Multiple weight lifting options are available in this game from 10kg to N x10kg. There are two main parameters that control the weight lifting in the game animation, namely the air pressure P generated by the mouthpiece, and the time m for the user to maintain a specific air pressure value. a, b, c, and d refer to the amount of pressure required by the user to lift the selected weight, among which d is the largest and a is the smallest. If the user selects a larger weight, these 4 pressure levels will increase accordingly. For example, if the dumbbell weight "10 kg" is selected in this game, the corresponding pressure during the lifting process is a=5mmHg, b=10mmHg, c=15mmHg, d=20mmHg. Assume the m value is 500 microseconds.

When the user starts to generate pressure with the mouthpiece, the P value will increase (P>0) and the game will start with the first frame of the animation updated. As the pressure generated by the user with the mouthpiece increases, when the pressure exceeds 5mmHg, the game animation is updated to the second frame, and the dumbbell will be lifted higher and higher. The same continues until the last frame, and each frame will be updated with a 500 microsecond delay so that the animation looks smooth. When the pressure exceeds 20mmHg, the user must maintain the maximum pressure level. After a delay of m seconds, the animation will be updated to the last frame to show the user's victory in the game. If the user fails to stay at that level or below the P-value, the user's game will be shown as failed.

It should be noted that the embodiment of the present invention uses the display screen and air pressure sensor of the mobile phone as the user interface to realize human-computer interaction in the respiratory rehabilitation training system, adding versatility, fun and attraction to boring respiratory rehabilitation exercises. During the rehabilitation exercise process, the software system (App on the mobile phone) receives the data generated by the patient and displays the data in various forms such as animation, music, and generated respiratory test results. The software system can be installed on a smartphone or tablet.

It can be understood that the present invention uses a non-invasive respiratory muscle strength test that can measure the strength of respiratory muscles (MEP and MIP). Figure 5 shows the test module of the software measuring the maximum expiratory pressure. (MEP or PEmax) page. This page displays a graph on the display using the patient's MEP values and respiratory muscle pressure data over time. At the same time, it also displays the reference normal range for comparison based on age and gender, and comments on the results, improving the user experience. Furthermore, the present invention also records and maintains the patient's respiratory rehabilitation training records/data, and uses this as a long-term respiratory system health record of the patient. Another important function of the system is to perform statistical analysis based on the collected data to detect and demonstrate improvements in the patient's performance during rehabilitation exercises. In different training modes, users can view training records in different time periods by calling the training data stored in the data storage module.
