[0002] For patients with impaired breathing and lung function, breathing training is helpful for the rehabilitation of their cardiopulmonary function. There are many methods for breathing function rehabilitation training, but most of them are through adjusting the breathing mode and exercise mode step by step, and repeatedly exercising to improve the lung capacity and strengthen the respiratory muscle strength to achieve the purpose of rehabilitation of breathing function.

Based on the embodiments in the present application, all other embodiments obtained by a person of ordinary skill in the art without creative work fall within the protection scope of the present application.

[0047] As shown in FIG. 1, Figures 1 to 6 The first embodiment of the present application provides a digital mask for realizing respiratory training, aiming to improve at least one of the above technical problems.

[0048] To solve the above technical problems, the present application provides a digital mask for realizing respiratory training, which comprises a mask support 3 to be worn on the face of a human body, and a mask shell 1 and a breathing valve assembly and a real-time respiratory monitoring and control assembly arranged on the mask support 3. The mask support 3 is provided with a first air passage hole 6 and a second air passage hole 7. The mask shell is provided with a first through hole 4 opposite to the first air passage hole 6, and a second through hole 5 opposite to the second air passage hole 7. The first air passage hole 6 and the first through hole 4 can be communicated through a mask filter cotton 2. The breathing valve assembly is arranged in the second air passage hole 7, and is used to communicate the second air passage hole 7 and the second through hole 5. The breathing valve assembly is configured as a one-way valve, which is opened when the user exhales and closed when the user inhales. The real-time respiratory monitoring and control assembly comprises a breathing sensor 10 arranged on the mask support, a power module 11, and a signal processing and communication module 12; the power module 11 is electrically connected with the breathing sensor 10 and the signal processing and communication module 12. The breathing sensor 10 is arranged inside the second air passage hole 7, and is used to detect the respiratory parameters of the human body; the signal processing and communication module 12 can send the respiratory parameters of the human body detected by the breathing sensor 10, for example, to a remote monitoring terminal through a cloud platform.

[0049] As shown in FIG. 2, Figure 2 , Figure 3 , Figure 5 and Figure 6As shown, based on the above embodiment, in an optional embodiment of the present invention, the breathing valve assembly includes a valve core seat 8 configured on the second air hole 7, and a valve chip 9 configured on the side of the valve core seat 8 away from the user's face. The valve chip 9 is constructed to cover the second air hole 7. The valve chip 9 is used to adhere to and seal the second air hole 7 during inhalation, and to detach from and open the second air hole 7 during exhalation. Preferably, the valve chip 9 is made of silicone. In other embodiments, the valve chip 9 can be made of other existing materials such as nanofiber membranes, and the present invention does not specifically limit this.

[0050] like Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, in this embodiment, the valve core seat 8 is provided with a snap protrusion, and the valve chip 9 is provided with a snap groove. The valve chip 9 can be directly fixed on the snap protrusion through the snap groove, thereby being fixed on the valve core seat 8. Preferably, in other embodiments, a limiting column is provided on the valve core seat 8, and the valve chip 9 is directly placed on the limiting column. The breathing valve assembly also includes a valve core cover configured on the valve core seat 8. The valve core cover is configured on the valve core seat 8, covering the end of the limiting column, thereby preventing the valve chip 9 from detaching from the valve core seat 8.

[0051] like Figure 2 、 Figure 3 、 Figure 5 and Figure 6 As shown, in this embodiment, the valve core seat 8 and the mask bracket 3 are an integrated structure. Preferably, in other embodiments, the breathing valve assembly can be an independently provided valve core seat 8, which is fixed to the mask bracket 3 by ultrasonic welding, glue connection, etc. The present invention does not limit the specific fixing method of the breathing valve assembly.

[0052] like Figure 1 、 Figure 3 、 Figure 5 and Figure 6 As shown, in this embodiment, the first air holes 6 are located on the mask frame 3 directly opposite the nose bridge and on both sides of the nose bridge. The second air holes 7 are located on the mask frame 3 directly opposite the mouth. Specifically, the second air holes 7 are located at the mouth position. When exhaling from the nose or mouth, the person can blow directly toward the second air holes 7, accelerating the flow of exhaled air out of the mask.

[0053] like Figures 2 to 6 As shown, in this embodiment, the digital respiratory training mask also includes a mask filter 2. At least a portion of the mask filter 2 is fan-shaped, covering the first air hole 6. Specifically, the first air hole 6 is located directly opposite the nose bridge and on both sides of the nose bridge on the mask support 3. Therefore, the roughly fan-shaped mask filter 2 can be bent to form an arched structure that precisely covers the first air hole 6.

[0054] Preferably, the mask filter cotton 2 is Y-shaped, the upper part is bent to form a structure with a certain arc shape, and the lower part is provided with a through hole for connecting the second air hole 7 and the second through hole 5.

[0055] like Figures 3 to 6 As shown, in this embodiment, the mask filter 2 is disposed between the mask housing 1 and the mask bracket 3. Specifically, the mask housing 1 is detachably mounted on the mask bracket 3. The mask filter 2 is detachably mounted on the mask housing 1. Placing the mask filter 2 between the mask bracket 3 and the mask housing 1 effectively prevents the mask filter 2 from falling off during use.

[0056] The mask filter 2 includes a non-woven fabric layer and a meltblown fabric layer; the number of non-woven fabric layers is 1 or 2; the number of meltblown fabric layers is 1, 2, 3, or 4. Specifically, as shown in the table below, by varying the number of non-woven fabric layers and meltblown fabric layers, the filtration efficiency and breathing resistance can be adjusted, adapting to the protection requirements of different locations, while also enabling auxiliary respiratory function training and auxiliary treatment of certain respiratory and lung diseases.

[0058]

[0059] In this embodiment, the respiratory sensor 10 may be a carbon dioxide sensor or a temperature and humidity sensor, etc., which is not specifically limited in the present invention.

[0060] The power module 11 may be a lithium battery.

[0061] The signal processing and communication module 12 may be an MCU integrated with a communication module, and the communication module may be a 2 / 3 / 4 / 5G module or a Bluetooth module, which is not specifically limited in the present invention.

[0062] Among them, through the real-time respiratory monitoring component, this embodiment can also realize a series of functions such as real-time synchronous monitoring of breathing, respiratory training, and lung function testing.

[0063] Specifically, if Figure 7 As shown, the user's breathing conditions (including breathing frequency, breathing intensity, etc.) can be sent to the remote monitoring terminal 200 through the signal processing and communication module 12. The monitoring terminal 200 receives the breathing conditions sent by the signal processing and communication module 12 to generate a breathing spectrum and breathing parameters of the subject, and determines the training parameters based on the breathing parameters to monitor the breathing conditions and the effect of breathing training in real time.

[0064] The monitoring terminal 200 can be a user's mobile phone, a user's relative's mobile phone, a medical staff's mobile phone, and the like, and the present application is not limited in particular.

[0065] To sum up, the embodiment of the present application can achieve the following technical effects:

[0066] 1. By connecting the breathing valve assembly with filter cotton of different thicknesses and materials, the breathing resistance can be changed, and the auxiliary training of breathing function and the auxiliary treatment of some respiratory and lung diseases can be realized.

[0067] 2. By collecting and monitoring the user's breathing parameters in real time, a breathing map is formed, and the user's breathing condition and rehabilitation condition can be automatically and accurately judged through the breathing map, the accuracy and timeliness of the judgment are improved, and the possibility of misjudgment caused by manual judgment is avoided.

[0068] Please refer to Figure 7 The second embodiment of the present application provides a training system, which comprises the breathing training digital mask, the cloud platform 300 and the monitoring terminal 200 as described above; wherein:

[0069] The breathing training digital mask is used for acquiring the breathing parameters of the user under different mask filter cotton materials and thicknesses, and sending the breathing condition to the cloud platform.

[0070] The cloud platform is used for sending the breathing condition to the monitoring terminal.

[0071] The monitoring terminal is used for generating a breathing map according to the breathing condition, and judging the breathing limit of different users according to the breathing map, adjusting the filter cotton resistance and the training duration according to the physical fitness and health status of different individuals, so as to obtain the best breathing parameters.

[0072] The monitoring terminal is also used for comprehensively evaluating the training and rehabilitation effects of the breathing training according to the long-term tracking of the breathing parameters and the breathing map.

[0073] Specifically, when the user is subjected to the breathing training, the lung function and the normality of the user's breathing need to be observed. Here, the normality of the breathing needs to pay attention to the following points:

[0074] 1. Whether the breathing frequency is too slow;

[0075] 2. Whether the breathing frequency is too fast, that is, whether the breathing is too rapid;

[0076] 3. Whether the user's breathing limit is reached.

[0077] During the breathing training, if these situations occur, timely adjustment and alarm are needed to avoid causing harm to the user's health during the training.

[0078] As shown in Figure 8 Normally, people breathe through the nose, but if the respiratory function of the lungs has some problems or exceeds the limit of lung function, the nose and mouth will breathe at the same time, which can be identified by the breathing spectrum as shown in Figure 8 If this situation occurs, it means that the current breathing has reached the limit of lung function, and the resistance of breathing should be appropriately reduced, such as reducing the number or thickness of the filter cotton, etc.

[0079] As shown in FIGS. 9(a)-(b), if the breathing is too slow, for example, less than ten times per minute, it may cause difficulty in breathing, and an alarm and adjustment of the breathing resistance are needed.

[0080] As shown in FIGS. 10(a)-(b), if the user has rapid breathing (frequency greater than 20 times per minute), this situation is mostly caused by insufficient oxygen. If this situation occurs, an alarm is needed to stop the breathing training or reduce the breathing resistance.

[0081] As shown in Figure 11 , Figure 11 The improvement effect of the lung function of the user after the breathing training can be seen. The black line shown is the breathing spectrum of the patient with respiratory slow lung, and the red line is the breathing spectrum of the healthy person. By monitoring the breathing of the patient in real time and observing whether the changes of the breathing spectrum and the breathing parameters gradually approach the breathing spectrum and the breathing parameters of the healthy person, it can be judged whether the breathing condition of the patient is improved, so as to comprehensively evaluate the breathing training and rehabilitation effect.

[0082] In summary, in the embodiment, the breathing condition of the user can be understood in real time according to the generated breathing spectrum, and the breathing training digital mask is adjusted in time according to the breathing condition of the user to reach the training limit of the user, so as to avoid the damage to the health of the user caused by the high-intensity breathing training or the low-intensity breathing training that cannot achieve the expected training effect.

[0083] In addition, the recovery of the lung function of the user can be directly understood by comparing the breathing spectrum with the breathing spectrum of the healthy person, so as to know the training effect and the rehabilitation effect in the current stage in real time.

[0084] The above is only a preferred embodiment of the present application and is not used to limit the present application. For those skilled in the art, the present application can have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principles of the present application shall be included in the protection scope of the present application.
