The invention is described in further detail below with reference to the following detailed description and accompanying drawings:

as shown in fig. 1-20, an embodiment of the present invention provides a respiratory pattern monitoring apparatus including a support assembly and a control assembly.

The supporting component is used for being worn on the face of a human body. The support assembly is provided with a face recess 3 for receiving at least part of a human face, and a vent 14 communicating with the face recess 3. The face slot 3 is able to accommodate a respiratory filtration resistance 5.

The control assembly comprises a control member configured on the support assembly, a first detection member 10 and a communication device. The first detecting member 10 is disposed at the ventilation hole 14 for detecting the breathing condition of the human body.

In this embodiment, the first detecting member 10 may be a temperature sensor and/or a humidity sensor and/or a carbon dioxide measuring sensor; (particularly, flexible electronic sensors) in which the breathing rate and the breathing temperature are different because the person is in different states. Taking a temperature sensor as an example, on one hand, since the tidal volumes of exhaled air and inhaled air of a person under different breathing conditions (such as moving, standing, sitting still, lying down, etc.) are different, under a given (cotton filter) air resistance condition, the tidal volume sensor directly correlates with the concentration of the tidal/carbon dioxide in the cavity, and therefore the resistance/capacitance values of the sensor are different, so as to detect the breathing pattern of the person (as shown in fig. 13).

Specifically, the graph obtained by the continuous change of the tidal volume caused by free breathing of people along with time has the following significance: (1) The respiratory function data obtained by the conventional respiratory function monitor can be obtained. (2) Continuous and quantitative characterization is carried out on symptoms such as cough, dyspnea, apnea and the like, and direct correlation between the symptoms and the functional change of a correlator and respiratory and pulmonary diseases is carried out through spectrum analysis; (3) Meanwhile, the system can be used as the monitoring and tracking index of patients with respiratory and pulmonary diseases.

As shown in fig. 13 and 14, the breathing pattern reflects the frequency and amplitude characteristics of the breathing wave as a function of time of the frequency and amplitude of the breathing. If breathing is uniform, it should be regular, or, in this case, a regular wave with a certain frequency and a given amplitude is obtained. If the physical state or the motion state changes, the frequency and the amplitude of the respiratory wave can be generated; if the respiratory tract or the lung is changed or diseased, the frequency and the amplitude of the respiratory wave can be correspondingly changed, including the frequency modulation and the amplitude modulation of the respiratory wave or the simultaneous occurrence of the frequency modulation and the amplitude modulation;

as shown in fig. 15, in principle, these changes can be displayed in the spectrum space by wavelet spectrum analysis. In other words, respiratory tract or lung changes or lesions occur, and characteristic changes can be found in the spectrum space; through artificial intelligence big data, the characteristics of diseases of respiratory tract or lung caused by pathological changes can be found in a frequency spectrum space, and artificial intelligence auxiliary diagnosis and tracking of the diseases are realized.

As shown in fig. 16 to 19, are a respiratory map and a wavelet spectrum analysis map of different motion states. Wherein, the respiration (amplitude) of the person who does not snore is stable. The breathing (amplitude) of a person lying down has a periodic fluctuation (indicating that breathing is obstructed).

FIG. 20 shows a respiratory map and wavelet spectral analysis of a lung cancer patient. Wherein the respiratory spectrum is severely split; the dominant frequency splits up several specific spectra.

On the other hand, the frequency spectrum of the obtained respiratory map is different from the body temperature spectrum when people are in different respiratory states, for example, the temperature of the air flow exhaled during cold is higher, the flow of the air flow exhaled during deep breathing is higher, and the frequency is lower. Different respiratory diseases or lung diseases cause respiratory organ variation, which results in spectral change of respiratory spectrum under the same condition. Also sneezing, coughing, dyspnea, apnea, etc., all respond to changes in the respiratory spectrum. Based on the principle, the control component can generate a respiration map according to a resistance/capacitance change deformation curve measured by the tidal/carbon dioxide sensor to reflect the respiration state of the person, and different respiration states can represent the physiological state or health state of the person to a certain extent, so that the monitoring of the physiological state of the person can be realized, for example, whether the person is a cold, a fever or shortness of breath, and the like, as shown in fig. 9 and 10, and as shown in fig. 14 to 20.

It should be noted that in other embodiments of the invention, there are three main key components, (1) a mask that is ergonomically better airtight; (2) A cotton filter/resistance net with fixed and adjustable air resistance and an installation window; (3) The first detecting member 10 can be a flexible electronic sensor such as a humidity sensor or a carbon dioxide measuring sensor, and the simultaneous existence of the three key parts can quantitatively and real-timely monitor the respiratory condition and health condition of the human body by measuring the continuous change of the humidity content or the carbon dioxide content in the exhaled air of the human body, and the solutions are all within the protection scope of the present invention.

In this embodiment, the control member is electrically connected to the first detecting member 10 and the communication device, and is configured to transmit the breathing condition of the human body detected by the first detecting member 10 through the communication device.

In particular, the communication device may be connected to an external monitoring terminal, such as a mobile phone of a user or a monitoring platform of a hospital, so that the breathing condition of the human body detected by the first detecting member 10 may be transmitted to the monitoring terminal through the communication device, and the monitoring terminal generates a breathing pattern. The data transmission module may be a WiFi module, a bluetooth module, an NFC module, or a 2/3/4/5G GSM module, etc., which is not limited in the present invention.

In addition, the respiratory pattern can be displayed locally, and particularly, the respiratory pattern monitoring device further comprises a display part 2, and the display part 2 is fixed on the supporting component. The control part detects the breathing state of the human body (such as normal breathing, increased breathing volume, dyspnea, cough, apnea, respiratory obstruction, snore and the like) through the first detection part 10, and directly displays the breathing pattern of the human body through a proper platform (such as the display part 2). Because continuous and wireless breathing pattern measurement and direct result display are carried out, the state of a human body is monitored, and medical staff can observe a user conveniently.

In this embodiment, the breathing filter resistance 5 is disposed at the vent hole 14, and may be specifically a breathing filter cotton, and the breathing filter cotton has two functions, one of which is that when the mask is sealed, external air can be blocked from passing through the vent hole 14 through the inside of the apparatus, and air passing resistance of breathing gas and gas instantaneous pressure are maintained, so that the detection accuracy and the reactivity of the first detection element 10 are affected; secondly, the transmission speed and the cooling speed of the gas exhaled by the human body can be reduced, so that the temperature and humidity conditions of the gas exhaled by the human body can be more accurately detected by the first detection piece 10; and thirdly, the filter has the function of filtering the dust and biological pathogenic particles such as bacteria and viruses.

In summary, the present embodiment is implemented by providing a respiratory mask (i.e., support assembly 3) (1) with a cotton filter/resistive web (i.e., respiratory filtration resistance 5); (3) The first detection part 10 detects the breathing state of the human body, and the control part obtains the breathing pattern of the human body according to the breathing state, so that the breathing state, the physiological state and the like of the user can be monitored according to the breathing pattern, and the health state of the human body is monitored dynamically in real time. The invention has at least the following advantages:

As shown in fig. 5 to 7, in an alternative embodiment of the present invention based on the above embodiment, the support assembly comprises a support 7, a housing 13 and two ear-hooks (not shown). The bracket 7 is provided with a face slot 3. The housing 13 is provided with a vent 14.

The display 2 is disposed on the surface of the housing 13. The two ear hooks are made of elastic materials and are respectively arranged on two sides of the bracket 7 or the shell 13.

Specifically, the shell 13 is arranged on the support 7, so that the breathing pattern monitoring equipment is more attractive in appearance and has certain aesthetic feeling. Also, mounting the control member in the component cavity 4 between the housing 13 and the support 7 enables the assembly of the breath-pattern monitoring apparatus to be simpler.

In other embodiments, as an equivalent technical solution of the present invention, the control member, the first detecting member 10, may be directly mounted on the wall of the face slot 3 without using the housing 13, and the same effect can be achieved. The present invention is not limited to a specific mounting structure of the control member and the first detecting member 10.

As shown in fig. 5 to 7, in an alternative embodiment of the present invention based on the above embodiments, the bracket 7 is provided with a vent hole 21 facing the vent hole 14, and a first control groove 20 and a second control groove 22 located on both sides of the vent hole 21. The air passing hole 21 is used for communicating the air vent hole 14 and the face groove 3. The first and

second control grooves

20 and 22 extend from a side of the bracket 7 away from the face groove 3 to a side of the face groove 3 to form a protrusion in the face groove 3.

Specifically, the bracket 7 is roughly in a cambered surface structure, and a face groove 3 is formed in an inward groove at one side; the other side is convex outwards to form a surface. The middle upper position of the bracket 7 is in a hollow state and is only provided with a plurality of arc-shaped rod-shaped geometric bodies.

Referring to fig. 6 to 7, in an alternative embodiment of the present invention, the first detecting member 10 is disposed at a position (not shown) opposite to the nostril of the human body on the supporting component. Preferably, it extends from the support 7 into the face slot 3 in the form of an extension cord, forming a free end that can move freely. When in use, the free end part is adhered and fixed on the respiratory filtration resistance piece 5 so as to be closer to the position of the nostril.

In an alternative embodiment of the invention, based on the above embodiment, the support assembly further comprises a resilient member (not shown) traversing the face slot 3. The first detecting member 10 is disposed on the elastic member such that the first detecting member 10 is positioned between the nose and the mouth of the human face when the human face is fitted into the face slot 3. Through the setting of elastic component for the position that is close to the nostril that first measuring piece 10 can be more, thereby the breathing condition of human body of more accurate detection has fine practical meaning.

The second detecting element 16 is disposed at a position where the bonding portion 1 is bonded to the cheek. The second detecting member 16 is a temperature sensor for detecting the body temperature of the human body. The control assembly is electrically connected to the second detection member 16. The respiratory map monitoring apparatus is capable of simultaneously monitoring the respiratory condition and the body temperature condition of a user via the first detecting member 10 and the second detecting member 16.

On the basis of the above embodiments, in an optional embodiment of the present invention, the health monitoring of the human body may also be realized by performing wavelet transform on the respiratory atlas.

In particular, the fourier transform is a linear global orthogonal transform, cannot identify the time and frequency of occurrence of a specific event, and cannot be applied to nonlinear-non-stationary signal analysis in principle. The respiratory signals constituting the respiratory map are typical nonlinear-nonstationary signals, and are very suitable for being analyzed by wavelet transform (wavelet transform) to obtain energy-frequency-time distribution in the signals, and the scale/frequency and the intensity/energy corresponding to different events are described in a time-frequency space. For a signal s (t), its continuous wavelet transform is defined as

Where ψ is a selected wavelet, W _s And (a, t) are corresponding wavelet coefficients, and a is a corresponding scale. For any scale and time of day, a corresponding instantaneous frequency may be defined,

the wavelet transform thus reformulates a given signal in the energy-scale/frequency-time space. The method is limited by the inaccuracy principle, and the time-scale/frequency corresponding to a certain event cannot be accurately positioned due to the fact that the resolution is not high. In order to improve the resolution of wavelet transform, a synchronous squeeze wavelet transform method has been proposed in recent years, i.e. the energy is more concentrated on the corresponding center frequency by a squeeze operation

Wherein A (t) = { a: W _s (a,t)≠0}，T _s And (omega, t) is the distribution of the wavelet coefficients obtained after extrusion along with time-frequency. The synchronous squeeze wavelet can partially inhibit the problem of energy leakage caused by harmonic waves, and thus is widely applied. The present embodiment uses a simultaneous squeeze wavelet to analyze the respiration signal.

The upper half of fig. 11 shows 300 seconds of respiratory data acquired during normal breathing, and the lower half of fig. 11 shows the corresponding synchronous squeeze wavelet energy-time-frequency distribution diagram, wherein the horizontal dotted line is 0.31Hz respiratory dominant frequency obtained by fourier spectrum identification. It can be seen that although the corresponding energy varies with time, the breathing frequency is substantially constant.

The upper half of fig. 12 shows 320 seconds of respiratory data acquired during sleep, wherein apnea occurs at 190-225 seconds, and the lower half of fig. 12 shows a corresponding synchronous squeeze wavelet energy-time-frequency distribution diagram wherein the horizontal dashed line is 0.31Hz respiratory frequency identified by fourier energy spectrum. From this data there can also be harmonic phenomena, i.e. there is also energy distributed at 0.62 Hz. When an apnea occurs, energy is concentrated in the lower frequencies. Therefore, the synchronous extrusion wavelet can effectively identify the occurrence time and the occurrence frequency of different events, and is used for construction, feature identification and diagnosis of a respiratory map.

The second embodiment of the present invention further provides a respiratory map monitoring system, which includes a monitoring terminal and the respiratory map monitoring apparatus as described above, where the monitoring terminal is in communication connection with the respiratory map monitoring apparatus through the communication module, and can generate a respiratory map by receiving the respiratory condition sent by the communication module.

The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention, and various modifications and changes may be made by those skilled in the art. Any modification, equivalent replacement, or improvement made within the spirit and principle of the present invention should be included in the protection scope of the present invention.
