Detailed Description
The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application.
It should be noted that if directional indications (such as upper, lower, left, right, front and rear \8230;) are referred to in the embodiments of the present application, the directional indications are only used for explaining the relative positional relationship between the components in a specific posture (as shown in the attached drawings), the motion situation, etc., and if the specific posture is changed, the directional indications are correspondingly changed.
It should be noted that if descriptions related to "first", "second", etc. exist in the embodiments of the present application, the descriptions of "first", "second", etc. are only used for descriptive purposes, and are not to be construed as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of the feature.
The first embodiment of the application provides a physiological sound acquisition device, which comprises a bone conduction sensor and a first microphone; the bone conduction sensor is used for collecting a physiological sound signal, the first microphone is used for collecting a first environment noise signal, and the first environment noise signal is used for correcting the physiological sound signal.
The physiological sound signals include heart sound signals, lung sound signals and the like. Among them, heart sound (heart sound) refers to sound generated by mechanical wave phenomenon caused by contraction of cardiac muscle, closure of heart valves, and impact of blood against ventricular wall, aortic wall, etc.; the main source of lung sounds is the formation of vacuoles and ruptures of air through the action of secretions in the respiratory tract and airways, such as fluid accumulation, sputum, blood, and the like. The heart sound signal is a signal obtained by collecting heart sound, and the lung sound signal is a signal obtained by collecting lung sound.
In the following description, the bone conduction sensor collects a heart vibration signal, the collected vibration signal needs to be subjected to noise signal elimination and useful signal amplification by a filtering unit and a signal amplification unit, and the first environmental noise signal also needs to be subjected to noise signal elimination and useful signal amplification. When bone conduction transducer gathered the heart sound signal, needed the user to press close the earphone to the chest wall to make the heart sound signal that bone conduction transducer gathered more accurate.
Referring to fig. 1, fig. 1 is a schematic diagram of a heart sound signal (top) and a first environmental noise signal (bottom) acquired by a physiological sound acquisition device according to the present application. In order to avoid the acquisition error (including noise caused by the movement of the fingers of the user, noise caused by the friction between the earphone and the clothes, etc.) caused by the physiological sound signal acquisition method, the first environmental noise signal acquired by the first microphone needs to correct the heart sound signal. The specific process is as follows: extracting key heart sound signal characteristics (determined by normal heart sound signals when the heart is free of pathological changes in medicine) as mark points, and aligning the heart sound signals with the first environmental noise signals; the heart sound signal is used as a main signal, the first environmental noise signal is used as a correction signal, and whether an abnormal signal (abnormal sound characteristic) in the main signal is caused by the abnormal heart of the user or a collection error is judged. The normal heart sound signal is used for marking a normal signal (marking a peak and/or a trough) in the heart sound signal, and the abnormal signal in the heart sound signal is a signal except the normal signal and has an obvious peak and/or trough. It should be noted that, when an abnormal signal exists in the heart sound signal and the abnormal signal also exists in the first environmental noise signal, the abnormal signal is determined as the acquisition error; when an abnormal signal exists in the heart sound signal but the abnormal signal does not exist in the first environmental noise signal, the abnormal signal is determined to be caused by the heart abnormality of the user.
Illustratively, the apparatus further comprises a second microphone for acquiring a second ambient noise signal; removing the ambient noise feature in the physiological sound signal only when the same ambient noise feature is present in the second ambient noise signal as in the first ambient noise signal.
For the second ambient noise signal, the processing for removing the noise signal and amplifying the useful signal is also required. It should be noted that the second microphone needs to be located far away from the bone conduction sensor, for example, both are located at opposite sides in the earphone, so that when the bone conduction sensor is close to the chest wall, the second microphone is far away from the chest wall, so that the second microphone can receive clear ambient noise. The environmental noise is the voice of the person speaking loudly in the environment, the door closing voice and the like. Note that the noise reduction processing is a process of subtracting the second ambient noise signal from the heart sound signal.
It should be noted that, before the heart sound signal is subjected to the noise reduction processing by the second environmental noise signal, the second environmental noise signal and the heart sound signal also need to be aligned.
The second microphone is arranged for the purpose of: and carrying out secondary judgment on abnormal signals in the heart sound signals, thereby improving the accuracy of removing the environmental noise characteristics in the heart sound signals.
Exemplarily, the device further comprises a reminding module, wherein the reminding module is used for outputting first reminding information to remind a user to adjust the measurement posture when the intensity of the physiological sound signal is less than or equal to a preset physiological sound signal intensity threshold value; and when the noise signal intensity of the second environment noise signal is greater than or equal to the preset noise signal intensity threshold value, the reminding module is further used for outputting second reminding information to remind a user to select a new environment to collect physiological sound.
The reminding module comprises a signal output module such as a loudspeaker, a display and the like and is used for outputting sound signals, character signals or image signals and the like.
The reason why the physiological sound signal intensity of the physiological sound signal is less than or equal to the preset physiological sound signal intensity threshold value is that the physiological sound collecting device is not close to the human body. For example, the user may use the device through clothes or may not closely attach the device to the chest. At the moment, the measurement posture of the user is incorrect, and the user is reminded by outputting first reminding information so that the physiological sound acquisition device is close to the human body. For example, the first reminding message is "unsuccessfully collect physiological sound, please try again after the device is attached to the chest". When the intensity of the physiological sound signal is greater than the preset intensity threshold of the physiological sound signal, the reminding information does not need to be output. The preset physiological sound signal intensity threshold may be set as needed, and this embodiment is not limited specifically.
The noise signal intensity of the second ambient noise signal is greater than or equal to the preset noise signal intensity threshold, and the measured heart sound signal is seriously influenced by noise at the moment, so that the acquired physiological sound signal is inaccurate. Therefore, the user can be reminded to select a new environment to collect physiological sound by outputting the second reminding information, and the second reminding information does not need to be output when the noise signal intensity of the second environment noise signal is smaller than the preset noise signal intensity threshold value. For example, the second reminder message is "please perform physiological sound collection in quiet environment". The preset noise signal strength threshold may be set as needed, and this embodiment is not particularly limited.
Compared with the prior art that auscultation is carried out when a doctor visits a doctor, and the auscultation needs to be carried out by a doctor in a hospital, so that the acquisition of the physiological sound is inconvenient, the physiological sound acquisition device comprises a bone conduction sensor and a first microphone; the bone conduction sensor is used for collecting a physiological sound signal, the first microphone is used for collecting a first environment noise signal, and the first environment noise signal is used for correcting the physiological sound signal. This application gathers physiological sound signal through the bone conduction sensor among the physiological sound collection device to come the operation by the device user and can realize acquireing of physiological sound, and need not to be operated by the doctor and acquire physiological sound. In addition, after the physiological sound signal is corrected through the first environmental noise signal collected by the first microphone, the accuracy of the physiological sound signal is improved.
For example, the physiological sound collecting device may be used in an earphone, a watch, or the like, or may be an independent device having only a physiological sound collecting function, and the embodiment of the specific implementation of the physiological sound collecting device is not specifically limited in this embodiment.
In this embodiment, a physiological sound collecting device is taken as an example in an earphone, referring to fig. 2, fig. 2 is a schematic structural diagram of an earphone according to an embodiment of the physiological sound collecting device of the present application.

Optionally, the wearable device is used as a watch (including the physiological sound collecting device and the watch body) in the embodiment, the physiological sound collecting device is separately arranged and is wirelessly connected with the watch body, and the physiological sound collecting device is an earphone. Referring to fig. 3 and 4, fig. 3 and 4 are schematic structural views of a watch according to an embodiment of the wearable device of the present application. Wherein, earphone accessible embedding, magnetism inhale mode such as place on the wrist-watch.

the first communication module comprises a Bluetooth module or an Ultra Wide Band (UWB) module;

It should be noted that, the process of processing the heart sound signal in the first embodiment may also be implemented in the watch body, that is, the earphone sends the heart sound signal, the first environmental noise signal and the second environmental noise signal collected by the earphone to the watch body, and the watch body corrects and reduces the noise of the heart sound signal through the first environmental noise signal and the second environmental noise signal, respectively. The correction and noise reduction processing is basically the same as the implementation manner in the first embodiment, and is not described herein again.
It can be understood that when the physiological sound collecting device and the wearable device body are integrally arranged, the user can use the wearable device to press close to the chest wall.
Illustratively, the wearing subject further comprises a cardiac monitoring trigger data acquisition module; the heart monitoring trigger data acquisition module is used for acquiring heart monitoring trigger data; the heart monitoring trigger data is used for judging whether the user belongs to a heart health key attention object, and if yes, the wearing main body enters a heart monitoring mode.

Wherein the body fat detection module comprises a BIA (Bio-impedance analysis, bio-resistance measurement) sensor.
It can be understood that when the body fat percentage of the user exceeds the standard, that is, the body fat percentage is greater than or equal to the preset body fat percentage threshold, the heart of the user is most likely to be in an unhealthy state, and for such users, the heart health key attention object can be determined; if the body fat rate is less than the preset body fat rate threshold value, the user can be determined that the unhealthy state of the heart of the user is small, and the heart monitoring mode is not entered. The preset body fat percentage threshold may be set as needed, and this embodiment is not particularly limited.
Illustratively, the cardiac monitoring trigger data acquisition module is a motion detection module, and the cardiac monitoring trigger data is motion data; the exercise data is used for judging whether the frequency of the user participating in exercise is smaller than or equal to a preset frequency threshold value, if yes, the user is determined to belong to a heart health key attention object, and the wearing main body enters a heart monitoring mode.

Specifically, the heart monitoring trigger data acquisition module comprises a body fat detection module and a motion detection module, and the heart monitoring trigger data comprises body fat rate and motion data; if the body fat rate is greater than or equal to a preset body fat rate threshold value and the frequency of the user participating in the exercise is less than or equal to a preset frequency threshold value, determining that the user belongs to a heart health key attention object, and enabling the wearing body to enter a heart monitoring mode.
