Description

Technical Field

[0001] The invention relates to medical equipment, in particular to a device for suppressing depression. Background Art

[0002] Depression, also known as depressive disorder, is a major type of mood disorder with significant and persistent low mood as the main clinical feature. Clinically, it can be seen that the low mood is disproportionate to the situation. The depression of emotions can range from melancholy to grief, inferiority and depression, and even pessimism and world-weariness. There may be suicidal attempts or behaviors, and even stupor. Some cases have obvious anxiety and motor agitation. In severe cases, psychotic symptoms such as hallucinations and delusions may occur. Each attack lasts for at least 2 weeks, and even several years for the elderly. Most cases tend to relapse. Most attacks can be relieved, and some may have residual symptoms or become chronic.

[0003] Common causes of depression include: genetics, HPA axis, cytokines, sex hormones, neurotrophic factors, etc. Common symptoms include: low mood, slow thinking, decreased volitional activity, and cognitive impairment.

[0004] Depression is a physiological emotion of a person, and depression can be treated by the following means: Drug therapy, which is the main treatment measure for moderate and above depressive episodes. Psychotherapy, for patients with depressive episodes with obvious psychosocial factors, psychotherapy is often required in combination with drug therapy. Physical therapy, a new physical therapy method has emerged in recent years - repetitive transcranial magnetic stimulation (rTMS) therapy, which is mainly suitable for mild to moderate depressive episodes. It has certain side effects and even dependence, which puts a burden and impact on the body. The above three treatment methods have the following problems: 1. It has certain side effects and even dependence, which puts a burden and impact on the body; 2. It is not convenient and needs to be treated in a specific place. 3. The treatment price is relatively expensive. Summary of the invention

[0027] Figure 1 A diagram of the structure of a device for suppressing depression. DETAILED DESCRIPTION

[0028] In order to make the purpose, technical solution and advantages of the embodiments of the present invention more clear, the technical solution in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention.

[0029] See also Figure 1 , the device for suppressing depression provided in the embodiment of the present invention includes an audio playback unit, a control panel, a device display, a data storage device, a Bluetooth component and a power supply. The device binds the depressed user with the mobile phone APP program through the Bluetooth component and matches the most suitable audio for the depressed user; the audio playback unit plays the first audio signal set to the depressed user. Specifically, the audio player can be a bone conduction headset or an ordinary dynamic headset. The first audio signal set includes multiple first audio signals, wherein the first audio signal is a test signal. People with depression symptoms can use soothing folk music and light music to help balance emotions, keep the mind relaxed and quiet, thereby improving depression. Therefore, the test signal can select some audio clips such as folk instruments, environmental sounds of mountains and rivers, and insects and birds, and multiple audio clips form a first audio signal set.

[0030] The brain wave signal acquisition unit collects the brain wave signals of the depressed user when the audio player plays the first audio signal set to the depressed user. Depression is often accompanied by abnormal sleep cycles and structures. During nighttime sleep, the EEG shows a decrease in NREM III and IV stages, a shortened REM sleep latency, that is, a decrease in total sleep time, a prolonged sleep latency, an increase in awakenings and early awakenings, and a decrease in deep sleep. The EEG of patients with pseudodementia is mostly normal, while most patients with organic dementia with or without secondary depression have clear EEG abnormalities, and most of them are moderate to severe abnormalities. Therefore, collecting brain wave signals can accurately reflect the current state of depressed users.

[0031] The brain wave analysis unit analyzes the brain wave signal of the depressed user to obtain a brain wave analysis result. When the depressed user has an attack, the brain wave will show obvious changes, for example, the theta wave in the brain wave will show a dominant diffuse theta wave activity and a oscillatory theta wave activity. Therefore, the theta wave can be analyzed to determine the user's state.

[0032] An audio selection unit, the audio selection unit is used to select a second audio signal set from the first audio signal set according to the brain wave analysis result. Since not all test clips have an inhibitory effect on the user's depression, we need to select truly effective first audio signals from the first audio signal set to form the second audio signal set. If the played audio signal is effective for users with depression, then when the audio signal is played, the θ wave will be in a reasonable and normal range. Therefore, through the analysis results of the θ wave, we can accurately select the second audio signal set from the first audio signal set.

[0033] The audio splicing unit splices the second audio signal set into a third audio signal, and the audio playback unit plays the third audio signal to the depressed user. Next, we need to splice and edit these second audio signals that are effective for suppression to obtain a third audio signal, which can more effectively suppress the user's depressive symptoms. Finally, the third audio signal is played to the depressed user through the audio playback unit, and the synthesized audio is transmitted to the brain through bone conduction headphones to achieve feedback intervention treatment of the disease. By playing audio, the patient's nerves are in the most comfortable state, neurotransmitters are balanced, the function of the cerebral cortex is improved, the patient's symptoms are alleviated, and the patient's brain can get a good rest.

[0034] In one example, selecting a second audio signal set from the first audio signal set according to the brain wave analysis result includes:

[0035] Determine the EEG analysis result that satisfies the first preset condition, for example, the first preset condition refers to that the theta wave is within a reasonable normal range;

[0036] The first audio signal in the first audio signal set corresponding to the brain wave analysis result that meets the first preset condition is determined as the second audio signal set. The time when the θ wave is in a reasonable and normal range of brain waves is determined, and the first audio signal played at the same time is found, proving that the first audio signal played at this time is an effective signal for depression, that is, the second audio signal set.

[0037] In one example, splicing the second audio signal set into a third audio signal includes:

[0038] For every two adjacent second audio signals, a first sampling point and a second sampling point satisfying a second preset condition are selected from the adjacent second audio signals, the first sampling point and the second sampling point are located on different second audio signals, and the frequency of the first sampling point and the frequency of the second audio signal satisfy a third preset condition. The second preset condition is specifically a preset time interval. For example, two adjacent second audio signals are an A signal and a B signal, wherein the A signal is in front and the B signal is in the back. Then, an X sampling point is selected in the preset time interval at the tail of the A signal, and a Y sampling point is selected from the preset time interval at the head of the B signal. The frequency difference between the X sampling point and the Y sampling point is the smallest, that is, the third preset condition is satisfied. In actual operation, the frequency of each sampling point in the preset time interval at the tail of the A signal can be calculated, and the difference with the frequency of each sampling point in the preset time interval at the head of the B signal can be made in turn, and a pair of sampling points with the smallest difference can be selected, namely, the X sampling point and the Y sampling point.

[0039] The adjacent second audio signals are smoothed and sheared according to the first sampling point and the second sampling point. Specifically, the A signal and the B signal may be smoothed and sheared according to the X sampling point and the Y sampling point.

[0040] The smoothed and sheared adjacent second audio signals are spliced ​​to obtain the third audio signal. The smoothed and sheared A signal and B signal are directly spliced ​​together to obtain a third audio signal with a smooth and natural transition.

[0041] In an example, the smoothing and cutting of the adjacent second audio signal according to the first sampling point and the second sampling point includes:

[0042] The audio segment between the first sampling point and the second sampling point in the adjacent second audio signal is cut. Specifically, since the frequency difference between the X sampling point and the Y sampling point is the smallest, that is, the frequencies are closest, the X sampling point and the Y sampling point can be selected as the splicing position, so that the spliced ​​audio is relatively more natural and smooth, and the audio segment between the two splicing points is an invalid segment, so we need to cut the audio segment between the X sampling point and the Y sampling point.

[0043] The adjacent second audio signal after the audio segment is cut is smoothed. Specifically, since there is inevitably a frequency difference between the X sampling point and the Y sampling point, the cut audio signal needs to be smoothed. For example, when the X sampling point is 150 Hz and the Y sampling point is 230 Hz, the frequency of the final splicing point can be taken as an average of the two to be 190 Hz, and the segment before the X sampling point is smoothly decreased or increased, so that the final X sampling point is 190 Hz. Similarly, the segment after the Y sampling point is smoothly decreased or increased, so that the final Y sampling point is 190 Hz.

[0044] It will be apparent to those skilled in the art that the invention is not limited to the details of the exemplary embodiments described above and that the invention can be implemented in other specific forms without departing from the spirit or essential features of the invention. Therefore, the embodiments should be considered exemplary and non-limiting in all respects, and the scope of the invention is defined by the appended claims rather than the foregoing description, and it is intended that all variations falling within the meaning and scope of the equivalent elements of the claims be included in the invention. Any reference numeral in a claim should not be considered as limiting the claim to which it relates.
