Description

Technical Field

[0001] The present invention relates to the field of musical instruments, and in particular to an intelligent terminal and system for preventing and delaying Alzheimer's disease. Background Art

[0002] Alzheimer's disease is an incurable neurodegenerative disease and the most common type of dementia. Its main clinical features are progressive cognitive dysfunction and behavioral disorders. It seriously threatens people's daily life and health and brings a heavy economic burden to society and families.

[0003] According to the paper "Comparison of the Effects of Various Intervention Measures for Alzheimer's Disease - Based on Bayesian Network Meta-Analysis" (2020), among the various cognitive intervention measures for intervening in the cognitive function of patients with dementia, the best effect is nursing intervention (SUCRA=80.2%), followed by music therapy (SUCRA=72.2%), physical exercise (SUCRA=62.3%), cognitive rehabilitation (SUCRA=57.3%), cognitive stimulation therapy (SUCRA=34.5%), computer cognitive training (SUCRA=33.4%), and psychosocial intervention (SUCRA=31.4%). The effect of drug intervention is the worst (SUCRA=28.7%).

[0004] In response to this disease, a research team at the Massachusetts Institute of Technology published a paper in Nature in 2016. Its main point is: 40 Hz sound and light stimulation can eliminate beta-amyloid protein in the brain of mice and delay the damage of Alzheimer's disease to the brain. In addition, in a recent paper (2024), the mechanism of 40 Hz sound and light stimulation was disclosed - stimulating the brain's glymphatic network and accelerating the cerebrospinal fluid to "wash away" pathogenic protein deposits.

[0005] On the basis of the above research, combined with the experience of the historical research project ("Research on the Correlation between Mild Cognitive Impairment and Hearing Function in Community Elderly People"), the inventor intends to further optimize the ongoing project ("Research on the Impact of Percussion Ensemble on Apathy Symptoms in Patients with Alzheimer's Disease"), in the hope of achieving the goal of using multiple complex means to intervene in patients with mild Alzheimer's disease, which can effectively delay the deterioration of the disease.

[0006] Currently, only a few instruments can reach the standard of emitting 40Hz sound waves. 20Hz-40Hz is called extremely low frequency, and probably only instruments such as double bass, contrabassoon, tuba, organ, piano, etc. can reach such a low range. 40Hz-80Hz is called low frequency, mainly including bass drum, double bass, cello, contrabassoon, bassoon, bass trombone, bass clarinet, tuba, French horn, etc.

[0007] The inventor combined the characteristics of percussion instruments and selected the African drum as an instrument to train Alzheimer's patients. During the training process, multi-sensory stimulation combined with music, images, etc. can achieve certain effects. However, due to the limitations of the patient's own ability and the characteristics of the African drum itself, it is extremely difficult to accurately and massively emit 40Hz sound waves.

[0008] The structure of the African drum is extremely simple. The main part of the African drum is made of wood. It can be wood or other materials, but it is usually for the transmission and resonance of sound. The inside of the drum body is hollow, one side is open for sound, and the other side is closed as the drum head. The design of the drum body is usually thin waist, thick upper body, and thin lower body. The drum head is generally made of goat skin, cowhide or pig skin, which have good elasticity and can withstand vibration when struck. The drum head is usually fixed on the open surface of the drum body, and the drum head is fixed in the appropriate position through the cooperation of the drum rope and the drum hoop. The way of striking the African drum varies according to the pitch of the drum. The bass drum (B) is usually struck with the whole palm, the alto drum (T) is struck with four fingers, and the treble drum (S) is struck obliquely with the base of the four fingers. These striking methods are related to the position of the drum head, which is usually marked on the rhythm spectrum, guiding the performer how to strike to produce a specific timbre (generally called "three notes") and rhythm.

[0009] Under this premise, how to make the African drum emit 40Hz sound waves with low difficulty and more effectively is an urgent problem to be solved. Therefore, there is an urgent need for an intelligent terminal and system for preventing and delaying Alzheimer's disease, which can reduce the difficulty of use for patients and emit 40Hz sound waves more effectively, so as to achieve the purpose of effectively preventing and delaying Alzheimer's disease. Summary of the invention

[0010] The present invention provides an intelligent terminal and system for preventing and delaying Alzheimer's disease, which can reduce the difficulty of use for patients and emit 40 Hz sound waves more effectively to achieve the purpose of effectively preventing and delaying Alzheimer's disease.

[0011] In order to solve the above technical problems, this application provides the following technical solutions:

[0012] An intelligent terminal for preventing and delaying Alzheimer's disease, comprising:

[0013] A drum body, the drum body comprises a pressure ring, a drum body and a drum surface, the drum body is a vertical hollow structure, the drum surface covers the open end of the drum body, the pressure ring is fitted onto the drum body and presses the drum surface, a plurality of vertical slide grooves are provided on the drum body, the slide grooves are located below the pressure ring, a slider slidably connected to the slide grooves is provided in the slide grooves, a driving mechanism for driving the slider to move up and down is provided on the drum body, the sliders are respectively fixed to the edges of the drum surface, a pressing state detection piece is provided at the position where the drum body contacts the pressure ring, the base end of the pressing state detection piece is fixed to the drum body, two contacts are provided below the free end of the pressing state detection piece, the two contacts are embedded in the drum body, and the two contacts are turned on when the pressing state detection piece is pressed;

[0014] A vibration monitoring module, which is fixedly connected to the drum body and is used to collect sound signals emitted by the drum surface;

[0015] An instruction input module, used for receiving a calibration signal input by a user;

[0016] A control module is used to receive a sound signal, obtain the frequency information therein, and then analyze the proportion of the 40Hz frequency therein. If the proportion is lower than a preset value, an offset prompt message is generated. When a calibration signal is received, it is determined whether the vibration frequency in the frequency information is higher than 40Hz. If it is higher than 40Hz, a loosening signal is generated; if it is lower than 40Hz, a tightening signal is generated; if the proportion is higher than a preset value, a normal working signal is generated; two contacts are respectively connected to the control module, and the control module is also used to send a loosening signal or a tightening signal after the two contacts are disconnected;

[0017] A visible light projection module, which is fixed in the drum body and is used to emit visible light of 40 Hz at a preset angle according to a first preset mode to illuminate the drum surface in a preset area when receiving a normal working signal, and to emit visible light according to a second preset mode when receiving an offset prompt message;

[0018] The driving mechanism is connected to the control module signal, and the driving mechanism is used to move upward when receiving a loosening signal, and move downward when receiving a tightening signal.

[0019] The principle and effect of this solution are as follows: the drum body is the most basic drum structure, and the drum surface is struck so that the drum surface vibrates and makes a sound. The size of the sound vibration is directly related to the force of the strike, and the frequency of the sound vibration is related to the size, shape, material and way of striking the drum surface. After the strike is completed, the vibration monitoring module can collect the frequency information of the sound emitted by the drum surface and send it to the control module. The control module receives and analyzes the proportion of the 40Hz frequency in the frequency information. If it is lower than the preset value, it indicates that the drum surface does not meet the standard (due to use or aging, etc., it cannot normally emit a 40Hz sound with a higher proportion). Therefore, the control module generates an offset prompt message at this time. After receiving the offset prompt message, the visible light projection module emits visible light according to the second preset mode, thereby reminding the user of this situation.

[0020] If the user wants to make adjustments so that the drumhead emits as many 40Hz frequency sounds as possible when struck, a calibration signal can be input through the command input module (if the user is not ready to make adjustments for the time being, the above logic ends). At this time, the control module determines whether the vibration frequency of the collected sound information is higher than 40Hz or lower than 40Hz. When it is higher, in most cases the drumhead is too tight, resulting in a higher vibration frequency; when it is lower, in most cases the drumhead is too tight, resulting in a lower frequency. Therefore, a loosening signal or a tightening signal is generated for the corresponding situation, but at this time, the drive mechanism is not directly controlled to work.

[0021] When the user is ready to adjust the tightness of the drum surface, the user needs to remove the pressure ring (regardless of whether the pressure ring is in the form of a strapping method similar to a cable tie, or the traditional method of directly fixing by shape). After the pressure ring is removed, the compression state detection piece disconnects the two contacts under the action of its own elastic force. At this time, the control module receives a signal that the two contacts are disconnected, and then sends a loosening signal or a tightening signal to the drive mechanism. When the drive mechanism receives the loosening signal or the tightening signal, it moves up or down to adjust the drum surface. After the adjustment is in place, the user presses the pressure ring again to fix the drum surface, completing all adjustments to the drum surface.

[0022] In normal conditions, the visible light projection module can emit 40Hz visible light at a preset angle according to the first preset mode to illuminate the drum surface in a preset area, which can not only let the user know the working status of the drum surface, but also guide the user to strike the appropriate area, reducing the user's difficulty of use and increasing the proportion of 40Hz sound after striking. The visible light projection module emits 40Hz visible light, so when the patient observes the striking position, he can also receive visible light stimulation more attentively.

[0023] In summary, the present invention uses the vibration monitoring module to obtain the vibration of the drum surface after each strike, and uses the visible light projection module to prompt whether the drum surface needs to be adjusted, which quickly helps the user to increase the proportion of 40Hz sound, reducing the difficulty of use for patients. In addition, the visible light projection module can guide the patient to better strike the drum surface, further reducing the difficulty of use for the patient, so that the patient can effectively emit 40Hz sound waves.

[0024] Furthermore, a magnetic body capable of adsorbing the pressing state detection sheet is embedded inside the pressing ring.

[0025] Such a design enables the user to further separate the pressing state detection sheet from the two contacts when taking out the pressing ring. An insulating layer is provided on the back side of the pressing state detection sheet that is not in contact with the two contacts.

[0026] The insulation performance is guaranteed, and the compression status detection piece can be protected.

[0027] Furthermore, a countersunk hole for accommodating the compression state detection sheet and two contacts is provided on the side of the drum body.

[0028] It can better ensure the flatness of the side of the drum body (when the installation is completed).

[0029] Furthermore, the control module is also used to obtain amplitude information in the sound signal, compare the amplitude information with a preset motion standard value, and generate an aggravated prompt signal if the amplitude information is lower than the motion standard value; if the amplitude information is higher than the motion standard value, generate a success prompt signal; and send the aggravated prompt signal or the success prompt signal to the visible light projection module; the visible light projection module is used to emit light according to a preset aggravated prompt mode after receiving the aggravated prompt signal; the visible light projection module is used to emit light according to a preset success prompt mode after receiving the success prompt signal.

[0030] This method can give patients more opportunities to exercise while beating the drum. By detecting amplitude information, it can help patients better participate in exercise and be more in line with the intervention measure of physical exercise.

[0031] Furthermore, the vibration monitoring module and the visible light projection module are respectively fixedly mounted on the side walls inside the drum body.

[0032] This method is more convenient to install.

[0033] Furthermore, the control module is also used to obtain frequency information of the acquired sound signal after Fourier transformation when the acquired amplitude information exceeds a preset processing standard value.

[0034] This method can obtain frequency information more accurately and quickly.

[0035] Furthermore, an electric telescopic rod is provided in the drum body, one end of which is in contact with the inner side of the drum surface, and the electric telescopic rod is fixed to the side wall of the drum body; the control module is also used to receive a calibration signal, generate a loosening signal or a tightening signal, and after not detecting that the two contacts are disconnected within a preset waiting time, send an extension signal or a retraction signal to the electric telescopic rod; the electric telescopic rod is also used to perform an extension action or a retraction action of a preset distance accordingly after receiving an extension signal or a retraction signal.

[0036] The pitch of the drum surface is also related to the size of the drum surface when it vibrates freely. When the patient cannot adjust with the help of external force, the entire terminal can also perform intelligent self-adjustment within a certain range, making it more convenient for users to calibrate and use.

[0037] An intelligent system for preventing and delaying Alzheimer's disease adopts the above-mentioned terminal.

[0038] Furthermore, it also includes a Bluetooth module and a user terminal, the Bluetooth module is connected to the control module signal, and the control module is also used to send amplitude information and frequency information to the user terminal.

[0039] This method can better summarize and report the patient's overall condition. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] The symbols in the drawings of the specification include: a drum body 21 , a pressing state detection sheet 31 , a slider 41 , a visible light projection module 51 , and an instruction input module 61 .

[0044] Embodiment 1

[0045] A smart terminal (such as a smart terminal for preventing and delaying Alzheimer's disease) of this embodiment Figure 1 , Figure 2As shown), it includes: a drum body, a vibration monitoring module (actually similar to a pickup, or a microphone), a command input module 61 (a button switch is selected in this embodiment), a control module (the STC12C5A60S2 single-chip microcomputer is selected in this embodiment, and its crystal oscillator frequency is relatively high at 22.1184 MHz, which can meet the requirements of fast Fourier transform), and a visible light projection module 51 (actually, multiple light-emitting LEDs can be used. If the power requirement is large, an external power supply can be used, and the single-chip microcomputer controls whether the light-emitting LED power supply circuit is turned on).

[0046] The drum body includes a pressure ring (not shown), a drum body 21 and a drum surface (not shown), wherein the drum body 21 is a vertical hollow structure, and the drum surface covers the open end of the drum body 21, and the pressure ring is sleeved on the drum body 21 and presses the drum surface, and the drum body 21 is provided with a plurality of vertical slide grooves, wherein the slide grooves are located below the pressure ring, and a slider 41 is provided in the slide grooves and is slidably connected to the slide grooves, and the drum body 21 is provided with a driving mechanism (not shown, a linear motor or a motor + reducer + worm gear can be selected, and the specific structure needs to consider the material of the drum surface), and the slider 41 is fixed to the edge of the drum surface respectively, and a compression state detection piece 31 (actually a simple reed) is provided at the position where the drum body 21 contacts the pressure ring, and the base end of the compression state detection piece 31 is fixed to the drum body 21, and the compression state detection piece 31 Two contacts (simple copper contacts are sufficient) are provided below the free end, and the two contacts are embedded in the drum body 21. The two contacts are turned on when the clamping state detection piece 31 is clamped (i.e., the reed itself is conductive, and even if the clamping ring needs to adjust its position, as long as the length of the reed is sufficient, the standard clamping ring state can be successfully reached); a magnetic body capable of absorbing the clamping state detection piece 31 is embedded on the inner side of the clamping ring; a vibration monitoring module is fixedly connected to the drum body 21, and the vibration monitoring module is used to collect sound signals emitted by the drum surface; an instruction input module 61 is used to receive calibration signals input by the user; a magnetic body capable of absorbing the clamping state detection piece 31 is embedded on the inner side of the clamping ring; an insulating layer is provided on the back side of the clamping state detection piece 31 that is not in contact with the two contacts; a countersunk hole for accommodating the clamping state detection piece 31 and the two contacts is provided on the side of the drum body 21. The vibration monitoring module and the visible light projection module 51 are respectively fixedly mounted on the side walls inside the drum body 21.

[0047] The control module is used to receive the sound signal, obtain the frequency information therein, and then analyze the proportion of the 40Hz frequency therein. If the proportion is lower than the preset value (which can be set to 40% in this embodiment), an offset prompt message is generated, and when the calibration signal is received, it is determined whether the vibration frequency in the frequency information is higher than 40Hz. If it is higher than 40Hz, a loosening signal is generated; if it is lower than 40Hz, a tightening signal is generated; if the proportion is higher than the preset value, a normal working signal is generated; the two contacts are respectively connected to the control module (in fact, the pins of the single-chip microcomputer are respectively connected to the two contacts), and the control module is also used to send a loosening signal after the two contacts are disconnected. The visible light projection module 51 is fixed in the drum body 21, and is used to emit 40Hz visible light (this can be purchased directly or customized, and the flashing frequency control of LED is a mature technology) at a preset angle according to a first preset mode (in this embodiment, the green light is on) to illuminate the drum surface in a preset area when a normal working signal is received, and emit visible light according to a second preset mode (in this embodiment, the red light is on) when an offset prompt message is received; wherein the drive mechanism is connected to the control module signal, and the drive mechanism is used to move upward when a loosening signal is received, and move downward when a tightening signal is received.

[0048] The control module is also used to obtain amplitude information in the sound signal, compare the amplitude information with the preset motion standard value, and generate an aggravation prompt signal if it is lower than the motion standard value; if it is higher than the motion standard value, generate a success prompt signal; and send the aggravation prompt signal or the success prompt signal to the visible light projection module 51; the visible light projection module 51 is used to emit light according to the preset aggravation prompt mode after receiving the aggravation prompt signal (in this embodiment, the yellow light is on); the visible light projection module 51 is used to emit light according to the preset success prompt mode after receiving the success prompt signal (in this embodiment, the blue light is on).

[0049] During specific use, the user (of course, the user can also give it to the patient after adjustment) first strikes the drum surface to make the drum surface vibrate and make a sound. After the striking is completed, the vibration monitoring module can collect the frequency information of the sound emitted by the drum surface and send it to the control module. The control module receives and analyzes the proportion of the 40Hz frequency in the frequency information. If it is lower than the preset value, it indicates that the drum surface does not meet the standard (due to use or aging, etc., it cannot normally emit a 40Hz sound with a higher proportion). Therefore, the control module generates an offset prompt information at this time. After receiving the offset prompt information, the visible light projection module 51 emits visible light according to the second preset mode, that is, it emits red light.

[0050] At this time, the user is ready to calibrate and inputs a calibration signal through the instruction input module 61 (if the user is not ready to adjust temporarily, the above logic ends). At this time, the control module determines whether the vibration frequency of the collected sound information is higher than 40Hz or lower than 40Hz. When it is higher, in most cases the drum surface is too tight, resulting in a higher vibration frequency; when it is lower, in most cases the drum surface is too tight, resulting in a lower frequency. Therefore, a loosening signal or a tightening signal is generated for the corresponding situation.

[0051] Then, the user needs to remove the pressing ring. After the pressing ring is removed, the pressing state detection sheet 31 disconnects the two contacts under the action of its own elastic force. At this time, the control module receives a signal that the two contacts are disconnected, and sends a loosening signal or a tightening signal to the driving mechanism. When the driving mechanism receives the loosening signal or the tightening signal, it moves up or down to adjust the drum surface. After the adjustment is in place, the user presses the pressing ring again to fix the drum surface, completing all adjustments to the drum surface.

[0052] This embodiment also discloses an intelligent system for preventing and delaying Alzheimer's disease, which uses the above-mentioned terminal.

[0053] Embodiment 2

[0054] The difference between this embodiment and the first embodiment is that in this embodiment, the control module is further used to obtain the frequency information of the acquired sound signal after Fourier transformation when the acquired amplitude information exceeds the preset processing standard value.

[0055] Embodiment 3

[0056] Compared with the first embodiment, the only difference is that an electric telescopic rod is further provided in the drum body 21, one end of the electric telescopic rod is in contact with the inner side of the drum surface, and the electric telescopic rod is fixed to the side wall of the drum body 21; the control module is also used for receiving a calibration signal, generating a loosening signal or a tightening signal, and after not detecting that the two contacts are disconnected within a preset waiting time, sending an extension signal or a retraction signal to the electric telescopic rod; the electric telescopic rod is also used for performing an extension action or a retraction action of a preset distance (the smallest action unit, which is 5 mm in this embodiment) accordingly after receiving the extension signal or the retraction signal.

[0057] During specific use, if the pressure ring cannot be removed temporarily, the electric telescopic rod will extend or retract according to the result of the frequency signal, realizing intelligent self-adjustment, which is more convenient for users.

[0058] Embodiment 4

[0059] Compared with the system in the first embodiment, the only difference is that it further includes a Bluetooth module and a user terminal, the Bluetooth module is connected to the control module signal, and the control module is also used to send amplitude information and frequency information to the user terminal.

[0060] In specific use, it actually means summarizing the patient's operation logs for the convenience of statistical analysis.
