Description

Technical Field

[0001] The present application relates to the technical field of motion sickness intervention and vestibular inhibition, and in particular to a motion sickness intervention device based on vestibular inhibition. Background Art

[0002] With the popularization of the Internet, smart phones, and the fifth generation of mobile communication technology, people often choose to use their mobile phones to enrich their riding time or use laptops to work when riding various means of transportation. However, some passengers may experience motion sickness when using the above devices while on the move.

[0003] Motion sickness, also known as carsickness, seasickness, and airsickness, refers to a disease caused by a loss of balance when riding in various means of transportation. It is generally believed that when the movement felt by the senses such as vision, muscles, and joints is inconsistent with the movement felt by the vestibular system, it causes symptoms such as dizziness, nausea, vomiting, and loss of appetite. In severe cases, it may manifest as a feeling that the house and objects are spinning, inability to stand, and even fainting.

[0004] Vestibular inhibition is the main means of intervening motion sickness, and there are two types of methods on the market. The first is drug intervention. Common drugs include: dimenhydrinate (Chengyunning), diphenhydramine (Benadryl), and diazepam (Valium). Drugs inhibit the vestibular system by blocking receptors or enhancing neurotransmitters, but they have a slow onset of action and have side effects such as drowsiness, dry mouth, and blurred vision. Some people are insensitive to the drugs. The second is multi-channel electrical stimulation to inhibit vestibular nerve activity. Although this method is fast-acting, it has disadvantages such as inconvenient application of conductive paste and poor pain tolerance, and has not been widely used. In summary, the existing methods of inhibiting vestibular activity have defects in timeliness, safety, convenience, and effectiveness. Summary of the invention

DETAILED DESCRIPTION

[0019] The following describes the embodiments of the present application through specific examples, and those skilled in the art can easily understand other advantages and effects of the present application from the contents disclosed in this specification. The present application can also be implemented or applied through other different specific embodiments, and the details in this specification can also be modified or changed in various ways based on different viewpoints and applications without departing from the spirit of the present application. It should be noted that the following embodiments and features in the embodiments can be combined with each other without conflict.

[0020] The specific implementation of the present application is further described in detail below in conjunction with the drawings and examples.

[0021] This application uses cold stimulation and monaural stimulation to achieve vestibular inhibition and thus intervene in motion sickness. The physiological basis includes: The vestibular system is an important sensory system in the human body, mainly responsible for balance, spatial positioning and motion perception. It is located in the inner ear and is mainly composed of the otoliths, semicircular canals and snails. The otoliths are responsible for sensing linear acceleration, and the semicircular canals are responsible for sensing rotational motion. The vestibular system transmits information to the brain through the vestibular nerve to help maintain balance and coordinate movements.

[0022] Motion sickness is an uncomfortable symptom caused by the inconsistency between perceived movement and the vestibular, visual and somatosensory information in the inner ear. Inhibiting vestibular activity can reduce the intensity of incoming vestibular information, thereby reducing the conflicting signals received by the brain and intervening in motion sickness. Reducing the excitability of the vestibular nerves can help reduce the brain's sensitivity to movement, thereby reducing the symptoms of nausea and dizziness and intervening in motion sickness.

[0023] Vestibular inhibition caused by cold stimulation. Cold stimulation applied to the external auditory canal can be transmitted to the vestibule. Specifically, the low temperature environment will affect the function of sodium and potassium ion channels on the neuronal membrane between the vestibule and the cerebral cortex, reducing the probability of opening, hindering the generation and conduction of action potentials, and affecting the recovery and repolarization process of neurons; Low temperature slows down the metabolic activity of cells, including neurons, and reduces enzyme activity and energy generation in cells, which leads to a decrease in neuronal excitability and difficulty in maintaining high-frequency electrical activity, further inhibiting the overall activity of the vestibular system. A low temperature environment will cause the temperature of the inner ear fluid, including lymph, to drop, increasing its viscosity, which in turn affects the flow of fluid in the semicircular canals. The reduced fluidity will inhibit the vestibular ability to perceive movement.

[0024] Monaural stimulation can further enhance the vestibular inhibition effect. Specifically, it includes: Receiving audio information with one ear causes a reallocation of cognitive resources, resulting in an attention distraction effect; when the information received by the two ears is unequal, the auditory nucleus of the thalamus and the auditory cortex of the temporal lobe will obtain more resources to process the audio information, and the brain will pay less attention to abnormal vestibular signals, thereby enhancing the vestibular inhibition effect.

[0025] Receiving audio information with one ear has a masking effect. Auditory information and vestibular information share neural pathways in the vestibular nucleus and cochlear nucleus of the brainstem and the auditory nucleus of the thalamus. Sufficient auditory nerve electrical signals will mask the somatosensory nerve electrical signals, thereby enhancing the vestibular inhibition effect.

[0026] Monaural stimulation using soothing music can relieve the anxiety and tension caused by motion sickness. The physiological evidence includes: Soothing music can relieve the anxiety and tension caused by motion sickness. Soothing music can reduce the activity of the sympathetic nervous system and activate the parasympathetic nervous system, thereby inducing the body's relaxation response; it can reduce the level of cortisol in the body, reduce the body's response to stress, and help relieve anxiety and tension.

[0027] Soothing music: The beat rate is controlled at 60-80BPM to match the human heart rate; the frequency is concentrated between 250-2000Hz to avoid harshness; use even harmonics to smooth the sound; use progressive envelope to avoid sudden volume changes, and you can choose the song Largo from Winter by Antonio Vivaldi; the noise generated by driving vehicles is between 50-90 decibels, and the music playback volume is 75 decibels, which can ensure that it can be heard clearly in most cases; according to the "Environmental Noise Guidelines for the European Region" issued by the World Health Organization, the maximum allowable noise time is no more than 127 hours per week at 75 decibels. Except in extreme cases, 75 decibels of soothing music will not affect hearing.

[0028] The present application embodiment provides a motion sickness intervention device based on vestibular inhibition, such as Figure 1 and Figure 2 As shown, the motion sickness intervention device based on vestibular inhibition includes a flexible Peltier cooling sheet 100, a temperature control unit 200, a music playing unit 300, a control unit 400 and a temperature sensor 500; wherein, the flexible Peltier cooling sheet 100 is arranged on one side of the music playing unit 300 and covers the auricle, the music playing unit 300 is used to be worn on the ear, the temperature sensor 500 is arranged on the music playing unit 300, the signal output end of the temperature sensor 500 is connected to the signal input end of the temperature control unit 200, the signal output end of the temperature control unit 200 is connected to the signal input end of the flexible Peltier cooling sheet 100, and the control unit 400 is connected to the music playing unit 300 signal to control the music playing unit 300 to play audio data.

[0029] In this embodiment, the temperature sensor 500 and the temperature control unit 200 may be connected by wires, and the temperature control unit 200 may be embedded in the music playing unit 300 .

[0030] Exemplarily, the flexible Peltier cooling sheet 100 is an electronic component that uses the Peltier effect for cooling. When direct current passes through a thermoelectric element composed of n-type and p-type semiconductor materials, a temperature difference is generated, causing the temperature on one side of the current flow direction to decrease (cooling side) and the temperature on the other side to increase (heat dissipation side); the model FPA-1 can be selected, with a maximum temperature difference of 60°C, a thickness between 0.5-1.0mm, a power supply voltage of 5V, and a maximum cooling power of 5w, which is suitable for working under non-heat dissipation conditions; the front end of the flexible Peltier cooling sheet 100 is a hollow cylinder, and the distance of probing into the ear canal can be customized according to the shape and size of the user's ear canal without damaging the eardrum. The rear end is in the shape of an earmuff and can wrap the entire auricle; the inner side is engraved with threads, which can be fastened to the music playback unit 300 by threads.

[0031] In some embodiments, Figure 1 and Figure 3 As shown, a thread 301 is provided at the front end of the music playing unit 300 , a threaded hole 101 is provided in the middle of the flexible Peltier cooling sheet 100 , and the flexible Peltier cooling sheet 100 is installed at the front end of the music playing unit 300 by cooperating with the threaded hole 101 through the thread 301 .

[0032] In some embodiments, a heat dissipation unit may be added to the music playback unit 300, and a heat dissipation fan may be installed at the outermost end of the music playback unit 300 to provide a better environment for the operation of the device.

[0033] Exemplarily, the output voltage of the temperature sensor 500 is linearly related to the temperature. Model LM35 can be selected, and its output voltage increases by 10mV for every 1°C increase in temperature. The measurement temperature range is between -40°C and 125°C. With a 10-bit ADC, the resolution is 0.1°C. The analog temperature sensor will be placed at the front end of the music playback unit 300, or the insertion distance can be customized according to the shape and size of the user's ear canal without damaging the eardrum to monitor the temperature inside the ear canal.

[0034] In some embodiments, Figure 1 and Figure 4 As shown, the control unit 400 includes a shell 401, a control chip 402, a membrane button 403 and a knob 404, the control chip 402 is arranged in the shell 401, the membrane button 403 and the knob 404 are electrically connected to the control chip 402, the membrane button 403 and the knob 404 are arranged on the outside of the shell 401, and the control unit 400 is connected to the temperature control unit 200 by line, wherein the membrane button 403 is used to start or shut down the control chip 402, and the knob 404 is used to adjust the target control temperature of the temperature control unit 200.

[0035] The control unit 400 is used to control the entire device to implement motion sickness intervention. The control process can be configured in the control chip 402 for implementation. In some embodiments, such as Figure 5 As shown, this is the control flow chart of the control chip, combined with Figure 4 , the control chip 402 is configured to execute the following steps S501~S504.

[0036] S501: Acquire a first control signal fed by a membrane key; wherein the first control signal includes a start signal and a stop signal.

[0037] S502: When the first control signal is a start signal, the temperature control unit is controlled to work and the music playing unit is controlled to play audio data. When the temperature control unit is working, based on the ear canal temperature collected in real time by the temperature sensor and the target control temperature, the flexible Peltier cooling sheet is controlled to work so that the ear canal temperature is within the target control temperature range. The audio data can be pre-stored in the control chip.

[0038] S503: When the temperature control unit is in working state, a second control signal fed by the knob is acquired in real time, and the target control temperature is adjusted based on the second control signal.

[0039] S504: When the first control signal is a shutdown signal, the temperature control unit is controlled to stop working and the music playing unit is controlled to stop playing audio data.

[0040] In another embodiment, the audio data played can be provided by a smart phone, which can provide more audio data. When the target object feels the symptoms of motion sickness, the membrane button 403 is pressed to start the device, the temperature control unit 200 outputs the maximum current to the flexible Peltier cooling sheet 100, applies cold stimulation to the vestibule, and the music playing unit 300 plays audio with a sufficiently loud volume to one ear, which is preset to be 75dB soothing music; the temperature control unit 200 can adjust the current size in proportion to the degree to which the user rotates the knob 404. If the user does not take any action (i.e., the initial state of the knob 404), the temperature in the ear canal is monitored by the temperature sensor 500 according to the preset target control temperature of 20°C, and the temperature control unit 200 adjusts the output current size by comparing the ear canal temperature with the target control temperature; after the target object believes that the motion sickness has been suppressed, the membrane button 403 is pressed again to pause the device, the temperature control unit 200 cuts off the current output, and the flexible Peltier cooling sheet 100 and the music playing unit 300 stop working.

[0041] When the temperature control unit 200 is working, the temperature in the ear canal is maintained in the following manner: the flexible Peltier cooling sheet 100 is controlled to work at a set current value; if the ear canal temperature acquired in real time by the temperature sensor 500 is lower than the target control temperature, the working current value of the flexible Peltier cooling sheet 100 is increased; if the ear canal temperature acquired in real time by the temperature sensor 500 is higher than the target control temperature, the working current value of the flexible Peltier cooling sheet 100 is reduced.

[0042] In actual implementation, the target control temperature is a range threshold. If the knob 404 is in an initial state, that is, the user does not operate the knob 404, the target control temperature may be 20±0.05°C.

[0043] In some embodiments, Figure 6 As shown, the motion sickness intervention device based on vestibular inhibition also includes a sound intensity sensor 600, which is signal-connected to the control chip 402. The sound intensity sensor 600 is used to collect the strength of the external noise signal. The control chip 402 controls the intensity of the audio data played by the music playback unit 300 based on the strength of the external noise signal, so that the intensity of the played audio data is at least greater than the strength of the external noise signal collected in real time.

[0044] It should be noted that when the intensity of the audio data is controlled based on the sound intensity sensor 600, the maximum intensity of the played audio data cannot exceed a set safety threshold to avoid damage to the user's hearing.

[0045] Preferably, in the above-mentioned motion sickness intervention device based on vestibular inhibition, when the knob is in the initial state, the target control temperature is 20°C.

[0046] In some embodiments, Figure 7 As shown, the motion sickness intervention device based on vestibular inhibition also includes a motion sickness monitoring unit 700, which is connected to the control chip 402 by signal. The motion sickness monitoring unit 700 is used to monitor the physiological signal of the target object, and when the physiological signal of the target object reaches a threshold or the digital characteristics have motion sickness performance, a start signal is sent to the control chip 402, and after the physiological signal or digital characteristics of the target object subside, a shutdown signal is sent to the control chip 402.

[0047] In summary, the motion sickness intervention device based on vestibular inhibition has the following beneficial effects.

[0048] 1) It is proposed to inhibit vestibular activity by applying cold stimulation. After the target subject feels the onset of motion sickness, a flexible Peltier cooling sheet is used to reduce the ear canal temperature to achieve vestibular inhibition; the shortcomings of slow effect and side effects of drugs are solved, and the shortcomings of cumbersome operation and pain of electrical inhibition are solved. The goal of effectively and comfortably intervening in motion sickness is truly achieved.

[0049] 2) It is proposed to further suppress vestibular activity by applying monaural stimulation. On the basis of cold stimulation, by playing sufficiently loud audio to one ear, the vestibular inhibition effect can be strengthened and the inhibition time can be shortened.

[0050] 3) It is suggested to use soothing music as audio with sufficient loudness to relieve emotions. Motion sickness is accompanied by negative emotions such as tension and anxiety. Playing soothing music can weaken the activity of the sympathetic nervous system and activate the parasympathetic nervous system, thus inducing the body's relaxation response. It can also reduce the level of cortisol in the body, reduce the body's response to stress, help relieve motion sickness anxiety and tension, and make the target feel comfortable.

[0051] The above implementation modes are only used to illustrate the present application, and are not intended to limit the present application. Ordinary technicians in the relevant technical field may make various changes and modifications without departing from the spirit and scope of the present application. Therefore, all equivalent technical solutions also belong to the scope of the present application, and the scope of patent protection of the present application shall be limited by the claims.
