Description

Technical Field

[0001] The present invention relates to the technical field of medical devices, and in particular to a hypnotic device that helps infants' brain development. Background Art

[0002] The quality of a child's sleep plays a crucial role in brain development. During sleep, the brain organizes and consolidates information learned and experienced during the day. High-quality sleep enhances memory, allowing children to better retain new knowledge and skills. Good sleep promotes connections between neurons and the pruning of synapses, making brain circuits more efficient and improving children's thinking and learning efficiency. During deep sleep, the body secretes growth hormone, which not only aids physical growth but also provides essential nutrients and support for brain development. High-quality sleep also regulates the balance of neurotransmitters in the brain, such as serotonin and dopamine, making children more emotionally stable and maintaining a positive mental state, which is conducive to healthy brain development. Conversely, poor sleep quality can disrupt the normal development of the brain and affect the development of multiple abilities, including cognition, learning, and emotions.

[0003] When infants and young children sleep, most are in a shallow sleep state, often waking and falling asleep, which brings many problems. Sleep is extremely important for the growth of infants and young children, and adequate sleep is the guarantee of physical development and brain health. However, shallow sleep leads to insufficient sleep, and infants and young children will be restless and cry frequently, which affects the secretion of growth hormone in the body, and can also make them lack a sense of security and affect their personality development. The development of brain tissue is of great significance to the intelligence and nervous system. Shallow sleep is not conducive to its normal development and may affect future learning and cognition. In addition, waking and falling asleep frequently can easily disrupt the sleep rhythm, affect normal metabolism, and increase the risk of disease. However, the infant pillows currently on the market have a single function, and most of them only have basic support. They do not take into account the special sleep needs of infants and young children, lack functions such as sleep aids to improve sleep quality, and are difficult to meet the needs of infants and young children for a good sleep.

[0026] like Figure 1-3As shown, an embodiment of the present invention provides a hypnosis device that helps the brain development of young children, including a single-chip microcomputer integrated controller 1 and a pillow body 14.

[0027] The massage pad 3 is located within the head groove 15, and the acupressure head massager 4 is disposed within the head groove 15 and at the lower end of the massage pad 3. A control display screen 7 and a heat dissipation mechanism 6 are disposed on both sides of the pillow body 14. A plurality of fixed wires 16 are fixedly disposed at the lower end of the top plate 12. The lower ends of the plurality of fixed wires 16 are fixedly connected to the music player doll 2. A 3D camera 5 is fixedly disposed at the four corners of the lower end surface of the top plate 12. The single-chip integrated controller 1, battery 10, and Bluetooth module 9 are all located within the pillow body 14. The USB power interface 11 and control switch 8 are both located outside the pillow body 14. A life status monitor 17 is embedded within the massage pad 3 and includes a piezoelectric film sensor, an optical fiber sensor, a micro accelerometer, and a temperature / humidity sensor. The surface of the massage pad 3 of the acupressure head massager 4 is divided into 36 pressure grids, each corresponding to an independently controlled micro electromagnetic drive unit.

[0028] A control system for a hypnotic device that helps children's brain development includes a control processing module, the control processing module is connected to a biosignal fusion module, a collaborative decision engine, and a cross-device synchronization module, and the biosignal fusion module is connected to a temporal memory network;

[0029] The biosignal fusion module uses the improved DS evidence theory and performs the following steps:

[0030] a. Assign a confidence weight of W1 (0.6-0.8) to the heartbeat signal of the piezoelectric film sensor, a weight of W2 (0.7-0.75) to the breathing signal of the optical fiber sensor, and a weight of W3 (0.5-0.6) to the posture signal of the micro accelerometer;

[0031] b. When the posture data of the accelerometer and the 3D camera 5 conflict, the credibility attenuation model is started: the accelerometer weight W3 is attenuated by 0.9n (n is the number of consecutive conflicts), and the 3D camera 5 data is used first.

[0032] The collaborative decision-making engine dynamically matches the collaborative control strategy of massage intensity, music beat and heat dissipation level based on the fused breathing, heartbeat and posture joint feature vector and the head point cloud data of the 3D camera 5.

[0033] The cross-device synchronization module uses an ultra-low frequency carrier (3.5Hz±0.2Hz) to synchronize the acoustic vibrations of the music player doll 2 with the mechanical pulses of the acupressure head massager 4. The collaborative decision engine has a built-in five-dimensional sleep state matrix, including:

[0034] Sleep stage classification unit: divided into light sleep (>0.4Hz), deep sleep (≤0.4Hz), and REM stage (respiratory variability>0.6) by the standard deviation of respiratory rate;

[0035] Posture deviation compensation unit: generates an asymmetric massage pressure distribution map based on the Euclidean distance d (unit: mm) between the center of mass of the head in the head slot 15 and the standard area, and the pressure value satisfies P = 0.4N × (d / 10);

[0036] Abnormal alarm unit: When the temperature and humidity gradient of the temperature / humidity sensor exceeds a threshold value (>2°C / min or humidity change rate>15%RH / min), the forced cooling mode of the heat dissipation mechanism 6 is triggered.

[0037] The network continuously records and analyzes the heart rate variability (HRV) baseline curve at the same time of day, the correlation weight between music type and sleep speed, and the response function of massage intensity and posture correction. It generates sleep pattern optimization suggestions every 24 hours and automatically adjusts control strategy parameters.

[0038] The Bluetooth module 9 supports the mixed reality interaction protocol, which enables the parent's mobile phone to display.

[0039] The surface of the massage pad 3 of the acupressure head massager 4 is divided into 36 pressure grids, each of which corresponds to an independently controlled micro electromagnetic drive unit. When the 3D camera 5 detects head deviation, the collaborative decision engine activates the electromagnetic drive unit of the target grid according to the deviation direction, so that the massage pressure value meets the following requirements:

[0040] P=P0+k×θ

[0041] Wherein: P0 is the basic pressure value, ranging from 0.3 to 0.5 N; k is the calibration coefficient, ranging from 0.05 N / degree; θ is the head offset angle, which is the angle between the line connecting the center of mass of the head and the standard position and the vertical axis (unit: degree) calculated by the 3D camera 5.

[0042] Music Player Doll 2 has a built-in brainwave induction algorithm library, including:

[0043] Alpha wave music group (8-12Hz): used in the early stages of falling asleep, the beat interval T is adjusted to T = 1 / (2f) according to the real-time breathing frequency f (Hz);

[0044] Theta wave music group (4-7Hz): used to maintain deep sleep, with the beat interval strictly synchronized with the exhalation duration;

[0045] Dynamic beat adjustment unit: automatically switches music groups when the standard deviation of breathing frequency exceeds 0.2Hz.

[0046] This system needs to have a dual-mode security protection mechanism, including a local watchdog circuit and a cloud monitoring relay:

[0047] The local watchdog circuit monitors the operating status of the single-chip integrated controller 1 and performs a hardware reset when a dead loop is detected; the cloud monitoring relay is connected to the home router through the Bluetooth module 9 and sends an early warning message to the preset guardian's mobile phone when the battery 10 power is lower than 20%.

[0048] The collaborative decision-making engine is connected to a biofeedback training unit that performs the following closed-loop training during the early stages of sleep onset:

[0049] a. Fine-tune the massage pressure parameter ΔP (±0.1N) every 5 minutes;

[0050] b. Monitor heart rate variability (HRV) for the next 3 minutes and calculate the HRV improvement rate η = (ΔHRV / HRV0) × 100%;

[0051] c. If η>5%, retain ΔP and update the personalized pressure-physiological response mapping table;

[0052] d. Optimize subsequent control parameters based on the mapping table.

[0053] Working principle:

[0054] The microcontroller integrated controller 1 is responsible for data processing and command issuance. A vital state monitor 17 is embedded within the massage cushion 3. A piezoelectric film sensor detects heartbeat, a fiber optic sensor detects breathing, a micro accelerometer detects body movement, and a temperature and humidity sensor monitors the environment. A 3D camera 5 scans the child's head position and posture in real time. The acupressure head massager has 436 independent electromagnetic drive units arranged in a grid, allowing for dynamic pressure adjustment. The music player doll 2 plays α / θ wave music synchronized with the massage pulses. A Bluetooth module 9 connects to the parent's phone for remote monitoring and interaction. The heat dissipation mechanism 6 automatically adjusts the wind speed based on temperature and humidity.

[0055] Sleep monitoring stage

[0056] After the child lies in the head slot 15, the life status monitor 17 starts working, and the piezoelectric film sensor detects the heartbeat signal. The optical fiber sensor captures the chest rise and fall and calculates the respiratory rate. The accelerometer monitors body movement to determine whether the child turns over or wakes up. The data is transmitted to the bio-signal fusion module in real time, and the improved DS evidence theory is used for data fusion to eliminate noise interference. The 3D camera 5 scans the head point cloud data every 10 seconds and calculates the coordinates of the head center of mass (to determine whether it deviates from the standard position). The head tilt angle θ is used to dynamically adjust the massage pressure.

[0057] The collaborative decision-making engine divides sleep stages based on respiratory variability:

[0058] Light sleep (respiratory rate > 0.4Hz) → Play alpha wave music (8-12Hz) and initiate a gentle massage (P = 0.3N). Deep sleep (respiratory rate ≤ 0.4Hz) → Switch to theta wave music (4-7Hz) and reduce the massage intensity (P = 0.2N). REM sleep (respiratory variability > 0.6) → Maintain theta wave music and pause the massage to avoid disturbing dreams. If head deviation is detected (θ > 5°), adjust the pressure according to the formula P = P0 + k × θ: P0 = 0.3N (baseline value), k = 0.05N / degree (calibration factor).

[0059] While embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions, and variations may be made to these embodiments without departing from the principles and spirit of the invention, and that the scope of the invention is defined by the appended claims and their equivalents.
