Description

Technical Field

[0001] This invention relates to the field of neonatal medical monitoring and nursing technology, specifically to a smart bracelet for monitoring neonatal jaundice. Background Technology

[0002] Neonatal jaundice is one of the most common clinical problems in newborns. Excessively high bilirubin levels are neurotoxic, and if not detected and intervened in time, can lead to acute bilirubin encephalopathy, causing irreversible neurological damage, such as kernicterus. Among the early clinical manifestations of acute bilirubin encephalopathy, lethargy is a crucial warning sign. It manifests as abnormally prolonged sleep time, excessively deep sleep, and difficulty in waking the newborn, directly reflecting the neurotoxic effects of bilirubin on the central nervous system.

[0003] Currently, in clinical practice and home monitoring, the monitoring of neonatal jaundice and sleep status is usually carried out independently and separately. The main technical solutions are as follows: There are mature transcutaneous jaundice detectors on the market, such as products from companies like Shenzhen Jingbo Medical. These devices use specific wavelengths of light, such as 450nm blue light and 550nm green light, to non-invasively estimate serum bilirubin concentration based on the reflectivity of skin tissue. However, these devices are limited in function and can only provide isolated bilirubin values. They cannot be correlated with or assessed for neurological symptoms such as lethargy that may accompany neonatal jaundice. Medical staff or parents need to subjectively judge the infant's mental state, which can easily lead to delays in recognizing the worsening of the condition due to lack of experience or discontinuous observation. There are also some products on the market that focus on monitoring newborn sleep or vital signs, such as the infant sleep monitoring system of Shandong Deguang and other companies. Most of them rely on sound sensors or simple motion acceleration sensors for analysis. These devices lack direct monitoring of the pathological root cause, namely the level of jaundice. Their alarms are triggered only based on the infant's lack of activity or abnormal crying. They cannot distinguish between physiological deep sleep and pathological drowsiness, resulting in a high false alarm rate. Furthermore, they cannot provide early warning when the jaundice level rises but does not cause obvious behavioral changes.

[0004] Existing technologies include neonatal wristbands that attempt to integrate multiple physiological parameter monitoring functions, such as heart rate and blood oxygen sensors. However, these solutions are essentially simple aggregations of various functions and do not establish an intrinsic logical link between jaundice and sleep. They lack a linkage control mechanism that automatically triggers and enhances sleep depth analysis when bilirubin levels exceed a specific clinical threshold, thus failing to provide targeted and intelligent monitoring of neurological changes caused by jaundice. Existing transcutaneous detection devices mostly use a single, rigid probe that is fixed to the newborn's delicate skin for extended periods, easily causing local pressure, skin allergies, or probe displacement, affecting the continuity and accuracy of monitoring. Furthermore, existing devices lack convenient sterilization and centralized charging designs for the monitoring components themselves, which is not conducive to long-term hygienic use in a home environment.

[0005] In summary, traditional newborn smart bracelets have several drawbacks, including the lack of an inherent logical connection between jaundice and sleep, limited functionality, low continuity and accuracy of monitoring, and the potential to cause discomfort to newborns. Summary of the Invention

[0016] Compared with the prior art, the beneficial effects of the present invention are: This invention uses transcutaneous jaundice values ​​as trigger conditions, combined with the core logic of adaptive sleep depth analysis, changing the independent and fragmented state of jaundice and sleep monitoring in traditional devices. By preset clinically recognized bilirubin thresholds, it can automatically and without manual intervention initiate precise tracking of the key neurological symptom "drowsiness" when jaundice reaches a risk level, achieving early and objective warning of acute bilirubin encephalopathy and buying valuable time for medical intervention. This invention integrates optical jaundice monitoring probes into multiple independent, soft jaundice monitoring patches, replacing the traditional single rigid probe. This distributed design avoids the risk of neonatal skin damage due to prolonged local pressure, and multi-point measurement reduces measurement errors caused by displacement or poor contact of a single probe, thus improving data reliability. In this smart bracelet monitoring, once the bilirubin level exceeds the threshold, the system immediately switches to the precise analysis mode, increasing the sampling frequency and data analysis depth of sleep monitoring, realizing real-time tracking of drowsiness, ensuring monitoring accuracy during critical periods, while effectively optimizing the overall power consumption of the system and extending the device's battery life; The integrated UV disinfection LED in the bracelet storage box can disinfect the stored bracelets and monitoring patches, reducing the risk of infection.

It wirelessly charges the smart monitoring bracelets and jaundice monitoring patches through the built-in charging contact C, solving the cumbersome problem of charging multiple small devices separately. It is very suitable for long-term use in home settings. Attached Figure Description

[0022] See Figure 3 , Figure 4 and Figure 7 The smart monitoring bracelet 3 includes a case 31 and a strap assembly. The case 31 houses a flexible circuit board A312, a three-axis accelerometer 313, and a rechargeable battery A311. A charging contact A34 is fixedly mounted at one end of the case 31, and a speaker 35 is fixedly mounted at the other end. A cover 32 is fixedly mounted on the top of the case 31, and a touch display module 33 is fixedly mounted on the surface of the cover 32. A PPG optical heart rate sensor 314 is fixedly mounted on the bottom of the case 31. The strap assembly includes a wristband A36 and a wristband B38. The surface of the wristband A36 has multiple evenly distributed fixing holes 37, and the surface of the wristband B38... One end of 38 is fixedly provided with a binding strap 39, and a fixing buckle 310 is fixedly provided on the inner side of the binding strap 39. The fixing buckle 310 matches the fixing hole 37.

The charging contact A34 is electrically connected to the rechargeable battery A311. The rechargeable battery A311 is electrically connected to the MCU through the power management module. The triaxial accelerometer 313, the touch display module 33 and the PPG optical heart rate sensor 314 are all electrically connected to the MCU. The MCU is electrically connected to the wireless communication module, the storage module and the Bluetooth module. When in use, wear the smart monitoring bracelet 3 on the newborn's wrist and adjust the tightness using wristbands A36 and B38 to make the fixing buckle 310 fit into the fixing hole 37, ensuring that the PPG optical heart rate sensor 314 is in close contact with the skin. Apply the three jaundice monitoring patches 6 to the newborn's forehead, cheeks, or sternum. The low-sensitivity silicone layer 61 ensures a comfortable and non-irritating fit. Press and hold the touch display module 33 of the smart monitoring bracelet 3 to turn it on. The device will automatically enter Bluetooth pairing mode. After the jaundice monitoring patch 6 is powered on, it will send a broadcast signal. The bracelet's main control unit will complete the binding through the Bluetooth module and establish two-way communication.

[0023] The 313 triaxial accelerometer (taking the MMA8452Q as an example) has the following measurement ranges: ±2g / ±4g / ±8g (±2g is sufficient for newborn scenarios, providing higher sensitivity); Output data rate (ODR): 100Hz (balancing real-time performance and power consumption, data is collected every 10ms); Power consumption: operating current <200μA, standby current <1μA, suitable for the low power consumption requirements of fitness trackers; Package: 3mm×3mm×0.9mm LGA package, compact size, easy to integrate into the fitness tracker motherboard; PPG optical heart rate sensor (taking MAX30102 as an example): Light source: Integrated 660nm red light + 940nm (infrared light) dual LEDs, avoiding crosstalk with the 450nm / 550nm light source for jaundice detection; Detection accuracy: Heart rate measurement range 30-200 beats / min, error ±2 beats / min, adapted to the heart rate range of newborns; Power consumption: Heart rate monitoring mode current <1mA, standby current <0.1μA, supports intermittent working mode; Package: 5.6mm×2.8mm×1.45mm DFN package with optical shielding layer, resisting ambient light interference. See Figure 5 , Figure 6 and Figure 7 The jaundice monitoring patch 6 includes a medical patch and a packaging box 63. A jaundice optical monitoring probe 612 is fixedly installed at the bottom of the packaging box 63. A flexible circuit board B67 and a rechargeable battery B68 are fixedly installed on the inner wall of the packaging box 63. A rechargeable contact B69 is fixedly installed on one side of the packaging box 63. Card insertion holes 66 are fixedly provided at the four corners of the inner wall of the packaging box 63. Card insertion posts 65 are matched to the card insertion holes 66. A packaging cover 64 is fixedly provided between multiple card insertion posts 65. A retaining ring 610 is fixedly provided at the bottom of the packaging box 63. The medical patch includes an insulating patch 62 and a low-sensitivity silicone layer 61 fixedly disposed inside the insulating patch 62. A connecting hole 611 is opened in the middle of the insulating patch 62, and a fixing ring 610 is fixedly disposed inside the connecting hole 611. An MCU, a Bluetooth module and a power management module are fixedly mounted on the surface of the flexible circuit motherboard B67. A charging contact B69 is electrically connected to a rechargeable battery B68. The rechargeable battery B68 is electrically connected to the MCU through the power management module. The MCU is electrically connected to the jaundice optical monitoring probe 612 and the Bluetooth module. When in use, the jaundice monitoring patch 6 automatically activates the jaundice optical monitoring probe 612 every 30 minutes according to a preset cycle, emitting 450nm blue light and 550nm green light to collect the ADC value of skin reflected light. This data is then transmitted in real time to the smart monitoring bracelet 3 via Bluetooth. The bracelet's main control unit MCU calculates the transcutaneous bilirubin concentration based on the reflected light data and displays it on the touch display module 33. Simultaneously, the sleep monitoring module continues to run, with the three-axis accelerometer 313 collecting motion data and the PPG optical heart rate sensor 314 collecting heart rate data. The algorithm determines the newborn's sleep state (awake, light sleep, deep sleep) in real time. All data is stored in the storage module and synchronized to the parent's mobile APP via the wireless communication module.

[0024] In this embodiment of the application, the main control unit of the bracelet presets bilirubin thresholds: warning level (TCB: 12-15mg / dL), alarm level (TCB: 15-18mg / dL), and emergency level (TCB≥18mg / dL). The thresholds can be adjusted via the APP according to clinical recommendations. When the jaundice monitoring patch 6 detects TCB values ​​exceeding the warning level twice consecutively, the main control unit of the bracelet automatically activates the "precise analysis mode" of the sleep monitoring module, increases the sleep data sampling frequency from once every 10 minutes to real-time continuous sampling, and starts in-depth data analysis. Acceleration data: A sliding window filter was used with a window size of 1 second to filter out interference signals such as newborn breathing and slight vibrations. The "maximum acceleration difference" within every 10 seconds was extracted as the activity level feature value. Heart rate data: The peak value of the PPG signal was identified through a peak detection algorithm. The average heart rate and heart rate variability (HRV) within every 30 seconds were calculated, and abnormal noise (such as sudden increases or decreases in value exceeding 30 beats / minute) was removed. The sleep state judgment logic is shown in the table below: ; When the jaundice level is alarming (TCB: >15mg / dL) and the newborn is in a deep sleep: the main control unit calls the current sleep state data, determines it as "deep sleep", and executes the warning action: the touch display module 33 flashes red / yellow light at a low brightness, and at the same time pushes a reminder message to the APP through the wireless communication module: "Jaundice level is rising, the newborn is in a deep sleep, please pay close attention"; When the jaundice level is critical (TCB: >18mg / dL) and the newborn is in a light sleep state: the main control unit of the wristband determines "light sleep" and executes an upgraded warning: the touch display module 33 is constantly lit and flashes at high frequency, the speaker 35 emits a buzzer sound, and at the same time the wristband triggers high-frequency vibration through the three-axis accelerometer 313. The APP receives a strong push notification (including sound prompt): "Jaundice level is critical, please seek medical attention immediately!" The system automatically records the event time, jaundice trend and sleep data for medical personnel reference.

[0025] When the sleep monitoring module determines that the newborn has entered deep sleep, the main control unit of the wristband sends a command to the jaundice monitoring patch 6 to reduce the brightness of the optical probe light source and extend the detection interval, such as changing it from once every 10 minutes to once every 30 minutes, to reduce the interference of light stimulation on sleep. If the jaundice value drops back to the normal range, the system automatically resumes the regular monitoring mode and optimizes power consumption.

[0026] Three jaundice monitoring patches were applied to the newborn's forehead, cheek, and sternum for multi-point measurements. The wristband's main control unit integrated data from multiple patches to calculate the average TCB value, reducing errors caused by single probe displacement or poor contact. When a data point was abnormal (e.g., the difference from other points exceeded 2 mg / dL), the system automatically marked that data point as invalid and prioritized the use of data from other points to ensure monitoring continuity. The system has a built-in neonatal sleep database, referencing sleep cycle standards for different ages. When the TCB value exceeded 342 mol / L (20 mg / dL), combined with clinical research data (e.g., the negative correlation between TCB and sleep-wake cycles, r = -0.689), the system automatically assessed the risk of excessive sleepiness. The monitoring data stored in the wristband can be exported as reports to support medical diagnosis. For example, when the TCB value continues to rise and sleep data shows an abnormally high proportion of deep sleep, it suggests the risk of acute bilirubin encephalopathy.

[0027] After use, place the smart monitoring bracelet 3 and jaundice monitoring patch 6 back into the bracelet storage box 1, close the box lid 2, and turn on the ultraviolet disinfection lamp 9 for daily disinfection. The storage box has a built-in flame-retardant partition 13 to ensure battery and circuit safety and avoid overheating risks. In the normal monitoring mode, the system adopts a low-power strategy: the jaundice detection interval is adjustable from 10 to 60 minutes, and sleep monitoring uses periodic sampling. When the jaundice value is abnormal, it switches to high-performance mode to extend the overall battery life. The battery power of the bracelet and monitoring patch is displayed in real time through the touch display module 33 and the APP, and a charging reminder is given when the battery is low.

[0028] The "Guidelines for the Diagnosis and Treatment of Neonatal Hyperbilirubinemia (2025 Edition)" state that transcatheter bilirubin (TCB) is a very convenient non-invasive method for measuring bilirubin. Clinical evidence shows that routine TCB screening can effectively reduce the incidence of severe hyperbilirubinemia. When bilirubin levels are within a certain range, TCB and TSB have a good correlation. When TSB < 257 μmol / L (15 mg / dL), the difference between the two is < 51 μmol / L (3 mg / dL). Therefore, TCB can be used as a screening tool to effectively reduce the number of blood samples collected. However, when TCB ≥ 257 μmol / L... When the difference between TSB and phototherapy threshold is <51 μmol / L (3 mg / dl) or <51 μmol / L (3 mg / dl), the difference increases. Therefore, TSB needs to be measured to accurately assess the severity of hyperbilirubinemia [14, 15]. TSB of 342 to <427 μmol / L (20 to <25 mg / dl) is defined as severe hyperbilirubinemia, 427 to <510 μmol / L (25 to <30 mg / dl) is defined as very severe hyperbilirubinemia, and ≥510 μmol / L (30 mg / dl) is defined as dangerous hyperbilirubinemia.
