Abstract
Description
Technical Field
[0001] This invention relates to the field of vital sign monitoring equipment technology, and in particular to a miniature wearable vital sign monitoring device. Background Technology
[0002] Current vital sign monitoring technologies exhibit a significant application gap. In professional medical settings, traditional devices (such as electrocardiogram monitors, desktop pulse oximeters, and electronic thermometers) generally employ wired connections and fixed contact measurement methods. Their initial design purpose was to provide high-precision, short-cycle "snapshot" data for clinical diagnosis. These devices are typically bulky, require specialized operation, and are dependent on specific medical settings (such as wards and clinics). Users can only perform passive, on-demand, and fragmented measurements when they are unwell or during routine checkups, failing to reflect real-world physiological dynamic changes such as daily activities and sleep patterns.
[0003] With the popularization of wearable technology, consumer devices (such as smart bracelets and sports watches) have achieved mobile and seamless monitoring. However, existing mainstream wearable products still have significant limitations in functionality: most devices focus only on monitoring a single or a few vital signs (such as heart rate only, or heart rate + blood oxygen), and their measurement modes are often intermittent and triggered sampling (such as users actively initiating measurements or continuously monitoring heart rate only during exercise). This "fragmented and selective" monitoring method essentially transfers the logic of traditional "on-demand testing" to portable devices, and does not truly achieve continuous and synchronous monitoring of all vital signs at all times.
[0004] This technological gap leads to two core problems: First, the data dimensions are incomplete: a single parameter (such as heart rate) lacks cross-validation with multi-dimensional data such as respiration, blood oxygen, and body temperature, making it difficult to support a comprehensive health status assessment (for example, it is impossible to distinguish between an increase in heart rate after exercise and heart rate abnormalities caused by disease).
[0005] Second, lack of continuity: intermittent sampling may miss important physiological events (such as nocturnal apnea and paroxysmal arrhythmias), making the device only able to provide "health trend references" and unable to perform the truly continuous monitoring tasks required for early warning and chronic disease management.
[0006] Therefore, the current market urgently needs a new type of device that can break through the limitations of traditional wired on-demand models and the single functionality of existing wearable devices, achieving medical-grade multi-parameter, highly continuous, and low-load synchronous monitoring capabilities in a consumer-grade form, in order to fill the key technological gap between "passive diagnosis" and "proactive health management".

[0024] Reference Figures 1-4 This invention provides a miniature wearable vital sign monitoring device, comprising: The housing 1 includes an end cap 11 and a base 12. The end cap 11 is detachably connected to the top of the base 12, and a mounting cavity is formed between the end cap 11 and the base 12. Power supply system 2 includes charging coil 21, rechargeable battery 22 and power management circuit. Charging coil 21 is fixed on the top surface of rechargeable battery 22 and rechargeable battery 22 is installed in the upper part of the mounting cavity.

The sensing system 4 includes a heart rate and blood oxygenation chip 41, a temperature chip 42, a motion chip 33, an acceleration chip 34, and a positioning chip 35.

The heart rate and blood oxygenation chip measures heart rate and blood oxygenation parameters by reflection, while the temperature chip 42 directly contacts the skin to measure the body surface temperature. Adhesion module 5 is fixed at the bottom of connector 13; The microprocessor unit 32 integrates an edge computing module, a communication module, and an early warning module.
[0025] Through the cooperation of the adhesion module 5 and the connecting fixation device 13, it is stably attached to the surface of human skin (such as the chest area). The mounting cavity formed by the detachable connection of the end cap 11 and the base 12 provides safe protection for the internal components. In the power supply system 2, the rechargeable battery 22 is installed in the upper part of the mounting cavity to continuously power the entire device, and the charging coil 21 on the top surface has a reserved convenient charging channel to ensure the long-term use of the device. After the sensing system 4 is started, the heart rate and blood oxygen chip 41, located inside the connecting fixation device 13 and integrated on the bottom surface of the electronic circuit board 31, accurately collects heart rate and blood oxygen parameters through the reflective principle, and the temperature chip 42 directly contacts the skin to obtain real-time body surface temperature; at the same time, the motion chip 33 on the top surface of the electronic circuit board 31 monitors the wearer's movement status, the acceleration chip 34 calculates the breathing status, and the positioning chip 35 provides position assistance information.

[0026] Further optimization of the design: the outer shell 1 has a disc-shaped, cuboid, ellipsoidal, or cylindrical structure; the end cap 11 and the base 12 are both made by 3D printing or precision machining center, and the materials are Teflon, PEEK, or hard aluminum.
[0027] The scheme is further optimized so that the heart rate and blood oxygenation chip is one of the following: hydrocolloid electrode, long-term adhesive wet electrode, disposable wet electrode, integrated dry electrode, flexible dry electrode, textile electrode, or gold cup wet electrode.

While ensuring structural strength and lightweight, they provide reliable protection for internal components. The adhesion module 5 is coaxially fixed to the connector 13 through the cover-shaped adhesion seat 51. The bottom adhesive fixation of the ECG electrode 52 and the side ECG electrode 53 fits tightly against the skin.

At the same time, seven different types of ECG electrodes, such as hydrocolloid electrodes, are available to suit different needs such as long-term wear, short-term monitoring, and sports scenarios.
[0034] Power supply guarantee mechanism: The power supply system 2 uses lithium-ion or lithium polymer batteries as the energy core, and is equipped with magnetic wired connection or wireless charging coil (placed on the top surface of the battery). With the cooperation of thin end cover 11, the charging efficiency is improved. It not only supports convenient charging, but also avoids overcharging and over-discharging through charge and discharge protection circuit, providing stable energy support for the long-term continuous operation of the equipment.
[0035] The sensing system 4 integrates multiple sensors via a double-sided mounted electronic circuit board 31. The heart rate and blood oxygen chip 41 on the bottom collects heart rate and blood oxygen parameters using a reflective principle, while the temperature chip 42 directly attaches to the skin to obtain body surface temperature. The motion chip 33 on the top monitors the wearer's movement in real time and triggers warnings for dangerous events such as falls. The accelerometer chip 34 calculates breathing by sensing chest rise and fall, and the positioning chip 35 provides positional assistance information. All sensors are installed in the same cavity for in-situ synchronous acquisition, avoiding signal misalignment in time and space.
[0036] The collected multi-dimensional physiological signals are transmitted to the microprocessor unit 32, whose integrated edge computing module quickly completes data fusion and feature extraction to achieve real-time health status analysis; the communication module can select Bluetooth, radio or fiber optic communication according to the usage scenario to flexibly complete the remote transmission of data to the host computer; when abnormal heart rate, low blood oxygen, fall or other risks are detected, the early warning module immediately issues a local alarm, forming a closed loop of "collection-analysis-early warning".
