SMART WEARABLE WRISTBAND WITH ELECTRICAL ELECTRODES FOR NON-INVASIVE NEUROSTIMULATION AND NON-INVASIVE HIGH BLOOD PRESSURE RELIEF SYSTEM

The present invention relates to a smart wearable wristband with electrical electrodes for non-invasive neurostimulation, comprising: a main unit for fitting around a wrist and measuring user's vital signs; and a stimulation portion for stimulating median nerve or ulnar nerve located below Neiguan PC 6 or JianShi PC 5. According to the present invention, hypertension or stress can be effectively alleviated.

FIELD OF THE INVENTION

The present invention relates to a smart wearable wristband equipped with electrical electrodes for non-invasive neurostimulation. More specifically, it concerns a wristband designed to stimulate the wrist nerves with low-frequency electrical impulses, thereby aiding in user relaxation. This work was supported by the Korea Medical Device Development Fund grant funded by the Korea government (the Ministry of Science and ICT, the Ministry of Trade, Industry and Energy, the Ministry of Health & Welfare, the Ministry of Food and Drug Safety) (Project Number 1711196543, RS-2023-00253560).

BACKGROUND

With the recent proliferation of smartphones and wearable devices, there has been increased attention on health metric measurement. Traditionally, these applications have primarily involved using accelerometer sensors to measure steps and activity levels, or heart rate sensors for monitoring cardiac rates. However, there has been a growing interest in leveraging ECG sensors to monitor medically significant indicators, including arrhythmia, blood pressure, and blood glucose levels.

To facilitate real-time monitoring of these vital signs, wearable devices are designed to be worn on the wrist and portable. By integrating with medical technology, these devices can utilize the measured vital signs to monitor or diagnose a user's physical condition.

Recent medical journals have reported that changes in vital signs, such as heart rate, occur when individuals experience stress or excitement. It has been demonstrated that these conditions can be quantified and managed by using the vital sign data collected from wristbands.

Additionally, recent advances in traditional Chinese medicine suggest that non-invasive electrical stimulation can stabilize vital signs under stress. Moreover, numerous efforts are underway to treat various conditions, including hypertension, using non-invasive electrical stimulation methods. These approaches for stress relief and other treatments could offer significant benefits if integrated into wearable devices, allowing for continuous verification of their effectiveness through vital sign monitoring. However, the inadequate technological development in wearable devices has hindered their practical implementation.

Furthermore, although many smart wristbands on the market are capable of analyzing stress and excitement through vital sign measurements, none include a device for delivering electrical stimulation. This necessitates the use of separate modules, leading to the inconvenience of carrying multiple devices.

As shown inFIGS.1to3, a smart wearable wristband with electrical electrodes for non-invasive neurostimulation according to the present invention includes: a main unit100formed to fit closely to a wrist to measure a user's vital signs in real time for diagnosis; a stimulation band200attached on one side of the main unit100and electrically connected to the main unit100to receive power; and a securing band250attached on the other side of the main unit100and coupled to the stimulation band200to secure the main unit100and the stimulation band200; and a stimulation portion400formed to be positionable on the stimulation band200and powered by the stimulation band200to stimulate nerves in the wrist area.

The main unit100may include a sensor part on the lower surface to measure the user's vital signs, and the sensor part enables the user's biometric information, stress state, and excitement state to be grasped.

The main unit100may have a communication module for communicating with an external smart device, a battery for supplying power, and a control module for diagnosing a user's condition and prescribing electrical stimulation based on information acquired through the sensor part, and, if necessary, the upper surface of the main unit100is formed as a display so that the operating status can be checked.

In addition, a plurality of control buttons105are provided on the side of the main unit100to control or operate the operation of the main unit100, and a charging terminal or a wireless charging module is formed to supply external power to the battery.

It can be, but is not limited to, a rectangular shape, but can also be a circle or a square with rounded corners.

Furthermore, to ensure that the main unit100remains closely fitted to the wrist, stimulation band200and securing band250are attached to both sides of the main unit100. Each band wraps around opposite sides of the wrist and then overlaps and secures together, effectively holding the main unit100in place on the wrist.

The stimulation band200may have pogo pins211formed thereon for engagement with the connection terminal107formed on one side of the main unit100, and the pogo pins211are electrically connected to the main unit100by contacting the connection terminal107, thereby enabling the main unit100to receive power from a battery formed inside the main unit100.

Furthermore, the stimulation band200has a plurality of fastening holes232formed at regular intervals in the center from one end to the other end, and a loop-shaped fastening loop240is formed at the other end of the stimulation band200into which a securing band250can be inserted.

The fastening holes232are used to insert the fastening end260formed at the end of the securing band250to secure the securing band250to the top of the stimulation band200, and the fastening loop240is used to allow the securing band250to be inserted inwardly so that the securing band250does not swing from side to side once it is engaged in the fastening hole232.

The securing band250is attached on the other side of the main unit100and is used in conjunction with the stimulus band200to secure the main unit100closely to the wrist, and has a downwardly protruding fastening end260that can be inserted into the fastening hole232of the stimulation band200to keep the main unit100and the stimulation band200wrapped around the wrist.

In this case, the securing band250may be configured as the same as the stimulation band200, if necessary, with the fastening loop240changed to the fastening end260, in which case the stimulation portion400may also be positioned on the securing band250to provide electrical stimulation.

The stimulation portion400may be formed in the form of a ring that wraps around the outer surface of the stimulation band200so that it can be moved along the outer surface of the stimulation band200in one direction or the other, and the lower surface is formed to stimulate the nerve based on the power supplied from the stimulation band200, so that the nerve can be stimulated according to the state of the user to relieve muscle tension by stimulating the nerve with electricity according to the state of stress or excitement.

As described herein, the Neiguan PC 6 and the JianShi PC 5 are acupuncture points located on the inner side of the arm (where the inner side refers to the direction of the palm of the hand). The Neiguan PC 6 is located approximately three fingers' breadth from the wrist crease (seeFIG.12B), while the JianShi PC 5 is situated 3 cm towards the shoulder from the Neiguan PC 6. Moreover, ‘proximal’ in this context refers to points within a distance of 1 cm or less from either the Neiguan PC 6 or the JianShi PC 5.

Meanwhile, the stimulation portion400can electrically stimulate the median nerve1100or ulnar nerve1200located below the Neiguan PC 6 or the JianShi PC 5 by passing current. By targeting these nerves, this invention can effectively help in managing hypertension and alleviating stress.

Furthermore, the stimulation portion400is designed to accommodate the end of the securing band250inserted through the fastening loop240, thus preventing lateral movement of the securing band250. Details on how the stimulation portion400stimulates the wrist nerves will be discussed later with reference to the attachedFIG.6.

FIG.4is an assembly view showing the structure of a stimulation band200in a smart wearable wristband equipped with electrical electrodes for non-invasive neurostimulation, according to the present invention.FIG.5is a top view showing the structure of an FPCB210in a smart wearable wristband with electrical electrodes for non-invasive neurostimulation, according to the present invention.FIG.6is a bottom view showing the appearance of a stimulation portion400in a smart wearable wristband with electrical electrodes for non-invasive neurostimulation, according to the present invention.

As depicted inFIGS.4to6, the stimulation portion400includes a stimulation band200consisting of: a FPCB210equipped with pogo pins211at one end for connecting to the main unit100, and a pair of electrified holes212positioned at regular intervals to supply power across the FPCB210from one end to the other. Additionally, a fixture220is located at one end of the FPCB210to encase and protect the exterior of the pogo pins211and to prevent detachment when connected to the main unit100. There is also a housing230with an opening on one side to accommodate the FPCB210, featuring connection holes231aligned with the electrified holes212at regular intervals, allowing the electrified holes212to be exposed externally and connect to the stimulation site400shown inFIG.6.

The FPCB210is further characterized by the housing230, which is designed to bend or flex to fit the contour of the wrist. This flexibility allows the intensity and timing of the stimulation provided by the stimulation portion400to be adjusted based on the vital sign data collected by the main unit100.

The stimulation portion400features a body410designed with openings at the front and back, allowing it to encircle and slide along the outer surface of the stimulation band200. Additionally, a pair of electrode ends420are situated on either side of lower surface of the body410. One side of these electrodes connects electrically to supply positive and negative power when inserted into the stimulation band200, while the other side contacts the wrist to deliver electrical stimulation.

The stimulation band200is designed to connect to the battery in the main unit100shown inFIG.1for power and has an FPCB210, a fixture220, and a housing230. These components function to operate the stimulation portion400in response to control signals from the control module, facilitating nerve stimulation.

The FPCB210is a substrate crafted from flexible material, designed to easily conform to the user's wrist shape. It integrates various electronic components that regulate the operation of the electrical stimulus based on signals from the control module.

At one end of the FPCB210, multiple pogo pins211are installed to establish electrical connections with the connection terminals107on the main unit100. Each pogo pin211is connected to a power lines214and a control line215, both of which are integrated into the FPCB210.

In the case of the power lines214, the + and − electrode wires are separately formed to allow the stimulation portion400to apply electrical stimulation, and the control wire215can be used to control the intensity, stimulation time interval for electrical stimulation.

The FPCB210also has a plurality of through-holes213in the center from one end to the other, the through-holes213being formed to allow the fastening end260formed on the securing band250ofFIG.1to pass through and engage the FPCB210when inserted into the fastening holes232formed in the housing230.

Both sides of the through-hole213are provided with a plurality of electrified holes212to which the power lines214of the + electrode and the power lines214of the − electrode are connected, respectively, and the electrified holes212are formed by a pair of + and − electrodes spaced apart from each other with respect to the through-hole213.

In this case, the power lines214of the + electrode are connected to the through-hole213formed on one side of the through-hole213, and the power lines214of the − electrode are connected to the through-hole213formed on the other side of the through-hole213, so that the electrified holes212located on either side of the through-hole213can be fixed with either + or − poles.

Additionally, the FPCB210may be configured with a control circuit to receive a control signal from the main unit100through the control line215or to transmit the status of performing the electrical stimulation to the main unit100, and to change the intensity, intensity, pattern, and position of the electrical stimulation based on the biometric information of the user determined from the main unit100.

The fixture220is designed to encase the top of the pogo pins211formed on the FPCB210, protecting them from external impacts. It also locks into the housing230when the FPCB210is inserted, preventing the FPCB210from detaching. Additionally, when the main unit100is connected to the FPCB210, the fixture220ensures that the housing230remains securely attached to the main unit100.

In essence, the fixture220is designed to fasten the FPCB210within the housing230and to secure the housing230to the main unit100. The fastening mechanism can be a hook, snap fit, or screw connection.

The housing230features an opening on one side to allow the insertion of the FPCB210. It is preferably made from an elastic synthetic resin material such as silicone or rubber. This material choice not only insulates against the effects of the electrodes but also minimizes the risk of inducing skin diseases upon contact with the skin.

The FPCB210, which is inserted inside the housing230, is also made of a flexible material that allows the substrate to bend, and the housing230is also formed of a synthetic resin material, which allows it to conform to the user's wrist.

The housing230features a connection hole231and a fastening hole232, which align with the electrified holes212and the through hole213in the FPCB210, exposing them to the exterior. This alignment allows the electrode end420on the stimulation portion400to contact the electrified holes212through the connection hole231, enabling it to receive electricity.

The fastening holes232are designed to accommodate the fastening end260from the securing band250shown inFIG.1. This fastening end260sequentially passes through the fastening holes232on the upper surface of the housing230, the through-hole213in the FPCB210, and the fastening holes232on the lower surface of the housing230, where it then engages to secure the securing band250to the stimulation portion200.

The other side of the housing230is also provided with a fastening loop240formed in the form of a ring into which the securing band250can be inserted, the fastening loop240being used to secure the left and right position of the securing band250when the fastening end260of the securing band250is inserted into the fastening hole232.

The stimulation portion400contacts the skin on the user's wrist and administers low-frequency electrical stimulation to promote relaxation, reducing stress and excitability. Comprising a body410and an electrode end420, the stimulation portion400also helps alleviate hypertension by electrically stimulating the median and ulnar nerves located beneath the Neiguan (PC6) and JianShi (PC5) acupoints.

The body410is made from a silicone ring that allows it to move along the outer surface of the housing230while insulating against electrical conduction. The electrode ends420are constructed as two separate components on the lower surface of the body410.

Here, the two electrode ends420are formed to receive power by contacting the + and − poles of the electrified holes212formed on the FPCB210, respectively, and based on the power received, the user's wrist can be electrically stimulated.

To facilitate the insertion of the electrode ends420through the connection holes231in the housing230to the electrified holes212on the FPCB210, the electrode ends420are designed with one end elongated towards the interior of the body410. The other end is shaped in a flattened form to prevent a foreign sensation when contacting the user's wrist.

The other end of the electrode ends420that contact the user's wrist is preferably protruding higher than the surface of the body410because if it is aligned with the lower surface of the body410, the electrode ends420may not make contact with the skin of the wrist and no electrical stimulation may be applied.

When the electrode ends420are connected to the electrified holes212, the electrode end420formed on one side are connected to the power line214of the + electrode, and the electrode end420formed on the other side is connected to the power line214of the electrode.

This configuration ensures that the two electrode ends420, each connected to different electrodes on opposite sides, contact the user's wrist when energized. An electrical stimulus is then applied as current flows between these two electrode ends420.

FIG.7is a bottom perspective view illustrating a stimulation portion400of a smart wearable wristband with electrical electrodes for non-invasive neurostimulation coupled to a stimulation band200in accordance with the present invention.

As shown inFIG.7, a stimulation portion400of a smart wearable wristband with electrical electrodes for non-invasive neurostimulation according to the present invention is characterized in that the stimulation portion400is formed to slide along the stimulation band200so that the neurostimulation portion can be adjusted.

The stimulation portion400is also characterized in that it is formed in a plurality to allow simultaneous stimulation at various locations on the wrist.

Because the stimulation portion400is ring-shaped, it can be freely moved along the outer surface of the stimulation band200, allowing the stimulation portion400to be moved to the point or nerve location that needs to be stimulated and then electrically stimulated.

Since the stimulation portion400must be in communication with the stimulation band200to be powered, its range of movement is limited to the location of the connection hole231formed in the stimulation band200, but there are substantially multiple electrified holes212from one end of the stimulation band200to the other end, so it can be moved to various locations to apply electrical stimulation.

The stimulation portion400can also be formed into multiple stimulation bands200to simultaneously apply electrical stimulation to various parts of the body according to the user's biometric information, thereby realizing the same effect as acupuncture points on various parts of the body from a Chinese medicine perspective.

When multiple stimulation portions400are formed, the FPCB210inside the stimulation band200may be formed to individually control the power supplied to each electrified hole212, and such control may allow multiple stimulation portions400to be sequentially electrically stimulated according to symptoms.

Moreover, since the insertion points of the electrode ends420are determined by the electrified holes212, the main unit100can also provide location information to the user. This enables targeting specific points for neurostimulation based on the biometric information gathered.

As discussed, a smart wearable wristband featuring an electrical electrode for non-invasive neurostimulation, as per this invention, can alleviate symptoms or conditions by applying electrical stimulation based on stress levels and excitability measured through biosignal monitoring. The device allows for the modification and adjustment of the electrical stimulation applied to the wrist. This enables the stimulation of various acupuncture points from the perspective of Chinese medicine. Additionally, its portability and integrated electrical stimulation module allow for easy application of stimulation outdoors, thereby helping to stabilize the user's vital signs.

Referring now toFIGS.8through11, a detailed description follows of a non-invasive hypertension and stress relief system according to another embodiment of this invention.FIG.8provides a conceptual diagram of this system, illustrating one embodiment of the present invention.

Referring toFIG.8, a non-invasive hypertension relief system according to another embodiment of the present invention includes a user terminal500, a hypertension and stress reliever440, and an AI analysis server600.

The user terminal500transmits the user's physical information to the AI analysis server600.

More specifically, the user terminal500communicates wirelessly (LTE/Wi-Fi/BLE, etc.) with the main unit100of wearable device to receive physical information transmitted from the wearable device.

Here, the physical information may include biometric information (vital signs) and activity information about the user. Specifically, the biometric information may include at least one of blood pressure, oxygen saturation, respiration, pulse, body temperature, and blood glucose. Further, the activity information includes at least one of falls, sleep, steps, activity time, GPS location information, and three-dimensional inertial location information.

FIG.9is a block diagram illustrating a non-invasive hypertension relief system according to one embodiment of the present invention.

In this embodiment, the user terminal500may be a smartphone, but is not limited thereto, and may be any wirelessly communicable electronic device, such as a tablet PC, MP3 player, or the like.

As shown inFIG.9, the user terminal500includes a smartphone power unit510, a smartphone communication unit520, an input unit530, an adjustment unit540, and a meditation audio unit550.

The smartphone power unit510provides power to the power connector480when electrically coupled to the power connector480. The power connector480may also receive power from the main unit100of wearable device.

The smartphone communication unit520maintains wireless communication (LTE/Wi-Fi/BLE, etc.) with the main unit100, the hypertension and stress reliever440, and the AI analysis server600, and is specifically designed to transmit and receive information. Additionally, this unit is electrically connected to both the input unit530and the adjustment unit540, and it forwards physical data from the wearable device to the AI analysis server600.

Further, the smartphone communication unit520may receive Stimulation information transmitted from the AI analysis server600. The stimulation information may include at least one of a stimulation waveform, a operation mode, a stimulation time, a vibration mode, a near-infrared irradiation mode, and a far-infrared irradiation mode.

Specifically, the stimulation waveforms can include: an R-wave (square wave) based at 13 Hz, ranging from 10 Hz to 100 Hz, known for its strong energy intensity and its vibratory stimulation effect on acupuncture points; a P-wave (triangle wave) based at 3 Hz, ranging from 3 Hz to 20 Hz, which has a lower energy intensity but a potent stimulation effect on acupuncture points; and an S-wave (sine wave) based at 20 Hz, ranging from 5 Hz to 100 Hz, which provides gentle stimulation and massages the areas around acupuncture points.

Additionally, the intensity of all stimulus waveforms can be adjusted in 10 steps, ranging from 2 mA to 13 mA, based on a human body resistance of 500Ω. Furthermore, the default intensity settings for each stimulus waveform are 1× for the P-wave, 2× for the R-wave, and 3× for the S-wave.

There are three modes of operation: sequential mode, which applies the stimulus waveform to the electrodes in rotation, fixed mode, which fixes the stimulus waveform for each electrode, and single mode, which applies the same stimulus waveform to all electrodes.

Specifically, sequential mode applies different stimulus waveforms to multiple electrode pairs and alters the stimulus waveform at time intervals shorter than the period of the lowest frequency among the multiple stimulus waveforms.

In addition, the fixed mode applies different stimulus waveforms to multiple electrode pairs and the stimulus waveform does not change while the multiple electrode pairs are activated.

On the other hand, the single mode applies the same stimulus waveform to multiple electrode pairs.

If the control unit540automatically controls the Stimulation information, the smartphone communication unit520transmits the Stimulation information to the hypertension and stress reliever440.

The input unit530enables manual input of physical information by the user, and enables inquiry of body analysis information, blood pressure history information, and stimulation information.

Specifically, the input unit530can manually input physical information through the user's operation and retrieve physical information managed by the AI analysis server600and stimulation information analyzed by the AI analysis server600.

Accordingly, the input unit530is electrically connected to the smartphone communication unit520.

The adjustment unit540automatically or manually controls the Stimulation information transmitted from the smartphone communication unit520and transmits it to a smartphone receiving unit provided in the smartphone communication unit520.

First, when the adjustment unit540automatically controls the Stimulation information, the adjustment unit540transmits the automatically controlled Stimulation information to the smartphone communication unit520.

On the other hand, when the adjustment unit540manually controls the Stimulation information, the adjustment unit540adjusts the Stimulation information transmitted from the AI analysis server600and transmits the adjusted Stimulation information to the hypertension and stress reliever440while simultaneously operating the meditation audio unit250. The adjustment unit540is electrically connected to the smartphone communication unit520and the meditation audio unit550. The meditation audio unit550generates one of meditation music, meditation sounds, and white noise.

The hypertension and stress reliever440, worn on at least part of the user's body, delivers one or more types of stimulation-electrical, vibrational, or light-to at least part of the user's body. This is in response to stimulation information received from the AI analysis server600.

Here, photostimulation includes light irradiation using far infrared light and light irradiation using near infrared light.

For this purpose, the hypertension and stress reliever440may communicate wirelessly (LTE/Wi-Fi/BLE, etc.) with user terminal500or main unit100of the wearable device to the AI analysis server600.

Additionally, a hole is formed in the center of the hypertension and stress reliever440for passing near-infrared light from the near-infrared LED446, as shown inFIG.10B.
