Description

Technical Field

[0001] The present invention relates to the technical field of dynamic monitoring equipment, and in particular to a wearable physiological signal monitoring finger cuff. Background Art

[0002] Physiological signal monitoring devices measure physiological parameters such as heart rate, electrocardiogram (ECG), pulse, and blood oxygen saturation, and compare these values ​​with the normal fluctuation range of physiological signals. If the measured values ​​are outside the normal range, an alarm will be issued. With the development of modern technology, physiological signal monitoring devices have become simpler and more portable, allowing people to observe changes in their bodies at any time.

[0003] Currently, most physiological signal detection devices on the market fall into two categories: smart bracelets that collect physiological signals at the wrist, and finger clips that collect physiological signals at the fingers. Smart bracelets collect physiological signals at the wrist, making them easy to carry. However, the light source does not make firm contact with the skin, and the wrist has fewer and deeper blood vessels, so the measurement results are affected by various external factors. Hairy arms, darker skin, or arm shaking can all lead to measurement errors. Physiological signal collection finger clips collect physiological signals at the fingers, where blood vessels are more numerous and shallower, resulting in more accurate measurements. However, due to their large size, using them to measure physiological parameters can interfere with normal life and work, making real-time monitoring of physiological signals inconvenient.

[0004] Based on this, the present invention designs a wearable physiological signal monitoring finger cuff to solve the above problems. Summary of the Invention

[0005] The purpose of the present invention is to provide a wearable physiological signal monitoring finger cuff to solve the problems raised in the above background technology.

[0006] To achieve the above-mentioned objectives, the present invention provides the following technical solutions: a wearable physiological signal monitoring cuff, comprising a monitoring cuff, a display bracelet, and an electrode sheet; a light shielding layer is provided in the monitoring cuff to prevent the light and light path for collecting physiological signals from being contaminated, thereby improving the accuracy of physiological signal detection; a sensor module is provided in the monitoring cuff, the sensor module comprises a first main controller, a light source driving front end, a light source transceiver, an ECG monitoring module, and a common-mode power supply; the first main controller is connected to the display bracelet for data transmission; the first main controller controls the light source driving front end to convert the collected signal into specific physiological signal data through an algorithm; the first main controller controls the ECG monitoring module for monitoring ECG waveforms; the light source driving front end is used to drive the light source transceiver to emit collected light; the light source transceiver is used to send and receive collected light; the common-mode power supply is used to power the first main controller, the light source driving front end, the light source transceiver, and the ECG monitoring module; the display bracelet comprises a second main controller, a positioning module, a communication module, a display module, and a right leg drive interface.

[0007] Furthermore, the monitoring finger sleeve and the display bracelet are connected via a connecting wire, and the display bracelet and the electrode sheet are connected via an electrode wire. Both the connecting wire and the electrode wire are used to transmit data.

[0008] Furthermore, the second main controller is used to receive and process data collected by the electrode sheet, the second main controller controls the positioning module to obtain position information to realize real-time tracking and positioning, the second main controller controls the communication module to send the collected information to the remote server for long-term recording, the second main controller controls the display module to display the collected physiological signals and other data, and the right leg drive interface is connected to the electrode sheet through the electrode line for high-precision ECG and blood pressure signal measurement.

[0009] Furthermore, the diameters of the connecting wires and the electrode wires are both less than 2 mm.

[0010] Furthermore, the monitoring finger cuff is made of fiber material, which allows the built-in sensor module in the finger cuff to fit closely to the skin, thereby ensuring the accuracy of physiological signal collection without affecting normal life and work.

[0011] Compared with the prior art, the present invention has the following beneficial effects:

[0012] 1. Compared to smart bracelets, this invention improves the measurement method. Using a fingertip, the sensor module is attached to the finger, ensuring close contact between the light source and the skin during exercise, ensuring data stability during measurement. The measurement position is improved. Measuring physiological signals at the wrist is difficult and easily affected by skin color and hair. This invention measures at the fingertips, where blood vessels are widely distributed and hairless, making it easier and more accurate to measure physiological signals.

[0013] 2. Compared with the physiological signal collection finger clip, the present invention improves the measuring equipment. The finger clip is small in size and can be used at any time to measure in real time. Wearing it does not affect the normal use of the finger and normal life and work.

[0014] 3. Compared with existing physiological signal measurement equipment, the present invention improves the data transmission and reception method, integrates the communication module and the positioning module, can remotely record long-term, track and locate in real time, and change the traditional mobile phone display and Bluetooth data transmission and reception method.

[0021] The following will clearly and completely describe the technical solutions in the embodiments of the present invention in conjunction with the accompanying drawings. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making any creative efforts shall fall within the scope of protection of the present invention.

[0022] See also Figure 1-3The present invention provides a technical solution: a wearable physiological signal monitoring finger cuff, including a monitoring finger cuff 1, a display bracelet 2, and an electrode sheet 3. A light shielding layer is provided in the monitoring finger cuff 1 to prevent the light and light path for collecting physiological signals from being contaminated, thereby improving the accuracy of physiological signal detection. A sensor module 4 is provided in the monitoring finger cuff 1. The built-in sensor module 4 is no larger than 10mm×10mm in size and collects pulse, finger temperature and blood pressure saturation. When used in conjunction with the electrode sheet, it can measure electrocardiogram, heart rate and blood pressure; the sensor module 4 includes a first main controller 401, a light source driving front end 402, a light source transceiver 403, an electrocardiogram monitoring module 404 and a common mode power supply 405. The first main controller 401 is connected to the display bracelet 2 for data transmission. The first main controller 401 controls the light source driving front end 402 to collect the collected signals. The signal is converted into specific physiological signal data through an algorithm. The first main controller 401 controls the ECG monitoring module 404 for monitoring the ECG waveform. The light source driving front end 402 is used to drive the light source transceiver 403 to emit collection light. The light source transceiver 403 is used to send and receive collection light. The common mode power supply 405 is used to power the first main controller 401, the light source driving front end 402, the light source transceiver 403 and the ECG monitoring module 404. The display bracelet 2 is 30mm×50mm×10mm in size. The display bracelet 2 includes a second main controller 201, a positioning module 202, a communication module 203, a display module 204 and a right leg driving interface 205. The electrode sheet 3 is attached to the right calf of the human body and connected to the display bracelet for high-precision ECG and blood pressure signal measurement. The second main controller 201 is connected to a buzzer.

[0023] The monitoring cuff 1 and the display bracelet 2 are connected via a connecting line 5 , and the display bracelet 2 and the electrode sheet 3 are connected via an electrode line 6 . Both the connecting line 5 and the electrode line 6 are used to transmit data.

[0024] The second main controller 201 is used to receive and process the data collected by the electrode sheet 3. The second main controller 201 controls the positioning module 202 to obtain position information to realize real-time tracking and positioning. The second main controller 201 controls the communication module 203 to send the collected information to the remote server for long-term recording. The second main controller 201 controls the display module 204 to display the collected physiological signals and other data. The right leg drive interface 205 is connected to the electrode sheet 3 through the electrode line 6 for high-precision ECG and blood pressure signal measurement.

[0025] The diameters of the connecting wire 5 and the electrode wire 6 are both less than 2 mm.

[0026] The monitoring finger cuff 1 is made of fiber material, which is elastic and does not squeeze the hand. The built-in sensor module 4 of the finger cuff can be closely attached to the skin to ensure the accuracy of physiological signal collection without affecting normal life and work.

[0027] A specific application of this embodiment is as follows: When using the present invention, the display bracelet 2 is worn on the wrist, the monitoring cuff 1 is worn on the thumb, and the position of the monitoring cuff 1 is adjusted so that the built-in sensor module 4 is close to the thumb pad. After wearing, long press the function button on the display bracelet 2 until the LCD screen lights up to realize the power-on function. After powering on, the screen rotates to display the collected pulse, finger temperature and blood oxygen saturation. If a physiological signal data is lower than the normal fluctuation range, the screen flashes to display the physiological signal value, and the buzzer emits a "beep" sound to achieve a prompt effect. After pressing the thumb of the other hand on the sensor module 4, the monitoring cuff 1 starts to collect electrocardiogram, heart rate and blood pressure signals, and the screen displays the electrocardiogram, heart rate value and blood pressure value. At the same time, the present invention has 4G and satellite positioning functions, and can upload the collected data to the cloud server. When the monitored physiological data is abnormal, it can remotely alarm and display the user's current location.

[0028] like Figure 1 As shown, point A is the emitted red light, point B is the reflected red light, and point C is the capillary. The light source transceiver 403 emits light of different wavelengths to illuminate the skin, and detects the intensity of the reflected light to obtain different physiological signal data.

[0029] Measuring pulse: Due to heartbeats, the blood volume in the blood vessels will change rhythmically. Part of the light emitted by the light source transceiver 403 will be absorbed by the blood in the blood vessels. The larger the blood volume, the more light is absorbed and the less light is reflected back. With the rhythm of the heartbeat, the blood volume in the blood vessels changes periodically, and the detected reflected light intensity also changes accordingly. The heart rate and pulse data can be calculated based on the interval of the detected light intensity signal change. If the incident light is green light, the reflected light caused by the heartbeat changes greatly, so the light source transceiver emits green light to monitor the pulse signal.

[0030] Measuring finger temperature: The built-in sensor module integrates a temperature sensor to monitor finger skin temperature and provide frostbite warning.

[0031] Measuring blood oxygen saturation: Blood oxygen saturation is the percentage of the capacity of oxygenated hemoglobin bound to oxygen in the blood to the total capacity of hemoglobin that can be bound. Oxygen, hemoglobin and deoxyhemoglobin can selectively absorb red light with a wavelength of 660nm and infrared light at 940nm. By detecting the intensity of the reflected red light and infrared light, the concentration ratio of oxygen, hemoglobin and deoxyhemoglobin can be obtained through algorithm processing, thereby obtaining the human body's blood oxygen saturation.

[0032] Because the heart generates electrical excitation before mechanical contraction, the current of myocardial excitation can be conducted from the heart through body tissue to the body surface, causing different potential changes in different parts of the body surface. The sensor module 4 built into the finger cuff integrates the ECG detection module 404, which detects the potential of the left and right hands and then processes the algorithm to obtain the ECG waveform. There are two monitoring positions to choose from:

[0033] ① Monitor the electrical potential at the pads of the thumbs of both hands. After wearing the finger sleeves, press the thumb of the other hand on the sensor module 4. In this method, the right leg drive signal is simulated by the first main controller 401;

[0034] ② Monitor the electrical potential at the pads of both thumbs and the right calf. Place electrode sheet 3 on the right calf and connect it to display bracelet 2 with electrode cable 6. Wear the fingertip and press the thumb of the other hand against sensor module 4. Display bracelet 2 transmits the electrical potential signal from the right calf to the first main controller 401 within sensor module 4. First main controller 401 analyzes the collected electrical potential signals from both thumbs and the received electrical potential signal from the right calf to obtain an ECG waveform. Both methods can measure the ECG waveform and thus obtain the heart rate signal, but the ECG waveform measured by method 2 is more accurate and can be used to calculate blood pressure.
