Description

Technical Field

[0001] This invention belongs to the field of wearable smart medical device technology, and in particular relates to an anti-rotation medical wristband with integrated electrocardiogram monitoring function. Background Technology

[0002] Cardiovascular disease is a leading cause of death worldwide, and electrocardiogram (ECG) monitoring is a core tool for its prevention, diagnosis, and prognostic assessment. With the increasing adoption of wearable devices in specialized medical fields, the clinical demand for high-precision, 24 / 7, and low-interference monitoring equipment is becoming increasingly urgent. Currently, traditional ECG monitoring equipment used in clinical practice faces several technical bottlenecks: a. Conventional "box-style" dynamic monitoring devices are bulky and heavy, resulting in poor patient comfort and limited mobility. The lead wires are also prone to tangling and falling off, making it difficult to meet the needs of long-term continuous monitoring. b. In terms of material application and structural design, the sensing components of existing wearable medical devices mostly use rigid materials or ordinary textile materials, which either have poor fit and insufficient comfort, or have insufficient mechanical strength. They cannot dynamically adapt to the wearing needs of patients in different activity states, and have insufficient fit stability. When patients turn over or become agitated, they are prone to rotation and displacement, which leads to serious motion interference in the acquisition of electrocardiogram signals. The signal-to-noise ratio is generally lower than the core requirement of 75dB for clinical diagnostic grade, which affects the accuracy of diagnosis. c. In terms of multi-parameter collaborative monitoring, existing devices generally have the limitation of single function, making it difficult to simultaneously acquire ECG signals and key biochemical indicators such as blood glucose and troponin I, and thus unable to provide comprehensive physiological status assessment for clinical use. At the same time, the power supply and data transmission of traditional monitoring devices rely on wired connections or short-range Bluetooth, resulting in problems such as insufficient battery life and low transmission rate (mostly below 256Kbps). d. In clinical practice, most biochemical testing chips are reusable, and the cleaning and maintenance process is cumbersome and poses a risk of cross-infection. Furthermore, there is a lack of seamless switching capabilities between in-hospital and out-of-hospital monitoring scenarios. The health data of discharged patients is difficult to effectively connect with the hospital's chronic disease management platform, which restricts the realization of continuous health management. In addition, there is a lack of linkage design for emergency scenarios. When emergencies such as cardiac arrest occur, it is difficult to quickly synchronize key information such as patient identity and medical history and link emergency equipment, which affects the efficiency of rescue. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide an anti-rotation medical wristband with integrated electrocardiogram monitoring function to overcome the shortcomings of the prior art.

[0004] To achieve the above objectives, the present invention is implemented through the following technical solution: A medical wristband with integrated electrocardiogram (ECG) monitoring function and anti-rotation function is provided. It includes a wristband body and a functional box that can form a closed loop connection. The wristband body is woven from an SMPU matrix and shape memory alloy wires. The inner ring of the wristband body facing the human body integrates a coplanarly arranged electrode array and a micro-electromyography (EMG) sensor array. The electrode array collects ECG signals in real time, and the micro-EMG sensor array collects wrist muscle tension signals in real time. The functional box integrates an intelligent main control module, a wireless energy data transmission module, and a parameter detection module. The intelligent main control module is pre-trained with a clinical diagnostic model. The clinical diagnostic model integrates ECG, EMG, and biochemical indicator data in real time, automatically identifies abnormal states such as arrhythmia, myocardial ischemia, and hyperlactatemia, and performs graded early warning pushes.

[0005] Furthermore, the wireless energy data transmission module in the anti-rotation medical wristband with integrated ECG monitoring function is a magnetic resonant coupling module that integrates magnetic resonant wireless power supply and data transmission functions.

[0006] Furthermore, the wireless energy data transmission module in the anti-rotation medical wristband with integrated electrocardiogram monitoring function also includes a 5G communicator and a wireless WiFi communicator.

[0007] Furthermore, when the anti-rotation medical wristband with integrated electrocardiogram monitoring function detects cardiac arrest, the function box sends location and patient data to the nearby defibrillator base station through the intelligent main control module and 5G communicator, drives the defibrillator to automatically turn on and plans the optimal access path, and at the same time sends emergency instructions containing the patient's identity, allergy history and past medical history to medical staff.

[0008] Furthermore, the functional box in the anti-rotation medical wristband with integrated ECG monitoring function switches to home health management mode after the patient is discharged through the intelligent main control module and wireless WiFi communicator, automatically connects to the home smart medical terminal, adjusts the monitoring frequency and early warning threshold, and synchronizes the data to the hospital's chronic disease management platform.

[0009] Furthermore, the parameter detection module in the anti-rotation medical wristband with integrated ECG monitoring function uses a magnetically plug-and-play disposable microfluidic chip in conjunction with a miniature optical detector to adapt to the quantitative detection of blood glucose, lactate, and troponin I.

[0010] Furthermore, the disposable microfluidic chip in the anti-rotation medical wristband with integrated ECG monitoring function has a built-in RFID traceability tag, which automatically records the detection time, chip batch number and detection results.

[0011] Furthermore, the alarm tiered push notification in the anti-rotation medical wristband with integrated ECG monitoring function includes: mild abnormalities are pushed to the responsible nurse's mobile terminal, and severe abnormalities trigger ward sound and light alarms, monitor emergency pop-ups, and doctor workstation alarms.

[0012] The beneficial effects of the technical solution of this invention are: It integrates ECG monitoring, anti-rotation, multi-module collaboration, and is adaptable to all scenarios inside and outside the hospital. It also incorporates cutting-edge technologies such as bio-intelligent detection and wireless energy data transmission to build an intelligent closed loop of "perception-decision-execution" that integrates multi-signal fusion diagnosis and early warning, emergency rescue linkage, and full-cycle management inside and outside the hospital, greatly improving the efficiency and accuracy of medical services.

[0015] The terms “invention” and “the present invention” used in this specification are intended to broadly refer to all subject matter of this specification and any of the following patent claims. Statements containing these terms should not be construed as limiting the subject matter described herein or limiting the meaning or scope of any of the following patent claims. Furthermore, this specification does not attempt to describe or limit the subject matter covered by any claim of any particular component, paragraph, statement, or drawing of this application. The subject matter should be understood with reference to the entire specification, all drawings, and any of the following claims. The invention may have other embodiments and be practiced or implemented in other ways. Moreover, it should be understood that the wording and terminology used herein are for illustrative purposes and should not be considered limiting.

[0016] The details of the invention will now be discussed with reference to the accompanying drawings, which are illustrated by way of example only. In the drawings, similar features or components may be labeled using the same reference numerals.

[0017] The use of the terms "comprising," "having," and "including," and variations thereof, herein means to include the items listed herein and their equivalents and additional items. While reference may be made in the description of the drawings to directions such as above, below, upward, downward, backward, bottom, top, front, rear, etc., for convenience, reference is made relative to the drawings. These directions are not intended to literally accept or limit the invention in any form. Furthermore, terms such as "first," "second," "third," etc., are used herein for illustrative purposes and are not intended to indicate or imply importance or significance.

[0018] See Figure 1 , Figure 2 As shown, the anti-rotation medical wristband with integrated ECG monitoring function of the present invention includes a wristband body 1 and a functional box 2 that can form a closed loop connection. The wristband body 1 is woven from an SMPU matrix 11 and shape memory alloy wires 12. Shape memory polyurethane (SMPU) is a smart polymer material that has the ability to recover its original shape under external stimuli (temperature, etc.). The addition of shape memory alloy wires 12 can further enhance the ability to recover the original state. When worn, when the patient's movement causes the wristband to deform, it triggers the tendency of the SMPU matrix 11 and shape memory alloy wires 12 to recover their original state. That is, the patient's wrist movement creates numerous positive forces driving the wristband. Correspondingly, the SMPU matrix 11 and shape memory alloy wires 12 generate numerous reverse forces with forces and directions opposite to the positive forces, thereby realizing dynamic adjustment of the inner circle curvature and fitting pressure, achieving "adaptive shaping with muscle activity". This not only completely eliminates circumferential rotation, but also adjusts the fitting tightness according to the patient's activity state (lying down / turning over / restlessness), avoiding pressure sores and obstruction of blood circulation.

[0019] The inner ring of the wristband body 1 facing the human body integrates a coplanar electrode array and a micro electromyography sensor array. The electrode array collects electrocardiogram (ECG) signals in real time, and the micro electromyography sensor array collects wrist muscle tension signals in real time. The signal-to-noise ratio of the ECG signal can be improved to over 95dB. At the same time, it supports the use of electromyography signals to help determine the patient's agitation level and provides data reference for sedation treatment.

[0020] Considering the different thicknesses of the wrists, the main body 1 of the wristband can be designed as an adjustable length style with holes and pins.

[0021] Functional box 2 integrates an intelligent main control module 21, a wireless energy data transmission module 22, and a parameter detection module 23. The intelligent main control module 21 is pre-trained with a clinical diagnostic model. The clinical diagnostic model integrates ECG, EMG, and biochemical indicator data in real time to automatically identify abnormal states such as arrhythmia, myocardial ischemia, and hyperlactatemia and execute graded early warning pushes. The graded early warning push includes: mild abnormalities are pushed to the responsible nurse's mobile terminal, and severe abnormalities trigger ward audible and visual alarms, emergency pop-ups on monitors, and early warnings on the doctor's workstation, forming a three-level early warning system of "end-edge-cloud".

[0022] The wireless power data transmission module 22 is a magnetic resonant coupling module integrating magnetic resonant wireless power supply and data transmission functions. Currently, wireless power and data transmission technology via magnetic resonance has made significant progress. For specific implementation details of the magnetic resonant coupling module, please refer to the relevant technologies in published patents CN120528124A (A magnetic coupler, wireless transmission system, and parameter optimization and efficiency tracking method) and CN108282029A (An implantable medical device based on wireless power transmission technology). The magnetic resonant coupling module enables continuous contactless power supply over a certain distance (≤5cm), while simultaneously utilizing signal modulation technology in the magnetic resonant frequency band to achieve high-speed synchronous transmission of ECG / EMG / identity data (transmission rate ≥1Mbps).

[0023] Furthermore, the wireless energy data transmission module 22 also includes a 5G communicator and a wireless WiFi communicator.

[0024] When a patient experiences cardiac arrest, the wristband identifies the patient via ECG signal. Function box 2 then immediately sends the location and patient data to the nearest defibrillator base station via the intelligent main control module 21 and 5G communicator. The defibrillator automatically turns on and plans the optimal access route. At the same time, it sends emergency instructions to the medical staff's wristband, displaying key information such as the patient's identity, allergy history, and past medical history, thus gaining valuable time for cardiopulmonary resuscitation.

[0025] When a patient is discharged from the hospital, the functional box 2 switches to home health management mode through the intelligent main control module 21 and the wireless WiFi communicator. It automatically connects to the home smart medical terminal, adjusts the monitoring frequency and early warning threshold, and synchronizes the data to the hospital's chronic disease management platform. Doctors can remotely view the patient's home electrocardiogram and biochemical data to achieve continuous management of "precise diagnosis and treatment in the hospital + long-term follow-up outside the hospital".

[0026] The parameter detection module 23 employs a magnetically plug-and-play disposable microfluidic chip in conjunction with a miniature optical detector. It allows for rapid replacement of detection chips for blood glucose, lactate, and troponin I (cTnI), enabling quantitative detection of these substances. For details on the implementation of the disposable microfluidic chip, please refer to the relevant technology in the published patent CN212975169U (Disposable Injectable High-Efficiency Microfluidic Detection Chip). After a patient's fingertip blood is dripped into the chip, the built-in miniature optical detector in the functional box 1 completes the quantitative detection. The data is then fused with the electrocardiogram signal and uploaded to the monitoring system, achieving integrated "electrophysiological monitoring + biochemical detection," which is particularly suitable for continuous monitoring of patients with comorbidities such as myocardial infarction and diabetes.

[0027] Furthermore, Figure 3 The diagram shows a structural schematic of a disposable microfluidic chip modified from existing technology. The disposable microfluidic chip has a built-in RFID traceability tag 231, which automatically records the detection time, chip batch number and detection results, avoiding the risk of hospital-acquired infections and data fraud. The chip can be removed and discarded with one click after use, without the need for cleaning and maintenance.

[0028] The above are merely preferred embodiments of the present invention and are not intended to limit the implementation methods and protection scope of the present invention. Those skilled in the art should recognize that any equivalent substitutions and obvious changes made based on the description and illustrations of the present invention should be included within the protection scope of the present invention.
