For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.
[0039] like Figure 1 As shown, a vital sign monitoring clothing system includes a garment body, an electrocardiogram monitoring unit, a respiratory monitoring unit, a body temperature monitoring unit, an integrated control unit, and a data processing terminal. The electrocardiogram monitoring unit, the respiratory monitoring unit, and the body temperature monitoring unit are fixed to the garment body and can conform to the garment. The electrocardiogram monitoring unit, the respiratory monitoring unit, and the body temperature monitoring unit are electrically connected to the integrated control unit to achieve power acquisition and data collection.
[0040] The ECG monitoring unit uses a dual-channel four-electrode ECG monitoring method for motion status to monitor ECG and heart rate. The four electrodes are located on the upper left chest, upper right chest, lower left abdomen and lower right abdomen of the top body.
[0041] The respiratory monitoring unit includes a respiratory sensor; the respiratory sensor is an elastic cloth-based bending sensor, which is located on the left side of the chest of the top body near the armpit, where the deformation is most obvious when the human body breathes; the respiratory sensor is fixed to the top body by edge stitching to monitor the respiratory rate.
[0042] The body temperature monitoring unit includes a body temperature sensor. The body temperature sensor is a thermistor (Negative Temperature Coefficient, NTC). NTC thermistors refer to thermistors with negative temperature coefficients, which have the characteristics of small size, fast response, high sensitivity, and small fluctuations in temperature characteristics. Medically, the temperature of the human armpit is most similar to the human body temperature, so the NTC thermistor is placed under the left armpit, and the same elastic fabric as the clothes is used. The body temperature sensor is fixed to the upper body by double-sided hot melting to monitor the body temperature.
[0043] The integrated control unit is placed in the side pocket on the left waist of the jacket body. There is a hole in the side pocket for passing the connecting wire. A side pocket cover is sewn above the side pocket. The side pocket cover and the side pocket can be closed with Velcro to prevent the integrated control unit placed therein from falling when the human body is moving. The integrated control unit includes a shell and a circuit board fixed in the shell, as well as a data acquisition module, a wireless communication module and a power module integrated on a circuit board. There are two interfaces on the integrated control unit, one is a USB female port, which supplies power to each data acquisition module; the other is a terminal wire female head, which is connected to the summary wire of the ECG electrode, temperature sensor and respiratory sensor connecting wire, and is used to receive the signals collected by the ECG electrode, temperature sensor and respiratory sensor, and transmit the signals to the data acquisition module.
[0044] The material of the jacket body is 75% nylon and 25% spandex. The jacket body is used as a base body, and an electrocardiogram monitoring unit, a respiratory monitoring unit, a body temperature monitoring unit and an integrated control unit are integrated and fixed.
[0045] like Figure 2As shown, the ECG monitoring unit includes an ECG electrode, a sponge layer and a protective layer; the sponge layer is sandwiched between the upper body and the ECG electrode to increase the contact pressure between the ECG electrode and the skin, thereby increasing the accuracy and reliability of the detection, and ensuring that the ECG signal of the human body can still be monitored in the state of motion; the protective layer wraps the ECG electrode and the sponge layer around the edge of the ECG electrode, and is firmly bonded to the upper body, and the material of the protective layer is similar to that of the upper body. A thin copper sheet is welded at the connection between each ECG electrode and the wire to ensure that the wire is firmly connected to the ECG electrode. The ECG electrode is made of nano-silver fiber material, which can achieve efficient detection of human ECG signals.
[0046] The data acquisition module includes an ECG signal acquisition chip, and a respiration and body temperature signal acquisition chip. ECG and heart rate signals are acquired through the ECG signal acquisition chip, KS1081; the body temperature sensor and the respiration sensor share a common acquisition chip, PCAP01, which can greatly save circuit design difficulty and space, and is more conducive to system miniaturization design. The acquisition chip has two on-chip resistor elements for measuring temperature, one of which is a chip-built-in resistor, located inside the chip, and is a fixed resistor with a fixed resistance value; the other is located outside the chip, and the resistance value can be changed according to demand.
[0047] The ECG acquisition chip is electrically connected to the ECG electrodes, and is used to acquire ECG signals and convert them into ECG vital signs data information; the respiration and body temperature signal acquisition chip is electrically connected to the respiration sensor and the respiration sensor respectively, and is used to acquire respiration signals and body temperature signals, and convert respiration signals and body temperature signals into respiration vital signs data information and body temperature vital signs data information. The respiration sensor uses a bending sensor, which produces elastic deformation under the action of respiration, causing the resistance strain gauge (conversion element) attached to its surface to also deform. After the resistance strain gauge is deformed, its resistance value will change (increase or decrease), and then the corresponding measurement circuit will convert this resistance change into an electrical signal (voltage or current), thereby completing the process of converting the respiration signal into an electrical signal. Specifically, the signal acquisition process of the body temperature sensor and the respiration sensor is as follows: Figure 3 As shown, the temperature and breathing data are first collected through the body temperature sensor and the bending sensor, and then the two sets of signals are time-aligned and sent to the digital signal processing chip for signal preprocessing to extract high-quality characteristic signals. The characteristic signals are then transmitted to the microcontroller through the SPI serial port communication. Finally, combined with the low-frequency characteristics of the signal, the high-frequency noise is filtered out through a low-pass filter to obtain the final target signal, that is, the respiratory sign data information.
[0048] The wireless communication module includes two universal asynchronous receiver-transmitters and a Bluetooth chip; the two universal asynchronous receiver-transmitters communicate directly with each other. The universal asynchronous receiver-transmitters convert the parallel data from the control device into serial form, and then transmit it serially to the receiving end, and then the receiving end converts the serial data back into parallel data for use by the receiving device. The Bluetooth chip is connected to the data processing terminal via Bluetooth, and is used to transmit the vital sign data information to the data processing terminal via Bluetooth communication, such as Figure 4 shown.
[0049] The data processing terminal receives the vital sign data information transmitted by the integrated control unit through Bluetooth communication and performs real-time monitoring. The data processing terminal can be a smart mobile terminal or a computer terminal. Among them, the smart mobile terminal processes the data and monitors it in real time through the application installed on the smart mobile terminal, and the computer terminal processes the data through the Lab View host computer and monitors it in real time through the computer.
[0050] The system uses the garment as a platform, integrates ECG, respiration, and body temperature monitoring units, realizes multi-modal continuous real-time monitoring of vital sign data information such as ECG, heart rate, respiration rate, and body temperature, integrates data acquisition modules and wireless communication modules, connects to smart mobile terminals and / or computer terminals, and performs real-time display and monitoring of vital sign data information.
