Description

Technical Field

[0001] The present invention relates to the technical field of medical detection equipment, and in particular to a dynamic blood pressure monitoring system. Background Art

[0002] Dynamic blood pressure monitoring refers to continuously monitoring blood pressure changes over a period of time to gain a more comprehensive and accurate understanding of an individual's blood pressure. Traditional blood pressure monitoring is usually performed intermittently in medical institutions or at home, while dynamic blood pressure monitoring can provide more valuable information to help doctors make more accurate diagnoses and treatment recommendations.

[0003] The patent publication number CN215913397U is a nursing vest suitable for disabled people, which includes a nursing vest, a down insulation layer and an IV bottle hanging mechanism. The utility model can fill the down insulation layer with down through the set gap by pulling the first zipper head to slide up and down at the first zipper, so as to achieve the effect of keeping warm. By arranging the IV bottle hanging mechanism on the back of the nursing vest, the telescopic rod is pulled out of the telescopic rod placement box, and is stuck by the elastic button arranged on the outer side of the telescopic rod. The IV bottle is hung on the IV bottle hook, and it can be moved during the IV drip process, and there is no need to manually support the IV bottle, which is very convenient. By arranging multiple groups of drug placement pockets and instrument placement bags, it is very convenient for patients to take drugs, and instruments such as blood pressure measurement can be placed in the instrument placement bag, and can be measured anytime and anywhere, which is convenient for recording the patient's physical condition.

[0034] Among them, the remote data center 7 is a system architecture that can support all terminal services of the main control module 2, and adopts a commercial cloud computing model to realize virtual services. The main control module 2 and the remote data center 7 communicate using the NB-IoT protocol. The NB-IoT wireless communication is based on the Internet of Things communication technology of the LTE network, using a bandwidth of 1.4MHz, supporting a large number of low-power devices, and the physical layer of the communication uses the LTE air interface, including OFDM, MIMO and 256QAM technologies, providing higher data transmission rates and lower bit error rates. The protocol layer of NB-IoT communication is based on the LTE protocol stack, including PDCP, RLC, MAC and PHY, etc. Its protocol layer supports two-way communication between devices and can support a large number of concurrent connections.

[0035] Specifically, the sensors in the blood pressure detection component 3, the body temperature detection component 4, the respiration detection component 5 and the heart rate detection component 6 can accurately measure the blood pressure, body temperature, respiration rate and heart rate. Through calibration and filtering and other technical means, the accuracy and reliability of the measurement results are improved, and the appropriate time interval is set to trigger the sensors to measure the blood pressure, respiration rate, body temperature and heart rate. Ensure that the collected data has a certain degree of continuity and timeliness, process and analyze the collected data, including data conversion and analysis, and transmit the processed data to other devices, such as mobile phone applications, through Bluetooth wireless technology.

The detection body 31 is internally provided with a servo pressurized air pump, an electronically controlled exhaust valve, and an air pressure sensor.

[0039] In this embodiment, a servo pressurizing air pump, an electronically controlled exhaust valve, and an air pressure sensor are provided inside the detection body 31. The servo pressurizing air pump is used to pressurize at a uniform speed, and the blood pressure is measured by the air pressure sensor during the pressurization process to obtain the blood pressure and transmit the data to the main control module 2.

[0040] The sphygmomanometer can measure in two modes: autonomous operation and programmed operation. It can implement automatic pressurization and automatic pressure release without manual control. The measurement data can be displayed on the 8-screen display and can also be reported by voice.

[0041] like Figure 2 and Figure 3 As shown, the carrier 1 includes a vest 101, a first placement bag 102 and a second placement bag 103 are arranged on the vest 101, a partition 104 is arranged inside the cuff of the vest 101, and a body temperature detection component 4 is arranged between the vest 101 and the partition 104. The body temperature detection component 4 includes a galvanic integrated sensor 41 and an electric telescopic rod 42. The electric telescopic rod 42 is connected between the vest 101 and the partition 104, and the galvanic integrated sensor 41 is connected to one end of the electric telescopic rod 42.

After the measurement is completed, the patient's comfort is enhanced.

[0046] Specifically, a flexible graphene sensor 54 is used to monitor the respiratory rate. The sensor has good conformality and can be attached to the skin surface. The flexible graphene sensor is composed of a graphene film and an electrode, and the film is fixed on a flexible substrate. When the sensor is stretched, the lattice structure of the graphene film will deform, resulting in a change in the electron transport path.

[0047] like Figure 1 and Figure 2 As shown, specifically, the heart rate detection component 6 includes a heart rate belt 61 and a heart rate sensor 62. The heart rate belt 61 is arranged inside the vest 101, and the heart rate sensor 62 is arranged on the heart rate belt 61. The patient's heart rate is measured by the flexible heart rate sensor 62 to obtain heart rate data and transmit the data to the main control module 2.

[0048] Among them, the software system sets a timer task to trigger the measurement of blood pressure, respiratory rate and body temperature at a specified time interval. Before the measurement, the user is reminded by voice to relax and sit still (to avoid inaccurate blood pressure measurement). The collected data needs to be processed and analyzed in the system. Including data calibration, filtering, data conversion and data analysis to ensure the accuracy and reliability of the data. The processed data is transmitted to other devices via Bluetooth wireless technology. The Bluetooth communication protocol can be used to establish connections between devices and transmit data. During the data transmission and storage process, the software system needs to take security measures, including data encryption, identity authentication and permission control, to ensure the user's data security and privacy protection.

[0049] Specifically, an alarm is also provided on the main control module 2; the terminal needs to have a programmable mechanism for setting various measurement operation times or cycles (such as measuring blood pressure once every 2 hours, or collecting body temperature, etc.), and the terminal can also set an early warning threshold. When the collected data reaches the threshold range, the terminal will issue an early warning signal and send a message to the background (remote single management terminal). The measured and collected data is encapsulated by the protocol and transmitted in real time, and sent to the database specified by the system as a background data processing resource.

[0050] Working principle: The blood pressure detection component 3, the body temperature detection component 4, the respiration detection component 5 and the heart rate detection component 6 can be used to dynamically monitor the conventional physical parameters such as blood pressure, body temperature, respiration and heart rate of the subject in the autonomous activity scene.
