Detailed Description
Specific embodiments of the present utility model will be described in detail below with reference to the accompanying drawings. It should be noted that the technical features or combinations of technical features described in the following embodiments should not be regarded as being isolated, and they may be combined with each other to achieve a better technical effect.
Fig. 1 is a schematic diagram showing a circuit composition of an electrocardiographic monitoring device according to an embodiment of the present utility model.
As shown in fig. 1, the electrocardiograph monitoring device provided by the utility model comprises a microprocessor 1, an electrocardiograph acquisition circuit 2, a display circuit 3, a power management circuit 4, a storage circuit 5, an alarm circuit 6 and a sensor 7, wherein the electrocardiograph acquisition circuit 2, the display circuit 3, the power management circuit 4, the storage circuit 5, the alarm circuit 6 and the sensor 7 are all connected with the microprocessor 1.
The microprocessor 1 is used for processing and analyzing the acquired electrocardio analog signals, the processing and analyzing comprises filtering and denoising of electrocardio signals, analog-to-digital signal conversion, heart rate calculation and the like, and the processed and analyzed information can be displayed in the display circuit 3 and stored in the storage circuit 5. The microprocessor 1 is specifically an MCU chip of STM32F407 model.
In the case of detecting the electrocardiographic signals of the human body, since the electrocardiographic signals are weak millivolt signals emitted by the human body, a great amount of noise existing in the environment where the human body is located may submerge the weak electrocardiographic signals, and the sampling voltage of the analog-to-digital conversion circuit in the microprocessor 1 is generally volt-level, the electrocardiographic acquisition circuit 2 needs to include a circuit unit such as a pre-filtering circuit and an amplifying circuit.
Referring to fig. 2, the electrocardiograph acquisition circuit 2 includes an electrode and a filtering amplification circuit 10, the electrode includes a left-hand electrode 11, a right-hand electrode 12 and a feedback electrode 13, the filtering amplification circuit includes a high-pass filtering circuit 14, a low-pass filtering circuit 15 and an amplification circuit 16 which are sequentially connected, the left-hand electrode 11 and the right-hand electrode 12 are respectively connected with the high-pass filtering circuit 14, and the amplification circuit 16 is connected with the microprocessor 1. The frequency of the collected electrocardiosignal is generally between 0.05 and 100Hz, but most of energy is between 0.5 and 40Hz, and in order to ensure that signals with the frequency between 0.5 and 40Hz can be obtained, the signals outside the frequency band are removed by using the high-pass filter circuit 14 and the low-pass filter circuit 15, so that noise interference is reduced. Thus, although a part of effective electrocardiosignals are lost, the aim of basically obtaining the electrocardiosignals is not affected, and the electrocardiosignal denoising processing is more convenient. In order to suppress common mode interference and provide a high common mode rejection ratio, an AD8232 chip is selected as the filter amplification circuit chip.
Further, the electrode is a detachable soft electrode with the surface plated with Ag-AgCL and coated with conductive paste, and the electrode can minimize the DC drift potential as far as possible and offset the signal interference generated by the polarization voltage as far as possible.
The display circuit 3 is used for displaying the obtained electrocardiosignal information results such as heart rate and the like after the electrocardiosignal data are analyzed and processed by the microprocessor 1, so that a user can conveniently know the electrocardiosignal conditions in real time and find problems in time.
The power management circuit 4 is used for providing stable power for each circuit, so that the system can be ensured to normally operate. The power management circuit 4 is specifically a voltage stabilizing chip of the AMS1117 type, and is powered by a two-way power supply, and when a certain circuit fails, the system can normally operate, so that the stability of the power supply can be ensured.
Although the microprocessor 1 is a SRAM memory with a certain capacity, the capacity of the microprocessor is small, and therefore, the microprocessor cannot meet the requirements of a large amount of operations and graphic display of the device, so that a storage circuit 5 is additionally added in the device for storing electrocardiographic data with a large data amount and corresponding graphic data.
In order to enable the user to know the corresponding situation in time when the electrocardiosignal is abnormal, an alarm is sent out through the alarm circuit 6 when the electrocardiosignal is detected to be abnormal. The alarm circuit 6 specifically includes a buzzer. Through the sound of the buzzer, a user can sense the abnormal condition of the electrocardiosignal of the user, and the abnormal specific condition is known through checking the display circuit 3, so that certain measures can be taken conveniently.
When the user moves severely, motion pseudo noise is introduced, and the electrocardiosignals are distorted and lose use value in severe cases, in order to prevent the electrocardiosignals from being judged as invalid electrocardiosignals, the electrocardiosignal monitoring circuit is introduced with a sensor 7 to monitor the motion intensity of the user, when the sensor 7 judges that the motion intensity of the user is greater than a certain threshold value, the electrocardiosignal data acquisition at the moment is judged to be invalid, and only when the sensor judges that the motion intensity of the user accords with a certain threshold value condition, the electrocardiosignals are normally acquired for calculation, display and alarm. The sensor 7 is specifically a six-axis sensor of MPU6050 model.
The electrocardio monitoring equipment further comprises a key circuit 8 for controlling the electrocardio monitoring equipment, the key circuit 8 is connected with the microprocessor 1, and the key circuit is used for starting, shutting down, restarting and other operations of the electrocardio monitoring equipment, so that the equipment is controlled.
The electrocardiographic monitoring device further comprises a communication circuit 9 for communicating with an external device, and the communication circuit 9 is connected with the microprocessor 1. The communication circuit 9 includes a bluetooth module, a WiFi module or a 5G communication unit, and communicates with an external device through the bluetooth module, the WiFi module or the 5G communication unit, so as to transmit electrocardiograph signal data to the external device, where the external device may be an external server or an intelligent device of a user, so that the system is convenient to collect electrocardiograph signal data of the user or other users are convenient to know the electrocardiograph signal data in real time.
By means of the electrocardiograph monitoring device provided by the utility model, electrocardiograph signals of a user can be monitored and checked in real time, dangers are prevented, and meanwhile, the electrocardiograph monitoring device has the advantages of small size and long-term monitoring, and is convenient and easy to carry.
