[0027] Electrocardiogram (ECG) is one of the most commonly used means for heart detection, and currently, the detection of electrocardiogram signals in hospitals is usually carried out by connecting a twelve-lead electrocardiogram machine to wet electrodes worn on the human body at fixed electrocardiogram signal collection positions. Since the application scene of the electrocardiogram machine in the hospital is too single, the electrocardiogram machine is used in hospitals and nursing homes to monitor the electrocardiogram of patients, and medical staff cannot real-time monitor the electrocardiogram of each patient. There are also electrocardiogram recorders with telemetry technology on the market, but such devices are usually large in size, inconvenient to wear, cannot be worn without feeling, affect the daily activities of users after being worn, and have poor user experience. The embodiment provides an electrocardiogram recorder based on telemetry technology, which is a wearable small device, convenient to wear and small in size, and on this basis, the telemetry technology can be used to monitor the real-time electrocardiogram data of patients in the hospital and transmit the data to a remote terminal, facilitate patient management and timely find abnormal conditions of patients.
[0028] The embodiment provides an electrocardiogram recorder based on telemetry technology, which comprises a mainboard module and a timing module, a power management module, an electrocardiogram acquisition module, a motion acquisition module, a data transmission module and a data storage module connected with the mainboard module.
[0029] The electrocardiogram acquisition module is an electrocardiogram monitoring sensor, which is used to collect body surface electrocardiogram signals in cooperation with electrocardiogram electrodes. The collected electrocardiogram signals can be stored in the data storage module and uploaded by wired transmission mode, or can be transmitted to a remote terminal in real time by the data transmission module to realize electrocardiogram telemetry.
[0030] Further, as shown in Figure 1 The electrocardiogram recorder further comprises a shell 1 for packaging the modules. The shell 1 is connected with an electrocardiogram electrode connector for connecting disposable electrocardiogram electrodes. The shell 1 can be molded at the bottom to directly connect the electrocardiogram electrodes with the bottom, or a detachable base can be provided, and the base is installed and cooperated with the shell 1 to connect the disposable electrocardiogram electrodes with the base to complete the assembly.
[0031] Preferably, the data transmission module comprises a 4G transmission unit and a WiFi transmission unit, which are used to transmit the electrocardiogram data collected by the electrocardiogram acquisition module to a remote terminal in real time. When the current scene is in a WiFi environment, the electrocardiogram data is transmitted to the remote terminal by the WiFi transmission unit, and when there is no WiFi in the current scene, the electrocardiogram data is transmitted to the remote terminal by the 4G transmission unit. The 4G transmission unit in the embodiment is a cat1 chip.
[0032] The electrocardiogram recorder further comprises a battery, which is connected with the power management module and packaged in the shell.
[0033] As an optional embodiment, the motion acquisition module includes a three-axis acceleration sensor and a three-axis gyroscope sensor, which are used for step counting and posture detection of the user, and are used for recording the motion, walking steps and posture of the patient when wearing the electrocardiograph, and detecting whether the patient falls or other conditions.
[0034] As an optional embodiment, the power management module includes a charging unit, a power statistical unit and a battery monitoring unit, as shown in the figure, the power management module of the embodiment selects ADI's MAX20360, which has a power consumption of less than 100 mu A, a package of 4.88 mm x 4.19 mm, a small space occupation, and at the same time has a multi-channel LDO, DC-DC for external use. Figure 3
[0035] As an optional embodiment, as shown in the figure, the timing module is an RTC chip, which is connected with the mainboard module and serves as a watchdog unit of the mainboard module. In the embodiment, the RTC chip uses RV-3028, which has the functions of RTC and active crystal oscillator, and can also be used as a watchdog of SOC. The single chip has multiple functions, small size (3.2 mm x 3.2 mm) and low power consumption (less than 1 uA). Figure 4
[0036] As an optional embodiment, the electrocardiograph further includes an RGB indicator light module, which includes three indicating states of red, green and blue, and is used for indicating the states of low power, charging, sufficient power and device abnormality. For example, in the embodiment, when the power is sufficient and the device is working normally, the indicator light is green; when charging, the indicator light is blue; and when the device is abnormal or the power is low, the indicator light is red.
[0037] As an optional embodiment, the data storage module is an SD card.
[0038] The telemetry-based electrocardiograph of the embodiment integrates multiple devices on the same mainboard SOC using high-integration devices, and uses a one-chip multi-function scheme for RTC and power modules, thereby saving the volume of devices in the shell and making the electrocardiograph more compact and improving the user experience. On the software level, the devices are put to sleep when idle to improve the running efficiency of the software and increase the idle time ratio to reduce the overall power consumption. For high-power devices such as SD cards and CAT1, in order to reduce the operation frequency, data caching is performed on the software level, and the data is operated when it reaches a certain degree. The amount of cached data is determined by the RAM of the SOC, and about 100 KB of cache space is used in the embodiment.
[0039] At the control strategy level, the CAT1 chip design controllable transmission interval, such as 30s-120s, the longer the time interval, the less the network connection times, so as to ensure that the system can get more sleep time to reduce power consumption. The number of times of writing to the SD card is also minimized to reduce the frequency of writing to the SD card to reduce power consumption.
[0040] Preferably, the ECG acquisition module, motion acquisition module and data transmission module are provided with independent power switches to realize separate opening or closing, when the function of a module is not needed, the module function can be closed through the software level to reduce power consumption. And for the acquisition module, the hardware FIFO is used to reduce the data acquisition frequency to ensure that the data sampling rate is not reduced, so as to reduce the interrupt frequency to the greatest extent, so that the system is less woken up to reduce power consumption.
[0041] The ECG recorder of the embodiment is miniaturized on the basis of ensuring the remote ECG function, emphasizes the user's non-sensing wearing, and further sets various optimization modes for reducing power consumption at the software and control levels, so that the ECG recorder can realize long-time standby, and more improve the user's use experience.
[0042] The above embodiment is a preferred implementation scheme of the utility model, in addition to this, the utility model can be realized in other ways, under the premise of not departing from the technical scheme concept, any obvious replacement is within the protection scope of the utility model.
