12-lead dynamic electrocardiogram transmitter

Abstract

The invention relates to a 12-lead dynamic electrocardiogram transmitter. Belongs to the technical field of electrocardio recorders. The 12-lead dynamic electrocardio transmitter comprises a shell and a PCB, the PCB comprises a digital area, an analog area and an electrocardio IC, the electrocardio IC is connected between the digital area and the analog area in a bridging mode, the digital area comprises a Type-C data interface, a Bluetooth IC, a storage and a card reading chip, the analog area comprises a spring contact pin and a second-order passive low-pass filter, the spring contact pin comprises a first-order passive low-pass filter, and the second-order passive low-pass filter comprises a second-order passive low-pass filter. The spring pin is used for transmitting human body electrocardiosignals to the second-order passive low-pass filter, the second-order passive low-pass filter is used for eliminating environmental interference and transmitting the electrocardiosignals to the electrocardiograph IC, the electrocardiograph IC is used for transmitting the received electrocardiosignals to the Bluetooth IC, the Bluetooth IC is connected with the memory, and the card reading chip is connected with the memory and the Type-C data interface. The 12-lead dynamic electrocardiogram recorder host is small in size, light in weight and more suitable for daily wearing and use, and does not cause great influence on normal life of a user.

Description

technical field [0001] The present invention relates to a 12-lead dynamic electrocardiogram transmitter. It belongs to the technical field of electrocardiogram recorders. Background technique [0002] ECG signal is one of the earliest bioelectrical signals studied and applied in clinic. It is easier to detect than other bioelectrical signals and has more intuitive regularity. It is still one of the important research objects in the field of biomedical engineering. The traditional way to measure ECG signals is to use an electrocardiograph (EKG), which patients must complete in a hospital, including a stress test. However, heart attacks are generally characterized by sudden, transient and dangerous characteristics. It is not something that you want to happen. The hospital's stress test, for example, allows users to run on a treadmill for 15 minutes, and encounters with patients in ordinary times. Physiological and psychological stress is still different. Therefore, it is ne...

Problems solved by technology

[0005] 2. Some existing dynamic ECG recorders use traditional 12-lead wires to connect to the human body, which is cumbersome to use and has a great impact on the normal life of users

[0006] 3. The existing dynamic ECG recorder is implemented with discrete components, resulting in a large volume and heavy weight of the host of the dynamic ECG recorder, which is inconvenient for daily wear and use

The dynamic ECG recorder generally uses a separate filter circuit, protection circuit, amplifier circuit and analog-to-digital conversion circuit to process the ECG signal. Each channel needs such a pre-circuit, which results in a dynamic ECG recorder The volume and weight of the host are relatively large, which is inconvenient to use and will affect the daily life of users
