Description

Magnetic Resonance Charged Electrocardiograph

technical field

The utility model relates to the field of medical equipment, in particular to a magnetic resonance charging electrocardiograph.

Background technique

In my country, the death caused by cardiovascular disease accounts for about 40% of the total death rate, which poses a great threat to people's health. Cardiovascular disease is characterized by suddenness and danger, but studies by Norris et al. also pointed out that 72% of patients had obvious discomfort before cardiac arrest, and 70% of them had symptoms that lasted for more than 15 minutes. Therefore, real-time ECG monitoring of patients and timely detection of abnormal ECG changes are of great significance for the prevention and treatment of cardiovascular diseases.

Due to the solid-heart electrical monitoring of patients, the electrocardiograph is required to have battery life and to ensure that it will not be powered off during use. Therefore, the traditional electrocardiograph is usually connected to the mains through a power adapter, and continuously provides electric energy for the electrocardiometer through the mains.

Compared with the traditional electrocardiograph, the portable electrocardiograph can provide patients with all-weather, anytime, anywhere monitoring and protection functions. They usually have batteries that store electrical energy for continued use by the patient. However, after the battery of the portable electrocardiograph is exhausted, it also needs to be charged with an external mains power through a power adapter.

However, the length of the power adapter wiring is limited, which will limit the patient's activities in the area; at the same time, in the case of a large number of patients, there are not enough power sockets to charge multiple portable ECGs.

The input and output terminals of any field effect transistor are coupled with Zener diodes; the field effect transistor Q1 The input terminal of Q2 is connected to one end of the coil through the capacitor C1, and the input terminal of the field effect transistor Q2 is coupled to the other end of the coil.

Then, when the control poles of field effect transistors Q1 and Q2 are controlled so that field effect transistors Q1 and Q2 show regular changes, the coil generates a resonant magnetic field; the control poles of field effect transistors Q1 and Q2 are controlled by a PWM regulating circuit or a single-chip microcomputer That is, this embodiment is not limited.
