The magnetocardiogram has important clinical application value in the aspects of ischemic heart disease, ventricular hypertrophy diagnosis, bypass positioning of pre-excitation syndrome, diagnosis of fetal myocardial hypertrophy, arrhythmia and the like.
The magnetocardiogram signal of human body is very weak, and its maximum value is about tens of pitts (10-12T) which is nearly a million times weaker than the geomagnetic field, and generally requires measurement using a highly sensitive sensor in a magnetically shielded environment. Early detection was performed using a Superconducting Quantum Interference Device (SQUID), but SQUID equipment was complicated and expensive to purchase, operate and maintain, making magnetocardiography difficult to popularize.

Therefore, the buckle type heat insulation wearable system for measuring the magnetocardiogram of the human body is provided, and the magnetocardiogram can be acquired more conveniently and efficiently with high reliability.
At present, the patents related to the magnetocardiogram measuring device mainly include two types, the first type is that a superconducting quantum interferometer is used to obtain the magnetocardiogram, for example, patent "CN 201410504970.5", the content is that the superconducting quantum interferometer replaces the traditional electric measuring sensor to be used as a heart weak magnetic signal measuring probe, the heart weak magnetic signal detection sensitivity and precision are improved, and the magnetocardiogram is obtained; the second category is mainly the acquisition of magnetocardiograms using atomic magnetometers, for example, patent "CN 201811478462.9" proposes a method for detecting magnetocardiograms using atomic magnetometers. However, the SQUID used in the former has the disadvantages of complicated equipment and high purchase, operation and maintenance costs, and the atomic magnetometer used in the latter is mounted on a rigid detection frame and cannot be attached to the skin of a human body for measurement.
In conclusion, with the development and application popularization of the magnetocardiogram technology, a wide prospect is designed for the magnetocardiogram measuring system, and the research practice in this aspect is still relatively lacked.
