A snap-on heat-insulating wearable system for human magnetocardiogram measurement

Abstract

The invention discloses a buckle-type heat-insulation wearable system for measuring the magnetocardiogram of the human body, belongs to the field of biomedical engineering, and relates to a medical device. The system comprises a flexible clothes body, a buckle-type clamping groove, a heat-insulation layer and a sensor for measuring an extremely-low-intensity magnetic field, wherein the clothes body is made from a material of foamed rubber, and sticks close to the skin, no relative slide of parts of the clothes body is caused easily, and circular holes which are formed and distributed in an array are designed in the part, corresponding to the position of the heart, of the clothes body; the clamping groove comprises a base, a compression ring and a buckle-type cover, the base passes throughthe circular holes of the clothes body, and is fixed to the clothes body through the compression ring, and the buckle-type cover is used for fixing the sensor for measuring the extremely-low-intensitymagnetic field; and the aerogel heat-insulation layer of a certain area is placed between the clothes body and the skin of the human body, so that overheating damage to the skin of the human body isprevented. The buckle-type heat-insulation wearable system can be applied to multiple people through design of multiple clothes bodies of different size, measured parts can be selected flexibly through the plug position of the sensor, and the buckle-type heat-insulation wearable system has low-cost, high efficiency and high practicability, and can be applied to measurement of the magnetocardiogramof the human body.

Description

technical field [0001] The invention belongs to the field of biomedical engineering and relates to a medical device, in particular to a buckle-type heat-insulating wearable system for magnetocardiogram measurement of a human body. Background technique [0002] Magnetocardiography (MCG) is a non-contact, non-invasive biomagnetic field measurement method. Compared with ECG signals, ECG signals contain valuable information such as physiological processes and pathology, and signal transmission is not affected by biological processes. Influenced by changes in tissue conductivity, the intensity is relatively stable, the transmission is simple and the magnetic field can be precisely positioned, and at the same time it can give time-domain related information. Magnetocardiography has important clinical application value in the diagnosis of ischemic heart disease, ventricular hypertrophy, bypass of pre-excitation syndrome, fetal myocardial hypertrophy and arrhythmia.

Problems solved by technology

However, the SQUID used in the former has the disadvantages of complex equipment, high purchase, operation and maintenance costs, and the atomic magnetometer in the latter is installed on a rigid detection frame, which cannot fit the human skin for measurement

[0006] In summary, with the development of magneto-encephalographic technology and the popularization of applications, there are broad prospects for the design of magnetocardiogram measurement systems, but research practices in this area are still relatively lacking.
