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.

Embodiment 1

[0028] figure 1 It is a structural diagram of a specific embodiment of a buckle-type heat-insulating wearable system for measuring magnetocardiogram of the human body, (a) is a schematic diagram of the work of the buckle-type heat-insulation wearable system, (b) is an array of clothing body slots schematic diagram.

[0029] In this example, if figure 1 As shown in (a), the subjects lie flat on the experimental table in the magnetic shielding room (bucket) and wear the buckle-type heat-insulating wearable system. Composed of flexible clothing body 1, airgel heat insulation layer 2, snap-on card slot 3, with an accuracy of 15fT / Hz 1 / 2 The flexible clothing body 1 is designed with a number of arrays of round holes corresponding to the position of the heart, and the airgel heat insulation layer 2 is placed between the human skin and the flexible clothing body 1. The card slot is composed of a base 5, a pressure ring 6 and a snap-on cover 7. The base passes through the round h...

Embodiment 2

[0031] The flexible clothing body 1 is made of tights made of foam rubber, which is close to the human skin and has a certain degree of elasticity, and is not easy to slide relative to the skin. The clothing body is designed with a number of arrays of round holes corresponding to the heart position, which are used to place snap-on Draw-in slot 3 is used to fix the extremely weak magnetic field measuring sensor 4, the spacing between the circular holes is 1cm and the relative position is not easy to change, and some clothes with different sizes can be designed to be suitable for most people.

Embodiment 3

[0033] The airgel insulation layer 2 is made by winding the airgel sheet with high-temperature tape. The high-temperature tape can be used normally within 200°C. The airgel heat insulation layer 2 can isolate the temperature of 200°C. Low, compared with traditional thermal insulation materials, under the same thermal insulation effect, the thickness of airgel material is only 1 / 2-1 / 5 of traditional thermal insulation materials, which can realize the extremely weak magnetic field measurement sensor 4 and human skin. The distance between them should be as short as possible. Since the airgel material is loose and fragile, it can be wrapped with high-temperature tape to avoid shape change, and the two materials are non-magnetic, which will not affect the measurement effect of magnetocardiography.

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. [0003] The hu...
