Embodiment Construction

[0030] In order to make the object, technical solution and advantages of the present invention clearer, the present invention will be described in detail below in conjunction with the accompanying drawings and specific embodiments.

[0031] figure 1 As shown, the unshielded magnetocardiograph includes superconducting quantum interference device (SQUID), non-magnetic Dewar, flux-locked ring, signal amplifier, filter, data acquisition card, electrocardiograph, non-magnetic moving bed, expert Disease diagnosis software information systems and mainframes. The low-temperature superconducting quantum interferometer is used to replace the traditional electrical measurement sensor as the heart weak magnetic signal measurement probe to improve the detection sensitivity and accuracy of the heart weak magnetic signal.

[0032] When the heart beats, ions (such as Na+, K+) move across the cell membrane, and the ions inside and outside the cell membrane and their movement across the cell m...

Abstract

The invention discloses an unshielded magnetocardiogram instrument. The unshielded magnetocardiogram instrument comprises a superconducting quantum interfere device, a non-magnetic Duvel, a magnetic flux locking ring, a signal amplifier, a wave filter, a data acquisition card, an electrocardiograph, a non-magnetic moving bed, an expert disease diagnostic software information system and a master computer. Conventional electric measuring transducers are replaced by the superconducting quantum interfere device as a cardiac weak magnetic signal measuring probe; cardiac weak magnetic signal detection sensitivity and precision are improved; the unshielded magnetocardiogram instrument is the latest international noninvasive cardiac function inspection equipment, and is a novel noninvasive and hypersensitive inspection instrument provided for undiagnosed coronary heart disease patients; the unshielded magnetocardiogram instrument is popular among medical staff and patients, in particular to the patients who are not suitable for exercise tests and catheter inserting and fear of cardiac catheter inspection.

Description

technical field [0001] The invention belongs to the field of medical devices, in particular to a superconducting heart weak magnetic signal detection device, especially an unshielded magnetocardiograph, which aims at early and accurate diagnosis and screening of heart disease patients. Background technique [0002] The extremely consuming and stressful lifestyle in modern society has made heart disease one of the most common diseases. In order to facilitate the early diagnosis of heart disease, people urgently need a fast and accurate screening method. Especially for those with high risk factors of coronary heart disease (suffering from hypertension, hyperlipidemia, diabetes, obesity and other diseases and smokers) it has a very important role and significance. At present, the routine clinical diagnostic tools for heart disease mainly include electrocardiogram (ECG) and coronary angiography (CAG). [0003] As an effective means of diagnosing heart disease, electrocardiogram...
