Problems solved by technology

However, for the measurement of animals or human bodies, a single excitation coil and a single detection coil are mostly used to measure the brain coaxially. There are uneven excitation magnetic fields, fast attenuation, limited measurement depth, and are susceptible to interference from various environments and temperatures, especially the living body itself. A series of problems such as the influence of physiological activities, and the inability to locate the location of bleeding

Abstract

The invention discloses a non-contracting magnetic induction type detecting system of cerebral hemorrhage. The non-contracting magnetic induction type detecting system of the cerebral hemorrhage comprises a signal generator, a helmholtz upper coil, a helmholtz lower coil, a left cerebral hemisphere detecting coil, a right cerebral hemisphere detecting coil, a first data collecting card, a second data collecting card, a tee joint and a phase discriminator main machine, wherein the helmholtz upper coil and the helmholtz lower coil are correspondingly arranged in parallel, the space between the helmholtz upper coil and the helmholtz lower coil is a detecting space of the head, the distance between the helmholtz upper coil and the helmholtz lower coil is equal to the radius of a coil, the left cerebral hemisphere detecting coil and a right cerebral hemisphere detecting coil are arranged in the detecting space of the head in a movable mode and the positions of the left cerebral hemisphere detecting coil and the right cerebral hemisphere detecting coil are symmetrical relative to the sagittal suture of the head. The non-contracting magnetic induction type detecting system of the cerebral hemorrhage is high in detection sensitivity of early-stage hemorrhage, accurate in location, deep in detection depth, strong in antijamming capability, in a non-contracting magnetic induction type, and beneficial to bedside intensive care.

Description

technical field [0001] The invention relates to the technical field of medical equipment, in particular to a non-contact magnetic induction cerebral hemorrhage detection system capable of measuring the location and severity of cerebral hemorrhage. Background technique [0002] Cerebral hemorrhage and cerebral ischemia are collectively referred to as cerebral apoplexy, which is characterized by high incidence, high recurrence rate, high disability rate, high mortality rate and heavy economic burden. The incidence of cerebrovascular disease in my country is increasing year by year, with an annual increase of 8.7%, even catching up with the growth rate of "GDP". According to statistics, there are about 2 million new strokes in my country every year, and nearly half of them die. Among the surviving stroke patients, about 3 / 4 have lost their ability to work to varying degrees, and the severely disabled account for about 40%. . Stroke has become a serious global problem. Cerebra...
