Description

technical field [0001] The invention relates to the technical field of current detection, in particular to a current peak detection device, a high-voltage generator and vascular calcification treatment equipment. Background technique [0002] Vascular calcification refers to the pathological process in which hydroxyapatite minerals are deposited in the vascular system. It is more common in atherosclerotic plaques, diabetes, aging and chronic renal failure, blood vessels and heart valves in uremia. Clinical and epidemiological data show that vascular calcification is a common clinicopathological manifestation in patients suffering from atherosclerosis, hypertension, diabetic vascular disease, vascular injury and chronic kidney disease, and is an important risk factor for cardiovascular events , present in 80% of vascular injuries and 90% of coronary artery disease. Vascular calcification in infancy, uremic arteriolar calcification, and calcified valvular disease can be life-...

AI Technical Summary

Problems solved by technology

The current vascular calcification treatment equipment does not have an electrode current sampling device, which cannot capture the peak current during treatment in real time, and cannot confirm the operation of the equipment and the treatment of the patient, so as to further analyze the treatment results. The treatment effect cannot be monitored in real time, and cannot be monitored in real time. During the treatment process, the patient's treatment status is monitored and the treatment strategy is adjusted in time, so it is difficult to guarantee the patient's treatment effect and safety

[0005] The existing scheme of adding sampling resistors in the high-voltage circuit will affect the original discharge circuit and cause potential safety hazards

The existing scheme of using external electrode current sampling equipment can be easily deployed in laboratory testing and verification, but it is difficult to be applied in actual use due to the generally high price of professional equipment and the large size of the equipment. And it is inconvenient to carry, difficult to implement, and difficult to use in the field

In the existing current transformer scheme, due to the presence of magnetic components in the transformer, there will inevitably be magnetic saturation, and the current measured during magnetic saturation has no reference significance. At the same time, there will be a certain hysteresis effect in the ferromagnetic components. phase difference
