Aorta blood pressure controlled release medicine carrying support and blood pressure control medicine release system

Abstract

The invention provides an aorta blood pressure controlled release medicine carrying support and a blood pressure control medicine release system, and belongs to the technical field of endovascology. The aorta blood pressure controlled release medicine carrying support comprises a support body, a lining laminating film, a conductive medicine carrying laminating film, a pressure sensitive resistor and a power source; the lining laminating film wraps the inner surface of the support body, and the conductive medicine carrying laminating film wraps the outer surface of the support body; the power source, the pressure sensitive resistor and the support body are connected to form a loop, when pressure borne by the pressure sensitive resistor is larger than a threshold value, the resistance is lowered, micro current exists in the loop, and medicine release is promoted through the conductive medicine carrying laminating film, and micro current can be transmitted to the body surface. The aorta blood pressure controlled release medicine carrying support can perform non-invasive monitoring on aorta blood pressure of a patient, evaluation is performed on the treatment effect of the aorta interlayer, risk early warning is performed, and meanwhile preventive accurate medicine treatment can be performed on the local lesion.

Description

technical field [0001] The invention relates to the technical field of aortic blood pressure monitoring, in particular to an aortic blood pressure controlled release drug-loaded stent and a blood pressure controlled drug release system. Background technique [0002] Aortic dissection refers to aortic disease in which arterial blood enters the aortic wall through a breach in the aortic intima, causing the aortic media to separate from the aortic adventitia, resulting in a false lumen. At present, the treatment of aortic dissection can use aortic stents to reshape the aorta and at the same time block or partially block the blood flow of the false lumen, thus playing the role of treating aortic dissection. [0003] However, the occurrence of adverse events may seriously affect the therapeutic effect and prognosis of aortic dissection, such as the mismatch between the graft and the vessel wall, resulting in incomplete closure of the gap, abnormalities in the systemic or local bl...

Problems solved by technology

[0003] However, the occurrence of adverse events may seriously affect the therapeutic effect and prognosis of aortic dissection, such as the mismatch between the graft and the vessel wall, resulting in incomplete closure of the gap, abnormalities in the systemic or local blood system, or special dynamic characteristics ( Under the impact of blood flow (such as blood pressure fluctuations), the false lumen cannot be completely thrombosed (even without thrombus), and then may occur: 1) The blood flow of the true lumen cannot be restored, and the false lumen undergoes progressive tumor-like expansion; 2) The false lumen Blood supply from the distal rupture, new retrograde tearing dissection; 3) special form of false lumen thrombosis can lead to differences in the mechanical strength of the vessel wall, local fragile areas, etc.

[0004] Due to the inability to non-invasively monitor the patient's aortic blood pressure, it is difficult to evaluate the prognosis and risk of complications of endovascular exclusion of aortic dissection; at the same time, there is a lack of preventive and precise treatment of local fragile vessel walls in patients with hypertension means
