Embodiment approach

[0030] As an embodiment of the present invention, a circular ring 400 is fixedly connected to the outer wall of the installation cylinder 100, and a circular ring 400 is fixedly connected to the outer wall of the installation cylinder 100, and the circular ring 400 is connected to the carotid artery stent The 500 is designed in one piece, and the device is placed on the lesion of the carotid artery through minimally invasive surgery. It can not only treat the primary carotid artery stenosis, but also detect whether there is restenosis at both ends of the blood vessel through the blood flow monitoring device.

[0031]As an embodiment of the present invention, the external processing device includes a second radio frequency transceiver module, a processor, a transmission module and a workstation, and the second radio frequency transceiver module transmits electromagnetic waves to the integrated circuit in the body to transmit energy, and at the same time Receive the blood flow ve...

Abstract

The invention relates to the technical field of medical monitoring, in particular to a blood flow velocity monitoring device and method based on a carotid artery stent. The monitoring device includesthe carotid artery stent, a flexible circuit board and external processing equipment, the carotid artery stent is used as an antenna, the flexible circuit board is provided with two integrated circuits, a mounting barrel is closed at the upper end, the own health condition can be clearly known, and when the stenosis or blockage of own blood vessels occurs, more accurate hemadostenosis lesion locations can be provided for doctors; and by inserting the mounting barrel into a round hole, a round ring is attached to the vessel wall, then the carotid artery stent and the round ring are attached andfixed to the vessel wall together through a femoral artery cannula in a minimally invasive surgery way, thus a blood flow velocity sensor and a blood pressure sensor are installed more conveniently in a more minimally invasive mode, and then surgical risks and complications are lowered.

Description

technical field [0001] The invention relates to the technical field of medical monitoring, in particular to a carotid stent-based blood flow velocity monitoring device and a method thereof. Background technique [0002] In recent years, vascular diseases have shown a high incidence trend, and vascular embolism is one of the important diseases. The main cause is that some lipids accumulate in the carotid intima to form white plaques, resulting in narrowing of the carotid artery lumen, blocking blood flow, and causing neck pain. ischemia. Carotid artery plaque is a manifestation of carotid atherosclerosis, which is more likely to occur at the bifurcation of the common carotid artery. It is currently considered to be closely related to the occurrence of ischemic stroke in the elderly. The mechanism of ischemic stroke may be as follows: carotid artery stenosis caused by plaque enlargement causes intracranial hypoperfusion and plaque detachment to form emboli, leading to intracr...
