Problems solved by technology
For these stents, the blood vessels can be dredged within a period of time after implantation, but restenosis often occurs after a long time, depending on the situation, and some even occur within a few months
For example, the coronary stent for the treatment of coronary heart disease, although it is one of the most effective means for the treatment of coronary heart disease, some patients may experience restenosis 6-8 months after implantation

The invention discloses a degradable flexible blood vessel detection device and system. The device comprises a flexible substrate, wherein the flexible substrate is used for holding connecting leads,a coil antenna and a capacitor; the flexible substrate also comprises a to-be-detected blood vessel fixing part; a strain resistor is positioned inside the to-be-detected blood vessel fixing part; theto-be-detected blood vessel fixing part and the strain resistor are both wound on a to-be-detected blood vessel; the leading leads are used for connecting the coil antenna, the capacitor and the strain resistor to form an LRC (inductor, resistor, capacitor) circuit; the coil antenna in the LRC circuit is used for receiving excitation signals transmitted from an external analysis device; and the external analysis device confirms change of resistance of the strain resistor according to reflection signals corresponding to the excitation signals, and furthermore, confirms whether the to-be-detected blood vessel has vascular thrombosis or not and the size of embolism in case of vascular thrombosis according to the change of resistance. By adopting the degradable flexible blood vessel detectiondevice and system disclosed by the invention, whether a blood vessel of a living body has embolism or not can be accurately confirmed in time.
Description
technical field [0001] The present disclosure relates to the technical field of flexible electronics, in particular to a degradable flexible blood vessel detection device and system. Background technique [0002] Vascular disease has always been a major disease that threatens human health. Thrombus, as one of cardiovascular diseases, is the basic cause of many diseases. The formation of thrombus is mainly formed by the interaction and mutual influence of genetic factors and environmental factors. When any of the conditions of vascular endothelial damage, slowed blood flow, and increased blood viscosity will increase the risk of thrombosis. Some small thrombi can be dissolved and absorbed in the body, while large thrombi are not easy to ablate, and even with the continuous washing, falling off, and collapse of the blood flow, some blood vessels are blocked, which poses a serious threat to life safety. [0003] In view of the above problems, it is very common in medicine to ...
