Abstract

The invention relates to a cardiovascular blood flow velocity sensor, which comprises a cardiovascular bracket and a flow velocity sensor. The cardiovascular bracket is a tubular film. The flow velocity sensor is on the inside surface of the tube wall of the cardiovascular bracket. The flow velocity sensor comprises a substrate, the surface of which is coated with a coat. An electrode is arrangedat the upper side of the substrate. According to the cardiovascular blood flow velocity sensor disclosed by the invention, the production process is simple; the cardiovascular blood flow velocity sensor has good biocompatibility, higher mechanical flexibility and corrosion resistance and excellent self-expansion property; the cardiovascular blood flow velocity sensor is beneficial to working in human body stably for a long time; the real-time measurement of cardiovascular flow velocity is realized; and the problems urgently needed to be solved in clinic are solved.

Description

technical field [0001] The invention relates to biomedical engineering, in particular to a cardiovascular blood flow velocity sensor, especially a sensor implanted in a coronary artery for measuring blood flow velocity and a manufacturing method thereof. Background technique [0002] Implantable medical devices refer to medical devices embedded in the human body, which can be used to measure and monitor the long-term changes of physiological and medical parameters in the human body, so as to realize the diagnosis and treatment of diseases, and realize the specific physiological parameters of the human body in an unrestrained natural state. real-time recording. This kind of device can also replace some human organs that have lost their original functions, such as kidney (Kidney), retina (Retina) and so on. Due to its prominent role, implantable medical devices have become an important part of biomedical research, and are also a hot direction for the development of biomedical...
