Implantable recyclable pulmonary vessel pressure sensor and use method thereof

Abstract

An implantable recyclable pulmonary vessel pressure sensor is characterized in that a group of nickel-titanium hyperelastic alloying metal wires is connected in an end-to-end manner to form a self-expanding oval support, a pressure sensor is arranged on any one of the nickel-titanium hyperelastic alloying metal wires of the self-expanding oval support, and a tail hook is arranged at one end of the self-expanding oval support. The self-expanding oval support with the pressure sensor reaches a lesion site through a press holding type delivery catheter, and after fixation is released, the pressure sensor is capable of sensing pressure signals of monitoring sites continuously; when a reader is implanted on the chest skin, real-time pressure signals and measured values can be monitored and displayed through a pressure sensing system in the reader, the reader can be connected to a pressure analyzer through a needle hole connection jack at the bottom end of the reader, the pressure signals can be printed in real time through the pressure analyzer, all pressure records in the reader are stored, and the self-expanding oval support can be recycled at any time through the tail hook. The implantable recyclable pulmonary vessel pressure sensor and a use method thereof have the advantages of simplicity in operation, small test result errors, no pain on patients, low cost, accurate results, wide application and continuous replacement of existing materials.

Description

technical field [0001] The application belongs to the field of telemetry systems of medical devices, and in particular relates to an implantable retrievable pulmonary blood vessel pressure sensor and its application method. Background technique [0002] With the development of social urbanization, science and technology, and humanization, the national pharmaceutical industry has developed vigorously, followed by the increase in the use of telemetry systems for medical devices and the emergence of harsh operating conditions, large errors, and high prices. The working principle of the implantable telemetry system is to integrate the physiological signal acquisition and sending device into a very small electronic transmitter, and use its transmitting function to send the collected physiological signal to the signal receiver by wireless transmission, and the receiver After data conversion, the signal is transmitted to the software for analysis, which realizes the real-time data ...
