Title
(EN) Optical fiber guide wire for monitoring intravascular pressure and intravascular pressure detection device
(ZH) 用于监测血管内压的光纤导丝及血管内压检测装置
Abstract
(EN) The utility model discloses an optical fiber guide wire for monitoring blood vessel internal pressure and a blood vessel internal pressure detection device, the optical fiber guide wire for monitoring blood vessel internal pressure comprises a guide wire body, and the guide wire body is provided with a pressure measuring section. The pressure measuring section comprises a contact layer suitable for making contact with the wall of a blood vessel and a multi-core optical fiber located in the contact layer and suitable for collecting deformation data signals generated when blood flow impacts the contact layer after the guide wire body is inserted into the blood vessel. The blood vessel internal pressure measuring device can measure the blood vessel internal pressure, shortens the calibration time and improves the safety.
(ZH) 本实用新型公开了一种用于监测血管内压的光纤导丝及血管内压检测装置,用于监测血管内压的光纤导丝包括导丝本体,所述导丝本体具有测压段,所述测压段包括适于与血管管壁接触的接触层和位于接触层内并适于采集在导丝本体插入血管后血流流经时冲击接触层产生的形变数据信号的多芯光纤。本实用新型能够对血管内压进行测量,而且降低了校准时间,提高了安全性。
