AI Technical Summary

Technical Problem

The lack of accurate methods for measuring dissolved oxygen, carbon dioxide, and other indicators in the blood before and after thrombosis in current technologies leads to poor prognosis for patients after mechanical thrombectomy and affects their quality of life.

Method used

Design an interventional guidewire device, with first and second blood oxygen measurement units on the guidewire body to measure blood oxygen data at the distal and proximal ends of the thrombus, respectively, and transmit the data to an external detection device for blood oxygen saturation calculation via a signal transmission unit.

Benefits of technology

It provides accurate blood oxygen saturation data, helping doctors assess thrombosis status and develop personalized treatment plans, avoiding unnecessary surgery and improving patient prognosis.

Abstract

The invention provides an interventional guide wire device for measuring blood oxygen saturation in a blood vessel, and belongs to the technical field of interventional operation medical instruments, the guide wire device comprises a guide wire body, a first blood oxygen measuring part and a second blood oxygen measuring part, the guide wire body is of a filiform structure and is provided with a far end and a near end; the first blood oxygen measuring part is arranged at a position which is a set distance away from the far end of the guide wire body and is used for measuring blood oxygen data of the far end of a thrombus; the second blood oxygen measuring part is arranged at the near end of the first blood oxygen measuring part, a set distance is formed between the second blood oxygen measuring part and the near end of the first blood oxygen measuring part, and the second blood oxygen measuring part is used for measuring blood oxygen data of the near end of thrombus; during working, the far end of the guide wire body penetrates through a thrombus, the first blood oxygen measuring part is arranged at the far end of the thrombus, and the second blood oxygen measuring part is arranged at the near end of the thrombus, so that blood oxygen data at the two ends of the thrombus are measured; the technical problem that blood oxygen indexes at the front end and the rear end of a thrombus cannot be evaluated before a mechanical thrombus extraction operation in the prior art is mainly solved.
