Real-time fistula thrombus detection system, real-time fistula thrombus detection device and fistula thrombus blood flow velocity detection method

Abstract

The invention relates to an ultrasonic Doppler effect based real-time fistula thrombus detection system, a real-time fistula thrombus detection device and a fistula thrombus blood flow velocity detection method. The real-time fistula thrombus detection system comprises a master control module, an ultrasonic probe driving module, a dual-mode ultrasonic probe module, a display module, a wireless transmission module and a storage module. The display module, the storage module, the ultrasonic probe driving module and the wireless transmission module are directly connected with the master control module, the ultrasonic probe driving module is further connected with the dual-mode ultrasonic probe module, the wireless transmission module is used for remote data transmission through wireless signals, and the power supply module supplies power to each module. By different placement ways and two different operating modes of an ultrasonic probe, the problem of difficulty in determination of a Doppler angle in practical application to blood flow velocity measurement is effectively eliminated, and the problem of flow velocity gradient fuzziness is solved.

Description

technical field [0001] The invention belongs to the field of intelligent wearable electronic medical equipment, and in particular relates to a real-time detection system, a real-time detection device and a blood flow velocity detection method for internal fistula thrombus. Background technique [0002] Autogenous arteriovenous fistula (autogenous arteries-venous fistulas, AVF) is a common vascular access to maintain the life of hemodialysis patients. The number of hospitalizations caused by stenosis of vascular access or embolism of arteriovenous fistula after arteriovenous fistula operation accounts for 15%-24% of the total number of hospitalizations of dialysis patients. AVF dysfunction is one of the main causes of death in long-term dialysis patients. The International Kidney Foundation's clinical practice guidelines for vascular access suggest that dynamic monitoring of hemodynamic parameters can monitor the health of vascular access in a timely manner, and timely inter...
