Ultrasonic transcranial Doppler blood flow analysis calibration system

Abstract

The invention provides an ultrasonic transcranial Doppler blood flow analysis calibration system, comprising a blood flow simulation device and a probe installation device, wherein the blood flow simulation device comprises a water tank box, a DC power source, a microcontroller, a stepping driver and a stepping motor are fixed to a first side face of a supporting side plate of the water tank box,an input end and an output end of the stepping driver are electrically connected with the microcontroller and the stepping motor, a thread driving disk is arranged on a second side face of the supporting side plate, the center of the thread driving disk is fixedly connected with a motor shaft, an upper supporting seat fixed with the second side face is arranged below the thread driving disk, a lower supporting seat is arranged on the surface of a bottom plate of the water tank box, a thread is hanged in a thread guide groove of the thread driving disk, a thread is hanged with a lower guide wheel after bypassing a first upper guide wheel and upper and lower guide columns, the probe installation device comprises a back plate provided with a guide rail seat on the top face, and a six-degree-of-freedom adjusting bracket is fixed on the guide rail seat through a slide block. The system can simulate human blood flow parameters and realize the metering and measurement of blood flow parametersof a TCD instrument.

Description

technical field [0001] The invention relates to the technical field of measurement and detection, in particular to an ultrasonic transcranial Doppler blood flow analysis and calibration system. Background technique [0002] Ultrasonic transcranial Doppler blood flow detector (TCD for short) is a medical diagnostic instrument widely used in various large and medium-sized hospitals, used to provide real-time dynamic cerebral blood vessel hemodynamic data, has been widely used in neurology Examination and monitoring of patients in clinical departments such as internal medicine and surgery, intensive care unit, anesthesiology department, cerebral artery interventional treatment center and vascular surgery. TCD non-invasively detects the blood flow parameters of the brain base and carotid arteries under physiological and pathological conditions through the acquisition of brain ultrasound Doppler echo signals, and provides valuable information for the diagnosis and treatment of re...

AI Technical Summary

Problems solved by technology

[0004] In view of the fact that there is no relevant detection device to simulate and detect some physical quantities involved in the TCD instrument, such as blood flow parameters, it is necessary to study how to measure and detect the physical quantities of the TCD instrument, such as blood flow parameters, to achieve measurement detection and value traceability. In order to ensure the technical problems of accurate measurement value of TCD equipment and reliable product quality, the present invention provides an ultrasonic transcranial Doppler blood flow analysis calibration system
