Ultrasound transcranial Doppler blood flow detector and control method thereof

Abstract

The invention discloses an ultrasound transcranial Doppler blood flow detector and a control method thereof. The ultrasound transcranial Doppler blood flow detector comprises a case, a power source circuit and a plurality of ultrasonic probes. The detector comprises a tablet personal computer used for inputting information and displaying the detection information, and a detection circuit board, wherein the detection circuit board comprises a Doppler channel module, a Doppler control module, an A / D conversion module and an erasable and editable logic device, the output end of the Doppler channel module is connected with the input end of the Doppler control module, the output end of the Doppler control module is connected with the input end of the A / D conversion module, the output end of the A / D conversion module is connected with the input end of the erasable and editable logic device, and the output end of the erasable and editable logic device is connected with the input end of the Doppler control module. The detection circuit board is used for receiving Doppler signals and outputting the detection information to the tablet personal computer. The tablet personal computer and the detection circuit board are connected through a connector. The detector is easy to produce, low in open source cost of an operation system, small in size and convenient to move and carry.

Description

technical field [0001] The invention relates to a blood flow detector and a control method thereof, in particular to an ultrasonic transcranial Doppler blood flow detector and a control method thereof. Background technique [0002] Ultrasonic transcranial Doppler blood flow analyzer is a non-invasive detection method for cerebrovascular diseases that uses ultrasonic Doppler effect to detect the hemodynamics and physiological parameters of the main arteries of the skull base through the weak part of the skull. Based on the Le effect, it is a cerebral blood flow detection technology that applies computer technology to clinical medicine. TCD (transcranial Doppler, transcranial Doppler ultrasound) provides hemodynamic parameters that cannot be measured by imaging techniques such as MRI (Magnetic Resonance Imaging, magnetic resonance imaging), DSA (Digital subtraction angiography, digital subtraction angiography). One of the development directions of TCD is the research on the d...

Problems solved by technology

Portable portable TCDs refitted from notebooks and made by special mold opening are similar to bedside monitors. These two portable TCDs are only structural changes. They are still composed of TCD detection circuits and INTEL X86 computer boards running WIMDOWS operating systems. Composition, the power consumption is not low enough, and the volume is not small enough, which is not conducive to carrying when doctors make rounds, especially when doctors need to bring multiple devices
