Product Introduction
Working Principle:
The Ultrasonic Transcranial Doppler Blood Flow Analyzer utilizes the ultrasonic Doppler frequency shift principle to explore and measure blood flow movement information (excluding fetal applications), used for transcranial, neck, and peripheral vascular blood flow measurement, excluding diagnostic analysis functions.
TCD technology uses ultrasound to penetrate the skull's weak areas, combined with the Doppler principle, to perform real-time spectrum analysis of Doppler frequency shift echo signals from blood cells in vessels, enabling analysis of cerebral vascular blood flow conditions and thus diagnosis of cerebrovascular diseases.
Structural Features:
Kejin's Ultrasonic Transcranial Doppler Blood Flow Analyzer adopts modular design. It features compact size, light weight, and portability, and can be flexibly combined with external computer systems to achieve the detection functions of an ultrasonic transcranial Doppler blood flow analyzer.
Technical Characteristics:
The Ultrasonic Transcranial Doppler Blood Flow Analyzer has functions including blood flow spectrum display, blood flow velocity measurement and calculation, parameter adjustment, video playback, print report setup, etc. It can store, retrieve, and delete medical record data.
Ultrasound Probes:
Equipped with KJ-PW-2MHz ultrasound probe with measurement range not narrower than 20cm/s～200cm/s, enabling fixed-distance detection of intracranial cerebrovascular blood flow velocity.
Equipped with KJ-CW-4MHz ultrasound probe with measurement range not narrower than 10cm/s～100cm/s, enabling detection of extracranial superficial vascular blood flow velocity.
Blood Flow Direction:
When the arrow points upward, the blood flow spectrum displayed above the baseline is positive direction, below is reverse; when the arrow points downward, the blood flow spectrum displayed above the baseline is reverse direction, below is positive.
M-wave Window:
After clicking the button, a progress bar appears at the lower right corner of the interface, indicating automatic blood vessel search. This process automatically adjusts depth and freezes the spectrum when optimal conditions are reached.
Supports functions like emboli detection/trend chart/automatic vessel search/M-wave, etc.
Spectrum Playback:
After freezing the image, click the playback function key to replay the just-detected spectrum process. Click again to stop playback.
Data Backup and Recovery:
As more data accumulates in the TCD device, users may temporarily delete some data but wish to review it later. Users can use the data backup function to back up current user data to other hard disk partitions or storage devices.
If stored data is corrupted or lost, or if previously saved examinee data needs to be reviewed, users can use the data recovery function to restore data from the backup to the software installation location for viewing within the software.
