Product Introduction
Working Principle:
The ultrasonic transcranial Doppler blood flow analyzer utilizes the principle of ultrasonic Doppler frequency shift to explore and measure non-fetal blood flow movement information. It is used for blood flow measurement in transcranial, cervical, and peripheral blood vessels, excluding analytical diagnostic functions.
TCD technology uses ultrasound to penetrate weak areas of the skull and, combined with the Doppler principle, performs real-time spectral analysis of Doppler frequency shift echo signals from red blood cells in blood vessels. This enables the analysis of cerebrovascular blood flow conditions, thereby facilitating the diagnosis of cerebrovascular issues.
Structural Features:
The Kejin ultrasonic transcranial Doppler blood flow analyzer adopts a modular design. It is compact, lightweight, and portable, and can be flexibly combined with external computer systems to achieve the detection functions of an ultrasonic transcranial Doppler blood flow instrument.
Technical Features:
The ultrasonic transcranial Doppler blood flow analyzer features blood flow spectrum display, blood flow velocity measurement and calculation, parameter adjustment, video playback, and print report settings. It can store, retrieve, and delete patient records.
Ultrasonic Probes:
Equipped with a KJ-PW-2MHz ultrasonic probe with a measurement range not narrower than 500px/s to 5000px/s, enabling fixed-distance detection of intracranial cerebrovascular blood flow velocity.
Equipped with a KJ-CW-4MHz ultrasonic probe with a measurement range not narrower than 250px/s to 2500px/s, enabling detection of extracranial superficial blood vessel flow velocity.
Blood Flow Direction:
When the arrow points upward, the blood flow spectrum displayed above the baseline is forward, and below is reverse. When the arrow points downward, the blood flow spectrum displayed above the baseline is reverse, and below is forward.
Spectrum Playback:
After freezing the image, click the playback function key to replay the recent detection process. Click again to stop playback.
M-Wave Window:
After clicking the button, a progress bar appears in the lower right corner of the interface, indicating automatic blood vessel search. This process automatically adjusts the depth and freezes the spectrum when optimal conditions are reached.
Data Backup and Recovery:
As data stored in the TCD instrument accumulates, users may temporarily delete some data but wish to review it later. In such cases, users can use the data backup function to back up current user data to other partitions of the hard drive or other 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, enabling review within the software.
