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 measurements in transcranial, cervical, and peripheral vessels, excluding analytical detection functions.
TCD technology employs 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 within blood vessels. This enables the analysis of cerebrovascular blood flow conditions, thereby facilitating the detection of cerebrovascular diseases.
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 Characteristics:
The ultrasonic transcranial Doppler blood flow analyzer features functions such as blood flow spectrum display, blood flow velocity measurement and calculation, parameter adjustment, cine playback, and print report settings. It can store, retrieve, and delete medical record data.
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 vascular blood flow velocity.
Blood Flow Direction:
When the arrow points upward, the blood flow spectrum displayed above the baseline indicates forward direction, while below indicates reverse direction. When the arrow points downward, the blood flow spectrum above the baseline indicates reverse direction, while below indicates forward direction.
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.
Spectrum Playback:
After the image is frozen, clicking the playback function key replays the recent detection process. Clicking again stops the playback.
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 utilize 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.
