M250 Ultrasound Transcranial Doppler System

M250 Ultrasound Transcranial Doppler System

The M250 Ultrasound Transcranial Doppler Flow Analyzer is a cost-effective single-channel, four-depth TCD instrument. This product not only has all the functions of the M250 TCD instrument, but also has the switching function of three interfaces of single depth, double depth and four depth. It can simultaneously observe the blood flow spectrum of multiple blood vessels to diagnose the cerebral vascular stenosis. Has great value. The M250 TCD instrument has advanced M-mode and automatic search function, which can quickly find blood vessels and greatly improve the diagnostic efficiency. The M250 TCD is equipped with 2MHz and 4MHz probes for intracranial vascular testing and extracranial vascular testing.

Functional characteristics

1. Powerful parameter database

Memory clinical data of large-scale hospital vascular parameters. The measured value can be compared with the reference value in real time, and the abnormal data is alarmed. Built-in standard reference blood flow spectrum map, easy for operators to switch at any time, comparative analysis.

2. Embolization (HITS) detection technology

The unique embolic detection technology, when the embolus (HITS) appears, the signal shows the transition waveform, and can be played back for identification, which is convenient for doctors to observe and diagnose.

3. Multi-depth dynamic M-mode technology

The advanced M-mode function can display multiple blood flow signals at different depths at the same time, and quickly locate the optimal blood flow depth to help doctors obtain the best blood flow spectrum map.

4. Professional trend graph technology

Clearly display the macroscopic changes of the four-parameter measurement curve of Vp, Vd, Vm, and HR, and accurately judge whether the blood flow velocity is stable.

5. Vascular automatic search function

Kejin's original automatic blood vessel search technology captures weak signals, quickly locates blood vessels, greatly shortens the time to locate blood vessels, and reduces the technical dependence of the operator's higher techniques.

6. Multiple depth free switching

It can realize single-depth/double-depth/four-depth free switching, and display blood flow spectrum images of multiple depths of the same blood vessel in real time. It is of great value in the diagnosis of cerebral vascular stenosis, which greatly improves the diagnostic accuracy of cerebrovascular diseases.

7. High sensitivity probe technology

With a composite high-sensitivity probe, the detection sensitivity is greatly improved, and the signal-to-noise ratio is significantly enhanced. The probe interface uses a metal push-pull self-locking connector, the connection is more reliable, the appearance is more refined, and the anti-interference ability is greatly improved.

8. Flexible report editing

Built-in multiple report formats provide great convenience for doctors to write, edit and recall spectrum and data. There are also parameter comparison display modes, and the diagnosis results are clear at a glance.

9. Other technologies:

1)Dynamic, static envelope, real-time display of the spectrum, calculation of blood flow parameters.

2)A variety of reports are optional and easy to modify.

3)Watch any medical record at any time, store the blood flow spectrum of the blood vessels for movie playback.

10. Clinical application:

1)Examination of cerebrovascular diseases. Such as: hypertension and cerebral arteriosclerosis, cerebral vascular stenosis and occlusion, cerebral vasospasm, headache and migraine, intracranial arteriovenous malformation, subclavian stealing and other diseases diagnosis, disease development observation, guiding drug treatment, estimation Prognosis and so on.

2)Evaluation of cerebral vascular function: evaluation of preoperative and postoperative cerebral vascular surgery; hemodynamic evaluation of cerebral vascular composite operation; screening of patients for cerebral angiography and selection of contrast timing.

3)Monitoring of critically ill patients: monitoring of cerebral blood flow before, during and after surgery of cerebrovascular patients; cerebrovascular monitoring of critically ill patients;

4)Preventive health care: routine physical examination of middle-aged and elderly people, epidemiological investigation of cerebrovascular disease, establishment of files and prediction of stroke in high-risk groups of cerebrovascular disease.

5)Detection of microthrombus.

6)Other basic research: research on the evolution process, pathogenesis and etiology control of cerebrovascular diseases; the effects of drugs on cerebral blood vessels and cerebral blood flow; cerebral blood flow under different conditions.
