Description
Technical field：
The invention discloses a kind of detection method of thrombus and its device, in particular to using blocked method detection thrombus method and
Device.
Background technology：
Thrombus is the fritter that blood flow is formed on the surface of cardiovascular system blood vessel inner face exfoliation or mend.
Thrombus detection mainly has two kinds of chemical examination and PE, and color doppler flow imaging instead of substantially at present
Phlebography, turn into the preferred inspection method of thrombus detection.It has the advantages that inspection operation is easy, noninvasive, inexpensive, and instrument
It is removable can be by bed or emergency ward inspection, diagnostic result are more reliable compared with phlebography.
Existing more report in thrombus ultrasound document.Although because of instrument, personal gimmick and each mechanism
Performance has some differences, but relatively unified.Vascular ultrasound is generally recommended with 5 ~ 7.5MHz linear array probes, dorsal position or
Semireclining position scanning, when above-mentioned position check still Bu can Que Ding popliteal vein the problem of when can use erect position or semireclining position.Ultrasound Instrument
Device regulation is appropriate make colorful blood full more plentiful and without ' overflow ', when Deep venou colorful blood can not clearly show that, Ying Shi
When the two peacekeeping colored hair radio frequency rates that reduce.
Even if in this way, for the thrombus of early stage, thrombus ultrasound shadow can not be still clearly showed that using ultrasonic examination
Picture, therefore, often need to be by means of householder method.At present, conventional householder method mainly has extrusion, uses the above method, though
Contribute to color doppler flow imaging, still, confirmed by putting into practice, thrombus breaks loose is likely to result in using extrusion simultaneously,
So as to further result in more serious consequence.

One charging portion, it is connected by pipeline with fixed part, fixed part is kept the shape tightened up or loosened by way of inflation
State；
One supersonic detection device, to carry out ultrasound detection to thrombus portion to be checked.
The second aspect of the present invention purpose is to provide a kind of detection method of thrombus, it is characterised in that using blocked method pair
Phlebothrombosis is detected, and specifically includes following steps：
（1）, by patient keep lateral position posture；
（2）, fixed part is fixed on to the centimeters of distal end 5~10 in thrombus portion to be checked；
（3）, by pressing/release charging portion, fixed part is kept deflation/relaxation state,
（4）, imaged for portion to be checked using supersonic detection device, while by adjusting charging portion, control the pressure of fixed part
Try hard to keep and hold 0.03~0.08MPA, prevent blood backflow, obtain ultrasonic image.
Further it is provided in：
The supersonic detection device is color doppler flow imaging instrument.
Using phlebothrombosis phlebothrombosis, right side gastrocnemius flesh above-mentioned detection method popliteal phlebothrombosis, left side flesh
Detected.
Fixed part is fixed on to the centimeters of distal end 5 in thrombus portion to be checked, to prevent blood backflow when carrying out ultrasonoscopy.
When carrying out ultrasonoscopy, the pressure of fixed part keeps 0.05~0.06MPA.
Beneficial effects of the present invention are as follows：
1st, detection method is compared with existing extrusion：
Security：For the present invention without extruding thrombi, effectively prevent extrusion causes the danger of thrombus breaks loose, peace
Full property is higher；
