Description
Technical field:
The present invention relates to a kind of adjusting and fixing device of ultrasonic inspection probe for alliteration beam carotid artery, belong to the biomedical engineering technology field.
Background technology:
Common carotid artery is the tremulous pulse trunk of cervical region, and left and right sides is respectively from aortic arch and brachiocephalic trunk.This tremulous pulse is at the sternoclavicular joint rear, and is up in the both sides of trachea and larynx.Whole end is divided into internal carotid artery and external carotid artery, and just differing in the position of bifurcated, is positioned near the thyroid cartilage upper limb.The part of expanding of common carotid artery crotch and internal carotid artery initial part is called carotid sinus again, and carotid atheroma is generally good to be sent out in this.Ultrasonic Doppler technique is crucial method of obtaining cardio-cerebrovascular hemodynamics information in the present medical supersonic diagnostic field.The ultrasonic beam of cells such as the erythrocyte that moves in blood vessel reflection has formed doppler ultrasonic blood flow signal.Because blood flow has pulsating nature in the blood vessel, the Doppler frequency shift in the doppler blood flow signal and the speed of blood flow have proportionate relationship, include abundant blood flow information.The method that intactly shows these information is made analysis of spectrum to signal exactly, represents the signal spectrum composition over time with time-frequency distributions.On the one hand, real-time Doppler frequency shift is used to estimate blood flow rate, and the intensity of Doppler signal is used for ultrasound angiography; On the other hand, the parameter and the blood flow state that calculate from time frequency distribution map have certain relation, and these information are for medically non-invasive diagnosis and evaluation angiopathy have crucial meaning.The colour that grows up the eighties, frequency spectrum and power doppler technology combine with two-dimensional ultrasound, can be accurately, noinvasive, Real-time and Dynamic, repeatable vascular morphology and the hemodynamics information of showing.
Domestic and international research is thought: carotid artery atherosclerosis plaques is a risk factor for isehemic stroke.Speckle makes and causes blood flow disorder by the blood vessel local stenosis.Accurately detect endovascular blood flow characteristic, particularly near the small turbulent condition of lumen wall, can effectively improve to the early diagnosis of disease and to the objective evaluation of therapeutic outcome, this just means needs accurate separating blood vessel wall beat signal and blood flow signal in ultrasonic carotid artery testing process, separate that tube wall is beaten and blood flow signal in, as far as possible intactly preserve low speed (also comprising at a high speed) blood flow signal composition, thereby improve the sensitivity of clinical diagnosis.Studies show that, use alliteration bundle ultrasound detection, one of them acoustic beam perpendicular to blood vessel wall to measure the blood vessel wall signal of beating, another acoustic beam and blood vessel (blood flow direction) acutangulate to obtain and comprise the blood flow signal that tube wall is beaten, the combining adaptive filtering technique can obtain the separation accuracy of blood vessel signal and blood flow signal more accurately.This just requires in testing process, and the tester need operate and adjust two ultrasonic probes simultaneously, and not only difficulty is big, and reliability and stability also are difficult to guarantee.
Through the file retrieval, do not find the adjusting and fixing device of ultrasonic inspection probe for alliteration beam carotid artery relevant open report identical with technical solution of the present invention.
Summary of the invention:
The object of the present invention is to provide a kind of probe of alliteration beam carotid artery ultrasound detection to regulate fixture, this device helps using two ultrasonic probes that carotid artery is done the detection of alliteration bundle, has the direction energy independent regulation of each acoustic beam, the advantage that adjusting range is big, easy and simple to handle, stability is high.
The probe of alliteration beam carotid artery ultrasound detection of the present invention is regulated fixture and is comprised the neck ring base that is made of two parallel elastic metal wires (1), run in the guide the probe fixed mount (2) that neck ring base one side can horizontally slip on the metal wire up and down, place two universal joints (5) that can regulate the sound beam direction of each probe arbitrarily on the probe fixed mount (2), the probe that places universal joint (5) is folder hole (3) fixedly, place the fixedly clip (4) on the folder hole (3) of probe, place the two ends of metal wire (1) to be used to regulate the buckle (6) and the draw-in groove (7) of neck ring internal diameter size, place the button (8) on the groove card (7).
Employed material and part are all bought from the market among the present invention.
Apparatus of the present invention are used two ultrasonic probes that carotid artery is made the alliteration bundle and are detected, and have the direction energy independent regulation of each acoustic beam, the advantage that adjusting range is big, easy and simple to handle, stability is high.
Description of drawings:
Fig. 1 is the structural representation of facing of adjusting and fixing device of ultrasonic inspection probe for alliteration beam carotid artery.
Fig. 2 is the side-looking structural representation of adjusting and fixing device of ultrasonic inspection probe for alliteration beam carotid artery.
The specific embodiment:
The probe of alliteration beam carotid artery ultrasound detection of the present invention is regulated fixture and is comprised the neck ring base that is made of two parallel elastic metal wires 1, run in the guide the probe fixed mount 2 that neck ring base one side can horizontally slip on the metal wire up and down, place two universal joints 5 that can regulate the sound beam direction of each probe arbitrarily on the probe fixed mount 2, the probe that places universal joint 5 is folder hole 3 fixedly, place the fixedly clip 4 on the folder hole 3 of probe, place the two ends of metal wire 1 to be used to regulate the buckle 6 and the draw-in groove 7 of neck ring internal diameter size, place the button 8 on the draw-in groove 7.Employed material and part are all bought from the market among the present invention.
In the test, tested object is got after fully having a rest and is sat or dorsal position, is coated with an amount of ultrasonic coupling agent in detecting the position.Press the button 8 on the lower bayonet slot 7, withdraw from the buckle 6 in the draw-in groove 7, will launch the neck ring base and enclose and be enclosed within the tested object cervical region, adjust the position of buckle 6 in draw-in groove 7 and make the internal diameter size of neck ring be fit to the experimenter.The probe fixed mount 2 that slides is to the carotid artery position of detecting.Press lower catch hoop 4 respectively, ultrasonic probe is inserted fixedly folder hole 3, and the up-down adjustment probe is to suitable position.Regulate the sound beam direction of each probe by universal joint 5, one of them acoustic beam perpendicular to blood vessel wall to measure the blood vessel wall signal (high frequency blood flow signal complete obiteration this moment) of beating, another acoustic beam and blood vessel (blood flow direction) acutangulate the blood flow signal (existing high frequency low amplitude value blood flow signal in the signal has the high amplitude tube wall of low frequency signal again) that comprises tube wall and beat to obtain.
Practical application shows that the present invention meets design requirement fully.
