Description

The blood vessel survey meter

Technical field

This utility model relates to the blood vessel positioner in the medical care precess, relates in particular to carry out a blood vessel survey meter that other blood vessel is surveyed before the dark venous duct implantation surgery.

Background technology

In hemodialysis, internal jugular vein conduit implantation surgery is a common technical operation, in order to set up quick and easy vascular access.Adult's internal jugular vein has 5%～10% anatomical variation, and the vital tissue internal organs such as carotid artery, vagus nerve, trachea are arranged near the operative region, has certain difficulty in the operating process, and common have complication such as hematoma, oozing of blood, blood drainage are smooth, puncture failure.For patient fat, the cervical region tubbiness, blood vessel may be in desired location or angiostenosis, and blind wearing can be increased the weight of operation risk, and the carotid artery of wearing parallel trend such as mistake can cause massive hemorrhage, hemorrhagic shock.What therefore, how to improve success rate of operation, complication is the focus that surgical doctor is paid close attention to.At present, some scholars advises guiding descending conduit implantation in the color doppler ultrasonography instrument, but because the sterilization of color ultrasound indoor sanitation fails to reach the operative region requirement, can not carry out operation technique, and hand propelled color ultrasound instrument is expensive, and need professional image personnel operation, fail extensively in clinical position, to promote.Become kidney internal medicine field problem demanding prompt solution so seek a kind of other blood vessel positioner of economical and practical bed by the surgical doctor operation.

Summary of the invention

This utility model purpose is to provide a kind of accurate positioning, cheap blood vessel survey meter.

For achieving the above object, this utility model can be taked following technical proposals:

Blood vessel survey meter described in the utility model, it comprises the information gathering box that is connected with mobile phone or laptop computer communication, described information gathering box is M mould disposable plates and the dual pathways quadrature demodulator that is connected with its communication, and the power output end of described mobile phone or laptop computer is electrically connected with described M mould disposable plates by transformator; Described dual pathways quadrature demodulator is connected with the communication of 4MHz probe.

Described dual pathways quadrature demodulator comprises the clock signal driver module that is electrically connected with the signal output part of described M mould disposable plates, and the signal output part of described clock signal driver module is electrically connected with the signal input part of M mould disposable plates by emission door module, emission amplification module, inverting model, reception amplification module, adjustment module and amplification module; Described inverting model is connected with the sampling volume module communication, and described sampling volume module is connected with the communication of described 4MHz probe.

This utility model advantage is accurate positioning, cheap, practical convenient.In the other mode of being taked the manual probe scanning by surgical doctor of operation table, surveying the position at patient's body surface moves, process through the blood flow spectrum analyzer system, obtain a series of 3-D views of arranging in order, input to mobile phone or laptop computer, can position detection to blood vessel in real time, to assist dark vein catheterization operation safety, successfully to carry out, improve widely the success rate of operation.Because it is easy to use, it is light and handy, cheap to carry, ten thousand yuan of cost less thaies can be directly inputted into patient vessel's ultrasonic image in mobile phone or the laptop computer, and can set up the corresponding data library storage, are convenient to arrangement and analytical information, are easier to use at basic hospital.In use in real time blood vessel is positioned detection, and image stabilization, for surgical doctor provides a great convenience, can be used as the front routine examination of vascular puncture operation in patients and in clinical position, apply.

The specific embodiment

As shown in Figure 1, 2, 3, blood vessel survey meter described in the utility model, it comprises the information gathering box 2 that is connected with mobile phone or laptop computer 1 communication, described information gathering box 2 is M mould disposable plates and the dual pathways quadrature demodulator that is connected with its communication, and the power output end of described mobile phone or laptop computer 1 is electrically connected with described M mould disposable plates by transformator; Described dual pathways quadrature demodulator is connected with the communication of 4MHz probe; Described dual pathways quadrature demodulator comprises the clock signal driver module that is electrically connected with the signal output part of described M mould disposable plates, and the signal output part of described clock signal driver module is electrically connected with the signal input part of M mould disposable plates by emission door module, emission amplification module, inverting model, reception amplification module, adjustment module and amplification module; Described inverting model is connected with the sampling volume module communication, and described sampling volume module is connected with the communication of described 4MHz probe.

Its operation principle is: in operating process, coat couplant at the 4MHz detecting head surface, the skin of probe being close to detection window, use the continuous wave (CW) of 4MHZ, probe detection degree of depth 15-30mm, selecting 2mm is that the advanced degree of depth is detected blood vessel, position and the angle of slight mobile probe, probe is launched ultrasound wave towards operative region, because erythrocytic diameter is less than hyperacoustic wavelength in the blood, erythrocyte plays scattering process to ultrasound wave, part ultrasonic reflections is returned the 4MHz probe, the 4MHz probe receives echo can be converted to the Doppler frequency shift value blood flow rate (unit is cm/s) automatically by information gathering box 2, observes blood flow rate, blood flow direction, Flow spectrum features etc. are in input information notebook computer or mobile phone.M mould disposable plates is the precision instrument company limited manufacturing of Shenzhen reason nation, main settling signal control, the filtering to signal after the demodulation, sampling, the function such as communicate by letter with mobile phone or laptop computer 1.Dual pathways quadrature demodulator is finished the conversion of the signal of telecommunication and ultrasonic energy signal by probe, receives Work Incentive signal and mode of operation control signal from M mould disposable plates, the Doppler signal after the output demodulation.Dual pathways quadrature demodulator is finished the output of synchronous demodulation, filtering and the Doppler signal of ultrasound emission driving, the place ahead reception, analogue signal under the control of M mould disposable plates.With the Doppler frequency spectrum transform analysis, calculating also shows such as a series of physiological parameter indexs such as average speed of blood stream, drag indexs, provides the operator with important informations such as puncture vessel position and vascular conditions, guides it to carry out correct operation technique path.In actual applications, it is information gathering box 2 that dual pathways quadrature demodulator and M mould disposable plates are integrated into a system integration module, carries convenient.
