Abstract
The portable operational ultrasonic Doppler probe for detecting blood vessel in operation as one biomedical signal detector consists of casing, display and switches on the casing, and probe inside the casing. The flat probe ultrasonic piezoelectric ceramic element for emitting and receiving ultrasonic signal and conventional signal processing circuit connects to the ultrasonic piezoelectric ceramic element. The present invention has the advantages of simple structure, convenient use, etc. and may be used by surgeon in positioning organs and tissues and understanding the property of pathological changes in operation.
Description
Technical field:
The ultrasonic doppler blood vessel that the present invention relates to use in a kind of portable operation detects the probe of directed monitoring, belongs to the biomedical signals measuring device.
Background technology:
The instrument localization method of operation comprises the accurately method of measurement of guiding in real time that B ultrasonic imaging in the formation method (as B ultrasonic, CT, nuclear magnetic resonance, NMR, angiography CT etc.) and art before the art or doppler flow inaging survey.B ultrasonic imaging or doppler flow inaging are surveyed and can be helped each major organs of surgeon detailed inspection and tissue in the art, understand lesion nature, guarantee to perform the operation successfully.
Ultrasonic-B probe generally is to have particular geometric shapes in the operation, and the high-frequency linear array probe of the loculus that can be fit to health is arranged, T shape linearity commonly used, the finger curve and the linear probe of biplane.The doppler flow inaging survey meter is used flat probe always.
In the position of the special compactness in many positions, have only very little space can hold probe and examiner's hands.Because the restriction of probe lead wire may cause the probe rotation to depart from can not reach and detect the position.Can't understand needs to survey the position situation.
Up to now, do not find identical relevant open report with technical solution of the present invention.
Summary of the invention:
The objective of the invention is to overcome the prior art deficiency, and provide the ultrasonic doppler blood vessel that uses in a kind of portable operation to detect the probe of directed monitoring, this probe does not have lead-in wire, ultra sonic imaging or doppler flow inaging spectrogram are not provided, the qualitative indication of sound, light only is provided, be used for the performing the operation qualitative orientation of blood vessel of privileged sites is operation medium vessels " voltage test pencils ".
The present invention is achieved in that probe comprises measurement and demonstration.By placing display (1) and switch (2) on the shell, placing enclosure probe (3) to form, wherein probe (3) be a flat probe, is made of emission and the excess sound pressure electroceramics of reception ultrasonic signal, the signal processing circuit of the routine that is connected with the excess sound pressure electroceramics.Signal processing circuit comprises oscillating circuit, radiating circuit, signal receiving preamplifier, wave filter, signal demodulation, signal processing, one-chip computer and demonstration sounding and power supply.The excess sound pressure electroceramics is fixed on end in the shell with conventional method.
Advantages such as experience of the present invention has simple in structure, and is easy to use can help surgeon to check organ and tissue site in the art, understand lesion nature, carry out detecting orientation in the art, promote to perform the operation successfully.
Description of drawings:
Accompanying drawing 1 is a structural representation of the present invention.
Accompanying drawing 2 is a circuit block diagram of the present invention.
The specific embodiment:
Assemble the probe that the ultrasonic doppler blood vessel that uses in the portable operation detects directed monitoring according to a conventional method.During use, opening power, observation display is working properly.With the tested position of the directed alignment probe of ultrasonic doppler blood vessel of using in the portable art operation, probe is closely contacted with tested position subsequently, contact surface will keep wet.In the operating process, if any doppler echo, then have blood flow to flow near the explanation, display will show blood circumstance with flashing mode this moment, and velocity of blood flow is fast more, and flow is big more, and it is fast more to glimmer, and sound frequency is also high more simultaneously.Can learn thus and determine the blood vessel orientation.
Claims (1)
1, the ultrasonic doppler blood vessel that uses in a kind of portable operation detects the probe of directed monitoring, by placing display (1) and switch (2) on the shell, placing enclosure probe (3) to form, it is characterized in that probe (3) for flat probe, by emission and receive the excess sound pressure electroceramics of ultrasonic signal, the signal processing circuit of the routine that is connected with the excess sound pressure electroceramics constitutes.
