Ultrasonic probe device

Abstract

The invention discloses an ultrasonic probe device. The device comprises an ultrasonic probe, a card cover, pressure sensors A, B, an amplifier, an A / D (analogue-to-digital) converter, a radio frequency emitter, a signal processor, a radio frequency receiver and a display, and a power source; the pressure sensors at two sides of the ultrasonic probe can sense the pressure on the probe and human body checked surface in real time; the amplifier is used for amplifying the signal output by the sensor, the A / D converter can convert the analogue signal into a corresponding digital signal; the radio frequency emitter, the signal processor and the radio frequency receiver are used for transmitting the signal, and computing a final partial pressure value at two ends and a total pressure value received by the whole checking surface; and the display is used for displaying the pressure values at two sides and the total pressure value in real time. The ultrasonic probe device can observe the pressure size applied by the probe in the checking process in real time, and provides a quantitative criterion for the elastic imaging of the ultrasound, and has a certain clinical significance for judging lesion character and property.

Description

technical field [0001] The invention relates to an ultrasonic probe device, which belongs to the technical field of medical instruments. Background technique [0002] In clinical work, color Doppler imaging technology and spectral Doppler, as a non-invasive ultrasound examination method, are considered to be very important technologies for screening high-risk groups such as cardiovascular disease and abdominal organ disease, and have been widely used In the detection of various systems of the whole body. At the same time, ultrasonography is currently the most effective and convenient method for fetal examination during pregnancy, and has been widely developed and applied clinically. In particular, the monitoring and quantification of the amniotic fluid volume of pregnant women in each period of pregnancy is more important. Studies have shown that the amniotic fluid volume and accurate measurement directly affect the growth of the fetus in the womb. Therefore, color Doppler...

AI Technical Summary

Problems solved by technology

At present, in the actual operation process, doctors often perceive the magnitude of pressure through feeling and experience, but such inspections lack quantification and low sensitivity. The main shortcomings are as follows:

[0004] First, in clinical work, elastography research often lacks quantitative consideration of the applied pressure, thus causing differences in diagnostic results to a certain extent

[0005] Secondly, for beginners, the pressure exerted by the hand directly affects the quality of the image, which further affects the measurement of anatomical structures and lesion tissues
