Portable ultrasonic diagnostic device

Abstract

The invention discloses a portable ultrasonic diagnostic apparatus which comprises a main frame, a CRT kinescope, a CRT drive plate, a power panel, a mainboard and a probe plate. The CRT kinescope and the CRT drive plate are installed on the main frame. The power panel is arranged at one side of the main frame vertically. The mainboard and the probe plate are arranged at the other side of the main frame vertically. As the proposal is adopted, a mainboard and probe plate component is apart from the power panel in space, thereby reducing space radiation coupling and improving image output quality. The mainboard and probe plate component and the power panel are arranged symmetrically and are as close as possible in weight, thereby ensuring the gravity center of a whole machine is balanced. The mainboard and the probe plate are connected from board to plate instead of cable, and the mainboard and the probe plate are piled up and shielded, thereby ensuring a compact structure and also avoiding the mutual interference between the mainboard and the probe plate and the interference caused by the connection by a long cable. The whole machine has compact and stable structure, strong anti-interference capacity and good image quality.

Description

【Technical field】 [0001] The invention relates to a structure of a portable ultrasonic diagnostic instrument. 【Background technique】 [0002] Ultrasound imaging is a non-invasive and cheap medical imaging diagnostic method, which is widely used in the examination of various parts of the body, such as the examination of abdominal organs and obstetrics and gynecology. With the rapid development of electronic technology and the improvement of integration, ultrasonic diagnostic systems are becoming more and more miniaturized for portability. However, integrating complex ultrasound systems in a compact space, interference and heat dissipation have brought challenges to the architecture of the whole machine. As a portable ultrasonic diagnostic system, compact and light structure is the basic requirement, but the compact structure brings the problem of interference; the analog echo signal of ultrasound is often amplified hundreds or even thousands of times, so The problem of inte...

AI Technical Summary

Problems solved by technology

In this existing architecture, the power board and the probe board are relatively close in space, making it difficult to completely eliminate the interference of the power board to the probe board, and the analog echo of the probe board is very sensitive to interference; the connecting cable between the main board and the probe board is long , across the main frame, power supply board and CRT driver board, the signal is easy to be interfered; the above will cause the image quality to degrade

In addition, because the power board is relatively heavy, the power board and the probe board are placed on one side, and the main board is on the opposite side, which will cause the center of gravity of the machine to be biased to one side of the power board.
