Cardiac ultrasound training model

Abstract

The invention relates to a cardiac ultrasound training model comprising a main model body being a model made of a simulated human heart. The main model body consists of a plurality of model assembliesand an acoustic window board assembly. The model assemblies are connected successively from the heart bottom of the main model body to the heat tip; the connection plane between each two adjacent model assemblies is a cardiac ultrasound standard section; and mirror image structures are formed at the connection parts. The acoustic window board assembly has a foldable sector structure; and the multiple model assemblies are connected with the acoustic window board assembly. According to the cardiac ultrasound training model, the main model body is based on the design of the simulated human heartand is formed by successive connection of multiple model assemblies; and with cooperation of adjustment by the acoustic window board assembly, the whole standard section is displayed, so that interpretation transformation from the cardiac anatomy to the ultrasonic image is realized conveniently. Therefore, students are assisted in understand the corresponding relationship of the ultrasound anatomy quickly and thus the teaching goal is achieved quickly. Moreover, the model has advantages of reasonable price, first-rate quality, high portability, high repeatability, and good economic efficiency.

Description

technical field [0001] The invention relates to the technical field of medical teaching models, in particular to a cardiac ultrasound training model. Background technique [0002] Emergency bedside ultrasound training has been widely promoted in China as an emerging project in recent years, and the demand has exploded. With the increase in the amount of training, the quality of training has attracted more and more attention. Bedside ultrasound training Among them, the technical mastery of cardiac color Doppler ultrasound has become a difficult point. Due to certain differences between ultrasound images and solid anatomy, there are certain challenges for students to operate independently in actual operation and in the future for image cognition and understanding. The traditional solid model of the heart is also often used in bedside ultrasound training, and it is often necessary to add pictures for further explanation in order to improve the training effect. The traditional ...

Problems solved by technology

However, when Sectra Table imports images, it needs to convert CT images into Sectra system anatomical images, which has high requirements for images, because echocardiography training requires images to be images of the circulatory system with enhanced development, including double images of venous phase and arterial phase, so Additional delayed imaging is required for the patient when acquiring images. This inspection sequence is not included in ordinary CT examination items, which not only increases the cost of image acquisition time and patient radiation dose; in the 3D images synthesized with CT-enhanced images, the system cannot The structure and position of the valve are shown well, but the standard echocardiographic view includes several views with the valve as the positioning structure, so it cannot be learned in this image; in addition, the Sectra Table system can only complete the teaching of anatomical cutting in its own machine, but The dissection table is very expensive, and the domestic price is extremely high, so it is difficult to be purchased by ordinary hospitals; in addition, the instrument is large in size and weight, and the display screen is easily damaged. Therefore, long-distance transportation is difficult to achieve, and it cannot meet the needs of a large number of clinical trainings across the country. needs
