Method for preparing teaching specimen of apical four-chamber view of fetus suffered from congenital heart disease

Abstract

The invention relates to a method for preparing a teaching specimen of an apical four-chamber view of a fetus suffered from a congenital heart disease. The method comprises the following steps: selecting an artificial labored fetus having a malformed heart; antiseptically treating the artificial labored fetus to prepare a free heart specimen, and making the vertical axis of the view parallel to the long axis of the heart and making the horizontal axis of the view parallel to the left-right direction of the heart from the apex of the heart,; and along the direction from the front upper position of 1 to 2 centimeters of left and right edges of the heart to the base of the heart, cutting the heart from the center of the right atrium and a position nearby an orifice of a pulmonary vein of the left atrium. The obtained apical four-chamber view specimen has the advantages of integrated and complete structures of all parts, no damage to microstructures in the heart, the same shape as that in a real living body, and capability of meeting the requirements of medical teaching and practice and the like, and is suitable for schools, hospitals or medical research institutes.

Description

technical field [0001] The invention relates to a method for preparing a teaching sample, in particular to a method for preparing a teaching sample for a fetal congenital heart disease apical four-chamber section. Background technique [0002] According to reports, children with congenital heart disease account for 8% to 12% of babies born in my country, which means that 120,000 to 200,000 children with congenital heart disease are born in my country every year. About 20% of children with congenital heart disease have no therapeutic effect or die early after birth. Bring endless pain. Ultrasonography is almost the only option for prenatal imaging diagnosis of fetal cardiac malformations. Therefore, carrying out fetal heart ultrasound examination is an important part of prenatal ultrasound monitoring and predicting fetal health. It is in line with my country's national policy of improving the quality of birth population and reducing low-age mortality. [0003] Fetal cardiac ...

Problems solved by technology

[0004] Although most sonographers now have a good foundation in ultrasound medicine and years of experience in ultrasound diagnosis, the basic theory of ultrasound diagnosis of the fetal heart is relatively weak, and they lack understanding of the standardized section and anatomical structure of the fetal heart. Unclear and blind examination, the apical four-chamber view can reflect the special structure of the heart with tricuspid atresia, Ebstein anomaly, ventricular dysplasia and single-ventricular congenital heart disease, so fetal congenital heart disease with apical four-chamber The teaching specimens of the heart section can intuitively reflect the special structure of the heart of tricuspid atresia, Ebstein deformity, ventricular dysplasia and single ventricle congenital heart disease, providing reference for teaching and research
