Method for preparing fetal congenital heart disease aortic arch long-axis section teaching specimen

Abstract

The invention relates to a method for preparing fetal congenital heart disease aortic arch long-axis section teaching specimen. The method comprises the following steps: adopting an artificial labored stillbirth of which the heart is subject to developmental deformity, carrying out antiseptic treatment on the artificial labored fetus, preparing into a dissociative heart specimen, cutting the aortic arch from the top of the aortic arch, enabling the transverse axis of the section to be parallel to the long axis of the aortic arch, and enabling the longitudinal axis bearing to point to the upper wall of the left atrium. The obtained aortic arch long-axis section specimen has the advantages of unbroken and complete structures of all the parts, no damage to micro structures inside the heart, a shape which is the same as that of a real living body and the like, can well meet the medical teaching and practice requirements, and is applicable to schools, hospitals or medical research organizations.

Description

technical field [0001] The invention relates to a method for preparing a teaching specimen, in particular to a method for preparing a teaching specimen for fetal congenital heart disease aortic arch long-axis 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 card...

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. In the blind inspection with unclear content, the long-axis view of the aortic arch can reflect the special heart structure of congenital heart disease with coarctation or disconnection of the aorta, so the teaching specimen of the long-axis view of the aortic arch for fetal congenital heart disease can intuitively reflect The special structure of the heart in congenital heart disease with coarctation or disconnection of the aorta, providing reference for teaching and research
