Description
Technical Field
The utility model relates to a medical science teaching model technical field, concretely relates to foetus heart and great vessel supersound teaching mode.
Background
The first development of the fetus is the cardiovascular system, and the development of the heart of the fetus starts at the 2 nd week of pregnancy, namely the 2 nd week of pregnancy, and the original heart starts to sprout. The newly emerged heart is similar to a tube and is called as an original heart tube, the original heart tube gradually goes through the development processes of elongation, distortion, rotation, separation and the like until the atrial septum is formed in the 5 th week of pregnancy and until the ventricular septum is formed in the 8 th week of pregnancy, and therefore the development of the heart with four cavities is completed. After 6 weeks of gestation, the embryo rapidly grows and the fetal heart has begun to divide into ventricles and makes regular beats and begins to supply blood. The embryo is 0.6 cm in length, the cells divide rapidly, the primary kidney and heart nests have developed, the neural tube begins to connect the brain and spinal cord, and the primitive gut also begins to develop.
When a fetus is pregnant for 9-10 weeks, unique valves are formed at the outlets of the atria and ventricles, so that the blood can only flow along one direction without backflow. The blood circulation of the fetus is clearly separated from that of the mother. After the fetus enters 11 weeks of pregnancy, the body length of the fetus reaches 45-63 mm, the weight of the fetus reaches 14 g, and the sound of the rapid heartbeat of the fetus can be heard by means of a Doppler instrument. At 17 weeks of pregnancy, fetal heart development was almost complete with vigorous heart beats at about 145 beats/min.
