1 材料 (1)童尸:选用4～7岁的整具尸体,从股三角、颈部及臂部分别切开双侧股动脉、颈总动脉及肱动脉。然后根据全身血管行程及制作要求和目的插管。(2)填充剂:①低浓度填充剂:过氯乙烯10～15g,乙酸乙酯100ml,邻苯二甲酸二丁酯3ml,油画颜料适量。②高浓度填充剂:过氯乙烯20～25g,丙酮100ml,邻苯二甲酸二丁酯3ml,油画颜料适量。(3)自凝牙托粉50g,自凝牙托水50ml,邻苯二甲酸二丁酯18～22ml。(4)预制标本盒:根据尸体的大小预制好有机玻璃盒,内盛小量水。一俟标本插管后即移入盒内人,以后的标本灌注、腐蚀及冲洗过程均在此盒内进行。这样可避免标本受压及反复搬动而造成变形或断枝等,从而可有效地维持标本的整体形态。2 操作要点与体会 (1)插管与防腐固定根据待灌注的标本选用不同口径的插管。为了使全身血管铸型具有饱满
MATERIALS (1) Childhood Corpse: A 4-to-7-year-old corpse was selected. Bilateral femoral, common carotid, and brachial arteries were dissected from the triangle, neck and arm of the femur. Then according to systemic vascular stroke and production requirements and purposes intubation. (2) Filler: ① low concentrations of fillers: vinyl chloride 10 ~ 15g, ethyl acetate 100ml, dibutyl phthalate 3ml, oil paint amount. ② high concentrations of fillers: perchlorethylene 20 ~ 25g, acetone 100ml, dibutyl phthalate 3ml, oil paint amount. (3) self-condensate care powder 50g, self-condensate teeth care water 50ml, dibutyl phthalate 18 ~ 22ml. (4) prefabricated specimen box: According to the size of the prefabricated plexiglass box, filled with a small amount of water. Once the specimen is intubated into the box, the specimen will be filled, corroded and washed in this case. In this way, the specimen can be prevented from being deformed or broken due to being pressed and repeatedly moved, thereby effectively maintaining the overall shape of the specimen. 2 points and experience of operation (1) intubation and preservation of fixed according to the specimens to be perfusion selected different diameter cannula. In order to make systemic vascular cast full
