用人体内脏解剖标本作教具,能使学生准确地掌握内脏各器官的自然形状和位置。我用8—9月的胎儿作内脏的解剖材料。将材料洗净,放平展直,从左到右,从上到下地将胎儿标本的胸腔内的心脏和肺腹腔内的肝脏、胃、大肠、小肠和膀胱以及膈肌等器官全部露出。并在其头部、上臂和下肢等处肌肉或器官较多的部位,注入5％的酒精。再将此胎儿标本平放全部浸泡入95％的酒精溶液中,固定一段时问(3—5天)后,用纱布在固定液中再次洗净内脏各器官和体表,取出标本晾干,贴上各器官的标笺,用一块与胎儿标本等长等宽的玻璃片,放在标本背面,用线把胎儿标本的头、手和脚等部位固定在玻璃片上。然后把它正面装入标本缸(可用玻板、角钢等材料自制),
With human anatomy specimens as teaching aids, students can accurately grasp the internal organs of the natural shape and location. I use the fetus from August to September as visceral anatomical material. The material is washed, flattened straight, from left to right, from top to bottom will be fetal specimens of the heart and the lung cavity of the lungs of the liver, stomach, intestine, small intestine and bladder and diaphragm and other organs exposed. And in its head, upper arm and lower limbs and other parts of the muscle or organs more, inject 5% alcohol. Then the fetal specimens were all soaked into 95% alcohol solution for a fixed period of time (3-5 days), with gauze in the fixed fluid again washed organs and surface organs, remove the specimens to dry, Affixed to the various organs of the paper, with a piece of fetal specimen length equal to the width of the glass, on the back of the specimen, the line with the fetal specimen head, hands and feet and other parts fixed on the glass. Then put it into the specimen cylinder positive (available glass board, angle steel and other materials made)
