Embodiment 1

[0031] The preparation method of the animal bone plasticized specimen of the present embodiment comprises the following steps:

[0032] 1) Selection of materials: select vertebrate specimens with intact bones, no fractures, and no lesions. In this embodiment, ostrich specimens are selected.

[0033] 2) Antiseptic treatment, using 18% formalin to perfuse the ostrich specimen, the specific perfusion method is: through large blood vessels, including femoral artery, carotid artery, etc., formalin perfusion is permeated into various parts of the ostrich specimen, After the perfusion is completed, the ostrich specimen is soaked in formalin with a volume concentration of 10% for 3 months to obtain a preservative-treated ostrich specimen.

[0034] 3) dissecting, peeling off the skeleton of the ostrich specimen after antiseptic treatment from the ostrich specimen, the peeling method is: cut the skin of the ostrich specimen in the middle of the abdomen and peel it off completely, and pe...

Abstract

The invention relates to an animal skeleton plasticized specimen and a preparation method thereof and belongs to the technical field of biological plasticization. The preparation method of the animalskeleton plasticized specimen comprises the following steps: peeling off a skeleton of an animal specimen after preservative treatment from the animal specimen, maintaining cartilage and ligaments atjoint parts of the skeleton, and bleaching the peeled skeleton; soaking the peeled skeleton in an acetone solution for 50-60 days; leaving the skeleton specimen after dehydration and degreasing to stand still in silica gel in a vacuum pressure cabin for 40-50 days, adjusting the pressure of the vacuum pressure cabin to 0.8-1.2 kPa from 0.05-0.1 kPa gradually in standing, and extruding the silica gel into the skeleton specimen to replace the acetone solution; shaping and repairing the soaked skeleton specimen, putting into a curing tank, and curing by using silica gel curing agent steam, thereby obtaining the animal skeleton plasticized specimen. The animal skeleton plasticized specimen has a complete skeleton shape and structure without change, has a good three-dimensional feeling and is beneficial to later specimen observation.

Description

technical field [0001] The invention belongs to the technical field of biological plasticization, and in particular relates to a plasticized animal bone specimen and a preparation method thereof. Background technique [0002] At present, the commonly used biological specimens for teaching and learning in schools include: model specimens, boiled bone specimens, and naturally corroded bone specimens. The structure of the model specimen is simple, and there is a certain deviation between the teaching and the real specimen, which cannot show the real structure of the specimen. The production process of steamed bone specimens is simple, and the production process is not easy to control. The specimens are easily damaged, osteoporosis is easy, small bones are easy to be lost, and cartilage cannot be preserved. Grease is not easy to clean and easy to mold. It is easily damaged during use. Naturally eroded specimens are easily damaged, osteoporosis is easy, small bones are easy to...
