Embodiment 1

[0036] Example 1: as figure 1 As shown, a method for combining plasticized specimens and embedded specimens to produce display specimens includes the following production steps:

[0037] 1) a method for making a display specimen in combination with an embedded specimen and a plasticized specimen, is characterized in that: comprise the following production steps:

[0038] 1) Material selection: select complete, no trauma, no fracture, no diseased human specimens;

[0039] 2) Preservation treatment: The specimen is perfused with 15% formalin, and the formalin is infiltrated into various parts of the specimen through large blood vessels (femoral artery, common carotid artery), and finally placed in 8% formalin. Soak in the preservation solution for 3 months for use;

[0040] 3) Freezing: Preserved human specimens are placed in a freezer at -20°C for 7 days according to the normal anatomical posture;

[0041] 4) Sawing: make a midsagittal incision along the eyebrows, navel, ext...

Embodiment 2

[0055] A method for producing a display specimen by combining a plasticized specimen and an embedded specimen, comprising the following production steps:

[0056] 1) Material selection: select complete, no trauma, no fracture, no diseased human specimens;

[0057] 2) Preservative treatment: The specimen is perfused with 20% formalin, and the formalin is infiltrated into various parts of the specimen through large blood vessels (femoral artery, common carotid artery), and finally placed in 12% formalin. Soak in the preservation solution for 3 months for use;

[0058] 3) Freezing: Preserved human specimens are placed in a freezer at -20°C for 10 days according to the normal anatomical posture;

[0059] 4) Sawing: make a midsagittal incision along the eyebrows, navel, external urethra, occipital carina, and spinous process of the frozen human specimen in step 3); A total of 12 slices are sawed, and the left and right sides are sawed until the femoral head can be displayed, and ...

Abstract

The invention relates to a method for manufacturing a display specimen by combining a plasticized specimen and an embedded specimen, which comprises the following steps of: sawing a frozen human body specimen according to specific lines to obtain a fault specimen, and performing dehydration and degreasing, vacuum impregnation, embedding, curing and the like on the fault specimen to obtain an embedded fault specimen. And in addition, dissecting the saw-cut residual specimen to remove tissues such as muscles and nerves, displaying a normal femoral head, and performing bleaching, dehydration and degreasing, vacuum impregnation, curing and the like to obtain a plasticized specimen. And finally, the embedded specimen and the plasticized specimen are fixedly combined, so that not only can the real anatomical structure of the specimen be visually seen, but also the hierarchical structure of the sawed section can be seen, reliable basis and scheme are provided for clinical medicine, the operation and the use are simple, and teaching of teachers and learning of students are facilitated.

Description

technical field [0001] The invention relates to the field of display specimens, in particular to a method for preparing a display specimen by combining a plasticized specimen and an embedded specimen. Background technique [0002] At present, the commonly used biological specimens for teaching and learning in schools include: plasticized specimens, model specimens and dipped bottled specimens that open the spinal canal from the back to reveal the spinal cord. [0003] Plasticized specimen technology has been applied to the field of biological anatomy specimens for nearly 20 years. The biological plasticized specimens produced by plasticization technology are non-toxic, tasteless, can be stored for a long time, easy to use, and can be stored in the air for a long time. Specimens can only visually see the anatomical structure, but cannot see the hierarchical structure of the sawed section. Separate tomography embedding can only see the hierarchical structure of the section, an...
