Embodiment 1

[0024] Embodiment 1: as figure 1 As shown, a method for staining blood vessels and nerves of human plastination specimens includes the following steps:

[0025] 1) Specimen preparation: select plasticized specimens that need to display blood vessels and nerve structures, and deformed ones. In this embodiment, plasticized specimens of the head and face are selected.

[0026] 2) Dyeing agent configuration: select the required pigment toner, mix the pigment toner with epoxy resin AB glue, the pigment toner is made of red, yellow and blue pigment toner made from natural ore, and use 300 sieves For screening and use, the ratio of pigment toner to epoxy resin AB glue is 3:1.5:0.8, and then add a small amount of absolute ethanol to dilute to adjust to a suitable color depth;

[0027] 3) Specimen pretreatment: apply xylene on the surface of blood vessels and nerves, remove the excess glue on the surface of blood vessels and nerves, and after the xylene volatilizes completely, carry o...

Embodiment 2

[0031] Embodiment 2: as figure 1 As shown, a method for staining blood vessels and nerves of human plastination specimens includes the following steps:

[0032] 1) Specimen preparation: select plasticized specimens that need to display blood vessels and nerve structures, and lose shape. In this embodiment, the plasticized specimens of the pelvis are selected;

[0033] 2) Dyeing agent configuration: select the required pigment toner, mix the pigment toner with epoxy resin AB glue, the pigment toner is made of red, yellow and blue pigment toner made from natural ore, and use 300 sieves For screening and use, the ratio of pigment toner to epoxy resin AB glue is 5:2.5:1, and then add a small amount of absolute ethanol to dilute to adjust to a suitable color depth;

[0034] 3) Specimen pretreatment: apply xylene on the surface of blood vessels and nerves, remove the excess glue on the surface of blood vessels and nerves, and after the xylene volatilizes completely, carry out oxida...

Embodiment 3

[0038] Embodiment 3: A method for staining blood vessels and nerves of human plastination specimens, comprising the following steps:

[0039] 1) Specimen preparation: select plasticized specimens that need to display blood vessels and nerve structures, and deformed ones. In this embodiment, plasticized specimens of the head and face are selected.

[0040] 2) Dyeing agent configuration: select the required pigment toner, mix the pigment toner with epoxy resin AB glue, the pigment toner is made of red, yellow and blue pigment toner made from natural ore, and use 300 sieves For screening and use, the ratio of pigment toner to epoxy resin AB glue is 6:3:1.2, and then add a small amount of absolute ethanol to dilute to adjust to a suitable color depth;

[0041] 3) Specimen pretreatment: apply xylene on the surface of blood vessels and nerves, remove excess glue on the surface of blood vessels and nerves, and wash with H 2 o 2 Oxidative bleaching, where H 2 o 2 is H at 3g / L 2 o...

Abstract

The invention relates to a dyeing method for human body plasticized specimen blood vessels and nerves, which belongs to the technical field of biological plasticization, and comprises the following steps: removing glue on the surface of a plasticized specimen which needs to display blood vessel and nerve structures and deformation through xylene, bleaching by using peroxide, adding ethanol into a mixed solution of pigment toner and epoxy resin AB glue for dilution, and after the mixed solution is adjusted to a proper color, respectively painting blood vessels and nerves; then curing in a vacuum pressure cabin; and finally, removing surface flooding through cleaning, and coating a layer of varnish, so that the dyed plasticized specimen is brighter in color, can be dampproof and wear-resistant, can be prevented from being oxidized, can be stored for a long time and is used for teaching observation.

Description

technical field [0001] The invention relates to the field of dyeing plasticized specimens, in particular to a method for dyeing blood vessels and nerves of human plasticized specimens. Background technique [0002] Biological specimens are animals or plants that are processed in whole or in part to maintain their original shape or characteristics, and are stored in the laboratories of scientific research institutions or schools for teaching, scientific research, or display and observation in biology and other disciplines. . At present, biological specimens commonly used in teaching and learning in schools include: model specimens, stripped specimens, and dipped and bottled specimens. [0003] The plasticized specimen technology has been applied to the field of biological anatomy specimens for nearly 20 years. The biologically plasticized specimens produced by the plasticized technology are non-toxic, tasteless, long-term preservation, easy to use, and can be stored in the a...
