Embodiment Construction

[0033] The following examples will further explain or illustrate the content of the present invention. However, the provided examples should not be construed as limiting the scope of protection of the present invention.

[0034] 1) Perfusion: After shaving the corpse, removing the dirt and oil stains on the skin, after disinfection, the corpse was shaped according to the anatomical posture with a bandage or plastic film, and the femoral artery was intubated to perfuse the fixative solution. 15% (weight ratio, the same below) formalin solution, which also has antiseptic effect. The amount of fixative perfused through the femoral artery of the cadaver should be sufficient. Generally, it is calculated according to the height and weight. The amount of 15% (weight ratio, the same below) formalin solution perfused is generally 10000-20000ml, which can make the tissue better fixed.

[0035] During this step, the blood, body fluids, secretions, etc. of the deceased will be directly ...

Abstract

The invention relates to an AIDS based preparation method of three-dimensional faulting specimens for researching and teaching. The preparation method is characterized by comprising the following steps: preparing the operation environment and operation conditions; shaping a corpse specimen of an AIDS patient, and pouring a formalin solution through femoral artery intubation for anticorrosion; after pouring the formalin solution into the corpse specimen, placing for 10-12 hours, and fully soaking the corpse in a formalin solution with the weight ratio of 5% for fixing for 6 months; positioning and scribing on the corpse specimen surface in the methyl violet elastic line method; placing the corpse specimen at the environment of -30 DEG C for freezing for 7-10 days; sawing the corpse specimen through a wood serrulate band saw for traverse, coronary and sagittal faulting specimens; conducting pathologic sampling on the faulting specimens; processing and preserving the specimens. The AIDS three-dimensional faulting specimens prepared through the preparation method realize the general perfect combination of the faulting specimens, CT images and pathological corroboration.

Description

technical field [0001] The invention relates to a preparation method of scientific research and teaching specimens, in particular to an AIDS-based scientific research and teaching specimen preparation method. Background technique [0002] AIDS, that is, acquired immunodeficiency syndrome (AIDS), is widespread in the world and has become a major problem that seriously threatens human health. In the early stage of Human Immunodeficiency Virus (HIV) infection, the cellular immune function declines mainly due to the replication of the virus and the destruction of the lymphocyte subsets T lymphocytes, such as CD4, CD8 and other immune cells. As the disease progresses to the AIDS stage, the function of the immune system is suppressed or lost, and patients are vulnerable to various opportunistic pathogenic pathogens to develop fatal opportunistic infections or tumors. Such as herpes simplex virus encephalitis, encephalitis caused by cytomegalovirus infection (CMV), tuberculosi...
