Preservative and its preparation method

Abstract

The invention relates to the technical field of biological and medical antisepsis, in particular to a preservative composition for animal or human corpses and specimens and its preparation and use methods. The disclosed preservative consists of 1%-10% main metal salt, 0.3%-2.5% citric acid, 1%-2.5% urotropine, 2%-5% auxiliary metal salt and 80% by weight. %-95% water composition. The main metal salt refers to iron salt, zinc salt and aluminum salt, and the auxiliary metal salt is sodium salt, potassium salt and calcium salt. It is a preservative with no irritating smell and strong anti-mold effect. It is used for anti-corrosion fixation and anti-corrosion preservation of human or animal corpses.

Description

technical field [0001] The invention relates to the technical field of biological and medical antisepsis, in particular to a preservative composition for animal or human corpses and specimens and its preparation and use methods. Background technique [0002] After the death of an animal or human, if the corpse is not treated with embalming, tissue autolysis and corruption will soon occur, which is manifested by softening or liquefaction of various organs, structural disintegration, and cell fragmentation. At the same time, a variety of amines, indole, methyl indole, hydrogen sulfide and other toxic products with strong odor are produced. The root cause of corpse corruption is the decomposition of enzymes. There are two main sources of these powerful biologically active enzymes: one is present in the lysosome of the body's own cells; the other is produced by continuously multiplying bacteria. Since the chemical essence of enzymes is protein, all kinds of physical and chemic...

Problems solved by technology

The use of formaldehyde for anti-corrosion has many advantages, but it also has the following serious defects: First, the tissue is hard and brittle after being treated with formaldehyde solution, with low toughness and elasticity, and is easy to break due to pulling during use; Or the dead body is stored under the condition of humid air, and mildew will occur soon; the third is to emit a strong suffocating and irritating smell, which has a strong stimulating effect on the eyes and respiratory tract mucous membranes, causing serious air pollution; the fourth is the toxicity of formaldehyde Its harm to the human body is manifested in three major aspects: stimulation, organ damage, and carcinogenesis.

However, these solutions have poor anticorrosion and fixation effects on corpses, and can only be used for immersion preservation of corpses that have undergone anticorrosion and fixation treatment, and cannot be used for anticorrosion and fixation of corpses.
