Problems solved by technology

However, formaldehyde is extremely volatile and has a strong pungent smell, which can cause damage to various organs of the human body, and will stimulate the conjunctiva and respiratory mucosa of the exposed personnel, resulting in reactions such as eye stinging, tearing, and dizziness. Difficult to use
Patent CN1086658A discloses a preservation solution formed by benzoate, ethanol, potassium nitrate and glycerol. First, benzoate and potassium nitrate are dissolved in tap water. It is made by adding ethanol and glycerol and stirring evenly, but benzoic acid is slightly soluble in water. If it is directly dissolved in water, it is not easy to dissolve and the efficiency is low

Abstract

The invention discloses human body teaching specimen preserving fluid and a preparing method thereof. The human body teaching specimen preserving fluid is prepared by mixing a solution A and a solution B, the solution A is prepared from 100-200 ml of industrial alcohol, 1-3 g of benzoic acid and 0.5-1.5 ml of essence, and the solution B is prepared from 5-15 ml of glycerol and 10-20 g of potassium nitrate, and water is added to set the volume to be 1000 ml. The teaching specimen preserving fluid is free of methanal and pungent smell of methanal and has the advantages of being good in sterilization and disinfection effect, free of peculiar smell and high in preparation efficiency.

Description

technical field [0001] The invention relates to the technical field of human body specimen preservation in medical teaching and scientific research, in particular to a human body teaching specimen preservation solution and a preparation method thereof. Background technique [0002] Teaching specimens refer to the specimens that students directly touch and study with their hands in the experiment. It is intuitive and clear, which is conducive to students' learning. Good anatomical exposure of teaching specimens is the key, but more important is storage. [0003] At present, aqueous formaldehyde solution (formalin) is widely used in the preservation of human specimens. Formalin has a strong penetrating ability and can combine with amino groups in proteins to coagulate the proteins and has a good antiseptic effect. However, formaldehyde is extremely volatile and has a strong pungent smell, which can cause damage to various organs of the human body, and will stimulate the conjun...
