Abstract

The invention relates to the biotomy field and in particular relates to a novel specimen conservation solution. The conservation solution is prepared from the following components: 1-5g of potassium sorbate, 0.1-1g of nano-silver, 100-300ml of ethyl alcohol, 1-20ml of glycerin and 10-20g of citric acid; the pH value of the conservation solution is kept to be 5-6, and water is added for making up to constant volume of 1000ml. The specimen conservation solution can effectively keep the original color and luster of a specimen, the softness of all muscular tissues and ligaments and good toughness and elasticity; no moldy phenomenon occurs to the liquid level and the wall of a conservation vat, exposed tissue caused by reduction of the conservation solution still has certain humidity, and no moldy corrosion phenomenon is caused; the conservation solution is transparent, has no pungent smell, has good sterilization and anti-mold properties, does not contain toxic and harmful substances, is an environment-friendly solution, and is beneficial to large-scale application.

Description

technical field [0001] The invention relates to the field of biological anatomy, in particular to a novel specimen preservation solution. Background technique [0002] Human anatomy is a highly intuitive morphological science, and its experimental teaching activities are inseparable from cadaver specimens. In anatomy courses, teachers mainly use specimens to teach and explain, and students learn by watching specimens. The human specimens used are free bulk specimens, which are mainly preserved with 10% formalin solution. Due to the low boiling point of formalin, it is very volatile at room temperature. As the temperature rises, the volatilization speed accelerates, emitting a strong pungent smell, which seriously pollutes the laboratory environment, making students resist contact with specimens and affecting experimental teaching. development of work. On the other hand, formalin is extremely harmful to the health of the human body. If the human skin is directly exposed to ...
