Problems solved by technology

However, there are also obvious deficiencies in the actual application process: 1) formaldehyde has a strong pungent smell, and formaldehyde can cause damage to multiple organs and systems.
2) Seriously affect the teaching effect
3) Seriously pollute the air environment and water environment
At present, in order to improve the teaching environment, many units have adopted powerful exhaust equipment, which only transfers the pollution to the atmosphere; if the treatment of formaldehyde wastewater requires expensive facilities, some units even directly discharge the wastewater into the sewer
4) It is difficult to control the concentration of mildew
The anti-mildew liquid is volatile, and it will polymerize when exposed to air for a long time, and precipitate white paraformaldehyde or paraformaldehyde. In serious cases, the whole bottle of formalin will turn into a white paste, which wil

Abstract

The invention discloses a composition for preserving corpse samples, and relates to corrosion prevention, rot resistance and preservation of corpses in medical teaching and scientific work. The composition comprises rot-proof and mold-proof active component, infiltration modifier and wetting agent, wherein the rot-proof and mold-proof active component is diacetate; the infiltration modifier is one or a mixture of two or more than two of nitrate, sulfate or hydrochloride according to any proportion; and the wetting agent is polylol. The invention also provides a method for preparing the composition for preserving the corpse samples. The method is special for preserving the corpse samples after setting treatment; the composition contains sodium diacetate, is used for preserving animal or human corpses, and can effectively solve the problems of corrosion prevention, rot resistance and preservation of the corpses; and the preservation liquid has the characteristics of long rot resistance time, good effect, no formaldehyde, safety and non-toxicity, easily obtained raw materials, and low price.

Description

technical field [0001] The invention relates to a composition for anti-mold, anti-corrosion and preservation of corpses in medical teaching and scientific research and a preparation method thereof. technical background [0002] For a long time, anatomy laboratories in medical colleges have been using formalin solution as the soaking solution for wet preservation of corpse specimens, and its main component is formaldehyde. Formaldehyde solution has the advantages of strong fixation and hardening effect on tissues, good permeability, low price, and good bactericidal and antiseptic effects. However, there are also obvious deficiencies in the actual application process: 1) formaldehyde has a strong pungent smell, and formaldehyde can cause damage to multiple organs and systems. . Formaldehyde seriously endangers the health of people exposed to it. 2) Seriously affect the teaching effect. The irritating smell of formaldehyde can irritate the mucous membrane of the respiratory...
