Abstract

The invention discloses specimen preservation fluid good in preservation effect and a preparation method of the specimen preservation fluid. The preservation fluid is mainly prepared from 50% glutaraldehyde, polyoxyethylene aliphatic alcohol ether, industrial alcohol, benzalkonium bromide, phenol, glycerinum, ethylenediamine tetraacetic acid disodium salt and water. The prepared preservation fluid is free of formaldehyde, slow in volatilization, free of pungent gas, quite low in toxicity, high in safety, good in preservation effect and capable of making a specimen good in color and luster, preventing the specimen from mildew after long-term preservation and making the specimen soft in texture.

Description

technical field [0001] The invention relates to a specimen preservation liquid with good preservation effect and a preparation method thereof, in particular to a specimen preservation liquid with good preservation effect and a preparation method thereof. technical background [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 preservation solution. [0003] Existing preservation solution is mainly formalin preservation solution, and formalin solution injection in the blood vessel of human body can prevent the corruption of corpse. The specimen preservation solution with good preservation effect of formalin has a good fixation effect, which is due to the large amount of formaldehyde comb...
