Embodiment Construction

[0027] The present invention will be further described below in conjunction with the accompanying drawings and embodiments.

[0028] Method of the present invention is:

[0029] (1) Collect fresh embryo specimens, that is, collect embryo specimens that develop normally within 24 hours of death from the mother.

[0030] (2) Organize, measure, determine the gestational age of the collected specimens and put them into groups containing 75% ethanol for storage. The specific method is: the gestational age is calculated according to the sitting height (CR) in the calculation chart of Chris and Tekam. Every two weeks is a group, divided into 17 groups, counting from 5-38 weeks; while measuring the sitting height of the embryo, the specimen is fixed: the collected fresh embryo specimens are cleaned and sorted, and the length of the top buttocks (ie sitting height) is measured and grouped. Fix for one week in 75% ethanol fixative. Then put it into 95% ethanol fixative solution for 3...

Abstract

The invention relates to a method for producing transparent embryo specimen, wherein it comprises that (1), collecting fresh embryo specimen; (2), fixing the specimen; (3), poaching; (4), dewatering; (5), colorizing; (4), dewatering with glycerin and making it transparent.

Description

technical field [0001] The invention relates to a method for making a human body specimen transparent, in particular to a method for making a fetal transparent specimen. Background technique [0002] Making transparent specimens is to use some chemicals or physical methods to treat body tissues so that their refractive index is similar to that of transparent agents or the surrounding medium, so that the growth and development of fetal bones can be clearly observed through muscle tissue. This method can display structures that are difficult to observe clearly by general anatomical methods, such as incompletely ossified fetal bones, etc., and this method minimizes damage to soft tissues. But at present, because the bones of fetal specimens are not yet fully developed, the transparent method of adult specimens cannot be fully applied to the transparent production of fetal specimens, and the production time is long, and the effect of fetal transparent specimens is not good, whic...
