过去制作血管腐蚀标本多采用赛璐珞、天然橡胶或喷漆等灌注血管,然后用浓盐酸腐蚀。由于灌注的物质粘度大,凝结后收缩率高和不够坚韧,致细小的血管分支不易显出,做出的标本亦容易折断或粘连变质,而且由于所有组织均被盐酸腐蚀,因此在标本上不能看到血管和骨骼的关系,影响了血管准确位置 In the past the production of vascular corrosion specimens and more use of celluloid, natural rubber or spray perfusion vessels, and then use concentrated hydrochloric acid corrosion. Due to the high viscosity of the material being infused, the high rate of shrinkage after coagulation and the lack of tenacity, the small blood vessel branches are not easily visible and the specimens made are also prone to breakage or adhesions, and since all tissues are corroded by hydrochloric acid, See the relationship between blood vessels and bones, affecting the exact location of blood vessels
