People who are bad at drawing can't become painters, people who are bad at playing musical instruments can't become musicians, and people who are bad at sports can't become athletes. Strangely enough, even people who are clumsy with their hands can become surgeons, and what is often overlooked is that, unlike art and sports, surgeons directly affect people's lives and bodies. [Solution] Just like abacus classes, piano classes, English classes, calligraphy classes, and swimming classes, if surgical classes were established and children practiced surgical procedures using cadavers such as pigs from a young age, they would already be surgical masters by the time they are around 20 years old, the age when ordinary medical students first pick up a scalpel.

This invention relates to the field of medical research based on cadaver specimens, specifically disclosing a method for arterial perfusion of veins from cadaver specimens based on ink and an automated arteriovenous differential colorimetric perfusion reagent. The perfusion reagent includes ink and a base perfusion solution, wherein the base perfusion solution is a latex, gelatin solution, or other base perfusion solution that can pass through the capillary network and does not affect the color-changing effect of the ink.
