Etymology: Venipuncture is a compound built from two pieces: "ven-", from Latin "vena" meaning "vein," and "puncture," from Latin "punctura," a pricking or piercing, which itself comes from "pungere," to prick. The first element takes the form "ven-" here because English compounds of this kind link the Latin stem to the second part with a connecting vowel, so "veno-" plus "puncture" becomes "venipuncture" with an "-i-" in the middle instead of an "-o-." The result is a plain description of the procedure: a needle pricks a vein. Nothing in the word is metaphorical. Its parts keep their ordinary Latin senses, and the meaning of the whole is simply their sum, which is typical of the many medical terms English built from Latin and Greek building blocks.
