IPA: /ˈhiːməʊstæt/
KK: /ˈhiməˌstæt/
A tool used in surgery to stop bleeding by clamping a blood vessel.
The surgeon used a hemostat to control the bleeding during the operation.
Hemostat → It is formed from "hemo-" (from Greek "haima", meaning blood) and "stat" (from Greek "statos", meaning standing or stopping). The word "hemostat" refers to a device or agent that stops bleeding by standing in the way of blood flow.
Think of 'blood' ('hemo-') being 'stopped' ('stat') — that's what a hemostat does, it stops the flow of blood.
