Abstract

Le problème décrit par la présente invention est de fournir un instrument hémostatique permettant d'arrêter efficacement le saignement à un site de ponction sans exercer une pression excessive sur un vaisseau sanguin et à l'aide d'une simple opération. La solution selon l'invention porte sur un instrument hémostatique 100 qui comprend : un élément de capuchon 110 configuré de façon à être disposé au niveau d'un site de perforation p formé dans un bras supérieur A d'un patient ; et un élément d'opération 120 configuré de façon à appliquer une force de traction à l'élément de capuchon 110. L'élément d'opération comprend : un élément de poignée 121 ; et un élément de liaison 123 qui relie l'élément de poignée 121 et l'élément de capuchon 110.
