Abstract

Se describe una jeringa de seguridad. La jeringa incluye un cilindro de jeringa, un brazo movil, una aguja, un collar de aguja y una varilla impulsora. En uno de sus extremos, la varilla impulsora está unida al collar de aguja mientras que el otro extremo sobresale ligeramente en el borde de la aguja del cilindro de la jeringa. Cuando la inyeccion es administrada al paciente, el brazo movil recorre todo el camino hasta el borde de la aguja del cilindro de la jeringa. El brazo movil toca la varilla impulsora lo cual causa que el collar cubra automáticamente la punta de la aguja conforme la inyeccion es aplicada.
