Zusammenfassung:The invention relates to an injection head (10), for injecting a fluid substance, and a syringe comprising such a head, said head being characterized in that it has a connection body (11) continued by a hollow tube (15) intended to communicate with the outlet of the reservoir and having a distal end, and a needle (16) having a pointed distal end, the head additionally comprising means for controlling the relative movement of said needle (16) with respect to said hollow tube (15) between a puncturing position, in which the pointed end of the needle (16), which is extendable in the hollow tube (15), protrudes from the distal end of the hollow tube (15), and a position for monitoring and characterizing the liquid coming from the injection site, the pointed distal end of the needle (16) being set back from the distal end of the hollow tube (15) in said position. La invención se refiere a un cabezal de inyección (10), para inyectar una sustancia líquida, y una jeringa que comprende dicho cabezal, el cabezal se caracteriza porque tiene un cuerpo de conexión (11) continuado por un tubo hueco (15) destinado a comunicarse con la salida del depósito y que tiene un extremo distal, y una aguja (16) que tiene un extremo distal puntiagudo, el cabezal comprende adicionalmente medios para controlar el movimiento relativo de la aguja (16) con respecto al tubo hueco (15) entre una posición de punción, en la que el extremo distal puntiagudo de la aguja (16), que se puede extender en el tubo hueco (15), sobresale del extremo distal del tubo hueco (15), y una posición para monitorear y caracterizar el líquido que viene del sitio de inyección, el extremo distal puntiagudo de la aguja (16) retrocede desde el extremo distal del tubo hueco (15) en la posición.
