Abstract

Se describe una jeringa que tiene un barril (20) y un embolo (38) dispuesto deslizantemente dentro del barril. Un extremo distante del barril define un techo y una punta alargada, en comunicacion fluida con el barril, se extiende desde el techo. Una protuberancia (56) que forma un resalto es dispuesta sobre uno del techo del barril y la cabeza del embolo. Cuando la cabeza del embolo se pone en contacto con el techo, la protuberancia forma un canal entre la cabeza del embolo y el techo. El canal aisla el fluido dentro del canal desde la punta alargada, que a su vez reduce la atomizacion del fluido a traves del extremo distante de la jeringa. En otra modalidad, para reducir la atomizacion del fluido a traves del extremo distante de la jeringa se puede usar un sistema de reduccion de impulso para reducir o impedir que la porcion proxima aplique un impulso dirigido distantemente a la porcion distante despues que se rompe la conexion rompible.
