Abstract

L'invention concerne un appareil (10) et un procédé de distribution d'un liquide, tel qu'un analgésique à administrer à un patient. L'appareil (10) comprend un réservoir (12) rempli d'un analgésique et connecté, au moyen d'une douchette (26), à des moyens d'administration, tels qu'une aiguille ou canule. La douchette (26) comprend des soupapes d'admission (14) et d'évacuation (22), ainsi qu'une structure de recul élastique et poreuse (18). L'analgésique s'écoule à partir du réservoir (12) à travers la soupape d'admission dans les pores de la structure de recul (18) et s'écoule de la structure de recul (18) à travers la soupape d'évacuation (22) à administrer au patient. Celui-ci peut comprimer la structure de recul (18) de manière à administrer une grande dose de l'analgésique quand la structure de recul (18) est relâchée, la nature de recul de celle-ci aspirant le liquide du réservoir (12) dans les pores et remplissant ceux-ci. Ce flux est limité de manière à ne pas dépasser une vitesse maximale prédéterminée.
