ABSTRACT:
Dispensing device for dispensing small quantities of fluid comprising a compressible balloon with an end-to-end capillary inserted within the walls of the balloon in such a way that the one end of the capillary communicates with the interior of the balloon and the other end of the capillary communicates with the exterior space. The balloon has at least one opening through which the interior space of the balloon communicates with the exterior space. The at least one opening has a flow resistance that is designed so that a fluid contained in the capillary is expelled when the balloon is compressed. The present invention also comprises a system and method for the metered dispensing of fluids.
