CA 2142327
A system and method is provided which substantially eliminates the effect of air en- trapped in tubing (16) for delivering a liquid from a container (12). The inner diameter (d) of the tubing is selected such that the gravi- tational force of the liquid from the container (12) is greater than the surface tension of the liquid. A release agent may be used as a coat- ing layer (24) on the interior wall in addition to or alternatively from an expanded diameter.
L'invention concerne un système et un procédé pour éliminer substantiellement l'effet de l'air emprisonné dans un tube (16) pendant la transfusion d'un liquide à partir d'un contenant (12). Le diamètre interne (d) du tube est choisi de manière que la force de gravitation du liquide provenant du contenant (12) soit plus grande que la tension de surface du liquide. Comme agent de libération, on peut appliquer une couche de revêtement (24) sur la paroi interne du tube, et ce en complément du diamètre agrandi ou comme une alternative à celui-ci.
