A liquid delivery device which controls the flow of liquid from a liquid reservoir includes a resilient tubing having a wall with a substantially cylindrical cross section defining a flow lumen. The flow lumen is in fluid communication with the reservoir. A compression member selectively compresses a lengthwise segment of the cylindrical wall to collapse the flow lumen and releases the lengthwise segment to open the flow lumen. An elastomeric sleeve envelopes greater than half an outer diameter of the cylindrical cross section of the resilient tubing along at least a portion of the lengthwise segment of the cylindrical wall. The elastomeric sleeve biases the lengthwise segment of the resilient tube to restore it to its substantially cylindrical cross section when the compression member releases the lengthwise segment.
L'invention porte sur un système de délivrance de liquides provenant d'un réservoir comportant un tube élastique de section sensiblement cylindrique constituant une lumière pour le passage du liquide. Ladite lumière communique avec le réservoir. Un élément de compression comprime sélectivement dans le sens de la longueur un segment de la paroi cylindrique, ce qui écrase la lumière, puis libère le segment, ce qui ouvre la lumière. Un manchon d'élastomère enveloppe plus de la moitié du diamètre extérieur de la section transversale cylindrique du tube élastique et sur au moins une partie de la longueur du segment. Ledit manchon rappelle le segment de tube élastique vers sa forme cylindrique lorsque l'élément de compression libère le segment.
