Title
(EN) IV FLUID DELIVERY SYSTEM
(FR) SYSTEME D'ADMINISTRATION D'UN FLUIDE PAR VOIE INTRAVEINEUSE
Abstract
(EN)
An IV pump (10) for delivering fluid through a resilient, deformable tube (30) to improve the accuracy, consistency, and predictability of flow through the tube, wherein a plurality of pinching fingers (18) occlude the tube against a flat portion of a pressure pad (28), and a plurality of pumping fingers (22) interspaced between said pinching fingers deform the tube (without occluding it) from different directions against a V-shaped portion (36) of the pressure pad (28) to pump the fluid downstream as well as to urge the tube to restore its cross-sectional area.
(FR)
Pompe d'administration d'un fluide par voie intraveineuse par l'intermédiaire d'un tube élastique déformable (30) assurant la précision, la régularité et la prévisibilité de l'écoulement dans le tube, cette pompe comportant plusieurs doigts d'étranglement (18) permettant de boucher le tube en le pressant contre la partie plate d'un patin (28), plusieurs doigts de pompage (22) intercalés entre les doigts d'étranglement et permettant de déformer le tube (sans le boucher) dans différentes directions en le pressant contre une partie en V (36) du patin (28) afin de pomper le fluide en aval et de solliciter le tube de façon qu'il retrouve sa surface de section originale.
