Definitions

  • the present invention introduces an improved suction catheter of the dual-lumen type to minimize and to alleviate the above-mentioned problems of vent-lumen blockage and gastric reflux by providing the suction catheter with a plurality of vent apertures spaced apart longitudinally from the open distal end of the suction lumen by a distance sufficient to assure that at least one of the vent apertures will be positioned above the level of the contents to be withdrawn from the organ of the patient.
  • stomach of the patient upon completion of the suction process and while the patient remains in intensive care or recovery. If, for any reason, there is a build-up of fluids within the stomach, either by feeding or from bleeding, or from normal gastric fluids, during this period, the possibility of gastric reflux by a sudden compression force upon

Abstract

L'invention concerne un cathéter d'aspiration à deux lumières (11) qui est constitué d'un tube pliable (12) s'étendant longitudinalement présentant des lumières séparées (13, 14) et indépendantes d'aspiration et de mise à l'air. L'extrémité proximale (15) du cathéter présente une première extrémité ouverte (13) pour la lumière d'aspiration et une seconde extrémité séparée ouverte (14) pour la lumière de mise à l'air. Le cathéter présente une ouverture au niveau de son extrémité distale à travers laquelle s'écoulent les fluides à retirer de l'organe d'un patient vers la lumière d'aspiration. Une pluralité d'ouvertures espacées (17) ménagées dans la partie distale du cathéter s'étendent de la lumière d'extrémité à travers la paroi du tube pliable vers la surface extérieure du cathéter. Les ouvertures sont placées longitudinalement espacées entre elles et de la pointe distale du cathéter. La pluralité d'ouvertures sont indépendantes et à une distance de la lumière d'aspiration.
