Abstract

Un cathéter à ballonnet ayant de multiples canaux et de multiples ballonnets pour arrêter rapidement un saignement dans des vaisseaux sanguins, comprenant : un canal de fil-guide/fluide (6) s'étendant dans la direction axiale du cathéter à ballonnet ayant de multiples canaux et de multiples ballonnets pour arrêter rapidement un saignement dans des vaisseaux sanguins; de multiples ballonnets (21-25) agencés séquentiellement et connectés de manière fermée au cathéter à ballonnet ayant de multiples canaux et de multiples ballonnets pour arrêter rapidement un saignement dans des vaisseaux sanguins; de multiples canaux de ballonnet (1-5) qui s'étendent dans la direction axiale du cathéter à ballonnet ayant de multiples canaux et de multiples ballonnets pour arrêter rapidement le saignement dans les vaisseaux sanguins et qui sont en communication un à un avec les ballonnets (21-25). Dans chaque ballonnet, le cathéter à ballonnet ayant de multiples canaux et de multiples ballonnets pour arrêter rapidement un saignement dans des vaisseaux sanguins est pourvu d'un marqueur (31-35) pour une détection in vitro. Le cathéter à ballonnet ayant de multiples canaux et de multiples ballonnets pour arrêter rapidement un saignement dans des vaisseaux sanguins peut être rapidement inséré dans une ou plusieurs parties de saignement de corps sur le site de plaie sans l'aide d'une technologie de positionnement par fluoroscopie compliquée, et peut maintenir l'alimentation en sang d'organes vitaux tout en fermant avec précision les taches de saignement afin d'arrêter le saignement. Ledit cathéter à ballonnet présente une amélioration significative par rapport aux cathéters à ballonnet d'arrêt de saignement sans pression existants.
