Definitions
- the present disclosure relates to the technical field of fluid control, and in particular, to a diversion control device.
- the main problem of patients with acute heart failure is the lack of blood supply and oxygen supply to various organs including the heart.
- the current clinical method of VA-ECMO combined with IABP can solve the problem of blood supply to the heart, it cannot improve the problem of oxygen supply to the heart.
- the deflection direction of the valve 21 can be controlled by the pulling cable 22.
- the pulling cable 22 can be positioned at the inner side of the tube wall 12 at the position opposite to the side hole 13, so that , through the pulling cable 22 , the movable end of the valve 21 can be deflected into the channel 11 to achieve the effect of blocking the channel 11 .
- FIG. 3 and FIG. 4 are schematic diagrams showing the state when the diversion control device is used for extracorporeal cardiopulmonary support. Please refer to FIG. 4 , one end of the catheter 1 is connected to a blood supply device in vitro, such as a membrane oxygenator, the other end of the catheter 1 is inserted from the subclavian artery 3, and enters other aortas after passing through the aorta of the heart.
- a blood supply device in vitro such as a membrane oxygenator

Abstract
L'invention concerne un dispositif de commande de guide d'écoulement, comprenant un cathéter (1) et un ensemble de commande (2), le cathéter (1) comprenant une paroi de cathéter (12), un canal (11) défini par la paroi du cathéter (12) et un trou latéral (13) disposé dans la paroi de cathéter (12). L'ensemble de commande (2) comprend une vanne (21), un élément élastique et un câble de traction ; un côté de raccordement de la soupape (21) est relié à un bord du trou latéral (13) au moyen de l'élément élastique et un côté mobile de la soupape (21) est relié au câble de traction. Lorsque le câble de traction est dans un état serré, le côté mobile de la soupape (21) est dévié vers l'intérieur vers le canal (11), de manière à bloquer au moins partiellement le canal (11) et augmente à son tour la quantité de fluide évacué par l'intermédiaire du trou latéral (13) ; et lorsque le câble de traction est dans un état relâché, l'élément élastique entraîne le côté mobile de la soupape (21) pour dévier vers le trou latéral (13), de façon à bloquer au moins partiellement le trou latéral (13) et à augmenter à son tour la quantité de fluide évacué par l'intermédiaire d'une sortie du canal (11). Le dispositif de commande de guide d'écoulement obtient l'effet technique d'ajustement d'une direction d'écoulement et d'un débit de fluide dans le cathéter (1) au moyen de la commande de l'ouverture et de la fermeture de la vanne (21).
