Description
POMPE ROTATIVE A BOUDINS TANGENTIELS
COEUR ARTIFICIEL AERIEN
Cette invention représente une pompe rotative, à boudins tangentiels, à pression constante; appropriée à la fonction d'un coeur artificiel; dont le caractère essentiel demeure en ce qu'elle agit sur deux conduits élastiques parallèles ; (n,l) remplissant le rôle de cylindres.ROTARY PUMP WITH TANGENTIAL RODS
AERIAL ARTIFICIAL HEART
This invention represents a rotary pump, with tangential tubes, at constant pressure; suitable for the function of an artificial heart; whose essential character remains in that it acts on two parallel elastic conduits; (n, l) fulfilling the role of cylinders.
La circulation artificielle du sang, envisagée à titre permanent; donc; sans système de filtrage ni usage indéfini d'anticoagulant, ne se heurte pas seulement à des problèmes mécaniques; mais aussi à l'incompatibilité que le sang manifeste à l'égard des metériaux artificiels; que meme le recours aux produits hémocompatibles, ne peut totalement résoudre (coagulation, pannus, hémolyse). The artificial circulation of the blood, considered on a permanent basis; so; without a filtering system or indefinite use of anticoagulant, it does not only come up against mechanical problems; but also to the incompatibility that the blood manifests with regard to artificial materials; that even the use of hemocompatible products, cannot totally resolve (coagulation, pannus, hemolysis).
La pompe tangentielle, sanglée sur la poitrine; est appelée, à résoudre ces problèmes; en entrant en action après que le sang ait été amené par dessus les côtes (h), sous la peau (o) ; au moyen de conduits autogreffés; reliant directement les veines, et artères en direction et en provenance des poumons. The tangential pump, strapped to the chest; is called upon to resolve these problems; by entering into action after the blood has been brought over the ribs (h), under the skin (o); by means of self-grafted conduits; directly connecting the veins and arteries to and from the lungs.
Les organes de compression sont formés de 3 rouleaux tronconiques (i) placés radialement à égale distance l'un de l'autre au bout d'un arbre actionné par un moteur électrique (e); dont l'axe se trouve à égale distance des deux conduits parallèles, contre lesquels il tourne; en créant des étranglements mobiles; de telle sorte que chaque rouleau sert de clop et de retenu à celui qui le précède; tout en exerçant son rale de piston, sur l'un et l'autre conduit de sens inverse. The compression members are formed of 3 frustoconical rollers (i) placed radially at equal distance from each other at the end of a shaft actuated by an electric motor (e); whose axis is equidistant from the two parallel conduits, against which it turns; by creating mobile throttles; so that each roll serves as a clop and a hold on the one preceding it; while exerting its piston ring, on one and the other conduit in opposite direction.
La figure 2 est proposée comme abrégé descriptif. Figure 2 is proposed as a descriptive abstract.
