Abstract

The rotatory pump with tangential flanges, in the form of an air-operated artificial heart, is composed of a compression and encapsulation member, formed by three frustoconical rollers i placed radially, equidistant from each other, at the end of a shaft actuated by an electric motor e, whose axis is situated equidistant from the two parallel vascular ducts, against which it rotates, creating moving constrictions, so that each roller serves as a non-return valve for the one which precedes it, whilst performing its role as a piston on both ducts, one of which injects the blood and the other extracts it from the lungs.

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.
