Abstract
A new pulsatile pump is described, and the results of bench tests and animal experiments are presented. The arterial blood pressure and flow waveforms generated by the pump resemble those produced by the canine heart. The present pump is satisfactory for dog perfusions, and should, with minor modifications, be suitable for use in human surgery.
Zusammenfassung
Eine neue Pulsationspumpe wird beschrieben und die Ergebnisse von Labortests und Tierexperimenten mitgetilt. Der arterielle Druck und der Durchflussverlauf, der von der Pumpe erzeugt wird, ähneln denen vom Hundeherzen erzeugten. Die jetzigen Pumpen sind zufriedenstellend für Hundeperfusionen und sollten sich mit kleinen Änderungen für den Gebrauch in der menschlichen Chirugie eignen.
Sommaire
Cet article décrit une nouvelle pompe pulsative et donne les résultats des tests de laboratoire et des expériences conduites sur les animaux. La pression artérielle et les formes d'ondes du débit de la circulation engendrées par cette pompe ressemblent à celle sproduites parle coeur d'un chien. Cette pompe donne des résultats satisfaisants pour les perfusions menées sur les chiens et devraient convenir, après quelques légères modifications, à la chirurgie humaine.
