Abstract

Die Erfindung betrifft eine mechanisch betriebene Flüssigkeitspumpe (1), insbesondere für medizinische und ernährungsphysiologische Flüssigkeiten. Sie weist einen Rahmen (2) zur Aufnahme einer Blattfeder (5), die zwischen zwei Schnappstellungen beweglich ist, auf. Es ist ferner eine im Rahmen gehaltene elastische Membran (15) und ein zwischen die Blattfeder und die Membran eingelegter Beutel (8) zur Aufnahme der Flüssigkeit vorgesehen. Der Beutel weist einen Abgang (10) für die Flüssigkeit auf. In der auf die Membran zu bewegten einen Schnappstellung der Blattfeder wirkt diese auf den Beutel, bei Druckerhöhung der in diesem befindlichen Flüssigkeit, ein und es wird die elastische Membran durch den Beutel in eine gedehnte Stellung überführt. Eine solche Pumpe ist baulich einfach gestaltet und besonders preisgünstig herzustellen. Sie kann einfach gehandhabt werden und ist universell einsetzbar.
