Abstract

Patente de Invenção: <B>"SISTEMA MEDICINAL DE TRANSFERêNCIA DE LìQUIDO COM UMA MANGUEIRA DE TRANSFERêNCIA E UMA BOMBA DE MANGUEIRA PARA BOMBEAR LìQUIDOS"<D>. O sistema medicinal de transferência de líquidos possui uma mangueira de transferência (10). Um segmento desta mangueira de transferência (10) forma a mengueira de bomba (16) de uma bomba de mangueira (17). A bomba de mangueira (17) é executada como bomba axial, que movimenta axialmente duas áreas distanciadas da mangueira de bomba (16) uma em relação à outra. A bomba de mangueira (17) possui ainda elementos de vedação (V1, V2) que comprimem alternadamente as áreas de espremer da mangueira de bomba. Com o sistema de transferência de líquidos é obtida uma alta precisão de dosagem. Uma vez que a mangueira de bomba não é espremida, as perdas de calcar são baixas e a bomba de mangueira possui um alto grau de rendimento.Invention Patent: <B> "MEDICINAL LIQUID TRANSFER SYSTEM WITH A TRANSFER HOSE AND A HOSE PUMP FOR PUMPING LIQUIDS" <D>. The medical liquid transfer system has a transfer hose (10). A segment of this transfer hose (10) forms the pump hose (16) of a hose pump (17). The hose pump (17) is performed as an axial pump, which axially moves two areas spaced apart from the pump hose (16) in relation to each other. The hose pump (17) also has sealing elements (V1, V2) that alternately compress the squeezing areas of the pump hose. With the liquid transfer system, high dosing accuracy is achieved. Since the pump hose is not squeezed, the pressure losses are low and the hose pump has a high degree of efficiency.
