Abstract

Una bomba de infusion (10) incluye un deposito (18) que contiene un líquido terapéutico para llevar a cabo una infusion. El deposito (18) incluye unasalida (36) para el líquido. Una bomba de aire volumétrica (24) se encuentra operativamente asociadacon el deposito (18) para presurizar el deposito y deeste modo impulsar el líquido a través de la salida (36). Una válvula (12) se encuentra operativamente asociada con la salida (36) e impide el flujo de líquidoa través de la salida hasta que seobt iene una presion umbral selecta en la salida. Subsecuentemente la válvula asegura una abertura en la salida que mantienela presion en el deposito (18) en substancialmente la presion umbral selecta, por medio de la cual el caudal volumétrico através de la salida (36) esproporcional al caudal volumétrico de aire de la bomba de aire volumétrica (24). La válvula (12) varía la abertura en la salida para mantener la presionselecta. La salida preferentemente consiste de un conducto flexible(36) que p resenta un área de la seccion transversal interna no deformada selecta y laválvula (12) variablemente restringe el flujo de líquido a través de la salida prensando un segmento del conducto para variar el área de la secciontransversalinterna del segm ento del conducto. Un método de llevar a cabo una infusion de líquido terapéutico a un paciente incluye proveer un deposito (18) que contieneun líquido terapéutico, proveer una bomba de aire volumétrica (24) parapresurizar el deposito para impulsar líquido fuera del deposito a través de una salida(36) y mantener una presion selecta en el deposito de modo tal que el líquido a través de la salida de líquido es proporcional al caudal volumétrico de labomba deaire volumétrica.
