Abstract

Un mecanismo de bombeo de infusión incluye un motor, una pluralidad de dedos de bomba y una placa opuesta. Cada dedo de los dedos de bomba incluye una porción de cuerpo y una porción de cabeza. La porción de cabeza incluye una punta que está configurada para entrar en contacto con, y ocluir, un tubo instalado en el mecanismo de bombeo. La placa opuesta incluye un yunque con una pluralidad de concentradores de fuerza. Un concentrador de fuerza de la pluralidad de concentradores de fuerza corresponde a un dedo de bomba respectivo de la pluralidad de dedos de bomba. Además, el concentrador de fuerza incluye una superficie de concentración configurada para entrar en contacto con, y ocluir, el tubo. El concentrador de fuerza está alineado con una punta del dedo de bomba respectiva, de modo que a medida que el dedo se dirige hacia el tubo y entra en contacto con el tubo, tanto la punta como el concentrador de fuerza proporcionen presión a lados opuestos del tubo y al menos ocluyan parcialmente el tubo.
