Abstract

Un subsistema de dedos de bombeo para una bomba de infusiòn peristàltica tiene una carcasa, un miembro de pinza un miembro de bloqueo, y por lo menos un resorte de polarizaciòn. La carcasa incluye una ranura transversal, una primera pared lateral, y un segundo lado abierto a travès del cual el miembro de pinza y el resorte de polarizaciòn se insertan en la ranura transversal. El miembro de bloque incluye una porciòn de pie y una porciòn de pared lateral. La porciòn del pie es insertable en la cubierta a travès del segundo lado abierto, de manera tal que el miembro del bloque se restringe contra el movimiento relativo a la cubierta y la porciòn de la pared lateral del miembro del bloque se opone a la primera pared lateral de la cubierta, con lo cual el miembro de pinza se apoya en ambos lados laterales para prevenir la inclinaciòn del miembro de pinza.
