摘要 |
A roller pump conduit defining a pump chamber is provided. The roller pump conduit includes a roller contact portion having a fill region and a delivery region. The fill region has a first taper configured to determine volume delivery per revolution of a roller head. The delivery region has a pressure region having a second taper and a discharge region having a third taper. The third taper has a lesser degree of taper than the second taper. The delivery region is configured to produce a pulsatile flow out of the conduit. Furthermore, a roller pump having a roller pump conduit is provided. The roller pump conduit of the roller pump has a fill region and a delivery region, the fill region having a first taper, and the delivery region having a second and third taper, wherein the third taper has lesser degree of taper than the second taper. |
