The VHK VENOUS HARDSHELL CARDIOTOMY RESERVOIR offers great capacity to fulfill all demands. Its compact design at a maximum capacity of 4200 ml is convincing. The upper venous inlet can be rotated through 360 degrees. Six symmetrically arranged suction connections ensure the reservoir is well positioned at the heart-lung machine. Venous blood and cardiotomy blood follow different routes through the reservoir. An integrated siphon at the end of the venous inlet prevents rising air. Minimal blood trauma and an outstanding air handling are two of the main characteristics of the reservoir. The reservoir is available in two versions: standard (VHK 2000) or vacuum tight (VHK 2001). The vacuum tight version incorporates a pressure relief valve.
