An improved perfusion control assembly comprising a console and an oxygenator flanked by at least two flanking units, wherein a first flanking unit is a pump assembly and additional flanking units are at least one of additional pump assemblies, a display monitor, a parameter monitoring assembly, or a controller, is described. The improved assembly can have the advantages of a reduced extracorporeal blood volumes in cardiopulmonary and cardioplegia circuits, and improved ergonomics for the perfusionist. In a preferred embodiment, the elongated console of the assembly is divided into a central and at least two peripheral segments connected by hinged joints. The perfusionist may rotate segments to create a cockpit shaped assembly.

A method and apparatus for preventing accidental manual rotor reversal in a peristaltic pump is provided. A peristaltic pump may be provided with a hand crank or the like to drive a rotor assembly of the pump manually in the event of failure of the electric motor drive of the pump. An indicator may provide information to the pump operator to inform the operator of the direction in which the pump was rotating when last driven by the electric motor. Further an alarm device may alert the operator when the operator is attempting to rotate the pump in the direction opposite the direction in which the pump was rotating when last driven by the electric motor or the direction last selected by the operator before loss of power.

Motor passive direction indicator and reversal alarm

A system for controlling and monitoring the extracorporeal circulation of fluids, which is particularly useful in controlling and monitoring the circulation of blood and cardioplegia solution in surgical procedures. A set of perfusion assemblies are mounted in a transportable console, each perfusion assembly having a separable pump and control module pod. Virtually all the instrumentation for the monitoring and controlling of the pump and the fluid being pumped by that perfusion assembly are present on the pump and control module pod for that perfusion assembly, without the need for any separate control screen. Further, the perfusion assembly uses removable circuit cards and associated instrumentation strips to custom configure the perfusion assembly for each application. The perfusion assembly thereby provides complete information at a glance and complete control of the perfusion assembly by using dedicated controls that are grouped to each perfusion assembly. It is flexible in being configured to the desires of the user, is easy to use and involves a minimum of clutter.
