摘要： 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.
