  • Patent number: 4589870
    Abstract: A manually operated actuator is described with which small incremental motions of a rod are obtained to advance a piston of a prefilled syringe. The device employs a reciprocally actuated drive element with a hole through which the rod passes freely when the drive element is in a release position. When the drive element is pivoted to a rod engaging position a pair of edges formed by the hole engage the rod and advance it an increment depending upon the amount of linear movement of the drive element. A back-up inhibitor is employed to prevent the rod from moving back when the drive element is returned to a release position. The back-up inhibitor is syringe responsive by employing a mechanism which causes engagement of the rod by the inhibitor when a syringe is attached to the actuator housing. A syringe with specially adapted flanges is described for use with the actuator.
