  • Patent number: 9057368
    Abstract: A rotary cam actuated linear peristaltic pump includes a plurality of cams which actuate a plurality of pistons. The cams apply a force to the piston by way of a lifter for providing mechanical advantage so that a smaller motor may be used to rotate the cam. Each piston of a plurality of pistons is sequentially raised to the extended position to squeeze a tube so as to flow fluid through the tube.
    Type: Grant

  • Patent number: 7632249
    Abstract: A syringe assist device for preventing vacuum stall in an infusion pump which extracts fluid medication from a conventional syringe. The device is a plunger housed within a front case and a back case. The plunger is comprised of a cocker, a cradle, and a base member. The cocker and cradle are compressively retained by a spring spanning therebetween. The cocker includes a locking member which cooperates with a wedge type locking member defined by the back case to prevent movement along the base member. The cradle includes a syringe barrel compression member. In its unlocked position, the cocker and the cradle slide against the base member in unison, while in its locked position, only the cradle slides against the base member, thereby enabling a unidirectional compressive force upon the syringe. By this compressive force, the vacuum created within the syringe during infusion is eliminated, thereby eliminating vacuum stall.

  • Publication number: 20080021396
    Abstract: A syringe assist device for preventing vacuum stall in an infusion pump which extracts fluid medication from a conventional syringe. The syringe assist device is a plunger housed within a front case and a back case, both of which include a section for holding the infusion pump, and a chamber for compressively retaining a syringe. The plunger is comprised of a cocker, a cradle, and a base member. The cocker and cradle are each configured to enable a sliding relationship with the base member. Additionally, the cocker and cradle are configured to enable a sliding relationship with each other. The cocker and cradle are compressively retained by a spring spanning therebetween. The cocker includes a locking member which cooperates with a wedge type locking member defined by the back case to prevent movement along the base member. The cradle includes a syringe barrel compression member which imparts a compressive force upon the syringe.
