  • Patent number: 8382447
    Abstract: An infusion pump uses an improved shuttle mechanism to more reliably pump liquids in low volumes for medical and other purposes. The improved shuttle uses linear translation and wider, symmetric jaws to grasp infusate tubing and pump liquid infusate through the tubing. Adjustment of the linear motion allows a user to also adjust a pumping volume of the infusion pump. Other shuttles with wider jaws may also pump infusate using a rotary motion. In addition, more than one shuttle, such as two or three shuttles, may be used to approximate continuous pumping. A series of several smaller linear shuttles with sequential actuation may be used as a linear peristaltic pump for general peristaltic pump applications.

  • Patent number: 8167259
    Abstract: Rapid attach and release clamps for attaching to supports include a threaded rod, an arm pivotally attached to the threaded rod, and a knob having an exterior surface and an interior surface. The knob defines a passageway sized to fit the threaded rod. A lock comprises at least one thread and is rotatably attached to the interior surface of the knob. The lock is constructed and arranged to move between a closed position with the thread entering the passageway and engaging the threaded rod and an open position with the thread not entering the passageway. A lever is moveably attached to the clamp and constructed and arranged to rotate the lock about a pivot point.

  • Publication number: 20110293443
    Abstract: An infusion pump including a pump actuator; a fluid assembly operable with the pump actuator, the fluid assembly including an outlet line; a housing configured at its front side to receive the fluid assembly and at its backside to mount in either a first orientation or a second orientation to an external support, wherein the housing supports the pump actuator and the fluid assembly in each of the orientations, and wherein the outlet line extends from a surface of the housing; a controller operably connected to the housing; and a display operably connected to the controller and supported by the front side of the housing, the display configured to be rotatable responsive so that information displayed by the display is oriented right-side-up regardless of whether the surface from which the output extends is in the first orientation or the second orientation.

  • Publication number: 20100256561
    Abstract: An infusion pump includes a housing; a user interface carried by the housing; a pump actuator positioned by the housing so as to be able to actuate a medical fluid pump member; and wherein the user interface and the pump actuator are powered interchangeably by a first, rechargeable battery unit and a second battery unit, both the first and second battery units configured to power the user interface and the pump actuator at a place for which outside power is unavailable, and such that the user interface and the pump actuator can be powered by the second battery unit while the first battery unit is being recharged.

  • Patent number: 7766863
    Abstract: An infusion pump which includes a fingerprint reader to verify that a patient or a user is authorized to activate a patient-controlled analgesic button. The fingerprint reader can be integrated into the patient-controlled analgesic button. The infusion pump delivers a dose of medication to the patient if the fingerprint of the patient or user matches a pre-loaded fingerprint.

  • Patent number: 7608060
    Abstract: A drive mechanism for an infusion pump linearly moves a syringe plunger within a syringe barrel supported by the pump and includes: (i) a motor; (ii) a lead screw rotatably connected to the motor; (iii) a slide assembly having a threaded member supported thereon, the threaded member being associated with the lead screw; (iv) an arm having one end connected to the slide assembly and one end adapted to be engaged with the syringe plunger, and (v) the threaded member being rotatably biased in engagement with the lead screw, wherein upon rotation of the lead screw by the motor, the slide assembly linearly moves the arm wherein the arm is adapted to move the syringe plunger within the syringe barrel.
