  • Publication number: 20100234809
    Abstract: A device and method to constrict or occlude the lumen of a flexible tube may include an occluder under the influence of an elastic force, such as a spring force, that can compress a portion of the wall of the flexible tube. The occluder can be under the influence of the elastic force, but prevented from occluding the tube by a stop. The stop can be connected to a tube gripping feature, so that a pulling force on the tube near the gripping feature can disengage the stop from the occluder, releasing the occluder to compress the tube. In some embodiments, the pulling force applied to the tube causes movement of the gripping feature by taking up slack in a portion of the tube held in the device. In other embodiments, the pulling force applied to the tube causes the tube to stretch elastically near the gripping feature, causing the gripping feature to move, and disengaging the stop from the occluder.

    Abstract: An apparatus for pumping fluid through a flexible tubing is provided. The apparatus uses an electromagnet to activate upstream and downstream pinchers to control fluid flow. An armature is configured to compress the tubing, and in combination with the pinchers creates a fluid flow in the flexible tubing. Downstream occlusions in the tubing can be detected by monitoring for conditions wherein the armature does not close fully. Upstream occlusions in the tubing can be detected by monitoring for conditions wherein the armature does not open fully. A control module can be incorporated into the device for controlling the movement of the components and monitoring for occlusion conditions.

    Abstract: An automatic safety occluder provides an occluder for an infusion set that is biased in a closed position until an electrical signal is received that causes the occluder to open. Should the occluder fail to be installed correctly, or if power is removed, the occluder will return to its biased closed position, preventing free flow. The occluder may also be placed in an integrated unit such that the automatic safety occluder may attach to the tubing as a unit.

  • Publication number: 20100057016
    Abstract: The present invention generally relates to occluders and, in particular, to occluders for use in medical infusion systems. In one aspect, the occluder contains one or more tubes through which fluid can flow, and the occluder can be automatically controlled to allow or at least partially prevent fluid flow. In some cases, the occluder may be constructed and arranged to fail (e.g., due to loss of power) in a “closed” position, i.e., a position that at least partially prevents fluid flow. In addition, in one embodiment, the occluder may be manually overridden, even when in a failed state, by a user. For instance, in the event of a power failure, a user may be able to manually override the occluder to remove tubing from the occluder. Such occluders may find use, for example, in medical devices such as hemodialysis machines, medical infusion pumps, plasmapheresis devices, and the like.

The rocker arms are flexible to allow the locking protuberances to move in and out of gaps formed around the rocker arms for closing and opening the conduit clamp. The upper member has a pair of sidewalls and a lower extending projection therebetween. The extending projection closes the pathway in the flexible tube as the conduit clamp moves to a closed position.

  • Publication number: 20080243089
    Abstract: A color-coded slide clamp for controlling the flow of fluid or other substance through an I.V. delivery tube. Each slide clamp generally comprises two longitudinal sides connected at one point by a resilient transverse end. At an opposing end, the longitudinal sides include crimping surfaces, which are clamped around the flexible delivery tube to regulate the flow of fluid passing there through. The precise width of the longitudinal sides determines the rate of flow of the fluid that may pass through the delivery tube. The wider the sides are, the lower rate of fluid that may pass through the tube. The width of the sides is fixed at the time of manufacture to correspond to a single, steady flow rate. The flow rate of the clamps can be easily identified by a color coding scheme. Alternately, clamps can be color-coded for easy identification of the type of fluids passing through the tubes.

  • Patent number: 7419133
    Abstract: A clamp apparatus for selectively occluding a resilient tube to prevent free flow of fluid in the tube. The device comprises a base member to which the resilient IV tube is attached or through which it passes, and a slide clamp that slides relative to the base member and relative to the tube. The aperture in the slide clamp has a relatively open hole at one end, through which the tube passes when the slide clamp is an open position, allowing fluid to flow through the tube. The aperture also has a relatively constricted slot at the other end, through which the tube passes when the slide clamp is in the occluding position, preventing fluid flow through the tube. A deflectable cantilevered locking arm on the base interlocks with a detent on the slide clamp to lock the slide clamp at the occluding position to avoid inadvertent free flow. A release tab that is used to release the locking arm from the slide clamp is located off center to avoid inadvertent activation.

  • Publication number: 20080091150
    Abstract: The present invention describes IV regulators that allow interruption of normal controlled-flow for a safe and convenient bolus flush, either for a specific period of time or for a specific volume of saline flush. Two time-controlled IV regulators are shown, one employing a pneumatic cylinder counter-opposed by elastic band(s) for administering a bolus flush, and one employing a compressible lever and torsion spring counter-opposed by a rotary damper. In both cases the mechanisms disengage the roller-clamp from the IV tube for a predetermined amount of time to fully open fluid flow there through for a bolus flush before return to the regulated-flow position. The volume-controlled flow regulator employs two internal bladders and allows one bladder to fill while the other bladder drains (and vice versa) by flipping a slider paddle-type toggle, thus enabling the administration of a set volume of flush fluid.

  • Patent number: 7316696
    Abstract: A polymeric, surgical clip having first and second curved legs joined at their proximal ends by a flexible hinge section and movable from an open position to a closed position for clamping a vessel between curved opposing inner surfaces. The first leg terminates at its distal end in a female locking member comprising a resilient inwardly turned hook having a recess in the mouth of the hook, and the second leg member terminates in a male locking member complimentary to the female locking member and comprising a detent such that when the first and second leg members are moved from an open position to a closed position about the hinge section the hook member will deflect about the distal end of the second leg member thereby engulfing the male locking member in the mouth of the hook and matingly engaging the detent in the recess thereof, thus securely locking the clip in the closed position. The locking feature provides greater closure security to the clip when clamping large diameter or uncompressible tissue.

  • Patent number: 7074212
    Abstract: A flow regulator device and an associated method of using the device to constrict the flow of fluid through an intravenous line is disclosed. The device comprises a first component pivotally attached to a second component by a hinge. The first and second components are coupleable together into a closed book-like position for enshrouding an intravenous transfer line within a cylindrical tubing channel traversing along the device. A semi-elliptical pinch-off wheel is attached to the device so that the enshrouded transfer line may be progressively pinched off by the semi-elliptical pinch-off wheel in order to variably restrict the flow of liquid through the transfer line. A crossbar having an indicating end is attached to the wheel for indicating the flow rate through the enshrouded and constricted transfer line. The method of using comprises the steps of adjusting, attaching, hanging, injecting, noting, obtaining, placing, pushing, recording, rotating, securing, sterilizing, turning, and twisting.
