    摘要： A flow restrictor includes a flexible tube held in a housing and a linear actuator connected through an intermediate link to a distal link via a first revolute joint proximate the linear actuator and a second revolute joint connecting the intermediate and distal links. The distal link has a distal end adjacent the flexible tube and the intermediate and distal links are constrained to move such that when the linear actuator moves the first revolute joint toward the linear actuator, the distal end of the distal link is driven into the side of the tube thereby progressively occluding the flexible tube.

    摘要： According to embodiments, priming systems, methods, and devices are disclosed which allow medical treatment devices which pump fluid to be primed with minimal operator intervention and a high level of convenience. A blood circuit with a filter fitted with one or more air vents on a non-blood compartment is attached to a treatment system and priming fluid pumped slowly through the blood circuit in a loop. The source of fluid may be elevated, or the pumping may generate pressure, such that priming fluid is forced through the membrane of the filter and out the air vent(s). In embodiments, the vents are hydrophobic which prevent fluid from being ejected, so the priming system can run without intervention.

    摘要： Methods and devices for use and handling of intravenous and/or subcutaneous needles, and, more particularly, to safety devices for shielding needles or other sharp articles or devices that present a safety hazard are disclosed. In an embodiment, a needle protective sheath can include a top wall, a bottom wall, and a pair of side walls joining the top and bottom walls. A finger shield extends from the top wall at a front opening of the sheath and is attached to the top wall by a hinge portion. The finger shield can be rotated about the hinge portion to block the front opening so as to secure a needle within the sheath.

    摘要： Methods and systems for reducing electrical leakage current between a patient and a medical device include sensing electrical current in a fluid line and inducing a cancelling electrical current or voltage to reduce the electrical leakage current. A system for implementing the method includes one or more sensors/transducers and a controller that drives the transducer(s) based on signals from the sensor(s).
