Abstract: A medical infusion device and related method of use for controlling the flow rate of a fluid into a patient's body, comprising: a tube for carrying fluid from a proximal end to a distal end thereof under the action of a driving pressure, which tube is flexible or has a flexible segment at some point along its length; a clamping element capable of preventing fluid flow by fully occluding a portion of the flexible tube or the flexible segment; a movable pusher element for acting variably against the clamping element to variably reduce the occlusion of the clamped portion of the flexible tube or flexible segment and thereby provide a controlled rate of fluid flow; two independently controllable electromechanically controlled actuator elements capable of moving variably over a prescribed range; and a mechanical linkage among the actuator elements, the pusher element and the clamping element.

Abstract: An infusion apparatus for use with a syringe includes a housing enclosing a drivetrain. The drivetrain includes a pinion, spur gears, and a worm gear. One spur gear is arranged to engage with the pinion and another spur gear is arranged to engage with the worm gear. The housing also includes a carriage movable with respect to the housing. A frame on the carriage receives a syringe plunger. A rack on the carriage engages with the pinion to move the carriage parallel to a longitudinal axis of the housing. A pusher assembly of the housing securely engages with the syringe plunger. A motor in the apparatus rotates a worm drive that meshes with the worm gear to drive the drivetrain. A trigger of the apparatus is configured to disengage the worm drive from the worm gear to allow free movement of the carriage relative to the housing.

Abstract: Various methods and devices for driving fluid from a syringe are provided. In one exemplary embodiment, a luer fitting for connecting a syringe barrel to a syringe driver is provided that includes a proximal female end including a socket adapted to be removably mated to a male luer fitting on the syringe barrel. The luer fitting further includes a distal end including a nozzle adapted to receive a fluid conduit. The distal end has a non-threaded axially-oriented annular socket formed therein for removably receiving a protrusion on the syringe driver.

Abstract: Various methods and devices for driving fluid from a syringe are provided. In one exemplary embodiment, a syringe driver is provided having a frame that is adapted to seat a syringe, a driver that is slidably disposed within the frame and that is adapted to seat a plunger of a syringe, and a puller that is slidably disposed within the frame and that has a latch formed thereon for mating to an engagement element on the frame. The device can also include a force-delivery element, such as a constant force spring, that is coupled to and extends between the driver and the puller.

Abstract: An apparatus for monitoring the consumption of fluid by a user, particularly fluids being drank from a container. The apparatus may be used with wide variety of container types. The fluid monitoring unit uses a pair of gears in rotational engagement with each other such that fluid passes around them and rotation of at least one gear is indicative of fluid consumption. The gears in at least one exemplary embodiment are arranged to have low frictional resistance with respect to each other and their respective axles such that the gears quickly and easily rotate and over a wide fluid flow range. This allows the apparatus to accurately and consistently monitor fluid flow from very low flow rates to high flow rates and therefore provide very reliable consumption information. The apparatus in one exemplary embodiment includes an electromagnetic drinking straw embodiment that allows a user to monitor the consumption of fluids from virtually any container type.

Abstract: An apparatus for pumping fluid through tubing comprising a stop platen is disclosed. The stop platen is operatively arranged to depress a wall of the tubing along a section of a longitudinal axis of the tubing. The stop platen is narrower than the tubing along a transverse axis of the tubing. The invention further comprises a cabinet containing the stop platen, a door rotatably fixed to the cabinet, and locking means for preventing rotation of the door. The locking means are operatively arranged to be unlocked by a tubing occluder.

Abstract: A system for securing a wheeled pole, such as an IV pole, to an adjustable height mobile bed to form a movable assembly. The system includes a linkage element with first and second mounting blocks effective to secure the linkage element to an intermediate frame portion of the bed. An elastomeric member is extendable from the linkage element for engagement with a plurality of engagement members disposed on opposite sides of a channel formed in the linkage element. The elastomeric member effectively secures the IV pole in the channel for transport of the IV pole/bed assembly.

Abstract: A syringe driver device is able to effect the controlled, parenteral infusion of a medical fluid using an available disposable syringe. The driver device includes a frame heaving a movable carriage, which houses a force applying element, mounted thereto. A disposable syringe mounts upon the frame and a lengthy microbore tubing attaches to the outlet tip of the syringe. As a force is applied to the syringe plunger, fluid is expelled from the syringe, but its flow rate is dependent upon the diameter of the microbore tubing. The driver device enables the delivery of multiple, sequential doses of fluid.

Abstract: An automated test system is provided for evaluating characteristics of photoreceptors used in the electrophotographic process. The test system includes a retainer for holding the photoreceptor, typically in the form of a cylinder or drum, high voltage power supplies, a charging device, light sources, and non-contact electrostatic surface potential probes, the entirety of the test system enclosed in a light-proof cabinet. A control unit responsive to user defined parameters automatically performs tests for drum substrate surface cleanliness, photoreceptor layer thickness, physical defects, and electrophotographic properties. Linear and circular scanning and fixed adaptable systems are shown.
