  • Medical Device Link . Needleless Syringe Improved by Replacing Metal Parts with Plastic
    In the competitive medical device market, it is every manufacturer's goal to improve its devices and make them less expensive to manufacture. Designers at Medi-Ject (Minneapolis, MN) achieved this goal when they significantly improved their Medi-Jector needleless syringe, a product that had already
  • Medical Device Link .
    that low, " says Werner. Typically, he notes, submicroliter pumping is done by a syringe pump, which can dispense fluid in even smaller amounts than the CeramPump 's 0.5- ul limit. But syringe pumps require a pair of valves to admit and discharge fluid, as well as a stepper motor for each valve
  • Medical Device Link . Implantable Pumps Improve Drug Delivery, Strengthen Weak Hearts Complete pump systems may someday replace damaged or defective organs.
    , by heating the shape-memory material. "Once we heat it, it will regain its shape and become a diaphragm again." Another valve design involves a plunger pushed down over a sealing orifice; when heated, the film reverts to its original shape and compresses a syringe. "We use an integrated spring that can
  • Medical Device Link . Spotlight on Pumps and Valves
    a microprocessor-controlled syringe pump for use in pipetting and dilution operations; it is suited for applications where inertness and minimal syringe rinse volumes are desirable. The series also includes the Base Pump, a stepping motor and leadscrew syringe pump module designed to interface with OEMs' own electronics

    Manufacturing News. Originally Published MPMN November 2004 SPOTLIGHT Pumps and Valves Syringe-pump components. Pumping modules are fully supported with software, electronic diagrams, and engineering phone support. This enables a designer to build prototypes or test pumping functions without sacrificing
  • Getting to know stepper motors
    Fluid control and metering can often be more precisely handled by using stepper motors. EDITED BY Stephen J. Mraz Stepper-motor-based syringe pumps automatically dispense precisely controlled amounts of medications and solutions. Unlike an injection administered by a doctor that is quick and over
