  • Patent number: 8900155
    Abstract: A non-invasive blood pressure monitoring system, includes an air channel having one or more inlet and exhaust ports to ambient air. An electronically controlled pump inflates and deflates a cuff applied to a patient limb with air via the air channel. A water tight sealed housing containing electronic circuitry for processing signals used in deriving a measurement of patient blood pressure in conjunction with inflating and deflating the cuff. The water tight sealed housing also is sealed from the air channel.

  • Patent number: 5814015
    Abstract: A processor driven syringe pump for one or more, typically two syringes, which are held vertically in corresponding pumping stations of a housing unit which itself is typically suspended from an IV pole. The pump features a central display having portions corresponding to each of the syringes operated by the pump. A data entry knob cooperative with a display processor, causes a cursor issue on the display to step through and choose the menu selections. A function knob is operative to select five operating states including: Purge, Setup, Stop, Run and Bolus in a virtual or software driven manner. The syringe holding station includes a pusher assembly having plunger clamp assembly and a load cell to measure force exerted on the plunger flange. An actuation pad and associated linkage provides for easy syringe flange capturing, while a syringe barrel clamp provides for easy syringe loading and secure syringe barrel positioning for many sizes of syringe.
