  • Publication number: 20220143299
    Abstract: Fluid management systems are disclosed that include software-controlled, electro-mechanical devices used in combination with single-use or multi-use tubing sets. Functions of the fluid management systems can include fluid pressurization, fluid warming, fluid deficit monitoring (including flow-based and weight-based), suction, fluid collection, and fluid evacuation (including indirect-to-drain and direct-to-drain options). The systems can be configured based on the surgical environment (e.g., operating room or physician office) as well as other user needs and/or preferences.

  • Patent number: 6114789
    Abstract: A switched reluctance motor comprised of a stator having a plurality of evenly spaced, radially oriented, like stator poles that define a gap between adjacent stator poles. Windings for three phases are wound about the stator poles wherein a stator pole of a first phase is disposed circumferentially between a winding and an associated stator pole of a second phase and a winding and an associated stator pole of a third phase. A rotor is mounted for rotation relative to the stator. The rotor has an even number of rotor poles, the rotor poles being dimensioned such that when one of the phases is energized, the rotor poles operatively interact with the energized stator poles such that the motor moves from a first state wherein half of the rotor poles are magnetically coupled to a like number of the stator poles to a second state wherein all of said rotor poles are magnetically coupled to a like number of stator poles.
