摘要： An infusion pump for regulating fluid flow through the flow path of an IV tubing set for intravenous administration to a patient. The pumping mechanism of the infusion pump comprises a reversible motor having a drive shaft with a wheel mounted thereon. A valve is provided which is adapted for reversibly closing the flow path through the IV tubing set, and a swing arm is provided. The swing arm has a wheel-engaging portion adapted for engaging the wheel, and an actuator portion operatively linked with the valve to actuate the valve. The arrangement is such that, when the motor is turning the drive shaft in a first direction, the swing arm is moved towards a first position where the actuator portion allows the valve to move to its open position to open the flow path. When the motor is reversed to turn the drive shaft in a second direction opposite the first direction, the swing arm is moved to a second position where the actuator portion moves the valve to its closed position to close the flow path. An infusion therapy system and a method of use of the infusion pump are also disclosed.

摘要： An electrode assembly for use in medical applications including an electrode having a conductor, a lead wire, and a connector. The wire is attached to the conductor with the connector. The connector includes two portions which snap together, and one or both portions have a corrugated wire contacting surface. The wire is held in electrical contact with the conductor between the first and second portions of the connector.
