    Abstract: Disclosure is made of a precision hydraulic energy delivery system that directly couples the pump to a primary mover (motor) and a related motor control. The system provides flow control of a hydraulically driven machine without the use of downstream devices by employing motion control algorithms in the motor control. Control features are electronically integrated into the hydraulic system by using control algorithms and subroutines specifically developed for the prime mover servo control system coupled to the pump.

    Abstract: A volumetric pump for administering intravenous fluids to a patient includes a first housing having an elongate cavity therein with an open and a closed end. A resilient sheet of material having a centrally-located aperture covers the open end, and a pump shaft is slidably disposed through the aperture to form a sphincter seal therebetween. An inlet conduit leading from a fluid source (an IV bag) passes through the housing into the cavity near the open end thereof, and an outlet conduit leading to a fluid sink (the patient) passes through the housing from the cavity near the closed end thereof. A drive shaft is attached to the pump shaft to drive it back and forth in reciprocating motion inwardly and outwardly of the cavity to produce, respectively, a positive pressure forcing fluid out of the outlet conduit to the fluid sink, and a negative pressure forcing fluid from the fluid source through the inlet conduit. A second housing encloses the first housing and pump shaft, and includes a seal formed about the drive shaft to seal the inside of the second housing from the outside.

    Abstract: A micropump that includes: a tube frame including an elastic tube, and a tube guide groove for attachment of the tube in the form of an arc; a cam drive wheel whose rotation center is the same as an arc center of the tube guide groove, and moves in response to a motor that can be rotated in forward and reverse directions; a first cam that is axially fixed to a center axis of the cam drive wheel, and is provided with a finger depression section at a circumferential portion thereof; a second cam that is pivotally supported by the center axis of the cam drive wheel to be able to rotate, and is provided with a finger depression section at a circumferential portion thereof; and a plurality of fingers provided between the tube and the respective finger depression sections of the first and second cams radially from the rotation center. The micropump can be in a first state of continuously feeding a fluid by, when the first cam is rotated in the forward direction, the first cam pushing and rotating the second cam in the same direction, by the finger depression sections of the first and second cams respectively depressing the fingers one by one, and by the fingers sequentially closing and opening the tube repeatedly from a fluid inflow side to a fluid outflow side, a second state of rotating only the first cam in the reverse direction at a time of, in the first state, a detection of a position where the finger depression section of the second cam releases the tube from depression by the fingers, and a third state of stopping the first cam from rotating at a time of, in the second state, a detection of a position where the first cam releases the tube from depression by the fingers. The first state is retained by a drive command coming from the micropump being in the third state.

    Abstract: A method and apparatus for controlling bi-directional fluid flow. The apparatus has a pump that operates in a continuous pump cycle having a pressure phase and a vacuum phase. A conduit connects a common pump port to a utility port. An electrically-controlled valve regulates air flow through the conduit. The valve operates between a first position isolating the pump and the utility port, and a second position connecting the pump and the utility port in fluid communication. A detector continuously detects and communicates a signal identifying whether the pump is operating in the pressure or vacuum phase of the pump cycle. A controller uses the detector signal to synchronize actuation of the valve with the pump cycle to generate either continuous positive or continuous negative pressure at the utility port.
