  • Patent number: 9486589
    Abstract: A method and apparatus for detecting and removing air from a syringe containing a volume of liquid and a volume of gas is described. The method includes moving a piston in the syringe to expel gas through an orifice of the syringe, sensing a movement of the piston in the syringe, and determining when the volume of gas is expelled from the syringe based on a change in the sensed movement. Moving the piston may include applying oscillating force to the piston using an electromagnetic actuator, and displacement and speed of the piston during each oscillation may be sensed. Determining when the volume of gas is expelled may be based on a change in the sensed movement of the piston during one or more oscillations of the piston or based on a comparison to a given reference value.

  • Patent number: 9352574
    Abstract: A fluid ejection device includes a fluid container having a fluid accommodation portion that has formed therein a fluid outlet and accommodates a fluid. A fluid pressing unit presses the fluid accommodation portion to cause the fluid to flow out of the fluid outlet. Connection piping has an end that is connected to the fluid outlet. A fluid ejection unit has a fluid intake port connected to the other end of the connection piping, and ejects in a pulsed manner the fluid received from the fluid intake port. A pressure detection unit detects pressure of the fluid accommodation portion when the fluid pressing unit presses the fluid accommodation portion, and outputs a level of a detection signal corresponding to the pressure. A press control unit stops the fluid pressing unit from pressing the fluid accommodation portion when the pressure indicated by the detection signal is a predetermined value or higher.

  • Patent number: 9204890
    Abstract: A fluid ejection device includes a fluid ejection unit that ejects a fluid and an ejection control unit that controls ejection of the fluid. A fluid container accommodates the fluid supplied to the fluid ejection unit. A pressure adjustment unit adjusts an inner pressure of the fluid container such that the inner pressure gets closer to a target pressure than a first threshold value. The ejection control unit has first and second ejection modes. In the first ejection mode, when the inner pressure is closer to the target pressure than a second threshold value separated from the target pressure farther than the first threshold value, the ejection control unit receives a demand for ejection of fluid. In the second ejection mode, even when the inner pressure is not closer to the target pressure than the second threshold value, the ejection control unit receives a demand for ejection of fluid.

    Abstract: Systems and methods for infusion of fluids using stored potential energy and a variable flow resistor. In one aspect of the present disclosure, there is provided an infusion device that includes a plunger situated within a vessel so as to define a chamber within which a volume of fluid can be accommodated between a downstream surface of the plunger and the vessel. The infusion device further includes an outflow path through which the fluid in the chamber can be dispensed upon displacement of the plunger by a force acting thereon. A variable flow resistor is situated within the outflow path and is configured to allow a substantially constant fluid flow rate from the vessel to be maintained as the force acting on the plunger decreases.
