摘要： A drive mechanism for delivery of infusion medium a coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. The armature may be configured with a reduced diameter by including a coil cup for supporting the coil including a shelf portion defining at least a portion of a pole surface of the coil cup.

摘要： An electronic control systems and process for infusion devices and pump configurations can provide highly efficient use of electrical power. The system may include a capacitor which is controlled to partially, but not fully discharge, to provide a power pulse to a pump coil. In this manner, the capacitor remains partially charged and need not be re-charged from a fully discharged state. In addition, the power applied to the coil in a given discharge pulse signal may be controlled to correspond to the power needs of the pump, by controlling the degree to which the capacitor is discharged to produce the pulse signal. A power cut-off switch may be provided to control the discharge of the capacitor such that the capacitor is stopped from discharging prior to the actual end of the armature stroke. The time at which the capacitor discharge is stopped may be selected such that energy remaining in the coil after the capacitor stops discharging is sufficient to continue the pump stroke to the actual end of the stroke. The time at which the capacitor discharge is cut off may be based on the location of the armature in its stroke motion. A power disconnect switch may be provided between the capacitor and the battery, to allow the capacitor to be electrically disconnected from the battery during storage or other periods of non-use, to avoid losing battery power due to the inherent leakage of the capacitor during prolonged periods of non-use.

摘要： A piston-type drive mechanism in combination with a positive pressure reservoir for delivery of infusion medium. A coil capable of being electrically activated to provide an electromagnetic field. The coil surrounds a piston channel extending in an axial direction. The piston channel provides a passage for communication of infusion medium from the positive pressure reservoir to an outlet chamber. A piston is located within the piston channel and is moveable axially within the channel to a forward position. The piston is moved toward a retracted position, when the coil is not energized. As the piston is moved to its forward position, pressure moves a valve member into an open position. When the valve member is in the open position, medium from the piston chamber is discharged into the outlet chamber. An outlet is provided in flow communication with the outlet chamber, for discharging infusion medium from the outlet chamber.

The coil surrounds a piston channel extending in an axial direction. The piston channel provides a passage for communication of infusion medium to an outlet chamber located at one end of the piston channel. An armature is located adjacent the coil, on one side of the axial channel. The armature is moveable toward a forward position, in response to the electromagnetic field produced by activation of the coil. A piston is located within the piston channel and is moveable axially within the channel to a forward position, in response to movement of the armature to its forward position. The armature and piston are moved toward a retracted position, when the coil is not energized. In the retracted position of the piston, a piston chamber is formed between the piston and a valve member and is filled with infusion medium. As the piston is moved to its forward position, the piston chamber volume is reduced and pressure within the piston chamber increases to a point where the pressure moves the valve member into an open position. When the valve member is in the open position, medium from the piston chamber is discharged into an outlet chamber located on the opposite side of the coil relative to the armature. An outlet is provided in flow communication with the outlet chamber, for discharging infusion medium from the outlet chamber.
