<p>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 (28), which is controlled to partially, but not fully discharge, to provide a power pulse to a pump coil (24). A power cut-off switch (40) may be provided to control the discharge of the capacitor such that the capacitor (28) 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 (24) after the capacitor (28) stops discharging is sufficient to continue the pump stroke to the actual end of the stroke. A power disconnect switch (41) may be provided between the capacitor (28) and the battery (26), to allow the capacitor (28) to be electrically disconnected from the battery (26) during storage or other periods of non-use.</p> |
