The present invention relates to an intravenous fluid supply device for automatically extruding and injecting a predetermined amount of infusion fluid at a predetermined time interval in an artificial manner, regardless of the position of the infusion bag, through grafting microprocessor technology. The device provides the convenience of usability even when the infusion fluid storage container (infusion fluid bag) is positioned lower or higher than the part to which the fluid is injected (human body); the geared motor, which is the main source of driving of the extrusion means, is not activated continuously, but is instantly activated at an inputted repetition cycle, thereby reducing the amount of power consumption substantially and enabling application of a small power storage scheme; the extrusion means, the control means, and the battery are contained integrally, thereby minimizing the number of components, and the resulting simplification of structure, compactness of product, and improved portability provide the economic merit of low cost; it is possible to recognize whether the infusion fluid is normally supplied or not, no matter what position the intravenous fluid supply device is placed, i.e., horizontal, vertical, high, or low, without resorting to a conventional drop pipette, either day or night; and the alarm is raised when air is included in the infusion fluid, when the fluid is injected excessively or insufficiently, when the preset total amount of injection is reached, or when the battery voltage is below a preset value, thereby guaranteeing safety. |
