PURPOSE: An automatic injection device for providing intravenous infusion dose to patients is useful for the automatical and correct injection of intravenous infusion dose without any particular effort. CONSTITUTION: An automatic dose injection device for providing intravenous infusion comprises an intravenous injector equipped with a duck-neck pump. The device enables the accurate dose and the injection rate of to be achieved by means of an arithmetic and control process with a microcomputer built in a pump driving control. The driving control has a driving source working based on the current heating and contraction movement. The source is noise-free, super light, low power consumptive and runs for a long time even with a portable battery. The device effects the accuracy of intravenous dose and enables the patient to move without other supporting means such as stand or rack.
