AUTOMATIC FLUX CONTROL UNIT FOR INTRAVENOUS TO AUTOMATICALLY CONTROL INJECTION SPEED OF RINGER'S SOLUTION INTO VEIN

摘要

PURPOSE: An automatic flux control unit for intravenous is provided to automatically control the injection speed of Ringer's solution (intravenous and non-oral injection liquid) into a patient's vein. CONSTITUTION: The automatic flux control unit for intravenous includes a Ringer's solution receiving portion, a tube(17) for providing Ringer's solution to a human body, an upper instillation chamber(3), a lower instillation chamber(4), an optical sensor(6), a tube-pushing member(10,11,12,13,14,16) for adjusting flux of Ringer's solution, and a Micom(8). The light sensor installed at the upper part of the lower instillation chamber has a light-emitting portion(5) and a light-receiving portion(6), which sense dropping time of Ringer's solution. Micom calculates flux of Ringer's solution by the signals transmitted from the light sensor, and controls the operation of the tube-pushing member(10,11,12,13,14,16).
