Apparatus for controlling the rate of dripping of intravenous fluid

摘要

An apparatus for controlling the rate of dripping of an intravenous fluid, comprising (i) drip-detecting means for detecting that an intravenous fluid has dripped into a drip-feed bottle, (ii) a clock for measuring time and indicating the current time, (iii) constricting means connected to a fluid-supply pipe extending from the drip-feed bottle in a downstream direction, for constricting the supply pipe, and (iv) a flow controller for controlling the amount of constriction of the supply pipe by the constricting means, based on a signal of detection of a drip from the drip-detecting means and a time signal from the clock. The apparatus enables one to accurately control the interval of time at which an intravenous fluid drips into the drip-feed bottle and, hence, to administer the fluid to a patient at a desired rate.
