Abstract
An intravenous drip monitoring method is provided. (A) A monitoring initializing signal is received. (B) A loaded weight is measured to be assigned to be an initial weight and a current weight when the loaded weight is smaller than an empty weight in (C). (D) An alert weight is calculated such that the predetermined minimum alert weight is assigned to be the alert weight. (E) The loaded weight is measured and assigned to be the current weight. (F) When the current weight is not smaller than the alert weight, (E) is performed. (G) When the current weight is between the alert weight and the empty weight, an alert module generates an alert signal and (E) is performed. (H) When the current weight is smaller than the empty weight, a reset to zero and a zero offset calibration is performed on the weighting module and (C) is performed.
