1. A method for determining empty state of an IV bottle, comprising:
- (a) providing an IV infusion monitoring device for measuring infusion data, said infusion data including weight of remaining medical liquid in said IV bottle, infusion rate, remaining time from completion of IV process, and empty state of said IV bottle, said IV infusion monitoring device comprising;
(i) a load sensor for measuring gross weight of said IV bottle including said medical liquid and attachments,(ii) a signal processor havingsignal amplifier for amplifying said measured weight signal and outputting an amplified weight signal,A/D converter for converting said amplified weight signal from analog signal to a group of digital data,microprocessor having memory for storing said digital data and having software for statistically analyzing said a group of digital data as well as for calculating said infusion data,(b) providing a methodology for determining said empty state of said IV bottle, comprising steps of;
(i) said infusion rate being measured and calculated continuously,(ii) said empty state of said IV bottle being determined if a specific effect is observed, said specific effect being selected from the group consisting of needle tip effect, necking effect, and combined needle tip and necking effect.

Abstract
A method for determining the empty state of an IV bottle is provided in an IV infusion monitoring device or in a networking monitoring system, which is cable to monitor the infusion data during whole infusion process. The infusion data includes the weight of remaining medical liquid in the IV bottle, the infusion rate and the remaining time from completion as well as the empty state. It also gives alarm as the measured gross weight of the IV bottle drops to the empty state. The empty state is determined preferably in terms of necking effect and needle tip effect, or their combination.
