Infusion monitoring apparatus and monitoring method thereof

The invention discloses an infusion monitoring apparatus and a monitoring method thereof. The infusion monitoring apparatus consists of a gravity sensor, a data acquisition unit, a data processing unit, terminal equipment and a power source. The infusion monitoring method comprises the following steps of: leading the sum of the weight of an infusion container, the weight of liquid medicine in the container and the weight of accessories to be equal to the initial weight Wo of the liquid medicine, and automatically judging the weight WG of the liquid medicine in the container by analysis software according to the standard of the infusion container; computing the dynamic change numerical value of the infusion speed, the time required for infusing residual liquid and the liquid level liquid quantity in the infusion container by a microprocessor, and when the dynamic change numerical value of the infusion speed and the liquid level liquid quantity in the infusion container exceed the critical alarm points of the dynamic change numerical value of the corresponding infusion speed and liquid level liquid quantity in the infusion container, sending out an alarm signal; and displaying all data of infusion parameters by a displayer, and sending to a nurse center by a wire network or a wireless network, so that the dynamic change process of the infusion process can be timely monitored by medical workers, and the problem of various inconveniences of the medical workers and the patients during infusion can be solved.
