BOTTLE STOPPER, INTRAVENOUS INFUSION BOTTLE, FUNCTIONAL COMPONENT, AND INTRAVENOUS INFUSION BOTTLE ASSEMBLY

摘要

A bottle stopper, intravenous infusion bottle, functional component, and intravenous infusion bottle assembly. The intravenous infusion bottle assembly comprises a bottle stopper 20A and a functional component. The functional component can form a communication link with the bottle stopper 20A. The bottle stopper 20A can measure the mass of a fluid within a bottle body 10A. When the functional component determines, on the basis of the mass of the fluid, that the amount of remaining fluid is too low, then the functional component issues an alert so as to prevent an accident.
