The present invention provides a portable aqueous solution-contactless aqueous solution container state detector and a system for exchanging and managing an aqueous solution container by using the same. The portable aqueous solution-contactless aqueous solution container state detector and the system for exchanging and managing an aqueous solution container by using the same, according to the present invention, enables timely exchange of the aqueous solution container by generating and outputting a notification message according to the detection of a remaining amount of an aqueous solution in the aqueous solution container, has high usability with low costs by simplifying a device and system configuration therefor, increases the portability thereof, enables accurate delivery of the notification message to only selected specific people such as a patient, a guardian and a manager through a portable terminal for receiving the state of the aqueous solution container, improves sanitation by detecting the remaining amount of aqueous solution without coming into contact the aqueous solution, and minimizes a detection error by providing a structure in which the remaining amount of the aqueous solution is directly detected from the surface of the aqueous solution container. The portable aqueous solution-contactless aqueous solution container state detector, according to the present invention, comprises: an aqueous solution container state detection sensor attached to the surface of an aqueous solution container fixed to the upper end thereof at a set height a main body case to which the aqueous solution container state detection sensor is coupled a wireless communication unit mounted inside the main body case to transmit aqueous solution container state information detected by the aqueous solution container state detection sensor to the outside and a fixing module mounted outside the main body case to fix the main body case to a set position. The system for exchanging and ma
