Evaluation of a smart drink monitoring device

Liquid supply risk management done for inpatient care of the elderly or persons suffering from diseases is currently a time intensive procedure. The paper describes the design and evaluation of an automatic beverage monitoring system. An electronic device is presented, which is able to measure the fluid intake of the patient and provide an automated documentation and connection to existing software architecture. In a user-oriented study the functionality and acceptance were evaluated and the results show that drinking motivation can verifiably result in temporarily increased hydration.
