Intravenous therapy is the most common way for the delivery of substances to (hospitalized) patients. The amount of patients receiving some form of Intravenous (IV) therapy is enormous (85−90%). Different techniques exist for the administration of IV fluids. The two main administration techniques are: active (pump based) and passive (gravity based). The active devices are expensive, self-regulating and deliver fluids at a high accuracy. The passive devices are low priced, manually controlled (requiring periodic re-adjustment), and are not accurate. Improvement of the administration control of these passive devices can reduce the cost of therapy, improve the quality of care and make high quality IV therapy more widely available. A new technique for both flow rate sensing and flow rate adjustment is presented. The flow rate sensing technique makes use of a combination of two sensors. This combination of sensors facilitates accurate overall flow rate sensing by combining short and long term flow rate information. A routine for an IV controller is presented, that makes use of the combined sensor actuator system. The new sensor and actuator system was tested in a test setup controlled by a single Integrated Circuit (IC). The measurements of the two sensors showed the variation of flow rate created by the actuator.
