Design of Carryable Intravenous Drip Frame with Automatic Balancing.

Due to the inconvenience of the conventional intravenous drip frame, the piggyback intravenous drip frame is developed to improve the mobility of the patient. However, the current design of the drip frame leads to a lack of balance control and increment of blood returning. To this end, the proposed system aims to solve this problem, and a fuzzy proportionalintegral-derivative control technique is developed to demonstrate the system feasibility.
