While gravity does enable infusion pumps to operate rather simply, the natural force isn't as consistent and reliable as patients and doctors might hope. Nor is it always terribly convenient. Designers Park Yongwoo and Kim Gyua have reworked the typical intravenous machine, in this case introducing a stepping motor for the precision administering of fluids and medication.
The sleek and minimalist design of the Portable IV System (PIVS) encases the transfusion solution bag behind protective, transparent windows. Inside, pressure is introduced gradually and exactly to the desired dosage, with no need for the apparatus to be elevated. In scenarios such as on-the-ground medicine and emergency response care, treatment accidents can be avoided with this infusion pump, which can simply be slung over the shoulder of the patient himself.
