This Inflight Infusion System was designed to meet an urgent operational requirement for accurate administration of intravenous (I.V.) fluid therapy to acutely ill patients while in flight. Aircraft cabin pressure changes affect the flow of intravenous fluids. The discharge rate of I.V. fluids may become excessive during ascent to 2438 m (8000 ft) the level at which both commercial and military aircraft are commonly pressurized, or during loss of cabin pressure, such as may take place at higher altitudes. During descent, the flow rate becomes insufficient or stop until ground level pressure is reached. A method for carefully controlling intravenous fluid intake during all phases of flight with an inflight infusion system that utilizes a modified precision roller pump was developed by the USAF School of Aerospace Medicine. This technique assures carefully controlled fluid intake that is not possible by using the conventional gravity method.
这种飞行输液系统旨在满足一项紧急作战需求，即在飞行过程中对急病患者准确进行静脉输液治疗。飞机客舱压力变化会影响静脉输液的流速。在升至2438米（8000英尺）——商业和军用飞机通常增压到的高度时，或在客舱压力丧失期间，比如在更高海拔可能发生的情况，静脉输液的排出速率可能会变得过高。在下降过程中，流速会变得不足或停止，直到达到地面压力。美国空军航空航天医学院研发出一种方法，通过使用一种改进的精密滚轴泵的飞行输液系统，在飞行的所有阶段仔细控制静脉输液量。这项技术确保了通过使用传统重力法无法实现的精确输液量控制。
