Intravenous gravity pumps are used to deliver vital body fluids (blood, saline, etc) and high risk medication. These infusion pumps consist of an infusion bag containing the sample fluid mounted on a pole. Although these gravity pumps are used in hospitals, home care settings and emergency vehicles, they have operational limitations. The pumps must be mounted at an elevated height relative to the patient to ensure that a stable amount of fluid is delivered. The elevated height creates the pressure responsible for forcing the fluid out. Any change in the height of the infusion bag or movement of the patient would change the amount of the fluid that is being delivered. This is not suitable for the safe administration of small volumes of chemical/drugs for medication and can cause severe consequences to the patient, even death. Commercial automated pumps that overcome this limitation are very expensive and always require an external power source. This makes the usage

静脉重力泵用于输送重要的体液（血液、生理盐水等）和高危药物。这些输液泵由一个输液袋组成，该输液袋装有安装在一根杆子上的样品液。虽然这些重力泵在医院、家庭护理机构和紧急车辆中使用，但它们有操作限制。泵必须安装在相对于患者较高的高度，以确保输送的液体量稳定。升高的高度产生压力，迫使液体流出。输液袋高度的任何变化或患者的移动都会改变被输送的液体量。这不适用于小剂量的化学药品/药物的安全管理，并可能对患者造成严重后果，甚至死亡。克服这一限制的商业自动化泵非常昂贵，并且总是需要外部电源。这使得用法
