摘要： A pumping system for use in medical applications where liquids must be infused and aspirated from a mammalian patient, and whose economics are such that it is cost effective to simply dispose of it after a single use. The system features positive displacement pump(s) such as reciprocating pump(s) containing a damping mechanism to dampen out the peaks and valleys in the fluid pressure that is pumped, which is important for preventing cavitation. The system furthermore features a shut-off valve on the extraction side so that certain injected fluids such as contrast medium, are not immediately pumped out of the patient. In a preferred embodiment, the system also features means for independently controlling the fluid pressure/volume on the infusion and extraction sides, self-priming capability, a continuous fluid path, and visual air bubble detection, with viewports located at important points in the fluid path, such as at pumps and valves.

摘要翻译：一种用于医疗应用的泵送系统，其中液体必须从哺乳动物患者输注和吸入，并且其经济性使得在一次使用后简单处置它具有成本效益。该系统具有容积式泵，例如包含阻尼机构的往复泵，以阻止所泵送的流体压力中的峰和谷，这对于防止空化是重要的。该系统还具有在提取侧的截止阀，使得某些注射的流体（例如造影剂）不会立即泵出患者体内。在优选实施例中，系统还具有用于独立地控制输液和抽出侧的流体压力/体积，自吸能力，连续流体路径和视觉气泡检测的装置，其中视口位于流体中的重要点路径，如泵和阀门。
