注射泵系统
摘要：
本发明涉及一种注射泵系统。其中，一种用于从注射器排出流体并且用于减轻闭塞状况的方法，包括将注射器的活塞致动到注射筒内。所述方法监控所述注射器的注射筒内的流体压力，并且当所述流体压力超过预定阈值时确定存在闭塞。所述方法响应于检测出闭塞而将所述活塞致动出所述注射筒预定量，并且将所述注射器的活塞致动到所述注射筒内，直到所述注射器的注射筒内的测量的流体压力超过另一预定阈值。
摘要（英）：

The invention relates to a syringe pump system. A method for discharging fluid from a syringe and for mitigating occlusion conditions includes actuating the plunger of a syringe into a barrel. The method monitors fluid pressure within the barrel of the syringe and determines that an occlusion exists when the fluid pressure exceeds a predetermined threshold. The method actuates the plunger out of the barrel by a predetermined amount in response to the detected occlusion and actuates the plunger of the syringe into the barrel until a measured fluid pressure within the barrel of the syringe exceeds another predetermined threshold.
