The invention discloses an air automatically eliminating system for blood pipe used in blood purification, which includes a main engine, wherein a side lever is arranged on the side of the main engine. The main engine comprises an exhausting unit, the side lever is provided with a detection and execution unit, and the detection and execution unit is connected with the exhausting unit through a communication bus. The air automatically eliminating system for blood pipe used in blood purification provides a convenient way during the evolutional precharging of the blood to eliminate air automatically in the blood which enters a dialysis pipe and a water inlet pipe through a dialyzer and the exhausting unit. Meanwhile, the air automatically eliminating system for blood pipe used in blood purification helps medical workers to save time cost in operating of blood purification device, increases stability and reliability in the process of blood purification treatment, and has the advantages of easy operation, high safety and efficiency.
Description
technical field [0001] The invention relates to a medical auxiliary system, in particular to a system with reasonable structure, simple operation, safety and high efficiency for automatically removing air from blood pipelines for blood purification. Background technique [0002] In the process of hemodialysis treatment, it is first necessary to install the pipeline required for blood purification treatment on the blood purification equipment, then fill the blood purification pipeline with physiological saline, and conduct the dialyzer in the pipeline through the semi-permeable membrane. Transmembrane flushing, and finally the blood in the human body is introduced into the pipeline for blood purification treatment. [0003] Existing blood purification equipment needs to empty the air inside the dialyzer and the pipeline when prefilling the blood pipeline with normal saline, but now the main method is to manually knock the dialyzer, using the ratio of air density to water. Th...
