The invention relates to a control device of blood purification equipment. The device comprises a main control circuit, a secondary control circuit, a first slave control circuit, a second slave control circuit, a third slave control circuit and a detection device, the main control circuit is used for outputting a first control signal to the first input end of the first slave control circuit, outputting a second control signal to the first input end of the second slave control circuit and outputting a third control signal to the first input end of the third slave control circuit; and the secondary control circuit is used as a new main control circuit when detecting that the main control circuit is in a dead halt state. The problems that when the main control circuit is in a dead halt state, the blood purification equipment has a single fault, and faults of the first slave control circuit, the second slave control circuit and the third slave control circuit interfere with one another are solved.
Description
Technical field [0001] The present application relates to the field of medical devices, and in particular, to a control device for a blood purification device. Background technique [0002] After the blood purification equipment introduces the human blood, filter the specific substance in the blood, and then transfer the purified blood to the human body to achieve the effect of disease treatment; blood purification equipment is a medical device, compared to other general purpose Electronic equipment, during use, medical staff requires a variety of complex, standard operations for blood purification equipment to maintain the operation of blood purification equipment. [0003] A typical blood purification device uses a centralized control. When the controller fails, the blood purification device will enter the fault operating state, and the safety performance of the blood purification equipment is reduced. Inventive content [0004] Based on this, it is necessary to provide a cont...
