Problems solved by technology

In addition, CRRT introduces a high-precision weighing feedback system to continuously record the weight of fluid added to the human body and the weight of waste fluid removed from the human body to achieve precise fluid exchange and dehydration control, and can provide continuous treatment for a long time or even several days; the dialysis machine does not have a scale Heavy feedback, long time will produce cumulative error, only used for treatment within a few hours

Abstract

The invention discloses a blood purification system and a pipe pre-filling control method of the blood purification system. The system comprises a blood pump, a waste liquid pump, a replacement liquid pump and a flow division pump and / or a liquid supplying pump; the flow division pump is arranged between the dialysis fluid inlet of a dialyzer and the outlet of the replacement liquid pump; the liquid supplying pump is arranged between a liquid supplying end and the inlet of the blood pump. According to the blood purification system and the pipe pre-filling control method of the blood purification system, automation and intelligence without artificial interference of the full pipe pre-filling process are achieved, automatic pressing and sealing tests can be conducted in the pre-filling process so that it can be guaranteed that the pipe connectors are connected well, and the blood purification system can automatically prompt a user to conduct the next step of operation in a sound-light alarm mode after passing the sealing tests.

Description

technical field [0001] The invention relates to the technical field of medical devices, in particular to a blood purification system and a method for controlling prefilling of pipelines of the blood purification system. Background technique [0002] CRRT (continuous renal replacement therapy) is continuous renal replacement therapy. It is a general term for all treatments that continuously and slowly remove water and solutes. It is a blood purification technology that supports the functions of human organs. With the development of blood purification technology, CRRT is not limited to the treatment of acute and chronic renal insufficiency, but has gradually expanded to multiple organ dysfunction syndrome (Multiple organ dysfunction syndrome, MODS), systemic inflammatory response syndrome (systemic inflammatory response syndrome, SIRS) , Rescue and treatment of acute and severe patients such as fulminant hepatic failure and severe hemorrhagic necrotizing pancreatitis. [0003...
