Device and method for testing tightness of pipeline for continuous kidney replacement therapy

Abstract

The invention discloses a pipeline sealing performance testing device and method for continuous kidney replacement therapy. The pipeline sealing performance testing device comprises a pressurizing module, a measuring module, a vision module and a control module. The pressurizing module is used for outputting positive pressure gas or negative pressure gas; the measuring module comprises a measuring container, an air inlet unit and a clamping unit, the measuring container is used for storing liquid and containing a to-be-measured pipeline for measurement in the liquid, the air inlet unit comprises an air inlet pipeline and an air inlet control valve, the air inlet control valve is arranged on the air inlet pipeline, and the first end of the air inlet pipeline is used for being connected with an air inlet of the to-be-measured pipeline; the second end of the gas inlet pipeline is connected with the positive pressure gas outlet and the negative pressure gas outlet of the pressurization module at the same time, the clamping and closing unit is used for clamping and closing a to-be-detected pipeline for clamping and blocking, and the visual module is used for obtaining an image in the measuring container, conducting leakage analysis and then outputting detection data. According to the invention, rapid automatic detection of the tightness of the pipeline for continuous kidney replacement therapy is realized, and full-path detection and shunt detection can be switched.
