Controllable-pressure artificial blood vessel overall water permeability tester and using method thereof

The invention provides a controllable-pressure artificial blood vessel overall water permeability tester and a using method thereof. The controllable-pressure artificial blood vessel overall water permeability tester includes a first joint and a second joint respectively connected with two ends of an artificial blood vessel sample; the first joint is connected with a water tank through a first pipeline, the second joint is connected with a variable frequency pump through a second pipeline, the variable frequency pump is connected with the water tank through a third pipeline, and the variable frequency pump is connected with a frequency converter; a connection part of the second joint with the second pipeline is equipped with a pressure sensor, and the pressure sensor is connected to a pressure gauge for displaying a pressure value measured by the pressure sensor. The controllable-pressure artificial blood vessel overall water permeability tester is adjustable in pressure, simple in structure, convenient to operate, and easy to carry.
