Artificial biologic valve gradient immersed chemical modification device

The invention discloses an artificial biologic valve gradient immersed chemical modification device, which comprises a multi-stage reaction solution container, a clamp, a moving device, a rotary hanger, a machine frame and a motor. The multi-stage reaction solution container comprises a plurality of reaction solution container for accommodating different modifier solutions for chemical modification of an artificial biologic valve; the clamp clamps the artificial biologic valve and fixes the artificial biologic valve in the rotary hanger, and the rotary hanger is arranged on the moving device and can be controlled to rotate to immerse the artificial biologic valve in the different modifier solutions; the moving device is supported by the machine frame and can be controlled to move vertically to immerse different parts of the artificial biologic valve in the modifier solution; and the motor is fixed on the machine frame to provide power for the moving device and the rotary hanger. The device performs multi-stag
