The invention discloses a fast perfusion device for a liver donor during liver transplantation, which comprises a perfusion tube, a fixed sleeve, a fixed shaft, a toothed knob, a spacer sleeve, an adjustment block, a penetrating wire, a one-way valve I, an injection ball, II One-way valve, connecting hose, interface end, telescopic connecting tube, shunt tube, and separation plate, first of all, through the innovative design of built-in plug-in shunt balance chamber, it can avoid the insufficient perfusion of left and right livers, and cooperate with the telescopic cone The tip of the shunt is sharp, which can not only quickly pierce the blood vessel wall and open up the blood vessel, but also can retract to avoid the continuous existence of the sharp tapered end, which improves the safety of the operation. In addition, the front end of the shunt tube is designed in a hole shape, which is convenient for perfusion The liquid flows into the liver quickly, and combined with the one-way liquid injection mechanism, it avoids the reflux situation and ensures the liquid injection effect.
