The invention discloses an inductive vagina remanufacturing device. The existing moulds are hard rod bodies made of wood, glass, rubber and the like, the perineum is not comfortable after the moulds are placed into the perineum, the new wound face is easy to damage due to repeated taking out of the moulds for dressing change, and the remanufactured vagina is prone to infection. The device comprises an elastic ball bag, an aerating guide tube, a medicine injection tube, a one-way valve and a pressure sensor. The elastic ball bag is of an integrated structure of a cylinder and a hemisphere after being aerated, a spiral groove is formed in the outer lateral face of the cylinder, and the elastic ball bag is of a hollow structure. Through holes are formed in the lower bottom face of the cylinder of the elastic ball bag and the spherical face of the hemisphere, the medicine injection tube penetrates the through holes, and the medicine injection tube and the elastic ball bag form a cavity. The aerating guide tube is arranged on the lower bottom face of the cylinder of the elastic ball bag, the one-way valve is arranged on the tail portion of the aerating guide tube, and the pressure sensor is installed on one side of the one-way valve. The device is simple in structure. The size can be adjusted through aerating, in situ drainage and dressing change are achieved, damage to the new wound face caused by repeated taking out of the device is avoided, and operation success rate is improved.
