The present invention discloses a cross-shaped double sleeve drainage tube, including an inner draining tube, a connecting member, an external sleeve tube, an inner guiding tube, a support rack, a block member, and a pressure sensor. A left end of the inner draining tube is formed in an opening, and a right end of the inner draining tube is sealed. A tube wall at the right end of the inner draining tube is provided with an inner draining hole. The connecting member combines the inner draining tube in the tunnel of the inner guiding tube. The left and right ends of the external guiding tube are formed in an opening, respectively. The tube wall at the right end of the external guiding tube is provided with a plurality of draining grooves. The inner guiding tube is installed in the tunnel of the external guiding tube through the support rack. The left and right ends of the inner guiding tube are formed in an opening, respectively, with the left end thereof connected with the tube wall of the external guiding tube. The tube wall of the inner guiding tube is provided with a pressure monitoring tunnel, an infusing tunnel, and an external draining hole. The block member includes a block head disposed in the right end opening of the inner guiding tube to block the opening and a block body to block the right end of the external guiding tube. A gap is formed between the left face of the block body and the right face of the external guiding tube. The pressure sensor is connected to the pressure monitoring tunnel.
