The utility model provides a technical scheme for ventricular drainage tube, comprising a drainage catheter, a connector of drainage bag communicating the top end of the drainage catheter and a lateral hole on the bottom end of the drainage catheter. A sepiment within the drainage tube separate the inner cavity of the drainage tube into the major and the secondary cavity. The stated connector of the drainage bag and the lateral hole are communicated with the major cavity of the drainage tube. Below the connector of the drainage bag, a connector outside the major cavity is communicated with the major cavity of the drainage tube, and on the side wall of the drainage tube, a lateral hole is communicated with the secondary cavity of the drainage tube. Below the connector of the drainage bag, a connector outside of the secondary cavity is communicated with the secondary cavity of the drainage tube. The cross section area of the secondary cavity is a third that of the major cavity of the drainage tube. The lateral hole of the secondary cavity is within the distance of 1.8-2.2 cm to the bottom of the drainage tube. On the inferior part of the exterior wall of the stated drainage tube is barium-containing marker, and the stated connector outside the major cavity and the connector outside the secondary cavity can all be used recurrently.
