Pneumatosis extracting liquid trap tube capable of controlling depth in chest

The utility model relates to a pneumatosis extracting liquid trap tube capable of controlling the depth in the chest, belonging to the technical field of medical appliance. When the prior drainage tube is used and drainage is carried out for hydrothorax and pneuatosis patient, the depth of the drainage tube can not be controlled because the prior drainage tube has no scale, which increases the difficulty of drainage; sometimes when the drainage tube bumps into the lung lobe of the patient, the pain can be caused; and the alternative operation of the hydrothorax and pneuatosis drainage tube can increase the chances of infection. The pneumatosis extracting liquid trap tube has the following technical scheme that a drainage tube (1) with a scale (2), a left manifold (5) with a hydrothorax drainage switch (4) and a right manifold (6) with a pneuatosis drainage switch (3) are fixedly connected and communicated with each other. The pneumatosis extracting liquid trap tube has the advantages that because the scale is
