The utility model relates to the field of
drainage tubes, in particular to an adjustable depth air bag type
pleuroperitoneal cavity drainage tube which comprises a drainage main tube used for guiding seroperitoneum to flow out, and the drainage main tube comprises an internal portion used for being arranged inside an
abdominal cavity and an external portion used for being arranged outside the
abdominal cavity. Annular leather sheaths are installed on the outer side wall of the built-in part at equal intervals, corrugated telescopic parts are arranged at the positions, right opposite to the annular leather sheaths, of the external part, an air bag space is formed between the built-in part and the annular leather sheaths, and a plurality of
branch air pipes for inflating and deflating the air bag space are arranged on the inner side of the drainage main
pipe. According to the adjustable depth air bag type
pleuroperitoneal cavity drainage tube, the depth and the position of the built-in part can be adjusted at any time according to the illness state of a patient, repeated puncture and
cross infection are avoided, adjustment data are clear, pain stimulation caused by tube rearrangement of the patient is reduced, and the economic burden is relieved. And secondly, the operation method is simple and easy to learn, and fine adjustment can be carried out on
