The invention discloses a biliary drainage pipe. The biliary drainage pipe comprises a drainage pipe body arranged with a drainage channel; and a drainage hole, which is used for allowing communication between the drainage channel and the external space of drainage pipe body, is arranged at the front end of the drainage pipe body. Thus, when the front end of the drainage pipe body is placed insidethe liver and the gallbladder, draining and rinsing can be performed on the interiors of the liver and the gallbladder through the drainage hole and the drainage channel. Moreover, an airbag is arranged, between the drainage hole of the drainage pipe body and the tail end of the drainage pipe body, on the outer wall; and an gas supply passage communicating with the airbag is further arranged inside the drainage pipe body, so that, inflation of the airbag can be realized through the gas supply passage after the front end of the drainage pipe body is placed inside the liver and the gallbladder,thereby allowing gradual expanded enlargement of the airbag under the action of internal gases. Thus, the interiors of the the liver and the gallbladder are extruded by the extrusion of the airbag soas to achieve certain fixing effects on the drainage pipe body, so that, the problem of accidental slippage of the drainage pipe during retention period can be effectively avoided. In addition, the airbag in the expanded state also has certain dilatation effects on the fistulas; and thus, preparation is done for stage-two surgery.

A catheter has a double-action retention mechanism with (a) one retention mechanism having a reinforced retention body transformable into a deployed flower-like configuration when the catheter is inserted in the bodily cavity, and (b) a stabilizer securing the catheter to a patient's body to maintain a stable position. The retention mechanism for securing the catheter in the bodily cavity is configured with a thickened or reinforced wall portions of the retention body. The inner channel of the catheter body is wider than conventional catheters, thus attaining better drainage and better fluid flow. Due to the reinforced flower configuration, an inadvertent removal of the catheter with the flower configuration fully deployed will afflict no significant damage. When the catheter is to be removed, the catheter's body is disengaged from the stabilizer and the flower configuration of the retention mechanism retention body controllably collapses, thus transforming the catheter to a configuration suitable for removal of the catheter from the bodily cavity. The improved Catheter is simple in operation, safe, prevents from CAUTI, and provides a non-residual urine drainage and high flow rate.
