Because the inflation connector 200 is provided with the one-way air valve which can prevent the air in the clamping cavity 133 from leaking outwards, the inflation assembly can be detached after the inflation is finished by setting the inflation assembly and the inflation connector 200 into a detachable connection mode, and when the air in the clamping cavity 133 needs to be discharged, the inflation assembly is assembled and connected with the inflation connector 200, so that the comfort of the life of a patient can be prevented from being influenced in the postoperative recovery process.

Wherein, the inflation component can adopt a syringe.

In order to facilitate the drainage tube 100 to be smoothly inserted into the patient during the puncture operation, the preferred embodiment of the present embodiment is: when the drainage tube body 100 is in an uninflated state, the outer contours of the insertion section 120, the operation section 140 and the connection section 130 are kept consistent. Therefore, after the primary puncture operation is completed, the human tissue, the gallbladder wall and the human abdominal wall at the puncture hole can be tightly attached to the outer wall of the drainage tube body 100, so that the sealing performance between the puncture hole and the drainage tube body 100 is improved.

When the outer tubular wall 131 is in the expanded state, the pressure in the clamping cavity 133 is high, so as to prevent the inner tubular wall 132 from collapsing due to the pressure in the clamping cavity 133, and once the inner tubular wall 132 collapses, the patency of the lumen at the inner tubular wall 132 is affected, thereby possibly causing the flow channel 110 to be blocked. In this regard, the preferred embodiments provided in this example are: the strength of the inner tube wall 132 is such that no radial deformation occurs at maximum air pressure in the clamping cavity 133.

In particular embodiments, the inner tube wall 132 may be formed from a rigid material that meets medical standards.
