The non-elastic soft membrane 4 can be naturally relaxed when not stressed, and the elastic soft membrane 4 can be naturally tightened when not pressurized, so that the volume of the variable channel 3 can be reduced in both cases, the soft membrane 4 can be made of different materials such as plastic films, elastic films, cloth materials and the like, and the selection range includes but is not limited to the above example materials as long as the elastic or telescopic flexible membrane-shaped materials can be selected. The soft membrane 4 with elasticity can have a certain extension range when expanding, can prevent the excessive expansion and tearing, and has better use effect. The flexible membrane 4 having elasticity may be designed with folds which unfold when inflated.

In order to expand a larger space in the pipeline body 1 when the variable channel 3 is contracted, the soft membrane 4 extends from the front end to the tail end of the variable pipeline 3 along the axial direction, the soft membrane 4 in the axial direction of the variable pipeline 3 is loosened, and the soft membrane 4 in the axial direction of the variable pipeline 3 collapses towards the gravity direction, so that more space is reserved for the peripheral surface.

Referring to the attached drawings 1-4 of the specification, the pipe bodies of the variable channels 3 are all soft films 4, and the variable channels 3 penetrate through the pipeline body 1 or the sub-channels 2.

In the first embodiment of fig. 1 and 2, only one sub-channel 2 is arranged in the pipe body 1, the sub-channel 2 is a variable channel 3, and the variable channel 3 is entirely a soft membrane 4. The variable channel 3 in fig. 1 is in a contracted state, and at the moment, only one through channel of the pipeline body 1 is arranged, the variable channel 3 in fig. 2 is in an expanded state, the variable channel 3 in the expanded state can play a role in limiting and conveying, and both the pipeline body 1 and the expanded variable channel 3 are available through channels.

In the second embodiment of fig. 3 and 4, the pipe body 1 is divided into two sub-passages 2, wherein one sub-passage 2 is provided with a variable passage 3, and the whole variable passage 3 is provided with a soft membrane 4. the variable passage 3 in fig. 3 is in a contracted state, and the variable passage in fig. 4 is in an expanded state.

In the fourth and fifth embodiments of fig. 6 and 7, both sides of the flexible membrane 4 are fixed on the inner wall of the sub-channel 2, and the flexible membrane 4 and the inner wall of the sub-channel 2 surround the variable channel 3. Wherein two flexible membranes 4 are arranged in the pipe body 1 in the fourth embodiment in fig. 6, the sub-channel 2 is also a variable channel 3.

In the sixth embodiment of fig. 8, the soft membrane 4 is arranged between the two sub-channels 2, and the soft membrane 4, the outer wall of the sub-channel 2 and the inner wall of the pipeline body 1 surround the variable channel 3. The flexible film 4 is connected with the surfaces of the sub-channels 2 and/or the pipeline body 1 in an abutting mode, so that the position of the variable channel 3 is fixed, and the size and the shape of the expansion of the variable channel 3 can be judged and controlled more easily. And the variable channel 3 can be arranged at the corner of the sub-channel 2 and/or the pipeline body 1, so that the variable channel 3 can not occupy the useful space of the sub-channel 2 and/or the pipeline body 1 when not stressed, and the utilization rate of the inner diameter of the pipeline is improved.

The variable multi-channel tube can be used as a suction pipeline, such as various drainage tubes, sputum suction tubes or flow guide tubes, so that multi-channel suction and drainage or multi-channel multifunction of the pipeline can be realized, the service performance can be improved, and the side effect can be reduced.

Referring to fig. 9 and 10, the variable endoscope comprises a control handle 5 and an endoscope tube 6 connected with the control handle 5, wherein the endoscope tube 6 is the variable multi-channel tube. The endoscope tube 6 is a channel body 1, a plurality of sub-channels 2 are arranged in the endoscope tube 6, a soft membrane 4 is arranged in one sub-channel 2, when channels need to be added, the variable channel 3 only needs to be pressurized to enable the variable channel 3 to expand, and the outer diameter of the endoscope tube 6 cannot change.
