Preferably, when described snap fit and described draw-in groove fasten, described expansion annulus stretches out the open-shaped state of described drainage tube body.
Preferably, described expansion annulus is truncated cone-shaped.
Preferably, described drainage tube body is provided with the fixture for fixing described drainage tube body.
Preferably, described fixture is the elastic sheet rubber that centre offers through hole, and described drainage tube body is set in the through hole of described elastic sheet rubber, and the aperture of described through hole is slightly less than the external diameter of described drainage tube body.
Preferably, the internal diameter of described drainage tube body is slightly larger than the external diameter of described interior pipe.
Preferably, the outer surface of described drainage tube body is provided with Parylene coating, and described Parylene coating layer thickness is 0.1 ~ 0.6mm.
Preferably, described politef layer thickness is 0.1 ~ 0.5mm.
Compared with prior art, the beneficial effects of the utility model: the drainage tube of this utility model slip-off preventing comprises drainage tube body and interior pipe, the outer surface of interior pipe is provided with polytetrafluoroethylene floor, interior pipe box is located in drainage tube body, one end of interior pipe is provided with snap fit, one end that drainage tube body is corresponding is provided with the draw-in groove matched with snap fit, and the other end of interior pipe is provided with expansion annulus, and expansion annulus is connected with drainage tube body by flexible pipe.Before using, drainage tube body is inserted without one end of draw-in groove the region needing drain, again interior pipe is inwardly pushed, now expansion annulus is pushed out drainage tube body and softened, drainage tube body is fixed on the region needing drain, by bayonet unit, drainage tube body and interior pipe are fixed again, politef has good self-lubricating and low friction performance, facilitate the promotion of interior pipe in drainage tube body, the drainage tube slip-off preventing of slip-off preventing of the present utility model is effective, convenient treatment, avoids repeatedly intubate to fix, and reduces patient painful.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Fig. 2 is structural representation after use of the present utility model;
Accompanying drawing indicates as follows: pipe, 3-snap fit, 4-draw-in groove, 5-expansion annulus, 6-fixture in 1-drainage tube body, 2-.
Detailed description of the invention
The technical solution of the utility model is further illustrated below in conjunction with drawings and Examples.
As shown in Figure 1-2, the drainage tube of the present embodiment this utility model slip-off preventing comprises drainage tube body 1 and interior pipe 2, the outer surface of described interior pipe 2 is provided with polytetrafluoroethylene floor, politef layer thickness is 0.1 ~ 0.5mm, interior pipe 2 is sheathed in drainage tube body 1, and one end of interior pipe 2 is provided with snap fit 3, and one end of drainage tube body 1 correspondence is provided with the draw-in groove 4 matched with snap fit 3, the other end of interior pipe 2 is provided with expansion annulus 5, and described expansion annulus 5 is connected with drainage tube body 1 by flexible pipe.
Before using, drainage tube body 1 is inserted without one end of draw-in groove the region needing drain, push interior pipe 2 to need drain region again, now expansion annulus 5 is pushed out drainage tube body 1 and softened, drainage tube body 1 is fixed on the region needing drain, by bayonet unit, drainage tube body 1 and interior pipe 2 are fixed again, politef has good self-lubricating and low friction performance, facilitate the promotion of interior pipe 2 in drainage tube body 1, the drainage tube slip-off preventing of slip-off preventing of the present utility model is effective, convenient treatment, avoids repeatedly intubate to fix, and reduces patient painful.
When snap fit 3 and draw-in groove 4 fasten, expansion annulus 5 stretches out the open-shaped state of drainage tube body 1, and expansion annulus 5 is in truncated cone-shaped, and its internal diameter becomes large gradually towards the direction away from interior pipe 2.When snap fit 3 and draw-in groove 4 fasten, expansion annulus 5 stretches out the open-shaped state of drainage tube body 1, now expansion annulus 5 becomes large, drainage tube body 1 is conducive to be fixed on the region needing drain, expansion annulus 5, in truncated cone-shaped, is conducive to expansion annulus 5 and advances in drainage tube body 1 under interior pipe 2 drives or release.
