Detailed Description
It should be noted that, without conflict, the embodiments of the present utility model and features of the embodiments may be combined with each other. The utility model will be described in detail below with reference to the drawings in connection with embodiments.
As shown in fig. 1 to 4, the balloon catheter with longitudinal contraction of the utility model comprises a main tube body 1, a drainage interface 3, a catheter head 4, an inflatable balloon 5 and an inflatable interface 6; the drainage port 3 and the inflation port 6 are respectively connected to the rear end of the main tube body 1, the urine head 4 is arranged at the front end of the main tube body 1, and the inflation balloon 5 is arranged on the main tube body 1 and is positioned at the rear side of the urine head 4.
Specifically, as shown in fig. 1 and 2, the main pipe body 1 is provided with two cavities, namely a drainage pipeline 11 and an inflation pipeline 14, the drainage interface 3 and the inflation interface 6 are respectively connected with the tail part of the main pipe body 1, and the drainage interface 3 is communicated with the drainage pipeline 11 of the main pipe body 1; the inflation interface 6 is communicated with an inflation pipeline 14 of the main pipe body 1; in addition, the main pipe body 1 is provided with a development line 13, so that the flow condition of the liquid in the main pipe body 1 can be more clearly observed.
In this embodiment, the main pipe body 1 is a three-cavity pipe, a flushing pipeline 12 is further arranged inside the main pipe body 1, a flushing port 2 is connected to the tail of the main pipe body 1, and the flushing port 2 is communicated with the flushing pipeline 12 of the main pipe body 1.
As shown in fig. 1, a urine head 4 is arranged at the forefront end of a main tube body 1, the cross-sectional structure of the urine head 4 is the same as that of the main tube body 1, both a drainage tube 11 and a flushing tube 12 are provided, and the forefront end of the urine head 4 is of a closed structure.
In addition, the urine tube head 4 is also provided with a drain hole 41 and a flushing hole 42; the drain hole 41 communicates with the drain pipe 11 of the main pipe body 1; the flushing holes 42 can communicate with the flushing pipe 12 of the main pipe body 1.
As shown in fig. 1, an inflatable balloon 5 is arranged on the main tube body 1 and positioned at the rear side of the urine tube head 4, and the front end and the rear end of the inflatable balloon 5 are respectively connected with the main tube body 1 in a sealing way; and a vent hole 15 is formed in the side wall of the main pipe body 1 positioned on the inner side of the inflatable balloon 5, and the vent hole enables the inflatable balloon 5 to be communicated with the inflation pipeline 14.
As shown in fig. 3, a plurality of arc ribs 51 are arranged on the spherical surface of the inflatable balloon 5, and the arc ribs 51 extend along the warp direction on the inflatable balloon and are distributed in a ring-shaped array, similar to 24 warps on a globe. When the inflatable balloon 5 is deflated, the inflatable balloon 5 can be contracted along the warp direction of the inflatable balloon 5 like a lantern due to the restraining effect of the arc ribs 51, so that the wrinkles along the warp direction are formed, and the annular wrinkles along the weft direction are hardly generated.
In addition, as shown in fig. 4, in order to further avoid the occurrence of annular wrinkles in the weft direction during the contraction of the inflatable balloon 5, the inflatable balloon 5 is similar to a swim ring structure, and has a substantially spherical shape, so that the front end connecting portion of the inflatable balloon 5 and the main tube body 1 form an excessive reverse cambered surface, and the rear end connecting portion of the inflatable balloon 5 and the main tube body 1 also form an excessive reverse cambered surface, namely: the cambered surfaces at the front end and the rear end of the inflatable balloon 5 are of double-layer structures, and the double-layer cambered surfaces can be stacked together after the inflatable balloon 5 is contracted and extend for a certain distance along the axial direction.

Compared with the prior art, the two ends of the inflatable balloon are of a single-layer structure, and cannot extend to the two ends in the contraction process, and can only be extruded to the middle, so that annular folds are formed (as shown in fig. 5).
The life buoy type inflatable balloon has a better effect, only folds parallel to the axial direction are generated, annular folds are hardly generated, the folds parallel to the axial direction are consistent with the inserting and pulling directions, and the life buoy type inflatable balloon is smoother in inserting and pulling, so that the pain of a patient can be relieved.
In one embodiment, as shown in fig. 3, in order to further enhance the guiding function of the arc-shaped ribs 51, in the process of producing the inflatable balloon 5, the inner supporting thin steel wires 52 are added in the production mold, and the positions of the supporting thin steel wires 52 are opposite to the arc-shaped ribs 51, so that the arc-shaped ribs 51 after injection molding contain the supporting thin steel wires 52, and the extending directions of the supporting thin steel wires 52 are the same as those of the arc-shaped ribs 51, extend along the warp direction, and are distributed in an annular array, so as to play a role of supporting along the warp direction.
