FIG. 1 is a schematic view of a catheter according to an embodiment;

fig. 2 is an enlarged view of a point a in fig. 1.

In the figure:

1. a primary tube; 2. a first branch pipe; 3. a water storage bag; 4. a pipe clamp; 5. a limiting balloon; 6. a second branch pipe; 7. a valve; 8. developing lines; 100. a first lumen; 200. a second lumen; 300. a third lumen.

Detailed Description

As shown in fig. 1 and 2, the urinary catheter of an embodiment includes a main tube body 1 and a first branch tube 2, a first lumen 100 is provided in the main tube body 1, one end of the first branch tube 2 is connected with the main tube body 1 and communicated with the first lumen 100, a water storage bag 3 is provided at the other end of the first branch tube 2, a tube clamp 4 is provided on the first branch tube 2, and the first lumen 100 is communicated with a limiting balloon 5 on the main tube body 1.

The catheter of this embodiment adopts water storage bag 3 to replace the syringe to carry out the water injection, and water storage bag 3's simple structure, the cost is lower than the syringe, only need take off pipe clamp 4 and extrude water storage bag 3 simply and just can carry out the water injection to spacing sacculus 5, does not have this step of syringe water intaking yet, and the water injection finishes the back and utilizes pipe clamp 4 on the first branch pipe 2 to carry first branch pipe 2 and can avoid the backward flow. Therefore, the catheter of the embodiment can greatly simplify the operation, is convenient for medical staff to use and has low cost.

As shown in fig. 1, further, the catheter of this embodiment further includes a second branch tube 6, a second lumen 200 is provided in the main tube body 1, one end of the second branch tube 6 is connected to the main tube body 1 and is communicated with the second lumen 200, the other end of the second branch tube 6 is provided with a valve 7, and the second lumen 200 is communicated with the limiting balloon 5. When the catheter needs to be taken out, water in the limiting saccule 5 can be conveniently drained through the valve 7 on the second branch pipe 6. When the valve 7 is opened, if the pressure in the restriction balloon 5 is sufficient and the pipeline is open, the water in the restriction balloon 5 will be drained from the valve 7 by itself. If the pressure in the stop balloon 5 is insufficient, water in the stop balloon 5 can be pumped out through the valve 7 by means of a syringe or other tool. It should be noted that, the water output of observing among the spacing sacculus 5 should be paid attention to when empting spacing sacculus 5, and the water output should be less than the water injection volume of spacing sacculus 5, makes the surface of spacing sacculus 5 keep smooth, if discharge the water in the spacing sacculus 5 entirely, probably causes spacing sacculus 5 fold, like this can cause the urethra to be scratched when extracting the catheter.

As shown in fig. 1, a third lumen 300 for catheterization is arranged in the main tube body 1, and the first lumen 100 and the second lumen 200 are both opened between the wall of the third lumen 300 and the outer wall of the main tube body 1. The first lumen 100 and the second lumen 200 are isolated from the third lumen 300 for catheterization, so that the first lumen 100, the second lumen 200 and the limiting balloon 5 are not polluted by urine, and the clean state in the first lumen 100, the second lumen 200 and the limiting balloon 5 is ensured.

As shown in fig. 1, a hatching line 8 is provided on the wall of the third lumen 300. The development lines 8 are developed under X-ray, and the specific position of the catheter inserted into the urethra can be confirmed, so that urine leakage and urinary tract injury can be prevented compared with a conventional latex catheter without the development lines 8.

In the embodiment, the valve 7 is made of plastic, is hard in texture and is not easy to deform, so that the injector can be conveniently inserted, and the water pumping operation of medical staff is facilitated.

In this embodiment, the capacity of the water storage balloon 3 is larger than the capacity of the limiting balloon 5. When water is injected into the limiting balloon 5, water can also flow into the first cavity 100 and the like, and water in the water storage balloon 3 cannot completely enter the limiting balloon 5, so that the capacity of the water storage balloon 3 needs to be set to be large, and the limiting balloon 5 can be expanded to a preset size to achieve a good fixing effect.

As shown in fig. 1, the water storage bag 3 in this embodiment is in an ellipsoidal shape, which is convenient for a person to grasp and squeeze with one hand, so that water in the water storage bag 3 can be easily discharged with a small residual amount.

In this embodiment, the water storage bag 3 is made of rubber, so that the water storage bag 3 has a low manufacturing cost.

In the present embodiment, the water storage bladder 3 stores therein sterile water. The water storage bag 3 adopts sterile water instead of normal saline, because the normal saline can be attached to the limiting saccule 5 along with the time, the retraction of the limiting saccule 5 is blocked, and the removal of the ureter is influenced.
