Example two: as shown in fig. 6, the first difference from the present embodiment is that: the annular flow guide device comprises an annular baffle plate 23, a plurality of second circular piston valves 24, an annular bell mouth 7 and a second catheter 10; annular pipe 8 cup joints on circular pipe 9, and the one end of annular pipe 8 is connected with the bottom of expansion bag two 13, and the other end and annular horn mouth 7 fixed connection of annular pipe 8, the lateral wall of annular baffle 23 and annular pipe 8's inside wall fixed connection, a plurality of circular piston lamella two 24 inlay and locate in annular baffle 23.
In this embodiment, a plurality of circular piston flaps two 24 are arranged on the annular baffle plate 23 three, when an operator urinates, the catheter two 10 can be inserted into any one circular piston flap two 24, and the other circular piston flaps two 24 are in a sealing state, so that urine can only flow out of the catheter two 10.
The working principle is as follows: the top of the first expansion bag 15 is provided with a first liquid inlet device, the side walls of the second expansion bag 13 are symmetrically provided with two second liquid inlet devices, so that urine can directly enter the two expansion bags, and the first expansion bag 15 and the second expansion bag 13 expand to press the bladder 12, so that the effect of preventing urine leakage is achieved; the circular flow guide device is arranged at the bottom of the first expansion bag 15, the annular flow guide device is arranged at the bottom of the second expansion bag 13, and urine in the first expansion bag 15 and the urine in the second expansion bag 13 can be discharged through the circular flow guide device and the annular flow guide device respectively, so that the urine leakage phenomenon can be prevented when the bladder 12 stoma is replaced, the urine collection bag does not need to be hung all the time, and the portable effect is achieved.
The present embodiment is only for explaining the present invention, and it is not limited to the present invention, and those skilled in the art can make modifications of the present embodiment without inventive contribution as needed after reading the present specification, but all of them are protected by patent law within the scope of the claims of the present invention.
