In order to achieve the purpose, the invention provides the following technical scheme: the utility model provides a prevent drainage bag of urine adverse current, includes the drainage bag, the fixed feed liquor pipe that is provided with of last lateral wall of drainage bag, the upper end of feed liquor pipe vertically is provided with the catheter, the catheter with fixed installation pipe that is provided with between the feed liquor pipe, the upper end and the lower extreme of installation pipe are all fixed to be provided with the fixed pipe of pegging graft, two the fixed pipe of pegging graft respectively with the inner wall of catheter and feed liquor pipe is pegged graft fixedly, the fixed check valve that is provided with in inside of installation pipe, the fixed drain pipe that is provided with of lower extreme of drainage bag, the fixed block that is provided with the symmetry of lateral wall of drain pipe, two the fixed block all with the lower extreme fixed connection of drainage.

Preferably, the front side wall of the drainage bag is longitudinally and fixedly provided with scale marks.

Preferably, the upper end of the drainage bag is fixedly provided with symmetrical connecting bands, and the upper ends of the two connecting bands are fixedly provided with handles together.

Preferably, the drainage bag is made of transparent PVC materials.

Preferably, the feed liquor pipe through the first solid fixed ring of symmetry with the last lateral wall fixed connection of drainage bag, the drain pipe through the second solid fixed ring of symmetry with the lower lateral wall fixed connection of drainage bag.

Compared with the prior art, the invention has the beneficial effects that:

through the common cooperation of installation pipe, fixed pipe and check valve, make the urine of human outflow can only forward flow in the drainage bag, and the inside urine of drainage bag can not reverse flow in human inside to effectively avoid the inside urine of drainage bag to cause the infection to the human body, influence the health.
