Although the current bladder flushing device is simple, the operation process is complex, professional, requires high privacy, and takes a long time. It is difficult for most clinics to issue or lack the Y-shaped three-cavity catheter. The more difficult problem is that when impurities block, only the catheter can be repeatedly inserted and pulled for processing, which greatly damages the urethra and requires more impurities in the bladder of patients who need bladder flushing. Therefore, the hospital routine clinic basically suspends this operation service, and most of the bladder flushing needs to be hospitalized, which not only increases additional costs, but also chronic urinary tract infection is a disease that needs to be repeatedly and long-term washed by medical professionals. Going back and forth to the hospital is not conducive to the recovery of patients.

[0067] Specifically, the needle cylinder 1 is marked with 50 ml / 100 ml / 150 ml / 200 ml / 250 ml scales on the cylinder body, which facilitates the doctor or the patient to accurately grasp the liquid content in the needle cylinder 1 during use, extracts the medicine according to the actual use requirement, and improves the reliability of the bladder flusher. In other embodiments, the needle cylinder 1 or the push rod 6 can also be designed according to the actual use requirement, for example, a pull ring is designed at the tail end of the push rod 6, and the like, as long as the normal operation of the bladder flusher is not affected.

[0068] In the embodiment, the specific use process of the bladder flusher is as follows. First, the medicine is extracted through the flow diverter 3, the flow diverter 3 needs to be adjusted to the second state, and the first adapter 312 or the second adapter 313 is selected to be communicated according to different medicines. If bagged medicines or bladder flushing liquids and the like are used, the moving part 32 of the flow diverter 3 is adjusted to the state that the first adapter 312 is communicated with the connecting port 311, the bagged object is hung, the medicine directly flows into the infusion tube, the end cover 21 is selected to seal the nipple 2 as required, the medicine is extracted through the needle cylinder 1 or the nipple 2 is directly connected with the catheter, and the medicine can directly enter the bladder. Similarly, if the injection needle is used to extract the medicine, the moving part 32 of the flow diverter 3 is adjusted to the state that the second adapter 313 is communicated with the connecting port 311, the medicine is extracted to the needle cylinder 1, the flow diverter 3 is adjusted to the first state, the nipple 2 is connected with the catheter, and the medicine is pushed into the bladder to flush.

[0069] When it is needed to drain the flushing liquid in the bladder, it can be directly drained through the needle cylinder 1, or the liquid in the bladder can be extracted through the cooperation of the piston 5 and the needle cylinder 1, and unified discharge cleaning is carried out.
