[0002] During the postoperative care of urology patients, the bladder needs to be flushed with a bladder flushing device to avoid bacterial growth and prevent blood clots from forming in the bladder. Liquid medicine or saline is injected into the bladder through a catheter to remove sediment. The Chinese invention patent with the publication number CN115869484A discloses a bladder flushing device for urological surgery care, which belongs to the field of medical care. It solves the problems that the existing devices are not conducive to flushing the bladder and are laborious to operate. It includes a mobile cart, on which three placement plates that are successively smaller are arranged from bottom to top. The upper end of the lower placement plate is provided with a liquid storage tank, a press disinfection bottle, a storage box and a lifting heating rack from front to back. A disinfection box is fixed on the middle placement plate. An extrusion component and a charging component are provided on the upper end of the disinfection box. A visual component is provided on the front side of the disinfection box. A wristband component is engaged with the snap seat. A shift computer component is provided on the top of the mobile cart. A flushing component is provided on the lifting heating rack. The flushing component passes through the extrusion component and the visual component in sequence. The flushing component is connected to a liquid storage tank, a negative pressure pump, a flushing catheter and a charging component. The present invention has a high degree of integration and is easy to operate. It can effectively flush the bladder, add medicine and flush out blockages, analyze the color of the flushing liquid, and judge the flushing situation. However, the existing urological nursing bladder irrigation devices for patients after surgery still have the following problems: 1. During the catheterization or flushing process, the catheterization bag is randomly placed on the floor of the ward, which is inconvenient for subsequent handling of the catheterization bag. People passing by may step on the catheterization bag, and it is inconvenient to adjust the height of the catheterization bag; 2. When the flushing fluid in the bladder is discharged, there may be blood clots in the flushing fluid. When the blood clots are too large, they will block the catheter. The tube is squeezed by a squeezing mechanism, and the blood clots in the catheter are broken down and drained by increasing the local pressure of the lumen. However, the squeezing mechanism is fixedly installed at a certain position of the device and cannot squeeze any section of the catheter at will. Therefore, we propose a bladder flushing device for urological surgery nursing to solve the above problems. Summary of the invention
