Bladder irrigation device for nursing Technical Field The invention relates to the technical field of medical appliances, in particular to a bladder irrigation device for nursing. Background In urinary surgery clinical care, bladder irrigation is an important means of treating complications such as post-operative bleeding, bladder stones, infection, or mucus obstruction. The conventional operation adopts three-cavity catheter, and the structure of the catheter comprises a balloon filling cavity, a flushing liquid inlet cavity and a urine drainage cavity, so that the basic functions of retention fixation and flushing drainage can be realized. To maintain bladder patency, healthcare workers typically flush by gravity instillation or manual syringe bolus to remove blood clots, debris, or secretions. However, with increasing clinical demands on operating efficiency, patient comfort and safety, traditional irrigation approaches have increasingly exposed significant limitations in dealing with sudden blockages or complex conditions. Although the prior art tries to optimize the anti-blocking performance of a catheter, for example, a bladder flushing anti-blocking catheter with an external filter screen disclosed in Chinese patent CN104415449B can prevent blood clots or tissue fragments from blocking a drainage port to a certain extent, improve drainage stability and relieve discomfort of a patient, but the core problem of flushing and drainage mode switching is still not solved, specifically, the existing three-cavity catheter system still relies on gravity or manual injection for liquid delivery and cannot be quickly switched to a positive pressure pressurized flushing or negative pressure suction drainage mode in the cyclic flushing process, when blood clots or mucus in the bladder are burst to be blocked, a medical staff needs to temporarily disconnect a syringe or an external negative pressure device, the operation is tedious and response is delayed, rescue time is easy to delay, and in addition, because a real-time monitoring mechanism of pressure in the bladder is lacked, flushing safety is judged only empirically, and the risk of bladder mucous membrane damage, urine reflux and pyelous infection is caused by too high pressure, so that the nursing bladder flushing device is necessary to be designed aiming at the defects of the prior art.
