Background

Indwelling catheterization is one of the common procedures in urological patients. In the process of indwelling catheterization, the catheter is often blocked by urinary catheter foreign matters such as blood clots, urinary catheter residues, urinary catheter stones and the like. In clinic, a syringe is usually used for repeatedly pumping normal saline and flushing a catheter until the urinary duct of a patient is unobstructed, but a lot of inconvenience exists in the operation. Firstly, the size of the nipple of the injector is not consistent with that of the tail end of the catheter, so that the connection between the nipple of the injector and the catheter is not tight, medical workers have to fix the injector and the catheter by hands, and under the condition, urine extravasation is easily caused to influence the health of a hospital bed, and the risk of urinary tract infection of a patient is increased. Meanwhile, medical care personnel are required to have certain flushing skills, so that the working difficulty is increased. In addition, during operation, the injector needs to repeatedly suck normal saline from the normal saline bottle and then inject the normal saline into the catheter, and the sucked foreign matters in the urinary catheter are discharged out of the injector, so that the injector needs to be separated from the catheter back and forth, and the risk of infection is increased again. For patients with serious and frequent catheter blockage, medical care personnel need to repeatedly push and pull the syringe for a plurality of times and for a long time and continuously exert force, so that the fingers of the operator are red, swollen and painful, and the further work of the medical care personnel is influenced.
