[0002] Catheterization refers to the method of draining urine by inserting a catheter through the urethra into the bladder under strict aseptic operation. It is an invasive operation commonly used in clinical practice. This operation is widely used in preoperative preparation, urination difficulties, recording urine volume, and observing the recovery of bladder function in patients with coma, urinary retention, urinary incontinence, etc. However, urinary tract infection caused by catheterization, namely catheter-associated infection (CAUTI), is one of the main causes of nosocomial infection, and catheter-associated infection not only affects the prognosis of patients but also consumes medical resources of hospitals.

[0003] Before using conventional catheterization bags for catheterization, nursing staff need to prepare too many items and the preparation process is complicated. Many patients need catheterization after surgery. The traditional catheterization tools are diverse and numerous, which increases the steps for medical staff to use, and the hygiene and safety of some instruments cannot be guaranteed. In the catheterization bags of the prior art, iodine cotton and lubricating cotton balls are individually packaged in plastic bags, and then integrated with gloves, tube clamps and other parts to form a whole.
