Description

Technical Field

[0001] The utility model relates to the technical field of medical devices, in particular to a urinary catheter. Background Art

[0002] A urinary catheter is a tube that is inserted through the urethra into the bladder to drain urine.

[0003] At present, a urinary catheter needs to be used in conjunction with a urine bag. The urinary catheter in the patient's body is connected to the protruding part of the head end of the urine bag catheter through the rubber part at the rear end of the catheter body to achieve the connection between the catheter and the urine bag. The connection is less stable and prone to leakage. When the patient moves, he needs to pull the catheter to lift the urine bag, which cannot effectively free his hands and is inconvenient to use. In addition, the length of existing catheters is generally fixed. When the patient moves and turns over, the catheter is easily pulled, which increases the pressure on the urethral opening and causes poor patient comfort. Therefore, it is necessary to provide a urinary catheter to solve the above problems. Utility Model Content
