Female urinary catheter and structural member thereof

A female urinary catheter, comprising:

• a urinary catheter main body, wherein the urinary catheter main body is provided with a urinary catheterization channel in a penetrating manner in a length direction;
• an umbrella-shaped anti-off member, wherein a top of the umbrella-shaped anti-off member is provided with a guide wire abutting end, the umbrella-shaped anti-off member is internally provided with a guide wire abutting hollow cavity, an opening end of the guide wire abutting hollow cavity is fixedly connected to an end portion of an insertion end of the urinary catheter main body, and a side wall of the umbrella-shaped anti-off member is provided with a urine inlet;
• a baffle fixing member, wherein the baffle fixing member is sleeved at a periphery of a urination end of the urinary catheter main body;
• a urinary catheterization valve, wherein the urinary catheterization valve is fixedly disposed at an end portion of the urination end of the urinary catheter main body, and the baffle fixing member is located between the urinary catheterization valve and the urinary catheter main body;
• and
• a traction guide wire, wherein the traction guide wire and the urinary catheter main body are disposed independently, and one end of the traction guide wire abuts against the guide wire abutting end after sequentially passing through the urinary catheterization channel and the guide wire abutting hollow cavity, wherein
• the umbrella-shaped anti-off member is made of an elastic material, and the guide wire abutting hollow cavity, the urinary catheterization channel, and the urine inlet are communicated with each other;
• and an outer diameter of the umbrella-shaped anti-off member in a natural state is greater than an outer diameter of the urinary catheter main body, and an outer diameter of the umbrella-shaped anti-off member in a deformed state is equivalent to the outer diameter of the urinary catheter main body.

A structural member for a female urinary catheter, wherein the female urinary catheter comprises a urinary catheter main body, and the urinary catheter main body is provided with a urinary catheterization channel;

• the structural member comprises:
• a urinary catheterization valve, wherein the urinary catheterization valve is disposed at a urination end of the urinary catheter main body;
• and the structural member further comprises:
• a petal fixing member, wherein the petal fixing member is disposed at an insertion end of the urinary catheter main body in a surrounding manner in a circumferential direction of the urinary catheter main body;
• or
• an umbrella-shaped anti-off member, wherein the umbrella-shaped anti-off member is provided with a guide wire abutting end, the umbrella-shaped anti-off member is internally provided with a guide wire abutting hollow cavity, an opening end of the guide wire abutting hollow cavity is fixedly connected to the insertion end of the urinary catheter main body, the umbrella-shaped anti-off member is provided with a urine inlet, and the guide wire abutting hollow cavity, the urinary catheterization channel, and the urine inlet are communicated with each other.
