Description

A leak-proof urinary catheter

Technical Field

The utility model relates to the technical field of urinary catheters, in particular to a leak-proof urinary catheter.

Background Art

A urinary catheter is a tube inserted from the urethra into the bladder to drain urine from the bladder. It is generally made of natural rubber, silicone, or PVC. It is mainly used clinically to treat poor urine excretion caused by coma, paraplegia, urinary retention, urological surgery, bladder and urethra tumors, etc.

The existing leak-proof urinary catheter can refer to the Chinese utility model patent with the authorization announcement number CN212016428U, which discloses a leak-proof urinary catheter, "including a drainage tube, the drainage tube is a medical plastic hose, one end of the drainage tube is the drainage end, and the other end is connected to a connection port, and a limiting air bag is provided on the drainage tube, and the drainage tube between the connection port and the limiting air bag is wrapped with an air supply tube and a telescopic tube body in sequence. The utility model urinary catheter injects water into the limiting air bag through the second air supply connection tube, and then pulls back to block the inner opening of the urethra. The tube body connected to the urine catheter bag is inserted into the connection port. By squeezing the manual capsule body, the first ball blocks the second connecting hole, and the gas pushes the second ball and enters the telescopic tube body through the connecting hose, so that the telescopic tube body expands, reduces the gap between the urethra and the telescopic tube body, and avoids urine leakage. By sensing the pressure of the indicating balloon or the pressure gauge on the connecting hose, the pressure in the telescopic tube body is detected to avoid excessive pressure and discomfort to the patient. The telescopic tube body is deflated by rotating the pressure regulating piece."

When the above device is in use, by squeezing the manual balloon, the first ball blocks the second connecting hole, and the gas pushes the second ball and enters the telescopic tube body through the connecting hose, so that the telescopic tube body expands, reducing the gap between the urethra and the telescopic tube body, thereby avoiding urine leakage. However, when the patient with this structure moves, the device may fall off or the balloon may not reduce the gap between the urethra and the telescopic tube body. The device cannot promptly warn the medical staff and make timely adjustments. At the same time, the device is not provided with a structure for tightly mounting with the urine bag pipeline, which makes it easy for urine leakage to occur during the process of docking the device with the urine bag pipeline.

In a preferred embodiment, the outer wall of the catheter body 1 is fixedly mounted with a check valve 2 and an inflation valve 3, the outer wall of the catheter body 1 is fixedly mounted with a balloon 4, and the top of the catheter body 1 is fixedly mounted with a guide head 5. In the above structure, by setting the check valve 2, the check valve 2 only allows urine to flow in one direction to prevent urine backflow, and the inflation valve 3 is used to inflate and deflate the balloon 4, so that the volume of the balloon 4 increases, and the installation of the guide head 5 is limited to prevent the guide head 5 from falling off.

In a preferred embodiment, a spring is movably sleeved on the outer wall of the round rod 16, and one end of the spring is located on the outer wall of the ring 8, and the other end is located on the outer wall of the mounting head 12. In the above structure, the ring 8 is pressed by external force, so that the spring is compressed, driving the round rod 16 to push the block 18 away from the inner wall of the mounting head 12, thereby forming a quick disassembly and assembly.

In a preferred embodiment, a square groove is provided on the outer wall of the mounting head 12, and the square groove is snap-fitted with the clamping block 18. The circular groove in which the round rod 16 slides on the inner wall of the mounting head 12 is communicated with the square groove, and the outer wall inclined surface of the clamping block 18 is adapted to the outer wall inclined surface of the round rod 16.
