[0001] This utility model relates to the field of urinary catheter technology, and in particular to a high-safety urinary catheter. Background Technology

[0002] A urinary catheter is a tube inserted into the bladder through the urethra to drain urine. It is made of natural rubber, silicone rubber or polyvinyl chloride. After the urinary catheter is inserted into the bladder, there is a balloon near the tip of the catheter to keep it in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine. When a urinary catheter is used, it is inserted into the urethra. With a person's movement, the catheter at the urethral tip will shake. This not only causes pain to the patient, but also causes wear and tear on the urethra over time, resulting in poor comfort. Utility Model Content

[0003] Therefore, it is necessary to address the issue that wobbling of the catheter at the urethral tip not only causes pain to the patient, but also leads to wear and tear on the urethra over time, resulting in poor comfort. A highly safe catheter should be provided.

[0004] A high-safety urinary catheter is provided, comprising: an outer tube, on the surface of which an elastic ring is embedded and installed, and an inner tube is fixedly connected inside the outer tube, forming a fluid conduit between the inner tube and the outer tube; a positioning mechanism, which is installed on the surface of the outer tube and extends to the lower end of the outer tube; wherein the positioning mechanism includes a positioning component installed on the surface of the outer tube, and a diversion component is provided at the lower end of the positioning component, the diversion component being installed at the lower end of the outer tube.

[0005] In one embodiment, the positioning component includes a soft rubber ring sleeved on the surface of the outer tube. The surface of the soft rubber ring near the elastic ring is concave arc-shaped, and a positioning ring is fixedly connected to the surface of the soft rubber ring away from the elastic ring. The surface of the positioning ring away from the outer tube has an annular groove.

[0006] In one embodiment, the diversion assembly includes a diversion head fixedly connected to the lower end of the outer tube, the upper end of the diversion head communicating with the interior of the fluid guiding chamber, the lower end of the diversion head being fixedly connected to a ureter, and the upper end of the ureter being fixedly connected to the lower end of the inner tube.

[0007] In one embodiment, a rubber ring is fitted on the inner wall of the annular groove, and a plurality of rubber protrusions are fixedly connected to the inner wall of the rubber ring.

[0008] In one embodiment, the inner wall of the positioning ring is provided with a plurality of circular holes, which are connected to the ring groove.

[0009] In one embodiment, the surface of the rubber bump extends through a circular hole, and the end of the rubber bump contacts the surface of the outer tube.

[0010] In one embodiment, a connecting pipe is fixedly connected to one side of the splitter head, and a control pipe is fixedly connected to the other end of the connecting pipe.

[0011] In one embodiment, a liquid pipe is fixedly connected to the other end of the control tube, and a torsion valve is installed on the surface of the control tube.

[0012] Beneficial effects 1. The aforementioned high-safety urinary catheter, during use, features a soft rubber ring that fits over the surface of the outer tube. This ring, positioned against the proximal end of the patient's urethra, provides a positioning function, preventing the outer tube from moving within the urethra and maintaining a stable position. This reduces catheter movement at the urethral tip, minimizes abrasion of the patient's mucous membranes, and improves patient comfort. 2. By setting up a diversion component, the diversion head can inject liquid from the water bag into the diversion head through the liquid tube and control tube. The set torsion valve can form a good blocking effect on the liquid inside the control tube. The liquid inside the diversion head is injected into the liquid guiding chamber, causing the elastic ring to expand and be positioned in the patient's body. Attached Figure Description

[0017] The following is combined Figures 1-5 This invention describes a highly safe urinary catheter.

[0018] In one embodiment, a high-safety urinary catheter includes: an outer tube 1, with an elastic ring 2 embedded in its surface, and an inner tube 11 fixedly connected inside the outer tube 1, forming a fluid conduit 12 between the inner tube 11 and the outer tube 1; a positioning mechanism 3, mounted on the surface of the outer tube 1, extending to the lower end of the outer tube 1; wherein the positioning mechanism 3 includes a positioning component 31 mounted on the surface of the outer tube 1, and a diversion component 32 is provided at the lower end of the positioning component 31, the diversion component 32 being mounted at the lower end of the outer tube 1; like Figure 1 , Figure 2 and Figure 4 As shown, the positioning component 31 includes a soft rubber ring 311 sleeved on the surface of the outer tube 1. The surface of the soft rubber ring 311 near the elastic ring 2 is concave arc-shaped. A positioning ring 312 is fixedly connected to the surface of the soft rubber ring 311 away from the elastic ring 2. A ring groove 313 is opened on the surface of the positioning ring 312 away from the outer tube 1. A rubber ring 315 is fitted on the inner wall of the annular groove 313. Multiple rubber protrusions 316 are fixedly connected to the inner wall of the rubber ring 315. Multiple round holes 314 are opened on the inner wall of the positioning ring 312. The round holes 314 are connected to the annular groove 313. The surface of the rubber protrusions 316 passes through the round holes 314. The ends of the rubber protrusions 316 are in contact with the surface of the outer tube 1. In this embodiment, during the use of the device, a soft rubber ring 311 can be fitted onto the surface of the outer tube 1, and the soft rubber ring 311 can be pressed against the proximal end of the patient's urethral opening, so that the positioning ring 312 makes contact with the surface of the outer tube 1. During the use, medical tape or other tape can be wrapped around the surface of the rubber ring 315. The surface of the rubber ring 315 is in contact with the surface of the outer tube 1 through the round hole 314 via the rubber protrusion 316. This allows the soft rubber ring 311 to position the surface of the outer tube 1, keeping the soft rubber ring 311 in contact with the patient's urethral opening. This prevents the outer tube 1 from moving with the urethra inside the patient's body, maintaining a stable position of the outer tube 1 within the patient's body and reducing the risk of abrasion of the patient's mucous membrane by the outer tube 1. like Figure 1 , Figure 2 and Figure 5 As shown, the diversion assembly 32 includes a diversion head 321 fixedly connected to the lower end of the outer tube 1. The upper end of the diversion head 321 is connected to the interior of the fluid guiding chamber 12. The lower end of the diversion head 321 is fixedly connected to a ureter 322. The upper end of the ureter 322 is fixedly connected to the lower end of the inner tube 11. A connecting pipe 323 is fixedly connected to one side of the diversion head 321. A control pipe 324 is fixedly connected to the other end of the connecting pipe 323. A liquid pipe 326 is fixedly connected to the other end of the control pipe 324. A torsion valve 325 is installed on the surface of the control pipe 324. In this embodiment, the device uses a diversion head 321 to inject liquid into the inside of the diversion head 321 through a water bag via a liquid tube 326 and a control tube 324. The torsion valve 325 can effectively block the liquid inside the control tube 324, and the urine inside the inner tube 11 can be guided into the urine bag through the ureter tube 322.

[0019] Working principle: During use, the soft rubber ring 311 is fitted onto the surface of the outer tube 1 and abuts against the proximal end of the patient's urethral opening. The positioning ring 312 contacts the surface of the outer tube 1 and is wrapped around the surface of the rubber ring 315. The rubber protrusions 316 on the surface of the rubber ring 315 penetrate the round hole 314 and abut against the surface of the outer tube 1. The soft rubber ring 311 positions the surface of the outer tube 1 and keeps the soft rubber ring 311 abutting against the patient's urethral opening. The outer tube 1 will not move with the urethra in the patient's body and the outer tube 1 is relatively stable in the patient's body.
