Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of urinary catheterization devices, in particular to a urinary catheterization device for urology. BACKGROUND

[0002] The urinary catheterization device needs to use a urinary catheter mechanism, which includes a urinary catheter, a drainage tube and a urine collection bag part. The urinary catheter is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride, which can be inserted into the bladder through the urethra to drain urine. Many patients need to use a urinary catheter to drain urine due to various reasons such as surgery, critical illness, shock, urinary incontinence, etc. For male patients, the existing urinary catheter is inserted into the urethra and bladder by a doctor using forceps. In order to reduce the discomfort of the patient, it is necessary to avoid the skewing of the urinary catheter. The doctor needs to hold the forceps by hand, which requires a high level of skill. In order to further facilitate the insertion of the urinary catheter into the urethra, the surface of the urinary catheter is pre-coated with a lubricating liquid. However, if the lubricating liquid is applied in advance, it may fall off or dry out during use, or even be contaminated with a small probability, reducing the lubricating effect. In addition, the urethral orifice is in a closed state, and there may be a slight discomfort during insertion. Finally, the prepuce of some men is too long, which slightly blocks the urethral orifice and affects the insertion of the urinary catheter. In view of the above problems, we propose a urinary catheterization device for urology. SUMMARY

[0003] In view of the above problems, the present application provides a urinary catheterization device for urology. By rotating the outer ring, a negative pressure is generated in the piston cylinder, which pushes the extrusion plate to fix the penis and open the urethral orifice. Then the outer ring is pushed to move the extrusion plate, which opens the prepuce. The push ring is moved by hand, which pushes the flexible plate and causes plastic deformation. The plastically deformed flexible plate fixes the urinary catheter. The push ring is further pushed to move the fixed urinary catheter, thereby avoiding skewing. When the push ring moves the urinary catheter, the push ring also moves the connecting ring. The connecting ring is connected to the liquid inlet ring piston. The pressure in the liquid inlet ring increases, and the lubricating liquid in the liquid inlet ring is applied to the surface of the urinary catheter through the diaphragm of the liquid outlet hole, thereby lubricating the surface of the urinary catheter and facilitating the movement of the urinary catheter in the urethra.

By rotating the outer ring, the piston cylinder is pressurized, the inner pressure piston plate moves to the center end of the sleeve ring, the penis is squeezed and fixed by the two inner pressure plates, the urethral opening of the squeezed penis is opened, and the subsequent insertion of the urinary catheter is facilitated. II.

The inner pressing plates 8 are fixedly connected with piston columns. The piston columns are sealingly movably arranged in a piston cylinder 10. The piston cylinder 10 is arranged in arc-shaped air pressure transmission with the outer ring 7.

[0013] Principle of the application: In use, the ring 1 is sleeved on the surface of the penis. One hand fixes the ring 1, and the other hand rotates the outer ring 7. The rotation of the outer ring 7 drives the rotation of the arc-shaped push tube 22, and then drives the rotation of the piston push plate. Then, the piston push plate inflates the air inlet pipe 23. The air pressure drives the piston column to move to the center end of the ring 1. The piston column then drives the inner pressing plates 8 to move to the center end of the ring 1. The two inner pressing plates 8 close to each other squeeze the penis, so that the penis opening is opened, facilitating the subsequent insertion of the urinary tube. After the inner pressing plates 8 squeeze the penis, the outer ring 7 is manually pushed to move. The outer ring 7 drives the push ring 14 to move, and then drives the piston cylinder 10 to move, and then drives the inner pressing plates 8 to move. The two inner pressing plates 8 open the foreskin of the penis, avoiding the influence of the foreskin on the insertion of the urinary tube. After preparation, the urinary tube is inserted between the circular cavities surrounded by the plurality of flexible plates 13 and extends to the liquid inlet ring 5. The push ring 14 is pushed to move. The push ring 14 squeezes the flexible plate 13. The flexible plate 13 plastically deforms. The plastically deformed flexible plate 13 fixes the urinary tube. The limiting plate 21 contacts the connecting ring 12. The push ring 14 is continuously pushed to move, thereby driving the fixed urinary tube to move. When the urinary tube moves, the push ring 14 drives the connecting ring 12 to move. The connecting ring 12 drives the piston rod 19 to move, and then drives the piston plate 20 to move. The piston plate 20 pressurizes the liquid inlet ring 5. The pressure in the liquid inlet ring 5 increases. The lubricating liquid in the liquid inlet ring 5 is applied to the surface of the urinary tube through the diaphragm at the liquid outlet hole 24, lubricates the surface of the urinary tube, and facilitates the movement of the urinary tube in the urinary tube of the penis.
