Urethral catheter with anti-backflow function

Abstract

The invention discloses a urethral catheter with an anti-backflow function. The urethral catheter comprises a first catheter body, a second catheter body, a urethral catheter opening, a water ball water injection pipe, a water injection connector, a water ball, a side hole, a urethral catheterization end, a through hole, a buffer joint pipe, a breather pipe, a rubber plug, a buffer cavity, a silica gel ring and protrusions. Urine can continue to flow towards the bottom end when entering the buffering cavity in the buffering joint pipe until flowing into the silica gel pad, the silica gel pad is of a circular truncated cone type hollow structure, meanwhile, protrusions are evenly distributed on the inner wall of the silica gel pad, and therefore the urine can be conveyed into the second pipe body; the viscosity of silica gel pad is increased when silica gel pad meets water, the backflow phenomenon of urine in the second tube body can be avoided; the breather pipe is arranged at the topend of the buffering section pipe, the first pipe body can be clamped through the spring clamp, at the moment, the rubber plug is detached, urine below the buffering section pipe can be dredged through the injector, and the problem that the catheter is blocked and cannot be dredged in the using process can be solved.

Description

technical field [0001] The invention relates to a urinary catheter, in particular to a urinary catheter with an anti-backflow function, and belongs to the technical field of catheter application. Background technique [0002] Urinary catheter is a pipeline made of natural rubber, silicone rubber or polyvinyl chloride. It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is a balloon near the tip of the catheter to fix the catheter. The urinary catheter remains in the bladder and is not easy to come out, and the drainage tube is connected to a urine bag to collect urine; the catheter is fixed on the inner thigh (female patient) or lower abdomen (male patient) with a breathable adhesive tape in a well-shaped pattern, and daily The sticking part must be replaced to prevent skin damage caused by long-term sticking or pressure from the catheter. [0003] In the prior art, urinary catheters have been widely...

AI Technical Summary

Problems solved by technology

[0003] In the prior art, urinary catheters have been widely used in the medical field. The structures of existing urinary catheters are generally relatively simple, and the phenomenon of urine reflux is prone to occur during use, which will cause adverse effects on patients. Influence, and the urinary catheter will occasionally be blocked during the catheterization process, it is inconvenient to dredge and clean up
