Multifunctional anti-blocking urethral injury prevention bladder irrigation catheter

Abstract

The invention discloses a multifunctional anti-blocking urethral injury prevention bladder irrigation catheter which comprises an inner core pipe and an outer pipe, wherein the inner core pipe is connected with the head part of the outer pipe by a silicone sheet in a convergence type sheet structure, a water inlet is formed in the head part of the inner core pipe, a water outlet is formed in the side wall of the lower part of the outer pipe, and the inner core pipe is movably connected with the tail part of the outer pipe. According to the multifunctional anti-blocking urethral injury prevention bladder irrigation catheter, the design is ingenious, the structural components are simple, no special material is required, the catheter is non-toxic and free of stimulation and corrosiveness, the biocompatibility is good, urethra mucous membrane irritation is reduced, the catheter is suitable for the patients requiring bladder irrigation due to blood clot risks caused by bleeding after the urologic surgical procedures and can be commonly used as an ordinary catheter, the operation is easy, the material cost is low, and the catheter is favorable for clinical wide promotion.

Description

technical field [0001] The invention relates to the field of medical devices, and more specifically, relates to a multifunctional anti-blockage and anti-urethral injury bladder irrigation catheter. Background technique [0002] As we all know, due to the existence of natural orifices in the human body such as the urethra and ureter, the amount of minimally invasive surgery in the cavity accounts for the majority of urological surgery. Most surgical procedures require indwelling urinary catheters, while minimally invasive resection of bladder tumors and minimally invasive procedures for benign prostatic hyperplasia often require continuous irrigation of the bladder. The three-chamber flushing catheter commonly used in existing clinical work generally adopts perforated water inlet and outlet, the opening is small and single, and because three lumens need to be reserved in conventional thick and thin catheters, the water inlet and outlet channels are also relatively thin , pos...

AI Technical Summary

Problems solved by technology

The three-chamber flushing catheter commonly used in existing clinical work generally adopts perforated water inlet and outlet, the opening is small and single, and because three lumens need to be reserved in conventional thick and thin catheters, the water inlet and outlet channels are also relatively thin , small blood clots and exfoliated necrotic tissue can easily block the irrigation catheter in the process of being discharged with the flushing fluid after the operation

Once the urinary catheter is blocked and the bladder is overfilled, the surgical wound will be dehiscated, the closed blood vessels will rupture and bleed, and due to the stimulation of blood clots, the patient will have repeated bladder spasms, which will not only increase the pain of the patient, but also cause uncontrollable aggravation of bleeding It affects the success rate of the operation, and even requires a second operation

[0003] On the other hand, most of the patients in urology are middle-aged and elderly patients. Due to age or physical factors, they are less responsive to anesthesia and wake up slowly after surgery. The indwelling catheter itself will stimulate the urethra, and some patients will be unconscious. Stretching or even pulling out the urinary catheter without clearing it will cause serious damage to the urethral mucosa or even rupture the urethra if the balloon is not removed. Sometimes the balloon will burst when the balloon is pulled and squeezed, and the fragments of the balloon will remain.

In short, urinary catheters, which seem to be simple small devices, are likely to add a lot of work troubles to surgeons in clinical practice, and have adverse effects on patients' health.
