Description
Technical Field
The utility model relates to the technical field of medical equipment, concretely relates to novel wicresoft and safe bladder puncture fistulization external member.
Background
At present, the following four methods are adopted at home and abroad for the urinary retention:
1. open cystotomy indwelling catheterization: is the earliest mastered method for urologists to solve the urinary retention.
2. Urethral Foley Catheterization (UFC) is the most commonly used method to clinically resolve urinary retention. The method is to insert a Foley catheter into the bladder through the external orifice of the urethra to achieve the purpose of draining urine. Foley catheters have a water balloon device inside their tip that is filled with water to secure the catheter within the bladder.
3. Clean intermittent self-catheterization (CISC) is performed by the patient himself, using a clean but usually non-sterile method, with regular catheterization performed 3 to 4 times a day. Patients regularly insert catheters into their bladders transurethrally during the day.
4. Traditional suprapubic cystostomy (SPC): procedures must be performed by the urologist, usually under hospital care using Intravenous (IV) sedation or local anesthesia.
The problems that exist are that:
1. the method 1 has the disadvantages of large wound, much bleeding, great pain and slow recovery of patients, and patients with diabetes and hypoproteinemia are difficult to heal and are easy to have surgical infection. Therefore, the open surgery method is gradually replaced by the minimally invasive technology, and is almost eliminated clinically.
2. Method 2 although this method is most commonly used, it has many problems and drawbacks. First, with this approach, the quality of life of the patient is significantly reduced and the total insertion of a Foley catheter into the urethra leads to a lot of discomfort and even intolerability. Second, urinary tract infection occurs at a rate of approximately 3-10% per day during catheter indwelling, with the greater the chance of infection occurring the longer the time the catheter is indwelling. And about 5% of patients develop bacteremia or sepsis, which is life threatening. Third, patient movement is limited during catheter indwelling, and many patients find shame, polyaddition, and movement, etc. Fourth, if there is urethral stricture, successful catheterization is not possible, and urethral injury and bleeding are likely to occur after repeated operation.
3. Method 3, while currently considered to be the preferred method, is painful and embarrassing, especially for shy elderly or incapacitated persons. If the urethra is narrowed, successful catheterization cannot be performed, and the urethra is easy to be damaged and bleed after repeated operation. If the disinfection and aseptic concepts are not strict, the infection probability is very high. Particularly male, and often results in Urinary Tract Infections (UTI) as a result of performing the method, as such methods are generally "clean" but not sterile. In addition, serious complications such as urethral perforation, bladder perforation or urethral stricture formation may occur.
4. The method 4 carries out percutaneous puncture and cystostomy by a 24F metal cystostomy device, is an improvement on the prior urine retention treatment method, but has large and clumsy cystostomy device, sharp edges and corners at the tip part, large tissue cutting injury, easy damage to peripheral organs, high risk of major hemorrhage, low safety, common clinical complications and great care for clinical application.
