Description

Novel easily keep somewhere three chamber catheters

Technical Field

The utility model relates to the technical field of medical equipment, concretely relates to novel easily keep somewhere three chamber catheters.

Background

A catheter is a tube inserted into the bladder from the urethra to drain urine, and is a tube made of natural rubber, silicone rubber or polyvinyl chloride that can be inserted into the bladder through the urethra to drain urine.

The Chinese prostate hyperplasia has high morbidity, the enlarged prostate compresses the urethra, so that urine cannot be discharged to form acute urine retention, the urethra of a patient is pressed to be narrowed, the urinary tract environment is poor, the disposable sterile catheter is simple to place, but due to the small diameter of the catheter, floccules and blood clots in the bladder can cause the blockage of a lumen; and the disposable catheter has no air bag, is easy to separate out in the catheterization process, leads to the failure of catheterization, and improves the risk of urinary tract infection. The three-cavity air bag catheter has thick pipe diameter, closed head and difficult indwelling, and if the urethral catheterization operation action is violent, the urethral sphincter spasm caused by the pain of the patient often appears, the urethral catheterization fails, the urethral catheterization is carried out for many times, and the urethral injury is even caused, and the problem of difficult urethral catheterization of the prostatic hyperplasia patient is not solved.

SUMMERY OF THE UTILITY MODEL

The utility model discloses an overcome prior art not enough, provide a novel easily keep somewhere three chamber catheters, this three chamber catheters designs based on suit application mode, possesses and has alleviateed the patient discomfort, improves advantages such as ureter imbeds success rate, uses more in a flexible way.

A novel easily-indwelling three-cavity catheter comprises a urination pipeline, a flushing pipeline and a balloon water injection pipeline which are integrally manufactured, wherein the flushing pipeline is wrapped on the urination pipeline, the balloon water injection pipeline is wrapped on the urination pipeline, the end part of the inner end of the urination pipeline is communicated with the end part of the inner end of the body of the flushing pipeline, a plug cover is arranged in the end part of the outer end of the flushing pipeline, a water injection balloon valve is arranged in the end part of the outer end of the balloon water injection pipeline, and a balloon is arranged on the inner end of the balloon water injection pipeline;

the urination pipeline comprises a straight pipe section and a bent section which are integrally manufactured, the straight pipe section and the bent section are in smooth transition, the outer end of a connector of the straight pipe section and the inner end of a connector of the bent section are open, and a side hole is formed in the end, close to the inner end of the body, of the bending degree.

The utility model discloses compare prior art's beneficial effect is:

the catheter is suitable for patients with prostatic hyperplasia and urinary retention, bladder urinary fistula, preoperative preparation for pelvic cavity operation and the like, effectively improves the success rate of indwelling the urinary catheter, and greatly reduces the side injury in the indwelling process.

After the catheter with the straight front end is placed in the body, the head end of the catheter can be pushed to the trigone of the bladder of a person, so that inflammation, hematuria and urethral injury of the patient can be caused. Compared with the conventional, the utility model discloses the internal end that stretches into internal catheter accords with the physiology of people bending section, and firstly, this kind of catheter accords with the design of the physiology radian of bladder, more does benefit to the catheter and keeps somewhere. Secondly, the urethra can be attached to the radian of the trigone of the bladder after being placed into the bladder, and the urethra is contacted with the inner wall of the bladder by a curved surface, so that the stimulation and the injury to the urethra of a patient are reduced.

The end part of the internal end of the catheter of the utility model is open (the guide wire is provided with the hole), and the traditional end part of the catheter is closed without the function of urine drainage. The urethral probe has the advantages that firstly, the end part of the inner end of the body is open, so that the urethral probe can be conveniently guided, the front end of the urethral probe is consistent with the curvature of the catheter, the rear section of the urethral probe is straight, and the catheter can be directly kept along the probe from the opening of the inner end of the body. The urethral sound has better guiding function. The end opening and the side hole at the inner end of the body can simultaneously play a role in draining urine, and the risk of blockage after the catheter is left is reduced.

Overall: the utility model discloses the catheter compares with traditional catheter, because the crooked segmental arc of its internal end, can alleviate patient's misery and the reduction of catheterization in-process and keep somewhere back catheter to patient's mechanical stimulation and damage. And the end part of the internal end of the urethral probe is open, so that the urethral probe and the catheter can be matched for use, the success rate of catheterization can be increased, and the violent injury possibly caused by repeated urinary catheterization attempts can be reduced.
