Description

Bootable lateral leakage protection Novel urethral catheter

Technical field

The utility model relates to catheter technical fields, and in particular to a kind of bootable lateral leakage protection Novel urethral catheter.

Background technique

Catheter can be per urethram inserted into pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC) Bladder comes out so as to drainage of urine, after catheter is inserted into bladder, has the fixed catheter of an air bag to stay in close to catheter head end It in bladder, and is not easy, and drainage tube connection urinal collects urine.Catheter model divides 6F~30F according to the perimeter of outer diameter Totally 13 specifications and models, common adult's catheter tube have tetra- kinds of models of 12F, 14F, 16F, 18F, and F number is exactly the millimeter of outer perimeter Number is legal system unit.It is that F=2 π r converts roughly is exactly F (millimeter)=3 times of overall diameter that F, which is exactly French. reduction formula, (millimeter).

Catheter is mainly used for: 1, directly exporting not contaminated Urine specimens from bladder, make Bacteria Culture, measurement bladder holds It measures pressure and checks residual urine capacity, identify renal shutdown and the retention of urine, to help diagnosis.2, urine is released for retention of urine patient, to subtract If hypodynia.3, pelvic organs operation consent is patient urine-guiding, with empty bladder, avoids damaging in operation.4, stupor, the urinary incontinence Or perineum, when haveing damage, retention catheterization is to keep local desiccation, cleaning, after certain disease in the urological systems operations, to promote wing The recovery of Guang function and the healing of notch, need to often do indwelling catheter.5, rescue shock or critically ill patient correctly record urine volume, ratio Weight, to observe renal function.

Current catheter includes multiple types, 1. Foley catheter: being divided into A type and Type B, A type is to have capsule two-chamber or three Chamber rubber urinary catheter；Type B is no capsule single-chamber catheter, clinical in the middle especially with A type two-chamber Foley catheter used as extensive. 2. silicone catheter: being divided into has capsule two-chamber and three-cavity catheter；3. tip catheter: head end is slightly sharp, increases mainly for prostate The patient of raw disease；4. other: metal urethral catheter, bacterium shape catheter etc..In the above catheter, with Foley catheter and silicon Glue catheter is most widely used, the former is in clinical department using more generally, the latter is most widely used in Urology Surgery.

In place of these current catheters come with some shortcomings: 1, it is again intubated or replaces urinary catheter difficulty, it is clinical much to suffer from Person can encounter pull out catheter after, cannot be again insertable into catheter because muscular tone is shunk, original urethral catheterization tube passage occurs Change, or there is narrow position originally, be difficult to carry out second to be intubated, (diameter is about usually using hard seal wire 2mm, the smooth steel seal wire that length is about 60cm) it penetrates inside catheter, original catheter is taken out, then by new urethral catheterization Insertion of the pipe as seal wire, but the front end two sides that catheter is arranged in the urination hole of traditional catheter are split, top is cecum, Therefore it is very low a possibility that changing urinary catheter, to be guided down by insertion seal wire, is nearly impossible.2, clinical many old Patient is because of urination disorder caused by the other reasons such as urethra mechanical obstruction, after being inserted into catheter, since sphincter urethrae is accidental Property diastole cause Urinary wet so that accumulating in the urine of air bag bottom periphery on a small quantity flows out urethra along urinary catheter lateral wall Clothing.It is not no side opening below air bag, so can not generally pass through top when urine is less or when human body is in erect position Urination hole drain, will appear urine side leakage if sphincter relaxation occurs at this time may.3, part male patient row urethral catheterization It is postoperative to will appear penis head or interior road internal orifice discomfort (Most patients are main performance with swollen sense or tingling sensation), due to Current catheter caliber is uniform, all the same from orificium urethrae internum to orificium urethrae externum internal diameter.But male urethra has the dissection of physiological Narrow and wider area, the catheter for using internal diameter uniform can make the side loaded at these positions inhomogenous, lead to male urine Road anatomical narrow positions is larger by pressure, so as to cause sense of discomfort.
