but because pipe matter is softer, be difficult to fit tightly fully with urethra around urinary catheter, and the large shape of water pocket toughness is fixed, also be difficult to the bladder neck of fitting fully, and the patient after inserting urinary catheter or in indwelling catheter bladder neck and bladder often can be initiatively or non-active (stimulations) contraction cause the effect of urinating, patient intravesical urine very easily spilt or excreted from water pocket and the suitable urinary catheter in neck of bladder applying position and urethra peripheral clearance this moment, daily life to the patient causes worry, and the seepage repeatedly of urine and liquid solute passage more easily cause the chance of patient's retrograde infection.
some neoteric urine-leakage preventive catheters are generally partly started with from the urinary catheter urethra for this reason, rear urethra part at indwelling catheter increases some new devices again, as water pocket, air bag, pass through again doctor's experience secondary to urethra leakage preventive portion water filling (inflation) after the indwelling catheter success, increase around urinary catheter the applying with mucous membrane of urethra, thereby leakproof, but this complex operation, no matter intubate or tube drawing all increase the workload operating procedure, if and the easy overdistension urethra of careless manipulation and damage urethra, and this kind design can make the part urine be trapped in intracavity between bladder water pocket and urethra water (gas) capsule, be difficult to flow, increase infection chance.
Given this, inventing a kind of easily popularizing does not increase clinician's workload, does not substantially increase product cost, and prevents that effectively the catheter of Urine in Patients seepage is imperative.
Summary of the invention
The present invention is intended to make up the deficiencies in the prior art, and a kind of brand-new design is provided, and is convenient, cheap, practicality, safety, aseptic water pocket valve urine-leakage preventive catheter.
Content of the present invention is:
A kind of simple and easy urine-leakage water pocket valve catheter, the brand-new circle skirt shape valve that increases in described water-bag urethral catheter water pocket top.its special character is, be contracted in catheter water pocket part (being similar to colored umbrella packs up) in production and slotting this skirt shape valve of urinary catheter stage by bonding (the nontoxic hydrosol) or the tight umbrella of special process, after urinary catheter to be determined effectively enters bladder, inject water pocket from the water pocket water filling port, this moment, skirt shape valve was just opened (being similar to colored umbrella opens) with the water pocket dilation by water injection, separate with water pocket, the skirt lobe will lean on the pressure of water pocket and intravesical pressure to be fitted in the bladder neck place, just as a thin film covers on outlet, no matter whether the applying of urinary catheter and urethra is tight, the skirt lobe will play the seepage effect of shutting bladder neck, even patient's bladder meeting active or non-active (stimulation) are shunk, when bladder pressure increases, valve also overlays around neck of bladder more closely, without dead space, can prevent effectively that urine from going out external along the urinary catheter periphery leakage, effectively prevent retrograde infection.Take out most water pocket when pulling out urinary catheter, skirt shape valve loses the water pocket support force and umbrella contraction again, and smoothness is pulled out without impact.
The invention has the beneficial effects as follows: 1. do not increase the workload of the clinical indwelling catheter of doctor fully, the filling water pocket fixedly urinary catheter while skirt shape valve open and be attached to bladder neck and once complete antiseep.2. safe and harmless, need not extra means supercharging expansion applying urethra, without urethra expansion damage risk, reduce the unnecessary sense of discomfort in the many places of patient's indwelling catheter process.3. solve leakage problems from the bladder outlet, without dead space, principle is reliable.4. make simply, compare water-bag urethral catheter, increase hardly extra cost.
Simple and easy urine-leakage water pocket valve catheter is as a kind of leakproof water-bag urethral catheter.It has the design feature of brand-new antiseep.The doctor is easy and simple to handle, and the patient effectively prevents urine extravasation, and manufacturer need not large cost change process units and can produce.Can replace existing water-bag urethral catheter by it.It has easy use, and is easy to operate, easily produces safety leak-proof urine, the easily characteristics such as universal.
