Description
Technical field
The present invention relates to a kind of catheter, the disposable external catheter of especially a kind of Pascal.
Background technique
It is well known that medically, being per urethram inserted into catheter to bladder, draining urine.Urethral catheterization is divided into catheter retaining
Property urethral catheterization and intermittent two kinds of urethral catheterization.The former catheter is retained in always in patient body, is just pulled out or periodically in state of an illness license
More renew pipe.The latter is then primary every urethral catheterization in 4-6 hours, extracts catheter after bladder emptying.Either indwelling
Urethral catheterization or intermittent urethral catheterization, patient will not only bear the pain that catheter is inserted into bladder from urethra, and there are also the danger infected
Danger.Therefore, a kind of Pascal disposably external catheter is designed, is the current technical issues that need to address.
Summary of the invention
Technical problem to be solved by the invention is to provide a kind of disposable external catheters of Pascal.
The present invention solves the technical solution of its technical problem:
Pascal's disposably external catheter, including urine storehouse, urine storehouse are fixed on substrate, and it is vertical to be fixed in the middle part of urine storehouse
The internal diameter of cylinder barrel, cylinder barrel is up big and down small, the internal diameter of cylinder barrel upper section and the diameter matches of piston, the lower section internal diameter and internal of cylinder barrel
The diameter matches of ultra-fine water conservancy diversion micropin nozzle are equipped with piston and the ultra-fine water conservancy diversion micropin nozzle of internal, in the upper end of cylinder barrel in cylinder barrel
Equipped with high pressure gas suction nozzle, it is equipped with the negative pressure gas nozzle being connected to urine storehouse on the side wall in urine storehouse, has in the upper section cavity wall of cylinder barrel
The urination hole being connected to urine storehouse.
As a preferred solution of the present invention, it is equipped with mistress on substrate and encloses tripe patch ixoderm.
As a preferred solution of the present invention, the electromagnetic gas valve being connected to high-pressure air source is equipped on high pressure gas suction nozzle
Ⅰ；The electromagnetic gas valve II being controlled to a vacuum pump is equipped on negative pressure gas nozzle.
As a preferred solution of the present invention, the bottom in urine storehouse is equipped with urine export indicator light and urine detection touching
Point.
As a preferred solution of the present invention, contact start switch I, contact start switch II and urine are equipped on substrate
Detect contact.
As a preferred solution of the present invention, the urine storehouse is that transparent material urinates storehouse, and band display is equipped on urine storehouse
The negative pressure display bottle of scale.
Application method and principle of the invention:
It will place this invention into patient first, and the ultra-fine water conservancy diversion micropin nozzle of internal is made to be in the surface of patient's bladder；
Negative pressure gas nozzle is connected to vacuum equipment and is opened vacuum equipment again, urine storehouse is vacuumized, third is of short duration by high pressure gas suction nozzle
It is connected with high-pressure air source, piston moves down under the action of high pressure gas at this time, and the ultra-fine water conservancy diversion micropin nozzle of internal is driven to move down, directly
It is imported in the bladder of patient to by the ultra-fine water conservancy diversion micropin nozzle of internal, the 4th, cutoff high gas, suppresses urine state since patient is in
I.e. intravesical urine is in normal pressure state, and urine along the ultra-fine water conservancy diversion micropin nozzle of internal and will pass through the urination on cylinder barrel
Hole enters urine storehouse (piston is more than the impact float downward to urination hole of urine at this time), according to hydrodynamics flow law (A Ji
Mead law principle) positive press liquid can rapidly flow toward vacuum cavity (space) principle along channel in confined space, and path is:
Bladder is positive, and to pass through ultra-fine drain micropin nozzle quick for hydraulic fluid body cavity (physiology detrusor effect make pressure rise positive pressure in urine)
Water conservancy diversion is into the urethral catheterization warehouse of external vacuum cavity.
Compared with prior art, the external urethral catheterization storehouse of the present invention is separated with human body, and not only patient is not painful, and operation side
Just.
Detailed description of the invention
