Abstract
The utility model relates to a leak-proof catheter, comprising a catheter. The head part of the catheter is provided with a urine inlet and the tail part thereof is provided with a urine outlet, an air bag that is clamped at the urethral orifice is arranged at one side of the head part of the catheter, the lower part of the air bag towards the urine outlet is of a conical shape tightly jointed with the inner urethral orifice, the air bag is connected with an air-guide nozzle through an air-guide pipe, and the upper part of the air bag away from the urine outlet is of a spherical surface. The leak-proof catheter has the beneficial effects that (1) the conical part at the lower part of the air bag can be tightly jointed with the inner urethral orifice to prevent leakage of urine; and (2) the structure is simple, the cost is low and the operation is easy.
Description
Technical field
This utility model relates to a kind of catheter.
Background technology
The catheter of present clinical use has a variety of, but its air bag all is spherical.When patient's indwelling catheters such as a lot of especial patients such as urethra be lax, owing to catheter can not combine closely with urethra or air bag come-up leave in reason such as urethral orifice can cause and ooze the urine phenomenon, may produce sense of discomfort, infection etc., patient's disease and psychology is all produced harmful effect.Oozing the urine phenomenon, to nurse difficulty bigger, also increased workload to clinical care simultaneously, brings unnecessary work load to the nurse.Chinese patent 200720074669.0 and 200420099224.4 provides a kind of anti-infiltration catheter with air bag respectively, the former absorbs the urine of seepage by the form of setting up the urine absorption bag, the latter then sets up a urethra fixation balloon in the bottom of bladder air sac, the urethra fixation balloon is stuck in the internal urethral orifice after expanding, when urine after the junction seepage of bladder air sac and bladder, the urethra fixation balloon can further stop under the urine and oozes.The improvement of these two kinds of anti-infiltration catheters is not itself to set about from existing air bag, but has increased suction or seal member, and structure is more complicated, the yet corresponding raising of cost of manufacture, complicated operation.Particularly the latter may still be oozed urine or swell the excessive air bag extruding back urethra that causes because of the urethra fixation balloon swells deficiency, causes urethral mucosa, mucosa down even the damage of flesh layer, urethrorrhagia etc.
On the physiology, bladder is cone-shaped cryptomere flesh sexual organ, for storing the usefulness of urine.The inner face of fundus of bladder has delta, is called trigone of bladder, between two ureteric orificies and internal urethral orifice three line.The bottom of bladder is an internal urethral orifice.
Summary of the invention
The deficiency of, complex operation higher for the complex structure, the cost of manufacture that solve existing anti-infiltration catheter the utility model proposes a kind of simple in structure, cost of manufacture is low, easy to operate anti-infiltration catheter.
This utility model adopts following technical scheme:
A kind of anti-infiltration catheter, comprise conduit, the head of described conduit is provided with urine filling mouth, afterbody is provided with the mouth of urinating, head one side of described conduit also is provided with the air bag that is stuck in the internal urethral orifice upper end, described air bag is connected with gas guide nozzle by airway, and the bottom towards the mouth of urinating of described air bag presents the taper that cooperates with internal urethral orifice.
Further, the top away from the mouth of urinating of described air bag is sphere.
Further, it is inner or outside that described airway is arranged on the tube wall of described conduit.
As preferably: described air bag connects an airway.
Perhaps, described air bag connects two airways.
Technical conceive of the present utility model is: the conical design of air bag bottom meets human body physiological characteristics, and the inflation rear gasbag can fit tightly with internal urethral orifice and prevent that urine from oozing out.During use, urethral catheterization technology is routinely operated, and after definite air bag entered bladder, the pumpback catheter was combined closely air bag and internal urethral orifice gently.
The beneficial effects of the utility model are: the conical design of (1) air bag bottom meets human body physiological characteristics, can fit tightly with internal urethral orifice and prevent that urine from oozing out; (2) simple in structure, cost is low, easy to operate, safe in utilization; (3) can produce the catheter that has the different model sacculus according to dissimilar patients.
Description of drawings
Fig. 1 is the structural representation of this utility model embodiment one.
The specific embodiment
Below in conjunction with accompanying drawing embodiment of the present utility model is further described.
Embodiment one
With reference to Fig. 1: a kind of anti-infiltration catheter, comprise conduit 1, the head of described conduit 1 is provided with urine filling mouth 2, afterbody is provided with the mouth 3 of urinating, head one side of described conduit 1 also is provided with the air bag 4 that is stuck in the internal urethral orifice upper end, described air bag 4 is connected with gas guide nozzle 6 by airway 5, and the bottom towards the mouth 3 of urinating of described air bag 4 presents the taper that cooperates with internal urethral orifice.
In the present embodiment, described airway 5 is arranged on the tube wall inside of described conduit 1.
Present embodiment is a double lumen catheter, and described air bag 4 connects an airway 5.
Present embodiment is by 5 pairs of air bags of gas guide nozzle 4 inflation, and the conical design of air bag 4 bottoms makes air bag 4 to fit tightly with internal urethral orifice, thereby prevents that urine from oozing out.During use, urethral catheterization technology is routinely operated, and after definite air bag entered bladder, the pumpback catheter was combined closely air bag and internal urethral orifice gently.In the reality, can produce the catheter that has the different model sacculus according to dissimilar patients.
Embodiment two
The difference of present embodiment and embodiment two is: present embodiment is a three-cavity catheter, and described air bag connects two airways simultaneously.Other structures and the embodiment one of present embodiment are identical.
Embodiment three
The difference of present embodiment and embodiment one is: described airway pastes the tube wall outside at described conduit.Other structures and the embodiment one of present embodiment are identical.
The described content of this description embodiment only is enumerating the way of realization of utility model design; protection domain of the present utility model should not be regarded as only limiting to the concrete form that embodiment states, protection domain of the present utility model also reach in those skilled in the art according to this utility model design the equivalent technologies means that can expect.
