Description

Band is observed the catheter of air bag

Technical field

This utility model relates to a kind of catheter, belongs to medical auxiliary apparatus.

Background technology

Catheter is the pipeline made from natural rubber, silicone rubber or polrvinyl chloride (PVC), can be through per urethram inserting bladder in case drainage of urine out.It is the conventional medical auxiliary apparatus apparatus that hospital generally adopts.

Initial what use is ordinary urethral catheter, often the catheter self falling can occur, and reach the purpose for the treatment of expection, and this has not only incured loss through delay treatment opportunity, has increased patient's misery and the chance of urinary tract infection, has increased unnecessary workload to medical personnel again.Generation for fear of above-mentioned phenomenon, after 2000, the whole nation all begins to use instead the gasbag-type catheter, obtained satisfied effect, its basic structure is to be provided with thinner thin layer outside the circumference of catheter front end certain position, and this thin layer is in closed state, just be connected to the inflation inlet of catheter end by a tubule road, this tubule road is arranged in the wall of catheter, during use, after the catheter front end was deep into intravesical, this thin layer also should be in intravesical in theory, with syringe toward inflation inlet (check valve is arranged in the inflation inlet) injecting gas or liquid, under the effect of pressure, gas or liquid will enter in the thin layer from the tubule road, and keep this state after expanding into an air bag, this air bag is positioned at intravesical, and its effect is to prevent the catheter landing.During this period, intravesical urine will be collected by Bag for collecting urine behind drippage in the pipeline of catheter.

But some problems also appear in the gasbag-type catheter in clinical use: because nursing staff's insertion depth when operation is inadequate, an air bag part is in urethra, a part is namely given the catheter gasbag pressurizes at intravesical, thereby causes airbag inflation damage urethra, has caused patient's very big misery.More seriously this very easily makes doctor's mistaken diagnosis.

Present stage, the insertion of catheter is entirely with nursing staff's experience and sensation.The present situation of doctor-patient relationship anxiety, the nursing staff that this more makes the nursing staff especially be lacking in experience is bearing greatly pressure psychologically.

In order to address this problem, the technical staff has also proposed some schemes, indicated scale (CN201120275904.7) such as the 3rd Affiliated Hospital of Third Military Medical University at catheter, Central-South hospital of Wuhan University is provided with Pressure gauge (CN201120070501.9) at inflation inlet, but these means are not best solutions.

Summary of the invention

The purpose of this utility model provides a kind of catheter with observing air bag to remedy the deficiency of prior art.

This utility model for realizing the technical scheme that purpose adopts is: band is observed the catheter of air bag, comprise the catheter body, the urine pipeline is arranged in the catheter body, catheter body front end circumference has upper gasbag outward, upper gasbag is connected in arm by the tubule road, and the arm end is inflation inlet, and the tubule road is positioned on the wall of catheter body, it is characterized in that: catheter body tip circumference is outside equipped with the observation air bag, observes air bag and tubule road and communicates; The observation air bag perhaps is set outside the Zhi Guanbi circumference.

Optimize, upper gasbag is identical with wall thickness with the radial dimension of observing air bag.

Good effect of the present utility model is: make simply, the material of upper gasbag, technique etc. all belong to existing mature technology, and that manufacturing of observing air bag is just without any difficulty; Use directly perceived simple: the nursing staff can be intuitively according to the observation the state of air bag just can infer easily upper gasbag at intravesical state, thereby alleviated greatly patient's misery, also avoided mistaken diagnosis phenomenon in the past; With low cost: because catheter is disposable products, expensive loaded down with trivial details design can increase patient's burden, and we have reduced doctor-patient dispute by succinct practical product, can obtain medical personnel and patient's welcome.

Fig. 2 is the A-A generalized section of Fig. 1;

Fig. 3 is the sketch map of another embodiment.

The specific embodiment

Embodiment 1:

In the drawings: 1 is the catheter body, and 2 is the urine pipeline, and 3 is upper gasbag, and 4 is the tubule road, and 5 is arm, and 6 is inflation inlet, and 7 for observing air bag.

During use, operational approach is inserted catheter body 1 routinely, and its front end arrives intravesical by urethra, and urine is by urine pipeline 2 drippages, and at this moment, catheter body 1 end, observation air bag 7, arm 5 and inflation inlet 6 are all outside health.

Now just in two kinds of situation: upper gasbag 3 puts in place and situation not in place, and the below narrates respectively.

Situation puts in place: the nursing staff is with quantitative (40ml) liquid or gas in the needle tubing, inject by inflation inlet 6, gas or liquid enter tubule road 4 by arm 5, liquids and gases in the tubule road can enter into to be observed in air bag 7 and the upper gasbag 3, because this environment is in sealing, so pressure will force lower thin observation air bag 7 and upper film layer upper gasbag 3 to expand, because upper gasbag 3 and to observe the size wall thickness of air bag 7 identical and be in the environment of equipressure, so upper gasbag 3 is identical with the degrees of expansion of observing air bag 7, for the nursing staff, naked eyes can see that observation air bag 7 is in normal swelling state and just can judges success of this behavior.

Because the sealing process (check valve belongs to existing known technology) of the check valve in the air-filled pore 6, so that upper gasbag 3 and observation air bag 7 keep swelling state always, just can make the nursing staff can monitor at any time the state of observing air bag 7, thereby infer whether the state that upper gasbag 3 is normal.So just can promptly and accurately judge whether the existence of gas leak phenomenon.

Situation not in place: the nursing staff is according to aforesaid operations, also be with quantitative (40ml) liquid or gas inject, owing to the upper gasbag 3 all or part of urethras that are positioned at this moment, so upper gasbag 3 can be subject to the compressing of urethra when expanding, so, this moment, upper gasbag 3 and observation air bag 7 were not isobaric environment just, so, the nursing staff needs only one and sees that the degrees of expansion of observing air bag 7 is far longer than normal degree, it is defective just can accurately to judge this behavior, also adopt remedial measures immediately thereby stop action, like this, just can any injury not arranged to the patient.

Embodiment 2:

Compare with embodiment 1, difference is that the setting position of observation air bag 7 is different, observes air bag 7 in the present embodiment and is arranged on arm 5 excircles, between observation air bag 7 and arm 5 passage is set, and can realize that the pressure in the arm 5 expand observation air bag 7.
