Abstract
The utility model discloses a catheter which comprises a catheter body, wherein an urine inlet is formed at the front end of the catheter body; an urine outlet is formed at the back end of the catheter body; an urine passage is formed in the catheter body; the urine inlet is communicated with the urine outlet through the urine passage; an air bag is further arranged at the back end of the catheter body; the catheter body is provided with an inner layer body and an outer membrane; an air charging cavity is formed between the inner layer body and the outer membrane; and the air bag is communicated with the air charging cavity. The catheter has low probability of loosing and dropping off during use, and can reduce uncomfortable feeling.
Description
Technical field
This utility model relates to a kind of catheter.
Background technology
Existing catheter is that the front end by body is fixed, and there are the following problems for this structure:
1, fixing not firm, make the easy loose or dislocation of catheter;
2, easily irritate trigone of bladder and mucous membrane of urethra, cause sense of discomfort.
Summary of the invention
Based on this, this utility model is to overcome the defective of prior art, and a kind of catheter is provided, and this utility model is difficult for loose or dislocation in use, reduces sense of discomfort.
Its technical scheme is as follows:
A kind of catheter, comprise body, front end at body is provided with urine filling mouth, rear end at body is provided with urine outlet, forms urethra in body, and urine filling mouth communicates with urine outlet by urethra, also be provided with in the rear end of body and inflate capsule, described body has internal layer body and adventitia, forms inflatable chamber between internal layer body and adventitia, and the capsule of inflating communicates with inflatable chamber.
The below describes further technical scheme:
Described internal layer body is also the mantle shape.
Be formed with junctional membrane between described internal layer body and adventitia.
Described junctional membrane is spirally wrapped around between described internal layer body and adventitia.
Front end at described body is provided with fixation balloon, and this fixation balloon communicates with described inflatable chamber.
The below describes advantage or the principle of aforementioned techniques scheme:
1, the body of this catheter is double-decker, and form betwixt inflatable chamber, before catheter inserted, the air of inflatable chamber was evacuated, pipe diameter diminishes, after catheter inserts, to inflate to inflatable chamber by inflating capsule, adventitia expands and the body external diameter is increased, the adventitia of body and urethra are closely affixed, avoid the body loose or dislocation, also reduced the stimulation to trigone of bladder and mucous membrane of urethra, reduced sense of discomfort.
2, described internal layer body is also the mantle shape, can facilitate the insertion of catheter.
3, be formed with junctional membrane between described internal layer body and adventitia, after junctional membrane is set, be difficult for dislocation between internal layer body and adventitia but movable in can proper range, can better guarantee rigidity and the urethral catheterization effect of body when inflation.
4, described junctional membrane in the shape of a spiral, can protect whole body stressed evenly, the high conformity of whole section body.
5, the front end at described body is provided with fixation balloon, can also reach by this fixation balloon and strengthen fixing effect.

The specific embodiment
The below is elaborated to embodiment of the present utility model:
As shown in Figure 1 and Figure 2, a kind of catheter, comprise body 10, be provided with urine filling mouth 11 at the front end of body 10, be provided with urine outlet 12 in the rear end of body 10, at the interior formation urethra 13 of body 10, urine filling mouth 11 communicates with urine outlet 12 by urethra 13, also is provided with in the rear end of body 10 to inflate capsule 20, and described body 10 has internal layer body 14 and adventitia 15, form inflatable chamber 16 between internal layer body 14 and adventitia 15, the capsule 20 of inflating communicates with inflatable chamber 16.
Wherein, described internal layer body 14 is also the mantle shape, is formed with junctional membrane 17 between described internal layer body 14 and adventitia 15, and described junctional membrane 17 is spirally wrapped around between described internal layer body 14 and adventitia 15.
Front end at described body 10 is provided with fixation balloon 30, and this fixation balloon 30 communicates with described inflatable chamber 16.
The present embodiment has following advantage:
1, the body 10 of this catheter is double-decker, and form betwixt inflatable chamber 16, before catheter inserted, the air of inflatable chamber 16 was evacuated, body 10 diameters diminish, after catheter inserts, to inflate to inflatable chamber 16 by inflating capsule 20, adventitia 15 expands and body 10 external diameters is increased, the adventitia 15 of body 10 is closely affixed with urethra, avoid body 10 loose or dislocations, also reduced the stimulation to trigone of bladder and mucous membrane of urethra, reduced sense of discomfort.
2, described internal layer body 14 is also the mantle shape, can facilitate the insertion of catheter.
3, be formed with junctional membrane 17 between described internal layer body 14 and adventitia 15, after junctional membrane 17 is set, be difficult for dislocation between internal layer body 14 and adventitia 15 but movable in can proper range, can better guarantee rigidity and the urethral catheterization effect of body 10 when inflation.
4, described junctional membrane 17 in the shape of a spiral, can protect whole body 10 stressed evenly, the high conformity of whole section body 10.
5, the front end at described body 10 is provided with fixation balloon 30, can also reach by this fixation balloon 30 and strengthen fixing effect.
The above embodiment has only expressed the specific embodiment of the present utility model, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to this utility model the scope of the claims.Should be pointed out that for the person of ordinary skill of the art, without departing from the concept of the premise utility, can also make some distortion and improvement, these all belong to protection domain of the present utility model.
