Description

Catheter for female

Technical field

The present invention relates to a kind of medical equipment more particularly to a kind of catheter for female.

Background technique

Catheter be with pipeline made of natural rubber, silicon rubber or polyvinyl chloride (PVC), can be through being per urethram inserted into wing Guang comes out so as to drainage of urine, after catheter is inserted into bladder, has the fixed catheter of an air bag to stay in wing close to catheter head end In Guang, so that intravesical urine be discharged.

Summary of the invention

It is an object of the invention to overcome the deficiencies in the prior art, adapt to reality and need, provide a kind of novel in structural design, Catheter for female easy to use.

In order to achieve the object of the present invention, the technical scheme adopted by the invention is as follows:

Design a kind of catheter for female, including insertion tube；The insertion tube includes the sequentially connected front tube of end head and the tail With rear pipe, front and rear tube is closed in junction, the front opening of front tube, further includes an enclosed flexible pocket, and flexible pocket will The junction of front and rear tube surrounds, and the periphery of flexible pocket is equipped with an enclosed air bag, closed between air bag and flexible pocket Filled with gas in region；Several are offered on preceding tube wall in flexible pocket flows backwards hole, the rear pipe in flexible pocket Conduction hole, deflector hole and conduction hole is offered on tube wall to be connected to by flexible pocket interior zone.

Preferably, filling is flexible every bacterium filler in the flexible pocket.

Preferably, it is described it is flexible every bacterium filler be medical cotton.

Preferably, the flexibility is located at the upside in flexible pocket every bacterium filler and is enclosed in the periphery of deflector hole.

Preferably, the flexibility is located at the downside in flexible pocket every bacterium filler and is enclosed in the periphery of conduction hole.

Preferably, the superficies of the air bag are equipped with several spaced pits.

Preferably, the front end surface of the front tube is inclined-plane.

The beneficial effects of the present invention are:

Front and rear tube can be connected to and be isolated by flexible pocket in use, not by its novel in structural design of the design The purpose that isolation may be implemented when urination by this flexible pocket avoids the bacterium in insertion tube from entering in bladder by front tube to wing Guang causes to infect.

Fig. 3 is the air bag cross section structure schematic diagram in the present invention；

In figure: 1. insertion tubes;2. flexible pocket;3. the front end of front tube;It is managed after 4.;5. front tube;6. the connection of front and rear tube Place;7. conduction hole;8. flowing backwards hole;9. flexibility is every bacterium filler;10. pit;11. air bag.

Specific embodiment

Present invention will be further explained below with reference to the attached drawings and examples:

Embodiment 1: a kind of catheter for female, referring to Fig. 1 to Fig. 3；Including insertion tube 1；The insertion in the design Pipe 1 includes that the sequentially connected front tube 5 of end head and the tail and rear pipe 4, front tube 5 and rear pipe 4 are closed in junction.

Further, the front end 3 of the front tube in the design is open, in order to which front tube to be inserted into urethra, in the design The front tube 3 end face of front end be inclined-plane.

Further, the design it further include an enclosed flexible pocket 2, flexible pocket 2 is by the connection of front tube 5 and rear pipe 4 Place surrounds, meanwhile, the periphery of the flexible pocket 2 is equipped with an enclosed air bag 11, the citadel between air bag 11 and flexible pocket 2 Filled with gas in domain.

Further, several are offered on 5 tube wall of front tube in flexible pocket 11 and flows backwards hole 8, are located in flexible pocket 2 4 tube wall of rear pipe on offer conduction hole 7, deflector hole and conduction hole and be connected to by flexible pocket interior zone.

Further, also filled in the flexible pocket 11 flexible every bacterium filler 9, the flexibility is every bacterium filler 9 For medical cotton；Specifically, the flexibility is located at the upside in flexible pocket every bacterium filler and is enclosed in periphery or the institute of deflector hole Flexibility is stated to be located at the downside in flexible pocket every bacterium filler and be enclosed in the periphery of conduction hole.

Further, this society is equipped with several spaced pits 10 also on the superficies of the air bag 11, Through this pit 10 when air bag is entered in bladder by urethra, shrinkage pool can reduce the frictional force of air bag and skin, improve Comfort and convenience when use.

The design is in use, and front tube is entered in bladder by urethra, at this point, its air bag can be completely into bladder In, also can by air bag and portion rested in upper urethral orifice with lower portion, at this point, the shrinkage pool on its air bag may be implemented to urethra Effective sealing of mouth avoids urine from omitting the generation of phenomenon.

When not urinating, no pressure in flexible pocket, flexible pocket attaches front tube, the setting of rear tube wall, at this point, front tube is with after Pipe is isolated by flexible every bacterium filler or flexible pocket, and the bacterium in down tube is avoided to enter in bladder；And works as in bladder and have urine When liquid, urine is entered in front tube by the front opening of front tube, and then urine will be flexible by the gravity of itself in front tube Capsule squeezes outward, and then urine is downwardly by flowing backwards hole discharge to the conduction hole of lower section, and pipe can be discharged after passing through later, In aforesaid operations, due to there being the gas of certain pressure in air bag, at this point, its flexible pocket need to can just be incited somebody to action by a certain amount of urine It is jacked up, that is to say, that can be just discharged by this catheter when the retention of intravesical urine has a certain amount of, be passed through this design Catheter can also carry out patient to suppress urine practice, facilitate the reply of controlled micturition function.

What the embodiment of the present invention was announced is preferred embodiment, and however, it is not limited to this, the ordinary skill people of this field Member, easily according to above-described embodiment, understands spirit of the invention, and make different amplification and variation, but as long as not departing from this The spirit of invention, all within the scope of the present invention.
