Description
Technical field
The utility model belongs to medical instruments field, and in particular to a kind of catheter.
Background technology
Catheter, it is with natural rubber, silicon rubber or polyvinyl chloride（PVC）Manufactured pipeline, can be through per urethram inserting
Bladder comes out so as to drainage of urine, after catheter insertion bladder, has an air bag close to catheter head end（Also referred to as water pocket）
Fixed catheter is stayed in bladder, and should not be deviate from, and drainage tube connection urinal collects urine.In some urethras or prostate disease
The situation of urethral catheterization failure often occurs because its bladder anatomical structure is abnormal in the patient of disease.In order to improve urethral catheterization success rate, need
Catheter is guided to insert bladder using guiding seal wire, its operation difficulty is big, cumbersome.And the air bag of catheter is fixed at present
（Or water pocket）It is a projection expanded in unaerated or water-filling state, the smooth degree of insertion can be influenceed in catheterization procedure,
And after use, after air bag is exhausted, air bag is big compared with initial state variable, can increase the pain of patient when extracting catheter,
Even cause urethral injury.
Utility model content
The purpose of this utility model is to overcome above-mentioned technological deficiency, there is provided one kind insertion is convenient, during intubation or tube drawing
The not catheter of easy damaged urethra.
The utility model to achieve these goals, adopts the following technical scheme that：
A kind of catheter, including for stretching into the head inside bladder and being placed in the afterbody in the external world, the head front end
The guide portion that a diameter is less than urethral catheterization pipe diameter is provided with, multi-turn original state is distributed with catheter body around one section of head
Cave inward, inflate the air bag group expanded outside backward body, the air bag group is connected by gas ducting and extraneous gas-charging connection
Connect, there is drainage channel in catheter main body, the drainage channel end is provided with connector, and drainage channel front end two side is symmetrically set
It is equipped with conduction hole.
The air bag group quantity is 3-6 groups, and every group of air bag quantity 4-6 is individual.
The main body of the guide portion is made up of resin material, coated lubricant coating outside resin.
The connector caliber becomes larger, can Bag for collecting urine or crossover sub, the crossover sub is three-way connection, master connect
Head connects the connector of catheter, and two branch joints connect syringe connection tube, transfusion utensil connecting pipe respectively, and major joint is justified for reducing
Mesa-shaped joint, there are multiple annular ridges thereon.
The beneficial effects of the utility model are can be entered when urethral catheterization tube head is provided with guide portion in intubation using guide portion
Row guiding, without guide wire, convenient operation, add the success rate that urethral catheterization operates.The air bag that catheter is fixed is adopted
With the structure expanded after initially caving in, inflating, it can effectively reduce intubation, tube drawing and using influence of the process to user, subtract
Light patient suffering.
Brief description of the drawings
Fig. 1 structural representations of the present utility model（Air bag unaerated state）.
Fig. 2 structural representations of the present utility model（Inflated condition）.
The structural representation of same air bag group after Fig. 3 inflations.
In figure, 1 guide portion, 2 conduction holes, 3 air bag groups, 4 gas ductings, 5 drainage channels, 6 gas-charging connections, 7 major joints, 8,
11 sealing sheaths, 9 syringe connection tubes, 10 transfusion utensil connecting pipes, 12 connectors.
Embodiment
As shown in Figure 1-Figure 3, catheter of the present utility model, including for stretching into the head inside bladder and being placed in outer
The afterbody on boundary.Bladder is inserted in order to facilitate catheter, it is straight less than catheter that a diameter is provided with the head front end of catheter
The guide portion 1 in footpath, the length of guide portion 1 are inserted embedded in the front end of urethral catheterization tube head in 50mm or so, its rear end.Material can use
Resin, lubricant coating is coated to outside resin, guarantee lubricates during insertion, and friction is small.Guide portion 1 can also use combined type
Structure, its bone core ability metal material such as stainless steel material, metal is covering resin or plastics.
In order to change the air bag of the fixed catheter of tradition（Water pocket）Protuberance is extruded urethra, is damaged in intubation and tube drawing
The problem of urethra, the utility model become air vesicle structure, multiple air bag groups 3, and the air bag group 3 surrounds one section of head catheter
Body is distributed, and its original state caves inward（Shown in Fig. 1）, expand outside the backward body of inflation（As shown in Figure 2）, air bag group 3 is logical
The gas-charging connection 6 that feed channel 4 is overcharged with the external world is connected.The quantity of air bag group 3 is 3-6 groups, and every group of air bag quantity 4-6 is individual, this implementation
It is 5 groups that example, which illustrates air bag group, every group of structure for having 6 ballonets.
There is drainage channel 5 in catheter main body, the end of drainage channel 5 is provided with connector 12, the front end two of drainage channel 5
Sidewall symmetry is provided with conduction hole 2.The caliber of connector 12 becomes larger, can Bag for collecting urine or crossover sub.The present embodiment illustrates
A kind of crossover sub, the crossover sub are three-way connection, and major joint 7 connects the connector 12 of catheter, two branch joint difference
Syringe connection tube 9, transfusion utensil connecting pipe 10 are connect, major joint 12 is reducing round platform straight coupling, there are multiple annular ridges thereon.Connect
Sealing sheath 8,11 is provided with outside syringe connection tube 9, transfusion utensil connecting pipe 10.
In use, under the guiding function of guide portion 1, catheter is inserted into bladder, by gas-charging connection 6 to air bag group 3
Middle inflation, the air bag group 3 caved in outwards expand, catheter are fixed in bladder, and urine enters drainage channel by conduction hole 2
It is introduced into 5 in urinal.When needing to extract catheter, from the gas bleeding of gas-charging connection 6 so that the air bag retraction of air bag group 3, retraction
Air bag afterwards can be equal with urethral catheterization tube wall, and extra resistance will not be produced to tube drawing, mitigates the stimulation to urethra.Needing to rush
When washing bladder or irrigation of bladder administration, crossover sub can be applied, selects transfusion device or syringe irrigation, convenient operation.
