Abstract
Catheter is related to medical instruments field.Mainly solve existing catheter injured patient bladder inwall mucous membrane the problems such as and design.It includes being provided with waterflood path in body, body, and waterflood path rear end is provided with the first valve, and body front portion is provided with sacculus, and the sacculus is connected with waterflood path front end；It is characterized in that：Bullet-headed high pressure water pocket is set in sacculus front portion, high pressure water pocket rear portion is provided with plug, described plug is inserted in body front end, i.e. plug outer wall is contacted with body front inner wall, the water under high pressure water injection pipe being connected with high pressure water pocket is set in body, the front end of water under high pressure water injection pipe is fixed together with high pressure water pocket, and the rear end of the water under high pressure waterflood path is provided with the second valve.Irrigation channel is set in body, the opening of the irrigation channel front end is positioned at the front of sacculus.Advantage is that the Accessory injury for producing existing urinary catheter to bladder inwall mucous membrane is minimized.
Description
Technical field：
The utility model is related to medical instruments field, is specifically related to a kind of catheter.
Background technology：
Urethral catheterization is one of clinically common medical care precess, it is adaptable to caused by lower urinary tract obstruction or neural source bladder etc.
The retention of urine, urethral catheterization behaviour is also applied to rescue urgent patient, is the feelings such as average of operation periods preparation, intravesical drug perfusion or bladder irrigation
Condition.
The catheter clinically applied has double cavity structure and three-cavity structure at present, and wherein the catheter of two-chamber includes urethral catheterization
Passage and waterflood path, catheter front portion are set provided with the sacculus being connected with waterflood path on the catheter in front of sacculus
There is urine import, catheter is fixedly arranged at the front end with bullet-headed termination；The catheter of three chambers also includes irrigation channel, sacculus front end
Catheter be provided with the opening that is connected with irrigation channel.But catheter and son in front of these existing catheter sacculus
The total length of bullet-shaped termination has 2-3 ㎝, and termination and bladder inwall mucosal contact, cause patient when patient uses in the short time
The different degrees of change of bladder inwall mucosal inflammatory, hyperplasia, ulceration, bleeding etc., stay plant to cause the extensive inflammatory of mucous membrane for a long time
Change, some patientss have more serious bladder irritation phenomenon, result even in cystospasm.
It is clinically serious for bladder stoma patient, irritation sign of bladder and renal plevis balloon type stoma is due to Endless
Person, which can give, stays plant to mitigate symptom, but due to stoma front end Endless, it is impossible to it is implanted into along urethra.
The content of the invention：
Technical problem to be solved in the utility model, which is to provide, a kind of can be down to urinary catheter to the Accessory injury of mucous membrane of urinary bladder
Catheter that is minimum and being implanted into along urethra.
What above-mentioned purpose was realized in：It includes body, is provided with waterflood path in body, and waterflood path rear end is provided with the
One valve, body front portion is provided with sacculus, and the sacculus is connected with waterflood path front end；It is characterized in that：Son is set in sacculus front portion
Bullet shaped high pressure water pocket, high pressure water pocket rear portion is provided with plug, and described plug is inserted in body front end, i.e. plug outer wall and pipe
Body front inner wall is contacted, and the water under high pressure water injection pipe being connected with high pressure water pocket, front end and the height of water under high pressure water injection pipe are set in body
Pressure water pocket is fixed together, and the rear end of the water under high pressure waterflood path is provided with the second valve.Body front end is urine import, body
Rear end is connected with urinal.
Irrigation channel can be also set in body, the opening of the irrigation channel front end is positioned at the front of sacculus.
The utility model has the advantages that：Make high pressure to the intracapsular injection water under high pressure of water under high pressure through water under high pressure water injection pipe during implantation
Water pocket be expanded into it is bullet-headed, increase urinary catheter prolong urethra or fistulization oral implantation compliance, treat that body per urethra enters bladder
After interior, the water filling into sacculus from waterflood path makes sacculus expansion position catheter, and the intracapsular water of discharge water under high pressure is pulled outwardly
Water under high pressure water injection pipe, high pressure water pocket is pulled out outside catheter, urine is entered in body from the front opening of catheter, is entered back into
Into urinal.Due to taking out high pressure water pocket after implantation, so the Accessory injury that can produce existing urinary catheter to bladder inwall mucous membrane
Minimize, additionally, due in implantation, to the intracapsular water filling of water under high pressure, the urinary catheter possesses the implantation compliance of existing urinary catheter well,
So solving the problem of renal plevis balloon type stoma is difficult to implantation.
Brief description of the drawings：
Fig. 1 is structural representation of the present utility model；
Fig. 2 is Fig. 1 A-A views.
Embodiment：
Reference picture 1,2, it includes being provided with waterflood path 2 in body 1, body, and waterflood path rear end is provided with the first valve 3,
Body front portion is provided with sacculus 4, and the sacculus is connected with waterflood path front end；It is characterized in that：Set bullet-headed in sacculus front portion
High pressure water pocket 5, high pressure water pocket rear portion is provided with plug 6, and described plug is inserted in body front end, i.e., plug outer wall with before body
Hold in inwall contact, body and set the water under high pressure water injection pipe 7 being connected with high pressure water pocket, the front end of water under high pressure water injection pipe and water under high pressure
Capsule is fixed together, and the rear end of the water under high pressure waterflood path is provided with the second valve 8.Body front end is urine import, after body
End is connected with urinal.
Irrigation channel 9 can be also set in body, the opening of the irrigation channel front end is positioned at the front of sacculus.
