Description
Technical field
Drainage wash the present invention relates to secretion behind medical aid field more particularly to a kind of operation on urethra is with leading
Urinary catheter.
Background technology
Urethral catheterization is one of clinically used medical care precess, needs to use in many cases.Catheter is usually used in collecting urine
Liquid and drainage of urine especially in Urology Surgery after urethra, are widely used.Urethra postoperative patient often needs retention catheterization pipe 3 weeks
Left and right, and it is also in the meantime the stage that Postoperative urinary tract wall secretion generates accumulation.Patent of invention (103263719 A of CN) is public
A kind of urethra washing catheter is opened, inside configuration is equipped with drainage cavity, and catheter is equipped with sacculus, urethral catheterization pipe diameter
Suitable with urethra internal diameter, urethra endocrine liquid is not easy to flow, if juice is more sticky, is more easy to accretion.In juice
Enzyme can further break outer tissue, generate damage, while easily cause infection, infect further diffusion, antidromicity can be caused to urinate
Road feel contaminates.If secretion accumulation is excessive, pressure increases between conduit and urethra, may cause the repressive occlusion of catheter, so as to draw
The retention of urine is played, consequence is serious.Although foregoing invention on the tube wall in the middle part of catheter be equipped with rinse micropore, rinse when perpendicular to
Urethra tube wall is rinsed, and when flushing pressure is excessive, easily the urethra suture mouth just through operation is caused to damage, be hung down in addition
It flings and washes the outflow direction for being unable to control urethral secretions, instead it is possible that secretion is caused to be accumulated to urethra depths.
The content of the invention
In order to solve the above technical problem, the present invention provides a kind of catheter, innovation employs pipeline reducing diameter and designs, is non-
The micropore vertically rinsed has respectively reached urethral secretions and has rinsed abundant, undamaged effect.
Its technical solution is as follows：
A kind of catheter, including the closed top in bladder end, water pocket, urine drainage pipeline, flushing pipe, water pocket water injection pipe
Road, catheter tail end, each pipeline on the catheter is not connected and is each provided with entrance, wherein urine drainage pipeline
Entrance is located on the side wall below the closed top in bladder end, and outlet is located at catheter tail end, and the outlet of flushing pipe is located at wing
On side wall below the closed top in Guang end, water pocket is located at flushing pipe outlet and the lower section of urine drainage pipeline entrance, and water passes through
It is arranged in the water pocket water filling inlet connection water pocket filling pipe injection water pocket of urethral catheterization pipe outer wall, annular punching is equipped with below water pocket
Structure and the micropore being located on annular flushing mechanism side wall are washed, which has been divided into two kinds of diameters by catheter
Tube body, wherein close to bladder end diameter be more than urethra tube in diameter；Annular flushing mechanism is connected with flushing pipe, annular
Micropore on flushing mechanism side wall and it is less than 90 ° parallel to the angle between catheter axis.
Further, catheter tail end include removable connector and funnel-form interface, connector be a hollow pipe, one
End is connected with urine drainage pipeline, the other end and funnel-form orifice；Funnel-form interface include interior layer interface and outer layer interface,
Urine drainage exports and flushing liquor entrance, specifically, urine drainage outlet is connected by connector with urine drainage pipeline, rinses
Liquid entrance is connected with flushing pipe, and connector and the internal layer orifice in funnel-form interface, flushing pipe connect with outer layer interface
It is logical.
Further, water pocket water filling inlet and/or flushing liquor entrance are equipped with two panels individual event flap valve.
Further, connector is a shuttle-type hollow pipe.
Further, the entrance of urine drainage pipeline is located at the closed top 1.5-2.5mm in bladder end.
Further, the outlet of flushing pipe is located at the closed top 4.5-5.5mm in bladder end.
Further, water pocket is located at the closed top 7.5-8.5mm in bladder end.
Further, annular flushing mechanism is located at the closed top 14.5-15.5mm in bladder end.
Further, the closed top in bladder end is semicircle, ellipse.
Advantageous effect is：
1. catheter tube body provided by the invention uses variable diameter design, it is big to be inserted into the caliber of bladder with partial, is inserted into urethra
Caliber it is small, make between catheter tube body and urethral wall be equipped with certain gap, be conducive to the discharge of secretion.
2. catheter annular flushing mechanism side wall of the present invention be equipped with equally distributed micropore, and with parallel to catheter pipe
Angle between body axis is less than 90 °：On the one hand liquid can be made, and from urethra bosom to orificium urethrae externum direction, annular is rinsed, and is prevented
Secretion is accumulated to urethra depths, and on the other hand annular oblique angle rinses direction and elongated flushing distance, can be to avoid because of vertical punching
Wash pressure it is excessive cause urethra suture injury of mouth.
3. the present invention can be carried out at the same time bladder irrigation and be rinsed with urethra.Bladder irrigation passage is rinsed with urethra in the present invention
Passage is same passage, be expert at bladder irrigation when, only when flushing pressure is very big, flushing liquor is by annular flushing mechanism
After micropore on side wall goes out decompression, remaining flushing liquor can also continue bladder irrigation behaviour in the case where pressure becomes smaller
Make.At this point, the flushing liquor pressure gone out from urethra annular flushing mechanism side wall is larger, the urethral wall for directly rushing at reparation can be right
Reparation urethra is caused to cause further to damage, the present invention reduces the flushing pressure to urethra using the method that inclined-plane rinses
Power, so as to avoid the adverse consequences that direct flushed zone comes.
4. the present invention is using connector and double wall funnel shape Interface design, can in the case where not influencing urine drainage, into
Row urethra flushing operation, attachment device can effectively close concentric circles two-chamber, interior exocoel separated, and then exercise respective function；
When medicine liquid washing is not required, it may be convenient to disassemble connector and funnel-form interface, reduce patient body and bear
Load.
5. each pipe joint of catheter of the present invention is laid out by the way of dislocation, reduce because traditional catheter is using simultaneously
The medical care precess error that row's trident, four prongs are brought.
