Specific embodiment
With reference to the accompanying drawing and the preferred embodiment specific embodiment that the present invention will be described in detail.
A kind of self-loopa bladder irrigator as shown in Figure 1:, including flushing pipe, flushing pipe is made of outer tube 1 and inner tube 2, interior
It is linked together between pipe 2 and outer tube 1 by axial equally distributed multiple cradling pieces 3, the lumen of inner tube 2 is flushing liquor feed liquor
Channel, the annular chamber between inner tube 2 and outer tube 1 is flushing liquor apocenosis passage, and the tail end of inner tube 2 is provided with syringe connector,
The tail end side wall of outer tube 1 is provided with leakage fluid dram, continues to inject flushing liquor into bladder by the flushing liquor feed pathway of inner tube 2,
Flushing liquor can flow through the flushing liquor apocenosis passage discharge between inner tube 2 and outer tube 1, reach and follow certainly after cystanastrophe rolling stops
The effect of ring.Its axis is provided with interlocking bar 4 in inner tube 2, interlocking bar 4 is supported by two bearings, the outer ring of bearing
It is fixedly connected by support bar with inner tube 2, interlocking bar 4 passes through the inner ring of bearing and is fixedly connected with inner ring, and interlocking bar 4 can lead to
It crosses the two bearings and realizes and rotated in inner tube 2 again, the lower end of interlocking bar 4 is arranged with active twisted blade 5, interlocking bar 4
Upper end, which stretches out inner tube 2 and is arranged with extravasated blood, breaks up twisted blade 6, active twisted blade 5 and the torsion for having extravasated blood to break up twisted blade 6
Bent contrary, the purpose being arranged in this way is to make the flushing liquor of reflux when flowing through extravasated blood and breaing up twisted blade 6, is broken up to extravasated blood
Twisted blade 6 equally generates rotary thrust, and extravasated blood is made to break up twisted blade 6 with stronger rotates effe, active twisted blade 5
Effect be that when flushing liquor flows in the lumen of inner tube 2, will drive for driving interlocking bar 4 to be rotated and actively distort leaf
Piece 5 rotates, and then interlocking bar 4 is driven to rotate, and the effect that extravasated blood breaks up twisted blade 6 is that the clot that will be carried secretly in flushing liquor is beaten
Dissipate, be discharged from flushing liquor apocenosis passage convenient for clot, interlocking bar 4 rotate while will drive extravasated blood break up twisted blade 6 into
Row rotation, keeps clot broken when flowing through flushing liquor apocenosis passage mouth, can smoothly enter into flushing liquor apocenosis passage, wing is finally discharged
Guang.
As shown in Figure 2: in the traveling process of urethra, head end causes to damage flushing pipe to urethral canal inner wall in order to prevent,
The crimping 7 for the extension that concaves is set in the head end of outer tube 1, which is not only avoided that the loss to urethra, additionally it is possible to by extravasated blood
Twisted blade 6 is broken up partially hide.
It is as shown in Figure 3: in order to make active twisted blade 5 generate biggish rotary force, to be arranged with 5 in the lower end of interlocking bar 4
A active twisted blade 5, active twisted blade 5 are the biggish wealthy palm twisted blade of area, and wealthy palm twisted blade refers to blade
Shape helps to create stronger rotation close to round or ellipse, the blade of this shape.
It is as shown in Figure 4: in order to make extravasated blood break up twisted blade 6 with preferably effect is smashed, in the upper end cap of interlocking bar 4
Twisted blade 6 is broken up equipped with 7 extravasated blood, extravasated blood breaks up the willow leaf twisted blade that twisted blade 6 is elongate form, and extravasated blood breaks up torsion
Bent 6 outer rim of blade has the cutting edge for cutting clot, and the willow leaf twisted blade 6 of elongate form helps to provide cutting frequency,
Intravesical clot can sufficiently be smashed.
The application method of self-loopa bladder irrigator of the present invention is as follows:
Before use, carrying out disinfection operation to bladder irrigator, urethra is then protruded by the urethral orifice of patient in the end of flushing pipe
It is interior, and advance along urethra, the length protruded into according to flushing pipe judges that the end of flushing pipe has entered and stops row in bladder
Into will extract the syringe for having flushing liquor and be connected to the tail end of inner tube, and drain pipe will be connected on the leakage fluid dram of outer tube, firmly
Flushing liquor in syringe is injected inner tube, and flows through inner tube and enter in bladder by the push rod for pushing piston rod, and flushing liquor is in inner tube
It will drive the rotation of active twisted blade during flowing, and then drive interlocking bar rotation, it is final that extravasated blood is driven to break up distortion leaf
Piece rotation, since inner tube is continuing to inject flushing liquor into bladder, flushing liquor can be along inner tube and outer tube after stopping in bladder
Between annular chamber flow out (as shown in Figure 5), and the extravasated blood that can be rotated at the port for flowing through annular chamber breaks up distortion leaf
Piece is smashed, and to be smoothly discharged, when the liquid when be discharged in drain pipe does not carry clot secretly, that is, is completed the flushing work of bladder, will be rushed
Pipe is washed to extract from urethra.
The above described is only a preferred embodiment of the present invention, be not intended to limit the present invention in any form, though
So the present invention has been disclosed as a preferred embodiment, and however, it is not intended to limit the invention, any technology people for being familiar with this profession
Member, without departing from the scope of the present invention, when the technology contents using the disclosure above make a little change or modification
It is right according to the technical essence of the invention for the equivalent embodiment of equivalent variations, but without departing from the technical solutions of the present invention
Any simple modification, equivalent change and modification made by above embodiments, all of which are still within the scope of the technical scheme of the invention.
