Description
Technical field
The present invention relates to the field of medical instrument technology, and more particularly, the present invention relates to a kind of catheters.
Background technology
Urethral catheterization is clinically common one of medical care precess, suitable for having because lower urinary tract obstruction or neural source bladder etc. are many
The retention of urine caused by reason, urethral catheterization behaviour is also applied to rescue urgent patient, peri-operation period prepares, intravesical drug is perfused or bladder
Situations such as flushing.Catheter is equally applicable for the drainages such as bladder stoma, renal plevis fistulization use.
The catheter clinically applied at present has double cavity structure and three-cavity structure, and the catheter of wherein two-chamber includes that urethral catheterization is logical
Road and waterflood path, catheter front are equipped with the sacculus being connected with waterflood path, and the catheter in front of sacculus is equipped with
Urine import, catheter are fixedly arranged at the front end with bullet-headed end；The catheter of three chambers further includes irrigation channel, sacculus front end
Catheter is equipped with the opening being connected with irrigation channel.But catheter and bullet in front of these existing catheter sacculus
The total length of capitiform end has 2-3 ㎝, as shown in Figure 1 (dotted line is bladder inner wall).(Urology Surgery doctor passes through wing to clinical discovery
Guang spectroscopy) traditional urinary catheter indwelling is more than 24 hours, will in fundus of bladder, traditional touched range of urinary catheter head formation limitation
The different degrees of inflammatory of mucous membrane of urinary bladder changes, and occurrence probability is almost 100%, when urinary catheter indwelling is more than 1 week, in Guang bottom urinary catheter head
Inflammatory hyperplasia, polyp, folliculus etc. are formed in region in one's power and with surface ulceration and different degrees of bleeding, indwelling is more than 1 month
When, there is inflammatory hyperplasia tissue surface or even calcification and clot occurs clinical discovery few patients' Guang bottom urinary catheter head in range in one's power.
Clinic infers that Preserving time tradition urinary catheter may have certain canceration risk.And pain and cystospasm in patients with catheterization Guang
Equal malaise symptoms are in this positive correlation.Traditional urinary catheter has Iatrogenic injury drawback.
Chinese invention patent application 201610823743.8 discloses a kind of catheter, and bullet is set in pipeline sacculus front
The high pressure water pocket of capitiform, sets the high pressure water water injection pipe being connected with high pressure water pocket in tube body, the front end of high pressure water water injection pipe with it is high
Pressure water pocket is fixed together, and by the intracapsular injection water of high pressure water, making high pressure water pocket be expanded into bullet-headed, increases urinary catheter and prolongs urine
Road or the compliance of fistulization oral implantation, after tube body per urethra enters in bladder, the intracapsular water of discharge high pressure water is drawn high outward
Water water injection pipe is pressed, high pressure water pocket is pulled out outside catheter, urine is entered from the front opening of catheter in tube body, is entered back into
In urinal, stimulation bladder is avoided, but there are certain risks for this method, if during being sent into catheter, high pressure water
Capsule damages, and cannot not only increase the compliance of catheter implantation, can also cause to damage to bladder.In addition it is also needed using high pressure water pocket
Water is injected thereto so that catheter is complicated and cumbersome.

In the present embodiment, there is certain curvature radian in 110 front end of the tube body, further avoids leading when tube body 110 is implanted into
The stimulation of 120 pairs of bladder inner walls of leader.Preferably, 110 front end of the tube body has close with 120 hemisphere one end of the target seeker
As curvature, the stimulation to bladder inner wall can be preferably reduced, certainly, when 110 front end of the tube body and the target seeker 120
When hemisphere one end is continuous cambered surface, the stimulation to bladder inner wall is minimum.
Operation principle：
When being implanted into catheter, when driving the target seeker to be axially moved to tube body front end along the tube body by connecting core
(through slot can pass through block for target seeker) limits the target seeker by clamping device and continues along the tube body axis
To travelling forward, rotatable connection core makes target seeker rotate so that through slot is staggered completely with block, so that block limits target seeker
Along the tube body axially rearward movement, increases the compliance that urinary catheter prolongs urethra or fistulization oral implantation, wait for that tube body per urethra enters
After in bladder, the water filling into sacculus from waterflood path makes balloon inflation position catheter, takes away clamping device, is rotatably connected
Core rotates target seeker in turn so that through slot is directed at the block, extracts connection core out axially backward along the tube body and then extracts out
Target seeker, urine are entered in tube body from the front opening of catheter, are entered back into urinal.Need to rinse then uses three chambers
Structure includes irrigation channel, injects flushing water into bladder by irrigation channel, can rinse the substances such as intravesical clot
Get off and is flowed into urinal along tube body.
Catheter of the present invention is provided with target seeker in tube body front end, and the target seeker can be along the tube body axis
To movement, without using high pressure water pocket, and target seeker can facilitate, safety is withdrawn from out of tube body, avoid using high pressure water pocket
The risk that water pocket is damaged in the process decreases the process to high pressure water pocket water-filling so that and catheter overall structure is simple,
It is easy to operate.In the target seeker of tube body front end setting, increase the compliance that urinary catheter prolongs urethra or fistulization oral implantation, due to catheter
Target seeker is taken out after implantation, is also minimized the Accessory injury that existing urinary catheter generates bladder inner wall mucous membrane, in addition target seeker
Front end be hemisphere, both facilitated the implantation of catheter, and also avoided the stimulation to bladder inner wall, and solved renal plevis balloon type and make
Fistula is difficult to the problem of being implanted into.
