Description
Technical field
The utility model relates to the field of medical instrument technology, and more particularly, the utility model relates to a kind of catheters.
Background technique
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 wherein the catheter of 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 greater 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 greater than 1 week, in Guang bottom urinary catheter head
Inflammatory hyperplasia, polyp, folliculus etc. and with surface ulceration and different degrees of bleeding are formed in region in one's power, indwelling is greater 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 utility model patent application 201610823743.8 discloses a kind of catheter, sets in pipeline sacculus front
Bullet-headed high pressure water pocket sets the high pressure water water injection pipe being connected with high pressure water pocket, the front end of high pressure water water injection pipe in tube body
It is fixed together with high pressure water pocket, by being expanded into high pressure water pocket bullet-headed to the intracapsular injection water of high pressure water, increases urinary catheter
The compliance for prolonging urethra or fistulization oral implantation, after tube body per urethra enters in bladder, the intracapsular water of discharge high pressure water, outward
High pressure water water injection pipe to be drawn, high pressure water pocket is pulled out outside catheter, urine enters in tube body from the front opening of catheter, then into
Enter into urinal, avoids stimulation bladder, but there are certain risks for this method, if during being sent into catheter, it is high
Water pocket damage is pressed, the compliance of catheter implantation is not can increase not only, also bladder can be caused to damage.In addition high pressure water pocket is used
It also needs to inject water thereto, so that structure is complicated and cumbersome for catheter.

Working principle:
When being implanted into catheter, when driving the target seeker to be axially moved along the tube body to tube body front end by connection 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, rotation connection core rotates target seeker, 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, entered to tube body per urethra
It after in bladder, is filled the water from waterflood path into sacculus, positions balloon inflation to catheter, take away clamping device, rotation connection
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 described in the utility model is provided with target seeker in tube body front end, and the target seeker can be along the pipe
Body is axially moved, and without using high pressure water pocket, and target seeker can be convenient, safety is withdrawn from out of tube body, avoid using high pressure
The risk that water pocket is damaged during water pocket decreases the process to high pressure water pocket water-filling, so that catheter overall structure
Simply, 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
Target seeker is taken out after catheter implantation, is also minimized the Accessory injury that existing urinary catheter generates bladder inner wall mucous membrane, in addition
The front end of target seeker is hemisphere, had both facilitated the implantation of catheter, and had also avoided the stimulation to bladder inner wall, and had solved renal plevis ball
Bladder type stoma is difficult to the problem of being implanted into.
It is not only in the description and the implementation although the embodiments of the present invention have been disclosed as above
Listed utilization, it can be applied to various fields suitable for the present invention completely, for those skilled in the art,
Other modifications may be easily implemented, therefore without departing from the general concept defined in the claims and the equivalent scope, this reality
It is not limited to specific details and legend shown and described herein with novel.
