Description
Technical field
The catheter combination containing seal wire that the present invention relates to a kind of.
Background technique
Urethral catheterization is clinically common one of medical care precess, the retention of urine caused by being suitable for because of lower urinary tract obstruction, urethral catheterization behaviour
Situations such as being also applied to rescue urgent patient, general anesthesia Preoperative Method, intravesical drug perfusion or bladder irrigation.But various
When patient's (such as ankylurethria, serious hyperplasia of prostate, urethral injury) of urethra or prostatic disorders needs urethral catheterization, due to suffering from
Person's bladder anatomical structure is abnormal, the case where urethral catheterization failure often occurs.
However, for the processing mode of the patient of urethral catheterization difficulty, the following defects and deficiencies exist in the prior art:
Firstly, clinician such as encounters the patient of urethral catheterization difficulty, need to look for seal wire again when carrying out urethral catheterization to patient,
Delay clinical catheterization opportunity.
Secondly, the seal wire that clinician uses generally is superslide seal wire, not designed for urethral catheterization operation, price is high
It is expensive.
In addition, being to guide the length of seal wire generally longer in clinical manipulation, it is unfavorable for doctor's operation.
Furthermore it when clinician carries out aperture to catheter top, is easy to puncture urethral catheterization tube airbag, catheter is caused to be fixed
It is bad, the complication such as catheter slippage.
Chinese patent literature CN105361102A, the applying date 20151014, patent name are as follows: a kind of urethral catheterization of built-in seal wire
Pipe discloses a kind of catheter of built-in seal wire, including urethral catheterization tube body and sets seal wire in the inner, the front end of the urethral catheterization tube body
Equipped with a contractile sacculus, it is equipped with endless drive loop in the middle part of the sacculus inner wall, runs through on the sacculus and offers at least
One urethral catheterization hole, the middle part of the driving band are equipped with limit hole, and the front end of the seal wire is equipped with spherical top, is located at spherical top
Lower section be equipped with driving bulge loop, when the spherical top of the seal wire is along urethral catheterization tube cavity upward sliding to inner wall top, institute
Stating driving bulge loop can offset with driving band and it is driven to move upwards, and the sacculus being correspondingly connected with the driving band is inside therewith
It shrinks.
Aforementioned patents disclose a kind of catheters of built-in seal wire, drive it to enter bladder seal wire insertion urethral catheterization tube body,
When the spherical top of its front end is along urethral catheterization tube cavity upward sliding to inner wall top, driving bulge loop can offset with driving band and band
It moves it to move upwards, sacculus to contract, will not hinder urethral catheterization tube body to enter bladder therewith；When urethral catheterization tube body can smoothly enter into bladder
Afterwards, seal wire is extracted, sacculus can restore under itself and the elastic deformation effect of driving band, can effectively replace the fixed urethral catheterization of air bag
Tube body.But in the specific implementation, at high cost by the way of seal wire+urinary catheter, income is small, and needs seal wire and catheter one
Insertion is played, seal wire is fixedly connected with catheter, and stays in the body seal wire for a long time, causes patient Linchuan uncomfortable or secondary
Infection.
