Abstract
Disclosed is a novel catheter for urine drainage, which comprises a bicavity type and a three-cavity type. The bicavity type catheter is formed by a urine tube body 1, a urine drainage end 2 and an air sac passage 3, wherein the urine tube body 1 is provided with a urine drainage hole 4 and a groove 5 parallel to the long shaft of the urine tube, and the cross section of the bicavity catheter is in quincunx. The three-cavity type catheter is provided with a flushing lateral hole besides the above characteristics. Because the front end of the urine tube is equipped with a groove, and contact surfaces and friction force between the urine tube and the urethra inner walls are reduced significantly, thereby reducing urine drainage resistance and decreasing damages on the urethra. Simultaneously, the groove has functions of drain mucous membrane secretion of the urethra, can reduce inflammatory reaction of the urethra mucous membrane, and significantly reduces prospective complications of urine drainage.
Description
Technical field
This utility model belongs to medical field, relates to a kind of novel catheter that is used for urine drainage.
Background technology
Urethral catheterization is one of modal routine operation clinically, and nearly 25% inpatient is owing to a variety of causes needs row urethral catheterization operation.At present clinical general traditional catheter is the pipe shape, and cross section is rounded, and tube wall contacts with mucous membrane of urethra fully, has the gross area friction between tube wall and the mucous membrane of urethra during intubate urethral catheterization and during the indwelling, easily causes mucosa injury and even tears; Put pipe back urethral secretions simultaneously and fail to obtain abundant drain.Generally speaking, urinary system has certain defence capability, when but after inserting traditional catheter, normal defense mechanism just is subjected to negative influence: urinary tract infection inevitably takes place in chemical factors such as the variation of mechanical destruction, inflammatory reaction, mucous membrane of urethra pH value, catheter inside and outside wall biomembrane form, antibacterial grows surely and biological factor, and 30% patient with operation nosocomial infection is relevant with the traditional urinary catheter of indwelling.In addition, the damage of mucous membrane of urethra and inflammatory reaction also can cause serious consequences such as urethral stricture, locking.Though fistulation can significantly reduce urinary tract infection and urethra inflammation, narrow incidence rate on the pubis, belonging to has the wound operation, and certain risk is arranged.
Summary of the invention
The technical problem that solves
For the shortcoming of the circular catheter that overcomes present use, avoid puncture fistula-building on the row pubis simultaneously, the present invention proposes a kind of, novel quincunx catheter of making things convenient for drain urethral secretions less to the mucous membrane of urethra damage.
The realization the technical solution of the utility model is: as being the quincunx urinary catheter of dual-chamber type, catheter body 1 links to each other with urine drainage end 2 and air bag passage 3, the tube chamber cross section of body 1 is rounded, and external wall cross-section (with the vertical plane of urinary catheter major axis) is quincunx, overall appearance is the blunt multi-edge column-shaped of edge circle, and the side of polygon prism has groove 4.Catheter urine drainage hole 5 is positioned on the seamed edge of nearly conductor ends.As be three chamber types, then wash on another seamed edge that side opening 6 is positioned at nearly conductor ends.
The beneficial effects of the utility model are: use this utility model to be convenient to operation, and minimizing and urethra contact area have reduced the frictional resistance of urethral catheterization, at utmost reduced the damage of indwelling catheter from the physical factor angle to mucous membrane of urethra, and reduce the chemical of secondary, the generation of biological inflammatory factor, simultaneously has the drain lacuna after inserting urethra because of it, urethral secretions there is drainage, reduces the incidence rate of complication such as infection rate and urethral stricture.

The specific embodiment
Use quincunx catheter of the present utility model and carry out urethral catheterization when operation, the method that inserts is with traditional catheter, and after the sufficient lubrication, per urethram collar extension is inserted bladder, among the patient for long term indwelling catheter, fully drain when perineum is nursed, exhaustion external orifice of urethra secretions.Because quincunx catheter and urethral wall contact area and friction area all obviously reduce, so intubate resistance and can obviously reduce to the damage of mucous membrane of urethra.In addition, mucous membrane of urethra secretions can be by the abundant drain of groove spline structure of quincunx catheter, so the inflammatory reaction of urethra can obviously alleviate.
Quincunx catheter is made of jointly urinary catheter body 1 and urine drainage end 2 and air bag passage 3, and urinary catheter body 1 has urine drainage hole 4 and the groove 5 parallel with the urinary catheter major axis.Reduce the urethral catheterization resistance, in drainage of urine, also have the drain of diuresis road mucosa secretions, easy to operate, help the generation of urethral catheterization operation and minimizing urethral catheterization complication.
The groove depth of quincunx catheter can also be changed according to the model difference of urinary catheter, the difference of urinary catheter indwelling time, realizes the individuation urethral catheterization.
The cross section of quincunx catheter can be three lobulateds, four lobulateds, five lobulateds and even more lobulateds, and common feature is the effect that the groove between the different leaflets can play drain mucous membrane of urethra secretions.
The cross section of quincunx catheter can be two chambeies, also can be three chambeies.Can select three chamber types for use for need continuous bladder irrigation person.
Claims (6)
1, a kind of novel catheter that is used for urine drainage, it is characterized in that: at hollow catheter outer surface the drain groove is arranged, its cross section is quincunx.
2, quincunx catheter according to claim 1, it is characterized in that: the groove of urinary catheter outer surface is parallel with the urinary catheter major axis, and depth of groove can be adjusted with the urinary catheter model.
3, quincunx catheter according to claim 1, it is characterized in that: the cross section is quincunx, can be the above polygon of three lobes, as " ten " font of pintongs, the polygon of five lobes etc.
4, quincunx catheter according to claim 1 is characterized in that: urinary catheter external diameter model can be from F8 to F24 and even is bigger, to satisfy the Different Individual needs.
5, quincunx catheter according to claim 1 is characterized in that: can be two chamber type, also can be three chamber types.
6, quincunx catheter according to claim 1 is characterized in that: can be made by soft materials such as medical silica-gels, also can be made by semi-rigid material such as PVC plastics.
