Abstract

The utility model relates to a super short urine catheter which is a urethral catheterization utensil made of rubber or silicon gel. The utility model is characterized in that a catheter body is short, and is only one seconds or one eights of the length of the existing catheter at home and abroad. The front end is provided with an air bag or a plum petal, and the tail end is provided with a catheter cap which is accompanied with a catheter core. When left in the urethral canal, the super short urine catheter needs no fixing by adhesive tape, and the fixed program is simplified. The patient can move freely, and the work and study are not influenced. The natural posture urination can be adopted, and the psychic pain of long-term bed of the patient can be exempted.

Description

Super short urine catheter

Catheter is to be used for removing the controlled micturition difficulty, a kind of medical apparatus of drainage of urine.

The urine that the body metabolism process is produced is by renal secretion, through the ureter drain, is stored in bladder.Last per urethra excretes.Whole paths of urine flow warp are called urinary tract.Generally deserve to be called urinary tract from kidney to the Guang internal orifice.One section claims lower urinary tract from the bladder internal orifice to external orifice of urethra.Any position of urinary tract takes place to block or urinates not freely, all is called urinary tract obstruction.

Urinary tract obstruction is one of modal disease of urinary system, the sickness rate height, and consequence is serious.The cause of disease that causes urinary tract obstruction is a lot, as congenital abnormality, inflammation, calculus, tumor, parasitic disease and neural disease.And the inflammation at the contiguous position of urinary tract.Disease such as tumor, scar contracture.Also can cause urinary tract obstruction.Lower urinary tract obstruction particularly.As not removing, can damage urinary tract because of the increase of back-pressure.

The main method of removing lower urinary tract obstruction is interim or long-term indwelling catheter.This just needs ideal urethral catheterization utensil, i.e. a catheter.

China just has human Herba Alii fistulosi pipe to insert the UD urine as far back as twoth century of Christian era.Along with the reach of science.Various catheters are come out one after another.Clinical more common catheter can be divided into metal urethral catheter and rubber urinary catheter substantially.Be hard catheter and soft urinary catheter two big classes.And rubber urinary catheter can be divided into knob catheter, tip catheter, Flos Mume catheter, Foley catheter.

The diameter of existing catheter is 2 millimeters not to be waited to 8 millimeters.Girth according to catheter is called F6 number to F24 number.Can be according to patient's year order, the state of an illness is selected the different count and the urinary catheter of kind for use.

The length of existing catheter all is about 40 centimeters both at home and abroad at present.Being the twice of male urethra, is the octuple of female urethra, oversize because of catheter, inserts urethra and keeps somewhere the back and bring in the action inconvenience to patient, and need with one section very long conduit, catheter is linked to each other with the urine bottle.Patient have to lie in bed motionless.

Task of the present utility model is: designing a kind of novel catheter is ultrashort catheter.This pipe is drawn materials conveniently, is manufactured easily, and program is simple.General curative rubber equipment factory all can manufacture.

Task of the present utility model realizes as follows: ultrashort catheter comprises the ultrashort catheter of Flos Mume and two types of the ultrashort catheter of air bag.Length according to catheter can be divided in men's style and woman style two kinds.The length of in men's style ultrashort catheter is 20 to 22 centimeters.The length of woman style ultrashort catheter is 5 to 8 centimeters, and the diameter all diameter with existing catheter is identical.

Ultrashort catheter is made up of pipe sheath and two ones of tube cores.The tube core of the ultrashort catheter of Flos Mume is than long 2 to 3 centimeters of pipe sheath.And the tube core of the ultrashort catheter of air bag is isometric with the pipe sheath.

Pipe sheath front end has (but 5 to 30 milliliters of gas injection or the water fillings in the capsule of Flos Mume lobe or air bag.) its effect prevents that urinary catheter from coming off.

Pipe shaft is the urinary catheter total length.

The pipe handle be hemispherical, on several apertures are arranged, be passage.The effect of pipe handle is to prevent that urinary catheter from taking off into intravesical.

Pipe cap, effect are to stop the urine outflow, play the timing open effect.The ultrashort catheter of air bag, other is provided with the gas injection arm.

When using ultrashort catheter, need earlier with in the tube core insertion tube sheath Flos Mume lobe to be disappeared, it is straight that the bending section of lobe becomes.After petal enters bladder, tube core is extracted out, the Flos Mume lobe opens thereupon, and the pipe sheath is promptly stayed in the urethra.It is crooked that the tube core front end slightly is.Purpose is along its urethra nature camber, so that can insert smoothly.

The characteristics of ultrashort catheter are that pipe shaft is short and small.Compare with existing urinary catheter and to possess following advantage:

1. existing catheter, pipe shaft are oversize, keep somewhere urethra after, the outside remainder is too many.Because the relation of barodynamics comes off easily.Be difficult to fix.Normally twine catheters, be adhered on perineal position or the penis, very easily after urine is soaked come off, local skin easily goes out erythra with many adhesive plasters.

And ultrashort catheter is by Flos Mume lobe or air bag and pipe handle catheter to be fixed in urethra, and is fixed, without adhesive plaster, avoids erythra to form, and is simplified to fix program, exempts because of come off the repeatedly misery of intubate of catheter.Reduce infection chance.

2. existing catheter, pipe shaft are long, keep somewhere urethra after, need bottle join with very long one section conduit and urine, limited patient's activity, cause spiritual misery.

And ultrashort catheter, volume is short and small, and patient takes the nature position of urinating, and can be with activity, remove from spiritually constraining.Can control voluntarily and urinate, work and study are unaffected.
