Description

Internal-fixed catheter

This utility model belongs to the internally-fixed catheter that is used as patient's urethral catheterization in the clinical medicine work.Be specially adapted to urine retention that patient causes because of the various causes of disease and danger, heavy patient's clinical rescue and treatment are used.

The at present clinical ordinary urethral catheter that generally uses is to make with rubber products such as silicone rubber, and it is shaped as the slightly sharp and slick and sly flexible tubular body in top, and the top side below has a perforate to use for urethral catheterization.This kind catheter per urethra all needs with adhesive plaster catheter to be fixed on patient's the penis or skin of labium majus after inserting bladder.This fixing means is often many or due to illness the people does not take a shower for a long time that the skin dirt comes off adhesive plaster owing to skin secretion, causes catheter to deviate from; Catheter for the ease of inserting, avoids injuring urothelial in use on the other hand, generally scribbles lubricant, and this also causes adhesive plaster to be difficult to catheter be fixed and come off.Need after catheter comes off to insert again, and insert the chance that will increase patient's urinary tract infection repeatedly; In addition, adopt immobilization with adhesive tape, time to grow and easily cause that local skin festers etc., increase new misery to patient.In order to solve the problem that comes off of catheter, people have designed the internally-fixed catheter of two types of Flos Mume shape and gasbag-types.These two kinds of catheters, the former top have a diameter to be about the Flos Mume shape disking body of φ 27mm, therefore can not be used for inserting urethral catheterization from urethra, can only directly insert bladder and use when the patient needs the surgical incision bladder; And there is an air bag gasbag-type catheter end, and it is very difficult that this air bag makes conduit insert from urethra, and the easy damaged urothelial, so plant hemostasis by compression and the prostatectomy that catheter generally is used for posterior urethral injury.Though above-mentioned two kinds of catheters have the characteristics of internal fixation, can not or be unsuitable for and in clinical, be used as conventional urethral catheterization, and operation and the equal inconvenience of use.

The purpose of this utility model is: according to the advantage and the principle of internally-fixed urethral catheterization, design and a kind ofly both had ordinary urethral catheter to insert urethral catheterization from urethra convenient, versatility is good, simple to operate, safety; Has the Flos Mume shape again and gasbag-type internal fixation catheter does not need adhesive plaster to make external fixation, the internally-fixed catheter of also unlikely advantage such as come off.This catheter is all identical with external form, size and the material of ordinary urethral catheter, and after inserting bladder, can be the Flos Mume shape again in the effect bottom of pulling force, thereby realizes internal fixation; And its end can restore to the original state behind the releasing pulling force.So that its have from urethra insert urethral catheterization and extract out convenient, simple to operate, safe, widely applicable, advantage such as versatility is good.Reach overcome ordinary urethral catheter need with adhesive plaster make external fixation, patient Yi Yin rubberized fabric adhere causes local skin to fester, in use conduit easily comes off simultaneously; And Flos Mume shape and gasbag-type internal fixation catheter can not maybe should not be used for inserting from urethra the purpose of disadvantages such as urethral catheterization clinically.

Solution of the present utility model is on the basis of ordinary urethral catheter, direct-axis line direction is cut three Tiaokous below its urethral catheterization hole, end, each otch on the circumferencial direction of conduit at a distance of 120 ° of whiles above the urethral catheterization hole, a flexible cord or medical thin stainless steel silk are worn as backguy in the inside at the solid position at conduit top, and the termination of this flexible cord or stainless steel silk passes from the top of urinating mouthful or urinating mouthful along catheter lumens.In the clinical practice, after the catheter per urethra inserts bladder, firmly take out and strain at line, enter intravesical end and can be the Flos Mume shape, then backguy is fixed on the catheter outer, thereby make catheter not only play the effect but also the urethral catheterization smoothly of internal fixation.When needing to extract out, backguy is loosened, allowing its end restore to the original state can extract out smoothly.

Effect of the present utility model is, this catheter is because profile is all identical with ordinary urethral catheter with size, material, therefore the not only urethral catheterization of per urethra insertion successfully, and become the Flos Mume shape in the effect downcomer end of backguy after entering bladder, thereby play the effect of internal fixation, do not need immobilization with adhesive tape, yet unlikely coming off.Thereby avoided ordinary urethral catheter in the urethral catheterization process, to need adhesive plaster make external fixation, and easily come off, inserted repeatedly after coming off and easily cause urinary tract infection, and made external fixation with adhesive plaster and also easily cause defectives such as patient's local skin festers; The internally-fixed catheter that this utility model has overcome present use simultaneously again generally can only be used for using behind the bladder cutting operation, and can not maybe should not be used for the disadvantage of routine clinical urethral catheterization.Therefore, the utlity model has from urethra insert easily, safety, extract convenient, simple to operate, difficult drop-off, applied widely, advantage such as versatility is good out.
