Abstract
The utility model discloses a catheter capable of preventing male urethra injury, which comprises a conical bladder insertion end, a urine drainage opening, an air sac, a catheter in a urethra, an air injecting tube, a drainage tube outside the urethra, a fixed piece and a main body of the catheter, wherein the catheter in the urethra is arranged on the front part in the main body of the catheter, and the urine drainage tube outside the urethra is arranged near the tail end of the main body of the catheter; the air injecting tube is paralleled provided with the catheter in the urethra, the upper end of the air injecting tube is connected with the air sac, the lower section of the air injecting tube extends downwards, and a unidirectional air injecting valve port is arranged on the end opening point of the air injecting tube; the urine drainage tube outside the urethra is folded backwards in the opposite direction corresponding to the catheter in the urethra to be separated from the air injecting tube; the fixed piece which is used for being fixed with abdominal skin of a patient is arranged on the main body of the catheter of the lower section of the air injecting tube. Because the utility model is provided with a urine drainage furcation part, after the fixed piece and the urine drainage tube outside the urethra are fixed, a penis and an ureter on the middle are better protected. The utility model not only can protect the urethra from being injured but also is favorable for clinical care. The utility model has the advantages of simple structure and convenient use, and the catheter can be effectively fixed without bringing pain for patients.
Description
Technical field
This utility model belongs to medical instruments field, relates to the fixable catheter that prevents injury of urethra that urethral catheterization is used behind a kind of male's of being used for surgical operation.
Background technology
In the surgery patients art or postoperative need indwelling catheter, male urethra has its inherent physiological bending, if do not do special handling, the urinary catheter of indwelling produces compressing and causes this position to take place narrow easily to the urethra of penis and scrotum intersection.According to relevant bibliographical information, reach 5～10% because of after the penis and scrotum intersection injury of urethra of urinary catheter due to keeping somewhere narrow percentage rate taking place.
Catheter is fixed to patient's side, is made the physiological bending cut-off at penis and scrotum place can avoid this place's injury of urethra, many clinically at present with silk thread traction catheter to patient's cephalad direction or with the immobilization with adhesive tape penis on hypogastric region skin.Though these two kinds of methods have certain effect, and play certain antisitic defect effect, still have very big inconvenience.At first be that above fixing means is difficult for nursing for medical personnel, and silk thread is fixing is subjected to accident easily and involves, makes and produce friction between urinary catheter and the urethra, the damage urethra.Penis surrounding skin hirsutism, even also have the local skin humidity after scraping hair, fixedly adhesive plaster comes off easily.The drawback of above weak point is exactly the catheter secure detached, causes catheter and turns to patient foot side, makes urethra receive damage, even urinary catheter is connected with urinal and comes off, and patient's clothes is drenched in the urine outflow and bed is elaborate, and intensity is nursed in increase.
Therefore press at present a kind of fixing really, can avoid the urethra physiological bending, reduce the friction of urinary catheter urethra, avoid the male who produces injury of urethra to use catheter.
Summary of the invention
The purpose of this utility model provide a kind of fixing really, can temporarily correct the urethra physiological bending, reduce the friction of urinary catheter urethra, avoid producing the catheter that prevents male urethral injury of injury of urethra.
The purpose of this utility model is achieved in that a kind of catheter that prevents male urethral injury, and there is catheter in the urethra front portion in the catheter main body, is the outer urine drainage pipe of urethra near tail end, and the front end of catheter has the urine drainage mouth in the urethra.Improvements are: in the catheter main body with urethra in catheter be provided with air injection pipe side by side, termination air bag on the air injection pipe, hypomere is straight to be extended downwards, the port is the air injection uni-direction mouth; Catheter near urine drainage pipe outside the urethra of end section with respect to urethra in the catheter inflection reverse, separate with air injection pipe, during use and patient's femoribus internus fix; The outer catheter main body of air injection pipe hypomere is provided with and is used for and the fixed stator of patient's skin of abdomen.Further, also be connected with conical bladder insert head on catheter main body top.
Using method of the present utility model is: according to standard urinary catheter insertion method at ordinary times the catheter main body is inserted urethra, after air bag is given gas, stator is flat on patient's skin of abdomen, with adhesive plaster stator is fixed, place femoribus internus to fix the outer urine drainage pipe of urethra then, the urinal access tube places fixing getting final product under patient's thigh.
Design has a bifurcated near end section because this utility model is in the catheter main body; the outer urine drainage pipe of urethra oppositely separates with the air injection pipe of band stator; purpose is to make the outer urine drainage pipe of urethra can be fixed on femoribus internus; with the convenient urine storage bag that connects; and fix by stator and abdominal part; guarantee urinary catheter physiological bending cut-off; this mode can guarantee that the catheter position is firm; intermediary penis and urinary catheter are under the excellent protection state; both can reduce the friction between catheter and the urinary catheter; avoid injury of urethra, be beneficial to clinical care again.Therefore, the utlity model has characteristics simple in structure, scientific and reasonable, easy to use, can be effectively fixing catheter and can not bring misery to patient.
Description of drawings
Fig. 1 is a structural representation of the present utility model.
The specific embodiment
Referring to Fig. 1, this utility model comprises conical bladder insert head 1, urine drainage mouth 2, air bag 3, catheter main body 4, air injection pipe 5, the outer urine drainage pipe 6 of urethra, stator 7, catheter 8 in the urethra.This kind catheter main body is than common urethral catheterization pipe range, and the front portion in the catheter main body 4 is a catheter 8 in the urethra, and the front end of catheter 8 has urine drainage mouth 2 in the urethra, also is connected with the slick conical bladder insert head 1 of front end on the top of catheter main body 4.Catheter is the outer urine drainage pipe 6 of urethra near end section, and it is reverse with respect to 8 inflection of catheter in the urethra, connects urine storage bag, during use and patient's femoribus internus fix.Catheter 8 is provided with air injection pipe 5 side by side in catheter main body 4 and in the urethra, termination air bag 3 on the air injection pipe, hypomere is straight to be extended downwards, and the port is an air injection uni-direction mouth 9, and the outer catheter main body 4 of air injection pipe hypomere is provided with and is used for and the fixed stator 7 of patient's skin of abdomen.
Claims (2)
1. catheter that prevents male urethral injury, there is catheter in the urethra front portion in the catheter main body, near tail end the outer urine drainage pipe of urethra is arranged, and the front end of catheter has the urine drainage mouth in the urethra; It is characterized in that: in the catheter main body with urethra in catheter be provided with air injection pipe side by side, termination air bag on the air injection pipe, hypomere is straight to be extended downwards, the port is the air injection uni-direction mouth; Catheter near urine drainage pipe outside the urethra of end section with respect to urethra in the catheter inflection reverse, separate with air injection pipe; The catheter main body of air injection pipe hypomere is provided with and is used for and the fixed stator of patient's skin of abdomen.
