Abstract
The utility model relates to an ureter catheter with prevention of infection, which belongs to the technical improvement of ureter catheters. The wall of the ureter catheter used at present does not have a hole allowing liquid to flow through; when the liquid flows to the ureter catheter, mucus secreted by the urethra is stored in a lacuna between the urethra and the ureter catheter and can not get removed. The utility model is characterized in that more than two holes allowing liquid to flow through are arranged on the catheter wall of the urethra segment of the ureter catheter body to allow the mucus outside the ureter catheter to enter into the inner cavity of the ureter catheter, then the mucus is exhausted out of the body with the urine or with the cleaning liquid, and that ensures that the urethra is free from infection.
Description
The human body urethra is a luminal structure, and it arises from bladder, terminates in external orifice of urethra, multiple bodies of gland such as mucous gland is arranged, secreting mucus etc. in the mucous membrane of urethra.When because of the treatment disease-actual needs, during indwelling catheter, these bodies of gland increase its secretory volume because of foreign body (being urinary catheter) stimulates in urethra.Owing to can not get in the lacuna of these fluid accumulation between urethra and urinary catheter eliminating, the extraneous antibacterial that causes external orifice of urethra is by the up infection of its immobilising fluidity lacuna, even cause diseases such as urethritis, prostatitis, cystitis, epididymis and orchitis, its fundamental cause is that the liquid between urethra and the urinary catheter can not get drain.
The purpose of this utility model provides a kind of urinary catheter cornice liquid-through hole, and the formula urinary catheter is infected in the control that can make liquid between urethra and the urinary catheter obtain drain.
The purpose of this utility model is implemented by following way, promptly on the tube wall of urinary catheter, 2 above liquid-through holes is set.Because it is mobile urine that the control of above-mentioned band liquid-through hole is infected in the formula urinary catheter, no urine flow is the cavity state when moving, pressure is lower, and urinary catheter is outward a mucous membrane of urethra, be subjected to the pressure of surrounding soft tissue and secretions, make the urinary catheter external pressure bigger, the influence of when urine flows, be stressed difference and siphonage, make secretions flow to the urinary catheter intracavity through liquid-through hole all the time, be discharged to external with urine.When urinary catheter was the cavity state, the outer secretions of urinary catheter can flow into the urinary catheter inner chamber more unobstructedly, so the abundant outer liquid in drain urinary catheter chamber of this utility model, played the purpose of preventing and treating infection.In addition, some patient need wash the chamber Guang, because of its pressure is bigger, can wash urethra simultaneously, also plays the purpose that control is infected.
Fig. 1 is first kind of example structure sketch map of the present utility model, and Fig. 2 is the A-A diagrammatic sketch of Fig. 1; Fig. 3 is the structural representation of second kind of embodiment of the present utility model, and Fig. 4 is the B-B diagrammatic sketch of Fig. 3; Fig. 5 is the third example structure sketch map, and Fig. 6 is the C-C diagrammatic sketch of Fig. 5.The utility model is described in further detail below in conjunction with accompanying drawing.
It is single-chamber type that the formula urinary catheter is infected in control shown in Figure 1.The outer section 3 of bladder section 1, urethra section 2 and urethral orifice in urine hole 4 constitutes the body of this urinary catheter by having into, and is an integral body, it is characterized in that being provided with on the tube wall of urethra section 22 above liquid-through holes 5.Figure 2 shows that dual-chamber type control infection formula urinary catheter.Also the outer section 3 of bladder section 1, urethra section 2 and urethral orifice in urine hole 4 constitutes the body of this urinary catheter by having into, and is an integral body.Its feature also is to be provided with 2 above liquid-through holes 5 on the tube wall of urethra section 2.For urinary catheter can be fixed, be fixed with utricule 6 in the front portion of bladder section 1, in the body of urinary catheter, be provided with tube for transfusion 7, tube for transfusion 7 communicates with utricule 6, is provided with non-return valve 8 at the front end of tube for transfusion 7.When indwelling catheter, bladder section 1 is inserted intravesical.In utricule 6, inject liquid by non-return valve 8 and tube for transfusion 7, utricule is heaved, be stuck in the opening of bladder place, urinary catheter can not be gone out.
Figure 3 shows that three chamber type control infection formula urinary catheters.It and dual-chamber type shown in Figure 2 control infection formula urinary catheter difference are to have two lumen roads to feed bladder, can inject liquid continuously, clean bladder, promptly inject cleanout fluid from mouth 9, discharge from mouth 10.
In sum, characteristics of the present utility model are to be provided with 2 above liquid-through holes 5 on the tube wall of the urethra section 2 of body.
