Abstract
This utility model discloses a kind of flushing type three-cavity catheter, comprises urethral catheterization body, and the head end opening of urethral catheterization body enters urine, tail end goes out urine.Urethral catheterization body head end is provided with air bag, and be provided with the loading line logical with airbags in the sidewall of urethral catheterization body, urethral catheterization body tail end is provided with charge valve.Be provided with after urethral catheterization body head end air bag and rinse outlet, be provided with in the sidewall of urethral catheterization body and rinse the flushing line exporting and be connected, urethral catheterization body tail end is provided with flushing valve.The utility model has the advantage of: to rinse after chamber is opened on head end bladder air sac and to have used check valve apparatus, ensure that and rinse the seal of tube chamber, prevent from rinsing tube chamber blocking and bacterial reproduction probability being reduced.Structure is simple: only on original catheter basis, increase a tube chamber, little to the capacity impact of drainage lumens; Reasonable in design: men and women patient all can use; Easy to operate: during use, to inject medicine liquid washing urethral wall and catheter outer wall to flushing chamber, thus at infection source and medium place infection control.
Description
Technical field
This utility model relates to a kind of medical apparatus and instruments, particularly relates to a kind of flushing type three-cavity catheter.
Background technology
Indwelling catheter is the iatrogenic approach that antibacterial enters urinary tract, and urethra or perianal antibacterial can enter urethra along the outer wall of catheter; In addition, urethral catheterization is a kind of store period, has the probability of damage urethra in catheterization procedure, thus makes antibacterial invade urethral mucosa and cause infection.Urinary catheter is placed in urethra for a long time, destroys the normal physiological context of urethra, reduces the mechanical defence capability of bladder to antibacterial, causes antibacterial easily breed and cause infection.Existing catheter has flushing chamber to be still only limited to bladder and the flushing outlet of existing flushing chamber is in open state, the use in chamber is easily rinsed in open flushing outlet by foreign matters from being blocked impact, also easily cause antibacterial in the breeding of flushing intracavity, can not effectively from infection source and medium infection control.
Summary of the invention
The purpose of this utility model is to provide a kind of novel reduced intubate to cause the three-cavity catheter of urinary tract infection incidence rate.
The technical solution of the utility model is: a kind of flushing type three-cavity catheter, comprises urethral catheterization body, and the head end opening of urethral catheterization body enters urine, tail end goes out urine.Urethral catheterization body head end is provided with air bag, and be provided with the loading line logical with airbags in the sidewall of urethral catheterization body, urethral catheterization body tail end is provided with charge valve.Be provided with after described urethral catheterization body head end air bag and rinse outlet, be provided with in the sidewall of urethral catheterization body and rinse the flushing line exporting and be connected, urethral catheterization body tail end is provided with flushing valve.
The flushing chamber increased is opened on the rear of head end air bag, for injecting medicine liquid washing urethral wall and catheter outer wall infection to the lacuna between urethral wall and catheter outer wall.
The flushing opening part rinsing chamber head end is provided with check valve, ensures the seal rinsing chamber.
The utility model has the advantage of: to rinse after chamber is opened on head end bladder air sac and to have used check valve apparatus, open flushing opening different from the past, ensure that and rinse the seal of tube chamber, prevent from rinsing tube chamber blocking and bacterial reproduction probability being reduced.Structure is simple: only on original catheter basis, increase a tube chamber, little to the capacity impact of drainage lumens; Reasonable in design: men and women patient all can use; Easy to operate: during use, to inject medicine liquid washing urethral wall and catheter outer wall to flushing chamber, thus at infection source and medium place infection control.
Accompanying drawing explanation
Fig. 1 is this utility model flushing type three-cavity catheter structural representation;
Fig. 2 is this utility model flushing type three-cavity catheter A-A sectional view.
Detailed description of the invention
As shown in Figure 1, a kind of flushing type three-cavity catheter, comprises urethral catheterization body 3, the head end of urethral catheterization body 3 has urine filling mouth 1, tail end is urine outlet 9, and the head end of urethral catheterization body 1 is provided with air bag 2, and it is charge valve 5 that the sidewall of urethral catheterization body 3 is provided with its tail end of gas tube 4 be communicated with air bag.Air bag 2 rear is syringe pipe opening 7, and the sidewall of urethral catheterization body 3 has its tail end of syringe pipe 8 to be flushing valve 10.There is check valve 6 at syringe pipe opening 7 place.Check valve is in closed condition under normal circumstances, the syringe not with pin is plugged by syringe pipe 8 tail end flushing valve 10 after inserting catheter during use, with certain pressure, medicinal liquid is injected tube chamber, check valve is opened automatically, and the lacuna that flushing liquor enters between urethral wall and catheter outer wall completes flushing.Sterilization water flushing tube chamber can be injected in flushing tube chamber when injecting liquid drug is complete, rinse rear open end check valve and automatically close, now by rinsing the residual liquid pumpback of intracavity, medicinal liquid Crystallization Plugging tube chamber can be prevented.Finally pull up syringe, the setting of check valve ensure that the seal of tube chamber.
Structure of the present utility model is not limited only to above-mentioned disclosure, and other improvement without creative work are also in this utility model protection domain.
Claims (2)
