Abstract
The utility model discloses a catheter which comprises a catheter main body, a catheterizing channel, a gas-guide channel and a gas bag, wherein the catheterizing channel and the gas-guide channel are formed inside the catheter main body, and the gas bag is covered outside the catheter main body and communicated with the gas-guide channel. The catheter structurally and further comprises a by-pass liquid-guide tube arranged inside the catheter main body. The by-pass liquid-guide tube is communicated with the external world through a diffusion hole in the side wall of the catheter main body. Drainage grooves are formed in the side wall of the catheter main body in a distributed mode. According to the catheter, normal saline or nursing and curing medicine liquid is injected into the catheter through the by-pass liquid-guide tube and flows over from the diffusion hole, not only is a urethra conveniently washed, a urinary tract infection is prevented, damage or adhesion on a urethra mucosa after the catheter is reserved is avoided, and bleeding can be stopped after a urethroplasty or a prostate operation, formation of scars is reduced, good growing environment is provided for anastomotic stomas, meanwhile the drainage grooves can enable the normal saline or the nursing and curing medicine liquid to be fully drained and diffused to the surface of a urethra cavity, a nursing effect is strengthened, and a nursing range is increased.
Description
Technical field
This utility model relates to a kind of catheter, relates in particular to a kind of catheter that urethra rinsed and protected treatment functions that has.
Background technology
Catheter is for being used for urine from intravesical drain medical apparatus and instruments commonly used out after urinate fault or particular procedure.Can meet problems in use procedure, bring misery to the patient; Common are: the one, urinary catheter in easily forms cicatricial adhesion to the mucous membrane of urethra injury in the process of urethra, even cause urethral stricture; The 2nd, long-time indwelling catheter easily causes urinary tract infection because mucous membrane of urethra loses washing away of urine flow warp, especially has more easy infection of wound surface because of urethra after all kinds of particular procedure (as urethroplasty and operation on prostate etc.); The 3rd, anthemorrhagic difficulty after urethra, the urethra anastomosis mouth easily forms cicatrix, affects surgical effect.
The utility model content
The technical problems to be solved in the utility model is to provide a kind of catheter, is convenient to indwelling catheter afterflush urethra, prevents urinary tract infection, avoid mucous membrane of urethra damage or adhesion, postoperative is easy to carry out drug hemostasis, reduces cicatrization, is conducive to total care is carried out in the urethra chamber.
To achieve these goals, technical solution adopted in the utility model is: a kind of catheter, comprise the catheter main body, be arranged on urethral catheterization passage, the air guide channel in the catheter main body and be wrapped in the air bag that the catheter main body is outer and be communicated with air guide channel, also comprise the bypass catheter that is arranged in described catheter main body in its structure, described bypass catheter is connected with the external world by the diffusion hole that is arranged on described catheter main body wall, is distributed with the drain groove on the sidewall of catheter main body.
As a kind of optimal technical scheme of the present utility model, described drain groove distributes as net shape on the sidewall of described catheter main body, and the drain groove is distributed in 1/5 ~ 1/2 place of described catheter body front end.
As a kind of optimal technical scheme of the present utility model, the diffusion hole of the urine filling mouth of described urethral catheterization passage front end, the air bag of air guide channel front end and bypass catheter front end is distributed on the sidewall of described catheter main body from front to back successively.
As a kind of optimal technical scheme of the present utility model, described diffusion hole is arranged on 1/5 ~ 1/2 place of described catheter body front end.
the beneficial effect that adopts technique scheme to produce is: this utility model can or be treated the medicinal liquid that needs and overflow from diffusion hole by bypass catheter saline injection, not only be convenient to rinse urethra, prevent urinary tract infection, avoid after urinary catheter in mucous membrane of urethra injury or adhesion, and can be at urethroplasty or the laggard whereabouts blood of prostate, reduce cicatrization, for anastomotic stoma provides good growing environment, simultaneously, drainage trough can or be treated the surface that the abundant drain of medicinal liquid that needs diffuses to the urethra chamber with normal saline, strengthen nursing or therapeutic effect, increase the scope of nursing or treatment.
Description of drawings
Fig. 1 is vertical cross-sectional schematic of the present utility model.
Fig. 2 is outward appearance side view of the present utility model.
In figure: 1, catheter main body 2, urethral catheterization passage 3, air guide channel 4, air bag 5, bypass catheter 6, diffusion hole 7, drain groove 8, urine filling mouth.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.
referring to attached Fig. 1 and 2, the structure of a specific embodiment of this utility model comprises catheter main body 1, be arranged on the urethral catheterization passage 2 in catheter main body 1, air guide channel 3 and be wrapped in the air bag 4 that catheter main body 1 is outer and be communicated with air guide channel 3, also comprise the bypass catheter 5 that is arranged in catheter main body 1 in its structure, the external mouth of air guide channel 3 and bypass catheter 5 is provided with Trap, bypass catheter 5 is connected with the external world by the diffusion hole 6 that is arranged on catheter main body 1 sidewall, be distributed with latticed drain groove 7 on the sidewall of catheter main body 1, drain groove 7 is distributed in 1/5 ~ 1/2 place of catheter main body 1 front end, the urine filling mouth 8 of urethral catheterization passage 2 front ends, the diffusion hole 6 of the air bag 4 of air guide channel 3 front ends and bypass catheter 5 front ends is distributed on the sidewall of catheter main body 1 from front to back successively, diffusion hole 6 is arranged on 1/5 ~ 1/2 place of catheter main body 1 front end.
this utility model can be in the situation that do not affect the catheter normal function, by bypass catheter 5 saline injections or protect and treat medicinal liquid and overflow from diffusion hole 6, not only be convenient to rinse urethra, prevent urinary tract infection, avoid after urinary catheter in mucous membrane of urethra injury or adhesion, and can be at urethroplasty or the laggard whereabouts blood of prostate, reduce cicatrization, for anastomotic stoma provides good growing environment, simultaneously, drain groove 7 can or protect normal saline and treat the surface that the abundant drain of medicinal liquid diffuses to the urethra chamber, strengthen nursing efficacy, increase the nursing scope.
Foregoing description only proposes as the enforceable technical scheme of this utility model, not as the Single restriction condition to its technical scheme itself.
