Three-cavity catheter plug body
Technical Field
The utility model belongs to the technical field of medical appliances, and particularly relates to a three-cavity catheter plug body.
Background
The three-cavity air sac catheter has three cavities including water filling port, liquid outlet and flushing port. The water filling port is used for inflating or injecting liquid into the air bag near the head end of the catheter to fix the catheter, the liquid outlet is connected with the urine bag to collect urine, and the flushing port is connected with the flushing liquid to flush. Three-lumen balloon catheters are commonly used in patients who require continuous bladder irrigation for urinary surgery post-operative bladder or prostate bleeding in order to prevent or reduce blood clot formation.
In clinical practice, after the continuous bladder irrigation has ceased, the irrigation port needs to be closed to maintain the sterility and tightness of the catheter. Currently, the main flow three-cavity urinary catheters used in the market have no special and independent sealing plug body. Some catheter tips, although provided with a plug body, are connected to the irrigation port and cannot guarantee their sterility during continuous bladder irrigation because they are exposed to contamination for a long period of time. Still some cystostomies are reluctant to carry a drainage bag for a long period of time, and likewise require a special stopper to seal the catheter to form a sterile passageway. Thus, patients who either continue bladder irrigation to stop or have a need to pinch the urinary tract often need to have some temporary substitutes to seal them, with the disadvantage of inconvenient use. There are literature reports that disposable heparin caps can be used for sealing. However, the catheter has the disadvantages of softer flushing port without support, cylindrical heparin cap, difficult insertion and removal, plugging with the cap at the head end of the drainage bag, falling risk due to the fact that the size of the cap is not fit, blocking with a large needle cap, clamping with a clamp, and the like, is neither standardized nor attractive, and is easy to fall off, so that the chance of urinary tract infection is increased. In summary, currently, three-lumen balloon catheters do not have a suitable, independent, dedicated plug body to seal the irrigation port during the cessation of continuous bladder irrigation. Therefore, the three-cavity catheter plug body is provided for achieving the purpose of higher practical value by researching and improving the existing structure and the existing defects.
Disclosure of utility model
In order to solve the technical problems, the utility model provides a three-cavity catheter plug body, which is achieved by the following specific technical means:
The three-cavity catheter plug body comprises a main body and a cap, wherein a through hole is formed in the center of the main body, the plug body is integrally arranged on the outer side of the main body and is of a conical structure, the plug body is provided with multiple sections, and the diameter of the plug body is sequentially reduced from top to bottom.
Further, a connecting ring is integrally formed on the top end of the main body, and the outer side of the connecting ring is in threaded connection with the inner side of the cap.
Further, a connecting pipe bolt for connecting the injector is integrally formed on the top end of the main body corresponding to the through hole, and the top end of the connecting pipe bolt penetrates through the connecting ring and is located on the top side of the connecting ring.
Further, the cap is provided with a containing hole for containing the connecting pipe bolt.
Further, the plug body is made of ABS plastic.
Compared with the prior art, the utility model has the following beneficial effects:
According to the utility model, through the cooperation of the connecting ring and the cap, the cap can be conveniently and quickly disassembled from the connecting ring, and the flushing port on the catheter is closed, so that a closed sterile passage is formed between the catheter and the flushing port, and the catheter and the flushing port are prevented from being polluted by the outside in the long-time use process.
According to the utility model, through the conical structure of the plug body, the plug body can be mounted in flushing ports with different inner diameters, and meanwhile, the plug body can be mounted on other similar drainage tubes, so that the applicability of products is increased.
