Description
[ technical field ] A method for producing a semiconductor device
The utility model relates to the field of medical equipment, concretely relates to nested formula prevents blockking up catheter.
[ background of the invention ]
The catheter is a pipeline made of natural rubber, silicon rubber or polyvinyl chloride, can be inserted into the bladder through the urethra to drain urine or blood clots, and is connected with a urine bag through a drainage tube to collect the urine or blood clots after being inserted into the bladder.
During the use of the catheter, the catheter is directly connected with the urethra and inserted into the bladder, and after operations such as prostate cancer operation, prostatic hyperplasia operation or bladder tumor electrostomy, bleeding or floccule is often caused, the catheter is generally thin, and in the process that the floccule or blood clots flow out through the catheter, blockage is easily caused, so that urine cannot be discharged, and secondary infection is caused.
[ Utility model ] content
The to-be-solved technical problem of the utility model lies in providing a nested formula prevents blockking up the catheter, and it dredges the catheter that blocks up, and then avoids the catheter to be blockked up by the clot or flocculent necrotic tissue to lead to the unable exhaust problem of urine.
The utility model discloses a realize like this:
the utility model provides a catheter is prevented blockking up by nested formula, includes outer catheter, interior catheter, outer sacculus, interior sacculus, first air pump and second air pump, the catheter outside including outer catheter cover is established, interior catheter head and afterbody all extend out outer catheter, the lateral wall of catheter head end is established outside to outer sacculus cover, the head lateral wall of catheter including interior sacculus cover is established, first air pump links to each other with outer sacculus, the second air pump links to each other with interior sacculus.
Furthermore, the tail end of the outer urinary catheter is provided with an internal thread section, the tail end of the inner urinary catheter is provided with an external thread section, and the internal thread section is in threaded connection with the external thread section.
Further, a sealing ring is arranged between the outer catheter and the inner catheter.
The utility model has the advantages that:
the utility model is provided with the nested internal catheter and the nested external catheter, realizes the dredging function by pulling the internal catheter, and can loosen the accumulation of blood clots or flocculent necrotic tissues in the pulling process, thereby dredging the blocked catheter; at the moment, the inner catheter has the function similar to a dredging rod, and the outer catheter has the function of sliding the sheath tube, so that the recanalization can be realized; because outer catheter provides a space of drawing and twitching for interior catheter, can prevent that catheter and urethra direct friction from producing the damage. The utility model is also provided with an outer balloon which is used for fixing the outer catheter when the inner catheter is pulled and pulled so as to prevent the outer catheter from falling off from the urethra; the utility model discloses the interior sacculus that sets up for when normally using the catheter, fixed interior catheter and urethra prevent that it from droing from the urethra.
[ description of the drawings ]
The invention will be further described with reference to the following examples with reference to the accompanying drawings.
Fig. 1 is a schematic view of the nested anti-clogging catheter in a normal use state.
Figure 2 is the utility model relates to a nested formula prevents blockking up state schematic diagram of mediation of catheter.
Fig. 3 is a schematic view of the nested anti-clogging catheter with a sealing ring.
