The outer side wall of the boss and the communicated part of the groove bottom B corresponding to each flushing hole 3 and the annular groove B8 are respectively provided with a matched spiral groove 12 along the water spraying direction of the flushing hole 3, and the groove bottom C of the spiral groove 12 is parallel and flush with the inner side groove wall of the annular groove B8 and is parallel and flush with the outer side wall of the joint of the filter screen cover B7 and the boss.
Flushing hole 3 evenly divide into the multiunit and washes the punch combination, and every group washes the punch combination and comprises a plurality of adjacent flushing holes 3 in proper order respectively, and every flushing hole corresponds in the every group washes the one-way valve interface B16 respectively with the different feed liquor pipe intercommunications that washes to the one-way valve interface B16 that the corresponding flushing hole 3 in every group washed the punch combination corresponds respectively with the same feed liquor pipe intercommunication that washes, wash the feed liquor pipe and equally divide and do not communicate with washing unit.
An annular groove C18 is formed in the end face of the urinary catheter 1 and the edge corresponding to the filter screen cover A6, and the edge of the filter screen cover A6 is fixedly connected into the annular groove C18.
The one-way valve port A15, the one-way valve port B16 and the one-way valve port C17 respectively extend out of the catheter 1.
When the catheter is used, the insertion end of the catheter 1 is inserted into a bladder from a urethra, then the one-way valve port C17 is connected with the inflation hole 14 and is communicated along the direction from the external end to the insertion end, then the inflation device inflates air into the annular air bag 4 through the one-way valve port C17 and the inflation hole 14, when the annular air bag 4 is filled with air, the annular air bag 4 relatively fixes the catheter 1 and the urethra, and the cover plate unit 10 fixed to the annular air bag 4 supports open the mesh enclosure 9; at this time, large clots and large stones in the bladder are blocked by the meshes of the mesh enclosure 9, urine, and some clots or stone particles in the bladder can pass through the meshes of the mesh enclosure 9, and then the blood clots or stone particles are blocked outside the mesh enclosure a6 or the mesh enclosure B7 due to the effects of the mesh enclosure a6 and the mesh enclosure B7, while the urine can still pass through the mesh a of the mesh enclosure a6 and the mesh B of the mesh enclosure B7 respectively and smoothly; the one-way valve port B16 is communicated along the direction from the external end to the insertion end, and urine in the bladder cannot enter the washing hole 3 under the action of air pressure in the washing hole 3; therefore, the urine in the bladder can only be outwards induced and flow out to the urethral catheterization bag through the urethral catheterization through hole 2 and the one-way valve port A15. When the catheterization is performed through the catheterization through hole 2, urine in the bladder flows to the catheterization through hole 2, after blood clots and stone particles in the urine are blocked by the mesh enclosure 9, the mesh enclosure a6 and the mesh enclosure B7, part of the blood clots and stone particles are clamped or adsorbed on the outer surface of the mesh enclosure 9, the outer surface of the mesh enclosure a6 and the outer surface of the mesh enclosure B7 under the action of the urine, and then the mesh a of the mesh enclosure a6 or the mesh B of the mesh enclosure B7 is partially blocked; the sizes of blood clots or stone particles which can pass through the mesh A of the filter screen cover A6 and even can pass through the mesh B of the filter screen cover B7 can completely pass through the urethral catheterization through hole 2; when the urine flowing out of the urine guide bag from the urine guide through hole 2 and the one-way valve port A15 is slow all the time, the blockage of the filter screen cover A6 or the filter screen cover B7 of the urine guide can be judged, the blockage degree can be judged according to the slow urine flowing out speed, and then one or more groups of flushing hole groups are selected according to the blockage degree to flush the filter screen cover A6 and the filter screen cover B7 in the bladder; when the flushing hole 3 is flushed, flushing liquid in the flushing liquid inlet pipe enters the corresponding flushing hole 3 through the check valve port B16 and then moves towards the insertion end of the urine guide pipe 1 along the flushing hole 3, when the flushing liquid is positioned at the tail end of the flushing hole 3, the moving direction of the flushing liquid is changed into spiral movement towards the insertion end of the urine guide pipe 1 due to the structure of the flushing hole 3, the flushing liquid is sprayed out along the direction from the groove bottom B of the annular groove B8 to the notch B after leaving the flushing hole 3 to enter the annular groove B8, and due to the structure of the connection part of the flushing hole 3 and the groove bottom B of the annular groove B8, the flushing liquid sprayed out from the flushing hole 3 is sprayed outwards along the angle of the connection part of the flushing hole 3 and the groove bottom B of the annular groove B8 to the direction of the same side tangent line where the flushing hole 3 is positioned relative to the center of the urine guide pipe 1; the flushing liquid sprayed out of the notch B of the annular groove B8 is sprayed to the filter screen cover A6, blood clots or calculus particles clamped and adsorbed on the outer surface of the filter screen cover A6 are separated from the outer surface of the filter screen cover A6 under the action of the flushing liquid and flush out of the outer side of the screen cover 9, and when the blood clots or calculus particles located between the screen cover 9 and the filter screen cover A6 flush out of the screen cover 9 under the action of the flushing liquid, part of the blood clots or calculus particles can impact and touch the screen cover 9, and under the action of the flushing liquid, part of the blood clots or calculus particles impacting and touching the screen cover 9 can be flushed away and part of the loose calculus particles can be flushed away; divergent rotary spray can make the washing angle range of the washing liquid wider. In addition, part of the washing liquid is sprayed outwards along the groove 12, so that blood clots or stone particles clamped and adsorbed on the outer surface of the filter screen cover B7 are separated from the outer surface of the filter screen cover B7 and washed out of the outer side of the filter screen cover A6; meanwhile, the washing liquid can also make the blood clots or calculus particles between the filter screen cover A6 and the filter screen cover B7 impact and touch the filter screen cover A6, and under the action of the washing liquid, the blood clots or part of the blood clots in the calculus particles impacting and touching the filter screen cover A6 can be dispersed and part of the loose calculus particles can be broken; therefore, the urethral catheterization can be continued smoothly, and the blood clots and calculus particles in the bladder can be dispersed and broken and then discharged together with urine, so that the urethral catheterization is further facilitated smoothly.
When the air bag needs to be taken out, the check valve port C17 and the inflation hole 14 are directly connected in the reverse direction and are communicated along the direction from the insertion end to the connection end, the check valve port C17 is connected with the air extractor, air in the annular air bag 14 is exhausted to be vacuum through the air extractor, the contracted annular air bag 14 is fixed in the annular groove A13 under the action of the cover plate unit, and meanwhile, the net cover 9 is also retracted; the catheter 1 is then pulled out of the urethra.
