The invention relates to the field of
urinary catheterization devices, in particular to an anti-falling
urinary catheterization device for pediatric urinary
surgery. Comprising a connector, a connector is fixedly communicated with the connector, one end of the connector is detachably, fixedly and hermetically connected with a
vacuum pump, a blocking valve is arranged on the connector between the
vacuum pump and the connector, the other end of the connector is detachably, fixedly and hermetically connected with one end of a
catheter, and the other end of the
catheter is fixedly communicated with a shell. A floating block is slidably arranged at the end, away from the
catheter, of the shell, a plurality of
urination holes are evenly formed in the circumference of the end, away from the catheter, of the shell, and the
urination holes can be sealed and blocked when the floating block makes contact with the shell. Before the
urethral catheter is inserted, the
vacuum pump can vacuumize the inside of the
urethral catheter, the
diameter of the
urethral catheter can be reduced, the urethral catheter can be conveniently inserted after the
diameter of the urethral catheter is reduced, the pain of a patient can be reduced in the urethral
catheter insertion process, and the urethral mucosa is prevented from being damaged by the urethral catheter.
