The invention discloses a novel painless ultra-smooth antibacterial
catheter which structurally comprises an air bag, a
catheterization device, a
catheter body, a sampling tube, a connecting tube, an inflation water injection tube and a
urination catheter.When the novel painless ultra-smooth antibacterial catheter is used and when a doctor carries out
intubation, a sleeving opening is matched with the catheter body and extends into the bladder through the
urethra, normal
saline is injected into the air bag through the inflation water injection tube, and the catheter body is inserted into the air bag through the
urine injection tube; when catheterization is carried out,
urine flows into the catheter body through the
butt joint opening and makes contact with the flow slowing
assembly, the flow slowing
assembly plays a role in buffering and
speed reduction on the
urine, the urine can stably flow to the movable expansion piece in the catheter body under the action of the multiple inclined sliding plates, and therefore the catheter can be conveniently and rapidly guided. When the urine flows out, the movable expansion piece is opened downwards under the downward
impact force of the urine, the urine flows to the guiding-out
assembly along with the movable expansion piece, blood clots in the urine are treated through the guiding-out assembly, and the urine can be discharged outwards in time.
