Description

Technical Field

[0001] The utility model relates to the technical field of postoperative urinary catheterization, in particular to a urinary catheterization structure used for postoperative urinary system tumor surgery. Background Art

[0002] Urinary system tumors are tumors that occur in any part of the urinary system. They include tumors of the kidney, renal pelvis, ureter, bladder, and urethra. Surgical treatment of urinary system tumors is a common procedure. Catheterization is required after surgery for urinary system tumors. A catheter is a tube that is inserted from the urethra into the bladder to drain urine. It is a tube made of natural rubber, silicone rubber or polyvinyl chloride (PVC). It can be inserted into the bladder through the urethra to drain urine. After the catheter is inserted into the bladder, there is an air bag near the head of the catheter to fix the catheter in the bladder and prevent it from falling out. The drainage tube is connected to a urine bag to collect urine. The Tesla valve is a one-way flow valve invented by scientist Nikola Tesla. It can achieve one-way conduction of the medium without inputting energy.

[0003] At present, most urinary catheters adopt a double-tube structure for urinary catheterization and inflation and gas conduction. Although the double-tube urinary catheter is easy to fix, the urine inside the catheter can flow in both directions, which is prone to urine reflux. When liquid needs to be injected into the body, the double-tube urinary catheter is used for injection. The residue in the urinary catheter interferes with the injection of liquid, and a new injection tube is reinserted, which causes great discomfort to the patient. The urinary catheter has a single structure and function and poor practicality. Utility Model Content

The liquid flows through the second resistance tube 42 in the injection tube body 13 and flows out of the injection tube body 13 from the injection outlet 6. When removing the tube, the tube clamp on the gas guide connector 21 is removed, the balloon ball 3 is discharged, and the catheter body 1 The utility model is composed of a urinary catheter body 11, an airway tube body 12 and an injection tube body 13, which realizes the integrated functions of urinary catheterization and injection after urinary system tumor surgery, and the urinary catheterization and injection are realized in separate cavities, and has strong anti-interference and infection resistance, which can reduce the pain of patients. The catheter structure is stable in use, and a return-blocking mechanism 4 is arranged on the catheter body 1 in the internal space of the airbag ball 3, and the No. 1 return-blocking tube 41 on the urinary catheter body 11 and the No. 2 return-blocking tube 42 on the injection tube body 13 are both Tesla valves, so as to realize the return-blocking function of the urinary catheterization and injection cavity on the catheter, prevent the reflux of urinary catheterization and injection, and avoid the contamination caused by urine entering the injection tube body 13.
