The utility model discloses a theory of operation and process:

when the urethral catheter is used, medical personnel firstly take out the urethral catheter device, insert the urethral catheter main body into the urethra of a patient, when the urethral catheter reaches a proper position, inject liquid or gas into the capsule body through the first auxiliary pipe, the urethral catheter main body is fixed in the urethra of the patient under the action of the capsule body, when the water is injected into or inflated into the capsule body, the medical personnel unscrew the first protective cover, inject liquid or gas into the medium injection pipeline through the injector, the first guide pipe arranged on the first auxiliary pipe can guide the injector needle head, the wall of the first auxiliary pipe is prevented from being punctured, the first guide pipe can play a role in preventing the fingers of the medical personnel from being punctured by the injector needle head, the second rubber isolating plug can prevent the liquid or gas in the capsule body from flowing backwards, and the urethral catheter main body is prevented from falling off from the urethra of the patient.

When needs wash patient's bladder, medical personnel are with the second visor, inject the flush fluid to flush fluid injection pipeline through the syringe, the flush fluid gets into the bladder along flush fluid injection pipeline, and wash the bladder inner wall, waste liquid after the washing is external along waste liquid discharge pipeline discharge patient, the syringe needle head can be guided to the second stand pipe that sets up on the second stand pipe, prevent to puncture second stand pipe wall, the second stand pipe can play and prevent that medical personnel from pointing the effect of being punctured by the syringe needle head.

The utility model has the advantages that:

the utility model discloses simple structure, fixed convenient, convenient operation, safe and reliable can still carry out the bladder simultaneously and wash the patient when carrying out the catheterization to the patient, separately the return circuit of flush fluid and waste liquid, avoids flush fluid and the same pipeline of waste liquid use and causes the flush fluid to pollute, avoids the flushing effect to receive the influence, is fit for extensive popularization and application.
