The invention discloses an easily-ruptured membrane type total urethral
lubrication catheter and a
catheter drawing and lubricating method thereof, and relates to the technical field of medical catheterization instruments.The easily-ruptured membrane type total urethral
lubrication catheter comprises a catheter body, and a main drainage cavity, an air bag cavity, an air bag and a
lubrication channel which are independent of one another and not communicated with one another are arranged in the catheter body; the main drainage cavity, the air bag cavity and the lubricating channel which are mutually independent are arranged in the catheter, the easily-broken membrane is arranged at the front end of the lubricating channel, the small circumferential lubricating holes are formed in the catheter wall, lubricating liquid is injected before catheter drawing to break the easily-broken membrane,
residual urine is automatically discharged,
liquid injection continues, the lubricating liquid is sprayed out from the small holes in the side wall, and 360-degree even lubrication of the whole
urethra is achieved; the device integrates
residual urine emptying and extubation lubricating functions, is visual in operation, safe and controllable, can be suitable for all people to use, and remarkably reduces extubation pain,
urethra injury and
infection risks, and the structure and the method of the device can be widely applied to long-term indwelling and extubation scenes such as a double-J tube and a trachea cannula.
