Definitions
- the invention relates to the technical field of medical instruments, in particular to a urine drainage device, a drainage control device, a drainage control system and a urination method.
- the catheterization device used in conventional indwelling catheterization consists of a catheter inserted into the urethra and a urine bag connected to the lower end of the catheter.
- the urinary catheter continuously leads the urine in the bladder, resulting in the formation of normal intravesical pressure in the bladder.
- the patient's detrusor and intravesical sphincters are in a state of disuse for a long time, unable to use low-pressure urine storage and low-pressure urination.
- the principle of urinary control protects the entire urinary tract system. Long-term use of this type of catheter has the following risks:
- the pressure sensor By setting a preset pressure, the pressure sensor is used to collect the bladder pressure, and when the bladder pressure continues to reach or exceed the preset pressure. The distance of the pressure is determined to be equal to or greater than the preset time. If the duration is equal to or greater than the preset time, the control component alarms to urinate or automatically open the urination, and automatically closes the catheter after the urine is discharged. This process simulates people The normal physiological urination of the body avoids the loss of bladder function caused by the continuous catheterization of the catheter in the traditional catheterization mode.
